My College Classmate Is Fusu, and Qin Shi Huang Is Thriving

My Emperor Zheng has come to the modern day. Aren't you going to come see him? A time-space passage has appeared between the Great Qin and the modern world. Fusu and his father, Ying Zheng, arrive at a modern university, where they meet Zhou Kai, an expert in the classical language of the Qin and Han dynasties. Zhou Kai thinks they're cosplayers and mistakes Fusu for a fellow university student! Qin Shi Huang: “Does my Great Qin still exist?” Zhou Kai: “Great Qin fell a long time ago. It collapsed more than two thousand years ago! And it only lasted two generations!” Qin Shi Huang: “What?! Fusu! You're so useless, Great Qin fell because of you!” Fusu: “Father, I...” Smack! Furious, Qin Shi Huang slaps Fusu across the face! He uses so much force that he falls over and passes out! He's still breathing. He hasn't kicked the bucket! Quick! Call an ambulance!
