A Misunderstanding caused by drilling for Fire.

"Ah..." Tang Xiaoguo was a little disappointed, but soon got excited again: "If I can't find an emperor crab, finding a big hairy crab is still very good!"

"You found a hairy crab on the beach?" Jiang Yao was very surprised.

Tang Xiaoguo said very positively: "I have found one!"

Ning Shu smiled and said, "Are you sure it was a hairy crab and not a paddle crab?"

Tang Xiaoguo thought for a while: "Aren't all crabs the same!"

Lin Qianqian said, "Of course not, some are sea crabs, some are river crabs!"

Lu Zhe didn't want to discuss whether hairy crabs could be found on the beach. He said, "The problem is, can you walk with your feet?"

"Let me try!"

She tried to curl her little feet and walked two steps like a little penguin: "Look, no problem, right..."

But after just two steps, the sand splashed by the third step accidentally touched the wound, and she screamed again!

"I think you should stay in the camp!"

"No, I want to go!"

Lin Qianqian said, "Let's do this, let's take turns supporting Xiaoguo, and wherever it's fun, let her sit there for a while, okay?"

The girls all raised their hands in agreement!

Jiang Yao blinked playfully and invited, "Little Zhe, why don't you come with us too!"

To be frank, searching for supplies on the beach was indeed a very interesting thing, but Lu Zhe knew that he had more important things to do now!

"No thanks, you guys go have fun. Remember, don't split up, don't go too far from the camp, blow the whistle if you are in danger!"

Jiang Yao pouted in disappointment and exhorted, "Be very careful!"

Tang Xiaoguo pouted, "Yao Yao, come and support me!"

Lu Zhe smiled and made an "OK" gesture with his hand.

Watching the smiling figures of the four girls, Lu Zhe was also in a good mood!

And now, with a simple camp and bottles of water that could sustain life, when thinking rationally, the most urgent thing was to start a fire.

The campfire could not only cook food, but also provide light, warmth and hope.

When encountering rescue teams and fishing boats, burning wet wood and plastic could also generate black smoke to send signals.

The campfire was as important as fresh water for survival.

He felt it was necessary to start a campfire before nightfall.

However, he didn’t smoke and didn’t have a lighter on him either. Even if he did, they weren't allowed on planes!

What were some ways to start a fire in the wild?

Either find flint and start a fire by friction!

Or use the principle of convex lens to focus sunlight to start a fire!

There was also the most commonly used hand drill method!

Oh yes, there was also the battery fire lighting method!

This was the simplest!

But now, the three mobile phones were either out of power or soaked in seawater for too long, the batteries were already dead and could not be used at all.

What about the other methods?

He didn’t know where to find flint, and there was no device like a convex lens either. The only method that met the conditions was hand drill!

And there were several hand drill methods, including drilling directly with hands, the Iroquois piston drill, the bow drill, and the fire plow!

Lu Zhe carefully weighed them in his mind!

Rubbing and drilling directly with hands was definitely not going to work!

That would make his hands full of blisters very soon, and it required a specific kind of strength, otherwise blisters would appear in less than ten minutes!

What about the Iroquois piston drill?

Also not going to work!

That device was quite complicated, requiring drilling holes. Firstly, he didn’t have a drill bit now, and secondly, he didn’t have a knife, so it would be very difficult to complete!

How about the fire plow method?

Also known as the fire saw method.

It was the method Tom Hanks used when he was struggling to survive. The efficiency was a bit low!

To tell the truth, the most suitable fire lighting method for him was using a bow drill!

The method Bear Grylls used most often!

This device was relatively simple to build!

Find a flexible piece of wood and a piece of rope to make a bow, then find a small wooden stick, tie it around with the rope, and press it against a piece of wood!

Pulling the bow back and forth would cause the small wooden stick to spin rapidly!

The efficiency was much higher than rubbing directly with hands!

Yes, use a bow drill!

With the plan in mind, he then started to implement it!

First he found a downwind location to prevent the small flame that had just been ignited from being blown out.

He decided to build the fire starting point under a tree forty meters away from the camp!

After the fire stabilized, he would move it to the camp!

Next was to find suitable branches. This was not difficult. In less than five minutes, he found a 30cm long branch!

He tried bending it with his hands. The flexibility and elasticity were just right!

As for the rope, he would use his own shoelaces!

First tie one end tightly, then bend the wooden stick into a bow shape and tie the other end tightly!

In less than three minutes, a small and simple drill bow was completed!

Preparing tinder was also easy. He found two dry leaves, rubbed them quickly in his palm, and it was done.

He then found a piece of dry wood about 15 centimeters long and a thick piece of wood!

He rounded both ends of the wooden stick on a rock and wrapped it twice around with the shoelace on the bow. He put the thick wood underneath as a base and pressed down on it with a seashell!

Although the materials were not perfect, at least they were usable.

With his left hand pressing the seashell down and his right hand waving up and down, the wooden stick did spin rapidly!

It felt really tiring!

After pulling the bow for a while, Lu Zhe’s arms started to ache.

It seemed that strength alone was not enough, physical fitness also needed to be improved!

With no other choice, he had to try a different posture!

He changed to hold the end of the bow with his right hand and swung it up and down. His arm only needed to exert force when pulling back!

Well, you couldn’t say it didn’t feel much more comfortable this way!

After a while, a small pit had been drilled into the thick piece of wood!

But this was just a start. To really ignite a flame, continuous patience and perseverance were still needed!

After half an hour, Lu Zhe had drilled out quite a lot of wood shavings, and the color of the wood shavings had started to darken. Lu Zhe knew that the end of the drill bit had heated up!

At this time he couldn’t relax, he still had to keep going!

At the same time, the girls had found quite a few "good stuff"!

Small bottles contained hermit crabs of various sizes, and plastic bags contained colorful shells!

Perhaps in their eyes, how much protein and calories they contained was not important, looking good was the way to go!

"We’ve found so many things, Lu Zhe can’t look down on us now!"

"It's a pity no hairy crabs were found! But it's also good, we found a lot of paddle crabs!"

"Aren't those small sea crabs?"

"And they’re very small. If you don’t look closely, you’d think they were dimes."

"By the way, do you guys know how to eat hermit crabs?"

"I don’t know, maybe Lu Zhe knows how to eat them!"

"Let's go see what he's doing!"

Supporting each other, the four girls returned to the campsite, but didn’t see Lu Zhe!

Ning Shu tiptoed and looked around. Seeing Lu Zhe sitting on the lawn not far away doing something unknown,

"Over there!"

"Let’s go!"

The four girls walked over, but at a distance of more than thirty meters from Lu Zhe, the four of them inexplicably stopped at the same time!

"Huh?"

"What is he... doing?"

Not far away, Lu Zhe was sitting on a rock with his back to them. His right hand was waving up and down vigorously, doing something unknown!

The four girls looked at each other in blank dismay!

Tang Xiaoguo said, "Who knows... what he's doing?"

Lin Qianqian said in puzzlement, "Why not just go over and ask?!"

"No!"

Ning Shu seemed to suddenly understand something. She looked extremely solemn. Her eyebrows were slightly furrowed, her face pale, and a little flushed!

Jiang Yao asked in puzzlement: "What's wrong, class president?"

Ning Shu pursed her lips and said painfully, "I didn't expect that he... he was actually doing that legendary kind of thing?"
