The Dayan Dynasty was founded eight hundred years ago and ruled the nine states. The royal family's surname was Ji. It was rumored that the thin "emperor's blood" flowed in the blood, which could suppress the immortal sects in the world. But in fact, the Immortal Sect has long been secretly evading the imperial power. The so-called emperor's blood is just a sacrifice raised by the upper world - every three hundred years, the Tiandaoyuan will harvest a royal family with the highest concentration of emperor's blood to stabilize the plane passage.
