Shen Duqian's practice is stuck. Master said: Your Taoist heart is too pure, so you have to go hang out among people. So he put on delivery clothes, rode an electric bike with Shiba Inu stickers, and became a delivery rider running around the city. The first order was delivered to a gloomy old house. There was a black cat squatting in the courtyard, with golden eyes, evil spirit, and a bad temper. The first thing he said was: "My name is Ye Chen, not Xiao Bai." One person and one cat went from confrontation to alliance, from the resentful soul in the ancient well to the evil cultivator in the mass grave, from the take-out box to the lightning disaster. Shen Fengqian crosses the dead souls, accumulates merits, breaks obsessions, and sharpens the Taoist heart in the fireworks of the world. Ye Chen had been guarding the lonely house for three hundred years, and finally waited for someone who was willing to accompany him to find his way. This is a story about bottlenecks, breakthroughs, partners and destination. The world of mortals refines the heart, and cats follow the same path.
