Liu Chen, 28 years old, is a top architectural designer and an archeology enthusiast. During a restoration project for the Tang Dynasty ruins of the Forbidden City, he accidentally triggered a rift in time and space. When he woke up, it was the winter of the fourth year of Dasheng Dynasty and a dying refugee outside Chang'an City. When he was hungry and cold, he bound to the [Tiangong Kaiwu·Renovation System] - which can analyze the structure of all things, repair any item without damage, and even exchange for advanced technical drawings.
In order to survive, Liu Chen relied on the system to repair the guqin, and was taken in by the shopkeeper of "Muqi Zhang" in the West City. From then on, he entered the world of craftsmen in the Dasheng Dynasty. From restoring an ancient object to improving farm tools, building palaces, and designing new coins, he gradually grew from a humble apprentice to a powerful "master of heavenly craftsmanship." However, every "renovation" touched the interests of the old nobles, undercurrents surged in the court, and the whirlpool of power involved him in a deeper crisis. He not only wanted to restore the artifacts, but also "renovate" this solidified era - break the abasement system, set up technical schools, and reform the official system. When the emperor is seriously ill and the princes seize the throne, how will Liu Chen choose? Should he continue to assist Mingjun, or should he retire after his success?
This is a legend in which time-travelers use technology and wisdom to reshape the destiny of a dynasty. It includes fireworks in the market, turmoil in the temple, and profound thinking on "observing things to gain knowledge."
