It Seems Father Didn’t Train You Properly [Half R18], Karma

The formation of Heavenly Palace during breaking through from Foundation Establishment to Golden Core was the most important part of the Golden Core stage.

Most Cultivators were stuck in Foundation Establishment stage for a long time because once they form their core, their future achievements would depend on the size of the Core and Heavenly Palace.

Usually, one would try to expand their Foundation Platform as much as possible before forming their Core because after forming one's Core, they only needed to absorb Spiritual Energy to continue to advance.

...

When Lucian broke through to the mid stage of Golden Core, his Spiritual Energy became more pure and dense than before, raising his battle prowess even further!

Moreover, after breaking through, his Qi Sense range also increased nearly twofold!

He could now cover the entire royal capital with it!
