Inside the Demon Refining Island Base, Gu Fan, Lin Yue, Leng Feng, and Gu Xiaojin walked together, pretending to be part of the base's personnel as they patrolled and searched.
The base was massive, housing at least a hundred thousand people with constant movement between floors. Once Gu Fan and the others blended in, finding them would be akin to searching for a needle in a haystack.
Gu Fan's current goal was to return to the room they had initially entered, and use the ventilation system there to leave the Demon Refining Island Base—essentially, to exit the same way they had come in.
This problem also left the enemy commander at a loss. He was trying to figure out how these people had managed to infiltrate the Demon Refining Island Base, especially since no entry or exit points had been activated in the past three days, and surveillance hadn't captured any signs of an approach, not even from a fly.
