Wang Qinghe, a disciple of Shuiyun Temple who had gone down the mountain to practice, transformed into a delivery rider. He relied on Shuiyun Jue's mental skills and spiritual consciousness to predict road conditions and became a "humanoid plug-in" at the site. When he was going to deliver an express order to his old apartment, he was ambushed by a demon in the corridor where the power was cut off. He then showed his magic skills and forced out a desperate hamster spirit. This once-pet rat spirit lived a miserable life after being abandoned. It asked to be taken in on the condition of providing information about the city's spiritual practice community. Wang Qinghe took it into his pocket out of compassion and started the immortal rider's journey of urban practice.
