Cure.

Shi Lang chuckled as he revealed the truth to everyone. However, not only was Santana shocked, even his teammates shivered when they heard this. Despite your strength, you will still feel the obvious pain if you get hurt. Strength only helped you grow tolerant of the pain and does not make you insensitive to it. 

Today, they saw a boy who could make the pain become ten times more potent, which would render the strength completely meaningless. Shi Lang said, "Now, would you like the medicine to cure you, and shall I operate on you, Doctor?" 

The mask on his face made Shi Lang look very spooky. Even the eyes were covered from the visor glasses. However, the glee contained in his voice made the doctor shiver. He clenched his teeth and said in a muffled voice, "Do what you can. But you will not get anything out of my mouth." 

Shi Lang clapped and said, "Bravo, I admire brave people. Now, let me see where your illness hides."
