When people are in Tianyuan, they cultivate and adjust their breathing, and naturally there is Spiritual Energy nurturing inside their bodies. However, in the Star Domain, there is no Spiritual Energy. Although they have reached such a realm where their bodies are transparent, as long as they would not die, Mana will naturally generate in their bloodlines, yet the speed is much slower than in Tianyuan. Thus, how to replenish Mana in the Star Domain becomes critically important, especially since the Star Domain is full of countless dangers. So, no one dares to be careless, generally ensuring their Mana is always at its peak. If they consume some, they immediately supplement it. For this reason, Spirit Stones become essential resources for their daily needs!
In a sense, Spirit Stones are as important to the cultivators in the Star Domain as food is to ordinary people!
