Bab 6: Beasthuman Trump Card!

"It's now or never!" Rex's dark brown aura surrounds his entire body. 

Crack, crack! The ground beneath his feet collapses, revealing several fractures.

He draws his sword and swings it towards Regulus. 

<Aura Blade Slash> A 10-meter-long dark brown cut crashed straight into Regulus.

"I can also do the same thing!" Regulus' blood-red aura surrounds his entire body, boosting his physical attributes. 

Crack, Crack! The ground beneath his feet also collapses, exposing several fractures.

( I don't have time to use <Inferno breath>) 

<Dual Blaze Claw> Regulus wraps his claws with fire energy before slashing towards the blade slash.

Two crimson-red claws entirely made of fire clash with dark brown blade slash. 

Boom! Clash! Their clash creates shockwaves. Smoke filled the battlefield.

"I start hating the smoke more now than Jack.'' Rex grumbles.

<Inferno Breath> Regulus launch his breath attack towards Rex.
