"Just like in the legends, Tree Elves can transform among four states: Treefolk, Tree Elf, Tree Spirit, and Elf,"
Very soon, Grandfather Andrew changed back into his elf form.
Seeing Grandfather Andrew complete this series of transformations relieved the other Tree Elves.
"So we can change back."
"Let me try."
"Ah, it really did change back, yay!"
The Tree Elves had originally been very anxious since they had long been accustomed to the appearance of elves.
If they suddenly changed into something else, they truly wouldn't be used to it in the short term.
Fortunately, this power could be controlled freely.
And as it turned out, the reason Grandfather Andrew could so easily alternate among the four states of Treefolk, Tree Spirit, Tree Elf, and Elf was that he was very strong to begin with.
If it had been the other Tree Elves, especially the children, they could only maintain the Tree Elf form halfway.
Which is to say, their buds were ready to bloom but unable to unfold.
