Ji Ming once traveled through time and became the young patriarch of the strongest onmyoji family in the island country, but he was reduced to a "waste" because he could not inherit his original master's status. In order to protect his position, he was forced to take on a dangerous mission, but he discovered a shocking conspiracy - the ghostly man-eater was actually the plot within the plot, and the mastermind behind the scenes wanted to use the knife to kill people!
At the critical moment of life and death, the domineering system awakens, forcing him to do whatever he wants: forcibly taking a fierce ghost as a servant, losing his virginity for two lifetimes, suppressing the family's forced marriage, and even getting a glimpse of his father's mysterious ghost...
The yin and yang plots are intertwined. Ji Ming not only wants to kill all the evil spirits, but also has to beware of the hidden arrows of his relatives. When the domineering value is ignited, can he tear through the hypocrisy of the family, step on the mountains of corpses and seas of blood, and aspire to the top of Yin and Yang?
