"The so-called open-but-closed world is a restricted area within the open world. Although the whole world is intact, players' actions are confined to a certain fixed area. The blockage may be due to natural disasters, human errors, or compulsory mission rules.
However, you won't find the 'air wall' setting of Boxed World here.
That means if a player is powerful enough to break through the map's blockade, they can ignore the current mission requirements and head directly to the vast open world for adventure. Generally, though, no player chooses to do this. Not only does abandoning the current mission lead to a deduction in points, heading to unknown regions could also lead to encounters with greater dangers, and most likely won't trigger hidden side quests, making it mostly not worth the risk.
