Siheyuan: Start by Brushing up Proficiency

"Lin Yi crossed the courtyard and became a resident of the courtyard, and became Jia Dongxu's coworker." The old man originally wanted to develop Lin Yi into his retirement partner, but he didn't expect that this kid wouldn't listen to him. So I never taught Lin Yi my skills, but I never thought that Lin Yi himself had a proficiency system. As long as he repeats the work, he can gain proficiency, and enough proficiency can improve his skills. After a few years, the first man will deeply regret his stupidity.
