In 212 BC, the young master Fusu was sent to the county for his direct remonstrance. Two years later, the first emperor died in the sand dunes. Zhao Gao and Li Si issued an edict, ordered Fu Su to die, and massacred everyone in his family. Only the infant son Nan Si was secretly rescued by Zhongwei Mengxin, and he and his wife Han Ya taught him earnestly.
More than ten years later, the Han Dynasty was established. Meng Xin cherished the ambition of restoring Qin, and took Nan Si to join the Seven Star Alliance formed by the descendants of the six countries. Nan Si served as the head of the "Fu Qin Hall". The leader of the alliance, Xiang Di, is the grandson of the King of Chu. The two of them share the pain of losing their country and cherish each other. Nan Si and Meng Xin's daughter were childhood sweethearts in the Qin Dynasty and fell in love like brothers and sisters. Unexpectedly, they met Cai Wei, a princess of the Han Dynasty. There is an orphan from the Qin Dynasty, and a golden branch from the Han family. The hatred of the country and the family runs between them, and there is a secret love.
During an anti-Han operation, Caiwei fell into the hands of Xiang Di. Xiang Di was also moved by his beauty, and the three of them were entangled in love and evil. Later, because members of the Seven Star Alliance killed innocent people, Nan Si left the alliance in anger and joined the army, serving as a general. However, Xiang Di was deeply obsessed with the dream of restoring the country and surrendered to the Huns. The iron hoof moves southward, destroying all life. Fortunately, his conscience was not lost, and he finally abandoned the dark side and surrendered to the Han Dynasty.
Meng Siqin wanted to assassinate Caiwei out of love and hatred. Xiang Di and Nan Si understood his plan and protected him secretly. In the melee, Xiang Di sacrificed his life to protect each other and was seriously injured. Siqin felt guilty and took turns taking care of Caiwei, and the two gradually resolved their past feud. After Xiang Di experienced the world, he put aside his obsession with picking Wei and turned his attention to Si Qin. Nan Si also settled the old grudges with Xiang Di.
In the end, the orphans of the fallen Qin and the remaining members of the fallen Chu put aside their grudges and returned to the Han hand in hand. The descendants of the Six Kingdoms are invited to return, and the world returns to its heart. The lights in Chang'an are like daylight, Nan Si marries Cai Wei; Xiang Di and Si Qin also get married. It can be said that when the country is destroyed and the family feud ends, the right path in the world will be vicissitudes of life.
