While using an Illusion to deceive the dog into going to the hall, he specifically went to the Purple Summit Pavilion to find records and books related to the Dragon Horse. The Dragon Horse's original name was actually Huanshu, originally living in Dai Mountain; its entire body was a treasure, capable of curing all kinds of extraordinary poisons around the world.
Especially its horn, even the Medical King's elixirs had to admit defeat when compared to Ding Rui's singular horn. Any poison, needing just one touch, would immediately be neutralized. Moreover, for those who had already died from poisoning, simply soaking its horn in a bowl of water and drinking it could revive the dead.
