A captain once said to the sailors: "This compass does not point to the north, nor does it point to the north."

The sailor asked: "Where does it point?"

The captain replied: "Poppy Island."

A long time ago, some coastal residents had a wish to grow grains and grains on this desert island. They sown again and again, but were disappointed again and again. Wheat and corn are like weeds, they wither and turn yellow before they can grow into heads. Deserted Island

It was still a deserted island, and nothing was harvested. At the end of the Qing Dynasty, a group of pirates landed on a ship. They planted poppies on the island and had a great harvest. From then on, people called the island Poppy Island.

The sun rises from the sea. On the horizon, rose-colored morning glow leaks out from the gaps in the clouds. The sea is calm and calm.

Han Bingyu's face was pale and he was still groggy. Hualong and Zhou Xingxing helped him take off his shirt. The bullet penetrated his arm, and the wound exposed the bones, which was shocking. Han Bingyu who took off his shirt looked fatter and was missing on the desert island.

Without enough medical treatment, the wound has become infected and suppurated. In a few days, this fat man will become a dead fat man.

They haven't eaten all day.

The next day, they built the house.

On the third day, they ate the house.

The so-called house is just a hole dug on the soil slope, with a few pieces of kelp draped over it. The island is very cold at night, and the wind blows all night, and it is very hot during the day, making people who are exposed to the sun feel dizzy. The kelp is a painting

Dragon picked it up on the beach. The waves washed a bunch of kelp onto the beach, and Hualong picked it up. He originally wanted to use it as a shade to block the sun and wind, but they were hungry and thirsty, and filling their stomachs was an urgent problem.

What does it feel like to be hungry?

Some elderly people still feel fear when they recall the past. An old man once told how he ate a broom. After three years of natural disasters, a production team leader planted potatoes.

After a good harvest, he was frightened by hunger. He boiled the potatoes, mashed them into puree, and built a wall with mashed potatoes in his yard. When the famine came again, he could eat the wall to survive.

Hua Long said: "I can swallow a cow now. If someone invites me to dinner, I will eat today's meal, yesterday's meal, and the meal from the night before yesterday."

"It tastes like beef jerky, very chewy." Zhou Xingxing tore off a piece of kelp and signaled Han Bingyu if he wanted to try it.

Han Bingyu shook his head, and after a long time, he said one word: "Water!"

People who have lost excessive blood must replenish water. The taste of kelp is salty, and eating too much will make you feel thirsty.

Zhou Xingxing finished eating a piece of kelp and carefully observed the roots of the kelp, trying to find something on it. The root system is thick and well-developed, which shows that the kelp is in the mature stage. The waves can wash the kelp onto the beach, which shows that there is a large amount of kelp growing in the nearby sea area.

, this also solved the problem of eating. He asked Hualong to go to the surrounding beaches to have a look. After a while, Hualong came back, and as expected, he brought back another ball of kelp.

Zhou Xingxing found a pit, spread kelp around the pit and packed it with rocks to prevent it from being blown away by the wind at night.

Hua Long asked: "What are you doing?"

Zhou Xingxing replied: "There will be water tomorrow."

At night, the moisture and fog on the sea will condense into water droplets, and the water droplets will flow along the kelp into the pits, accumulating into more. The next day, Hualong and Zhou Xingxing went to see it, and they couldn't help but be disappointed. There was indeed water.

, but there was only a little bit. They had to drink it before the sun rose, otherwise they would be dried by the sun. Zhou Xingxing and Hualong gave the only little bit of water to Han Bingyu. Han Bingyu was not polite, and they took two sips.

After drinking it all, Zhou Xingxing and Hualong could only swallow their saliva.

Zhou Xingxing tried to use clean sand to filter seawater. He dug a pit, filled it with sand, poured seawater into the sand, filtered it layer by layer, and then flowed out from an outlet below the pit. However, after the seawater was filtered by the sand,

, the water quality will not fundamentally change, it will still taste bitter and salty, and cannot be drunk.

Hua Long was restless. Zhou Xingxing sat on the beach and meditated. Their lips were dry. They had not drank water for three days and there was only some kelp in their stomachs. The beach was very clean, without snails and shells. Zhou Xingxing stood up and sighed.

The sea disappointed him. He turned his attention to the desert island. The terrain of the desert island was flat, and there were some dried kelp in some depressions, which were no longer edible. When the kelp matured, its roots broke away from the reef, washed up on the beach by the sea, and dried by the sun.

And it was blown into the depression by the wind.

Zhou Xingxing shouted in surprise: "There is water!"

Hualong ran over: "Where is it?"

Zhou Xingxing pointed to the sea.

Hualong said: "Fuck!"

Zhou Xingxing squatted down and gathered the soil in front of him into a pile with his hands. He asked Hualong.

"How do you kill a man with this pile of dirt?"

"Bend his eyes with dirt, and then..."

Zhou Xingxing laughed and said: "This pile of soil is also a murder weapon. It only needs water and fire to turn it into a brick."

Hualong said: "Yes."

Zhou Xingxing said: "In addition to bricks, this pile of soil can also be turned into other things."

Hualong said: "What?"

Zhou Xingxing replied: "Pot!"

Hua Long nodded and asked again: "If there is no water, what's the use of a pot?"

Zhou Xingxing said: "If you have a pot, you will also have water."

We all did a physics experiment in middle school. Fold a piece of paper into the shape of a boat. Put water in the paper boat, light a candle, and burn it at the bottom of the paper boat. The paper boat will not burn, but the water in the paper boat will.

boil.

Suppose that in ancient times, there were two apes living in a cave. One could use water and the other could use fire. If they were a male and a female, they might mate. Their children would grow up and know how to use stones, soil, and branches.

And so simple tools, children's children grew up - a vessel appeared. Between the Stone Age and the Bronze Age some bowls, clay pots and basins appeared.

Zhou Xingxing makes a casserole!

He sifted the soil with a sock and mixed in fine sand. The sand will form round crystals after high temperature, which makes the surface of the casserole round, able to withstand high temperatures and stronger. He made the clay with water and mud, dried it, and made it on the slope.

I built a simple cave dwelling and after high temperature, a casserole was successfully fired.

We have to say that this casserole looks ugly, like a big inkstone.

It is also worth mentioning that when Hualong drilled wood to make fire and tried to light the pile of dried kelp, Han Bingyu threw a lighter at his feet. Han Bingyu smoked, so he carried a lighter with him.

Zhou Xingxing used the same method to bake a pot lid.

After everything was done, Hualong asked: "Where is the water?"

Zhou Xingxing said: "Wait and see!"

He added seawater to the pot and put a fire underneath. After a while, the seawater boiled and evaporated into steam. The salt remained at the bottom of the pot. The steam condensed into distilled water. The water droplets continued to drip out along the gaps reserved in the pot lid. This is

It is fresh water. The principle of distillation is very simple. Island countries such as Singapore and Nauru also use this desalination technology.

They made a simple reservoir out of stone slabs.

Hua Long said happily: "I'll treat you two to seaweed soup. I'm pretty good at it."

Zhou Xingxing said: "In the evening, we eat steamed crabs!"

Hua Long said: "There are no crabs."

Zhou Xingxing said: "Yes."

Hua Long said: "Why didn't I see it?"

Zhou Xingxing said: "There are crab footprints on the beach. Go take a look when the tide goes out."

When the tide went out in the evening, Hualong indeed caught some crabs on the beach, as well as lively shrimps and fish. The three of them had a hearty meal, and the ice conditions seemed to have improved. Distilling fresh water requires a lot of fuel.

Soon, the dried kelp on the island was burned out. Hualong went to salvage kelp every day. He swam from one reef to another. There was a large amount of kelp growing around each reef. Kelp was a shallow sea plant. Hualong did not

No matter how good your diving skills are, you can catch a lot, which can be used as fuel after being exposed to the sun on the beach.

Once the sun rose, Zhou Xingxing drew a line on the stone. Time passed quickly. They had been trapped on the island for seven days. That afternoon, the three of them were chatting, and Han Bingyu pointed to the horizon and suddenly said: "Quickly

look!"

The three of them stood up and couldn't help but stare blankly.

Dark clouds rolled in from the sky, and the sea surface was surprisingly quiet. Suddenly, strong winds blew up, and the sky was suddenly clouded. Many bubbles emerged from the calm sea level. The dark clouds became lower and lower, and a large bubble rose. After it burst, a bubble appeared on the sea surface.

A huge whirlpool. A thin black cloud column stretched downward from the dark clouds. The drooping funnel-shaped cloud column at the bottom gradually connected with the whirlpool. There was a "bang" on the water surface, and the seawater began to rotate rapidly, gradually forming a water column reaching into the sky.

Connected with the black clouds.

Hualong exclaimed: "Seaspout!"

They have never seen such a spectacular and terrifying scene. People seem too small in front of nature.

Zhou Xingxing shouted loudly: "There is another one over there!"

Another seaspout appeared on the horizon, moving slowly from the southeast. Its upper end was connected with the thundercloud, and its lower end extended directly to the sea. Soon, two seaspouts slowly approached, and the huge energy caused the clouds to spin, and the rotation of the clouds also

It drove the rotation of the air. The seaspout turned faster and faster. In an instant, the two seaspouts merged into one, and a huge seaspout appeared, spinning and flying with a fierce momentum. The surrounding clouds released lightning, and the roots of the seaspout were all around.

The water splashing like snakes is thrilling and very spectacular.

A tornado is a powerful storm associated with low air pressure and rotating wind directions. When the air at the surface and sea surface is heated and columns of air descend from the upper parts of the cumulonimbus storm, the signs of tornado development become very obvious - air

The low-pressure area begins to rotate violently.

Tornadoes at sea can cause seaspouts, and fish and shrimps in the water, and even stranded sunken ships, will be swept into the air. A jellyfish is thrown out among the waves, and its skirt opens in the sky. The eyes of a flying bird are also at this time.

Memories of a fish intruding. Coastal residents sometimes see strange sights. After a seaspout passes, fish fall from the sky and land in their yards.

Some tornadoes only last a few seconds, while others last for more than an hour.
