Pain.

Shi Lang recovered from the pain and took an hour to do so. He asked, "Instructor, can we start again?"

Yuu glanced at him from behind her bangs and said, "Only if you are ready to take it."

Shi Lang nodded and climbed up the simulation chair again. Yuu glanced at him and nodded slightly. The pain he suffered inside the simulation was not a light thing. The amputating sensation was transmitted to his neurons directly and then to the brain. The intensity was manipulated to twice that of the original pain.

Shi Lang was not aware of this. This was the training, the higher the pain the more a person tries to avoid it. The boy was not weak, but Yuu was too strong of an opponent for him to deal with. He had no idea how to stop her once she started using her strength. He had tried everything that he could even the skills and knowledge of his old life did not come in handy to him.
