After leaving, Yang Xiaotian went to the Academy's Book Pavilion.
Since only one secret tome could be borrowed at a time, Yang Xiaotian chose the "Phantom Sword Technique" this time.

Previously, Chen Bingyao had used the Phantom Sword Technique for his second challenge against Yang Xiaotian.
Seeing Yang Xiaotian taking the Phantom Sword Technique and leaving, Hu Xing's face darkened.
"I didn't expect Yang Xiaotian to actually cultivate Sword Thirteen to the Perfection Realm," Cheng Beibei said with a furrowed brow, watching Yang Xiaotian's retreating figure.
"Sword Thirteen is just an Acquired Martial Technique. So what if he has perfected it?" Hu Xing scoffed with a sneer. "In a year, if he doesn't break through to the seventh rank, he will have to pack up and leave just the same."
