Anti-Japanese War: I Have Unlimited Copy Function

[Slight system + Anti-war + Troop raising flow + Independent development + Backup] Zhang Zilong was accidentally reincarnated into a bandit village during the Republic of China. Qingshui Village was annihilated under the siege of the Japanese Kwantung Army. Zhang Zilong and his remaining troops broke out of the siege of the Japs and fled into Tianjin. From then on, the Japanese in the Tianjin Concession had trouble sleeping every night and lived in fear all day long. Zhang Zilong is also bound to the 'Jedi Counterattack System' through the unlimited copy function By mass-copying all kinds of advanced weapons and equipment, they finally had the capital to fight with the Japs' heavy firepower.
