In the twenty-seventh year of the Republic of China, the ice city was in turmoil. As the deepest secret planted by the military commander, Lin Yan was betrayed by his superiors after assassinating a senior Japanese official. He became an "abandoned son" who attracted firepower. He was trapped in a tight siege and ran out of ammunition and food. Just when the Japanese and puppet troops were grinning and preparing to close the net, the [Infinite Arsenal Sign-in System] suddenly awakened!
Assault rifles, C4 explosives, and even Katyusha rocket launchers are all available. Just when the head of the Special Higher Education Course thought he was catching a turtle in a urn, what greeted him was an unprecedented barrage of firepower. Lin Yan transformed into an ice city nightmare. During the day, he was a mysterious comprador with many faces, and at night, he was a Shura wielding Gatling and sweeping across the gendarmerie!
Boss Dai, the military commander, was horrified to discover that the abandoned son he had abandoned could manage the firepower of a mechanized army all by himself! The top officer of Bingcheng looked at the ruins all over the ground and fell into deep self-doubt: "You call this a latent agent?!"
