Meng Xingruo, who had stayed up all night to catch up on the drawings, died suddenly, and when she opened her eyes again, she became the useless third lady who was hated by the people of the Meng family. Only the crazy aunt hugged her and cried: "My son is not a monster! He is a star that fell when the sky cracked!" Meng Xingruo looked at the leaky courtyard and smiled: Is this unprofessional? She improved the rammed earth, fired cement, and transformed the courtyard into a beautiful building that shocked the whole government. Heavy rains destroyed the Meng Mansion Ancestral Temple, and she spent the night drawing a diagram of how to repair the brackets: "The mortise and tenon joints are loose, so we need to use triangles to support them."
When the enemy's cavalry broke through the border, Meng Xingruo stood at the top of the city and chuckled: "The moat is too narrow? Look at my hydrodynamics and flood seven of his armies!" At the new emperor's coronation ceremony, she stroked the homemade concrete relief on the throne: "I am a professional in infrastructure construction." It wasn't until the coronation night that she opened the drawings left by the crazy aunt, and there were drawings of modern excavators and steel structures on them.
