The protagonist, Lin Feng, was once the ace sniper of the special forces unit “Blade.” After an accident during a mission, where he broke regulations to protect a teammate, he was forced to leave the military. Bearing a body covered in scars and secrets no one knew, he returned to a bustling yet unfamiliar city. He tried to conceal his identity and live an ordinary life, but after a chance act of bravery, he was drawn into the city's undercurrents: business rivalries, criminal gangs, and old enemies on his trail. With no choice but to take up his “weapon” again, he struggles between the rules of civilian life and a soldier's principles, all to protect those around him.
