In a post-apocalyptic wasteland where human civilization is on the verge of collapse, an unknown restricted area called the "Dark Forest" devours all explorers. Legend has it that deep in the forest sleeps a "mechanical prophet" who knows the past and the future. When young Lin Mo stepped into the restricted area in search of his missing sister, he discovered that the so-called prophet was actually an ancient war weapon with self-awareness. It predicted a catastrophe that could destroy the remaining human beings, and the only hope was hidden in Lin Mo's forgotten genetic code. Will he become the puppet of the prophet, or will he harness the power of steel and fight his way through the doomsday wasteland?
