"Acacia Underwater Town" 

Who would have thought that there would be a small town in the lake and it's not even at a deeper depth....

The mermaid was indeed shocked, but then, she quickly calmed down again. 

For someone who lived in the sea, what kind of strange thing she had never seen before? 

The sea had many wonders! Not to mention just a small town of roots with fish as inhabitants. 

Even if it was a town full of water leaves and the inhabitants were all plants, the mermaid could also accept this fact. 

There were even volcanoes and black holes in the sea, so what's so strange about a small town built of fish by a bunch of tree roots? 

People tacitly named this small town as Acacia Underwater Town and the inhabitants were mostly smart beasts with a little number of uncontrollable monsters. 

Because it was almost impossible for monsters to create a harmonious society, only some evolved monsters with a rather high intelligence lived here.
