Yu Tian walked along the passage above and arrived behind an iron door. After taking a look inside, he quietly stepped aside and clenched the dagger in his hand.
He heard footsteps and two impatient voices behind the door.
“What bad luck. Didn’t you just fix it?”
“Sigh, I’m too lazy to say. Hurry up and open the door. Let’s take a look.”
“Okay.”
With a creak, the rusty iron door was slowly pulled open.
Two men dressed in light yellow prison uniforms and two yellow coats walked through the iron door with toolboxes.
In an instant, a black shadow flashed past their eyes!
The two men were stunned. Their bodies froze and their eyes widened in shock.
They lowered their heads in disbelief. Drops of blood dripped down from their chins and eventually turned into puddles of blood that flowed down their clothes.
In the next moment, the two men stretched out their hands in extreme pain and covered their necks almost at the same time.
