"Master, what is this?" Wan Mingchuan had never seen such a beautiful stone before.
It was walnut-sized, round and flat, slightly cool to the touch, and emitted a soft blue glow that was quite gorgeous.
Jiang Yuan, bound to the system, was completely out of sync with regular cultivators and couldn't feel the so-called spiritual energy within it. He could only reply according to the system's analysis: "This is a Spirit Stone, an essential item for cultivators. It can be used to buy things or absorb the spiritual energy within it to enhance your cultivation. In the human world, where spiritual energy is scarce, your cultivation speed will slow down during the day. Using Spirit Stones to directly absorb a large amount of spiritual energy can greatly improve your cultivation efficiency."
A Spirit Stone? And it can be used to buy things? Isn't that just money for cultivators?!
