Sign-In During the War Against Japan: A Squad Every Day

[War of Resistance against Japan] + [raising a massive army] + [sign-in] + [killing Japanese invaders]

Chen Ye transmigrates to the war-torn year of 1939. In a desperate situation, he unexpectedly awakens the Anti-Japanese Sign-In System!

Each daily sign-in unlocks a complete combat squad: rifle squads, machine-gun squads, mortar squads, and reconnaissance squads, each arriving with all their equipment, personnel, and tactical training ready to go.

From standing alone to raising an elite company, then building an invincible force, the protagonist takes his System squads from north to south. They hold positions, destroy strongholds, raid supply convoys, and wipe out Japanese troops. Building from small units, they turn minor victories into major ones, earning a fearsome reputation on the front lines and behind enemy lines with modern tactics and an iron will.
