The Evil God's Scales

“The Absolute Judgment has sensed your desire to cultivate. Peerless elixirs, immortal dew and nectar, ancient secret texts, ghostly artifacts and divine weapons... It can trade them all to you. But what will you give in exchange for this desire? Your lifespan, soul, body, memories, senses, love...”

The Evil God’s Scales can respond to the desires in people's hearts, allowing them to fulfill those desires through exchanges involving themselves or external objects.

The scales are fair and impartial. Equivalent exchange is the only law.

As their master, the only thing he needs to do is cleverly exploit the rules.
