showdown!I enjoy life on the island

After confirming that there were no major problems in the overall process, Xu Le patted the sawdust on his hands and began to prepare for the next thing.

The drying operation of the ventilation furnace is coming to an end, and the fuel in the furnace is gradually exhausted.

The majestic "whoosh" sound became more dull.

The color of the flame column erupting from the upper end of the stove also gradually retreated from the light white bright golden red to the ordinary red heat.

The fluid formed by the vitrification of silicon at the mouth of the furnace condenses, and the black smooth surface can almost reflect the silhouette of a person.

The temperature of the furnace was further reduced, and the outside of the furnace wall was as dry as red bricks.

The new ventilated furnace has a width of only 1.5 meters, a wall thickness of more than ten centimeters, and a strong heat storage capacity.

The base of the stove was dug 1.8 centimeters into the ground, and the height above the ground was more than [-] meters, almost level with the top of Xu Le's head.

Xu Le opened a special hole on the side of the furnace wall for filling, and at the same time built a stone step for going up and down.

There are also openings at the bottom of the furnace for loading fuel and taking out slag, and a thin flame like a sheet of paper leaks through the opening gap.

The entire furnace now occupies more than one-third of the area of ​​the workshop, and the forging table, tool rack and other facilities have also been adjusted in position accordingly.

The upgraded ventilated furnace can not only support higher temperature, but also increase the amount of iron ore smelted in one furnace.

At least double, if you are crazy, it can be more... Xu Le made an estimate silently.

"Let's first fire a furnace of iron and make a large model. When the new charcoal is produced, we can directly reverse the model."

Xu Le explained that after the temperature of the furnace dropped further, the old charcoal was fed from the fuel filling port at the bottom.

Iron ore is placed on top of the charcoal to reignite the flame.

Not long after, the raging fire in the ventilation furnace started to burn again, and white-hot flames spewed out from each hole.

The iron in the iron ore was melted and precipitated under the more intense heat, passing through the layers of charcoal, and falling into the basement that was sunken [-] centimeters down.

The shape of the base has been designed to present the appearance of a funnel to facilitate the collection of molten iron.

In the basement, Xu Le laid clay pots, and all the collected molten iron dripped into the high-temperature-resistant clay pots, and then freely cooled and condensed.

A furnace of iron ore is completely fired and taken out for re-melting.

While waiting for the molten iron to melt, Xu Le took out a sandbox made of thick planks, filled it with sifted dry fine sand, and tamped it down.

The "Power of the Crazy Gorilla" provided tons of physical strength. Xu Le turned into a humanoid pile driver, and the filled sand box could be used as a brick.

Next, blacksmith Xu used the previous method to carve out detailed sand molds, which were larger than the size of the parts he was officially going to make.

This is to leave enough margin for the mold to cool and shrink.

The fineness of the original model determines whether Xu Le can leave the work of repeated casting to the orangutans...so he sculpts with extra care.

Even using the techniques in the ancient bone carving... It's like killing a chicken with a bull's knife.

However, the sand box is as solid as bricks and stones, no skill is needed, and ordinary knife skills can't carve it at all...

Barrage in the live broadcast room——

"Looks like a gun barrel again?"

"Okay, so rough..."

"It's so thick... how powerful it is!"

"No way, lack of firepower phobia, inherent terminal illness, can't be cured, only the equivalent can relieve it."

"This sand mold is too strong, Xu Shen's shoulder strength is outrageous."

"Compared to the time when I made the Lightning Code, the skill has improved again! Could it be that the Lightning Code is Xu Shen's pinnacle work?"

"Xu Shen said that this time you are going to add a turret to the wooden cow and horse?"

"It's on fire! Xu Shen is indeed a loyal believer of my Dabao Tower God Sect!"

"Ancient wooden oxen and horses, carrying heavy artillery, this is the romance of a man!"

"Xu Shen's eyes on Cang Jiao don't seem to be quite right either... Is this the rhythm of building a giant war beast?"

"I went to bed early last night, why did Xu Shen have another battle pet overnight?"

"Brother upstairs, not only do you go to bed early, you also wake up late. Don't you know that the paleosphere has exploded now?"

"Slab-toothed rhinoceros... Xu Shen's transformation of fuel and smelting technology is also related to the discovery of this ancient relic."

"Xu Shen, are you going to start the conquest mode?"

"Rub your hands, rub your hands."

"..."

The molten iron casting was completed, and Xu Le's mold was also made.

High-heat molten iron is injected into the mold, filling the runners, hot air is ejected from the pores, and finally excess molten iron overflows.

Wait for the molten iron to cool and solidify.

At this time, a batch of charcoal cakes fired in the morning has also been carbonized.

Whether it was the pungent smell or the sound of gas tumbling in the charcoal stove, it gradually subsided.

Xu Le sealed the blast inlet and ventilation pipe holes, allowing the furnace to enter a completely sealed state.

"Let's carry out a period of heat preservation and calcination to maintain an oxygen-free state, and at the same time, the unfinished spontaneous combustion inside can also continue.

"Finally, just pour water outside the charcoal stove to cool down."

The old charcoal firing process can be completely left alone, but the new firing process requires full intervention...the trouble is a little trouble, but it is worth the money.

Model casting and charcoal firing, Xu Le's two-line operation, soon advanced to the finishing stage.

The workpiece in the sand box gradually cooled, Xu Le dismantled the wooden frame outside the sand box, picked up the hammer, and smashed the sand mold that was already as hard as a stone.

Small pieces of sand fell off, revealing the dark surface of the inner barrel.

Continue to hammer and clean, and the three gun barrel models and the three mandrels are all stripped out.

One barrel is about the same size as Zhu Lei Dian, and the other is closer to the size of Hu Ju Qingshuang.

The last one obviously exists as the main gun, and its length and thickness are extremely conspicuous. The iron barrel is more than one meter long and has an inner diameter as thick as a forearm.

After remolding and recasting, the size of the official version of the gun barrel will be somewhat reduced, but the overall difference will not be too great.

It is not difficult to imagine how powerful the cannon made of this gun barrel will be when fired.

Clean up the gravel on the surface of the gun tube mold, scrape the small protrusions at the mold clamping position, and the mold is complete!

At the same time, a pleasant reminder sounded——

[Fuel refining skills have been upgraded, the current level is Lv4! 】

()showdown!I enjoy life on the island

Chapter 316 The Fire Is Blue

Skill upgrading means that the firing of charcoal has been completed, and the rest is the harvesting link.

The charcoal fired by the new process has a calorific value close to that of coke, and is ash-free and smoke-free, with excellent performance.

Whether it is used to burn boilers or make iron, it is better than the charcoal obtained by burning a whole piece of wood in a large furnace.

No coal mines have been explored on the island, at least not in a short period of time. This kind of charcoal with excellent performance will be the main fuel for a long time to come.

At the same time, the skills awakened under the previous template, and the derived skills after answering the highest level in the current template, are also awakened——

[Earthwalker's derivative skills have been awakened - overload! 】

This is also a sustainable skill that consumes popularity points, but the target of the effect is not Xu Le himself, but the various tools and weapons he directly controls.

The duration is 5 people's popularity exchanged for one second. Xu Le's current 300 million popularity can support 1 minute of [overload].

During the continuous process, as long as it involves effort, the effect can be doubled within the duration...

You have been strengthened, send it quickly?

For example, I can instantly overload the temperature of the ventilated furnace, reaching a high temperature that cannot be achieved with the current structure alone——

There is a direct relationship between furnace temperature and charging. If there is a lot of charging, the furnace temperature is not easy to rise. The output of one furnace is large, but the cycle is long.

Conversely, less charge and high furnace temperature are exchanging the reduction of output for smelting efficiency.

After [Overload], you can load a large amount of material and maintain high-speed ironmaking.

It is also possible to let the Thunderbolt Dian shoot out the power of the tiger to clear the frost, and maintain the range of the Thunderbolt Dian itself——

Huju Qingshuang is similar to a shotgun, and it needs to stick to the face to exert its maximum power.

One spray can be sprayed for 100 meters, and the power will not drop... Tsk tsk, the picture is beautiful.

This is a skill that can be used for construction or for doing things.

However, [Overload] also needs to pay a price, and the durability of the corresponding tools and weapons will be the same as the blood collapse.

It's not impossible to explode halfway.

That's right...Xu Le squinted his eyes, didn't he still have the [Characteristic Maintenance] skill!

With the combination of these two skills, at least within the duration, the firepower is doubled, and there is no fear of overturning.

Of course, after the skill duration expires, it is inevitable to "[Overload] for a while, repair the crematorium".

Take it easy.

After checking the skills, the new charcoal is released, and the filling of the ventilated furnace starts to be smelted!

This time, Xu Le filled the furnace with nearly [-] kilograms of crushed iron ore at one time.

At the same time, nearly a quarter of the charcoal that has been baked is also put into it.

Then there are auxiliary materials such as limestone, etc., which are put in according to the amount.

Barrage in the live broadcast room——

"It's...it's so full!"

"Xu Shen's smelting volume this time is at least five or six times that of the old furnace!"

"Although the new stove is equipped with new charcoal, the performance has been greatly improved, but Xu Shen is a little too impatient for doing this?"

"With such a large amount of iron ore, it may take half a day just to heat it up."

"Or...Xu Shen intends to work slowly and carefully?"

"Didn't Xu Shen say this morning, this wave is in a hurry, how can you be so leisurely and leisurely?"

"Is it because you are worried about the attack of the adult plate-toothed rhinoceros, and you are a little confused?"

"How is it possible, all the players in Bermuda are messed up, and I promise God that they won't be messed up!"

"Look, Xu Shen must have his own plan."

"Brother Xu Le, come on!"

"..."

ignition!

Xu Le crossed his arms, waited for each piece of charcoal cake to spit out flames, and then activated the skill——

【overload】!

The flames flowed like a liquid, each piece of charcoal cake seemed to disintegrate, and a huge amount of heat exploded out.

In the ventilated furnace, the airflow was violently stirred, and there was a low whimper like a beast's roar.

At the furnace mouth, a pillar of fire rose into the sky, and the hot wind blowing Xu Le's hair back.

When the pillar of fire first spewed out, it was a dull red color, and then it became darker and brighter.

The bright red continued to be dyed with the color of the water friends in the live broadcast room, turning orange-yellow.

The flame color stayed at the level of orange for a while, and then it began to become dazzling and glaring, and began to turn into gold.

The golden color seems to be fading, becoming lighter and lighter, and finally becomes almost pure white!

Barrage in the live broadcast room——

"This temperature... is a bit bluffing!"
