Thirteen prisons

Chapter 1 Introduction
The Buddha said: If you create evil karma, you will fall into the pool of blood hell.

He also said: There are vicious insects in the prison, named Zhuzhu, who specialize in sucking the blood of sinners, causing them to wither and die.

"Ksitigarbha Sutra" says: There is a lake of blood in it, which is caused by Zhu Zhuchong drinking the blood of sinners.
