[Red Alert] [No mass-producing troops] [Infrastructure] [Superpowers] [Monster hunting] [Sneaky male lead] [No female lead] Jiang Haochen survived in the apocalypse for three years before his companions betrayed him.

Prism Towers, Tesla Coils, and Grand Cannons created the ultimate arsenal. Riflemen, Heavy GIs, and Rocketeers: Red Alert forces surged across the land.
