"You said you can make drinkable water using this metal barrel am I right?" "Yes, I just need some tubes and a container for the water" "If that's what you want then I'm pretty sure that I've seen a hose here somewhere, Oh I found also there was a water jug nearby let me just get it"
Yuki runs to get it, "What the hell? How can you be so lucky?" Haru gets inside the forest to get some firewood when Yuki gets back and saw her carrying those big wood he immediately runs towards her to help her carry the wood, "I'll do it, It looks heavy after all" Haru looked at him with a worrying eye "A-Ah I'm just doing this because if you get hurt I can't use you anymore got it!?"
"Puff, You sure are weird Yuki" Yuki's ears turn red a little, and Haru saw it and smiled. They got back to the shore. "So? How are you gonna make water with A metal barrel, A hose, and a rubber-made water jug?" "I read a book about some survival guide, It said that to make drinkable water from the ocean water is by evaporating the ocean water and transferring it to another container" Yuki didn't understand so Haru just show it to him
"I'll be needing your help to fill the barrel, only half of it got it?" "Ok?" while Yuki is putting water into the barrel Haru starts preparing the fireplace, by digging a bit into the forest soil and putting flat rocks for the container to be in.
Yuki And Haru carry the barrel toward the fireplace, After putting it in its position "Yuki, Can you start a fire?" "Sure" The barrel has a little box cut to its top to where the hose can go through, and so is the water container, by putting some cut towel to the hose for the steam does not leak and cover the unwanted cuts from both container.
This process is called Desalination the process of getting salt out of saltwater so that it's drinkable, by boiling the water, then catching the steam, leaving behind the salt. "Now we'll just wait for it to steam" while waiting Yuki makes a hommock by using the fish net he found, He makes two.
"It's already Afternoon, I'll just go look for food around the shore"
