In this way, in the next few days, Pang Xiaonan accompanied Zhao Sijiajia to practice fighting in the morning, Zhao Sijiajia accompanied Pang Xiaonan to practice dodging bullets, Pang Xiaonan's dodging kung fu gradually improved, and in the end, he could easily dodge the shooting of plastic bullets even if he didn't turn on his spiritual sense, so he asked Zhao Sijiajia to speed up his aiming.

And Zhao Sijiajia In the process of shooting Pang Xiaonan, as Pang Xiaonan's dodging skills became more and more proficient, her own marksmanship has also improved greatly, and she can basically put the gun at will, without deliberately aiming.

In the past few days, Pang Xiaonan has not been out of the Hailong community, he is worried that Nangong Jim has hired other killers to wait for him outside, and at the same time he called Xiong Junjun and told her that she should not leave the school if she has nothing to do, the school is closed management, at least it is safer than outside.

One afternoon, Pang Xiaonan received a message from the old blacksmith, saying that the flying knife had been made and asked him to have time to go over and get it. Pang Xiaonan was overjoyed, "I finally have a weapon to take advantage of!"

"No matter what, I'm going to go out!" Thinking of this, Pang Xiaonan didn't care about any gunman outside, with his current cultivation, as long as the other party was not a yin gun, he had the ability to dodge at least one shot, and if he could dodge, he would have the opportunity to escape and even find a chance to fight back.

Pang Xiaonan dressed up a little, or took the time he went to Hehai Mansion as a model, trying to dress up a little taller, and distinguish himself from the previous Pang Xiaonan, so that the killer was not so easy to recognize himself.

Then he got his hair a little bit, and there was no Morse at home, so he took an egg and beat it in a bowl, and then applied the egg liquid to his hair, combed it back, and made a big back, "Well, it's a bit of a big brother style." ”

Pang Xiaonan went out, still drove the shepherd towards the old city, he didn't find anyone following along the way, so he parked the car not far from the blacksmith shop, and then walked towards the blacksmith shop vigilantly.

The old blacksmith was clanging on a piece of reddish iron, and when he saw Pang Xiaonan coming in, he didn't stop, and said to Pang Xiaonan: "You sit down for a while, and I'll come over after beating this piece of iron." ”

Pang Xiaonan copied a bench at random, chose a position facing the door and sat down, the temperature in this blacksmith shop was really high, he kept fanning the wind with his hands, his eyes were staring at the world outside the door, the light was a little dazzling, and after a while he felt that his eyes were a little dazzling, so he withdrew his gaze and only stared at the door frame.

"What are you looking at?" The old blacksmith finally finished his work and walked towards Pang Xiaonan.

"Nothing, look at the view outside the door, there is a dog there. Pang Xiaonan pointed out the door, there was indeed a dog, it should be two dogs doing ancient exercises, one up and one after the other very rhythmic.

"Hehe, so you like to watch this. The old blacksmith took a belt and handed it to Pang Xiaonan, copied a stool and put it next to Pang Xiaonan, and then went to get his hookah.

Pang Xiaonan said: "Where is it, I don't like to look at it, but the two of them don't look at the place, and they just happened to crash into my eyes." He took the old blacksmith's belt in his hand and looked at it carefully.

This belt is a faint brown yellow, it can be seen that it is the primary color of real cowhide, a simple buckle, a few holes have been opened on the belt, easy to buckle, different from the general belt, the middle part of the belt is relatively wide, is a two-layer design, there is a certain gap between the two pieces of skin, just inserted into a flying knife, the handle of the flying knife is exposed, is made of pure copper, and the above is a simple texture, which is convenient to increase the friction of the fingers.

Pang Xiaonan drew a flying knife out, the blade of the knife is the weird and beautiful black of the spirit stone, flashing with a breathtaking light under the reflection of the fire, the blade is inlaid on the earthy yellow pure copper handle, the whole knife looks simple and gorgeous, if it is an ordinary person to see, will think that this is where the unearthed cultural relics.

Pang Xiaonan gently swiped the side of the blade across his fingers, and he could feel the sharpness of the blade. He stretched out his thumb and forefinger, pinched the handle of the knife and aimed the blade straight at the ground, then let go of his hand, and the tip of the knife fell down, and poof, the knife was straight into the ground.

"Awesome!" Pang Xiaonan exclaimed sincerely, the ordinary knife, falling to the ground, at most smashed a mark on the ground, and this flying knife can be inserted into the ground, one is to explain the sharpness of the tip of the knife, the second is to show that the flying knife is very precise, can maintain the balance of the knife body, and the third is to show that the spirit stone material is special, without the toughness of metal, hard is better than iron.

Pang Xiaonan took out the flying knife from the ground, brushed the faint dust off the knife with his fingers again, turned his head and said to the old blacksmith: "Old man, your flying knife is so good. ”

The old blacksmith smiled and said, "It's still your material is good, I've been striking iron for so many years, it's the first time I've encountered such a rare material as yours, to be honest, the hardness of your material may be many times better than steel, and I've scrapped a lot of grinding sand discs, but after I hit it, I tried it, and the iron was sharpened like mud, which was not fake at all." ”

Pang Xiaonan inserted the flying knife into the belt and said: "The material is good, but in the final analysis, your craftsmanship is good, I won't talk about the workmanship of the flying knife, just this belt, that is the level that can participate in the fashion show, old man, I thought you were a blacksmith, it turns out that you still know clothing design." ”

Pang Xiaonan is not flattering, the design and workmanship of this belt are not inferior to the seven flying knives, with both practicality and fashion style, as well as this pure natural material, every detail shows the designer's profound skills.

The old blacksmith waved his hand, the corners of his mouth raised, and the wrinkles on his face became more profound, "Don't say pretty words about you kid, my belt is nothing more than tailored according to the characteristics of the flying knife, there is no design or design, but when you insert the flying knife, pay attention not to cut the leather surface, although I am the first layer of cowhide, but your flying knife is too sharp, if you always cut the leather surface, the belt will be worn out." ”

Pang Xiaonan nodded and said, "Well, I know, I will take good care of the belt, old man, I admire you more and more, I thought you were a simple blacksmith, now it seems that you are an all-round design talent, I let you play a few flying knives, you even consider the matching knife cover and how to carry it conveniently, admire and admire." ”

Saying that, Pang Xiaonan stood up, buckled the belt to his waist, jumped slightly, tried the comfort and tightness, and said, "Well, yes, it's quite suitable." ”

"It's just suitable, I also roughly visually checked your size, so I made a few more holes to make it easier for you to adjust. The old blacksmith lit his cigarette and smoked it.

"Old man, aren't you curious about what I'm doing with this flying knife?" Pang Xiaonan untied the belt, sat back on the stool, and put the belt on his lap.

The old blacksmith smoked until a pinch of tobacco turned into ashes, then took off the pipe and knocked the tobacco on the floor, and then said to Pang Xiaonan: "I usually don't ask the purpose of the customer, hehe, you fight this flying knife, it is definitely not fun, this is in the hands of people with strong martial arts, it is a weapon to kill, so I still advise you, it is usually best to use it sparingly, as long as you make a move, this thing will cause irreparable damage and consequences." ”

Pang Xiaonan smiled, stood up and said, "Don't worry, old man, I won't use this flying knife unless it is absolutely necessary, just like you said, once the flying knife is shot, the consequences will indeed be irreversible." Thanks, I'll go first. ”

Pang Xiaonan took out his mobile phone, opened the flying falcon and transferred the fee to the old blacksmith, then took the flying knife belt out of the blacksmith shop and went home happily.

The first thing he did when he entered the door, Pang Xiaonan ran into the practice room, and he wanted to try the power of this flying knife.

When he arrived at the practice room, Pang Xiaonan looked left and right, thinking about what to use as a target, thinking about it, it was better to try the apple first, so he trotted all the way into the kitchen, took out an apple from the refrigerator, and then trotted all the way back to the practice room.

Pang Xiaonan carefully placed the apple on the bench, and then walked to a place ten meters away from the apple, concentrating and positioning the apple in his mind.

Then, Pang Xiaonan tied the belt to his waist, took out a flying knife from the holster with his right hand, and set his eyes on Apple's body again.

2 seconds later, Pang Xiaonan's eyes flashed, and then with a flick of his right hand, a flying knife flew out, only to hear a "bang", the apple shattered into slag, and the flying knife was inserted straight into the wall behind the apple.

"It's amazing!" Pang Xiaonan was very satisfied with the power of the flying knife, because this time he threw out the flying knife purely relying on the power of the flying knife itself, without infusing any spiritual power, and it was already unexpected to be able to achieve the effect of the apple crumbling into slag.

"Apples are too brittle, are there any harder targets to try?" Pang Xiaonan looked left and right in the practice room again, but unfortunately he didn't see anything suitable for making a target after looking at it for a long time, so he remembered the cutting board in the kitchen.

"Eh, the cutting board is made of wood, it's a lot harder than an apple, yes, try it. So Pang Xiaonan trotted all the way into the kitchen, took the cutting board from the dining table, and then trotted all the way back to the practice room.

Later, Pang Xiaonan thought of a way to use the armrests and backrests of the bench to place the chopping board horizontally in the middle, forming a triangle with the armrests and backrests.

It is equivalent to the side of the bench aligned with Pang Xiaonan, and the cutting board is one side of this side. In this way, the cutting board is stable, but the difficulty of aiming is increased, because Pang Xiaonan can only aim at the thickness of the cutting board, not the surface of the cutting board.

"it, just practice my accuracy. Pang Xiaonan walked directly across from the side of the bench, about eight to nine meters from the cutting board.

This time, Pang Xiaonan first touched the flying knife, set the position of the cutting board with his spiritual sense, and then poured his spiritual sense into the flying knife in his hand, and looked at the cutting board for 1 second, and then suddenly shook his hand, the flying knife broke out of the air, making a sharp roar, only to hear a loud "bang", the cutting board split apart, Pang Xiaonan was slightly excited in his heart.

When the crumbs of the chopping board dissipated, Pang Xiaonan walked up, and he found that the chopping board was not as simple as falling apart, it could be described as broken bones, and it was difficult to find a piece of wood larger than 5 cm square. "Well, with the flying knife of spiritual power, the effect is so amazing, it should be no problem to penetrate a person's body. ”

Pang Xiaonan was not satisfied, and wanted to try the last one again, so he looked around in the practice room again, and finally his eyes were fixed on the huge sandbag.

"Well, that's good, at least it's about the size of a life-size. "This sandbag in Pang Xiaonan's practice room is much larger than ordinary sandbags, and the weight of the sand is nearly 200 kilograms, it is difficult to make the sandbag swing with one punch.

"That's you. This time, Pang Xiaonan didn't even aim, he directly took out a flying knife from his belt and shook his hand, and threw the flying knife out in one go. At the same time as he threw the flying knife again, he had already quickly input the spiritual power into the flying knife in his mind.

There was another loud "bang," like the sound of a bomb bursting, and the entire sandbag was blasted! The sand in the sandbag flew around, forming a huge cloud of smoke, and the practice room was suddenly filled with dust, and Pang Xiaonan, who was choking, coughed again and again, and couldn't open his eyes.

It wasn't until a long time later that the dust from the sandbag blasting subsided, falling to the ground to form a thick layer of dust, seeing a mess, Pang Xiaonan was excited with a trace of regret, "Damn, I knew that the power was so great, I really shouldn't use it as a target, the ash in this place has to be cleaned." ”

The ground of the practice room was full of sawdust, sand, and dust, which was dirtier than the decoration site, Pang Xiaonan helplessly took a broom and a garbage basin, and began to clean with one hand and one foot, mixed with the cough sound of him choking on the dust.

was cleaning, Pang Xiaonan felt the mobile phone in his trouser pocket vibrating, and then the phone rang, Pang Xiaonan took out his mobile phone and saw that it was Councilor Wang calling.

"Hey, Lao Wang, do you have any advice?...... What, invite me to dinner, okay, 6 o'clock in the evening, okay, see you soon. After hanging up the phone, Pang Xiaonan's mood was a little better, although cleaning the room made him a little tired, but dinner was settled, which made his stomach feel a little relieved.

It took nearly two hours to clean up the chicken feathers in the practice room, although the whole room was still a little dirty and polluted by dust, but Pang Xiaonan collapsed on the bench and exhaled a long breath of turbidity, "Don't do it, so be it, anyway, the practice room doesn't need to be used to sleep, so be it, don't do it." ”

He didn't have the patience to let him scrub the whole house with a rag. Pang Xiaonan rested on the bench for a while, went to the shower room to wash off the dust, changed into a set of clean clothes, went out with a small song, and slowly paced to Councilor Wang's villa.

Knocking on the door, it was Su Xiaomei who opened the door as usual, and when she saw that it was Pang Xiaonan, she was like a relative who had not seen her for a long time, and greeted warmly: "Xiaonan, come in, Councilor Wang is waiting for you to eat." ”

Pang Xiaonan was not polite, he walked straight to the restaurant, and saw that the table full of delicacies had been prepared, but Councilor Wang was not next to the table, he knew that Councilor Wang was still in the study upstairs, so he walked to the staircase and shouted to it: "Lao Wang, it's time to eat, Lao Wang ......"

After a while, he heard footsteps coming from upstairs, and Councilor Wang replied at the top of his voice: "Coming, coming......"

Pang Xiaonan and Councilor Wang both sat down, and Su Xiaomei went to the side hall to eat with the servants, leaving only Pang Xiaonan and Councilor Wang in the restaurant, because she knew that the two of them must have something to discuss.

Pang Xiaonan was also not polite, took a piece of back to the pot and chewed it in his mouth, and asked at the same time: "What about Brother Peng Yuyan Peng, didn't you come back?"

Councilor Wang poured wine on the side and said: "He usually doesn't come back for dinner, although he doesn't go out to socialize, but there are always some dinners, even if there is no dinner, he will work until late to come back, after all, such a big company, there are too many things." ”

Pang Xiaonan nodded frequently, "Well, this time the meat in the pot is good, fat but not greasy and chewy, and the mouth is full of meat." It's a pity that Brother Peng doesn't have this mouthful. ”

Councilor Wang pushed the bad ones in front of Pang Xiaonan and said, "I heard that you have been targeted by a killer recently?"

Pang Xiaonan nodded and said, "It was Peng Yuyan who told you, that's right, he was targeted by the killer, and he was a master of using a gun, so he almost said goodbye to you." ”

Councilor Wang raised his glass and said, "If you don't die in a great disaster, there will be a blessing in the future, come, drink a glass of wine to suppress the shock." ”

Pang Xiaonan also raised his glass, touched it with Councilor Wang, and said, "Accept your auspicious words, come, do it." ”

The two of them drank it all, and Councilor Wang asked with concern, "What's the matter? Don't you really need me to help you solve this killer?"

Pang Xiaonan took a handful of green vegetables and chewed it, shook his head and said, "No need, even if you help me solve this killer, will the person who hired him stop? The killer is not the root cause, I have to find a way to solve this guy who always troubles me." Besides, I'm telling you, I'm not afraid of gunmen now, at least not as embarrassed as I used to be. ”

"Really?" Councilor Wang also put a handful of green vegetables into his mouth, "You went to buy a gun? Even if you have a gun, if you want to practice marksmanship with 100 shots, there must be a process, and the master of marksmanship can be practiced overnight." ”

Pang Xiaonan sandwiched a piece of fried tofu into the bowl and said: "It's not to buy a gun, I have prepared a set of hidden weapons, although I am not very skilled in using a gun, but I still play with this hidden weapon quite well, next time I will try it, to see if his gun is fast, or my hidden weapon is powerful." ”

"Hidden weapon, you can't think of it!" Councilor Wang pointed at Pang Xiaonan, "No matter how good the hidden weapon is, it is not as powerful as the gun, do you think that it is still the era of cold weapons, and you can dominate the world with a hidden weapon?"

"Forget it, you don't understand it, you just understand that my secret weapon is similar to an ordinary pistol. Pang Xiaonan knew that he wouldn't believe it when he explained to Councilor Wang, so it was better to bury the suspense, "Eat vegetables and eat vegetables, this time the pot meat is really good." ”

"Anyway, be careful, there's really no way, I'll get rid of the mastermind behind the scenes, I don't want to watch you die young. "Councilor Wang is out of his heart and wants to help Pang Xiaonan.

"Look at what you said, you are frustrating, what did you die young, I am babaa!" Pang Xiaonan snorted a lot at the side before turning his face, "Don't worry, I can solve it, I can't bother your old man with everything." "Pang Xiaonan really doesn't want to find someone to help when he encounters something, because people can help for a while, but they can't help for a lifetime, even if something happens, it is fate.

The two no longer talked about the killer, and Councilor Wang brought Pang Xiaonan a good news, "I have a good idea here for the college student entrepreneurship project you said last time that the charity fund is looking for, and I specially called you over today, just for you to refer to it and see if it is feasible." ”

"Oh?" Pang Xiaonan was interested, raised his glass and toasted to Councilor Wang, and then respectfully poured a glass of wine and pushed it in front of Councilor Wang, "Tell me quickly, what a good project." ”

Councillor Wang cleared his throat and said, "That's right, two days ago, a young man came to me and said that he had a good idea and wanted to get my investment, so I asked him to meet and learn more about the project. This young man is a computer major, he has worked in a large network company before, the main position is product manager, that is, the Internet company is responsible for developing products, he now sees a trend, that is, big data, he thinks that the future development of the world will be based on big data, so he wants to develop an information product that uses big data to push messages. ”

Councilor Wang paused and scooped a bowl of soup, Pang Xiaonan was a little impatient, and said, "What is the specific product, you can say it quickly." ”

"What's the hurry, you wait for me to moisten my throat. Councilor Wang picked up the rice bowl and took a sip of soup, "His product is different from the previous mobile phone software, you look at the APP in our mobile phone, basically take the initiative to push some information to you, you look at the news on the homepage, basically the country's political news, his APP is different, he will use big data to analyze your preferences, and selectively push you the content you like." In other words, what searches you have had or what behaviors you have had on the Internet will be recorded by big data, and then the software will intelligently analyze your preferences and push the content you are interested in. ”

"Well, I get a little bit of it. Pang Xiaonan nodded, put away his attentive eyes, and took a piece of fried egg and ate it, "For example, I like to eat eggs, so the chef will always cook egg-related dishes for me, such as fried eggs, scrambled eggs, egg soup, steamed eggs, money eggs, etc." ”

"Yes, that's pretty much it. "Councillor Wang is pleased with Pang Xiaonan's ability to understand.

"But there will also be a problem here," Pang Xiaonan sandwiched another piece of fried egg, "Although I like to eat eggs, do I get bored of eating them every day?"

"I also thought of this, I asked him at the time," Councilor Wang also took a piece of fried egg and put it in his mouth, "people's interests will change, how can you ensure that this software will always be loved by people, like you said, you like to eat eggs, but this chef can only make eggs, then sooner or later you will get tired of it, you will fry this cook." The young man replied to me, saying that this software also has a mechanism, that is, while pushing the content you are interested in, it will also recommend some things that others love to see to you, to test whether you also like this content, if you click in, and read it, it means that you like this content, then this software will push this content related messages to you in the future, to ensure that you have a steady stream of fresh content of interest. ”

Pang Xiaonan thought about it for a long time, and finally understood the mystery, he pointed to the bowl of back pot meat, and said: " Isn't this what it means, originally I haven't eaten back to the pot meat, but the chef wanted to recommend this dish to me, so he scrambled eggs at the same time, but also fried a bowl of back pot meat, put it in front of me, he recommended me to try, so I sandwiched a piece of back to the pot meat to try, as a result, I found that this time the pot meat tasted good, I ate the whole bowl of back pot meat, so the chef knew that I also like to eat back pot meat, so in the future he not only gave me scrambled eggs, but also fried back pot meat for me. ”

"Well, that's a good explanation, that's the truth. Councilor Wang took a piece of back to the pot and chewed it with relish. "Today the chef added a bowl of back pot meat, and tomorrow he may add another bowl of this stuffed tofu to test your taste again, so although your interest has been changing, big data can control the change process of your interest, so as to respond to your interest in a timely manner and recommend the corresponding content to you. ”

"Well," Pang Xiaonan nodded, "It's indeed a good idea, is it difficult to implement?" He knows that many times ideas are ideas, and when it comes to really executing, there will still be many problems.

"The young man told me," Councilor Wang massaged his eyes, "It's not difficult to implement, he has mastered the technology of big data, the key is to constantly adjust the algorithm, I don't know exactly what the algorithm is, it may be equivalent to a chef making a dish, the proportion of seasonings in it or something, that is, the content recommended by the software, and the content you are interested in how high the correlation is, the more sophisticated the algorithm, the more accurate the push thing, it should be like this." ”

"You describe it very well, Lao Wang," Pang Xiaonan understood the meaning of the algorithm at once," It is worthy of being often with young people, worthy of being a genius investor, you understand this more deeply than me, the meaning of the algorithm you said should be what you described, that is, how much salt to put and how much monosodium glutamate, this dish can make me like to eat, that is, although I like the content he recommended, but to figure out how much I like it, why I like it a little more, that I like it a little less, and constantly optimize the algorithm, so that I don't want to like it. ”

"Yes, it is to poke at your pain points," Councilor Wang pointed at Pang Xiaonan's face with chopsticks, and then changed his words, "No, it should be to poke your laughter, poke your itch, make you feel cool, feel very cool!"

"Then what are you waiting for?" Pang Xiaonan raised his glass, "Such a good project, vote, don't hesitate!"
