"Big brother, what the hell does my dad mean by that?" Cheng Huaimo touched his head, looking puzzled. Pen & Fun & Pavilion www.biquge.info

"I think your father agreed to let you go to military school." Zhang Nan guessed with a confused face.

"But why does my dad look so happy, it's not his character." Cheng Huaimo still asked stupidly.

"I guess your father is happy to see you grow up so fast, but you have to listen to your father's words, train hard, you look at the competition just now, your father used a trick to kill you, this is you going to the battlefield, isn't it sent to death?" Zhang Nan remembered the powerful momentum that erupted from Cheng Biting Jin's body just now, and he couldn't breathe, so that Cheng Huaimo couldn't move, it was really powerful.

I haven't seen blood before, I haven't been on the battlefield, I can tell it at once.

"Well, big brother, I know, I'll work hard, thank you." Cheng Huaimo said with a smile.

"It's not me who you want to thank, it's your father, what are you doing in a daze, and you don't go home with your father." Zhang Nan smiled, picked up the camouflage uniform thrown on the ground, and handed it to Cheng Huaimo, Cheng Huaimo took it, smiled and thanked him, and chased him out.

Not long after sending Cheng Huaimo out, Su Wen came over to report again.

"Master, Lord Wei Tianwu of the Ministry of Industry is here to visit, this is a famous post." After Su Wen finished speaking, he handed the name card to Zhang Nan.

Zhang Nan took the name card and said, "Please come in quickly, just wait for me in the hall." After Zhang Nan finished speaking, Su Wen turned around and walked to the gate, while Zhang Nan started a dialogue with the system.

"System, is there any design for this blast furnace ironmaking?" Zhang Nan asked.

"Yes, given that there is no epoch-making technology for the host search item, the blueprint only costs 10,000 points." The system said without the slightest emotion.

"Ahem, how much do you say?" Zhang Nan suspected that there was something wrong with his ears, and the design of a blast furnace ironmaking actually cost 10,000 points, and it was without the emergence of epoch-making technology.

"If the host can't afford to pay the points, the system intelligently recommends the method of shaft furnace ironmaking in the Ming Dynasty, the principle remains the same, but the price is low, given that the host is currently in an era that is easy to build." The system says.

"Then how many points does this shaft furnace ironmaking method cost?" Zhang Nan asked cautiously.

"This method only requires 4,000 points, and a 100-to-1 model is sent to the host, which is convenient for the host to build." The system said intimately.

"Okay, okay, that's it, I'm going to redeem it, isn't it just 4,000 points, it's a small problem, but you have to write this design so that the people of the Tang Dynasty can understand it, and the place where the translation should be translated must be in place." After Zhang Nan finished speaking, he saw that his account was missing four thousand points, and the distressed Zhang Nan twitched, this is really not an overnight thing, first of all, the points in all aspects are a big problem.

"After the redemption, the design drawings and model hosts can extract them by themselves." After the system finished speaking, Zhang Nan hurriedly walked to the front hall.

Wei Tianwu sat in Zhang Nan's front hall, looking at the various objects in Zhang Nan's front hall, many unheard of things, and suddenly a small thing attracted Wei Tianwu's attention, even the tea that Su Wen served himself, Wei Tianwu forgot to drink it.

"This is just a small toy, if Master Wei likes it, you can take it." Zhang Nan suddenly screamed, startling Wei Tianwu.

"Eh, Lord Zhang, you're scared me to death, but what did Lord Zhang say, this is a small toy?" Wei Tianwu pointed to the Rubik's Cube placed on the table.

"Yes, that's right, it's just a toy, Master Wei can try it himself, this thing can be turned." Zhang Nan raised his hand and signaled that Wei Tianwu could try it himself.

Wei Tianwu is not polite, he picked up the Rubik's Cube and turned up, although Wei Tianwu is the secretary of the Ministry of Industry, but he has no resistance to these things with a sense of science and technology, some people like money, some people like power, some people like beauty, Wei Tianwu is no exception, but Wei Tianwu likes freshness, or he likes technology.

Wei Tianwu turned the Rubik's Cube and asked, "Lord Zhang, is this toy going to match each of these colors together?" "I have to say that Wei Tianwu's observation is still very powerful.

"Yes, that's right, but when you spell out one side and then fight the other side, the first side will be disrupted, so how to fight the second side without disrupting the front is the essence of this toy." Zhang Nan said with a smile.

After listening to Zhang Nan's introduction, Wei Tianwu began to think, but no matter how Wei Tianwu turned, he couldn't even spell out the first side. Wei Tianwu smiled and put down the Rubik's Cube in his hand.

"The adults in the court all said that although Lord Zhang was not in the court, his influence was not small at all, and he could even change the emperor's mind. Wei Tianwu said with a smile.

"Eh, Master Wei can't say that, I'm just a small person, as for changing the emperor's mind, it's absolutely unacceptable." Zhang Nan reminded.

"Ah, yes, in the next moment, don't be surprised." Wei Tianwu also knew that what he said was a bit too much, so he hurriedly said.

"It's okay, it's okay, Master Wei just remember not to say it again in the future." Zhang Nan said.

"By the way, I came to visit Lord Zhang today for what Lord Zhang said in the court that day." Wei Tianwu said with a smile. "On that day, Lord Zhang made a bold statement in the court, saying that there is a new iron-making method, which can increase the iron output of my Datang to 150,000 tons, which is really proud, so today I will come to ask this Lord Zhang for the emerging iron-making method." Wei Tianwu is now familiar with the tonnage system proposed by Zhang Nan that day.

"Master Wei doesn't think these words are making a big fuss." Zhang Nan made a joke, after all, this has increased the steel output so much, and it is not very convincing.

"To be honest, I just thought that what Mr. Zhang said could not be realized, but after seeing Mr. Zhang's toys, I believed it a little." Wei Tianwu said with a smile.

"This is not nonsense, it is not a secret, the drawings of this new iron-making method have been drawn below, and a model has been made that is a hundred times smaller." Zhang Nan said confidently.

"Oh? Mr. Zhang has such a ability, which really impresses him, I wonder if the drawings can be borrowed from the next view? "Wei Tianwu said.

"Naturally, Lord Wei, please." After Zhang Nan finished speaking, he exchanged the drawings of the shaft furnace ironmaking method from the system and handed it to Wei Tianwu.
