In the Dajing Dynasty, the court was in turmoil, princes were vying for the throne, and there were many sects in the world. Among them, "Tinglan Pavilion" (specialized in medicine and poisoning, living in seclusion in the south of the Yangtze River), "Shadow Pavilion", and "Qingyun Sect", the three forces check and balance each other.
Twenty years ago, the Tinglan Pavilion was exterminated because of holding the "edict of the late emperor". Only the young master survived, but he lost his memory and lived among the people; the master of the Shadow Pavilion was actually an eyewitness to the Tinglan Pavilion's extermination case, and was the only one who could reverse the case for Tinglan Pavilion; the young master of the Qingyun Clan was the illegitimate son of the late emperor, with the mission of "finding out the truth about the extermination of the Tinglan Pavilion and preventing the prince from competing for the throne."
