The sun disappears and the blood moon is in the sky. All species evolve under the blood moon, except humans who turn into zombies.
Lin Chen, a senior high school student, accidentally obtained an SSS-level black source crystal during the blood moon disaster at the swearing-in ceremony, and awakened his metal manipulation ability. And his nemesis, sports student Zhao Lei, has acquired S-level abilities and is his enemy everywhere.
In the last three years of the last three years, mankind has established a nine-level hierarchical system. Lin Chen fought his way out of school, experienced conspiracy in the shelter, internal fighting in the military, and grew up side by side with the mythical beast White Tiger. Finally, he broke through to the ninth level and crushed all opponents in the national war.
When the world falls into eternal darkness, only metal is the sharpest light in his hand.
