Formerly the number one Sword Venerable in the world who dominated the Nine Provinces and suppressed ten thousand enemies with a single sword, Chu Wuchen grew tired of the conflicts and killings in the cultivation world. He sealed away his heaven-defying cultivation and transformed into an ordinary, leisurely scholar in the mortal world to experience human life. By a stroke of fate, he was recruited as a matrilocal son-in-law by Pei Jinyue, a down-and-out young lady in Yunzhou whose spiritual power was completely destroyed, using a single ingot of gold. As the two spent time together, layers of secrets regarding their identities were unraveled, and past gratitude intertwined with present feelings to spread and grow. Pei Jinyue held the authority of the chamber of commerce and dominated the business world, while Chu Wuchen relied on his supreme swordsman Dao to protect her safety. One wielded wealth and the other suppressed the world; this couple full of contrasts, starting from the old Pei residence, stirred up the winds and clouds of the entire cultivation world. Let us watch the strongest Sword Venerable willingly become a matrilocal son-in-law.
