In the midst of the conversation, the thing that caught him by surprise was the other matter that Yun Yang had mentioned.
"You'll help me heal? In three days?"
Shi Wuchen's eyes were wide with curiousity.
Shi Wuchen was not all too surprised at Yun Yang's plan of making him his top henchman. After all, his cultivation base was right there, sitting idle — he should be contributing to the sect since he was already a member of it. At the same time, it could not possibly come as a surprise to him that Yun Yang had volunteered to heal him — he would only be able to unleash his full strength if his wounds took a turn for the better. That must be what he had intended, and it was a perfectly reasonable gesture.
In actual fact, Shi Wuchen was utterly shocked by the fact that Yun Yang had sworn to heal him in three days!
