The Fourth Layer is the stage of cultivating Qi Blood.
Lin Zheyu, in the Qi Blood Realm, has already surpassed the Qi Blood Dragon Realm, reaching the stage of the Fifteen Transformations.
Upon entering this level, the progress of the Fourth Layer of the Infinite Jade Waves True Skill immediately increased to one hundred percent.
However, it's still early to completely cultivate the Infinite Ocean Body.
To thoroughly cultivate the Infinite Ocean Body, one must allow the medicinal power and Qi Blood to penetrate the bone marrow when the Martial Dao is integrated into the bones, completely changing one's aptitude.
If one alters their cultivation of this technique after the Bone Marrow Refining Realm, the difficulty of cultivating the Infinite Ocean Body would increase greatly.
Not only would strong aptitude and comprehension be needed, but also much more time and effort.
Luckily, Lin Zheyu is still only at the Qi Blood Realm stage.
