Besiege

The invisible blade cut open the mercenary's throat, and through that momentary pause, everyone saw the transparent figure. However, when they wanted to focus their eyes and search for the person's trace, he had disappeared again.

"Fu*k, it's optical invisibility!" The mercenary with the automatic rifle screamed in horror, and hurriedly fired a clip of bullets toward where the man was. However, he did not hit the transparent figure, but instead almost shot another mercenary that was leaning against the door.

Fortunately, the guy reacted quickly, and he was able to escape the clip of bullets. Otherwise, it would be awkward to not die in the enemy's hands, but by friendly fire.

"Idiot! Don't just shoot, you almost hit me!"

"AHHHHH!!!"

Amidst the chaos, another mercenary had his throat slit open. He covered his neck in pain and collapsed in a pool of blood.
