In the days that followed, besides attending class and cultivating as usual, Ning Wangshu also studied the remaining Dragon Summon in his possession.
If he wanted to find a way to let Lin Qingzhu, whose Primal Yin had already been broken, use Dragon Summon, he first needed to understand its secrets—and why it could no longer be used for a baptism once someone's Primal Yin or Primal Yang had been broken.
Only then could he come up with a suitable remedy or improvement.
However, the method used to refine Dragon Summon clearly hadn't come from an ordinary person. With Ning Wangshu's knowledge and current level of cultivation, he still couldn't unravel its secrets in just a few days.
After observing Ning Ruoxuan during their morning cultivation sessions over the past few days, Ning Wangshu discovered that her cultivation speed had indeed improved considerably.
As for Zhu Xiyan, he couldn't observe her now that he was back at school. Still, Ning Wangshu had called her to ask how she was doing.
According to Zhu Xiyan, she'd been cultivating almost twice as fast as before!
Zhu Xiyan had already been exceptionally talented, with an astonishing cultivation speed. To double it was remarkable.
Especially since she also had the Spirit Stones Ning Wangshu had given her to aid her cultivation, and was practicing Huang Tian Lu, a top-tier Cultivation Method that Ning Wangshu had chosen as the one best suited to her physique.
It was no exaggeration to say that, by now, Zhu Xiyan's cultivation speed was downright inconceivable to the ordinary cultivators on Earth!
Ning Wangshu had originally thought it would take Zhu Xiyan at least eight or ten years to reach the Golden Core Realm.
But now, it looked like she might get there in five or six years at most.
