Ling Che, a cold researcher, was accidentally bound to the "Historical Soul Guardian System" to slay demons, eliminate evil spirits, unlock the skills of historical figures, and level up by relying on points. While investigating fictional historical relics, they met Su Yan, an independent archaeologist. The two teamed up because they had the same goal, but they attracted the green tea villain Bai Weiwei (Ling Che Qingmei, Love But Not) to secretly create a stumbling block. There were also evil demons who coveted the power of the relics, and evil supernatural beings who robbed the system. Ling Che crushes his opponents with his system, and Su Yan breaks prejudices with his strength. The two gradually develop a tacit understanding as they upgrade to slay demons, and the secrets deep in the ruins are pushing them into a greater crisis.
