In the 46th year of the Dongting Dynasty, in March of the Kangxi year of Jin Min, the emperor was seriously ill. Sima Liang, the king of Runan, took the general's eldest son Sang Yunduan as a hostage and forced Sang Yu to lead his army. Sang Yu had to betray the royal marriage alliance and send troops to rebel. Thanks to Mrs. Xun's tip, Queen Xiabuhe was able to take the crown prince Sima Rui and flee to Lubu, the leader of the four tribes in the West Courtyard.
Unexpectedly, Sima Liang had already bribed Ge Erdan, the general of the Tiger Tribe, and Bile, the son of the Great Chanyu of the Wolf Tribe, and the two sent troops to strangle the queen on the way. Fortunately, the grassland eagles and deer arrived in time to save the then ten-year-old crown prince Sima Rui.
In the reincarnation of heaven, only three months later, Sang Yu was killed by Sima Liang, the king of Runan, and the nine tribes were punished for treason. His eight-year-old daughter Sang Yunchu escaped under the protection of his wife, sister Xun, and his daughter-in-law, Jin Jiuzhen, and lived in seclusion outside the customs. Unexpectedly, he met Shi Zhou Huozhu, the leader of the Steppe Wolf Tribe, who was looting the village. In order to save Sang Yunchu, Xun Shu committed himself to Shi Zhou Huozhu and became the Sihuan clan of the Steppe Wolf Tribe.
In December of the same year, Shi Zhouhezhu took the looted property and slaves to Lubu. Due to the heavy snowfall and the long journey, Xun Qin, who was pregnant and had a miscarriage, had to stay in Lubu.
They stayed here for four years. Xun Xun and Jin Jiuzhen were afraid that their identity would be revealed and they would be killed, so they had to disguise Sang Yunchu's daughter as a man and change her name to Yun Sang to hide her life experience. Yunsang grew up in Lucheng, and gradually lost her childhood innocence. By chance, he was sent to look after Sima Rui.
The story begins from here on, children in troubled times, old alliances, and whether the eyeless sky has already arranged a way forward for the destined people...
