Hao Yong, a modern traditional Chinese medicine acupuncturist, accidentally transmigrates to a war-torn ancient frontier and becomes the lord of a poor little city. Facing the triple crises of an enemy state’s threat, internal rebellion, and a spreading plague, Hao Yong activates the Meridian Civilization System, which lets him turn acupuncture treatments and infrastructure achievements into civilization points. He must cure the plague, strengthen the city’s defenses, and improve public morale within three months, or the enemy army will raze the city. Hao Yong wins the people’s hearts by treating them with acupuncture and uses the System to acquire technologies such as cement and stirrups to strengthen his forces, but this earns him the jealousy and hostility of conservative nobles. As the enemy army closes in, Hao Yong must choose: sacrifice a healer’s compassion and use poisoned needles, or uphold his medical ethics but risk losing everything? In the end, by combining acupuncture with modern tactics, he not only defends the city but also establishes a new order founded on medicine.
