Homo sapiens.

Chapter 688
Galaxy for 382 years.

More than 34 earth years have passed since the artificial earth No. 270 left the giant star colonization branch.

In order to reduce the speed of resource consumption during the voyage, the Scarlet Heart Group adapted from the Scarlet Heart Legion adopts a shift system, usually only 10% of the members are on duty, and the remaining members all enter the absolute zero dormancy cabin.

At this time, the average life expectancy of new humans has reached about 1258 years. If the absolute zero freezing and dormancy technology is used, the survival time can be further extended.

Gao Long, who had just participated in the 27th (every 10 years) Science and Technology and Culture Exchange Conference, looked a little unhappy at this moment.

As soon as he exited the virtual world, he immediately summoned the core researchers of Chixin Group's Science Division.

As one of the heads of the Chixin Group's Science Business Department, Gao Long was in charge of leading the delegation to participate in five exchange conferences, but this exchange conference shocked him very much and brought some bad news at the same time.

After nearly 300 years of continuous development by new humans.

At present, the new human civilization controls not a few planetary systems.

包括距离太阳系4.2光年的比邻星系（含南门二AB星）、5.9光年的巴纳德星系、8.7光年的鲁坦726-8AB星等32颗恒星。

Among a series of planetary systems occupied by humans, the most distant planetary system from the solar system, the place where human civilization originated, is the Lutan galaxy 12.4 light-years away.

The reason why these planetary systems can be reached is, on the one hand, that the overall technology of human civilization is constantly improving.

For example, the series of four-neutron materials and six-neutron materials have been synthesized successively, and eight-neutron materials have been researched so far.

The advent of these neutron materials has led to rapid advances in energy, shielding and thruster technology.

At present, human technology can increase the safe navigation speed of spacecraft to 18.6% of the speed of light.

Although there is no way for a mothership of the level of artificial earth to increase its speed to 18.6% of the speed of light, this allowed Chixin Group to obtain a colony in advance.

The Chixin Group transforms spaceships and space battleships, and then allows these spaceships to go to the destination in advance - the Lakai 9352 galaxy.

The Lakai 9352 galaxy is 10.7 light-years away from the solar system and about 8.6 light-years away from the giant nebula.

According to the previous sailing speed of the 34th man-made earth (1.8% of the speed of light), it will take about 480 earth years.

But using an improved version of the spacecraft, it only takes about 46 years to reach the Rakai 9352 galaxy.

The Lakai 9352 galaxy is a single main sequence star, its stars are red dwarfs, and its resources are not bad.

The branches of human civilization that spread around the solar system have found traces of life in almost every galaxy.

However, among planetary systems with civilizations, apart from the solar system and giant nebula, only two of the planetary systems with 32 stars have intelligent life forms, and they are all rookies in zero-level civilizations.

If the Six Claws hadn't picked the wrong opponent, they probably wouldn't have ended up exterminating their clan.

The various sub-civilizations with a large number of colonies have also begun to catch up with the technological level of the parent company of the solar system in the past 100 years or so, and no longer rely solely on the parent company's blood transfusion technology.

It is precisely because of this that at this technology and cultural exchange conference, the Sirius Group from the Sirius galaxy unintentionally researched some mysteries about the soul.

This achievement caused a thousand waves with one stone.

It immediately shocked the entire scientific community of human civilization.

After all, the development of human civilization over the past 300 years has not been smooth sailing.

One of the most troubling issues is longevity.

You must know that human beings now claim that the average life expectancy can reach thousands, but the first generation of founders of human civilization are only more than 400 years old at most.

The so-called life expectancy is nothing more than an assessment of the body.

Even in Xinghe 236, Li Qingye led a scientific research team to complete the cosmicization of human genes, reshaped human genes, and made the new human beings in the universe and natural people truly form reproductive isolation.

And this technology has also allowed the average life expectancy of new humans to reach thousands of years.

But when everyone was immersed in this great achievement, a crisis was quietly brewing.

It wasn't until Galaxy 331 that the hidden crisis finally spread gradually.

The terrible disease of "neurasthenia syndrome" appeared for the first time in this year. The characteristic of this disease is that the body is very healthy without any abnormality, but the human spirit will continue to weaken, and then memory confusion and loss will occur. , and finally become the living dead.

Any new human over the age of 360-370 will have neurasthenia syndrome.

At present, there is no cure for this disease, and the various sub-civilizations are better. After all, there are not so many old people, but the problem is very serious on the parent company of the solar system.

At this stage, we can only adopt a conservative treatment plan, and send all the new humans over 300 years old to the absolute zero freezing chamber.

All the veterans of the company, including Li Qingye, have now entered a long-term dormant state.

But this time Gao Long, who came back from the exchange meeting, heard bad news. Freezing hibernation can only delay the speed of soul decay, but at most it can only delay 3 times the time.

Take Li Qingye as an example. He had frozen himself for a long time due to genetic modification, but it was a blessing in disguise. Now his soul life is still about 124 years.

In addition to the cryogenic hibernation at absolute zero, if he remains in the cryogenic hibernation, he can persist for a maximum of 372 years.

If within this time limit, human civilization does not develop the technology to treat the decay of the soul, then Li Qingye will be lost.

Gao Long, as the second-generation new human of the Chixin Group, is 233 years old, and he is actually approaching the limit of soul decay.

Before that, he also wanted to freeze the hibernation chamber at absolute zero to delay the time to thousands of years later.

Thinking about it now, he was too optimistic.

He suppressed the helplessness and unwillingness in his heart, and looked at everyone present: "Everyone! I think you already know about this exchange meeting."

These members of Chixin Group's scientific business department are all top scientists, and they also participated in this exchange conference, so they naturally know what Gao Long means.

"Minister! We don't have much time left. We need to develop a treatment plan in a short time. One word! Difficult!" A bald scientist shook his head.

"Perhaps this is the limitation of the universe on life!"

Obviously, none of the scientists present had any hope.

Like Li Qingye, they have benefited from the long-term frozen dormancy, and now they still have a lot of time.

Judging from the information obtained from the exchange conference, they only know that the soul may be composed of dark matter and dark energy.

Dark matter and dark energy, these two things are too mysterious, even if human civilization has developed for hundreds of years, they are still in a state of being glimpsed.
