If he just wanted to achieve a normal Body Refining Core Formation, then Du Youqian could continue cultivating like this and probably form his Core in twenty to thirty years. Then it would take a hundred years to reach the Golden Core Middle Stage, and another hundred-plus years for the Golden Core Late Stage.
But did Du Youqian want to achieve a normal Body Refining Core Formation?
No. He wanted to achieve a Body Refining Core Formation that could survive the passage connecting the two realms.
That passage was filled with spatial rifts and sandstorms that could swiftly erode the flesh of ordinary Core Formation Cultivators. It was a channel rife with death, and even now, the thought of it made Du Youqian's heart pound with fear.
Therefore, he needed to continuously build his foundation during the Foundation Establishment Stage and after Core Formation, pushing his Body Refining to its absolute limit and achieving a perfect promotion at every stage.
