Ai Yu Sha Yi Zhi Ye

A former hit-man, once at the top of his career, was severely wounded while attempting to rescue an alpha child a decade ago. The injury left him unable to perform as he once did, prompting him to leave his past behind and live under a new name in the countryside. His quiet life is disrupted when a visitor arrives unexpectedly. The man he saved as a child has now grown into a gang leader and seeks him out with intense motives.
