From his humble beginnings in the war-torn Mortal Realm, Li Wei embarks on an epic journey to ascend through the Spirit Realm, Core Formation World, and beyond, ultimately aiming for the Divine Immortal Apex. Facing demonic beasts, rival cultivators, and the trials of the Heavenly Tribulation, he hones his qi, masters techniques, and uncovers a cosmic conspiracy by the Shadow Abyss Clan to merge and destabilize the worlds. With each realm, Li Wei grows in power and wisdom, forging alliances, battling enemies, and confronting his inner demons. His quest to unify the Nine Worlds and transcend mortality weaves a saga of courage, betrayal, and the pursuit of the ultimate dao.
