My disciple's cultivation returns ten thousand times, so I have to be invincible.

Zhong Qing raised an eyebrow: "Numbers 2 to 7? What about number 1?"

"This... I don't know, number one is not here, it is said to be in the center of the fairyland."

"But the environment here is extremely harsh. It is the most remote star field in the Xuqi Immortal Region. Only those who have committed extremely serious crimes are sent here."

"Just now, the Lord Prison Master also said that even the closest life star, the Wind Sea Star, has three thousand immortal dwellings."

"And among them, let alone life-bearing stars... there aren't even any desolate stars. There are a few dark stars, though."

"Even if the prisoners escaped the star, they wouldn't be able to fly this distance. So, Immortal, your earlier statement that they had stumbled upon this place was a bit..."

Zhong Qing's mouth twitched. "Don't worry about that for now. Let's continue. What is the Xuyuan Sky Region? Is it referring to this galaxy?"

"Also, how far is the Three Thousand Immortal Houses?"

After Xie Pengfei's explanation, Zhong Qing roughly understood after a while.

In the outside world, galaxies like this are called celestial regions.

To be precise, the area consisting of a single sun and the surrounding large stars is called a small sky area, and many close small sky areas are divided into one place and collectively called a sky area.

The Xuyuan Sky Region is the black hole galaxy where they are located.

This place is quite special. Apart from the black hole they call Urobuchi and another sun orbiting the Urobuchi black hole, there are no other small celestial areas in the surrounding area.

As for Xianshe, it is a unit of distance.

The distances between celestial regions are so great that it is difficult to measure them in miles, so they are measured in immortal houses.

In the ordinary world, one house is thirty miles.

And three trillion miles is a fairyland.

Zhong Qing was so surprised by the huge number.

But considering that this is the real starry sky, compared with the distance between the stars, this is nothing.

According to his previous life, which used light years as the unit of distance, one light year is equivalent to more than 9.4 trillion kilometers, which is much larger than this so-called fairy house.

By this calculation, the distance between Liuxianshe and Liuxianshe is about one light year.

The Xuqi Immortal Area covers a million immortal houses, which means that the area over 150,000 light years belongs to this immortal area.

This range is not small. The Milky Way where the Blue Star was located in the previous life was only 100,000 light years away.

The Prisoner Star Domain Lord had said before that the nearest Wind Sea Star was outside the Three Thousand Immortal Houses.

It is about 500 light years away.

More than 500 light years may not seem like a large number, but if one really wants to cross it in the flesh, the difficulty is unimaginable.

Let’s not talk about how to find a way to return to the Ninth Heaven. If we want to turn around and go to the Xuqi Fairyland, we may have to rely on the teleportation array on this planet.

While Zhong Qing was thinking, he raised his head and looked at the sky outside the hall.

At this distance, he could clearly see two suns hanging in the milky white sky, one in the east and one in the west.

Yes, there are indeed two.

One of them was the sun they had just seen when they walked out of the Ninth Heaven. It was hanging in the corner of the western sky and seemed a little inconspicuous at this time.

The other one was not actually the sun, but the black hole where the Ninth Heaven was located and from which they came out.

It’s just because the halo around it is too bright. When standing on this Prisoner Star, it looks like a huge and amazing sun that occupies half of the sky, but is somewhat dim.

If you didn't know where you were, this scene would be considered a spectacle.

But it is also thanks to the people in the Xuqi Immortal District that they thought of placing the Prisoner Star here.

This place is indeed a natural cage.

The thought of a planet next to a black hole is terrifying.

Even without restrictions, it would be almost impossible for anyone to escape from here.

What is even more difficult to imagine is that the Nine Heavens where they came from, which is like the fairyland, is actually inside a black hole?

Until now, Zhong Qing still couldn't figure out how the Nine Heavens existed in this black hole of Xuyuan.
