Yun Tianming told Cheng Xin three stories, this is Yun Tianming's last message to the human race, after which the Trimaran Fleet and Zhizi, the water droplet must leave and no longer contact with the human race.

When we meet again, we may be in the vast universe. The interpretation of Yun Tianming's intelligence soon began, but the human race has not discovered the real mystery.

Humanity has to carry out other plans, including the interstellar escape plan, but this is not feasible, because only one in 10,000 people of humanity can escape to the universe, and the rest will wait for death on Earth.

This is contrary to the values and moral norms of human society, and is likely to lead to violent upheaval and total social collapse, although this plan is still being carried out in secret.

The second plan is the long-distance evasion plan, which is to establish a human habitation in space far enough away from the solar system to avoid the eruption of the sun.

The third is the bunker plan, which uses Saturn, Jupiter, Uranus, and Neptune as shelters to build space cities on their shady sides to avoid the blows of the dark forest.

On the far side of the planet, the construction of a space city costs relatively little, and there is no need to leave the solar system and enter the vast universe, so that the planet becomes a shield to protect mankind.

The human bunker plan is going very well, and it is a feasible plan. On Pluto, Luo Ji presided over the construction of the Museum of Human Civilization, which was to prevent the destruction of human civilization from the attack of the dark forest.

The museum stores all the valuable cultural objects that have been preserved in the history of mankind, and the biggest difficulty is how to record the literature and history of mankind.

If you use paper to store it, it will deteriorate in about 50 years. Digital storage such as USB flash drives can only be maintained for about 200 years, and the data will be lost.

In the end, they found that they could only carve the words into the stone, which could be kept for about 100,000 years. Many people are interested in this museum of human civilization.

It's a huge project, and it's a huge project. Some people have visited it, and they have not gained anything, and they do not learn from history.

When developing the light-speed spacecraft, people discovered the metaphor of Yun Tianming, that is, it is not possible to use quantum working fluid to propel the engine, and only by using the curvature engine can the speed of light be traveled.

When human beings were defending the earth, on this day, they suddenly received an alert from the solar system, and countless information virtual screens bounced off.

The chaos in the city took only half a minute, the number of vehicles flying in the air suddenly increased, the traffic was extremely chaotic, and many vehicles that ignored the rules caused explosions one by one, which were out-of-control vehicles exploding.

At this time, everyone wanted to leave the Earth as soon as possible and fly to the base on the far side of Jupiter to avoid the impact of the light particles, even if the base was only half built.

Cheng Xin and Ai AA hurriedly ran to the company's spaceship, the Star Ring, but the launch pad was already overcrowded, and people crowded the port like locusts.

More than a dozen ships had already taken off and disappeared into the white clouds. The platform of the launch site is covered with the high temperature of the jets of the working fluid engines.

Even with coolant, such a number of spacecraft were launched at the same time, and there were more than the limits of the launch pad. At the time of re-filling the coolant. Ai AA took Cheng Xin with a rifle and hurriedly approached his spaceship in the water vapor.

Anyway, let's get on the ship first. Cheng Xin suddenly saw a female teacher with a group of elementary school students, waiting helplessly!

"Can we wait?" Cheng Xin asked.

Ai AA looked at the group of children and said, "You go, we have to line up to get on the boat, and there will be a while!" ”

The female teacher looked at Cheng Xin coming over, and hurriedly rushed over to grab her and said, "It's you, the sword bearer, this spaceship is yours, right?" Please, save the children! ”

The female teacher's hair was wet with the vapor of the coolant, but her face was red, which was burned. The children also surrounded and focused their eyes on Cheng Xin.

"We are from a space summer camp and could have gone to space in a synchronous orbit, but the alarm suddenly came, and they didn't let us board the plane and took someone else away!" The female teacher explained.

Cheng Xin said to Ai AA: "Take them with you!" ”520

This time, Cheng Xin gave up the decision to Ai AA to avoid making her own decisions, no matter what the result was, she remained in a morally perfect state.

Ai AA looked at Cheng Xin for a few seconds, and the meaning in his eyes was very clear: There are more people on the earth, how many can you save? If you make a decision for me, you won't save anyone!

But Cheng Xin just stared at Ai AA calmly, and finally Ai AA shook his head and said, "You can only bring three!" ”

The female teacher hurriedly said: "But this spaceship is a business plane, and it can seat more than a dozen!" ”

Ai AA said coldly: "The spaceship can only carry five people in the maximum acceleration state, and only at this speed can it escape, there are only five deep-sea positions, and the extra people will be pressed into meatloaf in the accelerated state!" ”

"Okay, then bring three! Better than nothing! The female teacher gritted her teeth and said, Ai AA looked at the children and said, "You are their teacher, you choose three!" ”

The female teacher let go of her clenched hand in a daze, and fell into fear and panic deeper than the sea, "Let me choose, how can I choose!" ”

Cheng Xin didn't dare to look at the children around him, the eyes of this group of children were like flames, like they wanted to scorch her, and finally Ai AA said: "Let me come!"

Her body showed a harder side than Cheng Xin, more like a human than Cheng Xin BC, Ai AA said: "Listen, classmates, now I have three questions, whoever answers correctly first will take whoever goes!"

Question 1, there is a light, turn off for one minute, flash it once, flash it again after half a minute, flash it again after another 15 seconds, so that after that, it will flash for half of each interval, how many times does it flash at two minutes? ”

"100 times!" There were children shouting.

Ai AA shook his head and said, "That's not right! ”

"1000 times!"

"That's not right!"

After a moment of silence, a weak girl's voice sounded: "Countless times! ”

Ai AA gave an affirmative look and said, "Okay, come here, think, now question 2, after a rope of uneven thickness is ignited from one end, it will take 15 hours to burn, how to use it to make a 15-minute timer?" ”

This time, the children did not rush to speak, but lowered their heads in thought, but soon a boy raised his hand: "Fold the rope in half and burn it from both ends!" ”

Ai AA nodded and said, "You come over too!" ”

That's the benefit of doing math Olympiad exercises! Cheng Xin sighed in his heart, this kind of Olympiad problem can be used as an additional score in BC to let children enter a better school.

But then due to the education reform, the Olympiad was abandoned, but now it has played a residual heat, which gives people a very absurd feeling, in order to survive, they have to do the Olympiad questions.

Ai AA said the last question: "82, 50, 26, what is the next number?" ”

One girl replied, "20! ”

Ai AA gave a thumbs up and said, "Come here!" With that, he and Cheng Xin took the three children and walked towards the spaceship without looking back.

Cheng Xin walked up the ladder and looked down at the launch pad for the last time, only to see the rest of the children, looking at them with the female teacher, like looking at the sun that will never rise again.

That desperate gaze made Cheng Xin's heart pierce her heart, and she had already experienced this feeling twice. Cheng Xin fastened the seat belts of the children together and let them enter the deep-sea cabin, and secretly swore in his heart that he would never abandon anyone again.
