Lu Wuyai suddenly frowned: "You mean you want to drink plain water? Dong Bingling's current condition is caused by drinking water directly from the stream."

"Okay, that's just my guess. After all, water sources in the wild are more or less unclean."

“But we don’t have a container to boil water.” Yu Yuxia pouted, and Qin Feiming was stunned by her beautiful appearance.

In fact, the lack of containers for boiling water has always been a major problem.

We used to have coconut shells, which we could use, but now we don't even have coconut shells anymore.

Ma Fei's notes did indeed contain a method for making pottery jars, but he couldn't find the clay at the moment.

Qin Feiming thought for a moment and said, "Let's go find some bamboo. In fact, we can use bamboo to boil water, and it's much more convenient than coconut shells."

Upon hearing this, Yu Yuxin rolled her eyes: "Big brother, do you think there will be bamboo on this deserted island? If there is bamboo, I think there will be giant pandas."

However, Lu Wuyai thought that since the deserted island was so big, there might actually be bamboo there.

“Dong Bingling and Qin Feiming stay behind; the rest of us will go find them,” Lu Wuyai said.

Anyway, it's free time, and if you go for a walk, you might get something unexpected.

As for why Gu Yuxin and Qin Feiming were left behind, one was a very nervous woman, and the other had a leg injury and was too slow to move.

Before setting off, Lu Wuyai instructed everyone to protect their necks and ankles. No matter how hot it was, there should be no gaps between them.

The last experience with the leeches still terrified Lu Wuyai. If Yu Yuxin hadn't insisted on saving him, he would have been a skeleton long ago.

For this, Lu Wuyai was grateful to Yu Xia.

After leaving the rocky mountain, everyone quickly determined their direction and headed towards the forest.

It was this forest again, the air was humid. Lu Wuyai watched carefully, afraid of being attacked by those leeches again.

It wouldn't have been a problem if he hadn't looked, but when he did, Lu Wuyai noticed that the leaves of the trees nearby, large and small, were covered with withered leeches. One end was sucking on the leaves, while the other end was propped up high. They looked like they wanted to suck blood.

"I, I, we don't want to leave." Song Xiaoyou was pale with fright, mainly due to her trypophobia.

Yu Yuxia and Su Xi were the same, especially Su Xi, who usually seemed aloof, but now his legs were trembling.

"Be careful, try not to touch it."

Lu Wuyai took a breath. The nearby forests were all the same, with lots of water vapor. The deeper you dive, the more leeches you'll find.

The four men covered the exposed parts again to ensure no accidents occurred before they could resume their journey.

After a while, Yu Yuxia couldn't help but say, "Lu Wuyai, if you can't find the bamboo forest this time, I will definitely bite you to death."

Su Xi immediately smiled and said, "I said, where are you going to bite?"

"Isn't that obvious? If you feel comfortable, then go for it. Ye Meng, you slut." Yu Yuxia's face flushed red when she heard the unspeakable difficulty in Su Xi's words.

"I didn't say anything, don't misunderstand." Su Xi grinned, chuckling, and the movement of her chest made Lu Wuyai's eyes widen when he turned around.

"What are you looking at?" Yu Yuxin said unhappily, "Let's go quickly."

Lu Wuyai stuck out his tongue, thinking to himself, "These women are all incredibly skilled drivers."

Two hours later, at noon, a large mountain blocked the road ahead.

Su Xi suggested, "There's a forest nearby. How about we go to the top of the mountain and take a look? If there's a bamboo grove, we should be able to find it quickly."

Upon hearing this, Lu Wuyai began leading the three women toward the mountaintop.

The mountain wasn't very high, but it had a lot of insects.

Besides the leeches we saw earlier, there are also many black-spotted mosquitoes that can bite people through clothing.

"Keep it wide and watch your step."

"Don't swat mosquitoes away with your hands when you're hiking."

"Song Xiaoyou, don't always keep your head down."

Lu Wuyai kept shouting; the pressure of leading the team was immense.

Just now, Su Xi lost his footing and slipped halfway down the mountain. His t-shirt was torn, revealing a large patch of white flesh on his waist and abdomen.

Fortunately, Lu Wuyai sank in time; otherwise, the consequences would have been dire.

After cautiously reaching the summit, Lu Wuyai wiped the sweat from his brow, looked at the three women beside him, and let out a long sigh.

Let's look at each other.

Even though there are no leeches around, you can't be careless. Humans can't feel them sucking blood at all.

Taking advantage of that moment, Lu Wuyai walked forward and cut off several tree branches that were blocking his view.

A cool breeze blew by, refreshing and invigorating.

The view from the mountaintop is incredibly expansive. The endless waves of green stretching out before you are practically a green ocean. It's hard to imagine how large this deserted island is.

"Don't be sad anymore, quickly use the binoculars to see where there's a bamboo forest." Yu Yuxia was already very tired, so she supported her waist and urged her on.

Lu Wuyai took the binoculars off his neck and observed carefully. After a few minutes, he said uncertainly:

"There seems to be a bamboo forest over there, but it's too far. Why don't you go take a look?"

He handed the binoculars to Su Xi. Su Xi took the binoculars and looked at them for a long time. He really couldn't be sure if these blurry plants were a bamboo forest.

"Then rest in place for a while, and take action again after half an hour."

"Why are you resting? Let's hurry up and leave, or it will get dark."

Yu Yuxia kicked Lu Wuyai, and now she urged him to continue on his way.

The suspected bamboo forest was far from the mountain, almost spanning the entire green sea, which was one of the reasons Yu Yuxin was worried.

However, the rest of the journey was much easier than before. There were no mosquitoes or leeches. The only thing that was frightening was the occasional animal droppings on the ground.

In this oasis, most of the plants are tall, with few shrubs and grasses.

“If there were a stream here, it would be a more suitable place for people to live than the rocky mountain,” Lu Jian sighed.

It was past noon when we passed a mound and a few scattered bamboo trees caught our eye.

"Hey, there really is bamboo."

"There's a lot more behind; it really is a bamboo forest."

"Lu Wuyai, hurry up and cut some bamboo. It's getting late. Try to be back before dark."

Before coming, everyone considered that the distance between the bamboo forest and the rocky mountain would be too far, so they made some detailed preparations in advance.

For a time, everyone was extremely busy.

Lu Wuyai took the life bag off his waist, then took out an axe and swung a large bamboo pole.

The fallen bamboo was then pulled apart by three women who used daggers and stones to cut off the branches.

In addition, the bamboo used for boiling water must retain its nodes, which makes it easier to transport and also allows it to hold water.

Ten minutes later, Lu Wuyai had cut down a total of three bamboo stalks. He then cut these three bamboo stalks into dozens of sections, each with nodes at both ends.

Soon, all three life-saving bags were filled with bamboo.

Lu Wuyai checked the time. The sun had already begun to set, and there were still three hours until dark.

So the four of them then carried their life-saving kits and jogged away. They did more exercise that day than they had ever done in any previous day.

When I finally reached the rocky hill, I was so exhausted that I didn't even want to move my fingers.

Qin Feiming's eyes lit up when he saw the three life-saving bags filled with bamboo.

"I really found the bamboo forest."

"Nonsense," Lu Wuyai slumped onto a rock, pointing at the bamboo, and said, "Figure it out yourself. I want to drink some hot water before bed."

Qin Feiming had been idle all day. Now he stood up and, as if by magic, pulled a black rope out of his pocket.

Then, take out a bamboo stick, place it between your legs, and begin rubbing it with the black rope between the two bamboo nodes.

Spiky, spicy, spicy.

It was just an ordinary rope, yet it made a sawing sound.

Lu Wuyai was very curious. When he got closer and saw this scene, he reached out to touch the black rope, but Qin Feiming slapped his hand away.

"Look how stingy you are. You won't lose it if you just touch it."

"I advise you not to be curious. This is a saw, not a rope." As he spoke, Qin Fei understood what he meant.

I'll check.

There's such an awesome rope.

Seeing the sawdust flying everywhere, Lu Wuyai was certain that it was a saw.

"This is also a standard tool for your rescue team," Lu Wuyai asked curiously.

"Yes." Qin Feiming nodded.

Lu Wuyai gave him a deep look. He had searched Ma Fei's body before, but couldn't find such tools...

A few minutes later, a rectangular bamboo board was missing from the middle of the bamboo, and there were two small holes at both ends outside the bamboo node.

Immediately afterwards, Lu Wuyai saw Qin Feiming sharpen two pieces of wood with a knife, the tips of which could be inserted into the small hole.

Thus, a perfect stand was ready, with bamboo in the middle. The missing bamboo plank was just right for pouring water. The flame licked the bottom, and the water bubbled at a visible speed.

Within minutes, the water inside the bamboo joint boiled.

Seeing this, everyone else got excited, as if being able to drink hot water was a story from the last century.

"Give Gu Yuxin a drink first."

Seeing that Gu Yuxin's complexion was still not good, Lu Wuyai let the boiled water cool down for a while before giving it to her to drink.

Turning his head, Lu Wuyai looked at Qin Feiming anxiously.

"Don't even think about it." Qin Feiming sneered and hid the black rope near his body.

Lu Wuyai frowned, but that black rope was really important to them.

Tools are an important part of life on a desert island.

At 7:30 p.m., Yu Yuxia and the others began roasting wolf meat. The rich aroma of the meat made everyone's mouths water, especially Lu Wuyai and Qin Feiming, two grown men who hadn't eaten meat in a long time.

As for Qin Feiming, although he was the one who killed the wolves, he had prepared for a long time before he succeeded.

Wolves aren't so easy to kill. Now that they've eaten them, who knows when the next time will be?

At this dinner, everyone ate half a wolf.

After dinner, Lu Wuyai kept thinking about the black rope, feeling increasingly uneasy. Occasionally, he would see the wolf's head abandoned in the forest, its fangs gleaming coldly.

"If I can't get the black rope, why can't I make one myself?"

In the blink of an eye, Lu Wuyai found Song Xiaoyou and asked her to look through the notebook. He remembered that the contents should involve the making of outdoor tools.

Ma Fei's diary is actually a collection of his outdoor works.

It covered a lot of content. When we first got it, everyone listened to Song Xiaoyou's translation every night. At first, it was simply to relieve the boredom of life.

Lu Wuyai vaguely remembered a simple saw-making process in it.

In fact, Song Xiaoyou quickly found information on how to make a saw. However, some parts of it were difficult to translate and understand for the average person. Fortunately, the key points were marked with pictures and text.

"I'll give it a try, you go to sleep first." Lu Wuyai stood up and walked towards the wolf corpse.

At this point, Song Xiaoyou thought for a moment, then stood up with her notebook in hand.

Half an hour later, Lu Wuyai finally pulled out all the teeth from the two wolves. After carefully counting them, he found there were 80 teeth, but not all of them were suitable for use as materials.

At this moment, Lu Wuyai realized that Song Xiaoyou was following him closely.

"Why aren't you asleep yet? Let me try, maybe it's just a waste of time." Lu Wuyai urged Song Xiaoyou to go to sleep, as he had to keep watch tonight.

"I...I'm not sleepy." Song Xiaoyou shook his head, walked to the side, and based on the contents of his notebook, he actually tried to saw out the entire frame.

Seeing that Song Xiaoyou couldn't resist, Lu Wuyai could only raise his head and look around the campfire, only to find that everyone else was already resting except for the two of them.

"Take your time and observe. I'll try the saw blade. If it doesn't work, your work won't be in vain."

Upon hearing Lu Wuyai speak, Song Xiaoyou nodded.

In the city, saws and saw blades are made of metal, but on the deserted island, Lu Wuyai chose to use wolf fangs instead.

Don't assume that wolf fangs are inferior to saw teeth. When Lu Wuyai actually came into contact with them, he discovered that wolf fangs were just like knives, capable of easily cutting through the skin.

"When I watched TV before, I never thought teeth could be so sharp."

Lu Wuyai licked his lips and used the wolf teeth to make serrations. It was simply perfect.

The saw blade was a bit of a hassle, but Song Xiaoyou had already started binding the saw body, and soon the entire frame was completed with ropes made of twisted tree bark.

On the other hand, Lu Wuyai's progress was a bit slow, mainly because the making of the saw blade required trial and error step by step.

Not long ago, Lu Wuyai chose a piece of wood as long as a saw. He chopped it, cleaned it, and then split it in two with an axe.

He originally planned to place the wolf tooth between two pieces of wood and then secure it with tree rope, but the finished product didn't look very good. The most important problem was securing the wolf tooth.

"If only we had glue."

Lu Wuyai sighed, looked at the saw blade in his hand, and could only use it helplessly.

"Song Xiaoyou lowered her head and thought for a while, then suddenly said, 'I can go get the glue.'"

"What?" Lu Wuyai looked at Song Xiaoyou, seriously doubting whether he had misheard.

"I...I...I can get the glue." Noticing Lu Wuyai's gaze, Song Xiaoyou became a little nervous again.

"Don't joke around, you're casting a spell on me in this desolate wilderness."

Lu Wuyai rolled his eyes, looked at the saw in his hand, and realized it was barely usable.

But Song Xiaoyou suddenly grabbed Lu Wuyai's clothes and pointed to a big pine tree in front of them.

"Resin can be used as glue."

Lu Wuyai was stunned for a moment before he understood: "Resin, how did you make it?"

“I, I, I, let me try. I used to watch the old people in the village collect rosin, and I, I learned a little bit.”

"So fast." Lu Wuyai thought to himself that Song Xiaoyou was indeed a treasure, and she even understood this.

Soon, Lu Wuyai saw Song Xiaoyou pick up an axe and chop off the bark of a pine tree that was waist-high. Then, with the axe blade, she drew a V-shaped symbol from the top left to the bottom right and from the top right to the bottom left, and then drew a diagonal line downwards at the intersection of the numbers.

"This is the oil pipeline, and the rosin can drip down from this direction," Song Xiaoyou explained while tying a bag to the bottom of the oil pipeline.

Seeing this novel scene, Lu Wuyai inexplicably felt that he would definitely succeed.

How long does it take to collect this rosin?

"It depends on the pine trees. If things go quickly, we might be able to buy them tomorrow."

"Tomorrow, I guess. It'll be quick."

Lu Wuyai pondered in his mind, looking at the saw in his hand, feeling both expectant and excited.

That night, Lu Wuyai kept glancing at the pine tree, hoping to get some grease quickly so he could make a saw.

In fact, it wasn't until dusk the next day that he noticed the road was somewhat damp.

By the time it got dark, the bag was covered in rosin.

“I don’t use much, so this should be enough.” Lu Wuyai couldn’t help but ask Song Xiaoyou, as the waiting days were indeed hard to endure.

Many people looked at the campfire, and even Qin Feiming was curious whether Lu Wuyai's saw would succeed.

"That's fine then."

Song Xiaoyou cut a clean piece of wood, dipped it in rosin, and then evenly applied it to each wolf tooth. Finally, he joined the two pieces of wood together and tied the ends tightly with tree rope, and the saw blade was complete.

In fact, even without a saw body, the saw blade can be used alone, and it is quite convenient.

After waiting for a while longer, guessing that the rosin had completely solidified, Lu Wuyai began to conduct experiments.

There are still many bamboos, so Lu Wuyai began to try to cut the bamboo sections open with a saw.

The chirping sounds gradually became more rhythmic.

"It's really done!" Qin Feiming was surprised to find that the bamboo had been cut down and the fangs had just been placed in the wrong place.

Hahaha.

Lu Wuyai laughed excitedly. He hadn't expected that the homemade saw glued together with rosin would work so well.

“In fact, these wolf fangs are too sharp,” Ye Meng said.

Through constant friction with the bamboo, the wolf's teeth seemed to become sharper than before.

Lu Wuyai tried it a few more times and found that this saw was very convenient for cutting bamboo sections. However, because the size of the saw blade did not match the wolf teeth, it was difficult to cut some large trees.

In any case, this homemade saw was a great success.

While the iron was hot, Lu Wuyai used the remaining wolf teeth to make two more saws of different sizes that very night, and coated all the joints of the saw blades with rosin.

By the next day, the rosin had completely solidified.

"It's really good." Lu Wuyai looked at the three saws in his hand and liked them more and more.

"It would be even better if we could get more wolf fangs to help them out."
