I'm Guarding the Yin and Yang in the Old City

Chen Yan is twenty-four years old and guards a daily grocery store alone in the old streets of the old city. At the age of sixteen, he went to the city to make a living, taking on jobs that others shunned, such as cleaning cemeteries and taking care of abandoned old houses. He was always accompanied by a cold and evil atmosphere. He can sense the evil spirits wandering in the world, and ordinary wandering souls dare not approach him. But he always thought that it was just because of his own fate and never got into the reason. A piece of mysterious jade that he has worn since childhood is hidden close to his body, and he must abide by the three precepts: hide his clumsiness, avoid trouble, and never enter the mountains. The peace lasted for three years. A cold rain broke the tranquility of the old street. The faceless woman holding a black umbrella came from the mountains, evil spirits spread into the city, and the wild ghosts wandering the streets fled in all directions. Strange incidents followed one after another and swept through the old city. Dust-covered haunted houses, resentful rivers, and evil spirits disturbed and bred by the mountain air appeared one after another. A rumor came to my ears: deep in the mountains, I have been looking for him. Chen Yan has no knowledge of the magic of talismans and has no magical power to exorcise ghosts. He only relies on past experiences, ancient artifacts, and the weather and terrain to deal with difficulties. As the seal in the mountain continues to loosen, the evil spirits entering the city become stronger and stronger, making it difficult to walk alone. The descendants of the guardian who were hiding in the market, the remaining old spirits in the mountains, and the strange people who knew the ancient secrets appeared one after another, and they teamed up with him to explore the truth. On one side are the fireworks in the city, on the other side are the eternal haze of the mountains. Forced to step out of the shop, Chen Yan will eventually understand that he cannot avoid his fate. One city observes strange things, and one body guards Yin and Yang.
