At this moment, the two Grand Priests used all their strength and took a full five minutes to slowly lift the forty-ton iron gate to its highest position.
This iron gate, three meters high and five meters wide, was finally opened.
Lin Feng then entered.
However, Xu Wanshuang, behind him, could not enter together, because only the Oasis Key holder could enter with the identity of a captain.
As for the personnel inside, they were secretly selected and sent in blindfolded and could only report and communicate with the Oasis Key holder.
The daily food was also delivered through secret routes.
It can be said that to ensure the safety of the control room, its secrecy has been taken to the extreme, equivalent to a submarine within the battleship, isolated from communication with the outside.
Therefore, those inside are the most loyal believers, and once their service term is up, they can enjoy the best treatment.
