Both Spirit Beasts had reached the stage of breakthrough, so from then on, Li Zhirui didn't need to be by their side constantly, for barring any unforeseen circumstances, this breakthrough was unlikely to result in failure for them.
It is worth noting that Li Zhirui intentionally chose locations for Da Qing and Xiaoqing's seclusion that were far apart from each other to minimize any interference they might cause each other.
As a result, he returned to his previous routine: cultivating, alchemy, and occasionally offering guidance to the younger generation of the Li family.
Among them, Li Mingyao shone the brightest. Barely in his teens, he had already broken through to the late phase of Qi Cultivation. Had it not been for Li Zhirui advising him to patiently refine his foundation, he might have already reached Foundation Establishment.
