Wuxia: I Have a Material Duplication System

Wang Baichuan traveled through time to the end of the Ming Dynasty, when gun smoke was everywhere and the people were in dire straits. The major political forces were divided into one party. At that time, he was just a poor man. Unexpectedly, the material duplication system was accidentally activated. "System prompt: 20 bags of food, 200 sets of armor" Hahaha, I got this precious thing by accident. "Now I will make a fortune, hahaha, I am invincible." "What, you, a small family, dare to fight against the Xiongnu and kill the enemy?" The emperor knelt down and begged for help, "Brother Wang, why don't you help me and give me some food and weapons?"
