In the stairway from the second underground level to the third underground level.
The Imperial Army marches forward, heading for the battlefield.
If one claims not to feel nervous about the upcoming battle, it is pure untruth.
The surrounding silence and the muffled breathing sounds emitted by the breathing masks all reveal the immense pressure on the soldiers' minds.
As they approach the depths of the third underground level, the coal lamp's light is barely visible.
An invisible magic force envelops the Imperial Army, pushing everything related to "light" and "hope" to the farthest corners.
The light released by the coal lamps cannot escape the range of the lampshade, only lingering on the inner side of the glass cover and not even illuminating the soldiers' faces.
Everyone has to take potions with night vision effects, and act under rough sight conditions.
At the same time, faint painful whispers linger in every soldier's ear.
