It is not accurate to say that it is a gap.

But it's not too much.

It doesn't look like a cave, though.

It is like an anomaly caused by the erosion and weathering of seawater.

Seeing this scene, Lu Yu's eyes lit up, and he hurriedly turned the camera and pointed to the rocks in the distance:

"Brothers, do you see the gap under that rock? Let's go and see, and maybe we'll make an unexpected discovery. ”

As he spoke, he took three steps and made two steps, and hurried over.

Finally.

Come to the front.

The rock is in full view.

A large narrow opening, located at the very bottom.

Lots of space.

The deepest part of the coastline may be twenty or thirty meters.

The inside of the gap is very smooth.

At first glance, you can see that this is the result of years of sea erosion.

In addition, the white salt stain on the surface of the rock is also the best proof of this argument.

After looking outside for a while, Lu Yu went straight to the gap, looked around for a while, and finally came to a conclusion:

"The place is nice, although not a cave, but it is enough shelter from the wind and rain. ”

"You see, this is a classic phenomenon of seawater erosion. The ebb and flow of the tide day after day carves a large narrow space at the bottom of the rock...... To be honest, this is definitely a very good natural camp, you don't need to do much, you just need to hide here, build a fire, and you can get a foothold first. ”

Anyway.

Lu Yu once again shifted his attention to the present and carefully observed the gap.

Immediately after that, he bent down again and slowly moved to the deepest part to check the tide line.

One of the most important aspects of building a shelter along the coast is to observe the tide lines.

Whether it's a sloping house or a natural shelter, always make sure that the place to rest is on the tide line.

Only in this way will the rising and falling waves not disturb you.

Thinking of this, Lu Yu said slowly to the camera:

"Friends, when building a shelter in such a place, you must pay attention to the tide rise and fall line, whether it is adapted to local conditions or do-it-yourself, as long as you live around the beach, you must pay attention to this. ”

"This is especially important because no one wants to be suddenly woken up by the waves at night while sleeping at night. ”

Facing the camera, Lu Yu gestured while talking.

The audience was told about the intertidal zone and how to judge it.

All kinds of professional knowledge, everyone was stunned when they heard it.

Almost all of them were surrounded by Lu Yu.

But I still listened to it with relish.

"The water line at high tide is the ** line, the water line after low tide is called the low tide line, and the intertidal zone is the area between the high tide ** line and the high tide low tide line. ”

"What we have to do is to keep the shelter above the intertidal zone at all times. ”

"The way to determine the intertidal zone is very simple and straightforward, just look at the texture of the beach and stay away from the tide pools, which are the small pools that are scattered above the low tide line, and you can get a general range. ”

Saying that, Lu Yu practiced it.

According to this method, combined with the situation at that time, the tide line was planned, and his shelter was placed in a relatively safe range.

Honestly, it's really good here.

The space is huge though.

But it's very compact.

The rock above is a natural rain shelter, the perfect single-top slope house!

Secondly, the view is also very good.

With your back against the rocks, you can see the general situation of the coast in all directions.

Of course, these are all secondary.

The most important thing is that in front of the shelter, there is actually a small rock.

"This rock can really be regarded as a stroke of genius, it is just right. ”

Looking at the rocks, Lu Yu muttered.

However, the audience doesn't seem to understand this very well!

One by one, they all asked in the barrage:

"Isn't it just a broken stone?"

"yes, Feather God, what's so strange about that?"

"It can't be some valuable gem head, right?"

"Upstairs, your brain is really big, this kind of stone, our house is everywhere, if it is a gem, I will not send it?"

……

In the barrage, everyone has their own opinions and says everything.

Here, Lu Yu didn't continue to sell Guanzi, and directly gave the answer:

"Brothers, this stone, although it is an ordinary stone, is a treasure to me. ”

"The location of the rock, just in front of my shelter, is just the right distance, one more point is far, one point less is close, if you light a bonfire under this rock, it will immediately become a good heat reflective wall!"

Heat-reflective walls?

The audience was a little confused when they heard it, so the screen was full of question marks.

Seeing this, Lu Yu continued to explain:

"Actually, it's easy to understand, we all know that heat is actually a wave, it can be reflected. ”

"Yes, it's that simple. ”

"Without this rock, most of the heat from the campfire would be wasted. But with it, it's different, when the time comes, the heat emitted will pass through the rocks and feed back to my location, avoiding heat loss to the greatest extent. ”

"In this way, at night, as long as the campfire is not extinguished, I will spend the whole night in a more comfortable temperature. ”

Wow!

Hearing Lu Yu say this, the audience suddenly brightened!

“666！”

"Awesome, with a physicist?"

"It seems that I really can't get along without culture these days!"

"Don't reason with me, I just want to watch uncensored live streams!"

“233333333”

……

Soon, after choosing a shelter, Lu Yu was also busy all the time.

Along the bushes along the coast, I touched for a while, and got a lot of palm leaves.

"Although there are heat-reflective walls, the moisture-proof work should not be neglected either. I once said in the live broadcast that moisture prevention work is the most important part of the process of setting up a shelter. ”

"Even if you don't have time to build a shelter, you can't give up on it, because moisture protection is so important. ”

"Especially here, sleeping on the beach is almost the same as seeking death. ”

"The specific heat of sand and gravel is smaller than that of air, during the daytime, when absorbing the radiant heat of the sun, the temperature of the air near the ground of the same mass of sand and gravel is higher, and the heat transfer is transmitted from sand and gravel to the air, and at the same time, because the specific heat of sand and gravel is small, the heat absorption of sand and gravel rises rapidly, so that the air near the ground also heats up rapidly. ”

As he spoke, Lu Yu placed a large handful of palm leaves on the beach of the rock shelter.

While making his own bed in full swing, he explained to the audience the importance of moisture prevention work:

"But once it's night, things change. The surface of the earth radiates heat to the air, and the air convection, the sand and gravel and the cold air near the ground exchange heat, and the sand and gravel form a cooling transfer to the air...... So, at night, the temperature along the coast drops sharply. ”

"At this time, if you are defenseless and sleep on the ground like this, the heat in your body will definitely be lost at an unimaginable speed, and if you are lucky, you may be able to see the sun the next day, and if you are unlucky, you will really sleep......"

This is not unfounded.

The principle that sand is smaller than heat is also known to the audience.

So when I heard it, everyone realized the seriousness of the problem.

At the same time, I finally felt the danger of surviving in the wilderness!

If you're not careful, you may die!

"I wipe, the consequences are so serious?"

"Big brother, what do you think ......?"

"If you're not careful, you'll die?"

"Really!"

"Feather God, I know so much!"

"The anchor is too powerful, right? Do you have an encyclopedia in your head?"

……

has been busy arranging the shelter, and at this time, Lu Yu has no time to talk to the audience.

Right now, the sun is gradually moving westward, and it is estimated that it will not be long before the sun sets.

So, we have to hurry.

Take advantage of the bright day now and hurry up to finish the work at hand.

Then, if you have enough time, you might be able to build a fire before it gets dark.

For now, fire is not necessary.

Even if you can't get it, it doesn't affect anything.

But with fire, it will undoubtedly be more comfortable.

Especially in the capital accumulation phase in the early stages of survival.

Fire.

It can really help a lot.

In addition to giving warmth and grilling food, fire also plays an important role.

That is, it can soothe the restless hearts of the survivors and obtain vital light in the dark night.

Sometimes, perhaps this is the greatest significance of the existence of a campfire.

"Hoo ——!"

After a few busy times.

Lu Yu took a heavy breath.

At this time, the sand of the shelter is no longer monotonous, and is covered with thick palm leaves.

Looking at his masterpiece, Lu Yu didn't talk nonsense, and sat on it for the first time to feel it.

"It looks pretty basic, but there's no doubt that with it, I'll be able to get a good night's sleep tonight. ”

……

Sit where you are.

Lu Yu was resting and chatting with the audience.

At present, the three elements of water, food, and shelter are preliminarily achieved.

With these three things, the next action will not be constrained.

After all, in any case, the basic necessities of survival have been initially established.

In the process, even if there are setbacks, there is room for maneuver.

For Lu Yu, on the first day of the desert island, he was able to have such a start, which was already very smooth.

However, in addition to the needs of survival, there is one biggest problem, which should not be ignored.

That is, mentality.

Because this is not only a place where you can temper people's mentality, but also a place where you can explode your mentality!

No one is in sight.

Companionship with trees.

This is undoubtedly a great challenge for modern people who live in civilized societies all year round.

After resting for a while, Lu Yu slowly stood up from the beach, picked up a few palm leaves, and prepared to go back to the spawn point to retrieve the leftover coconut shells.

They are also very useful.

On the way back, in order not to let the live broadcast room be left out in the cold, Lu Yu was not idle.

Along the beach, along the way, he said:

"The loneliness that comes with this island grows stronger over time. ”

"If you don't have the right mental fitness, you are likely to stay here for a few days, and you will be on the verge of collapse, and when you think about surviving here alone, that anxiety will hit your whole body......"

"People are social animals, if a person is in a closed space for a long time, it will really go crazy, so the key to survival success, in addition to water, food, shelter, these external factors, the most important thing is that you need to have a strong heart. ”

"This is the most indispensable quality for conquering no man's land. ”

If you listen to these words casually, you may not be deeply touched.

But as long as the details will be.

The careful thinking is extremely terrifying, and it will gradually surface!

I won't come into contact with people for two months, and the huge desert island is only myself, this kind of thing, as long as you put yourself in your shoes and think about it, anyone will feel very scary!

"Come on, Feather God!

"It's scary to think about it!"

"A person at home for a day, will have an explosion of mentality, the most important thing is to ...... without worrying about food and clothing"

"I feel like it's too hard to stream!"

"Give me a computer, I can stay at home for two months......"

"Upstairs, I won't give you anything to eat, there's a computer and a fart!"

"Feather, you don't suffer from depression, do you?"

Looking at the barrage, Lu Yu smiled heartily and explained:

"Don't worry, after all, I've been communicating with you all the time, and although I can't see you, text communication is also a kind of communication. As long as you are talking, someone is listening, and some negative emotions can be alleviated to a certain extent. ”

……

Soon, along the beach, all the way back to the spawn point.

At this time, it is getting westerly.

Approximate time.

Probably around three o'clock in the afternoon.

After picking up the few coconuts he had eaten, Lu Yu faced the camera and said slowly:

"Although there is no coconut water, these coconut shells are still very valuable, and if you can collect them, you must collect them as much as possible. After the fire, the coconut meat inside can be roasted and eaten, and I will tell you secretly that it tastes very good. I bet there must have been someone in the live broadcast room who has eaten this delicacy. ”

The words fell.

The entire screen is almost entirely 1111.

Immediately afterwards, Lu Yu continued to explain:

"Coconut meat, also known as endosperm, is not only a great source of carbohydrates, but also contains a lot of protein. ”

"Of course, in addition to these nutrients, there is another secret in coconut meat, and that is coconut oil. ”

"Fresh coconut oil, Polynesian's favorite natural sunscreen, protects against at least 90% of UVB rays, and applying coconut oil to the face can be very effective in preventing sunburn. ”

"As you can see, the ultraviolet rays here are still quite strong, so you must do a good job of sun protection, if you really get sunburned, it will be very troublesome. ”

As he spoke, Lu Yu immediately took the coconut shell in his hand and dismantled it in half along the crack.

Then, stretching out his finger, he buckled a small piece of coconut meat in it and crushed it finely.

Apply to cheeks, neck, arms, and shoulders......

A big man, naked, standing on the beach, applying sunscreen to himself.

This picture still looks a bit out of place.

Although I knew that it was for survival, it inevitably caused the audience to laugh -

"Laughing pee!"

"Feather God, you live so exquisitely!"

"Last time it was mud, this time it's coconut oil!

"Lovely feather god!"

"Ask for the same sunscreen link!"
