Ji Wei, a daughter of the Mohist family, disguises herself as a man and steals classics. She has a sword fight with the cold and stern Imperial Lieutenant Zhao Han, but reveals the secret of the dragon wall because of her twin blood. From hostility to life-and-death agreement, the two of them broke through the Yin and Yang family's conspiracy in the Guan City and Lishan underground palace, and solved the mystery of the Qin family's life experience. Zhao Han broke his arm to protect his love, Ji Wei's blood sacrifice broke the situation, the gears are the contract, the mountains and rivers are the evidence, the sword edge and the mechanism dance together in the chaotic world. The Mohists' ambition to love without attacking eventually turned into a passionate legend of two souls united in their hearts. When fate turns into a cocoon, they prefer to use love as a blade to cut through the shackles of thousands of years, and guard the eternal peace of the mountains and rivers where the moon returns to their hearts - the world is rewritten because of the twins sharing the same fate!
Purpose: Using the troubled times of the Qin Dynasty as a mirror, we can see the fire of civilization inheritance, the crisis of power alienation, and the power of individual awakening. The twin contract is not only the bond of blood, but also the eternal game between civilization and tyranny, freedom and destiny, love and selfish desire. It ultimately points to the Eastern philosophy of "mountains and rivers as evidence, and the bright moon as the center" - the great unity of the world begins with the unity of people's hearts.
