After I Transmigrated, I Found a Fantasy World

The story of an ordinary person who transmigrates to another world, observes it, assimilates into it, changes it, and is changed by it in turn. The focus of this book is to depict a world of swords and magic through the protagonist's experiences, rather than create an invincible protagonist. Slow-paced, no System, not a power-fantasy story. The protagonist is an ordinary person.
