Qin Yun, the Crown Prince of Great Qin, lived in seclusion in a small town. For ten years, his wife Su Wanli was actually an undercover agent for the Qingyun Immortal Sect, who brutally dug out his innate sword bone. In his near-death state, Qin Yun awakened his Supreme Bloodline and destroyed the Qingyun Sect. After taking revenge, he gave up claiming the imperial throne and re-establishing the nation, instead spreading the Mortal Dao, allowing ordinary mortals to practice swordsmanship and protect themselves without spiritual roots, thus breaking the shackles of inequality between immortals and mortals.
