The little girl told him that she wanted to go to Jing'an Hall.
Because Jing'an Hall teaches many combat and offensive spells, making cultivation more aggressively progressive.
The little girl said she wanted to become a capable cultivator—just like when she witnessed Wang Guishan slaying the evil demon, that figure.
Wang Guishan felt somewhat uncomfortable deep down because... that demon-slaying incident was the first time he ever engaged in combat.
He was inherently someone who disliked conflict.
But the little girl also told Wang Guishan that she wanted to enter Jing'an Hall because it was easier to earn merits there. Accumulating merits could help increase her disciple level, allowing access to the Sutra Pavilion to exchange for superior cultivation techniques and divine skills...
She wanted to climb higher—Wang Guishan understood.
"Brother Guishan, I want to become someone who can stand by your side, someone worthy of you."
