Traces: District 7

District 7 uses iron and blood to create the "Seven District League", and the geniuses of the six districts are all pawns. Linghu Jinghe is burdened with the mystery of the annihilation of the Linghu family. The powerful combination of the power of recall rules and the power of technology will be the means to clear up all this. Apocalyptic science fiction? Eastern cultivation? The mark is unforgettable, and the direction of the sickle blade is the end of the blood demon and the beginning of chaos!
