Boundary Keeper: I Kill Demons and Guard the Human World with My Ordinary Heart

A mountain climbing trip, a heavy fog, and a mountain range that did not exist on the map - Jie Shan, completely changed my life. This is the last barrier between the human world and the demon world. There are monsters in the fog, there are monsters outside the mountains, and there is a monster king in the depths who is about to break the seal. And I, Chu Yao, Chen Mo, Lin Wan, and Jiang Che, five strangers, were forcibly given the same identity: Boundary Keeper.
