Chapter 691: Premonition

"That said, you are not only as simple as your aunt, but your grandma's level is not enough to describe."
After hearing Zhihan's explanation, Yunyue couldn't help but laughed out loud.
A somewhat embarrassed look at Yun Yue, Zhi Han had no choice but to turn his head depressed.
It is estimated that there is no need for her to lie about this matter. Yunhai glared at Yunyue, then looked at Zhihan and asked, "If everything you said is true, then we will start from here and arrive at the central black hole in the Moyun River System. ,Roughly how long will it take?"
"Do you really want to go now? This is not a rational decision!"
Zhi Han was taken aback, and quickly persuaded: "Don't be dazzled by Yunyue's words. It is absolutely irrational to run rashly before things become clear."
"I know."
Yunhai smiled and nodded, and said, "Actually, I just want to know if the spacecraft carrying you to this river system can still fly, how long will it take to fly to the central black hole at its maximum speed?"
In the vast universe, what hinders the communication between different civilizations is not prudence, nor is it the difference of civilizations, but distance.
Perhaps for a super civilization that is unimaginable for intermediate or even high-level civilizations, distance may no longer be a problem.
But for more civilizations, distance will always be the biggest issue that hinders the development, exchange, and even aggression and war of civilizations.
A river system can be hundreds of thousands of light-years away.
Even if the structure and shape of the river system are different, it is a very difficult and time-consuming project for a planet with life to explore the entire river system, which cannot be completed by one or several generations.
Not to mention the exploration outside the river system, at least for the third-level technological civilization, it is simply an impossible task.
This problem also plagues the current sea of ​​clouds.
All aliens, including the sea of ​​clouds and alien beast aliens, only have the speed of light.
At this speed, even if everything is normal and there is enough food in the middle, or the mysterious substance similar to the gas giant planet in the ruins, it can supplement the energy consumed by the long journey.
The distance of 30,000 light-years is actually not far from the river system.
But such a distance means that the sea of ​​clouds will take a full 30,000 years to reach the central black hole of the Moyun River System while maintaining the speed of light at all times.
Moreover, this "30,000 years" is still relative to the silver dragon empire's chronological unit. If it is replaced by the earth's chronological unit, this time will be even longer.
So Yunhai wanted to know how long it would take for Zhihan's parent star spacecraft to complete such a distance.
"If the spacecraft can still make a space jump, in my estimation, from here to the position of the central black hole, considering not to jump too aggressively into the edge of the black hole and be pulled in, then two or three jumps are still necessary."
"Three spatial transitions, with sufficient energy, will probably take one to three hundred years."
When Zhi Han said this, Yun Hai suddenly became a little uncomfortable.
"How is it possible? The space transition is just a momentary thing, and the three space transitions will take one to three hundred years to complete?"
Yun Hai asked in surprise.
With a wry smile, Zhihan explained: "What I'm talking about is the best prediction. The problem now is that I don't know if the spacecraft can fly, let alone the more challenging space leap."
"The dilapidation of that spaceship is absolutely beyond your imagination."
"Space jump technology has very high requirements on the material, engine, etc. of the spacecraft itself. Even if that spacecraft can barely make a space jump, and it can succeed, the subsequent maintenance is definitely not an easy task. After all, we want to complete Complete the space transition, not the final disintegration."
Zhihan was explaining, seeing Yunyue's face with a contemptuous look, and hurriedly distinguished: "I have emphasized that it is a broken spaceship. If it is intact, there will be a professional elite team perfectly Calculate. A space transition, at most a few long hours of preparation, can reach the destination in an instant."
Cursing her lips, Yun Yue mumbled: "Said it means not saying it."
The mood was obviously depressed, and Yunyue didn't even have the interest to say a few more words.
The distance is too far, it is desperate.
It is a distance of hundreds to thousands or even tens of thousands of light-years, which is simply desperate.
If the current situation remains the same, Yunyue estimates that he will fly all the way, not to mention exhaustion and old age, she will definitely die of boredom-in the empty and void universe, the most deadly thing is not all kinds of radiation and unknown energy invasion. It's the loneliness that is suffocating.
"I have a hunch that distance from these will not be a big problem. The most troublesome thing is that I don't understand where the danger comes from."
Yun Hai sighed as he spoke.
Existence 30,000 light years away, it did not mention that wandering civilization.
In Yunhai's view, this is the biggest problem.
It may ignore the existence of Zhihan and Qi Fei, after all, it is a living body, not a machine, and there are always times of negligence.
But now, it can notice the existence of the sea of ​​clouds and aliens, but cannot detect the invasion of an advanced wandering civilization.
Is it deliberately tested, or has other plans.
Yunhai has no way of knowing.
He can't even judge.
"Arrived."
At this moment, Yunyue spoke suddenly.
Moving his gaze out of the window, Zhi Han couldn't help but rushed to the observation window with just one glance, looking at her, wishing to get out.
In the dark universe, a behemoth greeted him silently.
There is no need to think about it, Zhihan knows who it is.
Except for the alien beast alien that Yun Yue mentioned from time to time, Zhi Han couldn't think of another alien that could possess such a huge size and terrifying aura.
Domineering and fierce.
Zhi Han even felt that the alienated sea of ​​clouds was not as terrifying as the alien beast alien.
Of course, this may be due to the fact that Yunhai is not "pure" enough. There are naturally differences between the complete alien and alien and human fusion.
"So strong!"
Seeing the alien beast and alien greeted him, and finally flew slowly together not far from the assault ship, Zhi Han couldn't help sighing.
However, in an instant, it was obvious that he received a spiritual order from Yunhai, and the alien beast alien increased its speed, and after flying around the assault ship, it flew away quickly in the direction of the blue star.
"Change the course, don't go back, let's go to the ruins."
Yunhai watched the alien beasts disappear into the dark universe, and at the same time said to Zhihan.
"It's time to go there and have a look. This time, I want to know what the radiator in the Aite Nebula is all about."
"By the way, let the Cerebral Worm Alien try to complete the evolution. After all, its existence may exceed the value of the Alien Beast."
Mumbling, Yun Hai's eyes changed direction.
Endless stars, dark universe.
At a glance, there seemed to be nothing unusual.
But Yunhai knew that in that direction, at the edge of the central black hole 30,000 light-years away, there was a pair of eyes colder than the universe, watching him.
