Da Qin: My Father-In-Law Is the First Emperor? !

Zhao Chen decided to get married in order to avoid corvee labor in the thirty-sixth year of Qin Shi Huang's reign. However, my sister brought an old man home and said he was his father-in-law. When he used acupuncture to relieve the old man's severe pain, exposed the fatal dangers of taking pills, and even used farming techniques to demonstrate an astonishing grain yield, he found that the old man's eyes were getting worse and worse. Until one day, Zhao Chen was confused. What I saved was not my future father-in-law, but Qin Shihuang? !
