The Legendary Dungeon Master

The Legendary Dungeon Master He thought transmigration would give him a second chance at life. Instead, he woke up in the body of a weak and penniless adventurer in a world ruled by magic, monsters, and deadly dungeons. With no powerful bloodline, no legendary weapon, and barely enough strength to survive, he decides to become a Dungeon Hunter. But everything changes during his first expedition. Trapped inside an unexplored dungeon, he discovers a mysterious ability that should not exist. He can control the dungeon. Monsters recognize him. Hidden rooms reveal themselves to him. And the deeper he ventures, the more powerful his dungeon becomes. But dungeons are not merely places where monsters live. They are part of a much older mystery. As he grows from a powerless adventurer into a legendary Dungeon Master, he will uncover secrets that could change the relationship between humans and monsters forever. To survive, he must conquer dungeons. To become powerful, he must command monsters. And to uncover the truth... He may have to challenge the entire world. — Description from novelcodex.org
