Lin Xiaofan transmigrates to the era of the War of Resistance, and that's not all: he becomes an eight-year-old child. Fortunately, he has the 999 System. Every task he performs raises the relevant skill to its maximum level, and completing System missions also rewards him with all kinds of weapons, industrial machinery, and more.
From then on, a strange sight appears on the battlefield: an eight-year-old regiment commander leads his troops to unstoppable victories.
P.S. The War of Resistance in this book takes place in an alternate parallel world. If anything differs from historical fact, don't read too much into it. This is a feel-good story, so just enjoy the ride.
