Time flies, 5 days pass in a hurry, no ships are found in the vast sea, and the boat is still drifting alone.

The sun was still so dazzling and scorching, and staying in a small space for a week was a great mental torment.

Fortunately, I have the company of my friends, if I am alone, I am afraid that I will already be depressed and become ill, or I may not be able to find a short-term view.

After a few days of wind and sun, Han Lingshuang turned a little darker, because there was no fresh water to clean personal hygiene, so he could only use seawater.

Although it makes no difference to use, the evaporation of seawater leaves a thin layer of salt on the body.

"Goodo......"

Han Lingshuang gently took a sip of some turbid water, which was flowing in the cabin and was sucked and wrung dry with a mosquito net.

Now there is a desperate thing, the water on the boat is less than 5 liters, and this fresh water resource can only last for 3 days at most, even if it is saved.

Although the sails can catch fresh water, the number is extremely limited, and this day is only about milliliters, and feeding a small baby is estimated to be effective.

You know, there are two adults and a dog on the boat now, and the slow-growing supply doesn't do much.

But in this harsh environment, a drop of fresh water is good, and even a small amount of fresh water is precious......

Han Lingshuang had always paid attention to the situation around her, and there was nothing in the vast sea area.

Not only was there little fresh water, but also food, and the two sea monsters were fighting that night, losing some of the food on the boat.

Now something had to be done, and Wu Yi was ready to make a still, and there was still a little charcoal on the boat.

"Pervert, how many more days can we last?" There was a trace of despair in Han Lingshuang's clear autumn water eyes, and a wry smile rose at the corner of his mouth.

I've tried fishing these days, but I've found nothing, as if there were no fish in the area, including the rampant sharks.

As for the basket net, neither of them dared to continue to place it, the last time it was the basket net that attracted the king squid, and that time it was almost finished, if it weren't for another unknown creature to prey on it, I'm afraid they would have turned into feces by now.

Without food and fresh water, the fragile life of human beings will soon come to an end.

"Don't worry, with me, we will live. Wu Yicai grabbed Han Lingshuang's little hand, and touched her forehead, and he could see the delicate face of the beautiful woman up close, but there was a trace of sorrow on this flawless face.

Han Lingshuang didn't speak, just nodded lightly, in such a difficult environment, she would have collapsed, if it weren't for Wu Yicai and Wangcai's company, she might have given up long ago.

"Now we have a lot of tools to get water, that is, to turn seawater into fresh water that we can drink!" Wu Yicai's mind contains a lot of knowledge about the conversion of seawater into freshwater, and now is the time to use it.

"Do you have a way?" Han Lingshuang said in surprise, a touch of unhappiness rose on her random little face, "Why don't you use it sooner if you have a way?"

"This method is gnawing at the old book, it is estimated that it will not be long before our resources will be exhausted!" Wu Yicai's vicissitudes of life were full of bitterness.

Wu Yicai's inner method of taking water is distillation, using charcoal as fuel to boil seawater, and when the seawater boils, a large amount of water vapor will be produced.

Although seawater contains a lot of salt, the evaporated water vapor can be decomposed with the salt, which means that the water vapor produced by boiling is fresh water.

Although this distillation method can make fresh water, the resources consumed are huge, and the charcoal on the boat is a consumable, and it is gone when it is exhausted.

But these are extraordinary times, the scarcity of freshwater resources will be a big threat now, life is inseparable from water, in order to continue to survive, these precious resources can only be consumed.

Under the action of the convex lens, the fire was successfully ignited, and it would take some time for the charcoal to be completely ignited, so Wu Yi filled the iron pot with seawater and prepared to boil the seawater.

There is also a small tarpaulin in the shelter, which can be used as a tool to keep water vapor out.

Put the iron pot on the fire to boil water, and use three volcanic stones to form a simple stove, which can not only stably place the pot on it, but also absorb the heat of the fire, and can always heat the water in the pot.

Then build a shelf with some bamboo strips, cover the top of the pot with a tarpaulin in an oblique shape, and place a container for storing water in the lowest place.

"Is this a still?" Han Lingshuang looked at the strange object that Wu Yicai was fiddling with very curiously.

Wangcai was also very curious about this strange object, lying on the ground and looking sideways, as if sensing the heat of the flames, and it had an instinctive fear of the flames.

As if frightened, Wangcai ran to Wu Yicai and Han Lingshuang for comfort, and his big eyes were full of confusion.

Stretching out his hand to soothe Wangcai, the hair on its head is very smooth, very comfortable to touch, and this thing is also very enjoyable and squinting.

"The flame boils the seawater, and the rising water vapor is blocked by the impermeable tarpaulin, and a large amount of water vapour collects all the time, and then the tarpaulin is obliquely shaped according to the principle that the water flows downward. Wu Yicai pointed to the bottom of the plastic bottle under the tarpaulin, "The accumulated water vapor will slowly increase, and then follow this diagonal line to the lowest point, and then collect it." ”

Wu Yicai explained the distiller he made, which is a very practical thing that can collect some fresh water.

……

"Look there are a lot of seagulls over there!" Han Lingshuang was attracted by a large group of seabirds on the seashore in the distance, they were flying very fast and flying towards this direction at great speed.

"It's these seabirds preying on fish, and there are big schools of fish chasing the small fish under the water, and the small fish have no choice but to jump out of the water and glide, although they can escape the big fish underwater, but eventually there will be seabirds attacking. Wu Yicai is very aware of this phenomenon, and has seen it many times in the animal world.

Dolphins or tuna gather together to hunt flying fish, and these fish have evolved skills to survive by jumping out of the water, using their tails as a propulsion, and spreading their evolved fins to glide through the air.

This flying fish has evolved wing-like fins that glide through the air and are said to be able to glide up to 400 meters.

Although this fish is very powerful, it is still tragically preyed, there are fierce carnivorous fish in the seawater, and it is a fierce seagull that has just flown out of the water to greet you.

Two species cooperate to hunt one species, one in the sea and the other in the air, even the Saint Seiya can't compete with such encirclement and suppression.

Seabirds are getting closer and closer to the boats, and you can see fish gliding in the sky, and there are really a lot of them.

And the creature chasing behind the small fish is a large group of dolphins, they are beautiful and beautiful.
