Du Bin, a passionate young patriot, transmigrates to a parallel world of the TV series The Bright Sword, where he becomes the commander of the Fourth Company in the Second Battalion of the New First Regiment. He awakens the Iron-Blooded Exchange System on the battlefield and joins Li Yunlong in winning one major battle after another...
Du Bin: Commander, with me around, I’ll get you plenty of top-notch weapons and equipment!
Li Yunlong: You really are my lucky star, Du Bin! Now I can finally stop worrying about running out of guns and cannons!
Du Bin: Commander, I’m going to blow up a pillbox. How about we split the captured supplies eighty-twenty?
Li Yunlong: Sure! Eighty for me, twenty for you...
Du Bin: Division Commander, congratulations on your promotion...
Du Bin: Army Commander, congratulations on another promotion...
Li Yunlong: You little rascal, are you here to rub it in again...?
Swordsmen shouldn't form a team with anyone, and there's no need to recruit troops from outside. The most suitable thing is to kill alone. At most, some equipment can be given to strangers in the name of strangers. It's all so unfair. If I had such an impulsive temper, I wouldn't be doing anything.
