Pei Guanxue damaged the municipal power grid during the tribulation and owed a huge fine to Heaven. He was forced to work as a takeaway rider and grocery store owner in the modern city. During a takeout delivery, he came across Su Qian, the eldest daughter of a wealthy family who was attacked by a demon who threatened her life. He used modern means of "non-martial arts" to slay demons. Not only did he earn his first merit money, but he also successfully bound Su Qian as his "long-term benefactor", kicking off the process of "working to pay off debts" in the modern city.
