"Hey! Hey hey…" Zhao Yu smacked the metal door while shouting, "Is there anyone in there? Anyone? Sun Yihan, are you in there?" As it was damp, the cold metal door had many water droplets hanging off of it. Zhao Yu's hands were wet after he smacked the door.
"Bark! Bark bark…" Daheng felt that he had contributed successfully. It ran around Zhao Yu in circles while barking.
"Stop, stop barking! I can't hear, shh…" Zhao Yu shouted and Daheng then lied down.
Dong dong dong… Zhao Yu smacked the door again, but he could not hear anything going on behind the door.
Sh*t! Zhao Yu was panicking. "If Sun Yihan is locked inside, in such a dangerous environment, I wonder if she is even alive." In his desperation, he pulled the door lock on the metal door. The big lock hung outside the door was could not be opened!
