Eighteen hundred years ago, the Xixia cliffs isolated a region of people. A modern geotechnical engineer accidentally time-traveled back to the Eastern Han dynasty, becoming Gongcao Li Min, who witnessed multiple road-construction tragedies. The court engaged in fierce debates, the people turned pale at the mention of roads, mountain torrents raged, and a hundred-zhang precipice blocked the way forward. Breaking the inherent thinking of the ancients, he used engineering wisdom to fight against natural perils, cooperated with Prefect Li, united the people of the Han, Qiang, and Di ethnic groups, and opened up the ancient Xixia road with blood and sweat. Qiu Jing wielded his brush to write the epitaph, engraving the perseverance of a generation onto the cliff stone tablet of the "Ode to Xixia", leaving it to future generations a thousand years later.
