"Nine Heavens Gang Wind Evil Qi, Jiuyou Profound Ming Evil Qi, Fierce Fire Sun Burning Evil Qi, Ice Corpse Cold Erosion Evil Qi... these Nine Flavors of Evil Qi are quite remarkable, just right to upgrade Zi Xiao's Co-Cultivation Magical Treasure."
Lu Changsheng looked at the main material of the black flag, his face showing delight.
