The wealthy state of Fuzhou, adjacent to the bustling metropolis of Shanghai, is a prosperous area on the Hangjiahu Plain that has produced many great merchants. The competitive and ostentatious风气of the wealthy families escalated over time. Xuan Yongzhuo, having just inherited a vast family fortune, took unconventional and bold moves, even more so to reverse a passive situation. He called off his engagement with the Wan family and instead married Rong Shasha, the daughter of a Shanghai silk tycoon. With his intelligence and courage, he quickly defeated Wan Hai, who had been in competition with the Xuan family for many years, becoming the richest man.
The Anti-Japanese War began, and the economic aggression of the Japanese was devious and rampant. Under the guidance of underground party members, the struggle between Xuan Yongzhuo and Yoshida Takahito, a Japanese economic special agent, evolved from being covert to overt, with perilous twists and turns. The infiltration by the Military Intelligence Bureau, the betrayal of local garrison troops, the cunning and dishonesty of the Nationalist mayor repeatedly placed Xuan Yongzhuo in dangerous situations. Wan Fu became the security captain of the Fuzhou branch of the Wang puppet regime, while Wan Hai served as the president of the Sino-Japanese United Chamber of Commerce. The Xuan family's silk factory, Daming Power Plant, and Chengxin Money House, which he had long coveted, fell into his hands one after another. Wan Jia's young lady, Yaxin, who was forced to stand against Xuan Yongzhuo, suffered the pain of being abandoned due to a broken engagement. After much hardship and twists, she finally married her beloved. Zhou Lingjuan, a famous actress of Yue Opera, although charming, possessed a strong sense of pride. For her confidant, she remarried Long Wu, the chief of the漕帮with a rough and vulgar demeanor.
