Lin Yan, a double master's degree student in the Department of Modern History + Department of Literature, accidentally traveled to the parallel ancient Yong Dynasty while staying up late to work on his thesis, and became a hungry boy in a small border village. His original parents were old, his younger siblings were still young, and his family had only half a dilapidated house left. With the knowledge of literature and history, political wisdom and modern thinking accumulated in two generations, Lin Yan started to solve the problem of food and clothing, improved farm tools, wrote documents, and gave lectures to gain a foothold, and met the smart and tough country girl Su Qingyi. He broke through all the way: he defeated evil gentry in the countryside, founded an industry in the county, won the imperial examination with his shocking strategies and won the gold medal, used his wisdom to resolve party disputes, implemented the New Deal, and quelled internal and external troubles in the court. Finally, he rose from a humble scholar to the pinnacle of power and became a famous prime minister who assisted in the prosperous age. During this period, he protected the health of his family, got to know Su Qingyi and stayed true to himself in the whirlpool of power and intrigue, and wrote a legend of "helping the world with literature and stabilizing the country with wisdom".
