That's right, on the Backsword Grandmaster's stall, there was a peculiar stone emitting alluring energy.
However, people here didn't know what it was or how to use it, so nobody wanted it.
"What is this? Although it emits terrifying energy, it can't be absorbed."
"It seems a bit odd, but is it of any use? How much does it cost?"
Although people gathered around, none of them realized its value.
Let alone these onlookers, even the Backsword Grandmaster didn't quite understand it and casually gave a price: "Three pieces of Middle Grade Celestial Essence Stone."
Upon hearing this, Ye Feng was overjoyed.
Such a good treasure being sold for only three pieces of Middle Grade Celestial Essence Stone is practically giving it away for free.
These people didn't know the use of this stone, but Ye Feng did. In the Cultivation Realm, this is known as a Star Refining Stone, a gem that upgrades artifact grades.
