A plane crash threw He Jin to an isolated island deep in the Pacific Ocean blocked by thick fog. There are no civilized rules here, only monsters and monsters lurking in the darkness - they feed on fear and treat humans as prey and playthings. The island is covered with the skeletons of explorers from the old era.
He Jin was originally just a programmer on the verge of death, but after swallowing a drop of dark red blood from the ancient coffin in the heart of the island, the blood of the ancestor of vampires awakened in his body. From then on, the knowledge and logic of the human world are intertwined with the abilities of the ancient vampires. He has unlimited possibilities for evolution: blood is energy, and devouring monsters can take away their talents. He can also conclude a contract with the source blood and take the ancient beasts on the island as his subordinates.
And this Kirishima itself hides space cracks leading to different dimensions. Divine beasts, monsters, resentful spirits, and even monsters from other worlds are all fighting for control of the desert island. He Jin has no way out - if he doesn't become the strongest, he will only become a prey.
Conquer mythical beasts, hunt monsters, and solve the mystery of the desert island. From prey to hunter, from an isolated island to all realms. What He Jin has to do is not only to survive here, but also to make the entire demon world remember his name.
