When the world turns to dust, surviving becomes the most luxurious dream.
"Holy City", a last pure land of mankind that only exists in rumors, is the goal of all survivors.
To achieve this goal, Zhou Ke calculated every step of his life with wisdom, while his brother Huo Xiyan used his scarred body and a fire ax to cut off all dangers for him. There is a scar on Huo Xiyan's left eyebrow. It is a medal left when he blocked Zhou Ke's sharp claws, and it is also his lifelong vow - as long as he is still standing, Zhou Ke must live.
They form a team, travel through the dead city, fight against deformed monsters, and beware of the human heart that is more sinister than the monsters. Zhou Ke's idealism is a weak spark in this gray wasteland; while Huo Xiyan's cold reality is the only barrier to ensure that this spark is not blown out by the strong wind.
But when the outline of "Holy City" gradually became clear, a cruel truth also emerged.
Is what they are pursuing the rebirth of mankind, or a carefully woven lie? And has the true fate of the brother Huo Xiyan vowed to protect him to the death been already written?
