"More surging?" Xiao Yi exclaimed lightly.
Qing Lin instantly reacted, "No wonder you said it's unusual, these are Mid-grade Spirit Stones."
"Mid-grade Spirit Stones?" Xiao Yi looked puzzled, a flash of light appeared in his hand, revealing a spirit stone.
Xiao Yi sensed it for a moment.
Indeed, the spirit stone in his hand was far inferior to those on the ground.
Qing Lin glanced at the spirit stone in Xiao Yi's hand, saying, "What you have is a Low Grade Spirit Stone."
"Are there different grades of Spirit Stones?" Xiao Yi asked in confusion.
"Of course." Qing Lin answered, "Spirit Stones are graded based on the purity and amount of Spiritual Energy they contain."
"The most common are Low Grade Spirit Stones."
"As everyone knows, a Low Grade Spirit Stone is enough for a Heavenly Extreme Realm Martial Artist to use for a month."
"And Mid-grade Spirit Stones are much rarer and much more potent."
"As for why you didn't know, it's simple, your level hasn't reached it yet."
