Lin Mo, who holds a Ph. D. In mechanical engineering and materials science, was suddenly struck by a thunderstorm while debugging a nuclear fusion reactor. His soul was transported to a mass grave in Chang'an in the third year of Zhenguan. He was seriously injured and became a refugee. With half a wooden sign saying "The Ministry of Works will supervise", he repaired a broken grain truck using the tripod principle and was recommended by the school captain to join the Ministry of Works.
Faced with the heavy problem of the straight-column plow, Lin Mo improved the curved-column plow in three days and nights. One person and one oxen plowed three acres per day. Cui Jiulang, the general's junior eunuch, recommended it to Duan Lun, the minister of the Ministry of Industry. Later, a keel waterwheel was built to solve the irrigation difficulties in Guanzhong. Although the chain jammed during the demonstration, it was still appreciated by Li Shimin. He was awarded the title of Seventh Grade Superintendent and served as a young prisoner, and more than 200 waterwheels were built.
He also conquered the technology of coal and iron-making, lining the furnace with clay to reduce the impact of sulfur. In the fourth year of Zhenguan, when the Turks invaded, Lin Mo searched for saltpeter, purified gunpowder and made thunderbolts. In ten days, he built thousands of thunderbolts and hundreds of cannons, helping the Tang army defeat the Turks and capture Jieli Khan.
After the war, Lin Mo developed a steam engine to solve the problems of boiler sealing and cylinder accuracy, which led to the advent of automatic looms and steam hammers, and cloth production surged. Li Shimin established the "Technology Department" and appointed him as the director. Lin Mo overcame resistance and opened a science and technology school to teach mathematics, physics and mechanics to poor children, laying the foundation for the rise of science and technology in the prosperous Tang Dynasty, and determined to push the dynasty into a more high-tech era.
