Shen Tieshan, a railway engineer who returned from studying abroad, was full of passion and wanted to awaken the sleeping China with an iron dragon. Unexpectedly, he was framed by the conservatives for "colluding with foreigners and destroying the dragon's veins" as soon as he set foot on his homeland, and he was almost executed! Thanks to the protection of enlightened officials, he was sent to the most dangerous Nanling Mountains, where he was ordered to build a "heavenly road" connecting the north and the south. However, this is not a grace, but a desperate situation: the mountains are dangerous, the geology is complex, foreign powers are eyeing it, and the technological blockade is like an iron wall. What's even more terrible is that his mentor turned out to be the core of the conservatives, obstructing the project overtly and covertly; the exposure of mineral deposits along the railway line attracted the covetous powers, who wanted to use the railway to plunder resources; there was even a secret organization lurking among the workers, trying to use the railway project to launch an anti-Qing uprising!
Faced with internal and external troubles, Shen Tieshan relied on his extraordinary engineering wisdom to carve a way out of the cliff. He used ingenious tricks to resolve the superstition of Feng Shui and win the hearts of the people; he used the weak to defeat the strong, broke through the technical barriers of the great powers, and invented the "Shen's Rail"; he dealt with all forces, not only to preserve the project, but also to protect the minerals, and to be alert to the hidden undercurrents. When the last rail was laid and the dragon roared past, Shen Tieshan not only built the railway, but also awakened the industrial soul of a nation! And he also went from a "sinner" sentenced to death to the "Father of Railways" who shocked the world!
