Zhao Xuan was a prince of the Jing Dynasty. He was born with a frail body and was judged not to live past the age of twenty. Unwilling to be reconciled, he accidentally obtained an evil ancient book and discovered that he could extend his life by absorbing the life essence of others. The external manifestation was a "rainbow"-like light and shadow effect. In order to survive and compete for the throne, he started by sacrificing prisoners on death row, and gradually extended his claws to masters of the world, court officials, and even his brothers. In the name of "helping people ascend", he actually practiced "hunting to survive", becoming a terrifying shadow hanging over the entire dynasty.
