While other time travelers were busy opening golden fingers, Fang Jun improved siege equipment with pulleys, shocked Li Shimin with sand table deductions, and used ecological knowledge to control the locust plague. Zhenguan furnace, Datang Academy of Sciences, joint-stock caravans, Chang'an sewer system... All these "inventions" made Tang Taizong call him "this son is a monster", and made Fang Xuanling wonder every day whether his son had been struck by lightning and was stunned.
In the court, he almost extended KPI assessment to the prince's education; in love, he used a SWOT analysis chart to reject Princess Gaoyang's pursuit; even when he invented a menstrual towel, he was beaten with a stick as if he were a prostitute. The collision of ancient and modern cultures makes the serious Zhenguan era full of nonsense - "666" is regarded as a curse, the PPT report thinking makes the officials confused, and the Datang version of "shared bicycles" (horse rental) detonates the city of Chang'an.
But when the butterfly effect caused a storm, the wealthy family regarded him as a heretic, the whirlpool of inheritance surged, and even another group of time-travelers emerged - Fang Jun discovered that it is easy to change history, but it is difficult to control the changed history.
