Chen Mo was originally an apprentice in a modern antique shop, but when he was cleaning an ancestral bronze mirror, he was transported to a world of cultivation where evil spirits were rampant. Three blood marks suddenly appeared on his wrist, and a cold system notification sounded in his head - he became the most useless "C-grade student" in the Demon Slayer Academy.
Evil spirits rioted in the examination room, and the talismans came back to bite the candidates. At the critical moment of life and death, he suddenly understood the Five Thunder Methods and killed the evil spirits. However, the invigilator's eyes were full of suspicion: "Who are you?"
The bronze mirror can reflect the reflection of the real world, and the system helps him practice quickly, but every time he uses it, the boundary between the two worlds becomes more blurred. There is a traitor hidden in the college, the Taoist family is watching with eager eyes, and there seems to be another conspiracy behind the system...
When the illusion in the mirror gradually erodes reality, Chen Mo must find the truth - otherwise, not only will he die, but both worlds will become a hunting ground for monsters.
