Live Wilderness Adventure

Chapter 164 Gulululu (seeking monthly ticket)

"The bowstring drilling method requires several pieces of wood, a drill shaft, a drill board, a backing board, a stick in hand, a piece of rope and the most important tinder to make a kindling, and then use a knife or other sharp tools processing of these raw materials."

Wearing a spare brown robe, Bi Fang searched around in the bushes. He picked up a branch and checked the hardness with his fingernails, but found that it was not suitable.

"The principle of the bowstring method is the same as that of the hand drill method, but the structure is slightly more complicated, because it replaces part of the labor with instruments, and converts elastic potential energy into kinetic energy in exchange for higher efficiency."

"So in terms of material selection, bow drills are the same as hand drills, so I won't go into details here."

The shrubs were very lush, and Bi Fang quickly found a suitable drilling shaft. It was a tree five or six meters high, with a bunch of small red fruits growing on the branches.

It may be that the fruit looks wrinkled after a long time.

Bi Fang cut off a small branch with a harpoon.

"Last time I used burdock, this time we can use it, elderberry."

[Elderberry? It sounds familiar. 】

【I know, it's Dumbledore's old wand! 】

[Excuse me, can this elderberry of yours be used as a magic wand? (funny)】

[Damn, I remembered now that you mentioned it. Feelings are the material of the Elder Wand, which is elderberry! 】

[Is this fruit edible? It feels very similar to Yagoda in Mohe]

Bi Fang knew that everyone was joking, so he joked.

"That may disappoint everyone. I don't know how to make wands, but only drill shafts. Elderberry is soft in the middle, but the rod is harder and has pith, which can produce more and bigger sparks than the last time burdock. It's even more appropriate."

"As for the fruit." Bi Fang stretched out his hand to pick up the small grape-like red fruit, but he didn't expect that a bunch of them fell off as soon as he touched it.

"Elderberry fruit matures from September to October, and these are already rotten, and even if they are not rotten, we can't eat them, because elderberries contain a kind of glycoside, which is the raw material for making cyanide. , we can’t eat it directly.”

The audience felt very disappointed, thinking that this fruit was similar to the one in Mohe, and it was hopeful for lunch.

With the drill shaft, the requirements for the rest are not high. It didn't take long for Bi Fang to find all the materials.

On the other side, Etienne also dug the pit as required.

Bi Fang touched the stones in the pit, nodded with satisfaction, and explained in French the reason for laying stones in the pit.

"The existence of geese and glider prevents us from being too far away from the river bank, so the nearby soil is relatively moist, and we must choose a dry place to light a fire, so that the fire is easy to light. The stones laid at the bottom of the fire pit are This function separates the wet soil."

"And you must use dry stones. Wet ones, especially stones on the riverbed or the bottom of the valley, must not be used. Such stones will produce steam when heated, which will cause an explosion. It is very dangerous. It doesn't matter if you can't find a completely dry one. Remember No stones that have been soaked in water."

[Thin, too thin. 】

[Learn another small detail]

【Excuse me, are you polite? 】

[Is it thin enough to pick a lock? 】

Netizens started to make noise again, these people can play the barrage anytime and anywhere.

Bi Fang ignored it and processed the materials on his own.

"The length of the drill shaft should be at least as long as the distance from the tip of the thumb to the tip of the index finger when you open your hand, so that it is easy to operate, and then the top end should be sharpened to make it round and smooth."

"If the width of the drill plate is more than twice the thickness, it is easy to step on it with your feet and keep it stable, and the thickness of the backing plate should also be greater than the diameter of the drill shaft."

"The stick in your hand, which is the fire bow, is best to be slightly curved. Straight sticks can also be used, but it is best to have a certain curvature, so that it is easy to operate as a whole."

"For the rope, we can use shoelaces. If the shoes you wear don't have shoelaces, you can also make a temporary one with tree fiber."

Bi Fang split a gap at one end of the drill board, dug out a small hole, and gathered the fine scraps scraped from the coniferous trees into it to serve as tinder.

He then cuts small holes in one end of the backing plate, which are used to hold the main drill shaft.

At that time, the tip of the drill shaft will be inserted into the drill plate, and the tail will be stuck in the backing plate, between the two plates, so that the drill shaft will not damage the palm when rotating at high speed.

Then Bi Fang took out the shoelaces and tied the two ends of the stick, and wound the drill shaft around the rope, so that the stick and the drill shaft formed a cross.

The whole set of movements is orderly, and it looks like an old master of survival.

"We need to control the tightness of the rope. It can neither be loose enough to allow the drill shaft to slide up and down, nor can it be so tight that it cannot move at all. The ideal state is that the drill shaft can barely rotate after using a certain amount of force."

Etienne looked on in amazement and couldn't help but ask, "How many ways do you have to make a wild fire?"

"Haha, I really haven't counted this." Bi Fang raised his head and thought about it carefully, "There are probably seven or eight different ways to start a fire in different environments, and four of them are caused by friction."

Étienne was shocked: "So much?"

"Actually, there are not many. There are only a few that can be used in different environments. After all, the environment will change, and the method must also be changed. We in China call this "adapting measures to local conditions." Bi Fang tightened the drill shaft and looked at Etienne, "Why? , want to learn?"

Étienne nodded.

"If you want to learn, I can teach you when you get back." Bi Fang smiled, and then began to shoot.

Clamp the drill shaft on the drill plate and insert the tail end into the small hole in the backing plate. Bi Fang stepped on the drill plate with one knee, pressed the backing plate with his left hand to control the pressure, and began to move the firebow back and forth smoothly and powerfully with his right hand.

Soon, gray smoke began to emerge from the drilling board, and many spectators were in an uproar.

[This efficiency is too fast, much more convenient than a hand drill]

【Fast is fast, but I feel so complicated, I can't remember...】

【Me too. 】

Seeing the smoke coming out, Etienne was very excited, and his eyes were full of admiration.

Start a fire out of thin air, it's amazing!

But Bi Fang didn't stop, but continued to pull the fire bow. After seven or eight minutes, the smoke became bigger and bigger, and he didn't stop pulling the bow until there was a flash of red light.

At this time, there was already a charcoal fire on the drilling board. Bi Fang carefully pulled out the drill shaft, then moved the charcoal fire to the prepared firelighter, held it in his hand and blew it gently.

Thick smoke billowed, and the flames flickered in the smoke. Gradually, the smoke became smaller and smaller.

A flickering flame rose and then spread rapidly, enveloping the whole firelighter in flames.

[Awesome! 】

[Zeng Hang gave the host meatballs*1000—too fast, Lao Fang is too fast! 】

[Excellent efficiency! 】

"call!"

Bi Fang heaved a sigh of relief, and threw the flame into the fire pit. Etienne, who was beside him, quickly threw the dead branches into it, and the flame grew rapidly.

Sitting by the fire, Bi Fang felt the long-lost warmth and felt much more comfortable.

Etienne on the side squeezed the wet clothes dry and put them on the fire rack to bake.

"The bow drill method is very convenient and has many details, so it is difficult for those who do it for the first time to succeed, and it is not suitable for novices."

"Just like the tightness of the rope also determines the flexibility of the bow. During use, the length of the string may need to be adjusted. For convenience, experienced people will tie a dead knot at one end and a knot at the other end when binding the rope. Slipknot."

"Drilling can also use some oil to increase lubrication and increase running-in performance, so I deliberately chose conifer tinder, which is rich in oil."

It is these inadvertent little details that Bi Fang can make this fire so successful.

Etienne continued digging at the side, and he was going to build two more fire pits so that the clothes could be dried separately and dried faster.

He doesn't know how to survive in the wilderness, so he can only help out with these small things, trying not to hold back.

Bi Fang on the side is also very comfortable, as if someone is helping him, don't care about anything, just warm up quietly.

It has to be said that although Etienne is only fourteen or fifteen years old, he is 1.7 meters tall, so it is difficult to treat him as a child.

Étienne shook the clothes and re-dried one, when suddenly there was a strange noise.

gurgling

He is hungry.
