After returning to the Elder Tree's crown, Leon communicated with the Guardian Spirit to resume its journey.
With the current situation outside, even if the flaming rat walls collapse, it would still be a sea of fire that the rat tide would not cross to reach the elves.
Nevertheless, Leon made the Guardian Spirit take a different path.
"You want to use the Elder Tree to mow down the rat tide?"
Duna quickly guessed Leon's intention before he nodded.
"That's right. Might as well utilize this big girl to the fullest," Leon said while patting one of its big branches.
"Oh? The Elder Tree is a girl?" Duna asked with surprise before adding, "I didn't know trees even had genders."
"Oh, but they do. Trees are divided into four genders, in fact. Some trees can even change their genders as well, going from males to females," Leon explained with his wealth of knowledge on plants and herbs.
