"Damn, livestock!" Fengyun shouted angrily out of the hut and in the direction of the valley road.

That guy actually took the copper axe and copper knife away!

The copper axe is good to say, he still has a spare, but the copper knife is just that! He is used as a kitchen knife and a saber, and now he is gone, and he has no matter how to cut meat!

Pointing at the heavens and cursing the earth, Li was greedy for a while, Fengyun could only go back in frustration and chop some pieces of meat with difficulty with an axe and throw them into the pot to cook.

"Brother!" Gray Liu'er rubbed his eyes and sat up.

"Here!" Fengyun sat in the wooden house, pinching a pile of wood chips, and the ground was full of them.

"What is this?" asked Gray Liu'er curiously.

Fengyun said: "Map." ”

"Oh. Gray Liu'er was not interested in this, and ran to the stove to lift the lid of the pot.

"Don't do it, scoop it with a spoon!" Fengyun exhorted, looking down at the map on the ground.

Wang Yue painted very carefully, but due to the limitations of materials and technical means, the final product was not exquisite, but he could already understand the surrounding situation.

"Copper mines, where are the copper mines?" Fengyun searched up and down. Without the copper knife, he couldn't do a lot of things, and he had to find a way to refine it again. Since Wang Yue can smelt copper, then there must be copper mines nearby, and after looking for a long time, he finally saw a line of markings at the bottom of the map: Oak-shaped mountains, with blue and green copper ores.

Fengyun measured it with his fingers, and according to the size of Wang Yue's map, it was almost three hundred kilometers, and there was a mountain range called Mao Mountain in the middle.

"Do you have to run so far to pick up a copper ore?" Fengyun muttered, and then he realized how precious those copper ores in the workshop were, and they were carried back by Comrade Wang Yue after running 600 kilometers!

It's a bit far! Fengyun hesitated a little, this place is not like the later generations, where do you want to go to a train or plane, that's 300 kilometers, 600 miles! Just rely on your legs to walk over, at least 10 days! How can it take a month to go back and forth, is it cost-effective? After thinking about it for a while, Fengyun decided to go to the workshop first and then take a look at those few pieces of copper ore.

"Obtain Azurite Ore*1. ”

"Obtain Chalcopyrite*1. ”

"Obtain Malachite*1. ”

......

After searching all the workshops, Fengyun only found three pieces of copper ore, and the types were different. Playing with brightly colored stones, he realized that he didn't know how to smelt copper.

A fire was lit in the courtyard, and Fengyun was a little hesitant to throw the ore into it, he wasn't sure if he could burn the copper directly by putting it on fire.

Before activating the skills, he was purely blind to the cross-industry technology, and the system activation skills were not regular, these days he went to the wheat field every day to pull weeds, remove insects, and urinate all contributed to the field as fertilizer, but still did not activate any farming skills.

And copper smelting is much more difficult than farming, Fengyun is not sure if he can activate a skill after burning these ores, after all, he only has these on hand, and he will be gone when he runs out.

Of course, you still have to burn it, but you have to plan it well.

Fengyun returned to the back room, took out the carpentry box, took out the small one-handed bronze hammer from it, and came out to smash as much ore as possible.

First threw the azurite ore into the fire and burned it for a while, Fengyun pulled it out with a branch and looked at it, but found that it was only burned black, but the system did not prompt it at all, which was very helpless.

With black charcoal marks on his hands, Fengyun scratched his scalp and muttered: "Is this copper smelting a physical reaction or a chemical reaction? This ore is not pure copper in it, right?" For the first time, he regretted that he didn't study hard when he was in school, and he was so passive now.

But it's useless to regret it now, he can only rely on himself to slowly grope for it.

Engaging in scientific research is a time-consuming, laborious, and low-yield work, and I haven't made a name for myself after a busy morning.

For the sake of his stomach, he still had to go out hunting, try to hunt as much prey as possible, and make time for the next two days to study how to smelt copper.

Hunting depends on the weather, and whether there is a harvest or not, in addition to experience, luck also accounts for a large proportion. However, Fengyun has Gray Liu'er and Mandrill as companions, which can expand a lot of search area, so it is also full of harvest when you come back before dark.

There was no trace of Li Yan outside the valley, so I thought he had gone away.

Taking advantage of the sun's down, Fengyun carried a bucket to the spring to receive water and poured some water on the wheat seedlings who had just emerged in the wheat field.

The firewood in the valley is almost running out, Fengyun simply did not make a fire at night, in this time and space, not to mention anything else, the night sky is really beautiful, even if there is no fire, the night will not be too dark at all, but can appreciate the beautiful starry sky more clearly.

There is a lot of demand for firewood used to boil water and smelt copper, and it just so happened that Fengyun had been trying to make a new bed, so he simply spent a whole day cutting down dozens of trees the thickness of a basin outside, cutting them into wood with planers, and throwing them in the sun. Of course, there are bigger and better materials, but for now he can only resist such thick and thin wood.

For the next two days, Fengyun spent all his energy researching how to smelt copper. After burning it a few times, he found that the flame from the fire was not hot enough to burn the ore without reacting. So he set up a stove and tried to put the ore in it to be calcined, but the firewood took up too much space and the fire was still not concentrated. He began to figure out how to make charcoal again, but the charcoal needed to be re-coiled into a larger, sealable stove......

Only then did Fengyun realize how important the traverser inheritance was, without these things left by Wang Yue, it was definitely not something that could be done in a year and a half to refine such a set of tools from scratch.

Every time Fengyun burns ore by the fire these days, Xiaobai is watching quietly from the sidelines, and Fengyun doesn't care, anyway, he hasn't figured out the way yet, so he just looks at it.

However, after several failures, Fengyun finally figured out something.

It took the morning to build a clay stove and burn it with firewood to dry the walls. Fengyun re-chopped the firewood into small pieces and piled them up in the stove. When the fire was raging, he threw the little remaining copper ore into it, and then fanned the wind desperately with a piece of the skin.

Half an hour later, the flames were extinguished, and Fengyun picked up the embers, picked out a blackened stone, blew it, and placed it in the palm of his hand.

"Obtain slag full of impurities*1. ”

"Damn! wasted again!" Fengyun threw the slag aside in frustration and sat on the ground panting.

Little White walked over and kicked the slag on the ground with his front hooves, as if he was interested.

"What, do you want to learn, I'll teach you?" Fengyun said with a smile.

Xiao Bai glanced at him and asked, "Are the tools you said were made of these stones that can carry people to the moon?"

Fengyun shook his head and said, "It's with the metal inside." ”

"Metal ......" A strange look flashed in Xiao Bai's eyes, paused, and said with a smile: "If you have the opportunity, you must see the world you said with your own eyes." ”

Fengyun looked up at it, didn't speak, got up and pulled out the ashes from the stove.

Xiaobai smacked his lips and went to the side again.

Fengyun cleaned the hearth, re-laid the firewood, and used the structure of the firewood itself to create a space for air circulation. After laying it, he threw the last two pieces of turquoise into it, thought about it, took out another one, and lit a fire.

"Obtain slag full of impurities*1. ”

As expected, it still didn't work out.

"!" Fengyun scolded angrily and kicked against the furnace wall. The hard-burning stove was not kicked, but shook the soles of Fengyun's feet.

Look left and right, there is no one, Fengyun squatted down and grinned and rubbed his feet, full of irritability.

"Grandma's! Can't Lao Tzu not refine? If it's a big deal, use a copper axe to chop meat!" Fengyun scolded and said, wanting to catch Li Greedy and beat him up in order to dispel the hatred in his heart.

After working for a few days, but not getting a fart out, he returned to the house in a rage, threw the last piece of turquoise into the stove, and lay down on the haystack to sleep.

In the past two days, Fengyun also sent Gray Liu'er and Xiaowei out to hunt, and he himself concentrated on refining copper at home. But until today, he has consumed all the ore, and he has not smelted half a piece of copper, which makes him very depressed.

How did Wang Yue come up with it? Why can't I? Fengyun is half dead and can't figure it out. Could it be that it was through the copper smelting method left by his predecessors? But why didn't Wang Yue leave it to me? Lying on the grass and tossing and turning and unable to sleep, his mind was full of such questions.

Sighing, Fengyun sat up, walked to the stove, scooped up a spoonful of hot water from the pot with a wooden spoon, and drank it as he blew.

The fire on the stove has not been extinguished during this time, in order to save trouble, Fengyun will add a thick big wood to it every time he finishes cooking, let it burn slowly, and maintain the fire.

The clay pot is constantly burned by fire, so the pot is often filled with half a pot of water to prevent the pot from drying out.

After drinking a spoonful of hot water and sweating, Fengyun sat in the shade at the door blowing the wind, and his mood slowly calmed down.

Fengyun suddenly laughed and shook his head self-deprecatingly. It is said that it is easy to go from thrift to luxury, and it is difficult to go from luxury to thrift, and this is indeed the case. When he didn't find this, he didn't kill fish and eat meat with wood chips, and he didn't starve to death? With a copper knife, it is naturally convenient, but without a copper knife, there are other tools? How can he be stumped by a knife? Thinking of this, Fengyun's mood is much more comfortable, and sometimes, he still has to explain himself!

Standing up again, Fengyun's face had a smile on his face, and he was even in the mood to whistle.

He figured it out, what Wang Yue had accumulated after living here for a hundred and eighty years, and he wanted to get it out in a few days, but it was too simple to think.

Can't be in a hurry, if you're in a hurry, he's in a hurry, anyway, he has time.

After the mood calmed down, Fengyun's mind came alive again, the wood outside the valley should have been dried, and there was no need to smelt copper in the afternoon, so he simply got it all back, and he would take a bed in the next two days.

The long sawn wood left by Wang Yue should be camphor, which has not been eaten by insects for all these years, and is still very strong, but the saw blade is a little rusty, and after Fengyun took out the grinding stone to polish and polish, the saw blade returned to some of its former colors.
