For them, even if they stayed in the Star Spirit World, they could still enter the Sky High World every few days through the exit of the high tower, so why take the risk?
Of course, the difference between exiting through the server and directly ascending to Sky High is significant. The terrain near the exit of the high tower is narrow, limiting the range of exploration. Additionally, after the pioneering efforts of the previous generation's Fool, most valuable resources nearby have been depleted. Not to mention, in the future, billions of players will be crowding around this singular exit, which will undoubtedly result in a situation where demand far outstrips supply.
After ascending to Sky High, not only will their vision be completely liberated, but they will also be able to teleport between cities, with opportunities and rewards that are incomparable to remaining in the Star Spirit World.
