After I Became Huhai, Qin Shi Huang Could Hear My Thoughts

Question: What would you do if you transmigrated to the Qin Dynasty? Answer: Kill Hu Hai first, then Zhao Gao. Ask His Majesty the First Emperor to live another thirty years, and finally tell him all the scientific knowledge I can remember. After typing that answer, Hu Hai, a freshman history major, transmigrated into Hu Hai. Yes, that Hu Hai: Qin Er Shi, who left countless jokes for posterity, wiped out his own clan, and brought the Great Qin Dynasty to ruin :) Hu Hai: "…" Great, step one: kill Hu Hai, done! Ever since his youngest son Hu Hai recovered from an illness, the First Emperor discovered that he could hear the boy's inner thoughts. [Zhao Gao, you altered the imperial edict, called a deer a horse, and tried to usurp the throne. How dare you keep running your mouth in front of me? Get lost! Get lost right now!] Qin Shi Huang Zheng: "?" [Fusu, Fusu, why are you stubbornly arguing with the First Emperor? Keep this up and His Majesty really will send you to the frontier to oversee the troops!] Qin Shi Huang Zheng: "??" [That bastard Xu Fu swindled His Majesty out of his trust and his money, then just turned around and ran off. Trash! Absolute trash!] Qin Shi Huang Zheng: "???" [Was the Qin Dynasty the smallest of all the dynasties? Just one-third the size of China in later generations, and less than one four-hundredth of the world's land area?] Qin Shi Huang Zheng: "!!!" Many years later, the Great Qin grew ever more powerful. Savoring freshly delivered grapes, watching fireworks bloom in the sky, and looking back at the sight of all nations paying tribute... Hu Hai cupped his face in bewilderment. "I didn't even do anything. How did Zhao Gao die? Where did Xu Fu go? How was the Silk Road opened? And how was the New World discovered?" Hu Hai fretted, then gave up. Hu Hai was in a wonderful mood and decided to eat another piece of fried chicken! Just then, Prince Gao hurried in. "Brother Hu! Brother Hu! I heard Father has issued an edict naming the Crown Prince. Guess who it is?" Hu Hai took a big bite. "Big Brother Fusu?" Prince Gao shook his head. "It's you!" Hu Hai: "…Pfft!" The First Emperor, hearing Hu Hai's furious inner voice for the first time in ages, heard him shout: [Your Majesty, you've lost your mind!!!] A few things to know before reading: 1. An alternate ancient setting and parallel world, an extremely satisfying power fantasy, with a golden finger and plenty of authorial inventions!!! 2.
