Modern Weapons Cheat in Fantasy World

Marcus Manfred's aspirations of a military career were tragically cut short. However, fate intervenes, offering him an extraordinary second chance through reincarnation into a world dominated by magic. Upon awakening in this new realm, Marcus receives a divine proposition: he is granted the Military Weapon System. This unique gift bestows upon him access to Earth's most advanced military technology, including firearms, tanks, fighter jets, and even warships, an arsenal completely alien to this fantastical world. This immense power, however, demands a price. To expand his formidable arsenal and maintain his technological advantage, Marcus must undertake dangerous quests. He will fulfill the urgent needs of struggling towns, cater to the ambitions of nobles, and aid besieged kingdoms in their desperate struggles, all in exchange for the resources to fuel his modern war machine.
