Feng Qiwu, the daughter of the chief bodyguard who was born in a bodyguard bureau and possesses extraordinary martial prowess, married into the Liu Mansion, one of the top aristocratic families in the capital, for the benefit of the family. She originally wanted to live a stable life, but found that her husband's backyard was the most dangerous place. The yandere and scheming husband, the scheming concubine, the arrogant and domineering servant... None of them are economical. Feng Qiwu had to pick up his skills, rectify the backyard with modern management thinking, and train a group of jealous men into his right-hand men. Unexpectedly, he discovered that there was a shocking conspiracy behind them that could subvert the imperial power. The highlight is that the heroine is not reborn through time travel, but relies on her own hard power and clear mind to carve out a path of power in the "Male Version of the Legend of Zhen Huan", and with the sinister husband who seems weak but is actually the strongest supporter, she goes from contract marriage to soul mate.
