Elmer's body ached with exhaustion as he made his way towards Devin.
"Any mana left?" he asked, panting heavily.
Devin shook his head, sweat glistening on his brow. "No...we can only use life essence to defend ourselves," he replied, squatting on the ground and using his hand for support.
The massive bull kicked the ground and charged towards them, its eyes blazing with anger and power.
Elmer gripped his sword tightly, its red glow illuminating their surroundings. Red threads of mana spread out around Devin, ready to be used.
As they had exhausted all of their mana essence, their only option now was to use their own lifespan to fight.
Without hesitation, Elmer charged forward and swung his sword. Devin's red mana threads easily slowed down the bull's movements.
With a powerful strike, Elmer managed to cut off one of the bull's horns. But before he could celebrate, the other horn glowed and released a blinding light beam.
