Zhao Kuo accidentally traveled through time and became the Barbarian King Meng Huo. He changed the structure of Nanzhong, helped Prime Minister Zhuge pacify Nanzhong, improved productivity, and then assisted Prime Minister Zhuge in his Northern Expedition. The Sima family never had the chance to create the Jin Dynasty.

Cao Rui: Is this true or false?
Zhuge Liang: Sima Yi usurped the throne?
Meng Huo: You have no chance! The emperor of the Han Dynasty was named Liu! The prime minister of the Han Dynasty was named Zhuge!
