Qin Chen traveled back in time to the third year of Zhenguan and became the "idiotic" nephew of Duke Yi Guo Qin Qiong.
He originally wanted to be a playboy waiting to die, but he didn't know that his uncle was critically ill. He had no choice but to use his medical skills from his previous life, perform a cesarean section, remove stones, and save his uncle's life.
After saving people, Qin Chen wanted to continue enjoying his life: brew some liquor to drink, make soap to wash with, and make some ice cubes to cool down.
But Li Shimin quit: "Qin Chen! If you have this ability, why can't you do something serious?!"
Qin Chen looked innocent: "Your Majesty, I am very serious. I enjoy the blessings and the court collects taxes. It's the best of both worlds."
All the civil and military officials of the dynasty: This traitor is bringing trouble to the dynasty!
Qin Chen: I really am not, I just want to enjoy happiness!
