After becoming the controller of the Divine Tree, Luo Xi already knew that the controllers didn't care about low-tier formula pathways, such as the 'Garden Skill Practitioner' formula that Lena once showed them, or the low-tier Sublimation pathways that were common knowledge.
However, from Third-tier onwards, that was when Transcendents began their qualitative change. For a Divine Tree, the number of people it could turn into Third-tier Transcendents and above was limited.
A Divine Tree of Vita Village's caliber could support at most the village chief and three other people in becoming Third-tier Transcendents.
Belgri could support one early Tier Four individual, other than the Lord, as well as ten Tier Three individuals.
The Winter Divine Tree could support two Tier Four individuals, other than the City Owner, and many more Tier Three, but not excessively so.
This was the upper limit set by the size of the Divine Tree.
