This book has no female lead! Only the protagonist's father has a wife.

Ksitigarbha made a vow: “I will not become a Buddha until Hell is empty.” Then he fell into a deep sleep. His vow led to the collapse of the underworld, and the Ten Halls' Fengdu Emperors also exhausted their magic and fell asleep to restore their souls and powers. The Dongyue Emperor transformed himself into the Dao and reincarnated into the Li family of Jixi as the son of its richest man. See how everyone will revive the underworld, and discover who is pulling the strings behind the scenes in an attempt to plunge the Three Realms into chaos.

When I chose the categories, I never thought the book would get a contract. This isn't a story with just one protagonist, because everyone in the world is the main character in their own right. So it isn't told entirely from Li Dabai's perspective.
