Xie Ming, a national first-class cultural relic restorer, died trying to save an ancient painting in a museum fire. When he opened his eyes again, he found that he had traveled to a different world where steam machinery and mysterious runes coexisted - the Rhine Empire. There is no gorgeous magic in this world, only steam cores, mechanical prosthetics and rune technology. The object of his possession is Duke, a loser student at the Empire's Tenth Knight Academy. Due to his ruined family background and damaged core, he is about to be expelled.
While cleaning up the dilapidated dormitory, Xie Ming recognized the lines of the ancient painting he had saved in his previous life from a roll of parchment that was treated as waste paper. The moment he reached out to touch it, countless memory fragments exploded in his mind: that was actually the memory of his previous life as a "Rune Mechanic"! It turns out that he did not travel through time, but was "resurrected" - this world is the place where he fell in his previous life.
Faced with the danger of exposing his abnormal identity, Xie Ming must use turtle-like forbearance and patience to hide his sudden surge in rune knowledge and mechanical talent. There are many factions in the academy, the imperial military is monitoring him, and enemies from his past life are secretly spying on him... He works step by step, repairing the core of the machine, deciphering the ancient runes, and in the dangerous steam city, he gradually uncovers the truth about his death in his previous life, as well as the shocking secret hidden in the scroll that can subvert the empire.
