War of Resistance: I Start with Steelmaking and Shock the World

Li Zhen transmigrates back to that humiliating year of 1938. Everyone else who transmigrates gets to lead troops into battle, but what can a heavy-industry engineer do? The answer: make steel! While everyone else is still using low-quality pig iron, he uses coke made by primitive methods to produce the first gleaming steel ingots! While the army is struggling to scrape together a few bullets, his arsenal has already achieved a steady supply of ammunition and even begun researching Katyusha rockets!

It is a nightmare we can never defeat!”
