"The beginning of the war was abrupt, and the end was obvious. Earth, the first home planet of mankind, was destroyed, and countries of all sizes either went extinct or drove spaceships away from Earth to a new viable planet that had been pre-founded. Our Federation was founded during a long interstellar journey - a union of nations large and small. With an incomprehensible sigh, the blind man made a concluding remark.

Zhao Zhuo tilted his head and thought about things, and after the blind man finished saying this, he opened his mouth and followed his train of thought: "Then...... Humanity began to settle on the second planet, and at the same time began to continue to look for a planet where they could live, because there were more ways to survive, so the fear of nuclear weapons became less and less, and the use of nuclear weapons became more and more unscrupulous. Under the situation of scientific and technological development, human beings have abandoned their homes again and again, destroying the planets in the universe that can survive like locusts? ”

The two old men nodded, as if they felt a little embarrassed to be called "locusts", but they couldn't refute it. The blind man smiled even more and asked the lame man: "How many of our earth are ruined by the Federation?" Seventh or eighth? ”

"How do I know, anyway, it's definitely going to be five." Glaring angrily, Chen replied.

Zhao Zhuo grew his mouth in shock: "Five? Are you saying that our Federation has already ruined five Earth-like planets in a row after destroying the first home planet, Earth? ”

"I'm embarrassed to admit it, but that's pretty much it, there must be more than five of them."

"What a bunch of bastards! If you are full and have nothing to do, since there are so many planets, why not just stay and let us live for ourselves! When the time comes, everyone will live on one planet, how comfortable will it be? Why do you have to stay in such a crowded slum to survive now! The young man, who was unusually sensitive to the living area, slapped the table heavily and cursed through gritted teeth.

Chen Cripple looked at the blind man, and now the other party was also looking at him with "hollow" eyes at this time, so he just sighed and explained: "If there are two houses now, one is in tatters and may collapse at any time, and the other is new, bright and bright enough to last for one hundred and eighty years, and let you move, which one do you choose?" ”

The boy was stunned and fell silent.

"The Federation has been committed to Star Technology for so many years. In the shortest possible time of interstellar travel. But even then, the distance between two adjacent Earth-like planets is extremely far. The time required for a single relocation is also more than 100 years. Therefore, when human beings create a new planet with intact environmental resources, it will naturally produce the kind of contrast I just mentioned. Of course, some people in the Federation have mentioned the possibility of letting some people stay and relocate others, but the question is - who to keep and who to take away? No one wants to let go of their good life, but instead shrink back to live their own hard life. How many people would willingly choose the former between a destroyed planet that has lost much vitality and a brand new planet that is full of vitality? Chen lame paused one by one, and asked everyone in the room word by word.

After a short silence, the blind man continued: "In the history of the Federation, in fact, there has never been such an attempt - they once abandoned some war criminals and criminals on a certain abandoned planet, trying to let the human beings on Earth branch out in the universe, but the events of the afterlife completely cut off this idea of the Federation. ”

Zhao Zhuo raised his head, looked at the blind old man, and silently asked about the outcome of that matter.

"In the thirtieth year of interstellar travel of the Federation, there has been no news from that planet. This means that the planet has become a death star. ”

The old man shook his head with a wry smile and continued: "Since there is such a failure, there are even fewer people who are willing to stay on the old planet and develop slowly. Humanity can only destroy one planet, move another, destroy another, and move another...... The cycle repeats itself. As long as there are other planets for humanity to live on, then this process will continue. But what if one day we can't find such a planet again, or if we encounter a catastrophe in the middle of an interstellar journey and everyone dies in the stars? If you continue to move like this, there will be problems one day. And that kind of problem would mean the complete destruction of humanity. ”

"It's better for such locusts to die." The young man, who was listening quietly, lowered his voice and said angrily. Both old men heard it and smiled with complicated expressions.

"Nobody wants to be a locust. Even if we have become locusts, we are trying to change ourselves back. As he spoke, the blind man straightened up, groped for his glass, dipped his fingers in some undried wine stains and began to draw on the coffee table. He was blind, but he seemed to be very familiar with the coffee table, and his mind was very clear, so the things he drew were no different from normal people.

When Zhao Zhuo looked down, the old man was painting a tree.

"This is the Federation's tech tree. The core is the ultimate above this branch, which is the fruit. "The old man drew a circle on a branch of the tree that represented the fruit, and wrote the word "core".

"Star Technology is this branch, and it has not yet reached the end, and there is no way to see the fruit. But we can also roughly guess that it is something similar to space travel. Pointing to another, slightly smaller branch, the old man continued.

"Although the kernel fruit is delicious, if you eat it too much, it will poison people. So as tempting as it is, we have to find a way to give it up now! Otherwise, sooner or later, it will kill you. Pointing to the fruit that represented the core, the old man said, then stretched out his finger and pointed at the rest of the tech tree: "Although there is no such branch, there are other branches on our tech tree, since this path is not working, we should find another way out." Maybe the fruit from other branches will be non-toxic and safe. ”

"Therefore, if human beings want to get rid of the influence of nuclear weapons, they must vigorously develop other technologies and find new alternative products. We need to rebuild the tech tree! ”

The knuckles of his fingers gently tapped on the glass coffee table, and the old man's face showed a rare look of sternness: "And as a scientific researcher who promotes the development of the science and technology tree, it is the top priority!" ”

"Now, you should understand how great the influence of a genius like Li Xiudao must have on the Federation." Looking at Zhao Zhuo, the blind man said.
