Changsha, the twenty-eighth year of the Republic of China. The layout of the nine gates has been determined. The upper three gates are in charge of one side, the three flat gates are licking blood, and the lower three gates are turning clouds and rain. Zhang Qishan is in charge of the Nine Gates, the February Red Stage is not cold yet, Half Li is suspicious by nature, Chen Pi Ah Si is unruly, Black-backed Sixth is a loner, Jie Jiuye is strategizing, and Qi Tiezui is a master of Dunjia. Wu Laogou took over the Wu family at the age of twenty-one, and had an old grudge with Zhang Qishan over his brother's execution. Huo Xiangu was twenty years old and supported the Huo family alone. The side branches were eyeing her, her aunt secretly communicated with foreign enemies, and civil strife was about to break out. A box made of pig iron was dug out from under an abandoned warehouse on the outskirts of Changsha. It is welded on all sides and cannot be pried open, sawed or exploded with explosives. There is a living thing in the box, which vibrates like a heartbeat every two hours. Qi Tiezui's compass spun wildly. No matter how he placed it, the box always pointed in the same direction - the mine. At the same time, a landslide occurred deep in the mine. Under the No. 7 Tunnel, a stone tablet engraved with ancient characters was revealed. There were six words on the tablet: "Daughter of the Huo family, open this door." Upon hearing the news, Huo Xiangu entered the well, and Wu Laogou followed closely behind him with his hunting dog Three Inch Nails. Under the stone monument, a meteorite well that had been sealed for thousands of years was revealed again. The walls of the well are engraved with spells that no one can understand, and there is a sacrificial vessel made of meteorite copper sealed at the bottom of the well - it is said that this object can connect yin and yang. Living people can see the dead when they touch it. If a dead person touches it, I don't know what will happen. And every time the sacrificial vessel wakes up, it needs the blood of a daughter of the Huo family to comfort it. Wu Laogou and Huo Xiangu, one is responsible for the blood feud of his brother, and the other is responsible for the internal strife in the family. They walked side by side in the darkness deep in the mine, relying on each other in the desperate situation under the meteor shaft.
