The Xiongnu royal family Luo Tanlie was reborn on the eve of the decisive battle between Han and Hungary with the "Hegemony System", vowing to reverse the defeat of the grassland and crush the dignity of the Han family with iron hoofs; Kunmomu, the prince of Wusun, was mysteriously reborn as a koi carp in the Chang'an swamp, bound to the "Lingze System", and quietly influenced the situation of the Han Dynasty with his auspicious luck. One is waving his whip in Mobei, using killing and strategy to restructure the grassland order; the other is waving his tail in the deep palace, using good omens and metaphors to touch the pulse of the empire. When the wolfish cavalry meets the soft waves of the koi, when the flames of revenge collide with the wisdom of survival, the two souls who bear the fate of the tribe will eventually set off a storm across the grasslands and the Central Plains under the sunshine of the Han Dynasty.
