After scalding a large number of ants, Chen Feng decided to inspect it to see if there was any possibility of repairing the mountain.

As a result, there was little hope, and this mutated anteater was so stubborn that it was very persistent in digging a huge hole, just to eat a little ant.

Chen Feng was suddenly a little angry, such a good mountain was turned upside down by your mutant anteater, awesome.

Thinking of this, Chen Feng became even more angry, and casually kicked the inner wall of the hole.

As a result, it hurts to kick his feet.

Chen Feng wondered, with his strength and physical fitness, he shouldn't feel pain when he kicked an ordinary stone!

This is already a relatively deep place in the cave wall, and the light is relatively dim, Chen Feng can't tell what kind of material this is, but what Chen Feng can be sure of is that it is definitely not an ordinary mountain wall stone.

So Chen Feng took Cai Jianxing out of the cave, drilled wood to make a fire, made a torch, and then went in.

Then Chen Feng found an unexpected surprise.

If you guess correctly, the material of the iron-black wall here should be magnetite.

Magnetite is not awesome in iron ore, and it is one of the worse mines in iron ore.

But no matter how bad a mine is, it's a mine!

Chen Feng felt that he seemed to have found a way to upgrade his weapons.

But he is not a professional either, and he is only inferred from the description of high school chemistry knowledge, and whether it is magnetite or not is still to be determined.

After all, real mines are not afraid of fire refining!

Chen Feng gave the mountain a very apt name: Qiangbing Mountain.

With excellent weapons, the combat effectiveness of his subordinates will definitely go up a notch, isn't this a strong soldier?

At night, he made a soup of the mutant anteater, Chen Feng distributed a bowl of soup to each of his subordinates, and took extra care of the strong young guy, and each person had an extra piece of meat from the mutated anteater in the bowl.

Chen Feng just hopes that a few more mutants can be created.

However, it still backfired, and there were no mutants around.

Chen Feng already knew this in his heart, and he didn't have much hope, so the psychological gap was actually okay.

Chen Feng got up early and changed his sleeping habit of sleeping until the sunshine.

He really wanted to know if it was magnetite.

Chen Feng first asked Cai Jianxing to knock down a few pieces with his ultimate, and he wanted to do an experiment.

I have to say that Cai Jianxian's claws are quite awesome and quite sharp, although they only have thirty seconds of use a day.

Cai Jianxing successfully grabbed a lot of "magnetite" and put them into an ugly basket woven of rattan.

He grabbed two baskets and placed them on the ground.

Of course, before that, it is necessary to build a simple iron-making furnace.

The iron-making guy must be hot enough to maximize the energy of the flame.

Like the torches that are usually used to make fires, the energy is so dissipative that there is not much heat to really use.

Usually it is more than enough to make a fire to barbecue meat and boil water, and iron smelting is absolutely not qualified, this level of heat, at best, can only burn the iron red, absolutely not burned.

Therefore, a simple iron-making furnace must be built!

Chen Feng has a little brain pain, and Chen Feng has a little experience in other things, but he has no experience in this iron-making furnace.

In the countryside in these years, there are still a few blacksmiths who make iron, but there are really few villages that make iron.

The point is, not every village has a mine!

Chen Feng sat on the ground, slowly imagining the blueprint in his mind. The process was painful because there was no help from any past experience and experience.

But Chen Feng firmly believes that he can do it, and he is not making a mushroom cloud weapon, as long as he thinks more and ponders more, and is not afraid of failure, then he will definitely be able to do it!

In fact, we can refer to the previous experience of making pottery pots, but the temperature requirements will be higher.

After Chen Feng made a draft in his heart, he began to try.

Chen Feng called Cai Jianxing and asked him to dig a round pit that was neither deep nor shallow in the clearing, and then pile up moist clay at the edge of the pit.

It's just that the thickness and height of the clay are better than those of the previous fired ceramics. After all, the temperature of ironmaking must not be low, and if the preliminary preparations are not done well, it will even crack directly.

Cai Jianyi squatted on the ground, his hands were full of yellow clay, and according to Chen Feng's command, he kept piling up on the ground.

“pia！”

No, it's too thin, just this thickness, it is estimated that it will crack after a while!

Cai Jianxian, this guy is definitely lazy, even if he piles up clay, he will cut corners, and as a result, he will be slapped by Chen Feng.

Chen Feng whipped Cai Health a few more times before this guy became honest and obediently piled up clay.

Looking at the thick and tall clay, Chen Feng nodded, it seemed to be a little different.

You have to poke a few holes in the middle, just like the last time you burned the clay pot, and try to gather the energy of the flames.

Then it's calcination, and that's when the pit comes in handy.

The main purpose of this pit is to make iron, however, it can also be burned by the way to make the clay quickly form.

Chen Feng even asked Cai Jianxing to hold a bamboo fan at the mouth of the stove, which could make the stove more vigorous.

This action attracted bursts of ridicule from the onlookers of the female monkeys, after all, Cai Jianyi is the king of the harem in the monkey group, and he usually fanned him with a group of beauties, but now he is so hard to fan himself.

Cai Jianxing felt a little ashamed and embarrassed, but this was a task given by the boss, not to mention that the boss was watching him from the sidelines, and he didn't dare to play tricks anymore after being whipped.

Chen Feng is also happy to see this scene, he should take care of this kid, so as not to get too carried away.

Cai Jianxing only squatted for a while, and his body was a little shaky, obviously unstable.

"pia~" Chen Feng rewarded Cai Health Care with a whip again.

"Whew. "Is it okay to squat steadily? What about your next plate?

Cai Jianxing had no choice but to continue to squat with a bitter face, and the thick black smoke hit his face, making Cai Jianxing's already dark face even darker.

After an hour, a simple iron-making furnace was built, which was similar to the furnace of the previous kiln, but with some improvements.

The difference lies in the mobilization of flame energy and the improvement of the furnace's endurance.

This iron-making furnace can concentrate the power of the flame more evenly, and the heat can be more evenly radiated to the iron ore to be smelted.

At the same time, because of the concentration of flame energy, it is also a test for the material of the ironmaking furnace.

Chen Feng couldn't find a better material, so he could only pile it up with the amount, and make it thicker, which would definitely be more resistant.

However, the manufacture of the iron-making furnace was only the first step, and then it was enclosed with stones and bricks and a building was built to protect it.

After all, the iron-making furnace is a long-term development, not a one-shot deal, and it still needs to be protected.

Otherwise, it will break down soon, because this thing is a shoddy thing to be precise, and it is not durable.
