Xuanhuan: I’m Harmless, but the System Forces Me to Turn Evil

(I'm no good at writing introductions. Please read the story.)

After dying as a street thug, Mu Tian transmigrates to another world and becomes the apprentice of an elderly doctor in a small village.

He obtains a prankster System. As long as people think he's not a bad person, he gets a mission. The mission is to do something bad to someone who believes he's not a bad person, without getting caught.

Old Doctor: “Good apprentice, do you know that saving Zhang Suzhen could put your life in danger?”

Mu Tian: “As a doctor, it's my duty to heal the sick and save lives. I'm willing to give my life for it!”

With tears in his eyes, the old doctor said, unable to bear it: “Good! Your master supports you! Then hurry to your room and consummate your marriage!”

System mission reward title: Century-Old Doctor, Specialist in Bullshit.
