Chapter 53: Nightmare Beast's Fate

A sound like thunder echoed through the treacherous mountain as Romero's fist crashed into the beast's jaw, sending it flying backwards.

The light on Romero's arm had disappeared at that moment.

*drip*

Blood trickled down Romero's right hand, his muscles torn from the pressure that was exerted on it.

At that moment, Romero and the others all dropped to the floor. They had completely used up all the mana in their bodies causing them to collapse. 

In the martial world, this was a common occurrence when someone ran out of mana. When a martial artist starts practicing, a small portion of the mana they absorb is used to nourish their body, strengthening it so that it can store larger amounts of mana.
