Generally speaking, a cultivator relies on spiritual energy for cultivation, meditating to absorb the spiritual energy, allowing it to enter the body, circulate throughout, and refine through the meridians into the Dantian or Qi Sea, forming Inner Essence. This is a process of cultivation.
In Fang Yu's palm, there is True Spirit Energy.
In other words, he no longer needs to convert spiritual energy into Inner Essence. He just needs to absorb the spiritual energy and change its purity.
This greatly shortens the cultivation process and enhances the cultivation speed.
Even a cultivation genius couldn't achieve this level.
Fang Yu achieved it.
