I Pretended to Be a System, and My Pure-Hearted Host Raised a Sickly Genius Doctor

Dan Shiyi, a mediocre nobody at the bottom of the cultivation world, got bound to a System. His mission? Cross worlds and become the "wise old man at her side" for a quack doctor at a traditional Chinese medicine clinic!

As long as he gave the heroine missions that turned her into a master physician, he would earn rewards: [Control over the heroine's body]!

At first, he controlled her for one second and gave her pure, innocent face a hard pinch.

Later, he controlled her for ten minutes as she rampaged through an anime convention, went on a wild figure-buying spree, and kicked a scumbag.

As his control time grew longer and longer, Dan Shiyi started to notice something was off.

Why had the pure, innocent female doctor, once so weak and easy to bully, developed such a dangerous look in her eyes?

"Brother Shiyi, you were sneaking a look at the ladies in stockings by the roadside again, weren't you?"

Yu Chengcheng held a silver needle, her smile sweet and sickly.

"Should I stab my eyes out, so you can only obediently look at me in your mind?"

Dan Shiyi broke down. "System, help! I wasn't raising a master physician. I was raising a yandere!!"
