Beginning Backpack [Farming]

After half of the water season, the weather became hotter day by day. Shen Huaijin had to wear a bamboo hat when tending the fields to avoid being burned by the hot sun at noon.

As Li said, the third road was also built soon, so far, the valley, the base, and the coal mine are connected to each other, making it convenient to go back and forth.

According to the agreement earlier in the morning, Shen Huaijin called the orcs in the tribe except for the hunting team that day, and went to the base together.

Mining and smelting are the most basic things. He must ensure that everyone can master them proficiently so as to maximize the efficiency of tribe construction.

The thunder that fell in the rainy season last year split the bare mines, reducing some difficulties for them to mine hematite ore.

Relying on their strength, the orcs smashed the stone tools directly on the exposed ore, but unfortunately it failed several times.Shen Huaijin stood aside and watched for a while, then stopped them, and said calmly, "I have a better way."

He let Li ignite the fire to roast the ore. After the stone was boiled hot, he poured the cool stream water on it. Under the action of heat expansion and contraction, the rock became brittle.Shen Huaijin raised his chin and signaled everyone to try again.

Seeing this, the orcs on the side quickly smashed it again. This time, they smashed the ore easily, and small irregular stones fell to the ground.

"Ho!"

The orcs couldn't help but gasp, Yan immediately asked everyone to follow Shen Huaijin's practice, burn first and then pour, and smash the ore together.

Everyone worked in full swing, and the red stones fell all over the ground. Shen Huaijin picked them up one by one into the rattan basket.Seeing that he was sweating profusely, Yan also came to help, and asked, "Jin, what are these stones for?"

Shen Huaijin showed a mysterious smile, "Yan, after these stones are burned, you will know their uses."

After collecting about five or six baskets, Shen Huaijin asked everyone to stop for a while, and carried the dropped small ore back to the base, and then crushed it.

In the absence of a mill that relies purely on manpower, this operation is time-consuming and labor-intensive. Fortunately, the orcs are so talented that they directly turned their hands into animal claws, barely reducing the difficulty.

Holding the stone tool in his left hand, his right hand turned into a wolf's claw, and he smashed it down with all his strength. The muscles of the upper body bulged like mountains, full of strength and beauty.Under his movements, the originally finely crushed ore gradually turned into powder.

Shen Huaijin squatted on the side, looking up and down following his movements, and suddenly sighed with emotion in a low voice: "Hey, it turns out that orcs can choose to turn only one part into a beast."

He paused sharply, glanced at him calmly, and immediately erected silver erect ears on the top of his head. The ears that had just touched the air were a little sensitive, so they unconsciously moved twice.

Shen Huaijin immediately smiled, and touched the fluffy wolf ears contentedly.

It is not enough to crush and sieve the ore. Limestone as a flux and quartz sand on the bank of the stream are also needed for smelting.Limestone is used to remove slag, while quartz has good fluidity and can carry away slag.

Limestone should also be ground into powder and mixed with quartz sand and ore powder to form raw material powder.

Charcoal and powdered raw materials were stacked into the iron smelting shaft furnace layer by layer. The amount of powdered raw materials was only enough to fill three furnaces, but it was enough for a demonstration.

The pottery pipe connected the air outlet of the bellows to the air inlet of the shaft furnace. After the charcoal in the furnace was ignited, the orcs began to pull up the bellows and continuously blow air into the furnace.

The fire is getting stronger and stronger, and the naked eye can see that it is slowly changing from deep red to orange, indicating that the temperature of the fireworks is constantly rising.

The charcoal in the furnace will gradually decrease during the combustion process. In order to maintain the temperature, charcoal should be added from above in time.Fortunately, they have a lot of charcoal in stock, which is enough to use. Even so, the orcs who are not in charge of blowing the wind for the time being still choose to chop firewood and burn charcoal in preparation for a large amount of iron smelting in the future.

In the furnace that they can't see, many magical and wonderful chemical reactions take place. Iron oxide is reduced to iron by carbon and carbon monoxide, and calcium oxide forms separable calcium salts with various impurities.

Little by little, it was developing in the direction Shen Huaijin expected.

Smelting iron is not like burning pottery, and it cannot be solved in a few hours.Especially their early stage work took a lot of time. Not long after the stove was fired, the sky was dark and the sun was about to set.

It's just that the work of blowing the wind cannot be stopped for a moment, and it is best for the orcs to take turns.After discussion, everyone finally decided to stay at the base until the batch of ore was burned.

Yan also wanted Li Xian to take Shen Huaijin back, thinking that the big witch in the tribe shouldn't work so hard.

Shen Huaijin rejected his kindness, shook his head and said, "Of course I have to watch the iron smelting for the first time in the tribe, and I can tell you some important points immediately, so as to avoid repeated failures in the future. Yan, I can go to the market with me, naturally I am not afraid Stay here for a few days."

This statement is well-founded, and Yan can't refute it.

Everyone is not of Moji's nature, so they immediately picked one orc to go back to report the news, and then divided a small team to go hunting. of shelter.

The orcs who left soon returned with a full load, and everyone lit a bonfire, and roasted the processed animal meat on the fire.

Under the roasting of the tongue of fire, the golden animal oil overflowed and dripped, crackling.

The barbecue without seasoning and the simple shelter from the wind, everything looked like Shen Huaijin had just landed in the wild beast jungle, the difference was that this time around him was full of excitement, so he didn't have to be as nervous as before.

The wind kept blowing, and the orcs had to take turns to eat.

After a whole night of busy work, there was still no visible effect. Everyone didn't dare to think about bad results, but just buried themselves in hard work, sweating profusely.

When dawn broke on the second day, the orc who was blowing the wind let out a "huh", and saw burnt orange-red, magma-like slag slowly flowing out from the slag outlet of the shaft furnace.

Shen Huaijin knew that metals and impurities with low melting points were discharged with the help of quartz, while iron that could not be melted was softened and condensed into lumps, which remained in the middle and lower parts of the shaft furnace.

Shen Huaijin asked everyone to continue pouring charcoal and blowing wind without stopping.

In order to prevent the slag outlet from being blocked, after the hot slag cooled and solidified, Shen Huaijin pushed it away with a stone.

Seeing that everyone wanted to throw the slag aside, he quickly stopped it loudly, "Don't throw it away, this slag is my raw material for making cement!"

Cement production requires grinding limestone and clay, calcining the clinker, and then grinding it into powder with the slag left over from ironmaking. The important slag should not be thrown away as garbage by unsuspecting orcs.

Surprised, the orcs quickly placed the lumpy slag beside the charcoal carefully, waiting for Shen Huaijin's next command.

Everyone has been busy for almost a day and a night, and only took a short nap in the middle. At this time, their faces are a little tired.Seeing this, Shen Huaijin discussed with Yan and asked him to lead a team back to the tribe, and let Lin's team replace them.

Yan also saw that everyone's condition was indeed not very good, so he led the team back without saying much. Rin's team came very quickly, and immediately filled up the previous position.

Leaving aside the blowing orcs for the time being, Shen Huaijin called the remaining orcs together and gave other instructions.

"The clay from the bank of the stream is washed, sifted, dried, ground and calcined with limestone, and the slag is ground into powder, and the two are mixed together to make cement. You put the cement powder here, and I will let Ya The beasts are here to carry it, how about it, can it be done?"

"Yes!" The orcs replied enthusiastically.

Shen Huaijin was taken aback and rubbed her ears.

The charcoal fell, the slag flowed out, and he worked passionately for two more days. Shen Huaijin estimated that the smelting was almost done, so he asked everyone to stop, knocked on the side door, scraped away the unmelted charcoal ash, and smelted the orange-red spongy rough iron The block was pulled out and clamped to a flat stone slab with a stone tool.

A total of three spongy iron blocks were produced from the three furnaces, and they were still a little soft when they were first taken out. Shen Huaijin asked everyone to cut each into two pieces with a stone chisel and a stone hammer, and forged them with a stone hammer.

On the edge of the wrought stone platform, a stove for heating has been burned out of clay, equipped with bellows and pottery pipes, and charcoal is also used as fuel.

When forging a thick iron block, the temperature of the iron block drops rapidly, and it is necessary to put the cooled iron block on the stove from time to time to burn it red hot before continuing to beat it.

The obtained rough iron gradually becomes a flat cuboid under continuous forging, which is the basis for making various iron tools.According to the instructions, the orcs used a stone hammer to make a dent in the middle of the flat iron block, put it in the furnace to soften it, then folded it and beat it in half, repeating it over and over again.

During this process, the spongy chunks of iron gradually compacted, and the impurities and a large amount of carbon in them were also stripped off in the process of "thousands of tempering". The ductility of the iron chunks became stronger and gradually changed to the shape Shen Huaijin needed.

During forging, the iron block is repeatedly heated in charcoal, and a small amount of carbon penetrates into the iron. After repeated forging, the uniformity of carbon gradually improves, and the iron block is forged little by little to become hard and elastic steel.

Under Shen Huaijin's expectation, six iron blocks of different sizes were finally forged into shapes such as short knives, sickles, and hoes.

Weapons and agricultural tools are the bottom line and future of the tribe.

With anticipation and tension, Shen Huaijin sharpened them on the whetstone with everyone.

The edge of the blade was ground a little bit, revealing a dazzling silvery white color, exuding a metallic luster in the sunlight.

This is a kind of sharpness that cannot be achieved with stone tools and bone tools. Everyone exclaimed again and again, and the iron tools kept spreading in the hands of everyone.

Li brandished a dagger, sharp and piercing the wind, and some orcs tentatively picked up a hoe and dug up the tight soil with ease.

Yan rarely showed an excited expression, he rubbed his hands impatiently, eager to try the dagger in Li's hand.After receiving it, he waved it twice, only to feel that there was a fire burning in his chest, and his face was flushed red.

He looked at Shen Huaijin, as if he understood that mysterious smile.

Standing here, Shen Huaijin looked like an observer who had a panoramic view of everything, with complex emotions surging in her heart.

The orcs just exclaimed how easy it is to use iron tools and how difficult it is to forge, but they didn't realize that a new era was coming, and the splendid civilization has been shining since then.

The author has something to say: Xiao Shen jumped over the Bronze Age, cowhide!
