The ability that caught Bai Yi’s attention was the qualitative change that occurred in her abilities during the [Forest Elf] stage, which involved integration with plant abilities.
This ability was originally considered part of Plant Affinity, allowing her to merge with the plants she had a contract with at any time, and to directly utilize the abilities of both herself and the contracted plants.
With proper coordination, during combat, this could even demonstrate power equivalent to more than 1+1. Under the modifications Bai Yi made for You, Bai Yi in her merged state could even contend with Rank 6.
After this promotion, this ability was also enhanced.
The target of Fusion is no longer limited to the contracted You, but has expanded to all living beings, and has derived a new ability named [Tree Sea Exploration].
It allows her to teleport to some extent in areas with abundant vegetation.
However, Bai Yi has already modified herself to acquire the Space Ability typical of the Cat Witch, rendering it largely redundant now.
Her original Transcendent Ability, shared with her contracted plants, has also expanded in scope during this promotion, allowing mutual borrowing of all Transcendent Abilities.
However, the level of ability borrowed is one rank lower than the original, for example, she could use You’s Rank 6 Annihilation Light, but can only exert the power of Rank 5.
The output cap is significantly reduced.
The part concerning the soul mentioned by Bai Yi is an additional ability she obtained after this promotion.
The effect of this ability is very simple, with just one feature.
It allows her to resurrect through plants upon her death.
Of course, not just any plant will do; she must undergo a process similar to forming a Contract, and the resurrection is not perfect.
The contracted plant will suffer severe damage, almost as if transferring its fatal injuries to the contracted plant.
If the contracted plant is weak, it might even die as a result.
Moreover, her physical condition after resurrection is extremely poor, with Life Value and Magic Power Value dropping to less than 1%.
Rather than a resurrection, this is more like a plant sacrificing itself in her place.
Typically, such plants are contracted from forests planted during her Forest Elf stage, relying on the blessings of trees, they can recover quickly.
This process doesn’t even take more than an hour.
It’s akin to a specialized version of the unique "Heroic Spirit Hall."
Although it might seem redundant, still, having a distinct life-saving ability is always good.
Moreover, the abilities concerning the soul don’t stop here.
One of the new abilities she gained with this promotion also relates to the soul and can complement the previous ability.
This ability is called [Tree Spirit Awakening].
As the name suggests, it is an ability like awakening Tree-men. She can awaken consciousness in a tree and turn it into a Tree-man, sharing the Transcendent Ability equivalent to her Rank 4 Pharmacist stage.
This awakened Tree-man can also serve as the basis for her resurrection, becoming a mobile Resurrection Anchor Point.
Combined, they are where this ability truly shines.
If Bai Yi had not developed her own "Heroic Spirit Hall", this ability alone would have resolved all her survival issues, leaving no concerns for the future.
Imagine if she deployed these contracted Tree-men worldwide, acting as globally roaming combat-capable Resurrection Anchor Points, how would one even begin to clear them?
Especially since this Resurrection Anchor Point can simply find a spot to settle down anytime by disguising itself as a tree...
Ah no, it is originally a tree, no need for disguise, even Jesus would be unable to dispute it.
This doesn’t even consider the scenarios within dungeon worlds...
If Bai Yi is willing, she could completely replace the function of dungeon tickets by committing suicide to traverse and transfer across worlds.
When the contracted trees are strong enough, or are even giant trees, the wear and tear on the plants during resurrection is not significant and within the bearable range.
This is way more convenient than setting up a Heroic Spirit Hall in that world.
After all, even with her personally hastening the process, growing a Heroic Spirit Hall from scratch starting with a Fungus Blanket takes half a month.
This doesn’t even include the need for subsequent periodic backups.
Compared to a large building, a tree is clearly much simpler to handle.
"It’s a pity, though, the contract has to be with fully-grown trees, and these mature trees are too large for other Lords to bring into dungeons.
Moreover, this contract also bears my mark, automatically marking it as my unit, preventing me from using this ability to directly invade worlds.
But at least, in the future worlds I conquer, I would no longer need dungeon tickets or dungeon permissions to enter or maintain control..."
Of course, this "Suicide Teleportation Method" can’t carry materials, otherwise, it would be overly absurd.
But being able to enter and exit dungeon worlds at will, this promotion is already worth the ticket price.
Moreover, this is only one new ability, and she has gained a second new Transcendent Ability and enhancements for her other abilities in this promotion.
This other Transcendent Ability also relates to Tree-men, allowing part of her body to plantify and inherit the abilities of the plantified plants.
She can even further transform herself on the spot into a Tree-man state merged with the contracted plant, complete with an aura that causes sanity...
