With his mother critically ill, Lin Yuan signed a life-and-death contract to go to the island and become a lighthouse keeper. The monthly salary is one hundred thousand, but it is extremely bizarre: the previous lighthouse keeper turned into coral bones, rabbits eat meat, wild boars become spirits, and at midnight all beasts bow toward the center of the island. To survive, Lin Yuan swallowed the blood and flesh of exotic beasts raw, awakening immense strength, nirvana, and the weapon master ability all the way. Yet he did not know that this island is a testing ground sealing world-extinction-level bizarre entities, and he is the purifier chosen by mistake. Three months later, when he went down the island, the whole world panicked: that lighthouse keeper had eaten himself into a world-extinction-level calamity.
