You've Traveled Through Time with the System, so Why Don't You Play the Devil to Death?

Lin Zifeng, the modern king of special forces, travels back to the war-torn era of the War of Resistance Against Japan. Defeat the Japanese, bravely break into enemy formations, kill all directions, and your contribution points will be recorded in your account. No supplies, exchange! Lack of weapons, exchange them! Want food? Exchange! Not strong enough? Exchange! Lin Zifeng, who was already invincible, armed himself with the help of the system to "the anger of both men and gods", and developed a guerrilla force with only a dozen people and a few broken guns into a powerful force that frightened the devils and killed them until they had nowhere to escape. My tempo is not particularly fast, but it is neither boring nor uninteresting. I aim to take it slowly and enjoy it continuously.
