All Races Are Awakening and I Will Subdue the Heavens with the Human Race

The top international mercenary traveled through time and became a high school senior in the post-apocalyptic world. He originally wanted to rely on his killing skills to save himself, but was saved by the "last guardian of the human race" with white hair and red eyes and blood all over his body. She said, I am the only hope for humanity. But in her broken armor and empty eyes, I saw a shocking secret—the so-called "battlefield of all races" was nothing but a well-planned scam! Our human race is just a "gu" kept in captivity by some mastermind behind the scenes! And I have awakened to the only law of cause and effect that can reveal the truth. For her to no longer fight alone, for my dead brother, and for tearing apart the lies in this world! I will use cause and effect as a thread to peel off the cocoon and uncover the chess player hidden behind all races! "In this life, I will open a way for the human race!"_-Not only for survival, but also for truth and dignity! This novel and its characters are purely fictitious.
