Having learned from the Azure Flood Dragon King, who had lived for who knew how many years, about the divisions among spirit treasure grades, Li Qing's heart surged with longing.
So above Yellow-grade Spirit Treasures, there were three more grades. Only a Heaven-grade Spirit Treasure deserved the four words "Heaven-Piercing Spirit Treasure."
Just how powerful would such a spirit treasure be?
Li Qing found it difficult to imagine. After all, relying on the Wind Thunder Silver Wings he had forged himself, he had slain who knew how many foes of the same rank, cutting through all opposition without a setback.
If it were an even stronger Mysterious-grade Spirit Treasure, Earth-grade Spirit Treasure, or that so-called Heaven-grade Spirit Treasure, just how terrifying would its might be?
Li Qing did not continue pondering it. Those matters were still far too distant from him.
He liked to keep his feet on the ground and rarely did things that aimed too high.
