Yuan Mobai, taking into account Lei Jun's current root bone, comprehension, and state of mind, had once made a general estimation.
If there were no other external influences, Lei Jun would need about a year to advance from the initial stage of Foundation Establishment to the intermediate stage.
It would take about three years to move from the intermediate stage to the high stage of Foundation Establishment.
From high stage to Foundation Establishment Perfection, it would take about six years.
In other words, all told, it would require about ten years to go from the beginning to the peak of Foundation Establishment Realm.
The Three-layered Heaven Dharma Platform Realm differed from the First Heaven Layer's Twelve Floors and the Second Heaven Layer's initial, intermediate, high, and perfection four stages.
