Elves?

Even without Vesa, he could still do some preliminary research.

Swosh! 

Alex thrust the knife forward, expecting it to pierce the tree bark. But what happened was unexpected. 

The moment the knife pierced the bark, it was like the bark turned into a sponge, and the knife was just a normal wooden stick—it was pushed back out.

It was like Alex was punching rubber. 

He blinked a few times to process what had happened, then turned his gaze to the knife, which had lost its blade.

There was no sound of metal breaking; it was like the blade had been eaten by the tree.

Alex focused his gaze on the tree, then looked at his hand. He hesitated for a moment before becoming determined. 

He started moving his shoulder, trying to punch the tree, but only halfway through, his fist was stopped. 

MingYue's cold hand gripped it.

"What do you think you're doing? Are you stupid?" She asked coldly.
