Progressing from the Foundation Establishment Phase to the Nascent Soul Stage, even with the proficiency that Li Fan has now, would take quite a bit of time.
Moreover, the things he's been encountering are becoming increasingly dangerous. It's uncertain what obstacles he might face during this process, which would be difficult to handle in the Foundation Establishment Phase.
Therefore, it was only logical that Li Fan wanted to set new anchor points.
"If everything goes as planned, perhaps before the end of this world, I might be able to take advantage of the interval when the Faceless True Immortal is contending with the Deserted Dao Immortal to frenziedly extract Xuan Huang and achieve the God Transformation Realm during the Change of Life," Li Fan thought.
"In the future lives, starting with a cultivation level that rivals the Immortal Realm as a baseline, any scheme would be much easier to accomplish," he mused.
