Guan Yun, a modern young man, mysteriously traveled through time after saving someone who fell into the water. He woke up in the war-torn Qin Dynasty and accidentally became a soldier of the Qin army. Miss Zhao Zhao he rescued turned out to be the niece of Zhao Changshi in the palace, and the two formed a relationship.
In order to gain a foothold in troubled times, Guan Yun relied on modern basic common sense and tenacity to start as a soldier at the bottom. On the battlefield, he repeatedly broke through with ideas that transcended the times - using the principle of leverage to strengthen defenses and predicting enemy movements based on weather patterns. These "unusual" performances allowed him to gradually stand out, and he was promoted from a soldier to a junior colonel. Later, he was noticed and appreciated by the general Wang Jian because he proposed the strategy of "outsmarting rather than fighting head-on" during the siege battle, and took him to his side.
After that, Guan Yun followed Wang Jian to participate in the key battles of the Qin Dynasty to destroy the six kingdoms: he provided suggestions to break the enemy's strong walls and clear the country, used modern logistics management ideas to optimize the dispatch of grain and grass, and gradually grew from an unknown soldier to a general in charge. He contributed to the unification of the Qin Dynasty in his own way, and also wrote the legend of the "comers" in this magnificent era.
