When the song of Chu spread across the Wujiang River, Yu Shu looked at the cinnabar tear mole in the mirror, and was shocked to realize that time travel was not a joke - she became the concubine Yu who was destined to die for her love in the history books. And her best friend Lu Zhi, who used to sleep with her, was standing in Lu Gong's mansion. She was named "Pheasant" and walked step by step towards the future Empress Lu.
From the university campus to the war between Chu and Han, they once crowded on a 0.9-Meter dormitory bed and imagined history, but now they have to live in the real light and shadow of swords, one drinking sword with the overlord, and the other pursuing power with Liu Bang. In the beginning, they were the only ones to rely on each other, exchanging modern memories in private meetings late at night, and using scientific thinking to dismantle military strategies; but when Lv Zhi's ambition grew wildly in the power field, when Yu Ji's compassion was entangled with Xiang Yu's fate, the friendship between best friends could not withstand the inertia of history books and the opposition of positions.
Love and killing are pulling between the Chu, He and Han worlds. They are the best confidants and the most ruthless opponents. Until the snow fell in Wujiang River, Yu Shu held the blood-stained sword and looked at Lu Zhi standing high in the Han camp, and suddenly understood: some endings cannot be changed, but some people can go home with her. Where the river flows back, two thousand years of time are folded, and their story is both a disaster and a journey.
Concept: What would happen if a pair of best friends traveled through time as Yu Ji and Lu Pheasant and became old enemies?
