A conspiracy and frame-up made Qin Xiao a wanted murderer.
On the way to escape, he was sold into a drug den in Myanmar and became a slave.
Here, he endured to survive, worked hard to practice his skills, and gradually climbed to the position of drug lord's henchman to escape from this place.
Until he discovered that this drug lord was the culprit who killed his parents back then.
Until the Long Kingdom police came secretly and handed him a top-secret file:
"Qin Xiao, your father is our best undercover agent. Now, we need you to take his place."
From wanted criminal to undercover, from abyss to light.
"Dad, Mom, the road you haven't finished yet——"
"I'll go down for you."
