Five years after Xu Yechen was imprisoned, he returned home to look for his father, only to discover that Xu Zhiheng had married into the wealthy Lin family. Xu Yechen unexpectedly gained five sisters, including Lin Ruoxing and Lin Anhe. Barely back home, he was caught up in a debt dispute left behind by his father and set up by the creditor Luo Zhiyong, but he used his own abilities to resolve it with ease. After joining the Lin family, he gradually became part of his new household. Though he initially clashed with his spoiled younger sister Lin Yitang, they grew close through one incident after another.
To investigate the disappearance of students at Juying Academy and protect his sisters, who attend the school, Xu Yechen entered through a special recruitment program. There, he met the campus belle Shen Bihan and got caught up in school turmoil. He also faced provocations and plots from the Fu and Ruan families, among others. These factions had deep ties to the underground Black Wind Hall, the Eastern Japanese Phantom organization, and the Qi family, and their schemes even led to a major incident involving an assassination attempt on the Emperor.
With his concealed strength, the secret power of the Hall of Yama, and the support of the Lin sisters, Xu Yechen repeatedly survives crises involving business bids, campus clashes, and assassin attacks. While secretly investigating the missing students and the conspiracies of the various factions, he finds the warmth of family in his new home and contends with tangled romantic relationships. He moves ever closer to the truth, preparing for a final showdown with the mastermind behind it all.
