ARRIVAL AT ACHAEUS

LUO YAN looked around at the deep blue underwater surrounding him.  There were different fishes swimming around as well as beautiful corals and marine plants.  Everything just felt very real – from the marine animals to plants.  It's like he was indeed under the sea. 

He was kind of in awe again at the meticulousness of the game devs.  They really made sure that everything, even the bottom of the ocean would be as real as possible.  He was certain that if they didn't have items that helped them breath underwater, they would definitely drown.

The item the four of them used was a breathable balloon.  He called it a balloon, but it's more like a coating.  It coated their whole body, allowing them to breathe underwater and also not letting them get wet by the sea water.
