I, Li Er: Drafted the Draft on the First Day of the New Dynasty

Travel through time and become Li Shimin, the emperor of the ages. You should make great achievements. However, this host is a senior otaku. My only hobby is drinking Happy Fat House water and playing League of Legends. But now. There are no video games, no Internet, and no nerds. There was no running water, not even toothpaste. There are just mountains of memorials, scheming ministers, the ambitious Qiwang of the Five Surnames, and the Turkic bandits who are eyeing them. So, He resigned on his first day in office. But. However, the civil and military officials of the Manchu Dynasty rejected him. No way. If I'm not allowed to resign, can I do the draft? One emperor through the ages? I don't want to do it. But my strength doesn't allow it! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
