Lin Qian came to Jiangcheng with the marriage letter left by her grandfather and signed a couple agreement with Lu Zhishuang, the female president of Bingshan. He thought he was just helping her deal with the pressure to get married, but unexpectedly, the "kissing his wife will make him stronger system" was activated: as long as he kissed Lu Zhishuang, he could increase his cultivation and unlock skills. During the day, he is Lu Zhishuang's obedient and docile contractual boyfriend; facing the cultivation sects, underground forces and secret services hidden in the city, he is calm and decisive, breaking through the situation step by step. What is even more surprising is that Lu Zhishuang possesses a rare high-grade ice spirit root, and the "Taixu Jue" practiced by Lin Qian also revealed a secret that had been sealed for twenty years. From contracted lovers to true love, the two cultivated and became stronger while facing the constant crises in the darkness of Jiangcheng. He was a feared strong man outside, but in front of her, he was always a little puppy who only wanted to be kissed.
