The dead wood has many curved branches, breaking off a thicker branch.

Xiao Lingfeng used a bone knife to dig two grooves at both ends of the curved branches, "This is a simple bow body, everyone tries to use wet wood when making the bow body, because the toughness of wet wood is high, and it will not break due to deformation when pulling." ”

Then he untied his shoelaces and stretched them out.

"The bowstring is replaced by a shoelace, which is usually extremely strong and can be used as a survival tool when necessary, and with this lace I can easily get fire. ”

"I don't understand what Brother Feng is going to do, but it looks like this posture is going to be real. ”

"According to Brother Feng, it is to make something similar to a bow and arrow, as for how to operate, I really don't know. ”

"I've seen prehistoric documentaries before, where the ancients used something like a bow and arrow to pull a drill stick, so that they could get fire very quickly. ”

"What I want to say is, hurry up and get on the lighter in the props team, you see that the girls are about to freeze, I feel so distressed. ”

"Such a beautiful girl and a cute Lori actually followed Brother Feng to the wilderness to suffer, it's so sad to see their down-and-out appearance, Brother Feng is so bad!"

"This kind of show is real, I've been looking for this kind of hyper-real live broadcast, I like it very much!"

Xiao Lingfeng looked at Duan Xuerong who was curled up with some distress, this girl has always been holding the sleeping Lingling, for the comfort of the little girl, she can only grieve herself in a posture there, it is estimated that her arms and legs will be sore.

The temperature in the desert was getting lower and lower, Xiao Lingfeng was only wearing a short sleeve, and he could clearly feel the biting chill like a needle prick, quickly seeping into the flesh from the pores of his skin.

Goosebumps soon formed on the strong arm, and now the only solution to this embarrassment was to start a fire quickly!

Xiao Lingfeng took the bone awl he had just picked up, "This broken bone looks like an awl, its tip is sharp enough to penetrate this dry branch, I can use this awl to penetrate this drill wood." ”

Bones are very hard, and as early as ancient times, people used bones to make some javelin hooks and the like to catch animals, these bones are very hard and can be used as basic knives after simple processing.

"Now that this drill wood has been penetrated, this hole in the middle is very useful, and with this hole my fire efficiency will be twice as effective with half the effort. Xiao Lingfeng passed the shoelace through the hole, "Thread the shoelace through, and then wrap the shoelace around the drill wood a few times, remember to keep the attitude of winding and don't let the shoelace loose." ”

"Then I tied the ends of the laces to this bow drill, and the bow drill I designed was just the right length, basically in a tight state, and it was just such a simple bow drill. ”

"Are you finally going to start drilling wood for fire? This seemingly complicated thing is not very powerful. ”

"I don't understand why you have to drill a hole in the middle of the wood, when you can tie the laces directly to the stick. ”

"Why do you have to use shoelaces, in case you can't take them off if they are tied to the bow drill, how will you walk tomorrow, in fact, you can use other vines instead. ”

"In the vast desert, where do you go to find vines and the like, you can only use shoelaces. ”

Xiao Lingfeng explained, "The reason why I use shoelaces is because after a while, I will desperately pull the bow drill, so that the wood continues to rotate violently, so that I can always increase the heat, and the shoelaces have a sleek appearance, which will greatly reduce the friction after contact with the wood." ”

"In fact, this is the same as walking on the ice, the soles of our shoes will have strong friction when they contact the ground, so that we can stand firmly on the ground, because the ground is rough, and the surface of the ice is extremely smooth, which greatly reduces the friction, and we are more likely to slip and even fall when we walk, which is the importance of friction!"

Although Xiao Lingfeng did not graduate from junior high school, the survival skills he learned in the later stage are all based on science, which need to be applied to physics.

began to drill wood for fire, Xiao Lingfeng sharpened the tip of the bow drill, so that it would be very easy to drill!

"When drilling wood for fire, remember to dig a small hole in the dry wood you are going to start drilling, so that the bow drill does not leave that range, and then put a tool on top of the bow drill that can control it, here I choose this bottle cap, which allows me to hold it down and push the force downwards, which will accelerate the temperature rise between the woods, so as to reach a critical point. ”

After getting ready, Xiao Lingfeng said, "Don't say much, everyone look carefully, I will light the fire in a few minutes!"

Xiao Lingfeng's physical strength is very sufficient, and when he pulls the bow drill, it is naturally very powerful, and the wooden drill rotates rapidly on the wood, almost without stopping for a moment.

"I'll go, this speed is too fast, did Brother Feng practice it himself before?"

"People with wives can also have this kind of hand speed, I'm really puzzled, do you have that special hobby?"

"Who said that if you have a wife, you can't have hand speed, foreplay needs to be done enough, and hand speed and strength are also very important. ”

"Ah~!Ah~~!What are you talking about, why can't I understand it at all, I'm still a high school student~!"

"Sister don't pretend to be pure, pretending to be innocent will be criticized!"

"Take me one~!"

Xiao Lingfeng didn't pay too much attention to the barrage, but pulled the bow body vigorously, it was a little cold just now, and now this high-frequency work actually began to sweat profusely again.

"Friends, the flame is about to ignite, I can smell the smell of burnt wood, it is a very fragrant smell, but the more you get to this moment, the more you can't stop, don't let go until the flame is burning!"

Pulling desperately, the bow drill drilling violently, the rising white smoke can be seen in the live broadcast room.

"Now that the charcoal fire has formed, I just need to gently put the charcoal fire into the velvet prepared in advance, and remember to protect this young flame!"

A little red charcoal fire was clearly visible in the night, and the fire of hope was put into the hay and shook slowly.

"The flame is very weak, remember not to blow violently or shake violently, that will really make the flame die immediately, it is not strong enough now!"

Xiao Lingfeng gently shook the small flame, as if he was caring for a baby!

It didn't take long~!

The baby returned, and a fiery red flame burned, it was so dazzling and warm in the dark night, seeing it Xiao Lingfeng and Duan Xuerong laughed heartily, and the flame of life was ignited!
