Chapter176-The Vampire Bat King's Killing Blow

John clenched his teeth and plunged his knife into the underside of the Vampire Bat King's chin, then swung it violently to the side!

Using the momentum of his body, he swung towards the boss's neck, slicing open a large gash.

The stench of the blood that sprayed over him was nearly enough to make John vomit, but he forcefully suppressed the urge and controlled his stance.

When John finally landed on the ground, the Vampire Bat King let out a sharp, explosive cry!

But at that moment, the Vampire Bat King could no longer emit its sonic attacks; instead, it flew around the cave like a headless fly.

It could no longer use its vocal cords to produce ultrasonic waves, nor could it locate its surroundings with any certainty.

As the Vampire Bat King continued to crash into nearby stone pillars, even breaking some of them, Isabella felt a slight relief.

She nodded at John.
