The cooperation between Xiao Ning and Zheng Cheng was declared to have collapsed, and after Zheng Cheng left, Xiao Ning closed himself off for three days.

Three days later, I went to find Yilin Feng, I don't know what to say, and the next day the two left the Yilin tribe with hundreds of strong men of the Yilin tribe.

"It's been four days, Xiao Ning and they have been gone for four days, where have they gone?"

Chen Ling looked at the direction of Xiao Ning's house, propped his head, and his face was full of sadness.

"Maybe it's some secret thing, the less people know about it, the better. Chen Xue said, her eyes were also full of worry.

"Don't worry, Feizi's life is big, so many difficulties have been overcome, nothing can stump him, it will be fine. Jiang Fei put a strangely shaped fruit into his mouth and said vaguely while chewing.

"Yes, Captain Xiao Ning will be fine. Tong Yiyi also said.

"If you have a big heart, you know how to eat!" Chen Ling threw the fruit on Jiang Fei's face, and the purple fruit exploded directly, and the purple juice splashed all over Jiang Fei's face.

Jiang Fei wiped the juice off his face with his hand, and glared at Chen Ling with a dark face.

"Jiang Fei is right, now there is no leader in the Yilin clan, because of our relationship with Xiao Ning, many Yilin people are watching us, we can't panic. ”

"Once we show panic, it's likely to affect them. Chen Xue said.

"Alas, Xiao Ning, come back quickly. Chen Xue leaned on the table and muttered.

Another three days passed, and Xiao Ning and the others still had no news, as if they had disappeared.

On the tenth day, Chen Ling and the others were a little breathless, but they didn't know where to find Xiao Ning.

So, they just have to keep waiting!

On the fifteenth day, finally, news came!

One of the Illin tribesmen who had followed Xiao Ning and them out brought back a bag of gravel-like things.

"What about Xiao Ning, what about them?" Chen Xue asked, looking at the Yilin clansman.

"Elder Xiao Ning and Patriarch Yilin Feng have discovered iron placer, and we need people to go there to smelt iron. The Irin replied.

Chen Ling and the others widened their eyes, it turned out that Xiao Ning had gone to look for iron ore!

What is the use of iron ore, of course they know, can make a lot of things, pots, bowls, knives and so on.

And most importantly, to be able to craft weapons!

The weapons used by most of the Irin were stone spears, a wooden stick with a sharpened stone tied to it.

Xiao Ning's goal is to turn everyone's spears into iron spears!

Although Xiao Ning also discovered an iron ore before, the iron content in it was not high, and it had been mined, and the mined iron was refined into hoes for farming.

Chen Ling took the bag from the hand of the Yilin tribesman and grabbed a handful of sand inside, these sand and gravel were not ordinary sand and gravel, faintly shining with metallic luster, more like small iron balls!

This is the iron sand produced in the iron placer mine!

"How many people did Xiao Ning let you bring?" asked Chen Xue.

"Elder Xiao Ning said, please Jiang Fei over, and I will take a thousand people with me. Said the Ilin who had been sent back.

"Let me go?" Jiang Fei was a little surprised, he didn't expect Xiao Ning to bring him this time, it was really the sun coming out in the west.

"Okay! no problem!" Jiang Fei nodded.

Soon, a large army of a thousand men was ready to go, they brought with them all sorts of tools, and there was enough food and water.

From here to the iron placer, it takes about eight days to set off for a large group, and only six days to walk alone.

In addition to the 1,000 people who have already set off, half a month later, another group of 100 people will set off for the iron placer mine.

The people who were sent back by Xiao Ning had already left a map for those who came after him to find the location of the placer mine.

The 100 people who set out after this will carry enough food rations for 1,500 people to last for half a month.

When these 100 people set off, Xiao Ning's side will also send 100 people to turn back, and if there is no accident, the two teams of 100 people will meet on the fourth day.

Such an arrangement can allow Xiao Ning and them to get food security.

It can be said that Xiao Ning is very thoughtful.

After walking for eight days, Jiang Fei finally met Xiao Ning.

"The temperature here seems to be a little higher than other places!"

Jiang Feifei walked on the iron sand, feeling bursts of heat surrounding his body.

"When the sun is at its strongest, the iron sand absorbs the temperature, and when the temperature gradually decreases, the hotter iron sand will make people feel that the temperature here is higher than outside. Xiao Ning explained.

Jiang Fei nodded, and as far as the eye could see, the area of this iron placer mine might be five hundred square meters, that is, two hundred and fifty thousand square meters!

It sounds big, but it's actually okay, it's only two kilometers and takes about ten minutes to walk around.

"Do you estimate how many weapons can be refined from the iron sand here?" Jiang Fei asked.

"That's enough for each of the Ilin people to have an iron spear. Xiao Ning speculated.

"This is a big project! 20,000 iron spears, without the assistance of machines, are simply tempered by hand, and they will not be completed in a year and a half. Jiang Fei said.

"Three months, if the progress goes well, two and a half months is enough. Xiao Ning said.

"How is that possible? In three months, even if I count you for a hundred days, that is, you will have to make two hundred iron spears a day, and even if you don't sleep, you will build at least eight iron spears per hour on average!"

"Is it realistic?" Jiang Fei shook his head, not believing that Xiao Ning could complete the production of 20,000 spears in three months.

"What's unrealistic? I'm fifteen hundred!"

"Fifteen hundred people, and you can't make two hundred iron spears in one day?

Jiang Fei scratched his face, it seems that it is also oh, fifteen hundred people, a group of a hundred people, it should not be a problem to hammer out an iron spear in an hour.

If it is divided into fifteen groups, the output of one hour is fifteen, and at the end of the day, after removing the time of ten hours of rest, the remaining fourteen hours can also make two hundred and ten handfuls.

Indeed, two hundred spears a day seems to be a steady batch!

Next, Xiao Ning began to build the furnace, which is essential in the ironmaking process.

There is also charcoal and so on, which are also ready-made goods, but you need to find more wood to make charcoal halfway, otherwise it will not be enough.

Two days later, the furnace was built, and everyone began to act according to the division of labor arranged by Xiao Ning in advance.

One group of people made a fire in the furnace and put charcoal, another group blew wind into the furnace to increase the fire, and the third group began to add iron sand to the furnace.

When it was basically stabilized, only twenty people were left to guard the furnace, and the rest of the people were all on standby in groups, ready to strike iron!
