Su He suddenly understood, so this is why there are no immortals in later generations?
So... when he went back to Ji Feixue's era, the Free Bodhisattva's avatar was causing trouble in the Mystery Yellow Cave Sky; even if Su He didn't stop him, it would be impossible to open the Fairy Sect?
Therefore, neither the Phoenix Ancestor nor Thai Zu took him seriously and didn't intervene...
No, actually, they wanted to see if the Free Bodhisattva could open the Fairy Sect. If he truly could, it would offer the beings of Mystery Yellow a straightforward path to the heavens?
At any rate, even if the Fairy Sect is opened, a mere two-realms Immortal Sovereign would crush it effortlessly.
Condensing the Fairy Sect is not something that can be done overnight. As many Immortal Sovereigns contribute, Su He quietly retreats. He returns to the spacetime passage again to try to reconnect it.
