Water Margin: The Twelfth Layer of Subduing Demons

When I fell from the twelfth floor, I thought I was dead.

But I woke up to find myself standing in an unfinished building, with a copy of The Water Margin's Demon-Suppressing Chronicles in my hand.

It said: Suppress the Demon Lords, and you can live.

The first floor held the Earth Dog Star, the second the Earth Thief Star, the third the Earth Health Star...

Twelve floors. One hundred and eight Demon Lords.

If I don't climb to the top, I'll really die.

But halfway up, I discovered something: every demon-suppressor eventually becomes a Demon Lord.
