Feeling Excited

Seeing the System prompt inside his head, Nile couldn't help but jump and punch the air in excitement. However, a moment later, he was frozen solid as he suddenly thought of something terrifying. 

'Isn't this too good to be true?' 

'Wait, haven't they just evolved yesterday? How come they can evolve again after just a day of eating?' 

Confusion appeared on his face as he thought of a ridiculous scenario that might happen.

'If this is the case, won't the animals become stronger and surpass those who have evolved first? An evolution after a day...'

'No, it seems only to be the case for my pets. Because if it's not, then I'm afraid those animals escaping from the zombie pets horde previously probably won't be escaping, and will instead fight back.' He thought in defense.

'Hmmph! What's with the System asking permission for my pet's evolution? Isn't that a must already?'
