Chu Li already knew whatever Lin Yuanshan said.
Instead, he had already made modest gains, especially when Lin Yuanshan spoke about how the Emperor was like on a daily basis.
The Emperor was described as if he had no martial art skills, which was an odd condition.
While the other martial art masters could not do it, he was able to do it.
Normally, one's inner energy would be dissipated, leaving just a small trace for the cinnabar field. With a switch of thought, spiritual force would gush into one's body from all directions, transforming into tempestuous inner energy, which was the way of using the void of the universe as the cinnabar field.
For the Emperor to achieve that, his approach might be different from Chu Li's own. Usually, without using inner energy and with just a switch of the mind, he would be able to be possessed by God. Nevertheless, he could achieve peak condition instantly.
