Intro. In the middle of the city of Lanzhou, which glows day and night, there is a small "shipper" that few people would expect to be a legend living in the human world. His name is DouDou, or affectionately known as Dau Dau. On the surface, DouDou is just a short young man, 1m4 tall, weighing 45kg, with a bright face, mischievous smile and clear voice. But behind that childish appearance, he is a black cat Taoist who has lived for more than six thousand years, traveling all over the world, suppressing demons, saving souls, and maintaining the balance of yin and yang.
After thousands of years of cultivation, DouDou was tired of endless wars so he chose to hide in modern times. He bought an apartment in the most luxurious apartment building in Lan Chau city, the upper floor is full of wind and clouds, where the window opens to the vast sky. That place is both a home and a secret shrine — filled with antiques, spells, and auras that ordinary people cannot perceive.
To blend into the human world, DouDou used magic to transform his identification documents, making all inspection systems recognize him as a normal person.
