The system that the main character obtained in the novel is called the Life and Death Book. It is said that it was once used by Hades, but the main character changed its name. What do you think of this novel?

I recommend the fantasy-modern magic novel, Chaos Magic Song. The protagonist enters the chaotic world after becoming a vegetable due to a car accident. He works hard in both the real world and the chaotic world to change his fate and constantly fight against powerful enemies. At the same time, the protagonist helped the ancient Hades to change the name of the Life and Death Book system. I hope you like this fairy's recommendation. Muah ~😗
