That is another symbol of the Foundation Establishment Stage, besides Spirit Consciousness Release - Spirit Power Liquid Transformation.
Only with the Spirit Power Liquid Transformation can a True Cultivator of the Foundation Establishment Stage execute various powerful techniques, and even control top-grade magic tools, even magic items to some extent.
Luo Chen's Spirit Liquid isn't much.
But this is not all he has.
Within his first level Sea of Qi, there still lay a large amount of Spirit Qi cloud clusters.
That is the residual gain after taking five portions of Foundation Establishment Spirit Medicine.
No matter it's the wildly potent Foundation Establishment Pill or the milder Emperor Liquor, the spirit Qi they contain is immensely vast.
Luo Chen, within a short period, has attempted the Foundation Establishment Stage several times, there surely would have been instances where he couldn't utilize them properly.
Now, all of them remain within his freshly opened Sea of Qi.
