Rat-a-tat-tat—!
The submachine gun's sweeping fire continued.
It was practically spitting blue flames!
Xiao Bei remained remarkably calm as he hid behind the wall.
It lasted for about three minutes.
The gunfire stopped.
At that moment, Iron Tower, standing behind the door at the stairwell, gave the people beside him a signal.
"Go down. Kill anyone you see!"
"Yes, boss!"
With that, one of the men kicked the door open.
Two men behind him immediately fired rapidly toward the stairwell.
They were laying down covering fire.
Very soon, the man in front looked into the dust-filled basement.
He did not see Xiao Bei.
Then he slowly made a hand signal.
Gun raised, he slowly walked down the stairs.
Three armed men followed behind him.
Iron Tower stood at the rear.
Soon, the four of them reached the middle of the staircase.
They looked at the corpses strewn across the floor.
One of the men immediately fired additional shots into the bodies.
They could not leave these people alive.
For safety's sake, they had to make sure everyone was dead.
Otherwise, if they were captured and talked, it would cause major trouble.
After all, this was the Xia Kingdom.
The man in front moved very slowly.
Soon, he reached the basement door.
He turned and signaled the three men behind him to storm in from both sides.
Just as he was about to step forward.
Because he had just turned his head, when he turned back and took a step in—
He happened to step on broken glass on the floor.
Crack—!
The sound was faint, but everyone held their breath.
They were all retired mercenaries.
They naturally knew that on an uncertain battlefield, that sound—
Could cost them their lives.
Sure enough, Xiao Bei, hiding behind the wall, heard it
