Lin Feng, the former crown prince of Great Xia, is ambushed on the battlefield, leaving his dantian shattered and his cultivation completely destroyed. Suspected and distrusted by his imperial father, he is stripped of his title and banished to the barren city of Qingfeng. At the brink of despair, he awakens an impurity-extraction system capable of removing flaws from all things. He repairs his own body, forging a perfect sacred physique with a hundredfold cultivation talent, while purifying cultivation techniques, pills, and treasures. Together with his younger sister, Lin Xi, he establishes the Yanyun Pavilion and stirs up Qingfeng City, subdues exotic beasts, commands multiple spiritual flames, and ventures into secret realms to seize the Primordial Desolate Battle Stele. After a life-and-death battle with Zhou Chengfeng, a powerhouse on the Martial Emperor Rankings, he rises to godlike fame and claims the top position on the rankings. Wielding the Black Tower of Time, he navigates the struggles between the imperial family and the major sects, shaking the Northern Region with his auctions as he grows from a deposed crown prince into an unparalleled powerhouse.
