According to folklore, the seventh month of the lunar calendar is the ghost month, where yin energy is at its strongest. People born in this month have very little yang energy, and some people can even connect yin and yang. People born in July and a half have the most yin energy and are most likely to attract dirty things.
People who can connect yin and yang are called Yin Bridges, connecting the two realms of yin and yang.
It is said that a person with a special destiny is destined to the underworld when he is born, and he is born to serve the king of hell in the underworld. It is said that such a person does not appear once in a thousand years. Once he is born, he will be accompanied by visions. Such people are called "yin people" and "living ghosts".
The young Zhong Lingxue unfortunately became an orphan. On a night in July and a half, a man who called himself Wang Xueli came to her door and gave her a dagger. Someone adopted Zhong Lingxue the next day. From then on, Zhong Lingxue took the shadow in the dagger given by Wang Xueli and became the agent of the underworld in the human world.
The wishes that living people cannot tell or fulfill are the thoughts of the dead. Only by cutting off these thoughts can they be sent to the underworld. What Zhong Lingxue has to do is to send the dead souls to reincarnation and the evil ghosts to purgatory.
