Zhou Qi, a modern ordinary person, traveled to ancient times and became a poor scholar with a poor family. He unexpectedly married Su Ling, a rich girl who pretended to be mute. With modern knowledge, he counterattacked the business world by inventing toothbrushes, purifying refined salt, and improving textile machines. During this period, he met Liu Sichen, the son of the county magistrate, and military general Han Dutong, and was involved in the secret struggle between the imperial power and the prime minister. At the same time, he developed bonds with women such as Wu Zhitao and Qing Leng, and finally established a foothold in ancient times and achieved both career and family success.
