When he was about to succeed, the darkened villain actually followed him back. Looking at the high school student's face, he held her in his arms with one hand and said in a dangerous tone: "When I think that I can possess you at the age of eighteen... I even want to... Kill myself..." "Yangyang... I have been looking for you for so long. This time, it is you who will go to hell with me." Ah bah! Later... The Space-Time Management Bureau has a new boss.
