"Make fire?" Lin Qingxue chewed the white and tender coconut meat, and tilted her head cutely to look at the garbage scattered all over the place, "What do you use to make fire?"

There were all sorts of marine debris picked up, such as drink bottles, tangled fishing lines, and a glass bottle with a few rusty iron nails embedded in the wood.

"See this iron nail?" Qin Fengyi clamped the iron nail with two stones and pulled it out hard, the man with the Qilin arm pulled the nail very easily, and then picked up the glass bottle, "The bottom of this bottle is arc-shaped, theoretically speaking, it is something similar to a convex lens." ”

Lin Qingxue felt that she was offline, what kind of logic is this, "The characteristic of glass is transparent, yes, but it is very brittle, if you fall, it is difficult to guarantee what shape it will be broken, and your convex lens may be destroyed." ”

"So, this nail is used!" Qin Fengyi took the nail and put it in the glass bottle, "The front end of the nail is very sharp, put it in the bottle, and shake it up and down like this, it will cause the nail to produce an impact force, control it to smash the edge of the bottom of the bottle, which will form a small crack at the bottom of the bottle, and over time it will become bigger and bigger, and finally the bottom of the bottle will be completely removed." ”

This is also what Qin Fengyi learned from Brother De when he was watching a survival program, that buddy is so old at survival that he doesn't bring anything and doesn't wear clothes.

"Uh...... That's a bit far-fetched. Lin Qingxue looked at Qin Fengyi's operation, and it didn't take long for it to really succeed!

It worked!

It worked!!

"See it, this is wisdom!" Qin Fengyi pointed to his braincase, the survival show he watched before was really not in vain.

"Okay, it's really amazing!" Lin Qingxue handed over a piece of white and tender coconut meat again, and Qin Fengyi opened his mouth to eat it.

Both of them have not eaten rice for three days and three nights, and now they are so hungry that they are so hungry that their chests are pressed against their backs, but they need to make a fire before that.

Fire is essential for survival in the wild, keeping warm, cooking, distilling fresh water, and banishing the terrible darkness.

"We don't know when help will come, all we can do is wait and stay alive in the meantime. Qin Fengyi and Lin Qingxue looked at each other, "Now we have a few coconuts, but we can only solve the urgent need, I believe that with the fire, we will be very comfortable at night." ”

"Actually, I want to have a good meal, even if it's a hard steamed bun. Lin Qingxue tried her best to restrain herself from thinking about those delicious foods, such as chicken cutlets, hamburgers, fried tenderloin, sweet and sour pork ribs, etc., she didn't dare to think about it.

"Don't worry, the last thing in the sea is food, as long as I do a good job of this device, we will be able to make a fire in no time, and then just wait for the barbecue!" Qin Fengyi was still fiddling with some wooden sticks.

"What are you doing with this? I think you can just use this to make a fire. Lin Qingxue carefully picked up the bottom of the bottle covered with sharp glass ballast, and put it at an angle, through the sun's rays can indeed condense heat.

"The bottom of this bottle is not easy to make, after all, it is single-sided, it can only be a concave lens, its concentrating effect is not very large, and it takes longer to use this to make fire. "The device made by Qin Fengyi is a wooden stick inserted into the sand, and there are two small wooden strips tied to the outer diameter of the wooden stick, which are parallel to each other and can be used to place things.

The setup is simple and takes just a few minutes to complete.

[Host crafts lazy wooden frame, carpenter building proficiency +1......]

Am I rubbing?

Just making a small thing casually can increase proficiency, Qin Fengyi secretly rejoiced, you must know that there are many trap wooden house production techniques in the sub-professional carpenter building, and as long as you are promoted to the intermediate level, you can master more drawing techniques.

The icons that can be made above the intermediate level are all gray, but some can be roughly seen, and they seem to be ballistae catapults or something, and there are also looms......

This system is really funny, what's the use of a ballista? Hunt sharks in the water?

That said, hunting sharks with a ballista seems cool!

Qin Fengyi was making, and Lin Qingxue was crouching in the shade of the tree, looking at the operation of the slightly handsome boy, and said that serious girls are the most beautiful, and serious boys are also very good!

Xiao Nizi originally held her cheeks with her hands, but when she saw him basking in the sun, she was a little careless, picked up a few huge banana leaves on the ground and walked over to help Qin Fengyi shade the sun.

"Thank you......"

After hearing his thanks, Lin Qingxue smiled very cutely, "What's polite, we are on a desert island together, and we should take care of each other." ”

After that, Xiao Nizi was a little apologetic, if it wasn't for my dad to sponsor the trip, you wouldn't have been shipwrecked, it's all my fault......

"You should be able to understand what I'm doing, right?" Qin Fengyi finished the device and was debugging.

"I seem to understand, you plan to put the bottom of the glass bottle on top of this, so that you don't have to take the glass piece to make the fire yourself, we can also do something else!" Lin Qingxue understood, although this kid is a dick scumbag, he is quite smart.

Qin Fengyi put the bottom of the glass bottle on the wooden stick, and then began to adjust the angle, "That's right, this concave mirror takes a long time to ignite the velvet, after I adjust it, I can do something else, so that the fire can be obtained." ”

It is difficult to ignite the convex lens, and it takes a long time to ignite the velvet, and only continuous heating can ignite the velvet.

After adjusting the angle of the convex lens, Qin Fengyi was vigorously rubbing a ball of debris scraped off the dried coconut shell, and after crushing it, he placed it under the circular bright spot formed by the convex lens, which was not only bright but also very hot.

"Okay!" After placing a lot of small firewood, Qin Fengyi clapped his hands, "When the velvet is lit, these small firewood will also be completely ignited, and then it will continue to ignite these big firewood slowly, without us looking, the sun can make its own fire." ”

"Not bad, boy, you're really smart!" Lin Qingxue smiled lightly, blinked her star-like bright eyes, and patted Qin Fengyi's shoulder with her little hand, "Let's go hunting at the beach now, I have a hunch that I can catch a lot of crabs and pick up a lot of conch." ”

A makeshift ignition made of rough wood and glass was working on it, and the two walked together towards the sea.

"Wow~~ It's really beautiful here!" Lin Qingxue praised from the bottom of her heart, after approaching the sea, the more she felt that this bay was more like a paradise, the water quality was too clear, blocked by the coral reef at the junction of the shallow sea and the deep sea, there were not many waves here.

"Indeed, it's beautiful here!" Qin Fengyi was not only looking at the scenery, but also looking at Lin Yuxi, the girl had a delicate face, three thousand green silks fluttering in the wind, and there was a hint of lively and lovely playfulness in the mess.

"Look there, wow, we're rich!" Soon, Lin Qingxue made a discovery, as if she had found a treasure.
