"Let us take care of this! Vincent, step back. I am afraid my attacks could hit you. " Biro urged. He wanted to eliminate the threat immediately, but Vincent was too close. Biro didn't want to injure Vincent by accident.

"I said Submit!" Vincent swung his hand and slapped the tiger with all his might. The tiger's jaw became dislocated, yet it kept glaring and growling weirdly.

"Damn it!" Biro had no choice. He went beside Vincent, grabbed him from his gauntlets, and tossed him a few meters in the air.

Biro channeled a spell in his blade and combined it with Energy Flow. "Splinter Slash!" He shouted while swinging his blade engulfed in power at the tiger.

When the blade swung, an arch of pressurized mana, with sharp paper-thin earth as the arch's core, made a sharp turn upwards and chopped the tiger's head off. 

*Thud* The tiger's head fell, yet the body bleeding a fountain of yellow blood, remained standing.
