In the far north, there is thousands of miles of ice, and the flames are cut off. Yun Lan was originally an exiled frontier cavalry, but in the midst of extreme cold and hunger, he glimpsed the miracle of sleeping under the glacier for thousands of years. Natural disasters are looming, wolves are waiting around, bonfires are difficult to burn, and life is as thin as frost. But instead of using fate as a cage, she used desperate situation as a furnace, tempering the ruthless harsh winter into a sharp edge to defeat the enemy. Yunlan vowed to lead a forgotten remnant army to regain his own dignity in the ice and snow with blood and wisdom. Her enemies are not only cold nights and famine, but also betrayal and greed lurking in the hearts of her colleagues. And the mysterious miracles deep in the polar regions are quietly stirring people's desires. Every decision is a dance on the edge of life and death, faith and doubt. Can Yunlan use his will to refine himself to ignite the glimmer of hope and tear apart the boundary between life and death that is restricted by ice and fire? This is an epic of survival on the ice that sharpens faith with sharp edges and challenges fate with miracles.
