Back to Earth...Again

Leon woke up a few hours later, he felt very well rested and refreshed, stretched his body, he had been fighting nonstop, cause even after clearing the dungeon, he went back to the city, only to find out about the dungeon breaks and here he was.

Looking around, he found himself out in the open, not the place he slept, but he didn't think too much about it.

Suddenly he began to hear the system's voice in his head.

[You've gotten a D rank world, and it looks like Zeus is now the sovereign of this world, At the pinnacle of this universe overseeing overseeing everything. Since you've gotting a sentient world, you'll have to defend it's rank every ten years]

'What?!' Leon was shocked, he was being introduced to something. The system seemed extremely infuriated for some reason. But that wasn't why he was shocked, from the system's statement, Leon could deduce that there's many more sentient worlds out there.
