Are the Sister and Brother Demons?

What is this?

That Swordsman felt confused immediately.

Mental strength?

He had never seen mental strength in such a shape!

A diffused mental state would become more powerful after compression. Therefore, almost all the Swordsmen worked hard to collect their diffused thoughts!

However…

This mental strength…

Crash!

It was only one collision and he could already feel how terrifying this disc-shaped mental state was!

Although this mental state was round and big and looked like a pancake from the front, it was extremely thin when viewed from the side!

It had already been compressed to the limit!!!

Shush!

Cold lights flashed.

In the empty world of mental strength.

He could feel his metal strength, already condensed to an extremely solid state, being severed by that compact disc easily…

Pfft!

His thoughts diffused!

The Swordsman vomited blood on the spot.
