The story takes place in the turbulent era of the Great Xia Empire. Lin Yuan, a boy from a poor family, was recruited to be the son-in-law of Su Qinghe, the daughter of a powerful man, because of his salvation. With a humble identity and low status, he suffered all the cold eyes and suppression. However, he relied on his intelligence and forbearance to stand out in multiple games such as the family, the world, and the temple. As he was involved in the Su family's internal strife, Jianghu turmoil, court intrigues, and national turmoil, Lin Yuan gradually grew into a mainstay that could change the fate of the ethnic group, gained true love and family ties, and finally achieved a double leap in identity and spirit, writing a legend from a humble son-in-law to a generation of heroes.
