She stood up and put on her own clothes, and handed the coat back to Jun Mo Shang. He took it and put it back on, then lifted up her left sleeve. Seeing the wound tied with the strip of cloth, his face was filled with distress, "It still hurts."
What?"
"It doesn't hurt." She said calmly.
Youqi came over and looked at her wounds with a frown, "Yun'er, when did you get your left wrist injured? Why didn't this prince know?"
"It's okay, I just accidentally got hurt by a sharp stone." She wouldn't tell him that it was her own cut. "It's just a small injury. It will be healed soon." Withdrawing her hand, she stood up and looked at the twenty pits.
Then I walked to the foot of the small rocky mountain ahead and saw a leaf bowl filled with water dripping from the cracks in the rocks.
The dew collected and the water in the dripping leaf bowl are enough for three people to drink for a day.
There is no fresh water to wash your face or take a bath, and the clothes on your body have been soaked in seawater and contain salt, making them uncomfortable to wear. There is no other way but to make do with it.
After thinking about it, she scooped some water with fresh leaves, picked some clean grass, chewed it slightly, rubbed the chewed grass on her teeth with her index finger, took two more mouthfuls of water and spit it out, which was considered a simple brushing.
A tooth.
The two men also imitated her and cleaned their teeth. They knew that fresh water was not easy to come by, so they both saved water.
After brushing his teeth sparingly with water, Jun Youqi felt a little emotional, "I have now realized that water is more expensive than oil, no, it is more expensive than gold. In this damn place, food and drink are the only ones that are useful.
Money is worthless."
"Actually, there are two other ways to get fresh water on the island," she said.
Both men were a little curious, and she said expressionlessly, "The first is the distillation method, which is to put seawater in a container, put it on a fire and boil it, then put a lid on the container, and the water vapor will stick to the lid and condense.
It becomes fresh water."
"What is a container?" Qi asked.
"It's just for holding things."
"It's like a pot. There is no pot or lid here."
"If you are diligent, you can carve a stone pot and replace the lid with a large leaf. Anyway, the water vapor will condense if it gets on it."
Jun Youqi thought for a while, "The collected dew and water dripping from rock cracks are enough to drink. The method you mentioned is too troublesome. Moreover, the amount of fresh water obtained is very time-consuming and small."
"Well, that's what I said." She said, "I don't plan to use it. However, it would be good to have a stone pot to cook something with."
"Other than that, is there any other way to get fresh water?" He blinked his beautiful dark eyes at her, "Yun'er, are you talking about waiting for it to rain? If it doesn't rain for a few days, you'll be thirsty.
Dead people."
"Of course not," she said simply, "it uses reverse osmosis to get fresh water from seawater."
One was evil, the other was dark, and both looked at her with confusion.
She was really too lazy to explain such a high-tech thing. Even the two ancients didn't understand it. They all gave it a heads-up, and it seemed unkind not to explain it. So, she simply said, "It's just using the semi-permeable membrane to choose the transparency."
It uses the principle of water resistance to prevent salts and other substances from passing through, allowing seawater to pass through, filtering salts and other substances, and filtering out fresh water."
"What is a semipermeable membrane?" Jun Youqi was very surprised, "According to your statement, if there is a semipermeable membrane, wouldn't seawater become fresh water at any time using this osmosis method, and the fresh water will be inexhaustible.
Inexhaustible?"
Sure enough, she was smart. She said, "There are many semipermeable membranes, which are the thin membranes in eggs, fish fat, casings, animal bladders... there are many. But they need big semipermeable membranes. Obviously, you can find them on the island.
