Kim Hajun uses his dragon fang slashes horizontally and vertically continuously to slash the swarm of lesser wyverns.
At first, when his dragon fang slashes hit those lesser wyverns, it didn't give any scratches, but now his dragon fang slashes pierced the hard scales of those lesser wyverns and cut through their meats.
Those lesser wyverns screamed in pain and let out a very loud sound which caused the other lesser wyverns to start coming towards Kim Hajun.
When the other lesser wyverns in great numbers had arrived before Kim Hajun, they saw that their comrades were mostly exhausted by Kim Hajun and it infuriated them to the point they emitted such an intense murderous killing aura.
Those lesser wyverns charged straight toward Kim Hajun clones and bite them all to death.
When Kim Hajun's clones die, they turn into blue particles of light, and at that very moment, Kim Hajun can feel the pain they feel even though he took no damage at all.
