Forging a Sword for the Nation: I Build a Peak Huaxia

Liu Zihong, reborn as a member of the Weapons Research Institute, declares: "Truth is only within range of artillery!"

Like a mushroom with instructions written only in Chinese;

Like a reconnaissance drone that can carry an extra 200 kilograms...
