Voyage of the Stars.

Chapter 978 Time Span
Thousands of years of ups and downs.

Thousands of years have passed since humans and the Dyadic cat civilization developed somewhere in the Orion spiral arm.

Thousands of years of peaceful development have allowed both civilizations to regain their former strength, with humanity even more powerful than before. The number of star-class fleets has reached a record high of more than six million, and construction is still ongoing.

The industrial capacity of a level five civilization is extremely powerful. Many star systems in this star field have been hollowed out by humans and the Dayan civilization. If it weren't for the lack of technology to quickly extract stellar energy, it is estimated that no star would be spared.

However, in this case, even if they had that ability, humans and Dayan civilization would not do it, because both civilizations knew that attacking stars would most likely attract the attention of other civilizations.

However, even if they did not destroy the star or exploit its resources, at the beginning of the next millennium, the two civilizations had already decided to leave this star region.

Having stayed in one place for thousands of years and hollowing out many planets will change the optical phenomena of these stars. Many civilizations can judge the abnormal phenomenon of the disappearance of planets based on this optical change, and thus know that there are signs of civilization activities here.

For example, at first, the periodic change in the brightness of a star is observed through the planetary transit method, but suddenly this periodic change disappears, which means the planet must have suddenly disappeared.

The more advanced the technology, the easier it is to observe such changes. Conversely, advanced civilizations will always pay attention to the impact of their own behavior on the universe, and whether these impacts may expose themselves.

As an old fifth-level civilization, the Daya civilization is naturally well aware of this. Human civilization has developed by hiding from place to place, and is also well aware of this.

Therefore, the two civilizations hit it off and shifted their positions in tacit understanding.

During these thousand years, humans, as a primary level five civilization, have actually been catching up with the Daya civilization in the field of science and technology.

After thousands of years of development, mankind has made great progress in every field. In many fields, it has caught up with the Daya civilization, an old fifth-level civilization. In some special fields, such as the microscopic field, it is far ahead.

However, biotechnology is still humanity's weak point.

Humans didn't discover it before, but now it's easy to discover it with the Daiyan civilization, a veteran fifth-level civilization, as a comparison. Some biotechnologies that should have been available long ago have not been realized by humans.

The body-strengthening technology that humans are so proud of is, in the eyes of the Daya civilization, only the technology of the fourth-level civilization, which is completely outdated.

When human scientists were communicating about technology with the Dayan civilization, they did not believe it until the Dayan civilization introduced their own biological enhancement technology. Only then did human scientists suddenly understand what tenacious alien life forms were.

Because some of the data of individual life forms of the Daya civilization are so powerful, although their individual lives appear soft and sticky, they are extremely powerful.

Yes, after so many years of getting along, humans and Dayan civilization have achieved a great deal of mutual trust. Both sides already know what each other's individual lives look like, and in further biotechnology exchanges, they have learned some basic biological data of each other.

The individual life forms of the Daya civilization are soft-bodied and carbon-based.

They have no bones and are extremely tough. If they were under the Earth's gravity, they could jump directly from a plane and not die. At most, they would break into several sticky pieces. If they were put back together, their cells would quickly stick together according to their memory.

They look like super rubber and have strong self-healing properties. Even if they are pierced or split, they can recover. Their resistance to high-G shocks is several times that of humans in an overclocked state.

Even if their brains are blown up, as long as they are given enough energy, their cells can regenerate a new brain. They only need to reset their consciousness and the individual life with the blown up brain can be resurrected. They can even survive for a long time in space without relying on any equipment.

After knowing this situation, humans finally understood why the Daya civilization always stayed on the wreckage of some of their own warships for a long time when cleaning up the battlefield. It turned out that they were rescuing survivors.

What surprised humans was that the warships or spaceships of the Daya civilization did not create an environment that simulated the gravity of their home planet like humans did. Their advanced biotechnology had made them fully adaptable to various gravity environments.

Although humans are stronger than the Daya civilization in terms of combat power, the Daya civilization is indeed an old-fashioned level five civilization, and their technology is far superior to that of humans.

Over the past thousand years, humans have been developing, and the Dayan civilization has also been developing. It is not only humans who are progressing.

It’s just that many technological accumulations are not directly reflected in combat effectiveness. After all, the progress of a civilization is not limited to war capabilities.

Perhaps inspired by the biotechnology of the Daya civilization, humans were lucky this time. At the end of the first millennium, a new life potion was successfully developed. Unlike in the past, it was not developed until everyone was almost dead of old age or at the critical moment.

The effect of this life potion lasts for 30,000 years.

Humans have become accustomed to the fact that technological progress has led to a significant increase in life expectancy, but when the results were announced, it still sparked great discussion in society.

At this moment, hundreds of billions of humans who longed for longevity were sincerely grateful to those tireless life scientists, except for the inhabited spaceship that gathered a group of rebellious humans.

The moment the success of the potion was announced, the interstellar government had clearly informed the general public that those people were not qualified to use it, either now or in the future.

The interstellar government's resolute attitude made everyone understand that there was a price to pay for inciting internal unrest among humans, and those people would never be able to leave that spaceship until they died of old age.

At this moment, inequality finally appeared in the face of death among human beings, but the society applauded. Many people even felt that the punishment was too light and that the death penalty should be imposed.

Time will dilute everything. When the second millennium is halfway through, many people have forgotten the existence of such a group of people. They don’t even know that some of those people have died of natural causes.

The people on the spaceship found that they had white hair without realizing it, which was something they had not thought about for thousands of years. When they saw the people around them becoming old and frail, they finally shouted to the sky. They were talking to the interstellar government, but just like fifteen hundred years ago, no voice responded to them.

This year, the new flagship of the Daya civilization was also born. Just like the human Lyra, the entire ship's surface looks watery, like flowing liquid. It is undoubtedly quark material armor.

The Daya civilization spent 1,500 years and used all of its entire industrial strength to build such a flagship, and they named it: Daya.

In the year when it was completed and put on sea trials, they drove the Daya to the human star system for a tour, with a feeling of showing off. However, after they found that the Lyra was passing by them at 130 times the speed of light, the Daya returned to its dock without a word, as if it was hit.

After so many years of getting along, humans and the Daya civilization have established a considerable degree of strategic mutual trust. The two civilization groups now actually have a very friendly relationship. If nothing unexpected happens, the two civilizations may continue to travel together.
