Survive in the Puzzle World

The world we originally lived in has changed. On this day, an advanced civilization that no one has ever seen brought destruction and rebirth to the world. The original animals here began to grow in size. The original continent was invaded by a dark night, accompanied by earthquakes and the collapse of buildings. Earth-shaking changes occurred. The world in the novel shone into reality, no, merged into reality, and things that should not have appeared appeared. The huge monsters that exist in the world. At this moment, technology, magic, ghosts, conjurations... All emerge in this world. Following this, the continent is divided, and continents that do not belong to this world are mixed in every corner out of thin air. All continents are not like a complete continent suitable for survival. They are like a huge and boundless puzzle, which is disrupted into a mess that is inconsistent with common sense.
