Underneath the glorious reputation of the Ouyang family, the supreme martial arts family, "the best in the world", there is hidden a hell on earth called "inhuman". The young boy Chi Wuhan grew up here since he was a baby. His Dantian was destroyed, and he endured the cruel torture of the children of the Ouyang family together with many of his predecessors who were reduced to martial arts experiments. They were deprived of their names, only identified by numbers, and lived in endless pain. However, this hell is also the place where fire is nurtured. The "inhumans", headed by peerless masters such as Wan Jihe, Kong Chonghou, and Hua Wu, integrated their lifelong hatred and martial arts wisdom into their own amazing martial arts, and secretly guided Chi Wuhan to practice the "Qing Ming Jue" and "Huo Xin Gong" that laid the foundation. As dusk fell and the deadline was approaching, the seniors launched a bloody battle at the cost of their lives to help Chi Wuhan escape from death with his peerless martial arts and the fire of revenge. After ten years of dormancy, the red-haired boy emerged from the cave. Carrying the expectations of all the dead and the heinous blood feud, he will use the gun in his hand and the bloody magic to repay the blood debts from the hypocritical family that stands at the top of the martial arts world.
