The moment night shift security guard Lin Zhaoye drew his sword, the whole city rioted with supernatural beings. Under the blood moon, all powers receded like the tide - only where his blade was directed, all powers surrendered. And the silent Jiang Zhiyao beside him, whose life experience he never talked about, was actually the source of this supernatural collapse. When the government sealed the city, hunters launched a siege, and the underground supernatural organization vowed to kill the two, they realized that Lin Zhaoye's knife was not a weapon, but a seal; Jiang Zhiyao's silence was the final atonement. Now that the seal is loose, the world is disintegrating, and they are the only key and the only sacrifice.
