The entrance to the basement was an iron door. Ludmila gestured, and two team members took cover on the side, their guns aimed at the door, while she slowly pulled open the door bolt with her right hand clad in a tactical glove.
Squeak... A harsh metallic scraping sound made everyone's ears ache as the rusty iron door slowly swung open. A chill wind rushed from the doorway, mixed with a thick scent of blood.
Upon seeing the scene behind the door, Ludmila and the team behind her couldn't help but frown.
Before them lay a deep and dark arched passage, wide enough for three people to walk abreast, over two meters high, and sloping at a gentle grade heading underground.
Along the passageway, at intervals, dim electric lights twinkled, the light revealing that the passage stretched farther than the eye could see.
Based on the slope, the passage was probably tens of meters long just by itself.
