Poisonous Gu Immortal Lord

The good-for-nothing prince accidentally obtained the Gu Sutra and started a journey of cheating: Is the foundation destroyed? It's okay, I have Gu skills, let's reshape it; is the princess sick? It's okay, I know how to use Gu medicine to cure all diseases; what, the treasury is empty? It's okay, I have some elixirs, so I'll sell them for emergency first. In the eyes of his allies, he is the God of Gu, "The God of Gu makes people die at the fifth watch, how dare the King of Hell scream at the third watch"; in the eyes of his enemies, he is Yama, "the Hell of the dark night, poisonous Gu seduces the soul"...
