War of Resistance: Combining Military Branches, I, Chu Yunfei, Go It Alone!

After transmigrating into the body of Chu Yunfei, he awakens a troop-fusion System. [Decisive and ruthless, with plenty of satisfying action] Fusing three low-level soldiers into one high-level soldier is a shortcut to strength, but it also forces him to face a cruel reality: human lives are as worthless as weeds! Unlike the Eighth Route Army, he isn't bound by countless rules and restrictions. As long as it brings victory and doesn't harm his fellow countrymen, he will use any means necessary. The fused troops come automatically equipped with weapons and ammunition, and are absolutely loyal to Chu Yunfei! To his great surprise, even three Japanese prisoners can be used in the fusion, with different evolutionary paths to choose from! These Japanese soldiers have the blood of our troops and civilians on their hands. How could Chu Yunfei possibly accept them so easily? But when he sees one of the evolutionary paths, the gloom in his heart immediately lifts, replaced by barely contained excitement. That's it! Give them a taste of their own medicine. This is the true meaning of sustaining war through war! From then on, Chu Yunfei's army becomes an unstoppable arrow, sweeping across the battlefield. Their goal is to destroy the enemy's fighting strength, and they advance relentlessly, mopping up and wiping out the Japanese invaders!
