Starting with ten elixirs of immortality, I led the First Emperor to rebel against the Qin Dynasty.

After traveling through ten years of the Qin Dynasty, I, Zhao Huan, finally welcomed back my father Zhao Zheng, who had been away from home for many years!
But my businessman father, no matter how you look at him, exudes an aura of imperial dominance.
"Father, after the First Emperor died, the people suffered terribly. Shall we two rebel?"
My father was silent for a moment, then said in a deep voice, "Agreed!"
So I offered potatoes, cement, and gunpowder to fully support my father.
Years later, I led my troops into Xianyang, intending to enthrone my father, only to find him already dressed in a dragon robe and sitting on the throne.
"Dad, your dragon robe cosplay is so realistic!"
The entire court of officials knelt down in unison: "Greetings, Your Majesty the First Emperor!"
I:"???"
