Although Li Du had his back towards the young man, Brother Wolf, who was beside him, did not. The young man swung his fist, and Brother Wolf immediately rushed over and grabbed his arm. He twisted both of the young man's arms towards his back without any effort. Brother Wolf was grabbing the young man as if he were grabbing a little chick. He pulled him aside and then pushed him towards Princeps as he let him go.
Obviously, he had also seen through Princeps' trick. That was why he was not as fierce as when he had dealt with Princeps before. Otherwise, the young man who initiated the attack on Li Du would have two broken arms.
Seeing that Brother Wolf had not hurt the young man, Princeps seemed perplexed by it. He seemed like he was at ease, but at the same time like he was sorry.
