After the graphite tong pot clamp was done, Wang Tian took the tong pot and let the two adult primitives practice repeatedly.

First, open the fixture

Second, align the tongs pot

Third, afterburner fixation,

Fourth, lift and pour.

The operation of the last two steps must be rapid, cautious and accurate, and the cooperation between the two must be tacit, because the surface temperature of the graphite tong pot at this time has reached more than 1,500 degrees, Wang Tian does not know how long the clamp made of bamboo can withstand such high temperatures.

If the axe is not done, it can be restarted, and if a person is injured, the gain outweighs the loss.

In addition, the strength of the two people clamping the tong pot also needs to be grasped well, not too hard, otherwise the tong pot will be broken at once, and you can also see the iron tree silver flower on the ground.

Wang Tian carefully explained the operation process in detail, and then asked the sunspot to explain it carefully to the two of them, and after confirming that it was correct, he asked them to continue to practice proficiently.

Wang Tian coated the clamp Ω mouth with a layer of mud with plant fibers, put it on the fire to solidify, and then took it to the two of them to practice again, until the operation of the two was smooth and cooperative.

As time passed, the smoke on the charcoal kiln finally stopped, which indicates that the charcoal has been burned.

Wang Tian called everyone to remove the stone shell of the charcoal kiln and knock it down, except for the most side and the bottom, all the other wood turned into charcoal, which was harder than the "flint" formed after the fire was completely burned, and retained more wood fibers.

Everything is ready, you can start smelting, Wang Tian put the graphite tong pot into the stove, add wood to burn, until the inner wall of the tong pot begins to redden, pull out the firewood under the stove and add the charcoal just fired, and then pull the blower, the air flow from the blower blows the charcoal red, and the blue flame rises in the stove.

The molten iron material that had been placed on the pottery kiln is removed and clamped into the graphite tong pot, and the blower is continuously pulled to fully burn the flame and raise the temperature in the stove.

Wang Tian suddenly remembered that even if there was less material for casting the axe, leaving a little material for casting two sewing needles could still be even.

He immediately called Kuroko over and told him to continue pulling the blower, while he made a mold of five sewing needles with mud, and put it to dry by the fire and set it aside.

At this time, the sky has gradually darkened,

In autumn, the hours of daylight are very short, and it gets dark after about half past five.

The iron in the smelting furnace has turned red, Wang Tian increased the amount of charcoal to put in, the blower rotated rapidly, and the iron in the tong pot has begun to melt gradually.

Wang Tian wrapped both ends of the clamp with wet mud, and let the two adult primitives practice again, telling them that if there was danger during backfilling, the two of them would throw the molten iron in one direction at the same time, and the daughter should not panic.

After ten or so minutes, all the iron in the tong pot had been turned into molten iron, and Wang Tian was ready to start casting, when Wu led the leader of the boss, the second brother of King Kong and the thin head of Tuo and other tribes came.

"Son of heaven, it's getting dark, you have to go back!" Wu glanced at the molten iron in the furnace and reminded.

Wu was amazed at the molten iron that had been burned into a liquid state. He couldn't understand why the stones placed on the fire could not become like water no matter how they burned. And this thing, which the Son of Heaven called iron, can.

Wu asked Wang Tian the reason, and Wang Tian picked up a piece of charcoal and pointed to the blower. Wu then discovered that the fire of iron-making was different from usual.

The charcoal flame blown by the blower is so beautiful, but it seems to make people feel scared. Standing on the sidelines, it is natural to feel the power of the flames, which seem to be lava that can devour everything. It's not surprising that it can melt iron into molten iron.

"Wu, it's okay for a while, you let people get out of the way, I'm afraid of danger!" Wang Tian pointed to the red molten iron and said.

After Wang Tian told the two operators again, he picked up a thick wooden stick and hit the wall of the smelting stove from the inside to the outside, and after two or three times, a piece of the stove fell off, and after three times, the tongs pot that was burned red appeared in front of everyone's eyes.

Wang Tian led everyone to retreat ten meters away, signaling that the two adult primitives could operate.

These two people have a big palm and a sturdy muscular man, so let's call him Big Hand first!

The other hands hung down over his knees, this was the emperor's destiny according to some words, and Wang Tian decided to call him Liu Bei.

The big hand discussed with Liu Bei, took the clamp and came to the tongs pot, after standing still one by one, he quickly picked up the tongs pot and came to the model that had been placed in advance, and carefully tilted the tongs to pour the molten iron into the model, at this time, the part of the tongs clamp coated with wet mud had already risen water vapor, and the Ω mouth of the graphite tongs was filled with light smoke.

Seeing that it was almost over, Wang Tian walked up quickly, and asked the two of them to pour the rest into the five sewing needle molds, and after the five sewing needles were ready, they poured all the remaining into the axe molds.

After putting down the tongs pot, Wang Tian looked at the clamp, the mud on the clamp had been burned red, Wang Tian picked it up and tried to clamp a wooden stake, and after exerting dozens of breaths, the clamp broke in response. It seems that such a fixture is still relatively reluctant.

The people of the tribe gathered around and watched as the reddish molten iron in the axe model gradually turned black. Wang Tian picked up the stones, smashed the model, and used a wooden stick to pick up the forged axe. A few bamboo tubes of water were fetched and the water was aimed at the axe at the same time and poured down.

In a burst of ...... After the sound, Wang Tian walked out of the mist, and under the surprised gaze of everyone, he once again brought water and poured it on the axe, until the axe no longer made a sizzling sound, and then poured the remaining water on the five sewing needles.

Wu had already picked up the axe and examined it carefully, it was well made, the shape of this axe was perfect, and the smiling blade had a beautiful arc.

Wang Tian smiled and took the axe handed over by Wu, and put it in his hand to pad it, the weight was lighter than Wang Tian estimated, but it was enough to use.

He found a wooden stick, knocked out the mud in the handle hole, and handed it to the second brother of King Kong.

Wang Tian chose a wooden stick that was hard and strong, peeled it and sharpened one end. He took the axe that had been turned around in the middle of the tribe, and handed it to the second brother of King Kong again with the sharpened handle. He motioned for him to put the handle on, and after the second brother came to the river, found a smooth stone and sharpened it.

Wang Tian walked to the side and put away the five sewing needles, and looked at it to see that it was not bad, and it could be used after a little polishing. In this way, there are tools for sewing hides.

Wang Tian walked behind the second brother of Jin Gang, patted him on the shoulder, pointed to the top of his head, and motioned for him to grind again after he went back.
