The man in black ascended to the third floor, glanced at the living room, and then walked to the first room, twisting the doorknob.
The door wouldn't open; it was locked.
The man in black stepped back two paces and launched a kick at the door.
After two kicks, he broke open the door and walked in.
He stayed inside for less than ten seconds before he knew the target wasn't in that room.
The man in black quickened his pace, heading for the second room, which was also locked.
On the surface, kicking doors took little time, and the other party's actions seemed superfluous.
But the man in black knew it was an extremely effective trick.
If it took three seconds to kick down a door, then twenty doors would require a minute. A minute, for an assassin, was a very long time. Moreover, kicking doors down also used up a lot of his strength.
With two flying kicks, he broke open the door.
