break the sky

The story is set on post-apocalyptic Earth. A hundred years ago, the "X virus" broke out. Transmitted through liquids and gases, it had an extremely high mortality rate and quickly infected nearly all life on Earth. The human population plummeted from 7 billion to 3 billion, but those who survived discovered their bodies evolving, becoming faster, taller, and stronger. Tragically, animals also began to evolve, becoming even more powerful than humans. Bullets couldn't penetrate their armor, and even nuclear bombs couldn't threaten high-level monsters. With modern technology practically useless, warriors rose to prominence. Through training, these warriors mastered immense powers, allowing them to battle monsters tens or even hundreds of feet tall. Humanity lost all its oceans and islands, including Australia. Ultimately, only five nations remained: these five great powers formed humanity's 23 base cities. Decades passed, and it wasn't until the rise of the protagonist, Zorro, that the balance between humanity and monsters was finally broken.
