"Given how dense the Spiritual Qi is here, there's a high chance a Superior Spirit Vein is hidden nearby. Otherwise, the Spiritual Qi wouldn't be this rich!"
The Black Dragon sensed the density of the Spiritual Qi in the Secret Realm. Even ten thousand years ago, this level would have been considered quite good.
Spirit Veins are the source of Spiritual Qi; any place with one will have a high concentration of it. Furthermore, Spirit Veins are born from Divine Veins.
Back when the Taiyu Divine Continent still had Divine Veins, places with Spirit Veins were numerous and perfect for cultivating Spirit Medicines and Spirit Grass. But as the Divine Veins vanished, these lands also began to slowly dry up. Long-lasting Spirit Veins are becoming rarer and rarer.
