Two days later, Lu Jingzhi ordered his undead infantry to call the village chief, and ordered him not to bring it this time. Sure enough, this time the undead infantry politely called the village chief over, and even let the village chief walk in front. Lu Jingzhi was very puzzled, when did this undead become so civilized? It was only when he got closer that he realized that they didn't know what civilization was at all, and the village chief was kicked by the undead infantry all the way to trot, but the village chief's trotting was not as fast as the undead infantry's walking speed.

"My lord, your kindness......" When the village chief saw Lu Jingzhi, he thought of the mask used in the past two days, although it was troublesome to change it every two hours, but it was much better than coming back every two hours.

"Excuse me. Lu Jingzhi couldn't accept the appearance of the young village chief singing praises at every turn, and bluntly rejected him to say this, saying: "I've been here for two or three days, this day is not long, it is not short, how are the village chief's taxes prepared now?"

The village chief shouted "Come on!" at the outside of the house, and immediately a group of people carried several baskets of ore and sent them over, and piled them up not far from the door of the house. The village chief smiled and said, "My lord, you see, our village's tax has already been prepared, and you can take it whenever you want." ”

Lu Jingzhi looked outside the house, okay, this is exactly the same as the tax prepared by the village chief when he first came to this village. Immediately frowned, and said, "Doesn't the village chief think I'm very young?"

Although the young village chief didn't understand what he meant by asking, fortunately, he could hear that the words were not good, and said uneasily: "My lord, do you think we pay less tax?"

Lu Jingzhi's nostrils snorted to the sky, and when he saw the young village chief trembling, he said: "If it weren't for the village chief's eldest brother bullying me for being young and ignorant, I wouldn't have coaxed me with that tattered belongings a few days ago." Not to mention that you burned charcoal to make masks to increase production, but without that mask, you wouldn't have taken back any of the freshly picked in the past two days. ”

When the young village chief saw that Lu Jingzhi had broken his words, his heart also settled down, and he replied to Lu Jingzhi: "My lord, it's not a small one who dares to deceive adults, but I was given by adults, with this mask, mining has lasted five days a day." In the past two days, he also made up some sulfur, which should have been brought back to the adults to pay the errand, but it was just ......" He glanced at Lu Jingzhi, and there was no uncertainty when he met, so he continued: "It's just that in a few days, the 'over there' will also come to collect taxes, and if they can't pay it, they will force our people to deduct the taxes." If we take away a few more strong laborers, we are afraid that our village will be destroyed. ”

Lu Jingzhi also knew that what he said was the truth, but everyone has such a mentality, the current level cannot be outdated, and the net worth must be passed; if the current level can be passed, the net worth must be exhausted and the strength must be accumulated to pass the next level. Of course, Lu Jingzhi didn't want to let such a village be ruined like this, it's a big deal to wait for more in the future, and then come over and collect more.

Lu Jingzhi's face sank, and he feigned anger and said: "The eldest brother of the village chief is so calculating to me, it seems that the young master is really a child and is easy to coax." Shouldn't you have made it clear to me even if you have a thousand plans?"

The young village chief saw that the tax collector was annoyed, and hurriedly apologized, and said: "My lord, it is the small one who is not thoughtful, and the small one who eats ice mushrooms freezes his heart, but I didn't expect that on this layer, Lord Wanwang will forgive his sins, and the small one will definitely pay you double the tax in the coming year." ”

Lu Jingzhi was amused and said, "I heard that you can last five days of sulfur for one day now, but you only give me double the tax, what is the reason?

The village chief said in fear: "How dare the small one, the adults don't know, this amount of collection is up, but someone has to carry it back." The way to go up and down the mine is far away, and these days there are more people to collect by hand, but there are not many people who have not moved back, and there are few people in the adults, small villages, which are not as good as those big villages. No matter how many things the little ones pick, they have to move them back slowly. ”

Lu Jingzhi thought about it carefully, but he also understood. It's not that the village's production can't keep up, it's that the capacity can't keep up. Because of the need to avoid toxic gases, the village was built far away from the sulfur lake, and it was four or five kilometers away from the collection point. If there is no suitable means of transportation, it is really impossible to rely on manpower to move the collected things back.

"Don't you have a car?" Lu Jingzhi asked in distress.

The young village chief thought for a moment, then remembered, and replied, "My lord, there is one in this car, but it has long been dilapidated and unusable. This was pulled by the former village chief from the distant village of Guomushan. There should have been an animal pulling it, but when they drove it to the lake of brimstone, they smelled the stench of brimstone and refused to go any further. I had to pull a few young and strong laborers together, even if I wasted a little manpower on the mine, I could finally transport things back. However, after a few trips, the wood of the cart became black spots, and after a dozen uses, the axles wore out badly. Before the hundredth time, the frame was unbearable, and it was about to fall apart, so I had to stop using it. ”

Lu Jingzhi knew that what the young village chief was talking about was the corrosion of sulfur dioxide on wood, and the road conditions were not good, so the efficiency of the use of this animal-powered cart was indeed not high.

"Then can you repair it now and continue to use it for a few more trips?" Lu Jingzhi was thinking about the newly mined sulfur ore on the mine, and he hoped to snatch the mine back before the tax collector "over there" came. Otherwise, it is very likely that the villagers in the border villages have just finished helping them increase their yields, and they will change hands and become enemies again.

"Probably not. The young village chief shook his head and said, "The big cart uses a big log from a big tree that is half hugged by one person as a wheel, and there is no such big tree near this small village. I'm afraid that this wheel alone will not be easy to do. ”

Lu Jingzhi touched his chin and stood up, and circled around the broken table of the village chief's house. He learned from his father, his father Lu Feijing was a teacher, and when he encountered a difficult problem to solve, or a student's homework had any difficult problems to deal with, he would touch his chin and go around in circles.

"Take me to see it. Lu Jingzhi said resolutely, "I'm going to go and see how much else there is available in that car." ”

To say that this big car is indeed the real thing. The places that are easy to wear are all good ice fruit wood, and the general places are also hard teak. Only in the places where it is really not too difficult, in order to save costs, pine planks are used, and they are two inches thick. However, although ice fruit wood is hard, it is not corrosion-resistant, but it is not as good as teak. Since the wheel was in direct contact with the ground, it was made of ice fruit wood, which had been corroded to the point of pitting.

"It really doesn't look like it's going to be very useful. Lu Jingzhi muttered quietly, but something is better than nothing, he has an intuition that he should be able to use this big car. So he touched his chin again and circled around the cart. While thinking about it, he suddenly remembered a black mark he had seen on the table of the village chief's house just now, and he suddenly had an idea. In order to verify, he still beckoned to the young village chief and said, "Come here, I have something to ask you." ”

When the young village chief approached, he asked, "Just now I saw a black mark on your desk, there is a ...... It's so big," Lu Jingzhi gestured the size of the young village chief with his hand, and said, "How did that come about?"

The young village chief was worried about himself, worried that the tax collector would not get the tax he wanted, and whether he would be angry with himself or the villagers. ”

Lu Jingzhi waved his hand impatiently: "Who said this, I asked you where that black thing came from, but it was burned?"

The young village chief was stunned for a moment and said: "Yes, my lord, it was a naughty dog in the family, who knocked over the lamp and candle on the table, and burned himself. ”

When Lu Jingzhi heard this, he thought about it, and after a while, he suddenly looked up to the sky and laughed: "Isn't this it?" and shouted: "Go and invite the charcoal craftsman's family to the young master." Be quick. ”

The charcoal maker's family was smoldering with activated charcoal, and when they heard the tax collector's request, they hurriedly left only the youngest child to guard the fire and rushed over with the others.

"I'll give you a big job, and the young master will be rewarded for doing a good job. "Rewarding money is the only magic weapon of the eldest young master of Lu Jinglu, no matter who the other party is. Serious people take the reward money to work, and people with evil intentions take the reward money and go on the road, so it will not be wrong to use the reward money at any time.

The man of the charcoal craftsman's family was a simple and honest man, and he could only live in the village by relying on the young and middle-aged people who could mine, and exchanged the charcoal burned every day for a little food to support his family. However, he has no other ability, so he can only let his son still learn this craft and continue to live a life of burning charcoal to make a living. However, since the tax collector came, he first taught himself to burn charcoal that was full of holes, rewarded himself with a small bag of sulfur, which was enough to replace his family's food for a year, and then made himself a mask to sell to people who went to the mines, making a lot of money.

"My lord, you let the little ones do the work, how dare the little ones reward the lesser money, you have already rewarded enough. The honest man rubbed his hands, no one remembered what his real name was for a long time, everyone just called him Hanzi, called him Daddy, Hanzi Daddy. Now Daddy Hanzi has already contributed his life - he was robbed of his body and soul by the tax, but he has given birth to several little sons. This is how humans live on the territory of the ghost clan.

"The young master wants you to burn this ice fruit wood. Lu Jingzhi pointed to the wheels of the two ice fruit trees of the cart and said: "When you burn it, you can't set the ice fruit wood on fire, but you must burn a layer of black outside, the thinner the better." ”

"My lord," replied the charcoal maker's son, "to burn this, you have to have enough firepower, and you have to be fast." No wood has the same firepower as it does now. ”

Lu Jingzhi smiled and said, "What's so difficult about this? Don't you have charcoal gas when you burn charcoal? Just use that." Do you have an air pump?" Seeing the charcoal maker shake his head blankly, he knew that he was asking too far ahead, "What about the blower? Lu Jingzhi's inspiration flashed, and he suddenly remembered the scene when he went to the countryside to play when he was a child, and blurted out: "Is there a bellows?"

The charcoal craftsman nodded in surprise and said, "There are bellows, every family has them, but that one is used for cooking, can it also burn charcoal? And this charcoal gas is poisonous, and it will poison you if you smell too much." ”

Lu Jingzhi was surprised when he saw the charcoal maker, and he was extremely proud, you burned charcoal for a thousand years, and it was not as good as the young master and I read the book for half a year. With a smug face, he said, "Of course." You connect this charcoal gas into a thin tube with a cylinder, and then connect a cylinder to the bellows, and use the gas from the bellows to spray out of the pipe with the charcoal gas, this thing is very powerful, if you accidentally burn it on your body, you can't ask for it directly. ”

Lu Jingzhi's method is the carbonization technology of wood surface brought from modern knowledge, but he does not have acetylene flame or hydrogen oxygen flame at hand now, so he has to let them use the charcoal gas produced when burning charcoal. In the eyes of the villagers, this charcoal gas is poisonous gas, and if it is not done well, it will poison people. But in Lu Jingzhi's view, this is carbon monoxide at all, as long as it is sealed well to prevent it from leaking, it is not a problem at all, plus operating in an open outdoor area, there is no need to worry about poisoning. As long as you get a carbon monoxide spray gun and make a surface carbonization of the wooden wheel, you are not afraid of corrosion, and the charcoal burned by ice fruit wood is the same composition as other charcoal, but the trace composition is slightly different. Considering that the carbonized surface will become brittle, it is likely to peel off in the process, and a layer of wear-resistant shell is added. Fortunately, the area in contact with the ground is not large, so there is no need to think too much about the cost, so let the villagers crush the broken pottery shards and evenly coat them with a layer of cement to form a protective layer of ceramics.

While thinking about the follow-up treatment, while teaching the carpenter to process the surface carbonization technology of wooden wheels, Lu Jingzhi felt like an engineer on TV. I remember when I was in the third grade, my teacher asked my classmates what they wanted to do when they grew up, and they said that they wanted to be an engineer, but I didn't expect this wish to come true ahead of schedule.

If you want to know what happens next, let's see the next breakdown.
