In the underground cave a hundred miles deep, Lu Yan finished his cultivation slowly, his gaze sweeping over the pile of Spirit Crystals beside him.
Hundreds of Spirit Crystals scattered throughout the underground cave, their original pure white color now turned gray, the pure Spiritual Qi within them long since depleted.
In the ruins of the Cave Profound Blessed Land, Spirit Veins were destroyed, and rules were incomplete, so there was no sufficient Spiritual Qi to support daily cultivation. Therefore, Lu Yan could only consume the Spirit Crystals brought from the Xianxia version.
Compared to the vast Spiritual Qi between heaven and earth, hundreds of Spirit Crystals could almost be ignored, but Lu Yan didn't expect to rely on Spiritual Qi to break through the Cultivation Realm.
His strength improvement came entirely from another aspect.
