Chapter 155: The Grades of the Celestial Essence Stone
Indeed, from these four cultivators, Ye Feng harvested a large amount of Celestial Essence Stones.
That’s right, Celestial Essence Stones that can extract Spiritual Qi for cultivation, these things are indeed good stuff.
Moreover, the Celestial Essence Stones on them seem different from those that Ye Feng obtained before.
So, Ye Feng took one, and asked the conscious middle-aged man, "What is this?"
"Celestial Essence Stone, haven’t you seen it before?" After being disciplined by Ye Feng, this guy became much more honest and answered respectfully.
"Then why is it different from the ones I saw before? The ones I saw before were light green, this time the color is much darker." Hearing the other’s reply, Ye Feng frowned and asked.
"This is a Middle Grade Celestial Essence Stone, the ones you saw before must have been Low Grade Celestial Essence Stones." Hearing Ye Feng’s confusion, the other quickly explained to Ye Feng: "Actually, these are very easy to recognize."
"Low Grade Celestial Essence Stones are light green, Middle Grade Celestial Essence Stones are green, and Upper Grade Celestial Essence Stones are dark green, while Top Grade Celestial Essence Stones are dark green."
"These Celestial Essence Stones are graded? Then how is the exchange?" Hearing the other’s explanation, Ye Feng was relieved.
He did feel that the energy level inside these Celestial Essence Stones was much richer than before, so they were indeed a higher grade of Celestial Essence Stone.
Seeing Ye Feng’s interest, the middle-aged man explained in detail: "One Top Grade Celestial Essence Stone can be exchanged for ten Upper Grade Celestial Essence Stones, which can be exchanged for a hundred Middle Grade Celestial Essence Stones, and can also be exchanged for a thousand Low Grade Celestial Essence Stones."
