He is just one of thousands of gatekeepers. He was selected by the ten major sects when he was young. He bid farewell to his parents and left his country and hometown. He could not return to the nine states in the gate whether in life or death. They had no names, and each one was called a gatekeeper. Their bodies were built on the wall to suppress Longhan forever.
But he can travel to modern times. Occasionally, sometimes in the middle of a fight, half of his intestines are pulled out, and suddenly he is in a tall building made of reinforced concrete. He doesn't know what night it is.
There are no monsters here. The outer land has been frozen for thousands of years, and people can live and work in peace and contentment without having to guard the gates. Monsters will also be weakened if they step on the canopy ice wall. It seems that this is the best time.
