In the spring of the 24th year of the Republic of China, Yan Shuhong, the richest man in Nanxun, was poisoned on the night of his fiftieth birthday. Yan Zhengqing, the eldest son who had left home and lived alone, received his father's legacy - the Haohan Hall Library as his father was dying. Subsequently, a golden tablet passed down through the Yan family sparked a fierce battle among the three wives for its possession. But at this time, the master miraculously came back to life.
In fact, the master didn't really die; he was just poisoned by a toxin called "Soul Returning Powder", which was administered by his fourth concubine, Shan Qing. Who would have thought that Shan Qing, the fourth concubine who had accompanied the master for eight years, was actually a descendant of the Wei family, which bore a deep grudge against the Yan family?
