After a cultivator breaks through to Foundation Establishment, the spiritual sense in their sea of consciousness naturally transforms into divine sense.
The so-called divine sense encompasses the character "god," making it far more profound than spiritual sense.
The most straightforward change is that divine sense is imbued with power, allowing interference with reality, controlling objects from afar. With just the power of divine sense, one can command a sword to soar into the sky and transform strands of hair into swords.
After reaching Foundation Establishment, the need for cultivation with a Sword Seal requires a Spirit Sword as a carrier, primarily because cultivators possessing divine sense can ride the sword, uniting sword and technique.
A Qi Refining Cultivator, if wishing to wield a sword, can only do so through Qi control, which is not on the same level of profundity. Instead, they directly condense Sword Qi using a Dharma Seal to harm opponents.
