Liu Bei, but not the Liu Bei you know.
Before time travel, he was a contractor, and after time travel, he was tied to a conqueror system. The system does not distribute food, grass, or troops. What it distributes are all things that are not available in this era-hard tools, special tobacco and alcohol, sunglasses and gold chains, and a tablet computer filled with "study materials."
Guan Yu stopped reading "Spring and Autumn" and learned to shoot from Liu Bei. The Qinglong Sword was only used for cutting tobacco. Zhang Fei doesn't like fighting and prefers to hear noises. He has a gun on his back and Liu Bei calls him a prodigal every time he fires. Zhuge Liang did not read military books, but studied the weaknesses of human nature with illustrated miscellaneous books. After reading them, he wrote his thoughts after reading them for Liu Bei. Zhao Yun looked serious on the surface, but that night when it was his turn to watch the tablet, he practiced shooting until dawn.
When the three brothers go out, they must wear sunglasses and hang gold chains. The enemy called them "gold chained people" and said they were nondescript and like nouveau riche. Liu Bei laughed after hearing this: What happened to the nouveau riche? Not only do I want to break out, I also want to change the rules of the entire Three Kingdoms.
There is no martial ethics in fighting. If you can kill someone in secret, you won't be upright; if you can solve it with your mouth, you won't use a guy; if you can use special supplies to instigate rebellion, you won't need a single soldier. Warm wine and kill Hua Xiong? No, shoot Hua Xiong with one shot. Three heroes fighting Lu Bu? No, three people interviewed Lu Bu and asked him if he was willing to change jobs.
