Zhao Tuo died. When he opened his eyes, he found himself in the Warring States period with all his memories intact, as the grandson of the Crown Prince Dao of Qin and cousin to the First Emperor of Qin.
From birth, he suffered from a soul-separation disorder. His disembodied soul floated beside the newborn Ying Zheng.
After Qin's defeat at Changping, Qin forces surrounded Handan, and Ying Zheng and his mother suffered repeated humiliations at the hands of the people of Zhao, living in desperate circumstances.
Watching little Ying Zheng teeter on the brink of death under the abuse of the people of Zhao, Zhao Tuo's overwhelming fury drove his soul into Ying Zheng's body.
From childhood, Ying Zheng knew he was different from other people. There was someone beside him whom nobody else could see.
When his father abandoned him and his mother, and the people around them wanted nothing more than to kill him, the person who had always stayed by his side descended like a divine soldier and used Ying Zheng's body to fight back against everyone who bullied him.
Little Ying Zheng: "Are you an immortal from heaven?"
A young voice replied, "I'm no immortal. I'm your big brother."
Zhao Tuo discovered that whenever he possessed A Zheng, part of A Zheng's soul would also enter his own body.
Little Ying Zheng always thought his big brother was an all-powerful immortal. But the first time he possessed his big brother, the voiceless throat, the limbs he could barely control, and the mockery and pity hidden in the shadows all displeased him.
His big brother was so good. His life shouldn't be like this.
As the two of them kept switching places, Zhao Tuo's soul-separation disorder slowly began to improve.
But as his condition got better, Zhao Tuo realized that they could no longer switch unless one of them was in a state of extreme emotional distress.
After that, Zhao Tuo used his great-grandfather's favor to bring Ying Zheng back to Qin ahead of schedule, doing everything in his power to help him claim the throne, contend with powerful ministers, and unify the six states...
Whatever A Zheng wanted, A Zheng would get.
Premise: Never give up. There will always be a turn in your fate.
