Exploring the tunnel

Erik resumed his journey with the metal bucket in hand, its flaming glow casting swirling shadows on the tunnel walls.

The flickering flames illuminated the road ahead of him and dispelled the approaching darkness that threatened to devour the tunnel, but they couldn't show everything. The area was mostly dark, and the young man had to be aware of his surroundings because thaids might attack him anytime.

Erik said to the biological supercomputer.

[UNDERSTOOD,] the System replied with its usual robotic voice.

Erik's senses intensified as he went further in, alert to the slightest changes in his surroundings. The tunnel seemed to stretch into the depths indefinitely, its walls a tapestry of texture, and bugs scurried on its surface.
