Shen Mo, a PhD student in 985 Engineering, woke up and found himself lying in a dilapidated courtyard in Bianjing in the Northern Song Dynasty - his father was demoted, his family was in ruins, his creditors blocked the door, and he was thrown from the Fan Tower and suffered a concussion.
Just when he thought this was the beginning of hell, a system called "Tiangong Kaiwu" was activated in his mind.
Cement, repeating crossbows, gunpowder optimization, blast furnace steel smelting, steam engines - these things that should not appear for thousands of years were moved one by one into the Northern Song Dynasty during the Xining period. He used the assembly line to transform the ordnance supervisor, used cement to repair a city wall in three days, and used firecrackers to defeat the Liao cavalry on the battlefield.
Wang Anshi regarded him as the trump card of the reform, Sima Guang regarded him as a monster, the people of Liao Dynasty called him "ghost work", and the people of Bianjing called him "magic work".
From a down-and-out yamen with a debt of 130 yuan to the minister of the Ministry of Industry who took charge of Tiangong Society and changed an era - Shen Mo just wanted to prove one thing: given enough time to an engineering student, he could make history turn a corner.
And the general and supervisor's daughter Su Nianqing who helped him research ink, calculate data, and draw drawings was probably the second most cost-effective thing he did after time travel.
