Foundation Establishment Dao Platform.

Apart from the first Dao Platform, the others are formed by accumulating vast resources and various heavenly materials and earthly treasures.

Spiritual energy and elixirs are easy to understand.

But when it comes to heavenly materials and earthly treasures, special methods are needed to refine and absorb them, drawing their essence into the Dantian Sea, transforming it into part of the Foundation Establishment Dao Platform.
