You are a demon slayer

The egg landed on the men in black overalls and opened up like a smokescreen. The next second, 

BOOM!

The deafening explosion threw the men off their feet. 

A strong acrid smell waft through the air. Lucien watch with sharp eyes as the men grovel in the ground, holding their throats and gag. 

"Wow!" Langris marveled. "These balls, they aren't poisonous aren't they?" 

Langris approached the three men who held the box on their hands. 

"No, sir. Misha gave these balls to us. Sir Dan suggested that if we get ambushed by players we must use these to render them unconscious." 

"Hahaha!!" Langris laughter echoed in the street. 

"Misha that bastard, he should have given us these new inventions of his right from the start. This is the first time one of his creations ever has some use." Langris's face is coated with dirt and plastered with mud but his smile almost shun the others because of its brilliance.
