I Cheated with My Knowledge in Siheyuan

Time traveled to become the nephew of a courtyard man, or graduated with a major in mechanics? Yi Baoquan looked in the mirror at the skin of an educated man and the core of his own scumbag, and panicked. Fortunately, the time-travel benefits arrived on time - [Item Analysis and Improvement System], it is powerful, but what are the shortcomings... You need to study! As a result, everyone in the courtyard discovered that the new boy from the Yi family was stunned! In the workshop, he never let go of "Mechanical Principles"; at the dinner table, he read "Fundamentals of Mechanics" while eating; even when he went to the toilet, he carried a copy of "Soviet Industrial Standards Collection"! Xu Damao: "Pretend! Just pretend!" Silly Zhu: "This knowledge doesn't enter the brain!" Qin Huairu: "Baoquan, do you think this sewing machine... Can be improved?" Until one day, he improved the machine tool from Da Maozi and shocked the whole factory. Yi Baoquan smiled slightly: "I've told you, knowledge is power." (System prompt: The energy is full and the target can be resolved: the first domestic CNC machine tool?)
