Considering that human beings will live in the dungeon for nearly 2,000 years, in fact, the underground of Shangjing is now fully equipped, and in order to better produce oxygen, facilitate the circulation of gas and various nutrients, there is an agricultural cultivation land in the dungeon, but now it is no longer those farmers who are responsible for farming.

It was completely operated by robots, and along with Fang Xinya, Gu Bei happened to see those robots in charge of sowing.

"That's an artificial sun." Fang Xinya saw Gu Bei looking at a place where there was a bright bloom and introduced.

"The artificial sun has only been developed in recent years by the joint government research institute, and it also provides sunlight for the plants in the dungeon, which can actually be regarded as a nuclear fusion device."

In fact, why human beings have been pursuing controlled nuclear fusion, the most important thing is that controlled nuclear fusion will not be like nuclear fission, there will be no radiation, and controlled nuclear fusion is a clean energy source.

And mastering controlled nuclear fusion means that humanity will have an endless source of energy, and interstellar travel will become possible.

It's just that mankind does not know enough about controlled nuclear fusion at present, and it is only a preliminary fusion now.

"It's just that this thing is not very stable, it needs to be repaired regularly, and human food in the future is actually a problem, although there is a layer of farmland here, but after all, it can't provide the entire dungeon people." Fang Xinya sighed.

"Mr. Gu is an expert in astronautics, and the coalition government actually needs talents like Mr. Gu the most, by the way, Mr. Gu, why don't you go to the Navigator International Space Station? Many scientists from China have gone there. Fang Xinya turned her head, slightly puzzled.

After it was determined that the sun would expand, the status of the drama was drastically reduced, and for the continuation of human civilization, the outstanding scientists of the 21st century have gone to the Navigator International Space Station, and the headquarters of the United Government is also in the Navigator International Space Station.

"If everyone goes to the Navigator, what will happen to Earth?" Gu Bei smiled lightly, he couldn't say that after the system teleported him into this world, it directly teleported him to the Demon Capital.

"It is a blessing for mankind to have such a great scholar as Mr. Gu among mankind." Fang Xinya looked at Gu Bei with adoring eyes.

"It's everybody's job." Gu Bei is now lying and not making drafts, anyway, he will not have anything damaging to the world now.

"Hmm."

Huaxia Scientific Research Institute is located at the bottom of the dungeon, and after Fang Xinya showed his certificate, the soldier also led Gu Bei and his party into the elevator with a respectful face.

The depth of the Shangjing underground city is about 500 meters, and about 5 meters is the first floor, and the Huaxia Research Institute is located at the lowest level, with 75 floors underground.

Of course, at the bottom there are not only the Huaxia Research Institute, but also the Huaxia branch of the coalition government and the Huaxia detachment of the coalition government army.

All of the most core departments are located on the last floor of the earth.

Duoduo looked at the surrounding environment with a curious face, the scenery on the seventy-fifth floor is also very good, and the artificial sun is also applied on the seventy-fifth floor to provide light to the bottom layer.

"Why is there all electric light on it, and this layer uses artificial sun?"

"At present, artificial suns are too difficult to manufacture, so only a few key layers use artificial suns, and when the artificial sun technology matures, maybe all layers will use artificial suns." Fang Xinya said seriously.

"Mr. Gu, you also know that although we have been researching controlled nuclear fusion since the beginning of the 21st century, we can only use controlled nuclear fusion in planetary engines at present, and it is less used in other places, and there are still nuclear power plants in the entire underground city, that is, the ancient fission nuclear power plant." Fang Xinya sighed.

"Hmm."

The height of the lowest floor is not five meters, but ten meters high, and the Huaxia Research Institute is a building about three stories high, which has just touched the top.

"It's here, Mr. Gu, you can follow me in." Fang Xinya paused at the door for a moment, and then took Gu Bei into the scientific research institute together.

After entering the scientific research institute, Gu Bei felt that he had entered a place of future wind, at least much more advanced than the earth where he was originally located.

Gu Bei originally liked this kind of future world, but in fact, Gu Bei felt that it was a good choice to choose to go to the wandering earth to relax, in preparation for entering the Great Domination World.

Gu Bei felt that the later system would definitely allow him to enter those sci-fi worlds, otherwise he would say that entering the Wandering Earth was just a warm-up.

The Huaxia Research Institute is very large, and it can be said that most of the scientific research forces in China are concentrated here, and the professors and experts who originally belonged to the university are also here.

Originally, the Huaxia Research Institute was composed of the Huaxia Academy of Engineering, the Huaxia Academy of Social Sciences, the Huaxia Academy of Sciences, and some senior scientific research organizations in colleges and universities.

"Brother Gu." It was also at this moment that an old man walked out, and the old man looked happy, "I knew that Brother Gu would come." ”

"Academician Lin, Mr. Gu I have already brought it to you, so I will invite other scientists to come over?" Fang Xinya asked.

"Okay."

Gu Bei didn't know this old man, but it seemed that the old man knew him, and he didn't know what memories the system had arranged for those old men.

"Brother Lin, I haven't seen you for a long time." Gu Bei can only pretend, to be honest, after experiencing so many worlds, Gu Bei's acting skills are now stronger than those actors.

"Hahaha, I knew Brother Gu would come over." Academician Lin had a smile on his face, and he was very happy when he saw Gu Bei.

"What is this?" Academician Lin saw the flowers that were still looking around, and he was a little puzzled.

He had the impression that Gu Bei was not married.

"My daughter." Gu Bei smiled, and Academician Lin said with some surprise: "I didn't expect that Brother Gu, you have a daughter, and I would like to introduce my unsuccessful granddaughter to you." ”

"Grandpa, what did you say? When did I become unsuccessful? It was also at this time that an intellectual woman in a white scientific research uniform walked out.

The woman wears a pair of glasses, and although the dark glasses make the woman less beautiful, they are still beautiful.

"Brother Gu, let me introduce you, my granddaughter, Lin Na, what kind of biological research is she doing?" Academician Lin smiled, and before he could speak, Lin Na directly interrupted Academician Lin and said, "Gu Bei, a senior aerospace engineer, has participated in projects such as the Navigator International Space Station and planetary engines, and I have heard my grandfather say it many times. ”

Lin Na stretched out her hand again and said to Gu Bei: "Lin Na, who specializes in genetics, is now in charge of plant genetic research. ”

"Gu Bei." Gu Bei stretched out his hand and shook Lin Na, smiling faintly.

"Brother Gu, I asked you to come over this time because I had a task for you...... I wonder if Brother Gu is willing to take on the task? ”

"What task?"

"Small fusion engines."
