Chapter 614 - Chapter 80 The Trouble Named Sigein_1

Entering the building at the heart of Ava's description, they saw a round hall that stretched hundreds to thousands of square meters. Four large doors were symmetrically distributed within the hall; aside from the door they just entered through, three other metal doors were tightly closed, their destinations unknown.

These doors looked similar to the elevators they had seen in the Tower of Colossus, each door accompanied by directional arrows pointing up and down. It seemed like they were a more advanced version of the Goblin elevators they had encountered before.
