Shocking! The Righteous Sect's Saint Actually Kissed the Sickly Demon Empress

System + female Demon Empress + yandere + cautious survival + cultivation + one heroine + daily life + decisive and ruthless Su Haoran transmigrated to a cultivation world and joined the Immortal Dao Sect. He always followed the Way of Keeping a Low Profile, never expecting the sect leader to appoint him as a holy son. When he failed to break through to the next realm, the System awakened. [Ding! Host, bind yourself to a woman within ten minutes. If you fail, the System will unbind, your cultivation will vanish, and you’ll be physically castrated.] Fortunately, there was still a way out. A woman in red fell from the sky. To his surprise, she was the Holy Maiden of Xuanyue Valley, a demonic faction, and in her previous life she was the famous Cangyue Demon Empress, Chu Lingxi... Chu Lingxi: “I... How should I repay you for saving my life?” Su Haoran: “How about you give yourself to me?” Chu Lingxi: “Husband~~~” What Su Haoran didn’t expect was that his wife would turn out to be a yandere who loved snuggling up to him and acting cute.
