After the 40th floor was cleared, of course the option to enter the 41st floor was open. But Alex hurriedly told Evan and his friends not to try it without having a dozen mid stage Sky realm Magus fighters, lest they be completely obliterated.
Checking the condition of everyone including Evan's men, Alex then gestured to them to return to the main hall. As they entered the hall, they saw that the safe room which previously only had 4 panels [Main panel, store panel, skill library panel, and recovery room panel] on it now has a new fifth panel.
Sergei who saw the additional panel was surprised and could not help but exclaim, "That is new! What is that?"
[Core Room]
[Do you want to enter the room?]
This is the room that Alex spoke of and briefly explained at the World Conference 7 months ago, a room that will be the ultimate solution for humanity to survive during the tribulation.
[Yes]
