Two Realms Bound

After the two worlds collided, a strange copy descended on the world. If you win, the land will be fertile and diseases will subside; if you lose, everything around you will be strangely eroded. Governments around the world have blocked information, leaving ordinary people in the dark about the truth. A teenager was involved in a strange copy on the night of his eighteenth birthday. He woke up in an ash-covered wasteland, surrounded only by strange survivors and monsters hiding in the shadows. But he soon discovered that there was another person sleeping deep in the left side of his brain. He was so tired that he said: "Brother, I... Only have you." And outside the cracks in the world, an unknown existence is bearing the pull of the two worlds, silently maintaining the final balance. The old king is dead and the new king has not yet been established. There are people who sit on the throne and are still looking for the power of creation. Someone found this pair of symbiotic souls and sent them into the human world - no one told them why, and no one told them that this chess game spanning the two worlds had just begun.
