During a border operation to capture drug traffickers, anti-narcotics police officer Qin Muyun was shot by one of them. When he opened his eyes again, he found himself in a strange world. After merging with the original owner’s memories, he learned that he had transmigrated into the household of Qin Wuming, Minister of War of the Great Xia Dynasty. He was the illegitimate son Qin Wuming had fathered with Jiang Ruyue, a maid in the household, while drunk. Afraid the truth would come out, Qin Wuming drove Jiang Ruyue out of the Qin residence. She died shortly after giving birth to Qin Muyun. Seeing that the newborn had no family, the villagers raised him until he was twelve. Later, Qin Wuming learned that Qin Muyun existed and, worried about the damage to his reputation, brought him back to the Qin residence. Qin Wuming’s principal wife, Su Zhilan, had two sons and a daughter: the eldest, Qin Mubai; the third son, Qin Mufeng; and the youngest, Qin Murong. Afraid Qin Muyun would compete with her children for the family fortune, Su Zhilan and her children began beating and cursing him as soon as he arrived, wishing he would die. But after Qin Muyun transmigrated, he punched the Qin women and kicked the stubborn young masters, soon making a name for himself throughout Great Xia.
