A day later, Hilda sat cross-legged as powerful Qi was emitting from her as well as grayish waves were rising.
At this moment, Hilda wasn't aware of this because her mind was fully immersed in a gray space which has a sun-like gray core in its center, and right now, it was trembling uncontrollably as if something wanted to burst out of it.
This was her prim Dantian, and in the middle of it was the Qi core she had created when she achieved the Qi Core Realm.
The Qi core has three stages Early, Middle, and Late, which directly represent the three states of this Qi core. At the early stage, the Qi core has a gas state. In the middle stage, it turned into liquid, and then at the late stage, it would be condensed into a solid state.
Typically a Qi core has no color, but it was only true for those who hadn't cultivated in unique element paths from the very start, and this brought nothing but tremendous benefits.
