In a world where reality and game seemed to have merged, with countless Monsters running rampant, with various Secret Realms and Dungeon Instances, one needed to be strong.

Strong enough to withstand the onslaught of these Monsters!

To do that, each person must go through Profession Changes and madly Level Up!

On the day of his Profession Change, Lu Fan had obtained the Hidden Profession, Dragon Tamer. However, this Profession was deemed the most useless since the Dragon Tamer would need a Giant Dragon to show its true prowess.

What were Giant Dragons? They were deity level existences. Taming them was impossible, thus Dragon Tamer rightfully earned the title of the most useless Profession. Fortunately, Lu Fan was not normal. He was a transmigrator who had awakened a System, the Super Treasure Map System!

With his Giant Dragon accompanying him, Lu Fan could sweep through everything, causing the entire world to tremble.
