"Nine hundred!"
Luo Tian made his bid, suppressing the excitement in his heart.
There were only two ways to advance his Divine Vein.
One was a gradual enhancement along with his Cultivation.
The other was through external items, which were extremely difficult to come by.
Aside from the potent poison Liu Ziyan had once used on him, this was the first time Luo Tian had encountered a precious material that could enhance his Divine Vein Power.
The starting bid was six hundred.
When Luo Tian announced a price of nine hundred, some of the competitors hesitated slightly.
Although the Yin Crystal Stone was rare, the demand for it wasn't very high. In the Azure Cloud Kingdom, those who practiced Dark Attribute Techniques were not in the majority.
"One thousand."
A cool, deep voice called out.
