With so many cultivators consuming spiritual energy, the spiritual energy in the Nine Provinces would be completely depleted in no more than a few thousand years.
Therefore, the ancient cultivators sought different ways to find a solution.
Those Immortals, confident in their own strength, tested the Beiming Youdu array which merely closed the connection with the Immortal Realm but was still practically usable.
They directly transmitted themselves to the Immortal Realm.
At the time of their departure, the Immortals had promised to investigate the reason for the disappearance of the Immortals and then reopen the passage between the Two Realms to save the Immortal Cultivation World in the Nine Provinces.
The Nine Provinces cultivators, with hope, waited for news from those Ascended Immortals.
Yet after waiting for a full thousand years, there was still no news.
Those Ascended Immortals, like the Immortals cut off after the closure of the passage, never sent back any news.
