Sixteen-year-old boy Li Qing has been practicing martial arts with his master in the mountains since he was a child. Until he was seven years old, a dying stranger brought a mysterious treasure box and predicted that a biochemical crisis would break out in Jihua City nine years later. Now, he has inherited the unique skill in the box "Nine Yang Burning Heaven Skill" - the most powerful internal power, which is specially designed to defeat the fusion of machinery and flesh and blood. When he first entered Jihua City No. 4 Middle School, Li Qing soon discovered that the campus had been infiltrated: the mechanical eyes of the teacher in the Academic Affairs Office, the mechanical monster in the basement, the flame pattern totem of the mysterious classmate... When the biochemical crisis really broke out, he must fight against the mechanical craze with his flesh and blood in this steel jungle...

Li Qing, a high school student, accidentally got a watch, and his life became colorful from then on.
