After death, the soul will go to a small town and look for a teahouse. After drinking raw tea, a key will appear at the bottom of the cup. Each soul gets a different key and opens a different door to leave the world. However, Yuan Ji always drinks the cup of tea until the end of the cup of tea. Until one night of the full moon, ghosts and gods use their souls to save Zhong Ji, and Zhong Ji constantly helps other undead souls to make up for their regrets.
Purpose: Self-salvation
