The 16-year-old Xie Han was supposed to die like this, but at the last moment of his life, Wan Yang appeared and signed a contract with Xie Han, turning Xie Han into an immortal [law enforcer]. When human beings' desire for something exceeds the maximum limit of the container [human], it will become [hunting], and the [law enforcer] exists to eliminate these [hunting]]. Regardless of whether it is [good] or [evil], [hunting] is not allowed to exist in the world of common sense, even [enforcers] are the same. Their existence is just a [non-common sense] group used to deal with another [non-common sense] group to maintain the normal operation of the [common sense] world. Xie Han always thought that Wan Yang was the one who gave her new life, but only Wan Yang knew that he had never played the role of a savior.
