Weird Invasion: I Can Use Fear to Kill Ghosts!

[Weird invasion + anti-routine ghost killing + anti-routine system + time travel + no cp + online IQ + non-traditional supernatural] Gu Yongzhe traveled to a strange invaded world called Blue Star. But I didn't expect that as soon as I traveled through time, I would witness a scene where the whole family was brutally murdered by ghosts. He thought he hid it well, but in the blink of an eye, the ghost bride's pale and cold face came face to face with him. 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. But Gu Yongzhe's system seems to be 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 take a look at other people's systems? I can't live! System: It is determined that the host maliciously speculates on the system and attempts to interfere with the system's judgment. The system will formulate a corresponding punishment plan. Gu Yongzhe…. After being bound to the system, Gu Yongzhe, with the full help of the Ghost Bride, successfully used the fear caused by the opponent to him and the mere fatal injuries to kill the opponent. From then on, Gu Yongzhe used this anti-routine system and anti-routine ghost-killing method to wander around places where ghosts appeared, and successfully hunted one ghost after another through the fear and harm caused to him by the ghosts.
