Everyone knows that for a cultivator to progress from Qi Condensation to Core Formation, they must refine a core within their Dantian.

However, not all Qi Condensation cultivators have the aptitude for Core Formation. Most, if they can reach the level of Li Yuande, are already quite remarkable.

After reaching the Qi Condensation Twelfth Layer, those unable to form a core but still seeking to enhance their combat power often turn to alternative methods.

The Blood Core is one such path, but it belongs to the demonic way.
