Kexin and Maya woke up one after another, everyone has their own tasks today, so they hastily ate the leftover turtle meat from yesterday and start the day's action, Yun Yanuan's task has been completed last night, but he feels that a few people also need a backpack, which can easily carry food, turtle shell cooking pot, and sweet water vine.

So he went to the distance to harvest as much hay as he could, and when he came back, he made four small baskets according to the method of the northern straw chicken coop, the largest of his own, and the three girls were relatively smaller.

The back basket is good to weave, but the strap makes him painstaking, several people have no clothes, the shoulder leaks, if the strap is not soft enough, it is easy to wear out the skin, causing injury, once infected, it is easy to become a bigger trouble.

He carefully smashed the hay with stones to make them as soft as possible, so that it was a harness that, as long as it was wide enough, would not strangle the skin so easily.

After all this, I went to find four straight, forked hardwood poles, each one and a half meters long and short, trimmed and smooth with a saber, which could be used as a crutch for mountaineering, as a weapon to protect oneself when necessary, and as four beams and eight pillars for temporary camping tents.

The most difficult thing to carry should be fresh water, a few people do not have a container that can hold water, directly carry sweet water vine, short distances are OK, long journeys are definitely not possible. There is no solution to this problem, and we can only hope that there are many sweet water vines in this forest, or that we can find a water source.

It is easy to find air-dried sea salt here, and the straw basket he made has a gap, so it is impossible to install sea salt directly, so Diana found a lot of broad leaves, wrapped sea salt, and wrapped it into a small bag with straw rope, which is convenient to use and easier to carry.

There are many kinds of food, but it is difficult to carry them for a long time, Maya and Diana put the shells they found. Conch. Crab. Sea vegetables and some unlucky shallow water marine fish are placed on a flat rock on the shore and dried in the sun, and after the water is drained, these meats can be stored for a longer time, and if the sea vegetables are completely dried, they can be left for a year.

But the speed of drying is too slow, Yun Yanuan even spared no effort to get a lot of firewood on the seaside, and then with the fire, he lit a bonfire next to this rock, the sun is sunning, the majesty of the seaside, plus the moxibustion of the bonfire, these foods will be completely dehydrated in a few hours.

Kexin was still walking around the perimeter of the camp, no one knew what she was doing, she asked twice, she only said that she was confirming the direction, and then she didn't bother anymore, Yun Yanuan saw that she couldn't help, so she ran to the beach and looked for food with Diana Maya.

Although I know the location of the turtle egg, that thing is nutritious and a good health product, but it has a disadvantage, that is, the protein content is too high, even if it is cooked, it cannot be coagulated, and the thin sugar is sugary, and the skin is not strong enough, so it cannot be carried at all, and it is not good if it is cooked.

This made Yun Yanuan give up turtle eggs, and try to focus on shellfish and sea vegetables, these two things are rich in nutrients and can almost supplement more than 90% of the vitamins and energy needed by humans, as for vitamin C, it can only be supplemented by wild vegetables and wild fruits in the forest.

Everything he does now is to prevent him from starving after entering the depths of the island, in case he can't find food, but Yun Yanuan doesn't think it will be like this, when he was in the special training of the army, he was thrown on an isolated island for a month, and he had no supplies, only a knife and a gun.

In that month, he starved for the first ten days, and after that, he had a lot of fish and meat, but at that time there were guns, and it was indeed too convenient to hunt, and he felt that he should make a bow for hunting, but there was no bamboo here, and he did not see a wooden rattan suitable for making bows and arrows, so he could only meet it later.

As long as he has the right wood, he is still confident that he can make a bow that can hunt birds and small animals, and if he has a strong enough cable, he can even make a compound bow that can hunt wild wolves.

There are really too many shells on the seaside, and there are a lot of crabs in the cracks of the rocks, Diana and Maya have lived in the Fijian tribe for many years, and have long learned to hunt in the shallow sea, especially Diana, when she was delivering food, she saw the hardwood pole made by Yunya Nuan, and couldn't help but be interested, so she turned the dagger over the head, and tightly strangled it with the metal hoop carried on the Yunya warm deerskin belt, turned it into a spear, and then took off the grass skirt and straw shoes, and jumped into the shallow sea to insert fish.

Her skills really didn't say, almost every shallow three times into the sea, she would bring a big or small sea fish, Yun Yanuan is a northerner, doesn't like to eat fish, and really doesn't know much about the types of fish, but Maya told him that these fish are edible and not poisonous, which made him feel at ease, after all, poisonous fish are almost concentrated in the Pacific Ocean.

These fresh fish are so precious that they are not comparable to shellfish. Maya threw the fish to death, scaled them off with shells, and baked them on the edge of the rocks closest to the fire, dehydrating them as quickly as possible.

Dried fish is a food that can be left out for a long time, especially marine fish. It was nearly noon, Yun Yanuan directly brought the turtle shell to the beach, got a fresh fish, and began to stew fish soup, but the heart was called to eat, this meal was sweeter than what I ate yesterday, there is fish soup to moisten the stomach, and there is more grilled fish and roasted shells to stimulate the taste buds, indescribably comfortable, but everyone eats a mouth full of black, looking really embarrassed.

Kexin announced to the three of them during the meal that she had found a way to determine the direction temporarily, at least in the forest, she would not lose her way, and as for after leaving the forest, she would have to think of a way again.

Yun Ya Nuan hurriedly asked him what the method was, the dead girl actually sold Guan Zi, not to say directly, until after she was full, Diana continued to fish, Yun Ya Nuan was taken to the woods by Ke Xin, she pointed to the roots of the tree for him to see, Yun Ya Nuan looked at it for a long time, only to see a group of ants moving, so she said: "It's going to rain!" ”

Kexin rolled his eyes at him, pointed at Yun Ya Nuan's nose and scolded the stupid, and then said, you are coming to see this with me, after Yun Ya Nuan followed him, he found that the place where he let him see was a huge bluestone, and he looked around the bluestone carefully for a week, but still didn't find anything, just saw a group of ants moving, so he had to bite the bullet and say:

"The ants on this side are also moving, and it looks like it's really going to rain heavily!"

Ke Xin had an expression that the elm was not open, and the children could not be taught, and pointed at Yun Ya Nuan with his finger, like an ancient teacher, and said with a hand behind his back:

"Look at the direction of these ant burrows, do you find anything?"

Yun Yanuan then woke up, and sure enough, the direction of the holes of the two ant nests was the same, but Xin immediately took him to observe several ant nests nearby, and came to a conclusion that the direction of these ant nests was the same, which also reminded him that the previous instructor had said that the exit of the ant nest is facing the south, which is the habit of animals, and the rising sun has many benefits, just like people like to buy a house facing north and facing south.

However, he still didn't understand why the ant's nest could still maintain the same direction because the island rotated on its own, and there was no fixed direction at all. Kexin answered his doubts, the ants relied on the magnetic field to identify the direction, not the sun, this island rotates by itself, and the earth's magnetic field will definitely not affect the ants here, but because of the rotation of this island, Kexin suspects that this island has its own unique magnetic field, so she uses the ant nest to confirm her judgment and prove that she is correct.

Kexin judged that it may be precisely because of the island's independent magnetic field that satellites cannot observe its existence.

And because of the rotation, the shape of the island should be very likely to be close to a circle, so the source of the magnetic field, nine achievements in the center of the island.

Yun Yanuan believes that the possibility of this theory being true is very high, and even if the dot of the magnetic field is not in the center of the island, a few people will not get lost in the forest anymore with the ant nest, and they can get as close to the interior of the island as possible as much as possible.
