Suddenly, a calm and magnetic male voice came from Room 12.
In an instant, the entire auction venue fell into a dead silence like a wild storm.
Two middle-grade spirit stones!
Oh my God, someone actually offered two middle-grade spirit stones?
Although the exchange ratio between middle-grade spirit stones and low-grade spirit stones was one to ten.
All the cultivators knew that very few people would trade one middle-grade spirit stone for ten low-grade spirit stones.
That was because middle-grade spirit stones were much rarer than low-grade spirit stones!
Moreover, middle-grade spirit stones could even affect the training at the nascent soul stage.
Low-grade spirit stones were only useful to people in the refinement realm. At the nascent soul realm, absorbing the spiritual Qi from the low-grade spirit stones might even affect one's own strength.
