Weird Invasion: I Can Use Fear to Kill Ghosts!

[Anti-routine ghost killing + anti-routine system + time travel + no cp + online IQ + non-traditional supernatural + non-traditional routines] Gu Yongzhe traveled to a strange invaded world called Blue Star. But he didn't expect that as soon as he traveled through time, he would witness a scene where his whole family was brutally eaten by ghosts. He thought he was hiding it well, but in the blink of an eye, the ghost bride who had eaten his whole family came face to face with him with her pale and cold face! Ghost Bride: hello! Gu Yongzhe: Don't come over! Just when Gu Yongzhe was about to be played to death by the ghost bride, the system finally appeared. After being bound to the system, Gu Yongzhe, with the full help of the Ghost Bride, successfully used the fear and "mere fatal injuries" caused by the opponent to kill him. The dead ghost bride said: Well, that's it, I have no objection! But Gu Yongzhe discovered that his system seemed different from ordinary systems. The full name of his system is: Ten Thousand Times True Damage Return System. System: The more fearful the host is and the more serious the damage it receives, the more terrifying the real damage returned will be. Gu Yongzhe: You cheater! Why don't you look at other people's systems? I won't be able to live! System: It is determined that the host is trying to 'maliciously speculate' on the system and interfere with the system's judgment. The system will formulate a corresponding punishment plan... Gu Yongzhe:... From then on, Gu Yongzhe used this anti-routine system and anti-routine method of killing ghosts to wander around places where ghosts frequently appeared. Through the fear and harm caused by the ghosts to him, he successfully hunted one ghost after another.
