Chapter 152: Pest Control.

Yang Dao heard Tony confirming the situation check. He dusted his clothes took out this suppressed handgun and walked down the staircase leading to the roof after he gave an OK signal to Tony. This guy was very skilled, he arranged the three cameras and left a blind zone for himself and Yang Dao. 

The dao child moved quickly but carefully. He crouched as he entered the staircase. He also made sure to avoid creating any sound as well by keeping his body away from the walls and the railings, lest he touched them accidentally. The target was residing a floor below. 

Soon Yang Dao heard some voices, "Matthew, for how long do we have to stay here?"

"I don't know. Well, these higher-ups are crooked. They did not want to expose themselves so hired us. Humph, I hate cowards like this."

"Yet you love their money."
