In the ancient wilderness, beacon smoke filled the bronze totem. The Cangwu tribe has inhabited the misty forest sea for generations, and is based on bronze forging and totem sacrifice. The leader Mo Yuan is brave and good at fighting, and has the mission of protecting the tribe. However, on the way to explore for resources, he encountered a strange phenomenon he had never seen before - a giant steel bird pierced the sky, billowing steam rose from where it landed, and a strange group of people carried mechanical creations with gears that meshed, breaking the silence of the wilderness.
This group of intruders, who call themselves the "Mechanical Remnants", have brought steam technology that transcends the times. Their metal armors glow with cold light, and the sound of the gear machinery operating forms a strange symphony with the sound of the tribe's bronze drums. Mo Yuan originally wanted to expel these outliers who subverted tradition, but during the confrontation, he was attracted by a woman from the other side's camp who controlled precision machinery and had clear eyes.
The collision of civilizations ignited the flames of war, and questions from tribes, secrets of mechanical survivors, and ancient curses deep in the wilderness followed one after another. Mo Yuan not only had to protect the place where his tribe lived, but also had to face the conflict and integration of two civilizations. Amidst the flash of swords and the roar of steam, Mo Yuan developed a passionate relationship with the woman. The thickness of bronze intersects with the sharpness of gears, the passion of the wilderness collides with the coldness of machinery. They stand side by side in troubled times, staying together in desperate situations, using love and courage to explore the possibility of the coexistence of two civilizations, and uncover the millennium secrets hidden behind the wilderness and steam civilization.
