"If you say so, you are more than just an aunt, and your grandma's level is not enough to describe it."

After hearing Zhihan's explanation, Yun Yue couldn't help but laugh out loud.

He looked at Yun Yue awkwardly, and Zhihan had no choice but to turn his head in depression.

It is estimated that there is no need for her to lie about this matter. Yun Hai glared at Yun Yue, then looked at Zhihan and asked: "If all you said is true, then how long will it take for us to start from here and arrive at the location of the black hole in the central Moyun River System?"

"You really want to go now? This is not a rational decision!"

Zhihan was stunned and quickly persuaded: "Don't be blinded by Yun Yue's words. It would be an irrational behavior to run rashly before things are clear."

"I know."

Yun Hai nodded with a smile and said, "Actually, I just wanted to know, if the spaceship carrying you to this river galaxy could still fly, at its maximum speed, how long would it take to fly to the central black hole?"

In the vast universe, what hinders the exchange of different civilizations is not caution, nor the differences between civilizations, but distance.

Perhaps for super civilizations that are unimaginable to intermediate or even ordinary advanced civilizations, distance may no longer be a problem.

But for more civilizations, distance is always the biggest problem that hinders the development of civilization, communication and even invasion and war.

A river galaxy can often last more than 100,000 light-years.

Even if the planet with life wants to explore the entire river galaxy because of the different structure and shape, it is a very difficult and time-consuming project, and it cannot be completed in one or several generations.

Not to mention the exploration outside the river, at least for the third-level scientific and 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 beasts, only have the speed of light.

At this speed, even if everything is normal and there is enough food in the middle, or mysterious matter similar to the gas giant planet in the ruins, can replenish the energy consumed by long journeys.

The distance of 30,000 light-years is actually not far from the river galaxy.

But such a distance means that the sea of ​​clouds always maintains the speed of light and takes 30,000 years to reach the position of the black hole in the central Moyun River.

Moreover, this "30,000 years" is still relatively the annual unit of the Silver Dragon Empire. If it is replaced with the annual unit of the Earth, the time will be longer.

So Yunhai wanted to know how long it would take for Zhihan's home planet spacecraft to complete such a distance.

"If the spacecraft can still make space transitions, according to my estimate, from here to the central black hole position, considering that you should not jump too radically into the edge of the black hole and be pulled into it, then two to three transitions are still necessary."

"Three spatial jumps, when energy is sufficient, will take about one to three hundred years."

When Zhihan said this, Yun Hai was immediately a little uneasy.

"How is it possible? Space jumps are just a matter of momentum. Three space jumps take between one to three hundred years?"

Yun Hai asked in surprise.

With a wry smile, Zhihan explained: "I'm talking about the best predictions. The problem now is that I don't know whether the spacecraft can fly, let alone the more challenging space leap."

As he murmured, Yun Hai's eyes changed direction.

Endless stars, dark universe.

At first glance, there seemed to be nothing unusual.
