Liu Bei, but not the Liu Bei you know.
Before transmigrating, he was a construction contractor. Afterward, he gets bound to a Conqueror System. The System doesn’t provide grain or troops. It gives him things this era has never seen before: firearms, custom cigarettes and liquor, sunglasses and gold chains, and a tablet filled with “educational materials.”
Guan Yu stops reading the Spring and Autumn Annals and learns to shoot from Liu Bei. His Green Dragon Crescent Blade is only used to cut tobacco. Zhang Fei loses interest in fighting and just wants to hear things go bang. He keeps a gun tucked behind his waist, and Liu Bei calls him a wastrel every time he opens fire. Zhuge Liang gives up on military manuals and studies human weaknesses in illustrated miscellanies, then writes Liu Bei a book report afterward. Zhao Yun acts proper on the outside, but when it’s his turn with the tablet, he practices shooting until dawn.
Whenever the three brothers go out, sunglasses are a must and gold chains are mandatory. Their enemies call them “the Gold Chain Gang,” saying they look like nouveau riche hicks who don’t belong. Liu Bei laughs when he hears this. “So what if we’re nouveau riche? I’m not just getting rich. I’m changing all the rules of the Three Kingdoms.”
There are no rules in war. If you can take someone out with a dirty trick, don’t fight fair. If you can talk your way out of it, don’t reach for your gun. If you can win them over with special supplies, don’t waste a single soldier. Warm wine and behead Hua Xiong? No, shoot Hua Xiong. The Three Heroes Battle Lu Bu? No, the three of them interview Lu Bu and ask if he’d like to switch jobs.
