At the northernmost end of the Five Elements Sect, there is a mushroom mountain that is not big or small, with vast rock and soil, overturned slag and stones, and no grass grows.

There is an iron ore vein at the bottom of the rock and soil, and the survey shows that the ore vein stretches for hundreds of miles along the direction of the Weiran Mountains.

The history of the Five Elements Sect mining this iron ore has been more than 1,000 years, smelting stone into iron, wrought iron into steel, accumulating over time, and the waste slag has piled up into this mushroom mountain.

Not far from the entrance of the cave of the ore vein, is the factory of the Five Elements Sect for refining ore, a truss building supported by a steel skeleton, about ten meters high, thirty meters wide, and about two hundred meters long.

From the selection of iron ore, to the refining of furnaces, to the tempering of steel, the molding of pottery, to the assembly of equipment, all of them are completed here.

Towards evening, Su Jinglu brought him here, and far away, he smelled a pungent burnt smell of molten pig iron.

Workers are busy coming in and out, truckloads of raw ore are pulled out of the burrows and transported into the factory, and truckloads of slag are transported out of the factory and piled up on the edge of the mushroom mountain.

Inside is an orderly and busy scene, ore selection, rough melting, wrought iron tempering, assembly line operations.

More than a dozen men with five big and three thick, sturdy physiques, bare upper bodies, muscular, sweating profusely, wielding huge hammers in unison, striking the fiery red wrought iron.

As he walked, suddenly, a wave of heat hit, and ten meters in front of him, a cylindrical furnace with a capacity of thirty cubic meters was red, the flames were running upward, the green smoke was billowing out, and the high temperature was scorching the surrounding air.

The one who is directing the production is the great butler of the Five Elements Sect, the third senior of Su San.

Su San saw the two of them, so he walked over and greeted him: "Young Sect Master, Master Han, why are you here, the old man is far away to welcome ......"

Su Jinglu took out the small porcelain bottle containing the stone, handed it over, and said softly: "This is a little stone I collected today, you take it, add it to you before, and see if it reaches the amount of 3 tons of high-grade steel for forging." ”

"Okay, I'll go!" Su San gently took the small porcelain vase and turned to leave.

————————————

Cold Wind's attention was completely attracted by a few small monsters under the ceramic furnace.

Whew!

"Xiao Su, these fire-breathing guys are salamanders, right?"

"Yes, salamanders, also known as saloons, were brought by Yurou from the Lost Forest, and are good at breathing fire, and with the fire source they provide, they can control the heat in the furnace very well. ”

Xiao Su smiled indifferently and replied.

A total of four salamanders the size of domestic dogs sat around the bottom of the furnace hanging in the air, spitting out red flames one bite after another.

Salamanders have well-developed forelimbs, covered with black and red scales, and have a face resembling an eagle's beak, a slightly larger beak with a curved hook, dark black, and hard as iron. Saroman snakes, commonly known as salamanders, reproduce in a vegetative reproduction manner.

A salamander will give birth to a larva every ten years, and they will keep the larvae inside the fire pit until they reach maturity.

Salamanders are fire-resistant and high-temperature by nature, and can perform some dangerous operations in extremely hot conditions.

"What kind of utensils are this forging yard going to produce, and it looks like it's in full swing and busy?"

"An upgraded windmill - codenamed Raptor. ”

Xiao Su looked up at the five-meter-high cylindrical furnace and introduced. "You see, the molten iron in this furnace is what I prepared for Windranger 3.0, codenamed Raptor Raptor. The first generation of windmill windmill windranger 1, the driving energy is wind spirit stone, the second generation windmill resistant, windranger 2, the driving energy is wind crystal, this time, I want to build windranger 3, code name Raptor Raptor, the driving energy is wind element stone. ”

"The windmill is just a means of transportation, isn't it a bit too extravagant to use the Fengyuan Stone?"

A hint of cunning flashed in Su Jinglu's eyes, and he explained: "Windranger 1 and Windranger 2 have never been solved, the problem of disability in extreme weather. Now the outside world is freezing cold, and we can only use snowmobiles when we go out. Raptor No. 3 is made of high-grade stainless steel seamless welding, which can maintain stability under high-energy and high-speed conditions. Not only can it adapt to extreme climates, according to my design, it can fly in the air at a height of 10,000 meters. ”

"It's so tall, it's kind of powerful. "The cold wind was shocking, beyond imagination.

————————————

At this time, Senior Su San turned back, weighed the white porcelain vial in his hand, and said: "Young Sect Master, it's just right, fifty grams of stone, and three tons of high-grade steel. ”

"Okay, add it now. Tonight, I will arrange for the foundry to work overtime overnight to cast all the components of the Raptor at once according to the drawings I have drawn, and I will personally supervise here. Xiao Su looked solemn and meticulous.

"Everything is subject to the arrangement of the young sect master. Su San didn't dare to slack off, and called a larger salamander to come over.

This salamander is supposed to be their leader, with big black eyes, cute and well-behaved.

Su San muttered a few words, and the salamander seemed to be able to understand human words, opened its eagle hook and pointed its mouth, and waited eagerly.

Immediately afterwards, Su San pulled off the wooden cork of the small porcelain bottle and poured all the stone elements inside into the salamander's mouth, bit by bit.

The salamander took the stone in its mouth, and without delay, ran towards the furnace with its strong forearms. The sonorous front paws, not afraid of the blazing outer wall of the furnace, grasped it, and climbed up.

Sou!

In the blink of an eye, the salamander scurried to the top of the stove, and stood at the edge of the stove for a moment, staring at the big black eyes, as if something was brewing.

Then, the salamander lowered its head, and pointed its hooked beak at the fire below, and a small bright red fireball burst out of its mouth and into the furnace.

Whew!

There was a violent reaction in the furnace, and there was a crackling sound.

The salamander jumped straight from the top of the furnace and returned to its original position, spitting flames at the bottom of the furnace with the other three salamanders.

"The temperature is not enough, and the frequency of the fire needs to be accelerated. Xiao Su commanded.

Su San nodded, and from his sleeve, he took out four fire spirit stones the size of quail eggs.

The whole body of the fire spirit stone is red, and the energy is pure.

Su San walked over and fed each of the four salamanders a fire spirit stone. The salamander swallowed the fire spirit stone in one gulp, and its energy was replenished, and the rate of spitting fire increased significantly, and the tongue of fire that spewed out was much larger than before.

Under the scorching flames, the ceramic furnace became translucent, and the boiling molten iron inside was clearly visible.

As the stone slowly melted inside, the molten iron gradually turned from fiery red to blood red. Inside the entire furnace, the churning blood-red molten iron was shining red, like a blooming rose.

"Su San, go and arrange for the foundry to come over now, I'll watch here, and after an hour, open the furnace and release the water. Su Jinglu stared at the furnace thoughtfully.

Under the scorching heat of the high-temperature stove, several of them were red on their faces and sweating profusely.

"Yes!"

The salamander, worthy of the famous flame spirit animal, continuously spits out tongues of fire, maintaining the temperature in the furnace at around 3,000 degrees. Ordinary fuels, refined coal, oil oil, and gas, simply can't do this.

Four salamanders, tirelessly spitting tongues of fire, themselves unaffected by the heat.

"By the way, Xiao Su, adding the stone, why can you change the properties of the steel and upgrade it to a special steel, have you studied this?"

The cold wind was sweating profusely, and his hair was soaked, so he wiped the sweat from his face with his hand and asked with a smile.

"With the addition of stone in it, the bonding characteristics of the stone molecules can firmly polymerize the steel molecules together, which not only improves the density of the steel, but also makes the toughness and stiffness more balanced, and doubles the Poisson strength. Rubble changes the physical properties of steel, and it also changes the chemical properties. ”

The gap between stainless steel and special steel is not a little bit.

"That said, the finest steel can be used to make high-grade armor and weapons. It's a pity that the material is too rare. ”

"It's too hot here, let's go out and talk. ”

Xiao Su smiled slightly, and on the face of fine skin and tender meat, beads of sweat the size of beans fell from her cheeks one by one.

————————————

At night, the breeze is gentle.

"It's much cooler outside!" the cold wind breathed freely, a burst of coolness.

The whirring valley breeze, with cool air, blows on the face, and a refreshing feeling is as cold as bathing in the stream.

Xiao Su smiled slightly: "Steelmaking is a hard job, high temperature roasting, and the danger of being sputtered by molten slurry. It is even more difficult to refine high-grade steel. From the selection of ore, the refining of molten iron, the tempering of thousands of tempers, and the formation of the standard, every process can not be missed. In the final analysis, the most difficult process to create high-grade steel is to collect the stone, which is very rare and hard to come by. ”

The Tonggu Strait in the south and the Beihai Strait in the north are perennial wars and wars.

The two major straits consume a large amount of high-grade steel every year, which also makes the reserves of stone deposits decline year by year.

There are no new veins of spar in the eastern continent, and there is a serious shortage of raw materials.

"If a new vein is discovered, all problems will be solved. The cold wind sighed.

"Hopefully, new veins will be discovered. Xiao Su smiled indifferently, suddenly thought of the matter of the Seven Killings Sword Technique, and asked, "Brother Feng, you have just broken through the first realm of the Seven Killings Sword Technique, do you have a new understanding of the Seven Killings Sword Technique?"

Han Feng nodded: "Only everyone in the wind system who has a thorough understanding can create the Nine Heavenly Realm of the Seven Killing Sword Technique." The son of the wind, the first of the wind system, lives up to his name. Seven kills and seven kills are decisive, and the analysis of the wind system is unique. “

Han Tianque - the son of the wind of the Eastern Continent!

Su Jinglu thought for a moment and asked softly: "Then how do you understand that the ninth realm of the Seven Killing Sword Technique - no one has no sword and no wind, I heard that the ninth realm can kill people with your mind and kill people silently." ”

"No one, no sword and no wind, I still can't understand what kind of realm it is. Han Feng smiled bitterly: "To achieve this kind of artistic conception, above the realm, it is not much different from the wind system of the son of the wind." ”

"No one, no sword, no wind, but you can kill people silently, unimaginable. Su Jinglu was shocked.

————————————

Seeing that it was getting late, the cold wind turned to a smile and said, "Otherwise, tonight, I will accompany you here to see how you cast the code name Raptor ......"

"The Raptor is the secret weapon of our Five Elements Sect, and it is generally not shown to outsiders. Su Jinglu winked and said mischievously.

"Am I still an outsider, just by virtue of the relationship between the Son of the Wind and the Nine Heavens Xuan God three thousand years ago?"

"Haha, I'm just kidding. Xiao Su Weiran smiled: "Tonight, the code name Raptor to be created is the Windranger No. 3 driven by Yuanshi." Superior stainless steel, seamless welded fuselage structure, Yuanshi driven, full-power power system, all-weather flight, can adapt to the high-altitude environment above 10,000 meters. ”

Su Jinglu looked confident, everything went well, codenamed Raptor was about to be born tonight.

Compared with the previous generation of Wind Speeder, the design scheme codenamed Raptor has the following significant improvements.

1. Flight speed per second: from 50m per second, to 100m per second.

2. Body material: from general stainless steel, improved to special stainless steel, the safety factor and stability are greatly improved.

3. Flight altitude: directly from 3,000 meters to 10,000 meters of atmospheric ionosphere.

Fourth, the driving device: driven by the spar, changed to the stone drive, the power system has undergone qualitative changes.
