A Medical Student Travels Through Time and I Make Gunpowder at the Border

Clinical medical students travel through the fictional Song Dynasty and start the game on the refugee hell difficulty. Others relied on farming and doing business to survive in the imperial examinations. I relied on clearing wounds to save people and improving gunpowder to guard the border! Treat ulcers and wounds, build battlefield medical camps, adjust the optimal gunpowder ratio, and keep Di Yi thousands of miles away. No fantasy tricks, realistic growth, practicing medicine and guarding the border, and taking charge of the military and political power in northern Xinjiang.
