The "Xi He Flower" that grows in the Tang Valley Sea absorbs the brilliance of the Fusang Divine Tree and the Golden Crow year-round, eternally blooming. If it is not considered the supreme Yang flower, Li Weiyi truly does not know what miraculous thing exists in the world. For this reason, he once asked his knowledgeable master, the coffin master.
The coffin master had seen records about the Xi He Flower in the ancient texts of the Nine Li Tribe, describing it as a rare ancient medicine, but it contains terrifying fire poison that can burn a martial practitioner's flesh.
Only some top-tier pharmacists, using ancient secret formulas, can regulate the fire poison of the Xi He Flower to refine it into exquisite elixirs. However, this processing is extremely delicate, and ordinary pharmacists would not dare to attempt it. This is the case for humans!
For the monster race, the Xi He Flower is a legendary transformative medicine; they are not afraid of its inner fire poison and it can only be encountered by chance. Li Weiyi had the thought of helping Yao Yin pick the Xi He Flower only after learning that she had the bloodline of the monster race.
