Li Tingbai attracted everyone's attention when he was born. He was talented and prestigious, and was the perfect candidate for the throne.
He Zishu was born in Dunhuang, where the current situation was turbulent and many people chose to become a monk. He understood the true meaning of dance and music from the beautiful murals, and finally composed a piece of music that he was proud of and choreographed a world-famous dance.
Not long after Li Tingbai became the crown prince, he was deposed and began his life in exile. But the tragedy is far from over. An unknown mysterious force has been trying to kill him. He Zishu was also implicated and his whereabouts are unknown.
After escaping from death, Li Tingbai remained anonymous and relied on his own abilities and ruthless tactics on the battlefield to achieve many military exploits in Kang State and became the famous King of Dongping County.
The cavalry finally entered Chang'an City, and Li Tingbai met Ya Le again, but this time he changed his name to He Zishu. None of them were dazzled by the loss and recovery. He Zishu was willing to become the sword in Tang Changqing's hand. He only hoped to help him succeed and subvert the world.
When the dance music played again, the Tang Dynasty ushered in its fourth emperor. But where should the fate of the two go?
Intention: One is born with responsibility for the country, and the other is destined to survive in the chaos of war. A trick of fate caused the two to meet and get to know each other. When one day their identities quietly change, and the king is no longer the king, then who will control the next fate?
