Of course, facing Zhang Heng, these civilizations in the Milky Way and even outside the Milky Way can be destroyed with just one hand, but Zhang Heng has no need to do so. He can be regarded as the nanny of mankind at most, but the development of mankind ultimately depends on himself. Zhang Heng It can only be used as a trump card. Unless the destruction of mankind is imminent, Zhang Heng will not take action easily.
After all, Zhang Heng's opponent is still the dimensional star who stands at the same height as himself.
At this time, a star-class exploration ship belonging to humans is sailing at the cantilever edge of the Milky Way, exploring the unknown blank areas of the Milky Way and planning a star map. Even though the Milky Way already has three Level 3 civilizations, no one dares to say that they have explored the entire galaxy. Humanity has more than 10,000 stellar-level exploration ships traveling through the Milky Way all year round, unless there are two other Level 3 civilizations. territory, otherwise human exploration ships would dare to travel freely no matter where they are.
This kind of exploration ship has a variety of navigation methods. Generally, when exploring, the exploration ship uses a warp engine. This engine allows the spacecraft to compress space and cruise in the sea of stars at a speed exceeding the speed of light. This is a spaceship Basic regular sailing.
If there is an emergency, the exploration ship can also use space jump to open a wormhole directly in front of the spacecraft and instantly reach a space tens of thousands of light-years away. However, this kind of voyage must be to perform an emergency mission or encounter a dangerous situation. time to use.
In addition, there is also the subspace navigation method, because after reaching the second level civilization, many technological civilizations can invent the space silent stance, which is a kind of space interference wave that can prevent the spacecraft from making space jumps, so the subspace On the contrary, sailing is a way to escape when encountering a powerful civilization and the other party adopts a silent stance.
However, subspace is not stable. As the opposite of the universe, subspace has too many unknowns and dangers. Whether it is environmental dangers or the dangers of supernormal life in subspace, they are enough to destroy this group of uninvited guests. Therefore, unless it is It is a last resort, otherwise no civilization in the galaxy would choose subspace navigation.
At this time, inside the exploration ship, Gu Zhan was looking at the exploration instruments with a cold expression, recording the environment within a few light years. In the four hundred years since Zhang Heng disappeared, clone warriors like him had long been eliminated and were eliminated. He was replaced by more advanced biochemical warriors, and because of this, he did not die during Zhang Xu's purge. Later, with the help of Zhang Xin, he regained his feelings by modifying his genes and became a real person.
Later, Zhang Heng returned and once asked them if they were willing to return to Zhang Heng's command, but they all chose to give up. At this time, they had their own lives, and Gu Zhan's hobby was to explore the entire galaxy and experience The endless universe and countless unknowns.
At this time, his exploration ship is located at the edge of the Sagittarius cantilever among the four major cantilevers of the Milky Way. The material here is already extremely thin, hundreds of times thinner than the vacuum environment created by humans in the 21st century. A few dozen light-years away, the exploration ship has completely left the Milky Way and reached the void where matter is even thinner.
If the Milky Way is a forest, then the endless void outside the Milky Way is the barren desert. There is almost no matter in the space there, and the number of particles per square centimeter does not even exceed ten. This is an indescribable dark zone. , even the energy drawn from the void is pitiful, and because of the existence of dark energy, even opening a wormhole cannot lead to other river systems from the Milky Way.
Dark energy is an invisible force or effect that causes and accelerates the expansion of the universe. Until now, humans still don’t know what dark energy is, but humans know that dark energy is causing the expansion of the universe. The more the universe expands, the greater the distance between river systems becomes. Over time, dark energy isolates galaxies from the universe, making life within them ultimately inaccessible to other star clusters, galaxies, and groups.
Perhaps tens of billions of years in the future, galaxies beyond the Milky Way will be so far away that they will become difficult to detect, because only a small number of photons can reach the Milky Way, and the wavelengths of those photons will be too long to be detected.
Once this happens, no information from the outside world will reach the Milky Way, the light will disappear from view, and the universe will forever look dark and empty from every angle.
But today, at the edge of the Milky Way, Gu Zhan discovered a lot of matter slowly drifting in from outside the Milky Way on the radar of the environmental exploration instrument.
"What is this?" Gu Zhan squinted his eyes and looked at the shape of the substances projected by the exploration radar, only to find that those substances were like eggs, with a yellow-green color overall, and the outer shell seemed to be made of organic matter. The void of the universe floats, captured by the gravity of the Milky Way.
"Zhi Nao, scan." Gu Zhan said.
"The scan has been completed. The density of matter is around 7.4 g/cm?, the outer shell is silicide, and life fluctuations have been found inside. We are searching and comparing in the material library..."
"Warning, no one meeting the conditions has been found in the material library. It is suspected of being a new type of unknown life. It is recommended that the captain conduct capture analysis and receive rewards from the Stellar City government. Please pay attention to safety. Unknown life may be dangerous."
Hearing Zhinao's warning, Gu Zhan gradually frowned.
"Captain!" Behind him, several crew members looked surprised. They put down their work and walked over. They also heard Zhinao's analysis and suddenly became excited. In order to encourage people to explore, Star City will base on the findings of the exploration ship. Given corresponding rewards, and the rewards were extremely generous, at this time, these crew members swarmed in like cats that smelled fishy smell.
"Captain, this is a great discovery. Since we discovered space floating in three universe years, basically no new space species have been discovered. This is a great achievement!" someone said immediately.
"I know, but this kind of thing also has corresponding dangers. For the sake of insurance, which one of you is willing to explore it yourself?" Gu Zhan asked.
"I'll go!" A young man with a long camera immediately raised his hand and sighed, "Have you noticed that this kind of creature seems to have floated from outside the river system, which is amazing. You must know that because of the existence of dark energy, The galaxies outside the Milky Way are moving away from us at a speed faster than the speed of light. If we are the first to discover this kind of life outside the Milky Way, it may be a great discovery recorded in the history of galactic civilization! "
"Okay, then go ahead. Remember to be careful. If anything happens, return immediately." Gu Zhan nodded and watched the young man leave happily, but suddenly, a bad feeling flashed deep in his heart. premonition.
It seems that there is some danger slowly approaching...
