Hidden Vein Genius

The protagonist, Lin Che, was originally the legitimate son of the Lin family of the Tianjian Sect. During a meridians test when he was young, he was judged to be a "waste meridian" and was abandoned by his family to a border town. In fact, he has an ancient "hidden vein" and needs to go through nine tribulations of rebirth and death before he can awaken. His mother, Su Li, came from the hidden ancient clan "Lingxiao Sect" and used a secret method to seal her talent before her death; her father, Lin Wuya, was the strongest sword master of the Tianjian Sect before his disappearance.
