The world becomes strange, and deadly copies of rules appear randomly. Others narrowly escaped death inside, but Lu Yu was accidentally bound to the [Plane Exchange].
A rare "scapegoat"? Sell it to the dying rich man in the copy in exchange for an unlimited black card.
Murderous "ghost school rules"? Package it to the demon lord of the abyss in exchange for a drop of divine blood.
Worrying about money in the real world? A "Body Tempering Pill" from the world of immortality was put on the auction house and was worth a fortune.
When the whole world was afraid of darkness, Lu Yu discovered that these were his real business hours.
