The spectacle and miracle in front of him once again shook the hearts of the clansmen. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info Patriarch is just too powerful. Everyone was whispering.

And Yao Huo ran to Yao Ran's side. Yao Ran walked close to the front two people together, and slowly lowered it down at the same time, the hanging log, when it is easy to go up the mountain and difficult to hang up, the weight is on the winding rope, and the painting that is put down needs to be held by the hand holding the wooden rudder to be held steadily, otherwise it will fall rapidly, and it is very likely that the log will roll and hit the crane that has just been built.

The two slowly put down the log, and the eyes of everyone present converged on the two of them. The patriarch is really powerful, such a big piece of wood can be pulled up by one person. Two people can put it down.

After the log landed, the two of them breathed a long sigh of relief together, and then looked at each other and smiled. Yao Ran patted Yao Huo's shoulder and said, "Good job, but next time remember, make two rudder wheels, one on the left and one on the left, so that you don't have to worry about problems, and you can use multiple people to operate at the same time." Once the crane is built, we're going to make another big guy. I'll leave this equipment here to build a house first. A knowing smile hung on Yao Ran's face.

This is the first large-scale composite tool since the last grinder. Now I'm stable. It is a good time to improve people's livelihood, develop technology, and popularize knowledge and education. With the discovery of iron ore, it is believed that it will not be long before a variety of tools and more complex machinery and equipment will continue to appear. Wooden wheels with iron axes, fixed with iron nails and hoops, wooden carriages, no, there are no horses yet, only Kodomon. Kodomon isn't bad either. If there is enough iron ore, you can also make iron mills, which can be used to level roads.

Thinking of this, Yao Ran suddenly remembered that he had to check the situation of charcoal today. Yao Ran patted Yao Huo's shoulder and said, "Arrange a few smart and honest people who are familiar with the operation of the crane and safety precautions." After that, we started to prepare for the waterwheel, and we still have a lot to do. ”

Yao Huo nodded excitedly after listening to Yao Ran's words, and after nodding a few people, he began to explain loudly to several people how to use this equipment and precautions when lifting.

Yao Ran walked towards Xiaoping with Xiao Ash, and shouted before he got to his side: "Stinky boy, didn't I let you look at the charcoal pit?" Running to see the excitement is coming, hurry up and follow me to see how the charcoal is doing. Xiaoping is also familiar with Yao Ran, and he doesn't explain Hehe's smirk.

Xiaoping is not a fool, knowing that his teacher is happy now, he has no intention of being angry. Hurriedly followed Yao Ran's pace, and Xiaoping was also very curious about the wood that was covered in the pit and lit the fire. If you cover the wood and burn it, you can get the charcoal that can burn at a higher temperature and is more likely to catch fire?

The charcoal pit was not far away, but more people were attracted by the magic of the crane over there, and Yao Ran only had Xiaoping, Hua Tuo, and four sedan chairmen to follow. Of course, there is also the little gray gray in the back.

When he arrived near the charcoal pit, Yao Ran checked it with the retinal system, and found that the dozen or so charcoal pits burned on the first day had only residual temperature, and there was no dark fire burning, indicating that the charcoal was either burned successfully, or burned and turned to ashes.

In fact, the principle is very simple, if the charcoal pit burns well and there is no air leakage, the charcoal in the pit will leave charcoal after it runs out of oxygen. If there is a leak, it will keep burning, and there will be a dark fire, and finally it will be a huge air pressure difference at the moment of opening the pit, and the surrounding people and air will be sucked into the hole, and then a huge flame will be spewed, and if it burns out, it will naturally be left with a pile of ashes.

There is no problem with the dozen or so charcoal holes in front of me. Yao Ran put a rope on the clay cover at the mouth of the charcoal hole, and then directly pulled up the lid, in this process it had to be pulled by several men together, because the air pressure inside and outside the cave is different, because the oxygen in the cave burns out when burning, and there is no air pressure change outside the cave, so the pressure difference between the inside and outside causes huge pressure, so it is difficult to pull the lid open.

Everyone shouted the trumpet together, pulled three or four times, and finally "Bang!" After the sound of air explosion, a burst of black smoke floated gently for a few seconds, and when the black smoke settled, Yao Ran pointed to the second charcoal pit and said, "Go and pull that one away!" ”

Although he commanded everyone to open another charcoal pit, Yao Ran himself walked towards the first charcoal pit that had just been opened. Walking closer, in the charcoal pit nearly three meters deep, there were sections of black charcoal, although they were not as neat as when they were placed in the first place, but there was no chaos there.

Yao Ran clenched his fist in his right hand, slashed hard across his chest, and muttered in his mouth: "Oh~yes~ I can finally eat charcoal kebabs." The two apprentices beside him looked at their teacher in surprise.

"Isn't this for ironmaking?" Xiaoping pointed to the black blocks in the pit.

Yao Ran instantly became a red fat man, his face was flushed, and then he pretended to be calm and solemn and said, "Well, these charcoals are indeed used to make iron, but what...... But what...... Oh yes, yes, but because you need to test the calorific value of some of these charcoals, ahaha. Of course, meat is used to test the calorific value, so you need to grill some meat or something to see if the fire is strong. Do you understand? Yao Ran admired his imagination. I think the story I made up was seamless.

But the expressions of the two apprentices clearly showed that they didn't believe it, Yao Ran said one by one, "Hahahahahaha~" After laughing dryly for a while, Yao Ran turned around and said to the two apprentices: "The temperature inside is not high, you two go down and bring the charcoal up, we are good for barbecue, ahhh~ We are good at ironmaking." ”

Hearing Yao Ran's words, Hua Tuo and Xiaoping's faces were as black as charcoal, isn't this malicious retaliation? The two glanced at each other, then tied the rope with a bitter face, and with the help of the people around them, they went down to the charcoal mine.

Yao Ran saw that the two apprentices had entered the pit, and he was not as embarrassed as he was just now. After thinking about it, Yao Ran turned his head and left.

Xiaoping and Hua Tuo, just filled with two small baskets of charcoal is already black, charcoal and coal are different, just fired charcoal is lightweight, but the fly ash is also large, the bottom charcoal even has a little hot residual temperature.

"It's all your fault, how can you not trust the teacher!" Hua Tuo suffered with a black face that couldn't see his facial features, "My dignified physician (Yao Ran's professional name), but he is here with you to treat diseases, woo, woo, woo, woo~"

"I didn't speak just now!" Xiaoping said aggrievedly.

"Didn't you speak?" Hua Tuo asked in surprise.

"You see that you didn't believe it in the first place, neither of us spoke, but let the teacher see it! I didn't wronged you when I was punished by the teacher for working. ”

At this time, Yao Ran's voice came from the top of the pit, "I didn't punish you for your work, there is no distinction between high and low for working for the family." How did you move the charcoal and wronged you, Mr. Doctor? ”

Hua Tuo's small eyes shook on his face full of black ash, and he quickly explained: "No, no, no, no.... There is ~" The last long note is about to be pulled into a song.

Xiao Ping grinned dryly, and a row of small white teeth with a brush was revealed in the pitch-black pit. I just can't see my face.

Yao Ran's voice did not come down again, but Hua Tuo and Xiaoping put down a rope sleeve above their heads.

Xiaoping raised his head and looked at the rope carefully, and made a pergola with both hands to avoid the harsh sunlight, which turned out to be a crane. The teacher was so thoughtful that he pulled the crane over to carry the charcoal. Immediately after that, several mines were thrown down.

Then I heard someone shouting, "Fill these baskets, and pull you both up, and the teacher said, 'You are the first to make a mechanical lift.'" ’

Hearing a new term, Xiaoping's eyes lit up, what is the elevator? But Hua Tuo didn't react when he heard it, because Yao Ran deliberately asked Hua Tuo to treat the sick and save people, and to keep his personal hygiene and tidiness when seeking medical treatment, so Hua Tuo often wore a dehaired animal skin, short leather pants that fitted, and wore wolf skin boots similar to Yao Ran's leather boots. Inside the pads of straw mats and leather shoe insoles.

Now it's okay, this fashionable dress is all in this pit, and even the complexion is dark. Hua Tuo was passive and slacking off because of his dirty clothes, but Xiaoping was really active and not afraid of being dirty and tired, Yao Ran saw the performance of both of them, and didn't say anything but had a smile on his face.

With the efforts of two people, all the charcoal was loaded into the basket. There were still two big baskets left, and Hua Tuo sat on them, letting Xiaoping tie the rope on the side. Wait until everything is tied up and checked. Yao Ran spoke: "Leave 4 pieces of charcoal to form a tic-tac-toe shape." ”

Xiaoping did so. Hua Tuo didn't dare to sit lazily, and was about to struggle to stand up, but saw that Xiaoping had already done it in the basket, and then Hua Tuo reacted and quickly sat down in the basket, holding the rope tightly in his hand, looking very nervous.

Before the two people in the pit could speak, Yao Ran said to Yao Huo: "Let's start!" Although Yao Huo didn't know why the two junior disciples were working in the charcoal pit, he knew that it must have something to do with the teacher, and it didn't seem like a good thing, so now he obeyed his words and forbade it.

Standing on the crane site, the wooden steering wheel that rotated easily, and the lifting rope on the crane pulley were gradually pulled up. Two bright black eyes appeared inside the basket full of charcoal. Seeing Yao Ran standing not far away, he also showed two little white teeth in the dark.

made Yao Huo almost miss and threw them back again. Hook the entire hook with a bamboo pole. The crane kept putting ropes, and the whole basket was pulled to the ground, and the two people got down from the basket, Xiaoping danced excitedly, and he was hoisted to the ground without doing anything. The immersive experience made Xiaoping more and more interested in complex transmission equipment.

Hua Tuo is different, he is not interested in these ropes, pulley transmissions or anything, not to mention soiling his clothes, so Hua Tuo's little mood can be said to be a little sluggish.

Yao Ran waved his hand and said, "The three of you will come with me, and the others will dig up all the charcoal and send it to the pergola." ”

Yao Ran turned around and walked onto his sedan chair, turned around and smiled evilly at the two little black men and said, "Let's go, I'll take you to wash it." ”
