Because Huang Chao was present, Old Man Brand was not good at pretending to be mysterious and explained the problem of gravity abnormality at the beginning. So Cooper knew that the strange sand and dust phenomenon he encountered was an incomprehensible existence that drove him here. Cooper felt that he had the responsibility to save the world.

Old Man Brand was still exposing Cooper: "You are our best astronaut, you trained for this many years ago. They brought you here." Cooper began to act intentionally, but he was unwilling to separate from his family: "How long will I go?"

The old man frowned: "It's hard to determine, how many years?" Cooper took a deep breath and said: "I still have children, professor." Rather than saying that he was rejecting the old man, he was hesitating. He felt sorry for the children. He promised his deceased wife to take care of the children. This was the father's responsibility.

Old Man Brand's face remained unchanged and said deeply: "Go to space and save them." His solemnity came from the heart. Cooper understood what he meant. If his children wanted to survive, someone must shed their sweat and time in space, and even buried their lives in the dark deep sky. This time Cooper was silent, and he had already felt his principles.

Huang Chao didn't say anything at this time. This was the difficult decision Cooper had to make. Their civilization was self-defeated to such difficulties, but Cooper showed his father's responsibility and responsibility at this moment, but he was still great and respectable. If everyone was a clever person and thought "I will definitely sacrifice anyway, but I will definitely not go", then no one would sacrifice at such a critical moment. Such people are completely the scum of civilization. When faced with choices, they would hide behind others with confidence. Looking back on history, they would think they were self-righteous and ridiculed the stupidity of their predecessors' sacrifices. If civilization was all this kind of scum, they would have no power to resist in the face of crisis.

Old Man Brand and Cooper are limited in their abilities. They cannot wave their hands to save the world. Without data, they cannot even solve the anti-gravity formula. But they try their best to continue civilization and sacrifice their own sacrifices for it. The remaining humans on Earth should feel glad that there is still such a great spirit among them. Cooper is just a mortal, but when he decides to step into the deep space, his mind is sublimated.

Human beings are complex. Even if Cooper regrets and resents in the future, it will not damage the glory of his body at this moment. Human beings can stand out from countless creatures and create a brilliant civilization because of the accumulation of glory from generation to generation. Huang Chao looked at Cooper and showed an encouraging smile. On the opposite side of him, when Old Brand saw Huang Chao's smile, he felt very happy and satisfied for some reason, as if his efforts and efforts were the most authoritative affirmation.

Huang Chao coughed: "If this is the case, I'm the only one." Old Man Brand was stunned for a moment and quickly replied: "Have you decided?"

Huang Chao nodded simply and said nothing touching. He had no responsibility for these people, so he was too lazy to show any touching attitude. Old Man Brand's eyes flashed with hesitation. He originally wanted to ask Cooper to go to his office and use a blackboard formula to increase Cooper's confidence, but now he dare not take Cooper and Yero with him.

He turned out to be bullying Cooper and didn't understand it. When an outsider reads a blackboard calculation, he will only think that the anti-gravity formula is complicated and profound. However, those who are familiar with Huang Chao will try to solve it themselves after having a idea. After all, solving it can save humanity, and no one will be polite to Old Man Brand at this time. Like Mann before, he understood that this formula could not be solved at all, which led to his complete despair.

Huang Chao listened to the introduction of the situation by the scholars of the SA in the conference room, mainly to Cooper about Saturn's wormhole and the space behind the wormhole. Huang Chao did not want to pour cold water on these people, so he kept a polite smile and nodded from time to time, making the narrator feel Huang Chao's "serious response". In fact, Huang Chao was speechless about the world, and a wormhole appeared at the door of his home, a wormhole that could steadily cross space! They have been exploring this result in civilization destruction.

These people from the Space Administration did not know Huang Chao's secret complaints. Most of them participated in the expedition to save humanity. They were excited and full of dedication that made Huang Chao admire and amused. Cooper is now seriously considering this issue. After a black scholar finished explaining, he asked Old Man Brand about his doubts: "Professor, if we can find a suitable planet, then what can we do to save humans on Earth?"

Everyone smiled at Cooper. Cooper's questions showed his attitude of joining. Now everyone regards him as their own. Old Man Brand showed a confident smile and looked at Huang Chao calmly: "We have two plans, Plan A and Plan B, come with me."

He led Cooper and Huang Chao to the external construction site again, and Old Man Brand showed a mysterious smile: "Look at this building, what do you think it looks like?" Cooper, as a professional astronaut, had an IQ online. He turned his head and quickly saw the mystery: "The entire building here is a huge centrifugal device?"

Old Man Brand nodded with a smile, Huang Chao said, "So you have to launch the entire building into space as a large space station?" Cooper also realized that it was unreasonable here. How could such a heavy object happen to space? In the past, humans built small space stations and had to be continuously launched and organized to allow it to be assembled in space.

"Since I discovered the gravity anomaly, I have the idea that using gravity to travel interstellarly is feasible. I have proposed a hypothesis that as long as it is perfected, it can be lifted off to a large space station."

Cooper said a little unhappy: "You want us to bet on your possible completion at the cost of everything we have? What is that hypothesis?" Cooper of course understood that this was the key to the problem, and Old Man Brand was also helpless. As long as he introduced it here, Cooper and Huang Chao would definitely understand its importance.

Brand said: "When you come back, I will definitely fulfill it. This is my promise." The old man looked determined and had a solemnity of dying for it the next moment, which shocked Cooper. What comforted the old man was that Huang Chao, who was most worried, had no reaction.

“So what is Plan B?”

As an expert in biology, Miss Brand took over the introduction of the responsibility. She brought the others to the biological laboratory and pressed the button on the refrigerated biological sample cabinet. With the sound of jets, a sample bucket carrying a sample of human fertilized eggs popped out. Miss Brand smiled and said, "Plan B, Super Population Bomb."

This plan is to bring these fertilized eggs to a habitable planet, use biochemical means to reproduce, and become a continuation of human civilization. There are many fertilized eggs, and try to maintain human diversity as much as possible: this is a compromise method that has too low transportation power and cannot transport a large number of "living people" and has to be used.
