The Supreme Demon of the Demon Realm has cultivated for ten thousand years and reached the Great Perfection of the Tribulation Transcendence realm. He is just one step away from entering the legendary Immortal Demon realm. Cold, ruthless, and decisive in slaughter, he regards all living beings as ants and believes in absolute power and equivalent exchange. His demonic might shakes the heavens and myriad worlds: with a single thought, he can send stars crashing down; with a single palm, he can cover countless worlds. At the most crucial moment of his Nine Heavens Annihilation Demon Thunder tribulation, his sworn enemies join forces with his inner demon to launch a surprise attack. Though he fights hard to kill his attackers and suppress his inner demon, he is gravely wounded. His physical body is nearly destroyed by the strongest bolt of tribulation lightning, and his soul is severely damaged, on the verge of vanishing. He is detected and bound by Subsystem No. 007, belonging to the “Myriad Worlds Grievance Compensation System,” and thus begins a journey through the Myriad Worlds.
