Chương 2135: Ventilation

At the door, the two guards suddenly realized that a black fog had risen from somewhere and were instantly stunned.

"What's going on?!"

The guards' initial reaction was to the black smoke emanating from the fire, and they all turned their heads to look at the gate.

"Is it on fire?"

Looking down, they saw a large amount of black smoke billowing out from the crack in the door!

"Bang!!"

Before the two could open the door to inspect, something from inside kicked the room door open first!

Instantly, thick black fog surged out from the doorway!

The black fog almost instantly obscured their vision.

The two guards quickly retreated backward.

"What?"

Whoosh! Whoosh!!!

The two of them were blocked by the black fog. They could only hear several sounds of wind coming from the black fog in front of them as if something was flying past them quickly!

"Bang!!!"
