He couldn't help but be afraid. First, Hell Cat King had been killed by Chu Yunfan with two slaps. Then, the Ape King, who had entered the Core Form Stage, was killed by his own magic weapon in two whacks.
The ape king's magic tool was a middle-grade spirit tool. All of them had spirit energy, but there was not the slightest bit of resistance. What did this mean? It meant that the moment Chu Yunfan grabbed the staff, he suppressed the weapon with absolute strength. Then, he unleashed such an astonishing attack.
Core Formers were kingdom guardians. In the demon league, where there were many powerful warriors, they were at the top of the pyramid. How could he not be afraid when his comrades were casually knocked struck to death?
