Chu Mo traveled through time to the Great Gan Dynasty and became a resident son-in-law of the military Ye family. Thinking he could lie flat and live off his wife, he suddenly found that all the men of the Ye family died in battle, leaving only a house full of widows and his wife Ye Qingwu struggling to support the family. Facing oppression from nobles and secret plots from foreign enemies, he no longer hid his talents. Relying on his peerless martial arts and extraordinary wisdom, he protected his family's safety, punished evil-doers, and resolved crises. He also entered the Brocade Guard, made great contributions, and step by step grew from a despised son-in-law into a pillar of the country holding world-shaking power and protecting the nation and its people.
