Lin Yi is a young man with extremely high talent in martial arts, but he has a low-key and introverted personality. He doesn't like fighting and prefers to study martial arts and medical skills. His girlfriend Su Waner is his childhood sweetheart and his only weakness.
However, in order to obtain a precious martial arts secret book, Su Waner betrayed Lin Yi and teamed up with a young master from a martial arts family to frame him until he was seriously injured and expelled from the school.
Fortunately, on the verge of life and death, Lin Yi accidentally triggered the mysterious system in his body - the "Reincarnation Technique" and returned to ten years ago with memories and experiences from his previous life.
