Ma Baobao opened his eyes.

He saw a flickering oil lamp.

It was demon oil refined from the fat of sea monsters hunted in the depths of the ocean.

It was used to suppress and restrain some extremely dangerous people!

That was a secret that his disciple had told him.

He then looked at the walls on both sides, which were completely bare.

One talisman after another was emitting a faint spiritual light.

"Demon Suppression Prison!" He spat out a word.

The most secretive and highest-level prison of the Blackguard!

It was a place specially used to lock up extremely dangerous foreign species or transcendent beings.

It was said that anyone who entered such a place could not escape easily, no matter who it was.

A hundred years ago, there was once an extremely powerful demon that was locked up in the Demon Suppression Prison.

Then, it was suppressed until it died!

"What did I do?" Ma Baobao couldn't figure it out.
