Born into the Qin Dynasty, I faced an assassination attempt before I was even born. I cut my way out of the womb, and purple qi swept in from the east as every dynasty came to pay homage! Donghuang Taiyi submitted to me, Guiguzi fought to take me as his disciple, and the Ancestral Dragon saw me as the fortune of the nation. They all thought they were raising a sage, but I only wanted to be a carefree rascal. Then one day, I pointed at a map of the Six States and said, “Father, this territory is too small.” Only then did the world learn that a sage’s wrath leaves a million corpses in its wake!
