The time traveler Li Yan became the "dog-licking prince" of Xia Kingdom. The original owner was obsessed with Wei Yun, the princess of Wei Kingdom, and betrayed the country in pursuit of glory. After Li Yan woke up, he slapped Wei Yun in the face, and joined forces with Princess Ji Qingyan of Jin to subdue the demoted general Han Shizhong and take control of the military. Faced with the stupid and licking father, the vicious queen, and the conspiracy of the Wei State, Li Yan decisively rebelled and seized power, becoming emperor. He developed the economy, reorganized the army, purged traitorous civil servants internally, and used tactics externally to trigger internal strife in Wei. In the final decisive battle in the capital, he used an empty city strategy to lure the enemy, cooperated internally and externally to annihilate 300,000 Wei troops, counterattacked and destroyed Wei, succeeded to the Jin state, unified the world, created a prosperous age, married Ji Qingyan as his queen, and conquered Wei Yun.
