- Description from novelbuddy

Bob was a good guy. He had done everything you were supposed to do. He exercised, he kept to a healthy diet, he'd studied hard, gotten excellent grades, and was working towards his masters. Somehow, things just weren't working out for him like he'd been told they would. He was stuck in a thankless position, constantly passed over, and it seemed that the only being on earth that cared about him was his cat.

Then things got worse.

Never back a man into a corner unless you want to find out just how hard he can fight.

After being hit by thunder while sleeping with his phone, Frank awakened to his Ability, being revealed to a new world of wonders and dangers and countless other Worlds filled with Chaos through his World Traveling System!

He discovered that Earth wasn't as he had thought it to be.

What he always believed to be fiction was real.

People with Abilities existed everywhere.

Powerful entities controlled the entire world behind the scenes.

Dungeons covered the world and Monsters roamed freely, bringing chaos behind the facade of a peaceful society.

However, Frank will not only have to face the dangers of his homeworld, but the unpredictable ones of countless others...

He has no choice, as he has been bestowed the Title of World Traveler!

Accompany Frank on his journey to grow as a person, to save his homeworld, and to conquer the multiverse!

This is a novel with a main character with emotions that develops more as the story advances, it is not about a lifeless drone that mindlessly kill things without any actual plot nor character progression!

In this novel Frank slowly changes, from a World Traveler to a World Conqueror! From a common man to someone who carves his way through challenges or enemies!
