In his previous life, he was plotted by a scumbag and a bitch, and died tragically in the cold palace. After being reborn, he comes with the "Voice Broadcasting" skill, which broadcasts all inner OS full-screen and 8K high-definition to the surroundings. After hearing this, the scumbag man and scumbag woman want to become a monk on the spot.

- The core of the cool point: the female protagonist complained about the male protagonist's family eight hundred times in her heart, but she had to kneel down and salute on the surface; while the male protagonist thought she was docile and weak, in fact, she had already formulated the "KPI for seizing power and revenge" in her heart. Falling in love and killing each other, evenly matched.
