บท 1248: Elite Sitting Position

The "Sound Seeker Technique" had wall-detection capabilities that far exceeded Noland Lee's expectations.

The stone wall was about two meters thick, composed of two layers of heavy square stone bricks.

There was almost no gap between the stone bricks, not even a blade could penetrate.

Under these circumstances, the sound waves of the "Sound Seeker Technique" still penetrated the stone wall, reaching the outside of the stone wall and entering the corridor adjacent to the Treasure Room.

As for the lighting in the corridor, Noland Lee did not know as sound waves could not capture information related to light.

But Noland Lee was certain that the corridor was littered with bones, piled up more than half a meter high, which would likely be difficult for ordinary people to walk through such rough terrain.

As the sound waves transmitted further, more and more blurred scenes appeared in Noland Lee's mind, and he faintly detected a series of hurried and somewhat panicked footsteps.
