He Bao Dao Fa, Wo Yi Dao Yige

Special Forces soldier Jin Quan is betrayed during a mission and becomes a living target for guided missiles. When he regains consciousness, he finds himself as a destitute man collapsed on the streets of the Lower City—a slum where the world’s lowest class of humans gather, living as cannon fodder in the mines. At this critical moment of life and death, Jin Quan awakens to the class of Demon Swordsman, and the radiation from the dirty bomb explosion in his past life becomes his innate talent. In this world, Jin Quan will engage in a fierce battle against the Chosen Ones. (Source: KuaiKan, translated)
