In Siheyuan, I Just Want to Get Away from the Birds

[Siheyuan fan + single female protagonist + slight violence + romance + time travel + system + strong country + non-cao thief + will slowly leave Siheyuan in the later stage] Chen Kuangyi traveled through time and entered the world of the legendary "Siheyuan", but he is different from most time-traveling male protagonists. He has both parents and a beautiful and smart sister. After graduating from college, he became an engineer and has a bright future. The system he is bound to is also very positive. It's called the "Qiangguo" system, and you may be unable to avoid the protagonists of the courtyard if you really travel into the courtyard. The house allocated by the steel rolling mill is No. 95 Nanluogu Lane, which is the boundary of the birds. The appearance of Chen Kuangyi broke the tranquility of the courtyard. The young wives all cherished his love for him. The male People were envious, jealous, and hateful of him, so that Chen Kuangyi was often targeted. Chen Kuangyi was stupid, but he knew how to impress people. He had a father who was the chief of the security department and a mother who was from the subdistrict office. As soon as they appeared on the scene, they left the scene in embarrassment without opening their mouths. In addition to watching the drama of the birds every day, Chen Kuangyi also met the love of his life, and after getting married, he began to do his best to help the country. Looking at blast furnaces, cars, electrical appliances, rockets, and satellites that appeared earlier than in history, Chen Kuangyi closed his eyes with joy and shed his last patriotic tears.
