Even if there is not much firewood, this year's wilderness tribe has also achieved the achievement that no one has frozen to death, and the tents where the tribesmen live have braziers, and in the sheepfolds built by brick houses, there are also people who go to make fires every day to keep warm.

"The Purple Flower Tribe sent a message saying that you want to come to the wilderness as a guest in spring?"

Pura rushed into the tent and saw Ana delivering the message at a glance.

"Yes, the patriarch asked us to come over and say hello to the patriarch of the wilderness in advance."

Ana looked at Pula and smiled.

"I'm worried that you don't have enough firewood, so Qianqian also asked us to bring some charcoal."

Really send charcoal in the snow.

"Does Qianqian have a letter for me?"

Hearing the words of the purple flower, the people all cheered for the support of the charcoal fire, and only Pura asked anxiously with Ana.

"Qianqian guessed that you would definitely ask like this, well, this is a letter to you."

Ana's hand reached into her bosom and fumbled with it, handing the triangle-folded letter to Pula, who had plenty of time to write back the day after their departure to-morrow.

Coming and going in winter is very rare, and the people of the wilderness are very curious.

In addition, most of them, the allies who had not yet seen Purple Flower, everyone gathered outside the patriarch's tent, wanting to see the difference between the two clans.

"Precautions for charcoal burning?"

Pura immediately opened the letter, and the main content of the letter was an instruction manual, which included all the points on how to avoid charcoal poisoning, and only said one sentence at the very end.

"I'll follow the wilderness tribe in the spring, are you welcome?"

It was just a few neat handwriting on a blank piece of paper, but Pula seemed to see the girl writing the letter smiling like a fox through the letter.

This guy is definitely plotting against him!

"We have a request, and we hope that the Wilderness Tribe will find a way."

After the greetings were finished and the gifts were finished, Ana finally said the ultimate purpose of the trip.

Pula's eyes flashed, and she knew that charcoal could not be given for free.

"You want to go to the White Rock Tribe?"

Moti don't scratch his head.

Is Purple Flower's target for the White Rock Tribe? What is noteworthy about their tribe?

This time, Pula will be as confused as her old father.

"Yes, as long as we can take our people into the White Rock Tribe and take a look around, there are no other requirements."

Ana smiled harmlessly.

"But ......"

Mortibe hesitated.

"May I ask, what do you want to see when you go to the White Rock Tribe?"

Pula thought to herself, the candidate to infiltrate Baiyan is definitely Jun Qianqian.

"We won't run around in the White Rock Tribe, Zihua doesn't want to steal anything, nor does she want to sabotage, she just wants to see if there is a chance for the two sides to do some business."

Ana quickly explained that he was very innocent, almost like a newborn lamb.

But Pura had already decided in her heart that half of Jun Qianqian's words could be true, and it was all her unprecedentedly conscience discovery.

Pula pouted to herself.

It's just that she can't figure it out, why did Jun Qianqian look at the Baiyan tribe?

If Jun Qianqian answers this question, then she will say that she cares about a lot of things.

"The ore of the White Rock tribe is very important, and in order to ensure the supply of raw materials, we must be prepared to trade everything."

The Purple Flower people gathered at the blacksmith shop at this time, and Jun Qianqian was holding an iron block in her hand, knocking and banging to make a pair of bearings.

A few days ago, she was still eating, and suddenly she had an inspiration:

Since goats can pull plows, they must also be able to pull carts, as long as they make a rickshaw, the long distance can be overcome!

So, today everyone came to the blacksmith shop to watch her and Daze study the animal cart together.

"Will the deal with the White Rock Tribe exchange the weapon?"

There is not much iron sand in Zihua, and in everyone's cognition, weapons are extremely valuable things, and if this can be used to make a deal, everyone feels a trace of determination in their hearts.

"You don't have to be so serious, it's nothing to exchange weapons, just pinch the method of making farm tools and heavy crossbows in your hands, and change the bow and spear."

Bows and spears are easy to make, and since they want to trade ore with the White Rock tribe, they must also teach each other how to make iron, and as long as they can forge them, they can produce both weapons independently.

Of course, Purple Flower will also weigh that for this big business, they must get enough ore.

"The way to make iron must be given."

Daze had the posture of marrying his daughter, and sighed melancholy.

"After all, the people of the mine belong to the mine."

It's not like seeing two magnets in the bazaar, picking up a leak and taking it home cheaply, such a large number of transactions, if the other party does not doubt the value of iron ore, it is really stupid.

Not only that, but limestone is also a good thing.

The cultivated area of purple flower is very large, and after a few years of grain planting, the soil will gradually acidify if the nutrients are insufficient, and quicklime and hydrated lime are good regulators to increase grain production.

From the point of view of long-term trading, the technology of ironmaking must be handed over.

"It's so enviable."

The tribesmen sighed one after another, and the things they had accumulated in the past year or two of struggle were going to be exchanged for the ore that the Baiyan tribe had since they were born.

They are the protagonists of this world!

"Bai Yan takes the treasure but can't use it, we are so sincere, there is no problem with the transaction!"

Jun Qianqian grabbed the small wrench that Daze specially made for her, and clanked the iron.

Bearings are one of the most basic mechanical components, and the structure is also very simple, requiring only smooth steel balls and two layers of iron to assemble.

Daze is about to become a blacksmith like an external plug-in, and after only two days of exploration, he can make steel balls with smooth surfaces, but he still has to watch Jun Qianqian's demonstration of the work of assembling the inner and outer shafts.

"If you fix the wheels directly to the stick, then when you turn, the stick must also rotate together, so the car is unstable and the wear will be very serious."

If it is a normal horse-drawn carriage, it is enough to fix the wheels, but they are transporting ore, and the cart must be made very strong.

Otherwise, if the car breaks down halfway through, it will really be called a day and a bad place.

"The bearing is double-layered, and a lot of small steel balls are placed in the middle, and the inner layer does not rotate the outer layer, so that the wooden stick can be fixed at the bottom of the car, and only the wheels rotate!"

Jun Qianqian gestured, but unfortunately everyone was still at a loss.

"Forget it, you just need to know that it's a good thing."

Jun Qianqian let out a long sigh of frustration.

"I seem to know what's going on!"

Xiaoduo's eyes lit up, and he was the first person to understand.

"The children can be taught."

Jun Qianqian finally felt a little comforted, she looked at Xiao Duo, and showed a kind smile like a human trafficker.

Teenager, are you interested in learning mechanics?
