Poison

Watching the Ape scream and roll on the ground, Alex couldn't help but be surprised. 

Sure, a cut to the arm was painful, but… not that painful, right?

As he watched, suddenly he noticed something. White fizz appeared around the corner of the Ape's lips.

'What?' Alex was a little surprised. 

"It's been poisoned," the oldest man of the group said with a hit of fear in his eyes.

"What?" the Ape's master looked at it and then towards Alex. A hammer appeared on his arm and he rushed forward.

"I will kill you myself," he shouted.

The other two looked at him in confusion and then terror. "Idiot! Come back, you'll die," the older one shouted, but the man didn't hear him at all.

"Good," Alex said and dashed forward. 

Just as he was about to reach Alex, the man's eyes suddenly lost all hint of anger, and instead a calm but serious look took its place.

Then, the man suddenly changed his direction.
