Mechanical engineer Qin Mo accidentally traveled to the Jiajing period of the Ming Dynasty and became a ninth-rank junior official in the Ministry of War. When he discovered that the Ming Dynasty in this time and space was more precarious than recorded in history—Japanese pirates were raging, borders were in crisis, and the court was corrupt, and when he actually traveled through it with an entire modern machinery workshop, he decided to use modern technology to rewrite history. From improving muskets to making flintlock muskets, from forming a new army to fighting against treacherous officials in the DPRK, while Qin Mo changed the course of history, he also gradually revealed the shocking secret behind his own time travel - this was actually a civilization saving plan that spanned five hundred years.
