April, Guangzhou, Baiyun Airport.

Ning Qi dragged the suitcase to the exit of the station, and saw Tao Donglai in the crowd waving his hands high at him with an excited face. A smile appeared on the corner of Ning Qi's mouth, and he also raised his hand to signal to the other party.

"Old classmate, I've waited for you!" Tao Donglai grabbed Ning Qi's hand, and the enthusiasm made Ning Qi feel as if he had returned to his college days ten years ago.

Ning Qi and Tao Donglai are classmates in college, and they are roommates in the same dormitory, and their relationship in the four years of college is so strong that they can wear a pair of pants. But after graduating from university, Tao Donglai actually went to join the army as a soldier for three years, and then went south to start a business and engage in real estate, and became his own boss, while Ning Qi chose to stay in school and become a teacher while studying for a doctorate as a senior intellectual. However, in recent years, Tao Donglai's business has become bigger and bigger, and his pocket has also swelled, so he took the initiative to hold a class reunion in Guangzhou every two years, eating, drinking and having fun.

The relationship between the two is good, but Tao Donglai, a busy man, will personally go to the airport to pick him up today, which Ning Qi did not expect, I remember that when I came to Guangzhou a few times ago, Tao Donglai couldn't get out because of work reasons, and only arranged for clerks such as secretaries to pick up the airport at the airport. This small detail did not attract Ning Qi's attention at first, and when he got out of the airport and got in the car, Tao Donglai did not take a full-time driver as before, but sat in the driver's seat by himself, and Ning Qi found that today seemed to be really unusual.

"Did your driver and secretary negotiate a strike together today?" asked Ning Qi jokingly as he fastened his seatbelt.

"Not really, because there are some things I want to talk to you about alone, and I don't want outsiders to be there. The look on Tao Donglai's face was not a joke.

Ning Qi nodded and didn't ask any further. As a friend for many years, he knows Tao Donglai's character very well, and if Tao Dong says that something "needs to be discussed", then it means that this matter is by no means a trivial matter.

After being silent for a long time, Ning Qi spoke: "So the reason why you called me over this time shouldn't be what you said on the phone, in order to prepare for this year's class reunion, right?"

"I don't have time for a class reunion this year, and I have too many things to do in the second half of the year. Tao Donglai did not deny the little tricks he played, he looked sideways at Ning Qi's face and was not unhappy, and then continued: "Maybe you will be busy with me in the second half of the year." ”

"Are you planning to poach me to work in your company?" Ning Qi smiled dumbly and said, "Although we majored in business administration in college, you should know that my interests are different from yours, and I really don't know anything about doing business in the sea." ”

"Of course I know that you are not interested in doing business, you pseudo-Ming fan, you are interested in studying history! Don't worry, I will let you fly all the way to Guangzhou, and I will not force you to do things that you are not interested in. ”

Ning Qi's eyes lit up: "Did you buy something good at the auction, or did your real estate company repair the house and dig up the ancient tomb?"

At this time, Tao Donglai sold Guanzi, avoided answering this, and instead asked about Ningqi's recent situation. Although Ning Qi was a little helpless, he thought about it anyway, Tao Donglai should have something to ask for himself, and it was impossible to hide it all the time.

Tao Donglai has already helped Ning Qi book a room at the Four Seasons Hotel in Guangzhou, and after the two of them arrived, they went through the formalities and entered the room, Ning Qi sat on the sofa and said impatiently: "Okay, what the hell, you can quickly recruit from the truth!"

Tao Donglai didn't rush to speak, took out a cigarette case from his handbag, smoked one and handed it to Ning Qi, Ning Qi shook his hand and said, "Quit it." （.）”

"I haven't started a family again, why do you quit smoking in a good way......" Tao Donglai muttered, took it back and lit it himself, and took two puffs before continuing: "Ning Qi, I asked you to come to Guangzhou, because there are some things I want you to see with your own eyes." But I want you to make a promise to me, no matter what you think after seeing it, you will never tell me what you see or hear, no one can do it!"

"To put it so strictly, you can't have done something illegal, right?" asked Ning Qi with a suspicious expression.

"Look at your courage, it's the same as when you were studying before, you haven't grown at all for so many years!" Tao Dong came to see Ning Qi and didn't talk, so he had to respond: "Don't worry, it's not a crime." But this matter is really not suitable for publicity, and you will understand it naturally after you read it. ”

"When will you see it?" Ning Qi saw that Tao Donglai was so secretive, but it aroused his curiosity even more.

"Don't worry, I'll take you there tonight. Tao Donglai stood up and said, "Okay, you rest for a while, I'll pick you up for dinner later, and introduce a few friends to you by the way." ”

"You're going to team up for the rhythm of the next dungeon!" Ning Qi couldn't help but joke.

Tao Dong, who had already walked to the door, turned his head and smiled: "You're right, it's to go to the next copy." ”

At dinnertime, Tao Dong came to the room to pick up Ning Qi, and took the elevator directly to Yu Yue Xuan on the 71st floor of the hotel. Tao Donglai beckoned Ning Qi to sit down next to him, and at the same time introduced several people to each other's identities.

The flat-headed and black-skinned strong man sitting on the right side of Tao Donglai is called Yan Chujie, a native of Inner Mongolia, Tao Donglai was a comrade-in-arms of a class when he was a soldier, and he only transferred to the local area the year before last, and now he is the director of the security department of a large state-owned factory, and he doesn't talk much and looks very stable.

The man next to Yan Chujie with black-framed glasses and a white and pure image of a literary and artistic young man is called Bai Kesi, which sounds a bit like a foreigner at first glance. Bai Kesi and Tao Donglai are said to have had a business cooperation for many years, running a small metal processing factory and a furniture factory, and also doing foreign trade import and export agency business. This guy also has the identity of an online writer, which made Ning Qi slightly surprised, and he really didn't understand where he had the energy to write novels to entertain the public in addition to taking care of his business.

The last man sitting between Bai Kesi and Ning Qi looked younger, but Ning Qi had seen it, it was Tao Donglai's cousin Gu Kai. When Ning Qi went to Tao Donglai's hometown to play, this Gu Kai was still in junior high school at that time, and he was already in his thirties in a blink of an eye. Tao Donglai introduced that Gu Kai went to the United States to study at university, and after graduation, he stayed there to develop, and is currently working as a lawyer in San Francisco.

"Everyone is here, let's serve!" Tao Donglai waved his hand and motioned for the waiter to open the table.

A few people chatted while eating, and Ning Qi noticed that Tao Donglai didn't order wine, and the other people didn't seem to have any objections to this. From the conversation, it was clear that these people had met more than once before, but the topic they talked about did not mention what Tao Donglai said in the afternoon.

After the five flavors of the dish, Bai Kesi asked Ning Qi: "Mr. Ning, I heard that Boss Tao said that you like to study history in your spare time, according to your opinion, if a person travels to the ancient times hundreds of years ago, what kind of skills do you need most to get ahead?"

Ning Qi felt a little strange at first, and then he was relieved when he thought of the other party's identity as an online writer. Out of politeness, Ning Qi still replied seriously: "With all due respect, if a modern person travels back a few hundred years, the chance of getting ahead is very small. In fact, the professional skills and knowledge mastered by modern people could not be used much in ancient times, and it is more likely that they will be regarded as neurotic because of their whimsical words, or they will be slowly assimilated by the society at that time. I don't think I would have been able to survive for a month if I didn't have more practical survival skills. ”

"That's not necessarily!" It was not Bai Kesi who raised the objection, but Yan Chujie, who had never spoken much: "I have been in the army for more than 10 years, and I have personally led thousands of soldiers, and every day in addition to eating and sleeping is to study military affairs, and in terms of the ability to lead troops to fight, how can I be better than the ancients who had limited knowledge hundreds of years ago, right? If I had gone a few hundred years ago, it would have been no problem to be a general or even a general soldier." When the time comes, I will train a strong army to come out, and I can fight all over the world just by lining up and shooting tactics. ”

"Mr. Yan, I believe in your military qualities very much, but if you were put hundreds of years ago, it would not be so easy to train a strong army. Let's not talk about anything else, let's just say that people at that time could only eat two meals a day, and this body could not adapt to the exercise of a large amount of exercise, and to solve the problem of eating, you had to solve the logistics supply first, and the consequence of forcibly training troops without enough food was likely to be mutiny. In addition, the supply of ordnance is also a major problem, in order to achieve an overwhelming advantage over the army that uses cold weapons, we all know that firearms must be used, I believe you are very familiar with firearms, but do you know how to manufacture firearms yourself? Even if you understand the principles of firearms manufacturing, it requires metallurgy, metal processing, and chemical technology supporting industries to be very perfect. The strength of the army is the embodiment of national strength, and it is unlikely that it will support a modern army at the level of productivity of hundreds of years ago. Ning Qi talked about it and couldn't help but crack and retort to Yan Chujie.

Yan Chujie wanted to say a few words when he heard this, but Bai Kesi took the lead: "What does Mr. Naning think can be done to ensure that modern people can have a relatively safe foundation for development when they return to ancient times, and then use their knowledge to change the society at that time?"

"At least...... The modern industrial system must be established in the shortest possible time, and only a great leap forward in the productive forces can change society. This time, Ning Qi pondered for a while before answering, but then shook his head again and denied his statement: " This assumption is unlikely to be done, a person's knowledge is limited, and it is impossible to build an industrial system alone, not to mention that modern industry must also have the guarantee of electricity, and the traveler may become the Faraday of that time and space by virtue of his own knowledge beyond the times, but even if it is as great as Faraday, from the discovery of electromagnetic induction to the construction of the world's first power plant, it took a full forty-four years, even if we can shorten this time to half, it is also unacceptable. Of course, if you really believe that the crude hydraulic machinery in the novel can drill the rifle and even mass-produce munitions, then I have nothing to say. ”

Tao Donglai summed up Ning Qi's speech in a timely manner: "In other words, it is basically impossible to have the power to change society in ancient times single-handedly, right?"

Ning Qi nodded and said, "Unless you dress as an emperor directly, you have to revolve around your ass all day." Either you have to bring a large technical support team with you, as well as enough materials to ensure that you can run smoothly in the initial stage. ”

After Ning Qi finished speaking, he noticed that the other four people silently exchanged glances, as if they had reached some kind of tacit understanding in silence. Then the topic turned to their respective private lives, Ning Qi was surprised to find that the five people present were all bachelors, Yan Chujie and Ning Qi themselves are middle-aged men who have not yet married, and Tao Donglai and Bai Kesi have each been divorced once, Gu Kai has an American girlfriend with a stable relationship, but the elders in the family seem to disagree with his plan to find a Yanma as a wife. But why Tao Donglai summoned such a few people from all over the world to meet here, so far Ningqi still has no clue.

After the meal, the other three said goodbye and left, while Tao Donglai accompanied Ning Qi back to the room, and Ning Qi found that there was an extra travel bag on the **.

"I asked someone to send it, and the environment is not too convenient for the place we are going to, there are shoes and clothes in the bag, you change first." I've got some business to attend to, and I'll pick you up at twelve o'clock. Tao Dong finished speaking, and left without waiting for Ning Qi to ask more.

Ning Qi opened the travel bag and saw that it was a set of BIA's assault suit and hiking shoes, and couldn't help but be a little puzzled: "Do you have to go climbing the mountain in the middle of the night?"

Ning Qi waited until twelve o'clock with a problem, Tao Donglai really came on time, and also changed into a full set of outdoor outfits, Ning Qi only brought his mobile phone and room card and set off with Tao Donglai. When he arrived at the parking lot, Ning Qi found that the three guys who were having dinner together today were already waiting in a Grand Cherokee, and they also changed their lines, and it seemed that they had already made arrangements. Although there were some doubts in his heart, but once he came, he was safe, and Ning Qi would definitely not be able to retreat at this time, so he got in the car and didn't ask anything more.

Ning Qi has been to Guangzhou many times, so he can still distinguish the direction in the dark night, and when he saw that the car actually drove all the way to Yuexiu Mountain, he really responded to his previous guess. But there are only some cultural landscapes in this Yuexiu Mountain, what is there to see when you go up the mountain in the middle of the night?

The car stopped outside the Yuexiu Mountain Stadium, and after getting out of the car, Yan Chujie, who was tall and tall, took out a large mountaineering bag from the trunk and carried it on his back, and then several people walked up the mountain.

When passing by Zhenhai Tower, Tao Donglai asked out loud: "Ning Qi, do you remember this place?"

Ning Qi responded: "Of course I remember, when I first came to Guangzhou to play, you knew that I liked Ming History, so I specially brought me here to see it." ”

Zhenhai Tower is one of the landmark buildings of Guangzhou, was built in the Hongwu period of the Ming Dynasty, has experienced many times of damage and reconstruction in history, the current Zhenhai Tower was rebuilt in 1929, this five-storey ancient building is not only a famous cultural landscape, but also the location of the Guangzhou Museum.

After going around Zhenhai Tower, the team walked a few hundred meters under the leadership of Tao Donglai into a dense forest with no road. Tao Donglai had already prepared, the strong flashlight shone on the ground, and several people walked in the bushes for another two minutes, already far away from the mountain trail, before Tao Donglai signaled the team to stop. Yan Chujie opened the mountaineering bag and took out the things inside and began to spread them on the ground, Tao Donglai stuffed the flashlight into Ning Qi's hand, and squatted down with Bai Kesi and Gu Kai to help, Ning Qi took a look at it by the light of the flashlight, and found that it was actually a small tent, could it be that these people still plan to camp on Yuexiu Mountain?

The tent was quickly set up, and under the leadership of Tao Donglai, all five people entered the tent, and Yan Chujie took out an LED tent light from his bag and hung it up to connect the power. Ning Qi found that the faces of the other people were very strict, and there was no relaxed atmosphere of wild camping at all.

Tao Donglai lowered his voice and said to Ning Qi: "From now on, no matter what you see, please stay calm, don't speak loudly, don't use a flashlight to shine everywhere, and listen to my command when you act, is there a problem?"

Ning Qi didn't know what to say anymore, so he just nodded blankly.

Tao Donglai slowly took out a black rectangular object from his personal pocket, which looked like a mobile phone at first glance, slightly narrower than Ning Qi's own iPhone5S, Tao Donglai pressed it, and a green light lit up on the surface of the thing, and then expanded at a rapid speed, covering all five people in the tent.

Ning Qi only felt that when the green light flickered in front of him, his brain suddenly felt dizzy, and he couldn't help but exclaim, "What is this!"

"This is a door that God has opened for us!"
