Special soldier Meng Xiao was accidentally reborn as the son of Qin general Meng Yi. The iron mark on his left shoulder conceals the secret of time travel. Faced with the Yin Gu used by Zhao Gao to usurp the country and the iron-making beasts invaded by the Huns from the south, he improved the Qin crossbow gunpowder with his left hand and awakened the blood of the black bird with his right hand, tearing history apart on the battlefield where Mohist institutions and Yin and Yang secret techniques intertwined. When the national jade seal seeps out the blood lines of "Hu, the one who destroyed Qin", he must make a decision: Should he repair his established destiny, or use modern thinking to recast the bronze civilization? This life and death game across the Central Plains and Guixu will usher in a cruel answer that transcends the times on the moonlit night when the flood engulfs Xianyang.
