Song Rushi was just a small shady under Black and White Wuchang, but he won many battles due to his good luck. To be ranked according to his merits, he had to wait for the Governor of the Living Hell. However, he was addicted to alcohol and money, and often ran errands after drinking. He made many earth-shattering mistakes, such as using two pages of the Lord of Hell's Life and Death Shop as toilet paper, and pretending that the nourishing soup prepared by Meng Po for the hell leaders was turned into Meng Po soup...
It was the mercy of the King of Hell that he was not punished as a ghost with no chance of reincarnation.
As for Yan Er, in Song Rushi's words, he is just Po Meng's favorite face.
Intention: Harmony, friendship, positivity and kindness
