I'm doing shopping in the original

Bluebird and Little Cool have witnessed a great experiment.

None of them thought that the overheating could be so vigorous. The charcoal that should have been used as fuel and reducing agent was shaken into the newly improved stove. Add a hand drill to the wooden stick, you only need to reach out and press it up, and it becomes a semi-automatic blower.

"I really didn't expect that the principle of this hand drill can be used everywhere." Uro couldn't laugh or cry, although the blowers are also made of bark and wooden sticks, but their bottoms are made of stone instead of wood, so it is not easy to ignite, nor is it easy Being pierced, it will only turn back and forth. At this point, the reaction of the little cool brother is surprisingly fast.

The pottery that was used as a test object was re-glazed with a layer of plant ash, and it was not a big problem after being fired once and then fired. Originally, some porcelains were specially fired first and then glazed.

Their newly remodeled stove is not too big, and only one bowl can be placed. The bottom is tightly blocked by charcoal, and the bowl glazed with plant ash is placed in the middle, and then covered with a layer of charcoal.

"Would it be too wasteful?" Wuluo cherishes resources, and feels pain when looking at them. He doesn't know how many big trees have been cut down recently. In addition to the previous wildfires, he has to doubt whether to cut down like this. Here The lumber they have is enough for them to use for another three or four years at most. If the population increases, I am afraid that three or four years is still a delusion.

Yan Mu didn't squint, "Then can you control the dosage well?"

"Then burn it." Uro sighed, "I've lit the fire, please be careful to get out of the way."

After getting the charcoal, the fire burned more and more fiercely, far better than usual, and even came out of the furnace mouth to burn fiercely. The four of them got close together, sweating from the heat, and the color of the fire also changed, which could be seen directly from the naked eye. The orange color turned into an almost glaring white light, and Uro's eyes hurt when he saw it. He hurriedly looked away and asked, "I'm afraid the fire is too high."

Yan shook his head, and said with a serious expression, "It seems that there is no hope for stone-bodied porcelain. This kind of temperature is unbearable for ordinary soil, and it will probably be burnt."

"Is it still burning?"

"Burn, let's see how far the fire can go."

It's a pity that with such crude equipment and such rough tools, it is already the limit to turn the color of the fire into white light, and there is no room for the flame to rise further. According to Wu Luo and Yan's calculations, the temperature is probably above 1000 degrees. Bronze can be made by melting copper water and adding tin materials—but it is called bronze, but it should be called Jijin, which is more in line with this era. Bronze will turn blue-gray after it is buried in the ground. Its original forged color is golden yellow. of.

"This fire-fired copper is enough, but this furnace is estimated to need to be remodeled. Find a height so that the molten iron and copper can flow out, and we will put a mold below it for pouring, otherwise the high temperature may not be unbearable, or we just Can make one and destroy another."

Brother Xiaoku didn't quite understand. He thought that this kind of thing was similar to burning pottery, so he wondered, "What does it mean to make one and destroy the other? Can't you take it out after it's cold?"

Once the molten iron and copper are melted, it is equivalent to shaping. The container must be taken out of the fire and poured into the shape, otherwise all you can get is iron.

"I'll think about it again, no rush."

Wu Luo rubbed his brows, thought for a while and still couldn't get the answer, so he didn't think about it for the time being. Sure enough, he was a novice on the road, and he didn't know how to be afraid until he became a veteran driver. It's easy to want metallurgy, but thinking about it Words are inherently simple, but when you actually do it, you will encounter various difficulties.

Blue Bird asked weakly, "Wu, this kind of fire is too small."

The other three present all turned their heads to look at him, seeing that Blue Bird was covered in cold sweat, and tremblingly held up the isinglass that he had soaked in his hair, and stubbornly fought for the welfare of himself, "I boil the glue."

"Do you dare to use this kind of fire to boil glue?" Yan laughed, "I'm really not afraid of making a pot of mud."

In fact, Blue Bird is also very depressed about this point. He just thinks that the original fire is a little too small. He thinks that the cooking time is too long. The fire was about to burn out, and his eyes hurt when he saw it, and he felt scary. Putting people on such a fire would produce glue, not to mention fish maw.

"It's too big." Brother Xiaoku corrected him habitually, "Alan Bird, can you stop trying to play with the words you have learned, and just say that the fire is very big, and you must say that the fire is not small, you are very It’s easy to get it wrong.”

Not to be outdone, Bluebird responded, "If it's the tribe, there are too many, and I'm in a mess."

"If you don't understand it, you don't understand it, and the tribe talks a lot." Brother Xiaoku muttered twice, "I think it's easy to talk about."

Wu Luo fiddled with the iron ore for a while, but no one pushed the charcoal any more. The amount of charcoal was put down before, and at this time, the fire can be turned off to pick up some for later use. By the way, I will explain the principle of the blower and the use of the pottery kiln to Xiaoku. improvement of.Now that there is enough flame, it is not a problem to try porcelain. The melting point of ceramics is higher than that of bronze. As long as you try out porcelains that are more stable and can withstand explosions, you will have a crucible of copper water that you can use.

It’s just that the blower has another disadvantage. It doesn’t burn itself like a normal natural fire. It only needs people to add firewood or fuel regularly. It needs to start working without interruption, which means that there are two groups of workers. Work in shifts.

This kind of thing looks like it was born for Hua Helong.

It's just that the two of them are busy with the birth of the baby now, and there is really no way to do this. In the final analysis, there are still too few people. Since there are too few people, it is better to help cheat.

Once the molten iron can be smelted, Uro has a reasonable reason to take out the corresponding tools. He doesn't mind using the golden finger. The problem is how to use the golden finger so that people don't feel like it's just a pie in the sky.

Just like cotton quilts, cotton and linen have already appeared on the stage, but they are not as good as they are made, and they can be modified if they are not so detailed. At least everyone already knows the principle.

It was just a fire, and it took everyone an entire afternoon. They finally waited until the fire was extinguished and the furnace cooled down naturally. The pottery bowl was taken out, but the result was beyond everyone's expectations.

The mouth and bottom of this pottery bowl were completely melted, in short, it was burnt, stained with charcoal ashes, but the cup wall has been vitrified, and even formed a gray glaze.

"It's made into porcelain..." Yan Du couldn't believe it. He tore apart the porcelain in a daze, and inspected the complete fracture of the cup wall. The carcass had been sintered. Although it was not complete, it was indeed porcelain.

The section of pottery is rough and there are many particles, which is not as complete as porcelain.

The two may seem indistinguishable, but they are actually very different, especially in this day and age.

"It seems to be mixed soil. After pounding the mud before, they began to sift the soil. They didn't deliberately distinguish the soil quality. Sometimes they even mixed the scattered powder together to knead new pottery, so the clay part was not resistant to high temperature and was fired. , but the porcelain clay has turned into porcelain, or porcelain block." Wu Luo thought.

Yan couldn't help but look at Wu Luo, and said with emotion, "You really live in a land of good geomantic omen."

Wu Luo couldn't help but rolled his eyes, "It's easy to say, being stared at by wolves and beasts, being chased away by wildfires, is indeed a treasured place of geomantic omen."

Now that the fire has been confirmed, all that remains is to wait for the new materials and the blast furnace, which cannot be completed in a day. It is not considered an invention of primitive people, so is Yan a person of this era?

Uro is not sure, in short, change it first.

After having Yan, the kindergarten courses can be skipped to the high school remedial classes immediately, and Uro doesn't need to rack his brains and painstakingly tell Amber what the principle is, why they do it, and how to find out what they have neglected.These things do not require Uro to recall and sum up experience by himself. Yan has enough experience, and he is very familiar with this world, so he can reconcile the conflicts between Uro and this world.

"Is there anything else I can do for you next?"

Yan slowly said, the men in the tribe don't get sick very often, most of them are as strong as cattle, or they were injured, but they were injured just before, and now they are still free, and there are no patients worth taking care of.

He has been slacking off for almost the whole summer, and he is somewhat embarrassed. After all, joining the tribe requires some sincerity, and he lives in such a loose manner. If it weren't for his medical skills, he would have been kicked out long ago. Bright moonlight, live comfortably.

He is not a person who belittles himself, nor is he a person who does not know what to give back. No matter how small the tribe is, it is his own choice to join. The Sun Moon tribe has indeed given the best things that can be given.

"Oh? Being so active actually scares me a little bit." Uro said with emotion, "I have nothing else to do next. Amber wants to open the house, and the tree wall can't be built for the time being. Now I think it's best to treat the wolves Beasts will be extinct, what do you think?"

Yan Xinran agreed, "Very good."

It's very good, but it's a pity that the plan couldn't keep up with the changes. Before Uro said it was time to kill the wolf beast, Amber had already done it ahead of time.

And the neglected blue bird and little cool brother stood alone by the fire, and before they had time to excitedly admire the newly fired porcelain blocks, they watched Wu Luo and Yan showing surprise and joy, and then the two figures happily Go away - even Uro didn't even give an explanation afterwards, only the two of them looked at each other, not knowing what happened this afternoon.

Brother Cool squatted down and looked at the fan and the nozzle.

Bluebird kicked his thigh and asked "what's wrong with you?"

"I'm thinking—" Brother Xiaoku thought about what happened to Hei Tao before. It's not been a long time, but it seems to be very far away. Every time Wu can come up with new things, their progress is so fast. It was frightening, and he didn't feel anything in it, but recalling everything that happened in the tribe this year, he began to be in a trance, "Am I dreaming?"

"Snapped--"

Brother Xiaoku felt a burning pain on his face, so he screamed on the spot. He immediately came back to his senses and looked at the blue bird with a caring expression in front of him, "Xiaoku, don't sleep, I will eat you later."

Little Cool Brother "..."

Patience, patience is one of the best qualities of human beings.

Brother Xiaoku's face twitched slightly, he covered his red cheeks, and suddenly felt an impulse from the bottom of his heart to grab the clay and bury the blue bird, and said angrily, "I was thinking, how to put this fire in the kiln?" Go inside. It was like this in the past, Wu told us to think for ourselves and to look at what happened in detail. Although he knows everything, we can’t keep asking him.”

"Why can't we ask?" Blue Bird asked curiously, "Since Wu knows, why can't we listen to him?"

Brother Xiaoku thought for a while, then he shook his head and said, "I don't know, but Wu said that we can think of things he doesn't know, so we can't keep asking. If we ask too much, we won't think for ourselves. Do you understand?" ?”

Bluebird pretended to think for a moment, "Hmm... I don't understand. But now that we have such a big fire, it's very convenient to do whatever we want, ah - it's strange, why didn't we think of this thing, but the witch just took it all at once. Come out, has he burned?"

"Anyway, the witch has always understood." Brother Xiaoku pointed to his eyes, "No matter what it is, even if he didn't tell us, he will know it at a glance."

The blue bird also had lingering fears about this matter, "Yes, I know, we picked up beautiful stones before and wanted to take them back to dye Xisi's clothes, but the witch said that they have names, who would name the stones on the ground? Ah, there are so many beautiful names, how strange, is there anything a shaman doesn’t know? The one named Yan is also a shaman.”

Brother Xiaoku just held his heart and said, "I want to be called Peacock too! It sounds nice."

"It's getting dark, let's go." Blue Bird originally wanted to chat with Brother Cool for a while, but when he looked up and saw the sun tilting, a red heart immediately jumped up, "A Jie is coming!"

Ajie Ajie.

Little Ku, a single dog, is obsessed with fire and cannot extricate himself. He just wants to be a great magician and has no interest in human love.

But it was indeed dark, and it was going to be dangerous. They had to go back to the cave—the wooden walls were demolished recently, and everyone seemed to lose a little sense of security, and they became very unaccustomed.

The hunting team and gathering team had just returned at this time.

One after another, there were 23 wolves in total, three cubs, and all the others were adult wolves.

The wolf king's fangs were almost broken off, and his mouth was bloody. He had been dead for a long time, and was brought back by Hu Po on his shoulders. The wound was pressed on his hair, and the stinky blood flowed down her cheeks. She walked over without paying attention. , looks like a giant monster when the lights are not on.

"Am I wrong?"

Uro looked at the corpse of the wolf beast in the open space, subconsciously moved his hands and asked the people around him.

"You may be so short-sighted that you can't see clearly, but my eyes will definitely not be a problem. It's true, the wolf beast extermination plan you planned is useless. If I knew it, I would help you burn it with that bellows."

Yan answered him.

"Don't mention that piece of paper, I will want to hit you."

Yan shut up wisely, and didn't say the sentence that really deserved a beating.

You can't beat me.

"Witch?" Amber wiped the blood in front of her eyes, some of which had dried up on her cheeks, and it hurt a little when she rubbed it. She suffered a lot of injuries, and she twitched a little when she moved. Fortunately, the bruises on her stomach It has been completely dispersed, so that it will not affect the action. She looked at Wu Luo, who was inexplicable, and asked, "What's wrong with you?"

Wu Luo was silent for a moment and said, "You said you were going to hunt animals today, but did you mean to kill wolves?"

"Yes." Amber nodded and said, "I asked Mo and the others to see them before. They have been hungry for a long time. Hungry wolves are scary and fragile. They will be disobedient at this time. I took the men to dig the trap, Tempt them with meat, and then wait for them to scatter, if the wolves can't beat us, they will all die."

The wolves are united, but that is under the guidance of the wolf king. Their individual strength is not enough to be feared, so they have to huddle together to keep warm. However, the wildfire has caused a change in the hunting range. They are hungry. There will inevitably be conflicts, the positions of the new and old wolf kings will change, and after they have been targeted, they have repeatedly fought and failed, and they have not suffered enough, so they will definitely attack again.

And they locked their targets on humans, and humans also locked their targets on them. Amber seized the most appropriate time to attack.

The scariest thing about a pack of wolves is that they are commanded by a wolf king, but the starving beasts don't know what it means to be obedient.

Winning this battle was not easy, even a bit reckless, but it was not tragic.

"Fortunately, there are lacquered birds."

Amber pressed her shoulder, and she said, "It flew up and ate the eyes of the wolf king. It would be even better if it didn't just like dryness."

Qi Ku, who was stuck by the fat bird and couldn't even find a partner, was accepting the congratulations from the men with a sad face. Although he was panting after running for a few steps, he had improved a lot when the Sun and Moon Tribe was full of meat, and he was a very good person. He is a master of traps, and he also raised Fat Bird, the air force, so Amber took him out.

He has also established great achievements, or his fat bird has made great achievements.

The attack by the wolves was not completely fruitless. The corpses that were hung outside were dragged away and eaten by them. The sick woman was burned, but the reason why there were only four left was not all because of illness. Some were dragged away and eaten alive. Their physical strength is much worse than that of the tribe, and they rarely react when they are attacked by wolves——

No wonder Amber was not in a hurry to build the wall, and even demolished the wooden house and the tree wall to prepare. It turned out that she already had plans to exterminate the wolf den. Apart from burning trees and waiting for creation, she probably went to dig traps.

"Very well done." Wu Luo said slowly, his eyes swept over everyone, and he explained his doubts slowly, "Everyone is injured, after dinner, please ask Yan to help take a look."

Amber nodded and said, "I know, eat later and peel the skin first."

She took out a row of bloody spikes from her animal hide, groped for a while, seemed a little hesitant, and finally said slowly, "Witch, how about using spikes for the new reward?"

"Huh?" Uro said in surprise, "Yes."

Amber was silent for a moment, her hands were covered with blood and wet, and she was a bit overwhelmed for a while. Usually, the winning prizes are food and the like, but if the food is given for a long time, some people always eat more and some eat less. After the food can be stored, the rewarded person can have their own private food.

This situation is not very good. Amber can't say what is wrong, but she just thinks it will easily cause disputes, but Uro has no intention of proposing. She can only think about how to plan and how to deal with it.

Everyone was not seriously injured. The hungry wolves were indeed ferocious, but it depended on how hungry they were. Primitive people have been with this world for a long time, and they don't have the condescending thought of people in later generations, let alone think that they are superior to animals. In addition, just as wolves will come to detect the time of human activities and try to kill young children and adults with disabilities, humans will also understand the habits of wolves.

Just like Amber, she can see that the wolves are replacing the old and new wolf kings, she knows that the wolves are in chaos due to hunger, and she knows that the new wolf king has just ascended the throne and cannot fully command the wolves.

After the people left, Yan Cai asked with great interest, "Is this also the case in your plan? Go straight ahead."

"If it were me, I would ask everyone to collect herbs related to anesthesia, the kind they often use to apply wounds, and then boil it into a potion and apply it on food, or fish, or dead animals." Uro slowly He said, "Hang it outside to dry or put it on the ground. Wolf beasts are very used to us handling food, so they will definitely steal it, or be bold and let you send it to the wolf's mouth."

Yan Ruo thought thoughtfully, "Your method is more suitable, but it's a pity that you brought it up too late."

"Is it late?" Wu Luo said quietly, "I think, if I live with Amber under this blue sky, her chances of surviving are far greater than mine. She doesn't know a safer way, but she is very Good at observation, wolves replaced the wolf king, hungry, and I would have thought that the hungry wolves would be more ferocious, but she seized the opportunity to wipe out the grass."

"All creatures are struggling with each other on the food chain, and humans have not yet reached the top."

Uro chuckled, "The safest way may not be the most suitable way to survive, nor may it be the best education. Not every time there is such an opportunity and preparation, Amber chooses her plan, only people get hurt. , no one died, and that's not bad."

"What if someone dies?" Yan asked him, "Will you still see so many advantages?"

"If I use my method, I will definitely succeed. It's too arrogant to think so." Uro shook his head and said, "You have too much confidence in me. Anesthetizing the wolves is easy to say, but in fact it requires us to pay. A lot of food, and enough narcotic herbs. At this time, wolves can't find food, and we can't find it either. It's just supplemented by fish. It's a palliative measure at best. Determine whether we will be paralyzed by eating the meat of wolf beasts, and make preparations for these meats."

Only then did Yan really smile, "You are very calm, much calmer than I thought."

"Thank you, if you don't dig holes in your words every time, my thanks will be more sincere."
