After entering the bird tribe, I want to farm

Bai Wu has been in contact with a lot of black gold during this time, and is very familiar with black gold.

The piece of black gold under his hand was lighter than the real black gold, it wasn't too obvious, but it couldn't hide Bai Wu's feeling.

Bai Wu turned her head to look at the light cloud.

Lianyun raised his chin slightly, if you look closely at his expression, you can see that his eyes are slightly narrowed and the muscles around his eyes are tense.

He's visibly nervous.

Bai Wu knew it clearly, Dan Yun absolutely knew that this thing was not black gold.

The tip of Bai Wu's tongue pressed against the palate, and a smile flashed in his eyes.

These wandering merchants are still too naive, and have never seen the strange deceptions of the later generations, so that they feel guilty when they do such a little bad thing.

Now let's see how they lower the price.

Seeing that Bai Wu and Nan Yao were silent, Dan Yun's smile froze on his face, and his voice became tense, "What's wrong?"

Bai Wu turned her head, "It's nothing."

Bai Wu continued to check the metal in his hand, it was heavy and cold.

This thing is not black gold, it is definitely metal, or metal ore.

Just don't know what metal it is.

Bai Wu handed it to Nan Yao.

Nan Yao paused as soon as he took over, he looked up at Bai Wu.He recognized the ore, it wasn't black gold.

Bai Wu shook his head imperceptibly, signaling him to keep quiet.

Nan Yao weighed it, then threw the ore back to Bai Wu.

Bai Wu put the ore back into the basket, folded his hands on his chest, and turned to the merchants, "What do you want to exchange for it?"

Bai Wu deliberately avoided the term "black gold" and only used it as a pronoun.

A traveling merchant behind Danyun rushed to say: "Red cloth. One piece of red cloth is exchanged for two pieces of black gold the size of a head."

Bai Wu glanced at the traveling merchant.

Traveling Merchant was a little guilty, but he looked back quickly.

Lianyun quietly protected his companion behind him, "This exchange is very fair. When we go to other places, we will exchange a piece of black gold the size of a head for a piece of cloth."

"Really?" Bai Wu smiled meaningfully at the merchants, making their scalps go numb.

Then Bai Wu said slowly: "Two yuan is too little, five 'black gold' for one piece of red cloth."

Bai Wu deliberately bit the accent on "Black Gold".

The traveling merchants had different expressions, and some of them had unnatural expressions on their faces, and they turned their heads to avoid Bai Wu's gaze.

Dan Yun: "Three pieces, no more. Three pieces of black gold the size of a head are enough to fill half a basket."

"You take a step back, we also take a step back, four yuan," Bai Wu said, "otherwise we will lose too much."

Dan Yun paused, gritted his teeth and said, "Three and a half yuan, we can't accept any more."

Bai Wu stared at him for a moment, "Okay, deal."

The swan merchants breathed a sigh of relief, greeted each other, and brought up all the black gold.

Bai Wu went to the warehouse and took out the red cloth from the house.

A group of people counted supplies on the top of the mountain.

Three and a half pieces of "black gold" the size of a head are exchanged for a piece of cloth.

The cloth of Bai Wu's family has been repaired, and each piece of cloth is about the same size, roughly enough for an adult orc to make a long robe with sleeves.

The "black gold" brought by the swan merchants is different. They are big and small, and they have various edges and corners, which are very difficult to measure.

Finally, Baiwu dragged a big wooden basin they used to make paper, filled it with water, and then put three and a half stones of suitable size into the water, and when the water overflowed, the water surface was just level with the edge of the basin. Take the metal out again.

Bai Wu said: "Put the stone in the water, the water surface is even with the edge of the basin, it's worth three and a half black gold, do you agree?"

Light Cloud nodded, "Yes."

The swan merchants didn't expect to use this method, they chirped and praised:

"This method is really good!"

"Wu, I understand why the birds and beastmen on your side call you a wise man, that's amazing!"

"This method is good, Patriarch, next time we do business with other people, we can also use this method!"

Bai Wu was in the center of the rainbow fart and remained motionless, only urging the swan family to continue.

In the end, the swan merchants exchanged 60 yuan of red cloth and 20 yuan of soap, and basically replaced Baiwu's inventory.

The swan merchants didn't stay with them too long, and flew away that day after changing the cloth.

They flew over the territory of the Bai people and didn't stop until the territory of the lion people. They had to rest in the territory of the lion people before continuing to set off.

In the evening, the sky is full of burning clouds.

Mosquitoes buzzed and flew, covering the sky like locusts in transit.

The swan merchants lit six bonfires, one in front of them and five behind them. The fires were covered with grass that smoked mosquitoes, and the thick black smoke scattered with the smell of grass.

"Patriarch, look at this cloth." A young man in the Swan clan took a red cloth and inspected it carefully under the firelight, "It still glows!"

The cinnabar red fabric is covered with a layer of warm orange by the firelight. At first glance, it seems that the light can flow on the fabric.

Light cloud looked down carefully, "There is no light, it is the firelight shining on it."

Having said that, Lianyun couldn't help but carefully touched the red cloth under his hand.

The fabric is soft and thick, the dyeing is even, and there is a faint fragrance, which makes people love it.

In the darkness, someone whispered, "Bai Wu has so many good things in his hands."

The chatterbox opened, and everyone praised the various good things that Bai Wu had exchanged for:

"When Bai Wu looked at Hei Jin, I thought he had discovered something, and I was taken aback."

"What's so scary? Even if the quality of the black gold we brought over is not that good, it's still black gold, and it's not adulterated."

"Anyway, I don't think it looks like Hei Jin, Patriarch, what do you think it is?"

After saying this, the traveling merchants of the Swan clan looked at Danyun in unison.

Dan Yun's long legs curled up, "I'll find Bai Wu next time, maybe I'll find out."

"Patriarch, let's exchange this batch of cloth and find Baiwu again? Exchange all those strange black gold!"

"That's right, patriarch, so much black gold, it's a pity not to exchange it."

"Patriarch, are you going? We still have as much black gold as a mountain, what if someone finds out and secretly takes it away?!"

"I think it's okay to go back later, fly a few more times, and we won't come out when it's cold in winter."

Everyone looked at their patriarch together.

Dan Yun nodded, "First change out the cloth that you bought today, and if you can get something good, you can make another trip."

"Oh——then I can definitely make another trip. Patriarch, let's exchange black gold for something delicious next time? Change it to bacon and mushroom sauce, and bring it back for the children to try."

"I want to change their knives. The knives of other tribes are not as good as their knives."

"Why don't you go back with some salted duck eggs? Their salted duck eggs are also delicious."

……

Bai Wu didn't know that the swan merchants had been discussing them for a long time.

He and Nan Yao were checking the newly acquired "black gold".

There is real black gold in this batch of black gold, but the amount is relatively small, and the rest are black unknown metals.

Bai Wu picked out the black gold, took the unknown metal and inspected it carefully, and felt that the feel and smell were very familiar.

Yes, smell.

Black gold smells of black gold, and this metal also smells of this metal, albeit faintly.

Bai Wu frowned and sniffed hard, but couldn't tell for a while.

He looked sideways at Nan Yao, "Have you ever smelled something similar?"

"No, this is the first time I have come into contact with this metal." Nan Yao put down the metal in his hand, sniffed his hand again, and frowned slightly, "The smell of this metal is heavier than black gold."

Bai Wu's sense of smell is worse, and he doesn't smell as much information as him. Hearing what he said, Bai Wu took a deep breath and sniffed hard.

"Hiss—cough cough cough, it smells so bad! This smell is so familiar!"

The metallic smell made Bai Wu a little nauseous, and he tilted his head in a retching posture.

Nan Yao patted him on the back and said, "It smells like blood."

Bloody smell!

Bai Wu was enlightened, "I said this smell is so familiar, it turned out to be rust! This metal is iron!"

"Iron?" Nan Yao pondered over this unfamiliar word with a strange pronunciation, "Have you seen it in your previous life?"

"I've seen it! Not only have I seen it, but I use it every day, but I don't use unprocessed iron very much."

The more Bai Wu looked at the ore in his hand, the more friendly he felt. He picked it with his nails and said, "The surface layer must be ferric oxide, otherwise it wouldn't be this color."

"Ferric oxide... what is it?"

"Iron oxidizes in the air, and it will produce ferric oxide." Bai Wu said cheerfully, "This is chemical knowledge, it is easy to rust and oxidize, and it is also easy to handle. Just wait for me to do a trick for you."

Bai Wu stood up and patted her buttocks, and dragged Nan Yao to find a small kiln by the river.

This pottery kiln has experienced wind and rain, and it is already half-old, with small cracks on it.

Bai Wu reached out and patted the thick kiln body, "When we have time, we have to make a bigger and stronger kiln."

Nan Yao: "I have reserved a place for you by the side of the room."

Bai Wu raised her eyebrows, gave him a thumbs up, and gave him a childish look.

Next to the pottery kiln, there is charcoal covered tightly with grass.

Bai Wu took some charcoal down, crushed the charcoal, ground it into powder, put it in a broken pottery pot, put crushed ore in it, put the whole pottery pot into the kiln, added charcoal and started firing the kiln.

Charcoal powder is an excellent reducing agent, which can reduce ferric oxide to iron. Is it iron in the kiln?You will know when they are refined.

Bai Wu and Nan Yao were guarding the kiln to light the fire, and they kept pulling the bellows, making the fire in the kiln extremely hot.

It was getting dark, and Anfei came down to ask them to have dinner, but they didn't go up to eat, but each ate two noodles and a piece of barbecue.

The orange fire came out of the kiln and reflected on their faces, flickering and flashing, and it burned until midnight.

Bai Wu and Nan Yao looked down from the kiln roof several times, and could see the fiery red metal in the charcoal fire, which even melted and flowed in the clay pot.

It wasn't until the middle of the night that Baiwu felt that it was almost burnt, so he used a stone stick as a holding tool, and carefully pulled out the clay pot.

The two looked at the clay pot in the firelight.

The clay pot cooled down quickly after being clamped out, and the objects inside gradually darkened from the fiery red state.

Afraid that he couldn't see clearly, Bai Wu took out a piece of firewood from the kiln and used it as a torch for lighting.

"Okay?" Bai Wu bent over and squinted slightly, and changed several positions to look left and right, wanting to see what happened to the metal inside.

Bai Wu took the stone stick from his hand, "You'll know when you get it out."

Nan Yao took out the relatively large black "stone" first, and Bai Wu saw the honeycomb-like thing on it, and blurted out, "It's slag!"

Nan Yao: "What?"

Bai Wu clenched his fists and shouted excitedly: "The slag that has been restored! Quick, look inside again, there should be burnt metal inside!"

As Bai Wu spoke, he stretched his hand forward, wishing he could snatch the blessing tool from Nan Yao's hand, and pour out the contents to see what happened.

Nan Yao held his wrist with one hand, "No rush."

Speaking of which, Nanyao took out the contents of the clay pot. It was a piece of irregular metal the size of a fist. It was light silver in color as a whole, and it still shone with fragments of light under the firelight.

Bai Wu's eyes widened, "Iron?!"

"I guessed right, it's really iron!"
