Strong

The fist carrying enormous force quickly moved towards Aru's face. 

Kaan was expecting Aru's head to burst like a watermelon. 

But,

"Thump!" The fist collided with an open palm.

Instantly, its energy diffused and released as a mini shock wave.

Kaan was terrified.

When he looked at his fist, he saw Aru giving him a devilish smile while clamping onto it with his palm.

Kaan couldn't believe it.

The kid he thought of as nothing more than a nuisance was firmly grasping onto his fist, stopping it firmly in its position. He found it extremely difficult even to move it.

"What are you? A demon?" 

Kaan couldn't believe a human could be as strong as Aru in their teens. This made him question whether Aru was a demon.

After all, he was a rank 4 warrior. So, how else could a teenager block his attack? 

"Now you are accusing me of being a demon. Is that the best you can do?"
