Chameleon

Greg shuttles through different corridors adeptly. When he comes across anyone he would greet them, if it is a superior he would offer his salutations.

Exiting the main building, Greg disappeared among the crowd. When he reappeared, he was already inside the oldest building in the base. This place is far from the main building and relatively secluded.

Arriving at his destination, Greg noted the absence of the guard on duty.

"That guy is probably napping somewhere. Even high-class organization had their share of bad employees I guess." Greg shrugged, if nothing, no guards means that he could execute his work safely.

But he didn't know that he was gravely mistaken because, at the stairs on the second floor, a person is watching him.

After turning the knob of the cubicle to show occupied, Greg reaches for the tank and checks his supply: a gas mask and a case with a built-in cooling system. Not much could be said about the gas mask, the case however is filled with vials.

A quick count reveals their number to be a total of 12. Some are red, some are blue, some thick and some are watery.

"We struck it rich this time!" Greg licked his lips imagining the ways he'll use the money he would get from turning over these vials.

Footsteps suddenly sounded outside as Greg sprung to his feet, back on the door of the cubicle with a knife appearing in his hands. The series of actions happens so fast yet no sound was generated. What's more, as he held his breath his presence decreased to the point where ordinary people may struggle to tell him apart from his environment.

This is the technique that Greg was most proud of and the basis of his moniker: Chameleon. Chameleon was a mercenary specializing in assassination and infiltration. Therefore, he was the one sent by his companions to steal research materials for their clients.

The footsteps quickly reached two meters to his cubicle but then they stopped. Confused, Chameleon Greg positioned his eyes so he could see through the gap in the wooden door.

1, 2, 3... 7, 8, 9

Whoosh~

Snap~

Chunks of wood and splinters fly through the air as a hand emerges from the cubicle next to him grabbing his throat. Following this, a strong figure emerge from the other side of the wall.
