At this moment, the Grotto World Pearl was undergoing dramatic changes.
Inside the Grotto World Pearl, the Spiritual Qi was increasing, its concentration so dense it was almost turning into mist, condensing into liquid, directly manifesting in the void.
As he entered the Grotto World Pearl, Lu Xuanji slightly frowned, feeling a bit uncomfortable, and couldn't help but cough.
Spiritual Qi is not necessarily better the denser it is; if its quantity exceeds a certain limit, it can cause discomfort to a cultivator, much like oxygen poisoning.
Activating the Grotto World Pearl, he adjusted the concentration of the Spiritual Qi, causing it to settle underground, and gradually, the concentration began to decrease. After some time, it finally returned to normal, just right for his stage of cultivation.
Sensing the underground Spirit Vein, he noticed it was subtly changing, surpassing the limits of a Seventh-Grade Spirit Vein, and beginning to transform into an Eighth-Grade Spirit Vein.
