Discovery

Rui simply stared at him with sharp eyes.

He did understand. To a certain extent, he felt the same way. 

He was not going to hold back.

He couldn't. Not if he wanted to break through to a higher Realm of power.

The Martial Heart was a power that could only be accessed if he was pushed beyond the limit of what his conventional power could accomplish. This meant that holding back was antithetical to the very nature of the activation of the Martial Heart.

That was why not only was Rui not going to hold back physically, but he had already psychologically conditioned himself to not hold back mentally even in the slightest.

That meant no mercy.

No compassion.

No empathy.

If his opponent's death was a consequence of that, then he wouldn't feel any guilt over it either.
