The idea flashed in his mind, stirring He Song's heart.
Yes!
The time difference between his and Wei Fan's breakthrough to the Foundation Establishment Early Stage was just nine years.
When he broke through to the Mid-stage Foundation Establishment, he spent a full four years less than Wei Fan.
And when breaking through to the Late Foundation Establishment Stage, the time he spent was eight years earlier than the ordinary Foundation Establishment Masters.
His cultivation has now reached the Late Foundation Establishment Stage.
Based on this timeline and calculation.
Under such circumstances, the mana in Wei Fan's body is possibly quite full, and he might be experiencing the bottleneck of the Late Foundation Establishment Stage.
Perhaps, during this time he's secluded for cultivation, he is likely trying hard to break through this bottleneck?
However, it's uncertain how much time Wei Fan will need to spend, being blocked by the bottleneck.
