The calamity strikes the world, and everything begins to change drastically around our main character. What he once believed was fiction becomes reality as system windows appear before his eyes, and the world transforms into a hell governed by the law of "survival of the fittest." The ML Aethelric Caelan fights to survive in this new world alongside his loved ones while maintaining his principles. He is no ordinary youth—possessing extensive knowledge across a wide range of subjects and formidable combat abilities, he leverages these skills in an attempt to transform this harsh world into a peaceful place where all organisms can coexist.
