The Great Craftsman of the Siheyuan

Traveling to the courtyard world, he became Jia Dongxu who was about to get married. In the future, he has to support his wife, children, and mother, so the monthly salary of twenty-seven and five yuan for a first-level fitter is a little tight. Fortunately, in the Awakening of the Great Craftsman system, if the salary is not enough, the monthly salary of eighty-five yuan for an eighth-level fitter should be enough.
