Who is the manipulator behind the scenes? Who will be resurrected? Gu Qiqi, who thought he was a rookie, did not expect that he would be given the task of killing the Demon Lord. For the sake of his own life, he had to accept it and embark on this difficult path of cultivating immortality. The heroine is a bit funny, has a charming physique, and turns danger into good fortune along the way. It contains a lot of private information, please don't use it.
