Coming out of the cell, Ye Feng was ready to ignore this for the time being, anyway, there were subordinates to take care of these things, what he had to do was to get the iron weapon out as soon as possible.

The melting point of copper is 1083 degrees, while the melting point of iron is 1538 degrees, a difference of 455 degrees, so the original copper kiln could not smelt iron ore at all.

Therefore, a furnace with a higher temperature had to be redesigned.

This is also the reason why Ye Feng did not want Liu Junting to rebuild the copper kiln.

If you want to build a furnace that can smelt iron ore, this problem comes.

Ye Feng has never touched this thing, so he won't get it!

His face was flushed with suffocation, and he immediately felt a headache.

In the end, he was so helpless that he had to gather the people of the pottery burning team and the smelting team to discuss how to build this kiln.

Although they don't understand it, at least in the whole tribe, there is no one who knows more about furnaces than they do.

This can be regarded as crossing the river by feeling the stones.

In the end, after five days of discussion and deliberation, they finally made a prototype wrong.

"Ye Feng, what should we do next?" Looking at the newly built furnace, a clansman spoke.

Ye Feng rubbed his chin, and now there is no thermometer, and the furnace temperature inside can't be measured, so he can only take the copper ore to try it.

So he said to the clansman, "Then hurry up and bring the ore from our docks!" ”

Out of the need for secrecy, Ye Feng never mentioned this iron ore from beginning to end, only saying that he wanted to use a furnace with a higher temperature.

When the clansman heard this, he only thought that Ye Feng was talking about copper mines, so he didn't think much about it, nodded and ran away.

However, after a while, he ran back in frustration and hurriedly said, "Ye Feng, they just won't let me take the ore away!" ”

Ye Feng was stunned for a moment and said, "They? Who are they? ”

As if he had been greatly wronged, the clansman swallowed his throat and said, "That's it...... It is...... There were a lot of soldiers around the ship, and when I was going to get that ore, they were urging me to get out! ”

"Soldiers?" Ye Feng looked stunned.

The clansman nodded very convincingly, and said, "They also said that only Ye Feng can you go and get it!" ”

Ye Feng came to the small boat with a confused face, and really found that there were several soldiers guarding here.

When the soldiers saw Ye Feng, they immediately straightened their bodies, and hurriedly clenched their fists and said, "Marshal!" ”

Ye Feng nodded, also returned the salute with a fist, and said, "Who sent you?" ”

One of the soldiers hurriedly replied: "Report to the marshal, it's the chief, he said that the things here are very important, let us take care of them!" ”

Ye Feng realized that he was one of the few people who knew about this iron ore, and he also knew the importance of iron ore very well, so it was not surprising that he sent some soldiers over to guard it.

At this point, you actually think more thoughtfully.

So Ye Feng said: "You guys are just right here, bring these ores and go to the copper kiln." ”

These soldiers looked at each other suspiciously, and hurriedly clenched their fists and said, "Yes!" ”

The iron ore brought back this time was not much, only a few hundred catties, and they could carry dozens of catties on their backs.

When these ores appeared in front of the eyes of everyone in the smelting team, they couldn't help but be shocked.

"Ye Feng, what is this?" A person hurriedly stepped forward and asked.

The appearance of these ores is completely different from the image of copper ore in their minds.

Ye Feng said: "Don't worry about this for now, let's open the kiln!" ”

After speaking, Ye Feng turned around again and hurriedly stopped the soldiers who were about to leave. "A few of you stay first, and if anyone comes to watch, stay away!"

The doubts on the faces of these soldiers were even deeper, but they still hurriedly followed Ye Feng's orders.

According to the old custom, the tribesmen got the iron ore into the furnace.

The furnace burned for a day and a night.

During this period, Ye Feng was the most nervous person, and he didn't even have time to eat, if someone hadn't reminded him, it was estimated that he would have fainted by the furnace with hunger.

As soon as the sky was hazy, Ye Feng felt that it was time to open the kiln.

"Are you ready?" Ye Feng frowned and said with a serious face.

Underneath the discharge port, a mold for an iron ingot has been prepared.

When the clansmen heard this, they all nodded and shouted in unison, "Ready!" ”

Seeing Ye Feng's nervous expression, they realized that this ore they had never seen before was definitely not ordinary, and they also became nervous with him.

"Open the kiln now!"

Ye Feng frowned tightly and shouted.

One of the clansmen picked up the copper tongs, walked to the outlet, and gently pulled out the stones blocking the entrance.

Everyone's hearts were pounding, if they couldn't produce the material, then it would mean that the smelting had failed, and they would have to redesign the furnace.

One second.

Two seconds.

Three seconds.

There is no red molten iron flowing out of the discharge port.

Ye Feng clenched his fists, and his tightly knit brows were about to be made into a deep Sichuan character.

Just when he was about to break out in a cold sweat, the dazzlingly red molten iron with extremely high temperature finally flowed out along the groove of the discharge port, and flowed all the way to the ironclad mold.

"Good!"

Seeing such a scene, he cheered with relief, and instantly applauded enthusiastically.

Ye Feng exhaled deeply, his face full of joy that could not stop for a while.

The excited clansmen instantly gathered around and hurriedly said, "Ye Feng, what kind of ore is this?" ”

Ye Feng was in a good mood, and he didn't keep this secret too much, but only mentioned it slightly: "Don't ask too much, this is the top secret of our tribe in the future, you just need to know that this thing is definitely better than bronze!" ”

Although they didn't fully know what it was, they were already very happy, and the question had been lingering in their minds for the past few days, since the redesign of the furnace, not to mention how uncomfortable it was.

When the temperature of this iron ingot dropped, Ye Feng stroked it contentedly.

hugged it and found that this thing was quite heavy, but this yield was not easy to calculate, because before smelting the iron ore, Ye Feng forgot to weigh these ores.

Ye Feng couldn't help but scratch his hair in distress, but compared to successfully getting the iron weapon out, there was nothing else.

After stroking it like a treasure for a while, Ye Feng couldn't put it down and handed it to everyone, saying: "You must keep this properly, if you lose it, I will ask you, understand?" ”

These clansmen nodded hurriedly, no need for Ye Feng to say, they also knew the importance of this thing.

Ye Feng returned to the cave, and immediately felt as if he had just soaked in a hot spring, and he was extremely comfortable.
