Rui's eyes lit up as he heard a maternal voice speak in his head, just as the Elder Tree did.
Before, he didn't have any idea how that used to function, but now that he was a Martial Sage, he could tell that it functioned with projected electromagnetic waves that caused certain neural activity in one's mind.
The Mother of Nature that he beheld at the very epicenter also relied on this to communicate directly in his mind, bypassing language and conveying information directly.
"You must be Mother Alicia," Rui replied as he studied the astronomically titanic tree. "It is a pleasure to meet you."
It wasn't just a cursory pleasantry, either.
It truly was an incredible experience to behold the Mother of Nature this close in all her majesty and power. Her roots dwarfed mountain ranges as the height of her tree seemed to reach outer space with just how utterly titanic it was. The sheer mass and volume that comprised her being were beyond unfathomable.
