The two realms of yin and yang depend on each other and benefit each other.
The division of forces between the Yin and Yang Realms changes:
The Yangjian is a Daofa clan headed by the Mu clan Onmyoji and supported by the four major Onmyoji families; while the Yinjian is dominated by the two ghost kings who claim the throne, and the Yinjie that runs through the two ghost kings coordinates without hindering their power.
Person in charge of the human world: Mu Qingyu, the 19th generation descendant of the Mu family
Person in charge of the underworld: Yan Xu, the boss of the underworld
Mu Qingyu's Taoism and Dharma are naturally integrated. A peach wood sword and a few yellow talisman papers drive away the centuries-old ghost in the ghost house. Yan Xu, half Buddha and half ghost, washes away the underworld with one person's power.
Their strength is particularly powerful, and they are all young people who cannot be underestimated.
On the fifteenth day of the seventh lunar month, the Ghost Festival, the gate of ghosts opens wide, and all the ghosts in the underworld can take a walk in the upper world. After all, something went wrong during this half-day trip to the underworld. Two-thirds of the ghost missions in the underworld were on duty to check the security of the Mid-Autumn Festival. An evil ghost took advantage of the loophole and stole a book called "Returning to the Soul" that had a sense of time. It also released all the ghosts in the book, causing disasters in the underworld.
Mu Qingyu is the person in charge of protecting the human world, and Yan Xu takes the initiative to take responsibility for his mistakes, and the two work together to start a journey of collecting souls and rewriting "Returning to the Soul".
