Lord of Ten Thousand Realms

Lu Chen, an orphan abandoned by fate, awakens the Ten Thousand Realms Death Lord system on the brink of life and death. This system does not teach him to cultivate immortality or become a god, but instead has him harvest the souls of the dead across myriad realms and rule over the underworlds of all heavens! From paranormal events on Earth to fallen god-kings in the celestial realm, abyssal lords in the demon realm, and mechanical undead in the tech universe... Every death in every world is his nourishment; every soul is his subject. While all living beings in the myriad realms pursue immortality, he is already the end of all life.
