Understanding the Way of Law, Playing the Role of Law?

The countless, menacing Hurricanes suddenly changed their course of attack. Instead of surging toward Sterl, they instead clustered closely around their master for protection.

That's right, the peak legend who had shown such arrogance upon his arrival...

He was backing down now!

Moreover, he was directly riding the Hurricane, fleeing at top speed, intent only on getting as far away as possible.

The other two peak legends were also ghostly pale; they had just felt an incredibly complete Law Power emanating from the blade!

And...

This Law Power was purely the Flowing Water Law, devoid of any rules regarding blades or weapons.

So why would that strange figure choose to attack in such a manner?

The only possibility was...

A platinum-grade skill!
