Heavenly Fairy God Scripture, the primordial energy cultivation technique of the Heavenly Fairy God, was tailored for members of the Wood Spirit Race like the Heavenly Fairy God himself.
For Faelyn, who is part of the nature-blessed elf tribe, she could be considered a descendent of the Wood Spirit Race.
The Wood Spirit Race was one of the superior races in the primordial era. And their kin varied from humans, sub-humans, beasts, and even monsters.
Any living being could be a part of the Wood Spirit Race. The only prerequisite was to be supremely blessed by the wood element at birth.
Although the elven race was blessed by the wood element, they still couldn't be compared to the true Wood Spirit Race from the primordial era.
As such, they can only be considered descendants or a branch of the Wood Spirit Race at best.
