Twins Turn the Tide

As children, Zhang Qishan and his identical twin brother, Zhang Xiaofeng, were separated after a bus accident. Years later, Zhang Qishan became the war god of the southern region and has been searching for his brother. Meanwhile, Zhang Xiaofeng was adopted by the Su family, entered the family as a groom, and became a stoic wealthy man's son-in-law. At the Su mansion, Zhang Xiaofeng endured humiliation and exploitation from his mother-in-law, Li Xiaofen, his brother-in-law, Su Hai, and his wife, Su Yuebai. He developed software to support the Su Group but had his achievements appropriated. He suffered from heart disease (later confirmed as a misdiagnosis) but had his medication hidden, and he was beaten, scolded, and forced to work for free. Su Yuebai also entangled herself with the powerful Qi Yan, showing no concern for his illness.
