The furnace is functioning normally, and only a small number of people are needed to keep it running.

At the high temperature of the furnace fire, the impurities in the iron sand turn into slag, which is removed from the iron sand and falls to the bottom of the furnace.

When the dregs accumulate to a certain extent, there are immediately cleaners who go up to transport the dregs out and clean them up.

Soon after, pieces of pig iron were taken out of the furnace, and the Yilin people, who had been waiting for a long time, placed the red-hot pig iron on the hammering stone pier prepared in advance, and began to strike the iron.

One hammer, two hammers, three hammers......

As the hammer fell, the red-hot pig iron was squeezed and deformed, and it can be seen that there were some impurities that were not completely burned out, which were squeezed out with the hammering.

The process of striking iron is a process of increasing the density of pig iron, and when the density of iron reaches a certain level, it becomes steel that is not easy to break.

If there are too many carbon impurities in the iron, it is easy to break, and only the fewer impurities, the higher the toughness!

Hammer after hammer, the chaotic sound of striking iron sounded together, like a high-pitched song played by laborers.

Xiao Ning looked at this scene and was very satisfied.

"Here, I'll leave it to you, I'll go back to the clan first. Seeing that the scene had stabilized, Yi Lin Feng prepared to go back first.

There must not be a ruler in the Ilyin clan for a long time, otherwise it may cause chaos.

"Leave it to me, go back. Xiao Ning smiled and nodded.

On this day, Xiao Ning and the others had created a total of one hundred iron spears.

This data is quite optimistic, because in fact, they can only be regarded as spending half a day, and some time ago, they were still adjusting the furnace.

The next day, the time came to really test the efficiency, and every Yilin was shirtless and in full swing.

Although it has just passed the cold winter, the weather is still cold, but despite this, every man of the Yilin tribe is still covered in sweat, which shows how hard they work.

Xiao Ning felt that if he threw them into the water at this time, it would probably make the same sound as red-hot iron.

"One, two, three......"

"Fifty-one, fifty-two......"

"One Hundred and Seven, One Hundred and Eight......"

After the sun set, Xiao Ning began to count today's achievements, and when he counted the last iron spear, the audience was boiling and cheering.

The number of this last iron spear is two hundred and seventeen!

This means that today and one day, they have tempered two hundred and seventeen iron spears!

That's a very optimistic number!

Then the proficiency of the people in the back will increase, and the efficiency of striking iron will be much faster, and at that time, it will be far more than two hundred and seventeen, and it may even hit the daily output of three hundred!

This night, Xiao Ning fell asleep with a smile, and woke up with a smile the next morning.

The days passed, and Xiao Ning and the others had stayed in this iron placer mine for almost a month.

In the past month, the enthusiasm of the Yilin people has decreased, and at the peak of the month, the daily output reached 280 handfuls, but now, the daily output is only 210 handfuls.

Although this is also a normal number, the decrease from 280 to 210 does not seem to be an optimistic change.

Xiao Ning felt that he had to cheer everyone up.

No matter how beautiful the scenery is, you will get tired of staying for a long time, let alone this boring iron placer mine?

Xiao Ning looked at the people who were working, and wondered in his heart, why not do you want to do a team building?

Instill some chicken soup! Like these Yilin people, it should be easy to fool, right? It's easy to be driven by chicken soup, right?

After all, they don't know so many routines, unlike modern people, who are immune to chicken soup for the soul, and even scoff at it.

Xiao Ning discussed it with Jiang Fei and felt that this matter was feasible!

So, Xiao Ning planned to hold a speech two days later to brainwash everyone.

Xiao Ning and Jiang Fei left the iron placer mine temporarily, and they were going to find some materials to enrich Xiao Ning's lecture.

"That fruit tree is good! It can still bear fruit on a cold day, what kind of fruit is this?" Jiang Fei said, pointing to a tree not far away.

"Go over and see. ”

Xiao Ning and Jiang Fei came to this tree, this tree is not thick, it is the thickness of an adult's arm, but its treetops are full of fruits.

The fruits are bright red and look like strawberries, but they are bare, and the skin resembles the skin of a shiny apple, which is very attractive.

Jiang Fei reached out and picked one, wiped it casually with his clothes, and was about to eat it in his mouth, but was slapped off by Xiao Ning.

"You're stupid! I don't know if it's poisonous, so you're going to eat it!"

"Have you forgotten the scene where you ate poisonous mushrooms and saw the elves?" Xiao Ning reminded.

Jiang Fei's face suddenly fell, Xiao Ning really couldn't open any pot, and he turned out the old story of eating poisonous mushrooms.

"If you don't give it a try, how do you know it's not poisonous?" Jiang Fei said.

"Then you can't test the poison yourself, right? If it's really poisonous, won't you burp?" Xiao Ning said.

"Then you eat?" Jiang Fei picked up the fruit that fell to the ground and stuffed it in front of Xiao Ning.

"Roll the calf!" Xiao Ning glanced at Jiang Fei and gave him a roll of his eyes.

"You take a few with you first, and then see if you can get any animals, and feed them to test the poison. Xiao Ning said.

"You're so cruel. Jiang Fei shook his head.

"Then you try?" Xiao Ning glanced at Jiang Fei.

Jiang Fei immediately shook his head like a rattle.

"This fruit should be poisonous, if it is not poisonous, it cannot grow so well, there are no moths on it. ”

"If it's not poisonous, there should be birds and insects to eat it. Xiao Ning inferred.

"It seems to make some sense. Jiang Fei nodded approvingly.

"Let's go. Xiao Ning beckoned.

The two were about to leave, but Xiao Ning suddenly stopped again, because he seemed to hear some people talking.

"Did you hear that?" asked Xiao Ning.

"What did you hear?" Jiang Fei was stunned for a moment, Xiao Ning suddenly stopped, which already made him feel strange, and now that Xiao Ning said this, he was even more confused.

Where did the sound come from?

"Didn't you hear someone talking?" Xiao Ning asked again.

"I didn't hear that. Jiang Fei shook his head.

However, it didn't take long for Jiang Fei to frown, and it seemed that there was really a conversation!

"It seems to be there!" Jiang Fei pointed to the back of the fruit tree.

Behind the fruit tree, there is a small high slope, and the sound seems to come from the back of the small high slope!

Xiao Ning approached Xiao Gaopo and listened carefully for a while, because the opposite side was speaking the indigenous language on the desert island, Xiao Ning could not fully understand.

However, he still understood some scattered words, and through the association before and after, Xiao Ning's face changed slightly.

The person on the other side seems to be eyeing his iron ore!
