Spirit didn't think that after receiving the Vitality, the extent of Zhao Xuanqi's power boost could compare to hers. Even though he was from the Infinite Dao, and his body was fundamentally much stronger than this body of Zhuang Li's—theoretically able to contain even more Vitality.
'But theory is just theory. From her interactions with him, she could tell that Zhao Xuanqi probably wasn't from the Upper Realm. Instead, he likely traveled between worlds using some method left behind by the Infinite Dao. His previous cultivation level and consciousness were most likely inferior to hers, and he might have even come from a weaker world. Even if he suddenly obtained immense power, he would have great difficulty wielding it.'
'Therefore, all things considered, after absorbing the Vitality, Zhao Xuanqi would be on par with her at best. An opponent she found troublesome should be just as troublesome for him.'
