Chapter 768 Survival on a Deserted Island 21
She got up and put on her clothes, and handed the coat back to Jun Moshang. He took it and put it back on his body, and then lifted her left sleeve. Is it?"

"It doesn't hurt." She said calmly.

Youqi came over, frowned and looked at her wound, "Yun'er, why didn't my prince know when your left wrist was injured?"

"It's okay, I just accidentally got hurt by a sharp stone." She wouldn't tell him that she cut it herself, "It's just a small wound, it's almost over." Withdrawing her hand, she stood up and looked at the twenty pits I walked to the foot of the small rocky mountain ahead, and saw that the leaf bowl dripping from the cracks in the rock was filled with water.

The collected dew and the water in the dripping leaf bowl are enough for three people to drink for a day.

I just don't have fresh water to wash my face or take a bath, and the clothes on my body have been soaked in seawater, which is salty and uncomfortable to wear.There is no other way but to make do with it.

After thinking about it, she scooped up some water with fresh leaves, picked some clean grass, chewed it slightly rotten, rubbed the bitten grass on her teeth with her index finger, and spit it out after taking two mouthfuls of water. It's a tooth.

The two men followed her example and washed their teeth. They both knew that fresh water was not easy to come by, so they both saved water.

After brushing his teeth in a water-saving manner, Jun Youqi felt a little emotional, "My prince now understands that water is more expensive than oil, no, it is more expensive than gold. In this kind of ghost place, food and drink are useful. Money is worthless."

"Actually, there are two other ways to get fresh water on the island," she said.

The two men were a little curious, and she said blankly, "One is the distillation method, that is, put seawater in a container, put it on the fire and boil it, then cover the container with a cover, and the water vapor will touch the cover and condense." It becomes fresh water."

"What is a container?" Qi asked.

"It's just for holding things."

"Equivalent to a pot. There is no pot or cover here."

"If you are diligent, you can carve and dig a stone pot. The lid can be replaced by a big leaf. Anyway, the water vapor will condense when it touches it."

Jun Youqi thought for a while, "The collected dew and the water dripping from the cracks in the rocks are not enough to drink. The method you said is too troublesome. And 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 either. However, it would be nice to have a stone pot for cooking."

"Other than that, is there any other way to get fresh water?" He blinked his beautiful dark eyes at her, "Yun'er, don't you mean to wait for the rain? If it doesn't rain for a few days, you will be thirsty." dead."

"Of course not," she said simply, "reverse osmosis uses sea water to make fresh water."

One is evil, one is deep, and the two looked at her in puzzlement.

She really didn't bother to explain such a high-tech thing. After all, the two ancients didn't understand it either.They all shook their heads, and it seemed rude not to say, so she simply said, "It is to use the principle of selective permeability of semi-permeable membranes to block the passage of salts and other substances, so that seawater can pass through, filter salts, and filter out the water. Out of fresh water."

"What is a semi-permeable membrane?" Jun Youqi was very surprised, "According to what you said, if there is a semi-permeable membrane, with this osmosis method, wouldn't the sea water become fresh water at any time, and the fresh water will be inexhaustible. Inexhaustible?"

Really smart.She said, "There are many semi-permeable membranes, such as the light membrane in eggs, fish fat, casings, animal bladders... quite a lot. But you need a large semi-permeable membrane, which obviously cannot be found on the island. "
