Additional reasons above.
Then there's the point that makes Xu Chang'an truly feel it's possible.
He and Miss Yun are completely clueless when it comes to Yin Yang Dual Cultivation, after all, since Miss Yun always maintains her calm demeanor, he hasn't been able to gather any extra knowledge.
And Li Zhibai also doesn't understand, which is why he came down to ask Zhu Pingniang for guidance.
Thus the problem arises, among Muyu Peak, no one understands the Yin Yang Dual Cultivation Technique better than Zhu Pingniang.
When he eventually starts to cultivate with Yun Qian, if he encounters any detours on the Spirit Road, he'll need someone to consult.
Could he possibly ask Li Zhibai at that time?
Therefore, seemingly unpretentious, Zhu Pingniang is the best choice, and when considering living amidst the nosy crowds in Beisang City, being under Zhu Pingniang's watchful eyes is a far better option.
