Serve XP without thinking HE. Yao Luheng, who had retired from the world for many years, was running the tea house left by his mother as usual. He had no enemies to worry about and his life was considered happy. On New Year's Eve, the mountain was covered with heavy snow, and her little devil-like niece sneaked down the mountain. Not only did she sneak away, she also picked up a life in the snow. The owner of the tea house was kind-hearted and took the person back to the tea house for treatment. As it turned out, that person turned out to be Liu Daxia's student He Pingyao. Liu Daxia died tragically six months ago, and the whole world was trying to steal her "Seven Hidden Sword Manual". I heard that only her students knew the whereabouts of the sword manual. It was better to throw this hot potato out as soon as possible. This person must not be kept, but...

I'll keep you safe." The man chose the latter and stayed in the tea house as a dog. The most vicious biting dog. Intention: live in harmony
