Xin Fengchen was originally an ordinary programmer plagued by overtime work and insomnia. That is, until the night of the full moon, when a fatal drug deal awakened the dormant blood in his veins. His wounds healed at an extraordinary speed, his senses became as sharp as a beast's, and an unfamiliar, violent power surged through his body—he was no longer human. The appearance of Zhong Yunshen, a mysterious old man, uncovered a shocking family secret: he is a descendant of the ancient wolf clan, and the car accident that claimed his father five years ago was actually a carefully plotted murder. Meanwhile, the senior management of his company cast scrutinizing glances at him. Behind the seemingly ordinary personnel changes, there seemed to be prying eyes watching for his "non-human" identity. The ordinary world cracked open, and Xin Fengchen was forced to step into a bizarre shadow world. On one side was his uncontrollable wolfish instinct; on the other was the illusory normalcy of urban life. As the upcoming new moon night approaches, he must make a choice: suppress his true nature and return to "normal," or embrace the power of his bloodline, uncover the truth under the Covenant of the Moon, and avenge his father?
