Canglang Palace was already considered the major contender by various factions, and many affiliations were absolutely not willing to see the Great Elder of Canglang Palace succeed in breaking through and promoting Canglang Palace to become a top-level power.
Because if that happened, they would be following in the footsteps of Taixu Sect, causing them to lose many of their interests once again. Thus, they didn't want to see such a situation arise.
Originally, Canglang Palace had five cultivators at the Eighth Level of the Spiritual Realm, and no top-ranked faction could confidently act alone. If all factions joined forces, then they would have to take into account the vague kindness the Taixu Venerable had towards the Great Elder, they wouldn't dare act rashly.
