The Empire Rises, and the Great Powers Turn Out to Be Me

Special forces king Chen Feng transmigrates to another world and gets a Daily Sign-In System, which gives him all kinds of supplies every day. At the time, warlords carved up the land and fought among themselves, while powerful enemies loomed beyond the borders. The people lived in misery, barely able to survive. To protect himself, Chen Feng begins drilling his troops. As his territory grows, the supplies he receives from sign-ins get better and better. Warlords attacking? I'll blast them to smithereens with my Italian cannon! Foreign enemies joining forces? I'll give each of them a Little Boy and blow them to ash!
