As the glass piece was thrown at a fast rate, the bodyguard was caught off-guard, unable to dodge in time. 

They could only raise their sturdy arm to block, but the glass piece easily pierced through their tough skin, leaving behind a noticeable cut. Soon, blood began to seep out from there.

"Heh, what a weak punch—" Just when the bodyguard wanted to taunt the weak punch, he suddenly felt an unknown force churning in his stomach.
