MTL - The Last King of Darkness - Chapter 473 invincible

The Special Investigations Unit is a covert organisation that no-one in the city knows about, dedicated to investigating bizarre occurrences beyond the comprehension of the living. The Chief Zhao Yunlan isn’t a simple guy either, being the inheritor of the Guardian Order, he has always been a righteous conformist, excelling between realms of the living and the dead. While investigating a school suicide case, Zhao is attracted to the calm and reserved Professor Shen Wei, but the Professor seems to be rather fickle towards him…

- Description from Novelupdates

The human Race is at war with the Vicious Dalki and when they needed help more than ever, THEY started to come forward.

Humans who had hidden in the shadows for hundreds of years, people with abilities.

Some chose to share their knowledge to the rest of the world in hopes of winning the war, while others kept their abilities to themselves.

Quinn had lost everything to the war, his home, his family and the only thing he had inherited was a crummy old book that he couldn’t even open.

But when the book had finally opened, Quinn was granted a system and his whole life was turned around.

He completed quest after quest and became more powerful, until one day the system gave him a quest he wasn’t sure he could complete.

"It is time to feed!"
"You must drink human blood within 24 hours"
"Your HP will continue to decrease until the task has been completed"

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.
