Modern engineer Zhang Wan was struck into the ancient Song Dynasty by a strange lightning. In the cold night when the temple was broken down, he lit up a bonfire and hope with only a backpack full of modern tools.
When the Bian River was frozen and water transportation was cut off, he built ice-breaking rafts to relieve the plight of the people; locust plagues ravaged fertile fields, and he used the method of light trapping to protect a granary; when farming was backward and there was famine, he improved waterwheels and promoted high-yielding rice seeds, allowing wild gold to be everywhere; when powerful enemies invaded the border and disturbed the border, he cast cannons and muskets, and built iron walls of defense.
From a small workshop in the countryside to the chief engineer in charge of the royal workshop, he used modern knowledge as an edge to break through the shackles of the times. Building water conservancy, opening sea roads, printing banknotes, and setting up schools gradually pushed the Song Dynasty to the peak of prosperity.
This is an adventure of traveling alone, and it is also a legend of a mortal using his wisdom to navigate the world and benefit all people. When the spark from another world illuminates the Millennium Song Dynasty, let's see how Zhang Wan uses the star as a boat to cut through the waves in the long river of history and write his own glorious chapter.
