Siheyuan: Level Seven Engineer from the Start

After transmigrating into a courtyard home full of loyal martyrs, Ye Haoran became one of its residents. By his side was a younger sister, unrelated by blood, who had grown up with him and was as close as a real sister. While studying at Northwestern Polytechnical University, he learned that ill-intentioned people were eyeing his family home and daring to bully the childhood friend who had grown up alongside him. It was 1960, and although he had originally resolved to devote his youth to building the motherland, he applied for early graduation without hesitation, as a seventh-grade engineer.
