The gunshot is the signal.
What will be the first reaction of the enemy upstairs when their accomplice downstairs suddenly falls to the ground after being shot?
Panic?
Seek cover? No, for these fanatics who lack rigorous training, it's more likely they'll instinctively rush over to check their comrade's condition!
This is a basic human reaction, especially inside a building they believe to be safe.
Song Heping bet that he would move and expose himself.
He was right.
Everything was as he had anticipated!
The echo of the gunshot hadn't even faded when a figure appeared behind the window.
An armed man also wrapped in a headscarf, with obvious shock and slight panic on his face, peeked cautiously towards the staircase. Immediately after, as if seeing his comrade's fallen state, he jerked violently and instinctively rushed toward the staircase!
He completely forgot to find cover, exposing his entire upper body to the window in an attempt to see what happened downstairs.
"Fool."
