Situ Xin knew that Xiao Muli already had her Spiritual Energy within him and that they had been intimate. Even if he previously had no Spiritual Root, by now, it must have been improved to the best state imaginable. Therefore, Situ Xin and Baibai didn't bother having him test for a Spiritual Root. Instead, they simply took a Cultivation Technique from Baibai and handed it over to Xiao Muli, letting him figure it out on his own.
And boy, Xiao Muli's Cultivation speed was indeed impressive. After Situ Xin had explained the matters of Cultivation to him, she let him take the Cultivation Technique and try to comprehend and cultivate it within the spatial realm. To her surprise, when Situ Xin woke up from a nap, she saw that Xiao Muli was completely transformed, having reached the Qi Cultivation Second Layer in a blink of an eye and was on the verge of breaking through to the next level.
