"Pitter-patter, pitter-patter, pitter-patter..."

In the staircase leading to the Third Underground Level, messy and hurried footsteps echoed.

Security personnel were not regular soldiers after all, and their vigilance was lacking. Even though they were aware an enemy was present, they exposed their own footsteps.

Noland Lee followed in the team, frowning slightly and watching the spot where the mechanical spider had an accident.

The two bright red figures were alarmed by the footsteps.

They picked up several alchemy parts, then lightly jumped down through the hole into the Fourth Underground Level.

Throughout the entire process, they didn't make any strange noises. It was apparent that they had been in this dark underground area for quite a while and had rich experience.

They might be illegal alchemists from Black City... Noland Lee speculated in his heart.
