The ones who got pushed behind kept trying, but the same thing kept happening. They recalled that the rumors said that only cultivators would be able to ascend the immortal mountain. One by one, they retreated with disappointed expressions. There weren't many who got rejected, however. A significant proportion of people there had spirit roots.
The so-called ladder of ascension was what Fatty used to select disciples back in the small realm. It was different from the Three Azure Realms. The Sacred Arrival Realm that Fatty was in only contained immortals who were cultivating, therefore there was only a small minority who did not have spirit roots. However, immortal sects there had certain standards. Naturally, they were strict about the disciples they accepted. Not only did they have to have spirit roots, they had to be of a certain caliber and character etc.
