Chapter 622: Discovered

Time quickly went by since Xu Feng and Aera had escaped the isolated area room. 

Numerous guards patrolled each corridor, prompting them to stay hidden and wait patiently until the coast was clear.

Thus, what would usually take around 5 minutes of walk, turned into half an hour before they finally reached the emergency exit door.

As the emergency exit door required a scan, Aera attempted to use her card, only to end up being denied access.

"Tsk, they are quick." Aera clicked her tongue in annoyance. She proceeded to test with some of her backup access cards. However, all of them ended up being denied and the hologram prompted that there were only two attempts left.

Once those two attempts were used up, an alert would be sent to nearby guards to check the situation. 

"Here, try my permit slip card." Xu Feng said. 

"A permit slip card?" Confused, Aera glanced at Xu Feng as if he were a fool.
