The Ethereal Heavenly Dao

Born of Heaven are the Four Fates; nurtured by Earth are the Seven Ways. Heaven's will cannot be defied; the Dao follows nature and gives life to all things. When the Four Fates have yet to emerge and the Seven Ways are about to arrive, that is the Heavenly Dao. After cultivating bitterly for hundreds of millions of years, the Hollow Spirit Emperor, said to rival the Four Great Ancestors, severed his cultivation. His soul lamp went out, and he vanished from the Four Heavenly Fate Realms. No one knew where he had gone. At the very moment the Hollow Spirit Emperor died and his Dao dissipated, Li Zhiyi was born in a small world in the universe. (The protagonist is cunning, with no System, a humorous tone, reborn as himself, and an imaginative fantasy setting. The blurb is nothing special.)
