Urban Legend: the Ghost-Slaying God from Grandfather and Grandson

The young man's name is Hua Liang, and his grandfather likes to call him Ah Liang. The old man's name is Hua Jin, and his grandson likes to call him Master Jin. This is an old man who always likes to talk nonsense, and this is a young man who always likes to follow the old man. The gods and ghosts are greedy and wantonly toy with all living beings. The old man often says that people should always do something in this life. My grandfather and grandson came from nowhere, and not much is known about them. I just know that they haven't seen ghosts and gods for a while! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
