307. Shadows surge

Under Noland Lee's command, the Rock Spirit raised its stone fists and slammed them on the ground.

In the underground space, a layer of dark gray rock emerged on the ground, sealing the tunnel entrance dug by the Ground Drilling Mechanism.

The chilling draft that filled the narrow space dissipated at once, reducing the noise emanating from the shadow pupa cocoon to a mere whisper.

Noland Lee let out a sigh of relief, but he did not let his guard down.

He directed the Rock Spirit to construct more rock layers, tightly sealing every direction - front, back, left, right, up, and down.

An airtight enclosure quickly surrounded both Noland Lee and the Rock Spirit.

Noland Lee listened intently.

The noise was almost inaudible now, and it wasn't moving towards him anymore.

He nodded to himself, recognizing that his quick thinking had taken effect.

Noland gave the command to "stay on alert" to the Rock Spirit and brought up the Systems Interface in his mind.
