A 90-Year-Old Veteran Returns to 1938 for a Fight to the Death

A 90-year-old veteran returns to 1938 with a System to fight the Japanese.

Not enough bullets? Claim some from the System.

Enemy situation unclear? The System will report it.

From the War of Resistance Against Japan to the War of Liberation, and then to the War to Resist U.S. Aggression and Aid Korea...

In this life, he will fight every battle he ought to have fought.
