Ten thousand years ago, the demon lord told the monk that he would let the monk into the sacred palace. The demon lord tells the monk to remember to pay back the money he gave him. The monk is sorry, but he can't tell the monk about a time when a ghost was refused entry into the underworld because he was too inferior to enter the three realms. The ghost was bribed to agree to enter reincarnation, but after his fall, he was never able to get close enough to the tower of the lethe to enter. This means that the monk will have to drink a lot of wangchuan to get rid of all his bad memories. This will make him forget all about his old life, and he'll be able to go back to his old self again.
