While carrying the laptop, she hacked into the system and unlocked the back security door, and they got inside. She hacked into the CCTV cameras, she wanted to know how many floors down they had to go, and luckily it had only three floors, but the surface area was huge with many random rooms with mage corridors.
"All right, Qin Zhilin, we have three floors down, but I think she is on the second floor as the third floor underground is always a bit darker with heavy shadows which I didn't see." She changed the security fingerprint and placed hers for easier access across the security doors; they walked through the several security doors; they weren't any less, and it seemed like there were many people downstairs.
