If Teaching Fails, Then I Will Use Force to Create a New Dynasty

Li Jing originally had a heart to serve the country, but the road to the imperial examination was bumpy. He was imprisoned because of a policy paper that offended the powerful officials of the dynasty. After being released from prison, he was disheartened, so he returned to his hometown and became a teacher... But Dachong, which has been a country for 300 years, has already shown signs of the twilight years of its dynasty. The foreign tribes outside the customs are dissatisfied with the king's rule and repeatedly knock on the pass, the border troops are lax in their armaments, the party disputes in the court are constant, the emperor is suspicious, and there are constant natural disasters in the country! Externally, the country is in turmoil, and internally the people are displaced, exchanging children for food! In a world of purgatory, Li Jing had no choice but to embark on a road to establish a new dynasty by chance!
