Guarding the Land Will Never Be Destroyed: Once Upon a Time, There Were a Group of Gatekeepers

In the Setting Sun Fort in Liaodong, young Qin Zhao witnessed his adoptive father being martyred in the fort and went south to Ji Town with a bronze token. On the way to the snowy field, he gathered the archery orphan Shen Mo, Cheng's builder Gu Yan, and the Jianghu wanderer Zhao Ritian. Each of the four had skills in craftsmanship, archery, martial arts, and medicine, and rushed to the important town of Jiubian. However, the border has long been empty: the grain and grass have become moldy, the tunnels have been tampered with, the beacon smoke tunnels have been narrowed, and the false edict of "abandoning the border and moving south" has been scattered among the army. In the court hall, Wang Song, the Minister of Household Affairs, deducted wages from the border and colluded with people outside the Great Wall; in the dark, Cheng Tianshu, the orphan of the Cheng family, had been dormant for hundreds of years, forcing the traitor to reveal himself when the Great Wall collapsed. Tumut's poisonous miasma entered the city along the underground river, Chahar's cavalry crashed into the west wall, and Uliangha's cavalry attacked day and night. In the desperate situation of running out of food, Qin Zhao and the exiled doctor Su Yuanqing used Chinese herbal medicine and nomadic medical techniques to prepare an antidote; Gu Yan improved the five-color wolf smoke based on Cheng's fragments, doubling the early warning efficiency; silently squatting at the shooting position, using the skill of breaking the bow and stringing it back to snipe the enemy chief from a distance; Zhao Ritian guarded the refugee village alone, stopping thousands of cavalry by himself. From the captain of the scout to the commander-in-chief of the nine sides, from the first encounter with the heroic spirit in the medical camp, Qin Zhao and Su Yuanqing made a lifelong promise - Qin Zhao and Su Yuanqing coexisted in adversity and had two-way redemption. The emotional line was bound to the main line of war strategy. There was no triangle entanglement, only the life-and-death agreement of "the city is not broken, and the fireworks are watched together". A three-volume epic: Lonely Shadow in the Border Town, Tempering Fire at the Pass, and Using the Body as a Barrier. In the final decisive battle at the Great Wall, Cheng Tianshu put aside his century-old obsession, Qin Zhao coordinated the alliance of six towns to repel the coalition forces, the injustice was vindicated, and border trade was opened. Keep the soil, keep the heart, keep the art, keep the good, keep the harmony. A realistic ancient war epic that uses the Great Wall as a barrier of flesh and blood to describe the growth of grassroots generals, the inheritance of craftsmanship and medical skills, and the reconciliation and symbiosis of nations.
