"Is this a black wall that surrounds the black hole?" Henry exclaimed.

The door he stepped into was a black metal door. The entire black hole was wrapped in this mysterious material, forming a super huge spherical black barrier!

This is a man-made building!

It's like locking a black hole in an iron ball.

The cliff he entered when he opened the door was the prison of the black hole.

Because it is also extremely dark, I never expected that someone would create such things that imprison black holes. So when I first came, I instinctively thought that this black prison was the black hole horizon.

This black hole is already very large. According to his previous estimates on Earth, its horizon has a diameter of at least 600 million to 800 million kilometers, and its mass is 100 million times that of the sun.

One hundred thousand years later, the entire Milky Way will become its vassal.

But such a super-large black hole was locked up by a larger prison. This prison is estimated to have a diameter of at least one billion kilometers.

Inside the prison, one tenth is a vacuum, nine out of ten is a vision, and finally there is a singularity.

It's like an egg structure.

"Incredible, I actually used such a magnificent prison to imprison a black hole! The great hand of the Galaxy, as long as this iron wall is used, can the black holes prevent the galaxy from tearing apart and devouring our hunter's arms in the future?" Henry murmured, crying in emotion.

Such a powerful existence actually protects them so much, which makes Henry feel that this is the ultimate guardian civilization of the universe in science fiction?

When his tears evaporated directly by the blue and white light, luck came again, and he finally heard the answer of the mysterious existence.

It was the sound that echoed in his mind, in his native language.

"Don't cry, I hate crying."
