Jason was still sceptical about the apps ability to change the world and thought of doing it again. Maybe this time it could work and the previous thing was only a misimput.
Loading up the app again and finding something to change the world, Jason got a hard on when he thought of the endless possibilities. People surely saw his boner and made a few passing remarks about him looking up porn in a public space. But Jason did not care.
When Jason found what he was looking for, he ended up being really giddy with excitement. Reading through the sentences, he made sure that it could work for what he was planning to do.
Getting up two separate sentences that read 'Humans are the dominant species on earth' and 'merfolk only appear in fiction'. Jason altered the two sentences so that 'merfolk are the dominant species on earth' and 'humans only appear in fiction'. In the next second, Jason could feel that something had certainly changed.
Again his Hope's were disappointed as he still found himself deep below the sea in the mer-mall. All the other merfolk were swimming and chatting as they went to separate shops, going by their day to day lives.
As Jason looked to his Mer-phone to see if the app had malfunctioned again, a small pop-up had appeared on it. The notification read 'all change tokens had been used up, uninstalling the application now'.
"Wait, I had a limit to the amount of sentence I could change. What a rip-off, the app barely did anything worthwhile besides change a few merfolk, it can't even change anything to huge." Jason got annoyed at the app and put his mer-phone in a small pouch around his chest.
As Jason swam off through the Mer-mall, his mind had become unaware of the massive change he inflicted onto the world. Bow that humans don't exist, all of the mainland is unknown. Civilisation now lives in towns and cities at the sea bed, while the continents are free with rich and diverse wildlife.
While technology and other things that humans had were still around, they had taken on other forms. Phones were now Mer-phones, TVs hadn't changed much except being able to work underwater etc.
One noticable difference about the new world is that the main land is completely unexplored except for the coasts. Instead of 90% of the oceans being unexplored, 90% of the mainland is unexplored. The seas have become completely charted and are about 99% explored.
But ignoring that, since the app had run out on Jason's phone, a new individual would get the app on their Mer-phone. But who gets it?
