Yan Chunsheng learned crafts from Master Sun since he was a child, but he didn't know that his comfortable nest was actually a dragon's and tiger's den. Once the storm arises, there will be competition for territory and business. Even if you are as calm as a cloud, there will still be chaos. Yan Chunsheng is willing to be ordinary and only seeks stability, but in troubled times, there are many ups and downs. A good master, a senior brother, and the person you love with all your heart are all different. The world is rough and there is no escape from disaster.
