Modern-day king of soldiers Lin Feng transmigrates into the Yan Dynasty, only to find himself in a miserable situation from the start: his biological father, Lin Hong, is cold and heartless, his birth mother died in grief, and his concubine stepmother, Madam Liu, stole fifty thousand taels of her dowry. Lin Feng, the “legitimate son,” and his younger sister Lin Shuang are demoted to servants and subjected to endless abuse. Worst of all, Madam Liu's son, Lin Yaozu, wants to steal Lin Feng's imperial marriage decree, which betroths him to the talented Su Wanqing!
Cornered, Lin Feng fights back. To save his sickly sister, he sells poems on the street. His stirring martial spirit draws the attention of Emperor Yanwu, who is traveling incognito, and Lin Feng earns a generous reward by presenting a poem before the emperor! On the way home, however, he accidentally knocks out Princess Changle, who has sneaked out of the palace and suffers from tuberculosis. In a desperate moment, Lin Feng uses modern CPR to pull her back from the brink of death, but the princess decides he has “ruined her honor.”
With his initial capital secured, Lin Feng and his sister escape the wolf's den and reclaim part of their inheritance: a nearly bankrupt restaurant that Madam Liu “gives” them. He applies modern business methods and makes it thrive, right across the street from a business owned by the princess! As they clash in the business world, the proud Princess Li Yun is drawn to Lin Feng's talent and air of mystery, and feelings begin to stir.
When the princess's old illness brings her to the brink of death and the imperial physicians are helpless, Lin Feng risks his life to bring out penicillin, a “secret medicine from his master's sect.” At the critical moment, the princess confesses her love through tears. The medicine works like a miracle. Lin Feng achieves yet another feat and wins both the emperor's favor and the princess's heart. Emperor Yanwu forcefully arranges their marriage, while Su Wanqing regrets everything.
Under Lin Feng's leadership, the Yan Dynasty's national strength soars. Its iron-blooded armies crush their powerful enemies and sweep across the Six Directions and Eight Wastelands, until it becomes the greatest empire in the world! Yet despite his unparalleled achievements, Lin Feng keeps his accomplishments hidden and retires to a peaceful village. The emperor who brought about the Yan Dynasty's golden age abdicates in favor of becoming Retired Emperor, following Lin Feng into the mountains to fish and watch the world unfold, leaving the new emperor looking on with envy.
