Ning Yechen used to be the Demon Lord. He singlehandedly took over the Demon Realm and attacked the Heavenly Realm. His name preceded him throughout the Six Realms. He got tired of fighting, so he quietly went into seclusion and became a happy hermit.One night, an Empress from the Heavenly Realm fell into the Mortal Realm after someone drugged her with an aphrodisiac. She inadvertently fell into his room, and they made out. After the deed, the Empress quietly left. Just when he thought he would never see her again, she showed up in front of him ten years later, bringing a child, saying it was his daughter and demanding accountability from him! “She’s your daughter. You have to be responsible for us!” Ning Yechen was stunned!

On the wedding night, she was tied to his bed.

Sullo was transmigrated to a world of High Gods. The people living in the world could light the God flame by condensing their believers’ faith to expand their god realm, forming their own religion to become a high god.

The god realm could be grown indefinitely by having more followers and absorbing their faith. A follower’s strength were closely tied to the gods they followed as well. However, unlike other gods, Sullo had a unique thousand-fold amplification system that made everything grow at a thousand times of their original speed.

A normal tree spirit had evolved into a World Tree that would expand his divine domain.

A normal water snake had evolved into an ouroboros that would protect his divine domain.

A normal behemoth had evolved into a golden behemoth that would lead the attack on other domains.A normal angel had evolved into a 12-winged archangel that would gladly sacrifice for their god.

A normal elf had evolved into an elf queen that could heal anything…

Years later, as the other gods were still waging wars to gain control of the gnomes and dwarves, Sullo’s followers were already as powerful as other gods.
