As Ye Xiao's Divine Sense and Spiritual Energy operated, all the Spiritual Medicines and Spirit Pills within the Rebirth Ring were taken out by him.
Among these, a portion was the Spirit Pills he had harvested in the land of weeping immortals, the spiritual energy in which was rather immense, but their specific effects were unknown to him.
Of this type of pill, Ye Xiao only retained a few of the most potent ones with the strongest spiritual energy inside the Rebirth Ring, taking out all the rest.
In the world of cultivation, there aren't only Spirit Pills but also poison pills.
Those who practiced poisoning would mix their toxins with Spirit Pills abundant in spiritual energy for others to consume.
This was not an uncommon thing in today's cultivation world, and it was even more so in that previously prosperous age of cultivation civilization.
