The Cliché Story of Killing His Wife and Becoming Enlightened

I accompanied him through hardships and hardships, and he cultivated from a poor boy to the best in the world. It turned out that this man who had killed a thousand swords believed some nonsense about "killing his wife to prove enlightenment". In order to ascend, he stabbed me with a sword. After I died, he didn't become an immortal, but went completely crazy. But I am not dead. The world of immortality is too dangerous, and it is most comfortable to live a stable life in the mortal world. Now the whole world is asking me when I will kill him. I prefer not. Death would be too easy for him. I want him to watch his sect, his reputation, and everything he cares about, rot away bit by bit. I want him to kneel before me and admit with his own lips that he was wrong. But when the natural disaster that destroyed the world came, this bastard was about to lose his soul just to save me... I clutched the knife. Will I avenge this revenge?
