Xu Feng's accuracy in the weapon that was not specialized for his class astounded Zhao Kai. 

The reason was that not only did Xu Feng accurately shoot at the critical flesh points, but he continuously did it repeatedly without pause.

To top it off, Zhao Kai noticed the recoil was lessened tremendously, and Xu Feng barely moved much in between each interval of shots. 

'W-Why did he choose a Cleric class then?' Zhao Kai was stunned on the spot, completely speechless at Xu Feng's capability and somewhat odd decision. 

Sometime later, Xu Feng effectively killed the Ironwood Treant after much effort. 

"Did you observe everything?" Xu Feng stood up, turned to him, and asked. 

"Uhh–yes," Zhao Kai responded, albeit lacking some confidence. If he were suddenly tasked to repeat his actions, then it would be over for him.
