The temperature around the kiln was terrifying, and when you looked at it from a distance, the air around the kiln was distorted as if it were burning.

"After such a long time of normalizing, it is estimated that the stainless steel has been burned red!" Zhao Yunxiang is very satisfied with the kiln he made, which can not only be used for heat treatment of metal, but even smelting!

Yes!

It is indeed possible to smelt with this primitive broken furnace, knowing that the melting point of iron is 1538°, and the inside of the furnace can be continuously heated, and the temperature produced by different wood after burning is almost different.

However, if you want to smelt, it is difficult to achieve it with the current wood, so you need to find a harder wood!

Of course, there is no need to smelt metal now, because there are ready-made large pieces of iron in the shelter, and there are many large gears and long shafts in the gearbox of the airplane, which are all semi-finished forged materials.

"This big stove is too hot, you better put on this robe, it's baked!" Lin Yuxi hurriedly handed Zhao Yunxiang a suggested dress woven from palm leaves.

The temperature after burning in the kiln is terrifying, but the temperature within a radius of 1 meter can be as high as 200 degrees Celsius, and the temperature inside the furnace is at least about 700 degrees Celsius.

As soon as he got a little closer to the kiln, his arm felt hot and painful, and Zhao Yunxiang put on the special leaf coat made by Lin Yuxi, that is, the clothes worn by honey.

To be honest, after wearing foliage clothes to cover your skin, you can indeed resist the scorching furnace temperature, but unfortunately it is still hot, a kind of burning stuffiness!

I took out the stainless steel shaft in the furnace with a wooden clamp prepared in advance, and the fire snake at the mouth of the furnace was raging, and the black smoke was billowing out, which was very scary.

It's red, it's red!

The stubborn stainless steel is directly burned red by the high temperature, and the semi-closed high-pressure furnace temperature directly penetrates into the center of the long shaft of the stainless steel, which is obviously a successful normalization.

Normalizing of metal is a kind of heat treatment, which uses high-temperature burning to change the density of iron, thereby reducing hardness and increasing flexibility!

Just like the iron wire we commonly use, the iron wire will break after being folded in half and repeatedly squeezed, but it will not be so easy to break if the wire is burned with fire and then folded and squeezed in half.

That's what normalizing is for, reducing hardness and increasing flexibility!

The forging process of the bow and arrow is very simple, that is, normalizing forging, forging the prototype and then normalizing again, the bow body needs flexibility, and does not need much hardness.

"Jingle ......"

Continuous beating, metal and metal collide to make a crisp or dull sound, Zhao Yunxiang is naked on his upper body, and every time he raises his hammer head to hammer, he will show the perfect and strong muscle lines on his body.

And the two girls who are tidying up the bamboo poles on the side will peek at each other with bright eyes, which is a benefit!

Zhao Yunxiang is not handsome at first glance, but Zhao Yunxiang, who is shirtless and iron, is handsome out of the sky.

"It's so pretty......"

Lin Yuxi swallowed a mouthful of saliva, and looked at the strong biceps, strong and open pectoral muscles, clear abdominal muscles, and the charming mermaid line.

Han Xuening didn't comment too much and was appreciating it, the two girls were working while watching the muscular handsome guy strike the iron, and there was a little comfort in this day.

Lin Yuxi and Han Xuening were beating the turquoise bamboo, releasing the water in the bamboo, and then dividing the 20-meter-long bamboo into 7 equal parts, and then these bamboo poles would have to be made into a fence yard.

As the island became more familiar, more and more creatures surfaced, and the bamboo huts, though sturdy, were limited to isolating brainless creatures like wolves and wild boars, like black monkeys and wild men, enough to open doors with tools or brute force.

Therefore, some fence courtyards must be set up around the shelter, and the fence courtyard in Zhao Yunxiang's mind is a row of thick bamboo walls, even the black monkey can't push it down, and it is difficult to climb up.

"That's a lot of water from these bamboos!" Lin Yuxi drained the bamboo water of five bamboos, and obtained a total of more than 10 liters of water, and the bottles with lids in the shelter had basically been used up, and they were all used to store water.

......

Bite~!

[The host successfully forges the bow body, and the blacksmith proficiency +5 ......]

[Host successfully forges iron arrows, blacksmith proficiency +1 ......]

Dozens of minutes later, after many times of normalizing forging, a stainless steel bow body was forged, and the bow body went through the last positive fire, and then cooled naturally, and now only the bowstring needs to be assembled.

There are also more than a dozen arrowheads made from small parts, but these arrows need to be ground and assembled with arrow shafts, which will take some time to make.

The bowstring had been preparing for a long time, and some time ago he had been searching for marine debris on the beach, including many fishing lines, as well as a metal fishing line.

Because the bow body is forged from stainless steel, it is difficult for ordinary fishing lines to bear the pulling force, so Zhao Yunxiang plans to use multiple strands of fishing line to form a bowstring.

He made a total of 3 metal fishing lines in sections, 3 nylon fishing lines, the metal fishing lines are hard and wear-resistant, and the nylon fishing lines are extremely tough, and the two need to be well matched.

3 nylon fishing lines are kneaded into one and hidden in the innermost part, which is responsible for the toughness of the bowstring, while the metal fishing line is coiled on the outside, which is the hardness and is not easy to be worn and broken.

Just like the chopsticks we are familiar with, one chopstick is broken at once, but a pair of chopsticks is difficult to break.

......

In a dense forest on the island, the fair-skinned man in black was still searching aimlessly.

"What a headache, where are they?"

The man in black muttered to himself, and through the dense woods, he saw several tired figures in front of him, and he grinned at the moment, showing his hideous messy teeth, and he stood in place waiting for those guys to approach.

Several wild men with bone weapons slowly surrounded the man in black, forming an encirclement formation, and they stared at the man in black, in the eyes of these guys, this creature was prey.

"Tsk...... You've hidden it so well, let me look for it for 2 days!" said the man in black to a few vigilant wildlings.

"Woo wow wow~~!"

One of the savages with a bony spear was shaking the weapon in his hand, the exposed evil form swaying back and forth, making the man in black feel sick.

The other two wildlings also eagerly walked forward, as if to surround the man and kill him, and they worked together perfectly, one was responsible for attracting the target's attention, and the rest were attacking from both sides!

"Huh...... Are you going to do it with me, inferior creatures?" the man noticed the wildling's movements, and grinned disdainfully, his smile disgusting, his mouth trembling.

"Ahh

The savages roared in anger and attacked in a triangular formation, the bone weapons in their hands pointed directly at the legs of the man in black, seemingly not wanting to hurt his life.

"I really don't know how William communicates with you, a bunch of low-grade monkeys!" the man in black shook his head helplessly, rolled up his sleeves, and revealed the strange mark on his wrist!

"Aga??"

When the savages saw this mark, they were stunned at first, and then they trembled and knelt on the ground and began to worship reverently, and their mouths were still saying some strange words that they could not understand.

"Now take me to your camp, I want to see her!"
