Song Lin, the eldest grandson of the Song family in Beijing, had high hopes from his elders since he was a child, and worked hard within the system. He is as gentle as jade on the surface, impeccable in his dealings with others, and is the perfect young man in everyone's eyes. However, a sudden prophecy pushed him into the abyss - he was actually the "son of the prophecy" sealed by Taoism thousands of years ago, and was responsible for suppressing the demons and monsters in the world. As the seal loosened, demons from all walks of life swarmed in, either coveting his flesh and blood, or trying to take advantage of his prophetic power. Song Lin was forced to get involved in this battle between humans and monsters, and gradually sank in the quagmire of power and desire. He began to discover that the so-called "chosen one" was just a chess piece. Under the gentle mask, a cold and calculating heart was awakening. When the demon's blade approached, and when the high-level game regarded him as an abandoned son, Song Lin chose a path that no one expected - since the world wanted to use him, he had to become the rule itself, even if he became a more terrifying existence than the demon.
