After cultivating for several hours inside the World Pond, Xuan reached the Ninth-Layer of Flowing Qi stage while Yuxin reached the sixth. Naturally, their cultivation speeds differentiated, as Xuan had lots more experience and could absorb the abundant and rich World Qi of the small world directly into his body thanks to the Chaos Scripture.
Yuxin, on the other hand, had to cultivate like normal people—channel the Qi inside their own bodies, and slowly solidify it to become stronger. It was a painstakingly slow process, but she seemed to be quite talented at it, surprisingly enough. Xuan had already heard about her monstrous talent from Elder Shuang, but seeing her almost be able to keep up with him was still quite the sight.
