Yes!

In the gearbox, there is indeed a part that is not iron, but stainless steel!!

All the other parts have a layer of black carbon and a little rust, but this long shaft is still shiny.

The advantage of stainless steel is that it is not easy to rust, the hardness is higher than that of iron, the toughness is higher than that of iron, and the density is several times that of ordinary iron.

Some medical devices are stainless steel springs, which are far more elastic and compressible than iron, but the price is naturally hundreds of times that of iron springs.

What Zhao Yunxiang wants to do most is bow and arrow, because the bow and arrow have a long range and great lethality, and it is relatively safer than a one-handed sword and dagger.

And the bow body of the bow can be completely forged with stainless steel, which has high hardness and toughness, so it is a necessary forging material.

However, before forging a bow and arrow, you need a hammer that is easy to smash, and as for this anvil, the gearbox can do it!

The thick shell of the gearbox is thick, its inner wall is 3 cm thick, it is shaped like an angular cube, and the outer surface is extremely flat.

Destroy the gearbox and take out a number of long shaft gears, one of the largest gears, weighing about 15 pounds, which can be used to make a hammer.

Before forging iron, it needs to be normalized, which means that the hardness of the metal is reduced, so that it becomes soft, less prone to cracks, and easier to process in the forging process.

Put the huge gear and the long stainless steel shaft directly into the fire, and add a lot of firewood to make the flame burn stronger.

While the parts are on fire, you can do a little carpenter building, and at the same time, you can strengthen the shelter as much as possible.

The ideal shelter is not just a double-storey wooden house, but also a spacious fence yard, part of the nursery, etc......

The current bamboo house is still short of a roof and a bamboo ladder to the second floor, which can be temporarily slowed down, and at present, Zhao Yunxiang wants to do more than a fence yard.

With a sturdy fence, you can defend against most of the ferocious predators, and you can even set traps in the fence yard, if a black monkey or a wild man dares to climb the wall to enter, it may trigger the trap.

In fact, making traps can also increase the carpenter's skill in building, but at a slower rate.

......

"Give you a toothbrush and toothpaste, brush your teeth well!" Lin Yuxi handed over a small leaf, and on the leaf was a lump of black and white sticky.

"I'm so sensible, let's wait until I'm done brushing my teeth... Hey, hey, hey~~!"

The first thing I do when I get up every morning is to see the energetic Lin Yuxi, this little beauty is petite and exquisite, and she looks very beautiful without makeup.

"Hey, hey, hey, your sister!" The girl crossed her waist with one hand, pointed at Zhao Yunxiang's forehead with the other hand, and pouted her red cherry mouth, "You are a dead pervert, thinking about these dirty things all day long!"

"I'll just ask you if it's okay?"

"No way!"

The girl shook her head again and again, no!

Absolutely not!

The head of this snake is like an eel, thick and powerful, and the thief is particularly slippery, that touch.... Hey~~~~~!

"Ahem.... You guys have a good relationship. Han Xue stroked the wavy curls on Xiang's shoulders and smiled slightly, to be honest, she was very envious, but she was very envious of her students.... It's a little... Perverted.

"What, you brush your teeth first, I'll go over there and take a look!" Lin Yuxi pointed to the side of the bamboo forest, and also collected a few handfuls of geraniums by the way, guessing that this chick was going to the toilet, and carrying the leaves can indeed effectively prevent mosquito bites.

The girl is wearing a white skirt with some stains, a pair of slender and fair-skinned beautiful legs stride away, the white flowers are particularly beautiful, the straight is twisted and twisted, and the waist-length soft ponytail ripples in the slender waist.

"Lin Yuxi, remember to pull up your hair when you, otherwise it will be easy to get!" Zhao Yunxiang stared at the girl's back and thought for a while, and shouted loudly.

"I'll strangle a grass~~!" Listening to the reminder of the goods, the girl almost fell to the ground, why is this animal so annoying?

"Poof~~" Han Xuening couldn't help it, and her laughter trembled, "Why didn't I find you so humorous before." ”

"Teacher, this is not called humor, this is a hint of care. Zhao Yunxiang stared at the first beautiful teacher in Nancheng and said slowly, what he cared about most was the white neck and the slightly open collar.

"Hmm..."Han Xuening naturally felt Zhao Yunxiang's gaze, the way this kid looked at himself was not the kind of possession of the red fruit, but a kind of appreciation of beauty, the kind of eyes that were so pure that they couldn't do it.

I guess there is no one who can give full play to color and appreciate art!

"That...."Han Xue Ning groaned for a while, biting her red lips tightly, and finally asked softly, "Isn't it dishonest that I sleep?"

"It's okay, it's quite soft, much bigger than Lin Yuxi's, and it's very warped, unusually full!" Zhao Yunxiang held his chin and pondered again, as if he was reminiscing, and finally emphasized, "It's a big plump peach, Teacher Han, you are so amazing!"

I'll it~~!

What does this have to do with being awesome??

Han Xuening was directly stunned, what did this kid do last night, why don't I know anything??

"Ahem... Classmate Zhao Yunxiang, you should still brush your teeth, brush well, don't lick the toothbrush, Lin Yuxi rinsed in the sea for a long time after brushing his teeth, you can't lick the saliva left!" Han Xuening specially prompted, admiring Lin Yuxi in her heart, that little girl guessed too right.

At the beginning, Lin Yuxi bet with her that Zhao Yunxiang would definitely lick the toothbrush when he could brush his teeth, the girl was too familiar with the animal, and sure enough, this thing was licking selflessly.

"Oh.... Misguided. ”

Girls obviously love cleanliness, and the necessary cleaning must be there, and cleaning the mouth is the most important.

This so-called toothpaste is made from charcoal powder mixed with coconut pulp, and although it doesn't look good and doesn't taste so sweet, it's better than rubbing it with a toothbrush.

As for this toothbrush and bamboo tooth cup, the three of them all use the same, the two girls got up early and have finished washing, only Zhao Yunxiang has not cleaned up.

Although the curly toothbrush is not very easy to use, but compared with the fingers, it is more than ten times better, the friction of charcoal and the superb adsorption ability can effectively remove tooth stains, and the faint fragrance of coconut milk can freshen the breath, so as not to nausea and vomiting when brushing teeth.

After simply brushing my teeth, I feel a lot more refreshed, in fact, the happiest thing is to use this curly toothbrush, you must know that this toothbrush was used by Lin Yuxigen Han Xuening, although it was washed in the sea water for a long time, Lin Yuxi, this chick, was also stained with a lot of fine sand, all stuck in the curly toothbrush.

In fact, Zhao Yunxiang didn't expect that there would be many things, the toothbrush is a piece of marine garbage, before it was discarded, it may be an old lady using it, or it may be an old man using it, or even dyeing his hair or brushing the toilet, and then it became garbage before he came here along the ocean current.

However, before using it, the girl put the toothbrush in the paint bucket and boiled it for 3 hours, even if she brushed the toilet, the bacteria were completely clean.

After brushing his teeth, Lin Yuxi hasn't come out yet, it is estimated that it is dry, and he basically eats meat these days, without vegetables and fruits, so it is conceivable that he will digest it.

"Ah~~ Are you annoyed, this dead bird, get out of here!!" Lin Yuxi's shy roar came from the forest.
