Chapter 770: The Land of Ghosts
After the initial excitement faded, Qin Sang calmed down and fell into deep thought.
The Yan Luo Banner of Ten Directions was not something that could be refined at will, at least not with his current abilities.
The refinement of this astra required three distinct steps.
First, the black iron columns had to be melted and forged into the banner pole.
This process required the support of an extremely complex spiritual array.
Qin Sang had learned how to arrange this array from Yi Tianye. In addition to all sorts of spiritual materials, there was another extremely demanding condition: The array could only be activated using high-grade or top-grade spirit stones.
He would not dare to hope for top-grade spirit stones, but even high-grade ones were rare treasures. He only had two in his possession, which he had to reserve for using an ancient teleportation array.
He must always ensure that he carried two high-grade spirit stones at all times.
Based on his decades of experience, high-grade spirit stones were even rarer in Canglang Sea than in the Small Cold Domain.
The higher the quality of the spirit stone, the more powerful its effect. No major faction ever had enough.
In the Small Cold Domain, when ancient ruins from the Ancient Immortal Battlefield emerged, the first cultivators who entered might find a few if they were lucky. A small number would make it to the market, and with effort, it was still possible to buy some.
In Canglang Sea, high-grade spirit stones mostly came from spirit stone mines. The few existing mines had long since been occupied by major powers. Any stones excavated were immediately claimed and stored away, with almost none ever reaching the outside world.
