Song City was transformed in a short month and a half. Everyone from simple Body Refining Realms to the few Immortals at the upper echelons of society had suddenly had remarkable improvement in their cultivation.
It was not a new pill or elixir, but training methods. Foundations that had suffered under the Corruption were made far better. Grasping the elements and a shift in how to balance them in the dantian fought back far better than anyone could have imagined!
Alchemists and elixir masters had their very foundations shattered at the same time. The methods of extracting herbs and other resources far more efficiently than ever before. Further, other professions were able to extrapolate a lot of it for their own purposes.
The orphanage that supplied children to aid them also suddenly exploded with potential unlike anything anyone had seen since the founding of the city!
