The main storyline "Dark Revival" in version 2.0 differs from the "Scarlet Ceremony" in version 1.0 in that this major quest doesn't require the so-called NPC commanders, allowing players to explore and adventure in the Spirit World on their own.
This effectively opens up a large dungeon with incredibly high freedom, teeming with an endless supply of monsters to kill and a map so vast that it could keep players busy for a very long time at this stage.
Explained using the results of the official meeting discussions, the realm of the Spirit World is so vast that even if all the major powers sent high Combat Power to lead, they could not achieve more effective results, and since the Empire and Church do not have enough manpower, they decided to let the "Undead Foreigners" pour into the Spirit World en masse to act independently. This would also enable faster detection of pollution creatures' traces.
