Modern courier Zhao Chen accidentally transmigrates to the Eastern Han dynasty's final years. With his quick-dry clothes and cushioned shoes, he narrowly escapes trouble with “Yellow Turban spies.” Using “curiosities” such as compressed biscuits, a solar power bank, and a lighter, he wins over Li Er and Wang Hu and establishes a base in a mountain cave. Relying on his outdoor skills, he sets nylon-rope traps to drive off bandits, finds potatoes to solve the food shortage, and gradually gathers refugees into a force. He recruits renowned generals such as Zhao Yun and Ma Chao, and meets beauties like Diao Chan, Da Qiao, and Xiao Qiao. Cao Cao laments that the realm could be his if only Zhao's treasures were at his disposal, Liu Bei regrets that he will not help restore the Han, and Yuan Shao offers him generous rewards. In the end, Zhao uses modern knowledge to improve farming tools and train his troops, growing from a small mountain force into a warlord. He sweeps aside the other powers and establishes a new government, leaving the whole realm marveling: “That Zhao bandit in strange clothes really changed the course of the Three Kingdoms.”
