After Chen Feng calmed down, he began to analyze the pros and cons of the mutated Rafflesia.

The good thing is that it attracts most of the bugs you hate!

The downside is that this thing stinks so badly that it's really hard to put on!

In the end, Chen Feng still retracted the idea of using mutated Rafflesia, preferring to have more bugs at home, and would rather smoke tobacco and use pitcher plants than put a Rafflesia next to it.

A few days later, Cai Jianxing came over and told him: Iron, enough!

Chen Feng jumped up suddenly, finally enough!

The iron extracted before was used by Chen Feng to make assembly line tools, and he did not make any tools that were of substantial help.

So, strictly speaking, this time, it's a real tool!

On the question of what to build, Chen Feng had a plan in his heart, but now, he is just going through a process of putting it into practice.

"Whew~" (Great health care, get me a basket of clay!)

The flames soon rose from under the blast furnace, and Chen Feng found that with the proficiency and improvement of the little monkeys' skills, the flames seemed to become more condensed.

On the flames, there was even a hint of cyan rising! Chen Feng didn't quite believe in the word perfect fire before.

The blue and cyan flames have been seen by Chen Feng, on the liquefied gas stove, but on the earthen stove in the countryside, Chen Feng has never seen it.

Because the energy of the flame is related to the spectrum!

To put it simply, red, orange, yellow, green, blue, purple, the energy gradually increases from left to right.

Red light has less energy than orange light, and blue light has less energy than purple light.

And what is less energy than red light is infrared, and what is not visible to the naked eye is more than purple energy, which is ultraviolet rays, which is still invisible to the naked eye.

The transparent part of the flame is transparent (infrared) or dark red, indicating that the energy of plasma radiation there is not very high, and therefore the temperature of the radiation is not very high.

The inner flame is orange-yellow, so the plasma radiation has more energy than the flame center, so the temperature is higher. The outer flame is blue-purple or transparent (ultraviolet), indicating that the plasma energy is the highest and the temperature of the radiation is the highest.

Because the liquefied gas integrated stove burns natural gas, and because the structure design is quite reasonable, it can easily burst out of powerful energy, and it is not surprising that the flame is blue.

Due to the structure and fuel of the rural earthen stove, the energy to burn is not strong, so the flame is usually red and yellow.

And Chen Feng's flame here actually has a trace of cyan, which is really commendable.

This means that the temperature of this flame is quite high!

The hard-mined magnetite is carefully poured into the blast furnace and some calcium carbonate is added.

After a while, the iron was baked.

But that's just the first step, it's all about molten iron!

The potholed iron was poured into the blast furnace again, and this time, the younger brothers did their best.

The bellows were all pulled by the small ones and trembled, as if they were about to fall apart at any time.

The flame changed from a slight cyan to a semi-cyan color, which is enough to show the high temperature of the flame.

Chen Feng stood up with his feet propped up, and his two tiger eyes looked down from a high place.

The iron lump inside has been burned, and there is already a slight tendency to transform into liquid, as long as this temperature is maintained for a long time, there is no worry that the iron will not melt away!

Come on, work hard to twitch! Chen Feng silently cheered for the younger brothers in his heart.

After pulling the bellows for ten minutes, the little monkey gradually got a little tired, and the frequency of pulling became significantly smaller.

Chen Feng made a decision immediately and replaced two energetic younger brothers.

The flames immediately returned to their surging form......

The iron in the blast furnace resisted stubbornly, and did not seem to be willing to turn into liquid.

However, the cyan flame was like a parasite, unrelenting in its entanglement.

While the cyan flame wasn't enough to melt the iron easily, it was only a matter of time before it melted.

Gradually, the volume of the black iron block became smaller and smaller, and the amount of iron in it also increased.

Two younger brothers, one holding the bellows, and the other is exerting all the output of the bellows, so that the bellows are squeaking.

On the other side, Cai Jianxing was not idle, at this moment, he was making a mold with clay according to Chen Feng's instructions.

When he found that the plan of firing iron juice was feasible, Chen Feng decided to use the mold method.

Pour the molten iron directly into the mold and wait for the molten iron to solidify naturally, and the thing is done.

Chen Feng believes that the hammering method and the mold method have their own benefits, and there is no difference between the two.

To make something bigger and rougher, it must be a little more cost-effective to use the tempering method.

For example, your own hammers, hoes, and chisels are all rough things, and you can probably get a shape, and as for the hammer, it is essentially a cylindrical iron lump, as long as you make a rough shape, you can use it to knock it.

However, when it comes to fine operations, the mold method still works.

It's like the arrow I'm going to make now, which is a more refined thing.

If you smash it with a hammer, it is estimated that it will not be good for a lifetime, but it will be much easier to make it into iron juice and put it in a mold.

This time, the amount of iron is not much, but it is more than enough to make a few arrows.

Finally, the iron in the blast furnace has all turned into iron juice, and it's time to show the real technique!

Chen Feng ordered Cai Health Care to open the blast furnace, and the characteristics of the water flowing to a low place were revealed, and the iron juice slowly remained downward, dripping like a liquid into the clay mold placed below.

The iron juice flowed slowly inside the mold, and soon filled the entire mold.

So Chen Feng changed another mold, and just went back and forth, and Chen Feng got a total of twelve arrows.

The iron juice lost its scorching heat from the powerful flame and quickly cooled down.

Chen Feng looked at these arrows that shone with a cold light, and his heart was dark!

I was able to create a primitive iron refrigeration weapon, which is simply awesome!

Let me pretend to be a fork will be waist......

As for the little brothers who pulled the bellows, they had long been lying motionless on the ground, and they were really tired!

Chen Feng is very satisfied with the performance of these little monkeys, very diligent, very hardworking, and a good employee!

After the arrows had completely cooled down, Chen Feng asked Cai to smash the clay that had turned into ceramics, and the arrows inside were freshly baked.

Of course, the arrows are blunt, not sharp at all, and don't seem to be lethal.

But these are just small problems, and if you process it a little more, grind it a little more, and it will soon become sharp and sharp, an absolute beast-killing weapon!

The arrowhead designed by Chen Feng is recessed behind the buttocks, and it can be directly put on the wooden arrowhead like a matryoshka doll later.

Finally, it was processed by Qin Wolf's mouth, and when he bit it with his teeth, the arrow was firmly encircled on the wooden arrow like a tight spell.
