The two of them were practicing dual cultivation in the cave.
The spiritual energy in the cave was already quite dense, but thinking of the high realm of the Outer Realm Cultivators, they decided it was crucial to enhance their strength, so they took out the spirit stones they had excavated along the way to aid their cultivation.
In this way, with the support of dual cultivation and the continuous supply of spiritual energy from the spirit stones, the two could clearly feel the increasingly high efficiency of True Qi transformation within their bodies.
Originally, after entering the Foundation Establishment Stage, the total amount of True Qi stored within their bodies reached a considerable level, and now, with continued cultivation, the True Qi was becoming more and more abundant.
It was clearly felt that the True Qi stored in the Dantian was increasing, and at this rate of cultivation, it might take only a year or so to fill the Dantian with True Qi.
