War of Resistance: My Weapons Are Strong, but They Are Limited in Time

Shi Yan traveled through 1937 and became a small battalion commander on the Songhu battlefield. The awakening sign-in system is useless - modern weapons are invincible, but they can only exist for three minutes! Everyone thought he was cannon fodder, but he became a battlefield killer who was feared by the Japanese army. Three minutes of Barrett can snipe the enemy commander! A three-minute rocket launcher can blow up a tank attack group! Three minutes of heavy machine gun can tear apart the Long Live Stormtroopers!
