"... did someone put forward in the meeting and want to go back and have a look?" Lin Xuanxuan leaned against Zhang Yuan and watched TV. She suddenly asked.

"Go back? What are you doing back? "

"Hasn't anyone proposed it? There should be many first generation people in the meeting. "

Zhang Yuan thought for a moment and said: "... It seems that there is no need in this regard. After all, it takes time to fly back. Even if we have warp speed, it will take 800 to 1000 years... As for what happened to homologous humans, I think, alas, I can't control too much. We even told them the clue of how to use curvature Technology... It's worth a little amoeba points anyway? "

"Social progress is not just scientific and technological progress. If there are difficulties, they should be overcome by themselves."

"If you really become a degenerate civilization, you may be eaten by virtual world technology... There is no need to go back..."

Lin Xuanxuan was silent for a while. The virtual world technology originally given to homologous human beings is a very big double-edged sword! They may be greatly developed or harmed by it, and fall into the same dilemma as the "human branch of the bright galaxy".

She can only secretly wish the distant earth civilization and other branches good luck.

……

A month later, the two had logged onto the top of the largest Titan class "departure" spacecraft and found their own residence.

In this large flying saucer like spaceship, the living environment is very complex, like a big maze. However, with the help of the auxiliary brain, there is no big problem in remembering these functional areas. It is precisely because of this complex three-dimensional structure that it can accommodate the daily life of 50 million people.

Before everyone officially began hibernation, a group of old friends got together and had the last drink.

Recalling the hard journey along the way, we can't help but sigh. When the earth times spent 3000 years drifting to its destination, who would know that one day in the future, mankind can become a real four-level civilization?

The 3000 year journey at that time, now, only... 10 years!

"It's really something you can't even think of."

Li Zhendong, who likes to pretend to be forced, first began to show off his credit. Their team invented the fuzzy signal that can be used on the way of superluminal speed, which is very important when sailing in curvature.

"All the small ships will be attached to the big ship and taken away together. And the six large spaceships will be lined up in a slash... "

"Slash, you know."

"Our departure Titan class will be in the front row and issue orders to the spacecraft obliquely behind, stop, accelerate, slow down, obstacles in front, etc."

"Due to the existence of light barrier, the rear spacecraft can only receive the instructions of the front spacecraft, but there is no way to send instructions to the front spacecraft, which is quite unilateral communication."

"Therefore, if there is something urgent in the rear, the spacecraft can accelerate to surpass the front, and then send a signal. Because of this, the whole fleet will not fly at the maximum speed. It will only be 2.5 times the speed of light at most. "

"Hard work, very good plan!" Zhang Yuan deeply knows that this work is very valuable, so Li Zhendong's forcing is not unreasonable.

"Here's to you!"

With a bang, they touched the cup.

Suddenly, several scientists studying subatomic are a little upset. You Li Zhendong just made a communication. Curvature technology is the big head!

Although now it is only three times the speed of light, and the planetary large curvature has not been conquered, the credit can not be denied!

Zhang Yuanlian hurriedly said, "here's to you too!"

Zhao Qingfeng shook his head and shrugged his nose there. Quark energy room is also very important. Without the huge energy support of this thing, curvature is a fart! They didn't make quark energy?

"Here's to you!"

Several experts in the virtual world are not very satisfied. Even Ichiro Yamamoto's dead house is rolling his eyes there. If there were no virtual world technology, you people would have died for thousands of years. Why don't you boast here?

There's no ashes left!

Throw it into the stars!

Zhang Yuan suddenly understood... These people are uniting to fool him!

Because Lao Zhang's fame is so popular that he has crushed more than one scientist, and even passed his fame to another civilization!

Recently, the communication with the TOS civilization is based on curvature spacecraft, and electromagnetic waves are no longer used.

In the words of the TOS, they are almost grateful to Zhang Yuan. Half of the space is praising and lamenting "optical perception", and then praising Zhang Yuan. It's best to abduct Zhang Yuan. It would be better if Zhang Yuan could join the TOS civilization!

Half the space is business

So these guys are a little upset.

"You or me!" Thinking of this, Zhang Yuan patted the table very impolitely.

Everyone laughed.

Speaking of the old friend of the TOS civilization, it's a pity that we can't act together. But there are countless possibilities in the future. There is always a time to meet.

A scientist suddenly sighed: "in fact, every civilization is very difficult... We humans have had turbulence in these hundreds of years. But who knows what difficulties the TOS civilization has experienced in these tens of thousands of years? "

"Without eyes, perhaps from the practical level, they are more difficult than we thought."

"Yes." Zhang Yuan nodded in agreement.

"Now that we have gone through all kinds of hardships, we are already a fourth level civilization. How should we reach the fifth level civilization?"

"So far, there is still no good way... I can only taste it there." Zhang Yuan shook his head. "We still lack a lot. First of all, have you seen a four-level civilization with an average life span of 600 or 700 years?"

"Low is a little pathetic?! The fourth level civilization has developed well in the Milky way at least. It can only live for 600 or 700 years. Shame, shame! "

Now scientists have tried their best to raise the average life span of human beings to 700 years, but this life span is still a little short.

Moreover, even in the society of dark blue ideology, it is impossible to match the higher and higher life expectancy at once - after the life expectancy of ordinary people reaches a certain value, it can not continue to rise.

On the contrary, the life span of extraordinary people can become higher, because extraordinary people are better at managing their emotions, more determined and better at thinking. But technology suck, and there is no way out.
