This underground storage warehouse, located two hundred meters underground, contained many valuable and precious items and was crucial for Area 51. Therefore, the warehouse was filled with high-precision anti-theft traps and equipment. A large hole had been drilled into the ceiling, and the rocky material of the wall had fallen onto the warehouse floor. Due to the sudden change in pressure, the alarm devices installed on the floor were triggered, and a piercing alarm sounded throughout Area 51.
Yan Fei ignored the alarm and continued to navigate the drone downwards, squeezing the cockpit into the storage warehouse, before coming to a stop, just hanging from the warehouse ceiling.
