Li Qingmu is a dirt-poor scholar from the Lower Realm who was raised by parents who literally starved to feed him so he could study. After they died from overwork, he swore he would honor their sacrifice by making it into the Imperial Academy.
    He succeeded barely.
    Because he was poor, the immortal-born nobles looked down on him.
    Except one girl: Zhen Rou, the fat, ugly, arrogant daughter of a high-ranking Immortal Official. She liked him because he was “obedient” “harmless” and “would never dare refuse her.”
    She forced him into marriage.
    On their wedding night, when he was praying for death, he heard a voice:
    [Family Development System Activated. Starting Lineage Upgrade Program.]
    From that moment on:
    Every improvement in his wife’s beauty, strength, destiny, or bloodline = boosts to his cultivation.
    Every child he births = a massive cultivation blessing based on the child’s innate talent.
    Every family expansion = new system features.
    His entire cultivation path is tied to building the strongest immortal clan in the heavens.
    He begins as a powerless son-in-law despised by his in-laws and rises to become a Heavenly Official whose influence shakes the Upper Realms!
