Only the middle-level factions represented by the three tower masters of the Stargate Tower found it difficult to accept, because their goal was not only the willow tree cores but also the spiritual spring.
Other than the fact that the three tower masters did not have someone at a higher level to support them, their true combat strength was not inferior to the three inner court heads of the Myriad Phenomena Sect. If they relied on their own abilities, even if they gave the Myriad Phenomena Sect face, they would still be able to gain something if they obtained less than the other party.
On the other hand, if they split it according to their strength, the portion of the spiritual spring that they originally had a chance of obtaining would be completely snatched away. They would not even be able to get a single drop of it.
