In the chaotic times of the late Ming Dynasty, wars broke out everywhere. The scholar Gu Chuan carries the "Map of Mountains and Rivers and the State of the Country" that has consumed the efforts of three generations of the Gu family. He shoulders his father's dying instructions and embarks on the road of life and death to send the map to the capital. This scroll, which marked the lifeline of the Ming Dynasty's territory, was not only the hope of pacifying the rogue bandits and resisting foreign enemies, but also a reminder to attract defeated troops to pursue and kill them, and the rogue bandits to covet them. He had a brush with death on the muddy official road, and met Sun Chuanting's elite Cao Meng team by chance at the ruined temple inn. He won his trust with the art of being a friend and went together with him. From the thrilling breakout at the Yellow River Ferry to the cliff zipline at Taihang Yangchang Ban, Gu Chuan, with his weak body, used his knowledge and wisdom to carve his way out amidst the light of swords and shadows, and formed a life-or-death alliance with Cao Meng and others in the torrent of troubled times. They not only have to avoid the pursuit and interception of Li Zicheng's army, but also fight against the undercurrent of party disputes between North Korea and China. The map that carries the fate of the dynasty pushes them into the center of the whirlpool that changes the world's structure. This is a lonely journey of scholars and soldiers trudging through the wind and rain, and it is also a tragic song that outlines the mountains and rivers with blood and faith.
