Lu Lingyu was a mean man playing mahjong with Lord Yama of the underworld. After he owed 99.99 Million spirit beads, he signed an unequal treaty and spent 999 years in the mortal world to help him settle the evil spirits that harmed people in the world.
"Nine hundred and ninety-nine years, why don't you just come for a thousand years!"
"Everything has been signed, and it is impossible to go back on it."
Lu Lingyu was almost mad at this bitch, so he had to accept it.
Purpose: Gods save people
