Lin Ye, the owner of a second-hand bookstore next to the university town, was struggling with the rent increase when he found a snake-shaped brass badge in an old book. That night, Lao Zhang, who was collecting scraps, floated through the air. A giant horned skeleton was discovered in an abandoned factory. A mysterious man stared at him with vertical pupils and said, "Your bloodline has long been exposed."
The ever-decreasing countdown on his cell phone, the gradually alienated neighbors, and the note in the book "When the blood moon rises, when the dragon skeleton awakens", he is involved in a secret that spans thousands of years - there is a sealed ancient dragon buried under this land, and he is not an ordinary human being, but a descendant of the "Watcher" who can awaken the dragon skeleton and suppress it.
When the neighbors on the street turned into unconscious sacrifices, and the "awakeners" led by the windbreakers pressed forward step by step, Lin Ye had to find out in six days: What is hidden in Aunt Wang's ancestral black medicinal powder? Why does Lao Zhang's deformed body resemble dragon scales? Could his strange illness during the summer solstice be a sign of the awakening of the dragon bloodline?
Before the blood moon hangs in the sky, he has to make the most difficult choice between saving the world and being swallowed by his blood. And behind the fighting around the dragon bones, there seems to be an older conspiracy hidden - the so-called watchers and awakeners may have been on the wrong side from the beginning.
