It is said that those who do not want to forget their previous lives or be reincarnated can jump into the Wangchuan River and suffer the pain of Wangchuan. Then they will not drink Mengpo soup, reincarnate, or forget their past lives.
In recent years, for some unknown reason, the number of ghosts jumping into the Wangchuan River has increased year by year. Those who can't bear the pain of the Wangchuan River will not even be able to become ghosts in vain.
Therefore, the underworld opened a new task this year, and the King of Hell assigned this errand to Po Meng. Anyway, she is close and can be easily managed nearby. What to do? Eliminate the obsessions of those who are obsessed with jumping into the river, and let them reincarnate willingly.
Su Meng's new assistant, Meng Po Tang, didn't care about this job and threw it to Su Meng, so Su Meng became a cleaner on the Wangchuan River.
