I Prayed to My Ancestors for a Match, and the Living City God Descended from Heaven as My Husband

[A naturally pure-boned sect leader and an unhinged heroine + a mission-bound male lead who is cold at first and a crybaby later + all kinds of metaphysical studies, math, physics, chemistry, and high technology] Others pray to their ancestors for safety. I pray to mine for a husband. All I ask is that he be handsome, rich, capable, reliable, and able to keep evil spirits in check! In the next instant, the dark clouds clear and a god appears before me. He is a living City God, wielding the brush of judgment over yin and yang, cold and merciless. Yet for me alone, he breaks his vows: “Your name is the only one in the Marriage Register. From this day forth, in heaven and on earth, I shall protect you.” From then on, ghosts and monsters give me a wide berth, and underworld officials bow when they see me. The world reveres the living City God, but the living City God dotes on me alone.
