Chapter 635

Of course, in the face of Zhang Heng, these civilizations in the galaxy and even outside the galaxy can only be destroyed by hand, but Zhang Heng is absolutely unnecessary. He is at most the nanny of human beings. However, the development of human beings ultimately depends on themselves. Zhang Heng can only be used as a card. Unless the destruction of non-human beings is imminent, Zhang Heng will not easily do so.

After all, Zhang Heng's opponent is the star of dimension standing at the same height as himself.

At this time, a star class exploration ship belonging to human beings is sailing in the cantilever edge of the galaxy, exploring the unknown blank area of the galaxy and planning the star map. Even though the galaxy already has three tertiary civilizations, no one dares to say that he has explored the whole river system. There are more than 10000 constant star exploration ships passing through the galaxy all year round. Unless it is the territory of the other two third level civilizations, human exploration ships will dare to go through it at will.

This kind of exploration ship has a variety of navigation modes. Generally, during the exploration, the exploration ship adopts a curving engine, which can make the spacecraft compress space and cruise in the sea of stars at a speed exceeding the speed of light, which is the most basic routine navigation of the spacecraft.

In case of emergency, the exploration ship can also use space jump to open the wormhole directly in front of the spacecraft, and instantly reach the space tens of thousands of light-years away. However, this kind of navigation can only be used when performing an emergency mission or in case of danger.

In addition, there are also sub space navigation, because after reaching the second level of civilization, many scientific and technological civilizations can invent the space silent position, which is a kind of space interference wave, which can prevent the spaceship from jumping in space. Therefore, the sub space navigation is a way to escape when the strong civilization meets and the other party opens the silent position.

However, the subspace is not stable. As the opposite of the universe, there are too many unknowns and dangers in the subspace. Both the environmental risks and the dangers of the unconventional life in the subspace are enough to destroy these uninvited guests. Therefore, unless it is absolutely necessary, civilization in the galaxy will not choose this way of sub space navigation.

At this time, Gu Zhanzheng looked at the exploration instrument coolly, recording the environment within a few light years. In the 400 years of Zhang Heng's disappearance, clone fighters like him had already been eliminated and replaced by more advanced biochemical soldiers. Because of this, he did not die in Zhang Xu's great cleaning. Later, with Zhang Xin's help, he passed through Modifying genes, regaining emotion, and becoming a real person.

Later, when Zhang Heng returned, he once asked them whether they would like to continue to return to Zhang Heng's command, but they all chose to give up. At this time, they had already had their own lives. Gu Zhan's hobby was to explore the whole galaxy and experience the endless universe and countless unknowns.

At this time, his exploration ship is located at the edge of the four cantilevers of the Milky way, where the material is already extremely thin, hundreds of times thinner than the vacuum environment created by human beings in the 21st century. If it goes further for dozens of light years, the exploration ship will completely leave the galaxy and reach the emptiness with thinner matter.

If we say that the Milky way belongs to the forest, then the endless void outside the galaxy is the desert. There is almost no matter in the space there. The number of particles per square centimeter is not even more than 10. This is an indescribable dark zone. Even the energy drawn from the empty sky is very little. Moreover, because of the existence of dark energy, it is even opened Wormholes cannot travel from the Milky way to other rivers.

Dark energy is an invisible force or effect that causes and accelerates the expansion of the universe. Until now, we still don't know what dark energy is, but we do know that dark energy is causing the universe to expand. The more the universe expands, the greater the distance between the river systems. Over time, dark energy isolated the river systems from the universe, making life in the river system unable to reach other star clusters, galaxies and groups.

Perhaps tens of billions of years from now, galaxies outside the Milky way will be so far away that they will be hard to detect, because only a small number of photons can reach the Milky way, and those photons will have wavelengths too long to be detected.

Once this happens, no information from the outside can reach the Milky way, the light will disappear from view, and the universe will always look dark and empty from any angle.

Today, however, at the edge of the Milky way, Ku Zhan has found a lot of material slowly drifting in from outside the galaxy in the radar of the environmental exploration instrument.

"What is this?" Gu Zhan narrowed his eyes and looked at the shapes of the materials projected by the exploration radar. However, he found that those substances were like eggs, which were yellow green in color, and the outer shell was like organic matter, floating in the void of the universe. The gravity of the galaxy captured them.

"Brain, scan." Gu Zhan said.

"The scanning has been completed. The material density is about 7.4gcm? And the outer shell is silicide. Life wave is found inside. We are searching the material library for comparison..."

"Warning, no one who meets the conditions in the material library is suspected of a new type of unknown life. It is recommended that the captain carry out capture analysis and obtain the government reward of star city. Please pay attention to safety. The unknown life may be dangerous."

Hearing zhinao's warning, Gu Zhan gradually frowned."Captain!" After that, several crew members showed surprise and put down their work one after another. They also heard the analysis of wisdom brain and became excited. In order to encourage people to explore, star city will give corresponding rewards according to the discovery of the exploration ship, and the rewards are very rich. At this time, these crew members are like cats smelling fishy smell.

"Captain, this is a great discovery. Since the discovery of space plankton in three space years, we have basically not found any new space species. This is a great credit." Someone said immediately.

"I know, but this kind of thing also has corresponding danger. For the sake of insurance, which one of you would like to explore it personally?" Gu Zhan asked.

"I'll go!" A smart looking young man immediately raised his hand and exclaimed, "have you noticed that this kind of creature seems to have come from outside the river system, which is amazing. You know, because of the existence of dark energy, the river systems outside the galaxy are moving away from us at a speed faster than light. This kind of life outside the river system is first discovered by us, which may be enough to become a great record in the history of civilization in the galaxy What a discovery

"Well, then you go. Remember to be careful, and if anything happens, return immediately." Gu Zhan nodded and watched the young man leave happily. But suddenly, a bad feeling flashed through his heart.

It seems that there is a danger, slowly approaching
