“…… Did someone bring it up in the meeting and want to go back and see it? Lin Xuanxuan leaned on Zhang Yuan's side and watched TV, she suddenly asked.

"Go back? What are you going back for? ”

"Didn't anyone propose it? There must have been a lot of first-generation people in the meeting. ”

Zhang Yuan thought for a while and said, "...... It seems that there is no need for this, after all, it takes time to fly back, and even if we have warp speed, it will take 800 to 1,000 years...... As for what happened to homologous humans, I think, alas, I can't care too much. We even told them a clue about how curvature technology was...... It's worth a little amoeba points, right? ”

"Social progress is not only scientific and technological progress, but if there are difficulties, they should be overcome by themselves."

"If it really becomes a civilization of the sunken, it may be eaten by the technology of the virtual world...... There was no need to go back......"

Lin Xuanxuan was silent for a while, the technology given to the homologous human virtual world was a very big double-edged sword! They may have developed tremendously as a result, or they may have been victimized by it, and they may have fallen into the same predicament as the "Brilliant Galactic Human Branch".

She can only secretly wish good luck to distant Earth civilizations and other branches.

……

A month later, the two had landed on the largest Titan-class spaceship, the Departure, and found their own accommodation.

The living environment in this large flying saucer-like spaceship is very complex, and it is like a big labyrinth. However, with the help of the auxiliary brain, there is no big problem in memorizing these functional areas, and 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 for one last drink.

Recalling the arduous journey along the way, everyone can't help but sigh, when it took three thousand years to drift to the destination in the Earth Era, who would have known that one day in the future, human beings would be able to become a real fourth-level civilization?

What was a journey of 3,000 years back then, now, is only ...... 10 years!

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

Li Zhendong, who likes to pretend to be forced the most, first began to show off his credit, and their team invented a fuzzy signal that can be used during faster-than-light travel, which is quite important when traveling at curvature.

"All the small ships will be mounted on the side of the big ships and taken with them. And the six large ships will be lined up in a diagonal pattern......"

"Slash, you know."

"Our Titan class will be at the front, giving orders to the ships diagonally behind, stop, accelerate, slow down, there are obstacles ahead, and so on."

"Due to the existence of the light barrier, the spacecraft in the rear can only receive the instructions of the spacecraft in front, but there is no way to issue commands to the spacecraft in front, which is quite a one-sided communication."

"So, the spacecraft in the rear, if there is something urgent, can accelerate to overtake the front, and then send a signal. Because of this, the entire fleet will not fly at maximum speed, at most 2.5 times the speed of light. ”

"Great work, very good plan!" Zhang Yuan profoundly knows that this work is very valuable, so Li Zhendong's pretense is not unreasonable.

"A toast!"

With a "bang", the two touched their glasses.

Suddenly, a few scientists who study subatoms are a little unhappy, you Li Zhendong is just engaged in a communication, and curvature technology is the big one!

Although it is only 3 times the speed of light now, and the great curvature of the planetary level has not been overcome, the credit cannot be erased!

Zhang Yuan hurriedly said: "I also toast you!" ”

Zhao Qingfeng shook his head and shrugged his nose there, the quark energy room is also very important, without the huge energy support of this thing, the curvature is a fart! Quark can not be made by them?

"A toast!"

Several experts in the virtual world are not very satisfied, even a dead house like Ichiro Yamamoto is rolling his eyes there, if there is no virtual world technology, you group of people would have been dead for thousands of years, and it is your turn to brag and fart here?

There are no ashes left of the dead!

Throw it into the stars!

Zhang Yuan suddenly understood...... This group of people is banding together to fool him!

Because his old Zhang is so famous, he has suppressed all scientists more than one, and even his fame has been passed on to another civilization!

In recent times, communication with the Thoth civilization has been based on curvature spaceships, and no longer uses electromagnetic waves.

In the words of the Toth people, they are simply grateful to Zhang Yuan, half of the pages are in praise and sighing "optical perception", and then praise Zhang Yuan, it is best to be able to kidnap Zhang Yuan, if Zhang Yuan can join the Toth civilization, it would be better!

Half of the space is the main thing......

So this bunch of guys is a little upset.

"You're or I'm bullish!" Thinking of this, Zhang Yuan suddenly patted the table very unceremoniously.

Everyone burst out laughing.

Speaking of the old friend of the Toth civilization, it is a pity that they cannot act together. But there are countless possibilities in the future, and there is always a time to meet.

A scientist suddenly sighed: "Actually, every civilization is very difficult...... We humans have had a tumultuous time in these centuries. But who knows what difficulties the Torth civilization has experienced in these tens of thousands of years? ”

"Without eyes, maybe on a practical level, they are more difficult than we think."

"yes." Zhang Yuan nodded in agreement.

"Now that we have worked so hard and are already a fourth-level civilization, how should we reach a fifth-level civilization?"

"So far, there's no good way to do it...... You can only taste it there. Zhang Yuan shook his head, "We still lack a lot, first of all, a fourth-level civilization with an average lifespan of six or seven hundred years, have you ever seen it?" ”

"It's a bit pitiful, isn't it?! The fourth-level civilization is also well developed in the galaxy, and it can only live for six or seven hundred years, shame on you! ”

Now scientists have gone to great lengths to raise the average life expectancy of humans to 700 years, but this life expectancy is still a little shorter.

Moreover, even a society with a deep blue ideology cannot match the higher and higher lifespan at once - after the lifespan of ordinary people reaches a certain value, it cannot continue to rise.

On the contrary, the life expectancy of the transcendent can be higher, because the transcendent is better at managing their emotions, more determined, and better at thinking. But if the technology is not powerful, there is no way.
