After carefully weighing his options on Soul Resting Slope, Lincon finally chose his original Undead Soul Tree at the summit as the target for Potential Unleashing.
In truth, he had only used Seed Mark to advance three Undead Soul Trees at the beginning. Who could have imagined they would reproduce so quickly?
Unlike ordinary C-rank spirit plants, Undead Soul Trees were different. C-rank spirit plants generally had fairly long growth and reproductive cycles, and some even struggled to reproduce, so most spirit plants in Longwind City were D-rank or E-rank.
The Undead Soul Tree, however, was an exception.
Once mature, it did not need to scatter seeds. Instead, it reproduced through dead souls, living in symbiosis with them to produce offspring.
Thus, every tree that grew on Soul Resting Slope housed one or more human souls.
The Undead Soul Tree kept its symbiotic human souls from dissipating, while the humans helped it grow. In as little as a few months, or a year at most, an Undead Soul Tree could grow from a sapling into a mature tree.
Lincon gazed at the old, crooked tree before him and pressed his palm against it.
Golden light flashed as Potential Unleashing activated.
