Li Ming, an elite in the field of modern communications, yearns for ancient information transmission methods after working under high pressure. An ordinary debugging of equipment in the computer room unexpectedly triggered a mysterious signal that spanned time and space, and he was involved in the war-torn wars of the late Han Dynasty and the Three Kingdoms. At that time, Li Ming was keenly aware of the key bottleneck restricting the forces of all parties - the extreme backwardness and inefficiency of information transmission. It happened that Cao Cao, the great hero of the generation, was facing off against his powerful enemy Yuan Shao. The military situation was raging, but due to the obstacles of mountains and rivers and the delay of messengers, he repeatedly missed opportunities and suffered terribly. Li Ming quickly found a way to break the situation with his communication expertise that transcended the times. He adapted to local conditions and cleverly used the existing flags in the military to design a simple and efficient visual semaphore system. He also re-planned and activated the beacon network in strategic locations, giving it more accurate and faster communication capabilities. Once this "ancient communication system" that simplified complexity, was efficient and fast, was applied, the results were immediate. Cao Jun's instructions were clear and his dispatch was godlike, completely reversing his information disadvantage. On the stage of the Three Kingdoms, which was full of intrigues and wars, Li Ming suddenly emerged with his unique "communication warfare" ability, strategized, and won thousands of miles, and became famous. His extraordinary wisdom and outstanding ability not only won the respect of the heroes, but also attracted the attention of the beauty in troubled times. The peerless Diao Chan was impressed by her intelligence, Jiangdong's stunning sisters Da Qiao and Xiao Qiao were captivated by her magnanimity, the heroine Sun Shangxiang was also attracted by her style, and the talented Cai Wenji also knew and cherished her.
