How to Know the Devil

In Wan Zhang Valley, there was a young boy named Li Zhiyan. The reason why he was named like this was because when he was born, there was a note. There were only eleven words in the note, "You can correct your mistakes if you know them. There is no great good, Li Zhiyan." It's just that this is obviously a swaddled baby. Why are there such admonitions for him? Is it true that someone is born wrong? Is it this person who is wrong or this thing that is wrong? With confusion, the young man steps into the world to find the elusive answer. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
