Leave one of them generally used to drill stalks, and the remaining half is kept for backup, and when it rains heavily, this little bit of wooden stick is also a rare resource.

It's not so much about saving as it's about helplessness.

The rain was getting heavier and heavier, and there was no way to get out, Jiang Liu'er searched carefully in the cave, except for the small hole in the depths of the cave, he didn't dare to go in, and searched all the other places, but only found a small bundle, or a bunch of dry firewood, and some dry weeds, which could be used as velvet for drilling wood for fire.

These sticks seemed to have been thrown in the cave for a long time, and they were all dried up one by one, and I didn't know what kind of plant they were, and Jiang Liu'er couldn't take care of them so much.

If it doesn't dry out, it can't be used as a material for drilling wood for fire, but Jiang Liu'er now only needs to scrape off the dry bark on the surface of the stick.

Following the dimmer and fainter light, Jiang Liu'er found a few more stones, some large and some small, and the material looked like basalt, which was very hard.

Time flies, and Jiang Liu'er is also a little anxious.

It's about to get dark, and if you don't succeed in making a fire, you won't be able to respond to even the basic dangers at night on a desert island that is pitch black and you can't see your fingers.

Just like the cobra she encountered before, Jiang Liu'er gently brushed the cobra corpse that was still hovering and twisting together, and she couldn't help but feel a little afraid in her heart.

While quickly picking out a palm-sized, relatively thin, only about the thickness of a palm, he put the selected drill stalk on a relatively thick wood in front of him and hung it in the air, then sat down and clamped it with his feet, and quickly scraped off the bark attached to the drill stalk with an angular and thin-looking sharp basalt stone chip.

The stalks were already dry, and it didn't take much time to scrape off the bark.

It's a good idea to carefully gather the scraped bark together and gently shred it as a preliminary velvet.

Next is the base plate for the processing of the drilled wood for fire.

First, use the tip of the same stone chip to drill a hole in the bottom plate that is slightly softer than the drill stalk, not too deep, only the tip that can accommodate the drill stalk.

Then you also need to make a groove on the side of the hole, so that the spark can fall smoothly from the hole.

It's easy to say, but the action of drilling and digging grooves took Jiang Liu'er several minutes.

Although the blade of this stone chip is relatively thin and easy to use, it can be used to cut things, and it can be used to drill holes, which is indeed a bit of a knife for killing chickens, because the tip of this basalt stone chip is really not sharp.

Relatively speaking, it is better than nothing, but the tip of this stone chip is also the best among the stones that Jiang Liuer worked so hard to find.

And in order to shorten the time, Jiang Liuer also took the trick and moved the position of the small hole that accommodated the drill stalk to the place near the edge of the bottom plate, so that although it is not too good in the long run, it is easy to cause the rupture of the bottom plate, but in a short time, it can greatly reduce the time of work, and digging a groove from the end of the small hole near the edge can also really reduce the time.

I simply dug small holes and grooves, put one end of the drill stalk in it and compared it, but found that it was still not suitable.

The thickness of the drill stalk seems to be obviously larger than the diameter of the hole, and there is no way to make a fire, but if you use stone chips to expand the diameter of the hole in the bottom plate, you will definitely waste a lot of time.

Jiang Liu'er was in a dilemma for a while.

But time did not allow him to hesitate, the light became dimmer and the visibility in the cave became less and less.

Gritting her teeth, Jiang Liu'er suddenly had a flash of inspiration and thought of a simple way to make use of her strengths and avoid her weaknesses.

Although the drilling of this stone chip is very ordinary, but the ability to cut the slices is extraordinary, at this time, there is no need to enlarge the small hole in the bottom plate, only need to sharpen the tip of the drill stalk.

Such a simple truth, I didn't expect it.

slapped his head on the head, which seemed to be a little rusty, and didn't dare to waste any more time after he was in a hurry, so he just did it.

After just a few breaths, even chopping and chopping, Jiang Liu'er, who was holding his breath, quickly sharpened the drill stalk, and compared it with the small hole on the bottom plate, which was just right, and he was suddenly happy.

The last thing to do is to use two wooden sticks of similar thickness to pad under the bottom plate to form a space, support the bottom board, and then rub the dry bark into fine sawdust with your hands, pick up the hay next to it and knead it together as velvet, and then put it on the end of the bottom plate near the groove to take on the falling sparks.

This is also done so that the hot wood chips produced can come into contact with more air and support combustion.

……

With the basic preparations out of the way, the next step is the really most important stage...... Drill wood for fire.

Anyone who has seen survival in the wilderness knows that the key to drilling wood for fire is to correct the drill stalk and rub it with both hands, to speed not strength, to last without force, so as not to break the drill stalk or grind blisters in the palm.

The most useful way to drill wood for fire is not to rub the stalks with both hands.

This method is not only time-consuming and labor-intensive, but also highly skillful, and has a high chance of failure.

Therefore, in modern times, many survival experts who understand the principle of fire will use the method of making fire with a fire bow.

The Fire Bow is an easy fire-making technique, but it requires a lot of practical practice. Rubbing a hard piece of spindle-shaped wood against a cork base will initially drop fine pieces of wood chips (which can be used as tinder) and then heat up at the friction site. Pine, Besselt, and bamboo are typical softwoods; Oak and wood can be used as hardwoods. Both hardwoods and softwoods must be dried.

Of course, there is also a technique called the Iroquois method of ignition, which was invented by the Iroquois and is quite efficient. One end of the drill shaft is wound with two ropes, and the other end of the rope is fixed to a rigid transverse plate. A hardwood wheel is used as an accelerator in the middle of the drill shaft.

When the rope is wound and pressed down on the transverse plate, the drill shaft can be rotated extremely fast and sparks will be drilled.

……

However, neither time nor tools nor materials allowed Jiang Liu'er to do this, and if the weather cleared tomorrow, he would be able to go out of the cave to find food and materials to make a fire bow, so that his survival would be easier in the future.

This first night, without any means of survival, is often the most difficult.

What I can do now is to use the most primitive techniques of these simple materials to make a fire as soon as possible, so as to comfort my slightly frightened heart a little.

Because he had never tried to survive in the wild before, nor had he used the method of drilling wood to make fire, but he had only seen it on TV, Jiang Liuer really didn't know how high his success rate could be.
