There must be some kind of restriction among them, restricting the eleven days.
Upon closer reflection, from setting sights on the Spirit Realm to gradually being able to descend, the eleven days seem like a progressive process. First came the immortal winds of the Southern Sea, various strange storms, and the eruption of Immortal Dao material, crafting a so-called golden era in the Spirit Realm. After batches of immortals appeared, the eleven days could finally briefly manifest in the Mist Sea…
Now, as these "pigs" return to the Spirit Realm, it won't be long before beings from the Exotic Realm can roam freely across the Spirit Realm lands unrestricted.
That would truly mark the beginning of the catastrophe.
