In the 32nd year of Jiajing's reign, Japanese invasion was rampant along the southeast coast. The protagonist is reborn with the "Modern Arms Exchange System", which contains a full range of weapons and equipment from the Cold War to modern times, from pistols to tanks. Every time you kill Japanese pirates and complete anti-Japanese missions, you can get "military merit points", which can be exchanged for weapons and ammunition, military technology and special operations knowledge. The system has a technology tree that needs to be unlocked step by step, from light weapons to heavy firepower to modern tactical systems.
