My Family Has a Weird Carmen

Yin and Yang coexist in all things, and so does the world. Human beings live in the Yang world, while monsters roam the Yin world. What connects the two worlds of Yin and Yang is a special existence - the door. According to legend, there are three types of gates: Heaven Gate, Earth Gate, and Human Gate. Its human gate has disappeared for a long time, the earth gate is connected to the underworld deep in the earth, and the heaven gate... Is condensed by a group of people called Tianmu masters. But for Yu Changqing, something seemed wrong with the development of things. Because there was a monster stuck in the door he condensed out of.
