In the early years of Zhenguan, two mysterious diners appeared on the streets of Chang'an. They chatted about government affairs and inquired about the general trend of the world every day. Lin Shu, a cook in the market, only thought that they were wealthy businessmen, casually predicting natural disasters, breaking down the war situation, and asserting that the Turks would be in chaos. Every sentence came true and every word touched his heart. It wasn't until something happened in the court that Lin Shu suddenly realized that the acquaintance he chatted with every day was actually the emperor Li Shimin.
