On the eve of the fall of the old capital 87 years ago, a "real-time life signal" suddenly jumped on the screen - signal source: Dark Age, name: Ye Zhan, occupation: unemployed coder. No one told him how to go back, only gave him an iron rule: while alive, he can use his mind to drag future weapons into the rift of time and space. The first bullet was twisted into iron filings by him, and the first black-armored army was blasted into blood mist by the unknown cavalry. History began to "entropy crack". Every time a life was saved, a city would be randomly wiped out in the future. The top brass roared: Is he the key to saving the country or the trigger to destroy the world? Ye Zhan sneered: I am just a mortal, but I want to sacrifice my enemies to heaven and light my cigarettes with my fate! Open this book and see how an ordinary person rewrites the fate of the country with his breath and tears apart time with his anger!
