The underground base wasn't as technologically advanced as Su Huan imagined; it resembled the old-style arsenals he saw before in the Acid Rain Zone. The walls on both sides were cast from reinforced, blast-proof concrete covered with dark gray impact-resistant paint, emitting a mixed scent of cold metal, faint engine oil, and disinfectant, giving him a heavy sense of security.
After dual authorization, the two entered the core region of the base.
The interior scene unfolded before Su Huan, with a broad main passage running north to south through the base, eight meters wide and six meters high, enough for a tank to pass through.
The LED light strips on the top were arranged linearly, emitting soft yet ample white light, illuminating every corner of the passage.
Different functional areas were distributed on both sides of the main passage, with each area's entrance having independent isolation doors and identity verification devices, yet it was deserted.
