In the third year of Qingli in the Song Dynasty, there were internal and external troubles, constant party disputes, and Liao and Xia tigers looking from outside. The ghost of modern engineer Zhao Cheng'an passed through the life of a clerk in Bianjing and was sent to the south of the Yangtze River to control floods. He faced the dilemma of frequent embankment failures and the people's livelihood. At this time, he accidentally obtained the "Tiangong Kaiwu System". This system can unlock the technology of later generations, but it must rely on political performance, public support, and literati recognition to accumulate points, and unlocking black technology requires passing down articles to rectify the name. With the system, Zhao Chengan mastered the cement formula and water conservancy drawings, etc. He could create thunder, wooden cows and horses, and he could write policy papers with ease. While others were still worrying about traditional issues, he had gradually turned the Song Dynasty into a torrent of steel with its infrastructure. In the end, he will lead the Song Dynasty to achieve scientific and technological changes, move towards prosperity and power, and complete a civilizational leap.
