The story takes place in a parallel world. At the execution ground in Handan, blood stains the flagstones. The nine-year-old Qin hostage, Zheng, falls beneath the brutal blades of the people of Zhao while protecting his childhood friend, Yan Dan.
When a soul from the future opens its eyes in Yan Dan's body, it looks at the young boy's lingering warmth and unfinished ambition, then suppresses the bond Yan Dan feels toward his homeland.
From that day on, he takes the name Ying Zheng, wields the emperor's sword, and strides through the flames of war in the Warring States period. He will fulfill the destiny of sweeping across the Six States and unifying the realm on behalf of the boy who gave his life to save him.
He will establish a new Great Qin Empire and rewrite his fate.
In his chest beats Yan Dan's heart, along with Ying Zheng's undimmed passion.
From this day forward, Yan Dan no longer exists.
There is only Ying Zheng.
He will live on in Ying Zheng's place, escape Handan, return to Xianyang, and seize the supreme power of the empire. For that nine-year-old boy, he will conquer the Six States and unify the realm, establishing an unprecedented, magnificent Great Qin Empire.
He will make history remember that Ying Zheng did not die at the execution ground in Handan.
In his hands, the Warring States era of this parallel world will shine with a different light.
The color of the bluestone in Handan is the end of the nine-year-old Qin Zhizheng, and it is also the beginning of a fateful journey across identities. He suppressed the ties to the homeland of the prince of Yan State, held the sword in the name of Yingzheng, and traveled through the war-torn times of the Warring States Period. This is not a simple time travel and rebirth, but a dislocation of identity, the inheritance of fate, and the continuation of passion - the body belongs to Yan Dan, and the heartbeat belongs to Yan Dan, but what burns in the chest is the unified blood of Ying Zheng Weiliang, and the firm obsession of the soul from another world after understanding the boy's annals. Based on parallel time and space, the author uses a execution ground to exchange souls, breaking the established trajectory of history, and giving the mission of "sweeping Liuhe and building the Qin Dynasty" an extra layer of moving weight: it is no longer just the emperor's grand plan, but also a response to a sacrifice of one's life.
