Early the next morning, Naoto Yoshihara stepped into the rainforest again with Nana Hoshino, and suddenly Nana Hoshino felt a primitive and mysterious aura rushing to her face.

The road in the rainforest is not as difficult as expected, and the layers of fallen leaves are thick and soft lichens, which form the lowest surface environment of the rainforest - the soil in the rainforest is not fertile, and the plate-like roots of the large trees will suck all the nutrients away, and even if there is some leftover, lichens, associated vines, and tropical evergreen shrubs will quickly turn it into a part of itself.

The essence of everything in the rainforest is the trees, whether they are large trees in the upper circle or small trees in the second layer, or associated orchids, bromeliads, or ferns at the bottom - if you cut down the rainforest, you will only get a barren land, and the chance of desertification is very high, and it will not become the super fertile arable land that most people imagine.

Nana Hoshino followed Naoto Yoshiwara in to find something that could be used as material for the raft - she insisted on coming, fearing that Naoto Yoshiwara would cut the wrong tree in vain. But she was very happy, and kept showing off all the way, pointing out various plants to Naoto Yoshiwara and telling him their names, and rummaging around with a walking stick, looking for rare plants, as if a child had entered an adventure park.

For her, as long as Naoto Yoshiwara is around, she doesn't have to think about safety, and it's really like an outing.

Her joy lasted until she triumphantly knocked on a tree and said it was a big cocoa, which angered one of the natives of the tree when a snake suddenly sprang out and scared her half to death.

After searching for a long time, I finally found a medium-sized evergreen tree. Nana Hoshino circled around twice and affirmed, "That's it, that's right!"

Naoto Yoshiwara also went up to take a closer look, and found that the surface of the tree was smooth and light gray, with a straight trunk and a wide broad-leaved canopy, about one and a half meters in diameter...... If you just look at the trunk, it looks like white pine or basswood.

He patted the tree and asked, "At least seven of these trees?"

Nana Hoshino nodded and said: "Yes, this is South American balsa wood, which belongs to the genus Balsa of the Kapok family, one of the fastest-growing tree species in the world, which can grow to a height of five or six meters in a year, and usually reaches more than fifteen meters in ten years." Due to the rapid renewal of cells and tissues in its body, all parts of the plant are unusually soft and flexible...... In parlance you can understand, it's twice as light as a cork in red wine for its size - you don't look at how tall and thick it is now, you can carry it by yourself, it's too light. ”

Naoto Yoshiwara was full of curiosity, pressed the trunk hard, found that it was really soft, and said with a smile: "There are still such trees in the world, I really didn't expect ......"

He had a feeling that his eyes had been opened, and sure enough, the world was so big that there were no surprises.

Nana Hoshino was a little proud, and was very satisfied with the attitude he showed him, which was a recognition of what she had learned, and happily added: "This is a very good economic tree species, with fast timber growth, low thermal conductivity, heat insulation and sound insulation, and it is a pity that it is mostly used in the aerospace industry in modern times, and it is a pity that we use it to make rafts! But it doesn't matter, this kind of tree grows very fast, people used them to make a large number of sailing rafts two thousand years ago, and it is still not extinct, it should be no problem." ”

Naoto Yoshihara doesn't care about this, even if there is only one root left on the earth, he will cut it directly, he is not an environmentalist at all, he is the kind of guy who eats endangered animals even if he is hungry.

He looked around and said, "I'll just look for the rest myself, and I'll send you back first." "It's not safe in the rainforest after all, he reacts quickly and is not afraid of being plotted, but it's a little difficult to protect Nana Hoshino again.

Nana Hoshino has no opinion, Naoto Yoshihara is obviously moving very slowly with her, and she also has work to do, just advised: "Balsa is a plant, as long as you find a tree that should be a population in the vicinity, you just need to search this area." Also, look for iron willow wood, bamboo, we also need those materials. ”

"I see!" Naoto Yoshiwara took her back the way she came, and then went back to destroying nature.

Balsa is really soft, and Naoto Yoshiwara can easily deal with it with very primitive tools, stone axes and machetes, but what about this tree? Although it is easy to cut, it feels extremely bad.

When the axe goes down, it will "squeak" and drip water, which seems to be very painful, and it is full of reverberation force like a cut on plastic foam, which is extremely uncomfortable, and at the same time, rubbing with the axe will also make a scratching sound like fingernails scratching glass, which is very infiltrating.

It feels like a ghost tree.

It took a little time for Naoto Yoshiwara to cut down a tree, and by simply removing the crown of the tree to become a large, straight log, and then one could easily carry it out, if it weren't for the complicated environment in the rainforest, it would have to be reversed along the way, or if it was necessary to force the way open, which was really not a tiring job.

Naoto Yoshihara was cutting wood in the rainforest, and Hoshino was not idle outside—she was boiling seawater in a pot while preparing a rudimentary set of purification equipment, ready to get some salt to eat, and while she waited for it to boil, she took a machete to chop rattan on the periphery of the rainforest, and then dragged it back to peel and weave rope.

She was smart, focused, and able to endure hardships—she had almost all the qualities that opened the door to success—and she sat there, using her hands and feet, sometimes biting and tearing with her teeth, sometimes thinking carefully about the structure of the force, even if her little hands were occasionally cut by rattan, she did not frown, and just concentrated on completing her work.

For a whole day, the two of them were busy with a clear division of labor, and when Ruri Nishikujo woke up in the afternoon in a daze and hungry, he found that the scene around him had changed again - it had become a small construction site.

Thick logs stacked together, filled with a rich and strange smell of air, killed snakes, birds, and Chinese tapirs, pots boiling seawater and rattan skins, a pile of plastic bottles with sand and gravel strung together to form a filter, and rattan trapped.

The long sleep made her feel that things were unpredictable, and looking at all this in front of her was even more inexplicable, and then looked at the seaside not far away, and saw that Nana Hoshino was standing on a huge stone and commanding, dragging a messy rattan skin in her hand, and shouting a few times from time to time in her small mouth, while Naoto Yoshiwara was sweating profusely and was rolling a large stone from the beach to the shallow sea with a lever......

She couldn't help but scream softly "Hoshino-chan" in confusion, and Nana Hoshino immediately looked back, and when she saw that she woke up, she immediately dragged a large cane skin and ran back, and asked later: "Nishikujo...... Sister Nishikujo, are you hungry? We'll be ready to eat when we're done with this - he hit a 'big lady' and said it was delicious, and we'll bake it later!"

"Miss" refers to the Chinese tapir, an omnivorous animal, somewhat similar to badgers.

South America lacks large predatory animals, and the inconspicuous tapir is considered a large animal here, and this species walks and twists, and is stupid, giving people the feeling of not knowing the world, so it was nicknamed "Miss Big" by the locals. Naoto Yoshiwara met this one even more stupidly, as if he had never seen a human before, and even ran to challenge him when he was cutting down trees, trying to drive him out of the territory, and of course it turned out to be the food for dinner delivered to his door.

This animal contains a lot of oil, and in addition to eating it, Naoto Yoshiwara also intends to refine it into oil.

Nishikujo Ruri didn't care about what to eat, but was overjoyed by this sister's call. She smiled softly: "Don't worry, what are you busy with?"

Nana Hoshino can be used for both distractions, and she didn't delay her words as she deftly knitted the complex rattan bark together with her fingers, and replied casually: "We're going to build a small dock by the sea, it's very simple, just circle a piece of seawater, and it will be done in about an hour." ”

Nishikujo Ruri looked at Naoto Yoshiwara's sweaty figure in the sunset, and asked uncertainly, "Dockyard?"

"It's about building a raft and following the trade winds and currents to an island at the bottom of Polynesia. After Nana Hoshino explained, she looked at Ruri Nishikujo's surprised expression and said, "You don't need to go with us, if you feel dangerous, you can stay here!" If we can reach our destination, we will find someone to save you as quickly as possible, Sister Nishikujo, you don't have to worry about anything." ”

"Why take the risk, can't we wait for rescue?" Nishikujo Ruri didn't understand everything, she was really wronged, and she was inexplicably involved in this mess.

Nana Hoshino said regretfully: "I can't do it with him." "She likes this island a lot, if it weren't for the fear of her mother chasing her, she would have wanted to play with Naoto Yoshiwara here for a while.

Nishikujo Ruriken's eyebrows raised, still full of doubts but she didn't say anything, and Nana Hoshino patted her hand again and went back to continue her work.

Nishikujo Ruri is not the type to wait for dinner, she sat there and thought for a while before tearing open her sleeping bag and standing up, gently pressing her shoulder, feeling that there was still a faint pain, but she still ran to the ingredients, wanting to do something.

It's just that......

She is from the "True ~ Miss" background, she has never cooked since she was so old, and she is helpless against this South American animal-type "Miss", but fortunately, Naoto Yoshiwara finally came back, peeled and dismembered the ingredients, and then roasted the two hind legs for her to watch the fire.

After hastily having dinner, they didn't choose to rest - Naoto Yoshihara and Nana Hoshino are both people full of action, as long as the goal is confirmed, people like them will go all out - Nana Hoshino uses the light of the fire to persistently weave the rope, while Ruri Nishikujo can't use one hand, let alone do dexterous work, so she can only use a knife next to her to split bamboo with one hand to make bamboo chips.

Naoto Yoshiwara took a torch to arrange the wood, peeled the trunk, sharpened the top and tail, and cut down the branches and divided them according to their size and length......

When the three of them were tired, they slept hastily, and continued to dry in the drizzle the next day!

Naoto Yoshiwara briefly lined up the balsa wood in the shallow sea that was circled, and asked Nana Hoshino, who was standing on the big rock, "Is that so?"

A thick log more than 10 meters long and one and a half meters in diameter is used as the central axis, one on each side is more than nine meters long and slightly smaller in diameter, and on both sides are two logs of seven and a half meters in diameter and slightly more than one meter in diameter. These seven logs floated in the sea, barely forming a fat "Shen" shape.

Nana Hoshino looked at it carefully for a while, covered her head and resisted the drizzle and confirmed, "Yes, that's it! Then tie it up with a rope along the groove carved in advance, and the base will do!"

Naoto Yoshihara waved her hand to signal that she could get out of the way and take shelter from the rain, while she stood knee-deep in the water and began to fiddle with the logs—they were really light, they weren't floating on the sea, they were lying on the sea, and there was no waterline at all.

Nana Hoshino looked up at the drizzle and quickly fled back to the shed, which was barely dry. Nishikujo Ruri was laboriously cutting the roots of the iron willow tree, and from time to time she stretched out her thin trunk into the fire and burned it, trying to make it as straight as possible.

This thing is not much softer than iron, and in addition to making masts, I am also going to make harpoons and other utensils.

Nana Hoshino wiped the rain from her little face, sat down and continued to weave ropes, according to her plan, this raft will probably use more than 300 ropes of different lengths, and the workload is still very large.

Naoto Yoshiwara tossed until noon to tie the seven logs together, and he tried to climb up - it felt like he was standing on land. He called Nana Hoshino again and asked the overseer to confirm that there was nothing wrong with the base.

Nana Hoshino jumped from the stone onto the raft, looked around, nodded in satisfaction, and said, "It should be like this!"

"Should it?" said Naoto Yoshihara, who felt a pain in his head. Isn't there a standard for this thing? The book you read is not reliable!

Nana Hoshino shook her hand embarrassedly: "I didn't write much detail in the book, that's probably it!" After speaking, she squatted down and looked at the rattan rope carefully, "Is it tied strongly?"

She is not worried about the rattan rope itself, she has tested the strength, and it does not lose to modern industrial products, but she is worried about the strapping technique of Naoto Yoshiwara, and Naoto Yoshiwara is worried about the opposite of her, saying: "It's all a sailor's dead knot, and it will only get tighter and tighter." It's impossible to open the knot, that is, your rope is unreliable, will it be soaked halfway? ”

Nana Hoshino said confidently: "No, this rattan skin doesn't have a draft, it won't be soaked, that's what big-eared people use, no problem!" She then paced small steps on the raft and continued to guide the next step, "Insert the transverse keel board here, here, here, and here, and then you can lay the crosswood, and finally build a small house in the middle, install a standing spinnaker in front of the house, and install a directional spinnaker in the back of the house." ”

Naoto Yoshiwara followed her to confirm the position and asked, "How do you install it? Why do you insert the transverse keel plate? It takes a lot of time to make that thing, how thick does it have to be made, how deep does it have to enter the water? How thick does the crossbar have to be, what style does the house have to have, and what material do you have to use for the sail boom?"

He didn't care about it, he hadn't built this kind of raft before—he had the impression that rafts were all used to drift wood, and the logs were bundled together, and the requirements were not as high as they are now!

Nana Hoshino raised her eyebrows and pondered for a while, and said softly, "That's all there is written in the book......"

Naoto Yoshiwara was puzzled and asked, "What do you mean by that?"

Nana Hoshino bowed her head and said: "It means that it depends on you next! That's probably it, you can look at the details, I believe you!"

Naoto Yoshihara wanted to kick her into the sea...... I don't even believe in the fuck, why do you believe me?

He was speechless for a while, and then drove the guy who could only come up with ideas but couldn't stand up to the farts back to avoid the rain, and by the way, he continued to weave the rope, and spun around on the raft. Not to mention, this thing has an area of more than 70 square meters floating on the sea, which can still give people a sense of security...... He studied it for a while, and then took his knife and ran to the wood on the shore.

It took him two hours to cut four planks and put them under the raft logs, and then it took him more than half an hour to figure out what it was for—not the slightest surprise, just to prevent the sides of the raft from being too stressed, and to help the raft keep its head and tail and keep it on the waves.

It's something that improves stability and increases the impact area of the waves - no wonder you have to wear it horizontally, it turns out that it is not a diversion.

He adjusted the wooden planks according to different water depths for a while, and felt that half a meter of depth was appropriate, so he dug through the logs and fixed the keel boards and logs at 90 degrees with wedges, and then began to lay the crossbeams, that is, the "decks", and at the same time secretly praised the ancients for their ingenuity, and if he wanted to replace them, he would not have thought of this thing, in case he did not have this keel board and rushed into the ocean, and it turned out that the raft turned around from time to time on the surface of the sea, which was funny - even if it could still float to its destination, it kept turning and drifting over...... The picture was too beautiful to think.

The progress of the raft was faster than Yoshihara had imagined, after all, it was the level of technology before the fifth century AD, and with sufficient materials and advanced tools, he quickly laid the crosswoods, and then wedged the raft into a triangular shape of three sturdy iron willow wood as masts, and made the sail booms from thin bamboo.

The living quarters on the raft are also made of bamboo and balsa wood (which by the way serves as spare materials for repairing the raft), mixed with some yellow, yellow, green and green banana leaves and coconut leaves, which looks a little elegant when finished.

Nana Hoshino came to bring him a rope, and by the way, she brought a small sail made of a sleeping bag, and looked at the raft that was beginning to take shape and said happily, "You are very fast!"

Naoto Yoshiwara sighed and said, "It's not difficult, I just don't know how long it will take to fall apart!"

Nana Hoshino is full of confidence: "It doesn't matter if the shelf falls apart, let's bring more rope to the sea and reinforce it all the way, as long as the base doesn't fall apart, we will always reach our destination." ”

As she spoke, she wandered around the raft with great interest—it was bigger than her house—and finally ran to Naoto Yoshihara, where she saw him holding a long stroke, and then looked at the hole in the end of the raft, and wondered, "What is this for?

Naoto Yoshihara glanced at it and said casually: "That's your toilet, and the toilet hasn't been set up yet." After he finished speaking, he couldn't help laughing, "You can let go of your belly and eat, you can't block this toilet." ”

Even if Nana Hoshino was an alien, he didn't believe that she could pull out the super big poop that blocked the Pacific Ocean.

This toilet is reliable!

Nana Hoshino's face darkened, that incident was a lifelong shame for her, and she didn't like to be mentioned by him, but it's not good to be too familiar with people, and they all know each other's shame, and sometimes they can make another one angry half to death when they say it casually.

She twisted her body unhappily, wondering if she could push Naoto Yoshihara into the sea.

Nishikujo Ruri also braved the drizzle to take a closer look, and even jumped lightly on the raft. Naoto Yoshiwara glanced at her and said with concern, "Pay attention to the wound." ”

It was still raining, and he was a little worried about the infection of the wound of the older girl.

Nishikujo Ruri said lightly: "It's okay, it's already starting to scar." "She is in excellent physical condition, although she has a hole in her shoulder, she has started to be energetic again after a little rest for three days, and she is used to leading the development of affairs, and does not like to sit on the sidelines and watch or just do chores.

She took a cursory look at the raft and asked, "Shall we take this thing to the vicinity of Oceania?"

Nana Hoshino was surprised: "We?Sister Nishikujo wants to go with us?" She also thought that Ruri Nishikujo would choose to stay, and she was not afraid of being caught, it seemed that waiting for rescue was a better choice.

Nishikujo Ruri looked back at the island, nodded silently and said, "This raft looks pretty good, it's quite safe, and if I stay on this island alone, it may kill me, so it's better to stay with you." ”

She was a big city girl, and she felt that she might not be able to live Robinson's life.

Yoshiwara Naoto is a little embarrassed, although this girl said that she had to come with her, but after all, she was the first to ask her for help, and now she is stranded on an uninhabited island, which is a little ashamed!

So he smiled with some apologies: "Then let's go together, I will do my best to ensure your safety and do my best to send you back to Dongying." ”

Nishikujo Ruri glanced at him lightly, lowered her eyelids, and her eyelashes trembled lightly and did not make a sound.

In the next few days, the three of them began to make various preparations for the voyage.

Nishikujo Ruri observed Naoto Yoshiwara and found that this guy is actually very delicate, his hands-on ability is super strong, and his survival ability is the best of the best - everything he needs to live on the island is done by this guy, hunting in and out of the rainforest, jumping into the sea to catch fish, drawing animal tendons to make bows and shoot birds, picking edible fruits and fungi, it is almost like growing up on this island since childhood.

She admired it because she couldn't. She was a little afraid to go into the rainforest, always feeling that there were murderous intentions hidden everywhere inside, and from time to time there would be spiders the size of fists, or suddenly colorful poisonous snakes and poisonous frogs would jump.

But in the case of Naoto Yoshiwara, the spider with a big fist became his snack, the snake became a grilled snake skewer, and he even got back a large string of large gourds as water storage utensils.

In this environment, Nishikujo Ruri naturally began to obey the command of Naoto Yoshihara, and was willing. This is a very rare thing, there are few people who can be put in her eyes, and Naoto Yoshiwara is the third man she admires when she grows up - the first is her grandfather, and the second is her father.

Naoto Yoshihara didn't pay much attention to Nishikujo Ruri, who watched his gaze gradually change, and he was busy trying to stock up on food and water. I don't know how long it will take to drift in the sea, and Nana Hoshino confidently said that it will be enough for about a month, but he can't believe it!

So the animals in the island's rainforest fell into bad luck.

South America is home to few large predators, and the island is not well located and unexploited, and the animals that have lived on the island for generations have never seen a ferocious predator.

Naoto Yoshihara wanders around the rainforest like a cold-blooded and dark leopard, and any animal he thinks is edible will not escape the poison - he constantly transports all kinds of animal carcasses out of the rainforest, killing them with amazing efficiency, and Nishikujo Ruri cooperates with him tacitly, and immediately turns into a cold-blooded female butcher, skinning and cramping these animals into dried meat and bacon.

When the food was basically enough, Naoto Yoshiwara turned his head to store the water. This was originally a big problem in Nishikujo Ruri, but Naoto Yoshiwara cut a large number of bamboos back, drilled through the bamboo joints, filled them with water, and sealed the small openings with resin, and a "water bamboo" full of clear water was made.

The gourd was treated in the same way, the seeds were taken out, and then water was poured into it, and it was still sealed with resin.

In the end, these water bamboo and water hyacinth were transported onto a raft by Nana Hoshino, and tied around the bamboo house again. According to Hoshino Nana's calculations, if the three of them didn't take this water for bathing, it would be more than enough to drink for a hundred days.

At the same time, Hoshino Nana completed the great business of boiling salt, making two large bags of coarse salt for later consumption.

She perfected the raft by fitting a water divider on the head of the raft, carefully calculating the weight of the supplies on the raft to keep it stable and tying everything up carefully, transporting a large number of long-lasting fruits, such as coconuts, and even assembling a hand-cranked generator from the wreckage of an airplane to heat the iron plates with electric current so that cooked food could be eaten during the voyage.

By the time everything was ready, five days had passed, and the raft had become a big, colorful and bloated one, but the draft was still shallow, and even the deck was dry under the fierce rays of the sun.

Naoto Yoshihara boarded the raft with Nana Hoshino and Ruri Nishikujo, and Nana Hoshino stood at the bow with an open coconut and said solemnly, "Our voyage is about to begin, and according to tradition, we named the ship......

She was fairer, asking for the opinions of the other two, "I suggested calling it 'Spirit,' what do you think?"

She felt that their actions were full of fearless courage, and the name could be used as the beginning of a legend.

Naoto Yoshihara was pulling the sail and preparing to hoist the spinnaker, and scolded with a smile: "Courage? We are all crazy enough to cross the Pacific Ocean on a raft, do we lack courage? It's called 'Luck'!"

This thing loves to engage in these formalisms.

Nana Hoshino lowered her eyebrows, turned to Ruri Nishikujo unhappily, intending to defeat one vote with two votes to make the name of the ship pass, and asked, "Sister Nishikujo, what do you think?"

Nishikujo Ruri smiled softly and said, "Hoshino-chan, we really need to pray for good luck, I think the 'luck number' is more suitable, and it is very auspicious according to the homonym of Huaxia!"

Nana Hoshino lifted a rock and shot herself in the foot, but after thinking about it, she thought it would work, so she threw the coconut at the head of the raft with all her might—smashing champagne in imitation of the launching ceremony of a new ship—and shouted, "Luck set sail!"

There was a crisp "click", and the coconut flew into the sea with a bang. Naoto Yoshihara raised his half-sail and came over to take a look, and found that the front water divider had collapsed into a gap.

He was speechless for a while, and after a while, he said, "This doesn't seem to be a good sign!"

The new ship was crippled before it left the dock, isn't it?

Nana Hoshino flattened her mouth and said depressedly, "The coconut is too hard!" With her words, the sails on the raft were already bulging, and she pushed the raft against the big rock in front of the top. She hurriedly changed the topic and pushed Naoto Yoshiwara into the water with her small hands, "We're leaving, go and move the stone away!"

Naoto Yoshiwara jumped into the water and overturned two stones in the makeshift dock with a stick, while Ruri Nishikujo held it up with a bamboo pole and sailed the raft away from the island with the force of the wind.

Gradually, the southward trade winds sailed towards the blank sea with the "Luck", and the three of them stood at the end of the raft, watching the island slowly shrink, and finally disappeared into the mist.
