Under the neon lights of bustling cities, there are countless unknown evils and spies - the repeated sound of high heels in office buildings at midnight, babies crying late at night in rental houses in old communities, the endless empty seats in the last train of the subway, the strange black shadow at the door of the hospital morgue... These are not legends or hallucinations, they are resentful spirits lingering in the world, evil things doing evil, hidden dangers forgotten by the yin and yang order.
Lin Chen, a seemingly ordinary urban youth, is actually the last descendant of a hidden Yin and Yang family. He bears the ancestral Yin and Yang Seal and can understand Yin and Yang, distinguish evil spirits, and perform secret arts. Three years ago, his family was plotted by a traitor, and his parents died tragically in mysterious circumstances. He was forced to hide his name and hide at the bottom of the city, pretending to be an ordinary office worker, just to find the truth about the family's destruction and kill his enemies with his own hands.
In an accident, he was forced to take action, using a simple spell to kill the evil spirit. Unexpectedly, his strength was exposed, and he was also involved in the whirlpool of the city's Yin and Yang world - the mysterious Yin and Yang Administration Bureau, the evil sect that covets the Yin and Yang Seal, the demons and monsters lurking in every corner of the city, and the traitors who betrayed the family in the past have all surfaced.
From then on, Lin Chen no longer hid, and walked between the yin and yang of the city in the name of yin and yin. Killing evil spirits in office buildings, eradicating evil spirits in old communities, suppressing evil spirits in hospitals, and controlling evil spirits in subways. Every time you take action, you can gain opportunities and improve your strength; every time you break the situation, you can uncover a layer of truth and slap Xiaoxiao in the face.
He possesses the secret skills of yin and yang and holds the yin difference token in his hand. He can suppress evil with spells and eliminate evil spirits with magic. He can also deal with the forces in the yang world and fight against the evil spirits in the yin world. From a low-level clerk to a legend in the urban yin and yang world
