Lu Chen is very busy, after the boycott of the army, he is even busier than the days of the war, so busy that he hasn't done radio gymnastics for a long time, but the little meow with short hands and feet often babbles and plays two sets by Lu Chen's side, but he can only smile and laugh, and he has no time to watch more. Zhen Mi naturally spent a lot of time alone in the empty room, She Zi's health has improved a lot, and she can punch in the small courtyard every morning, I heard that Wuzhu has been beaten by her several times, but Lu Chen rarely sees her. As for Wuzhu, she suddenly became strange now, she hid when she saw Lu Chen, she didn't understand why she was so shy, which made Lu Chen extremely curious, but she didn't have time to study it.

What is Lu Chen busy with?

He was busy drawing the layout of the coal mine, busy sending people to contact and fool the Xiongnu and Xianbei people to transport all the war horses to Mayi to sell, busy digging out the manufacturing process of cement that he didn't know much about from his head, busy urging the former servants and now the Shenhuo Bureau to refine gunpowder and reform the process, busy discussing with the blacksmith how to use coal to smelt steel with better hardness and toughness, and busy choosing the lowest textbooks and the cheapest teachers to open a private school for the children of the workers without money......

In short, every day without touching the ground, so busy that he didn't even have time to sleep, these things could have been done without having to do everything, but Chen Gong and Pang Tong did not have modern knowledge, so he had to lay a foundation first and contribute his few knowledge first.

Lu Chen couldn't be lazy, because time was very tight, he had to do this before Liu Bao came, and then deal with Liu Bao with peace of mind. Taking Liu Bao's clan and territory is the first step for Yanmen to expand and become strong, and it must be completed. And after that. He has more things to do, to unite with the Xiongnu, to provoke Cao Bald and Scar Yuan to fight more hotly, and even to deal with the invasion of the Xianbei people in winter, which is indispensable.

Therefore, the three steps of coal mining, cement, and iron smelting must lay a good foundation before the autumn.

Now Lu Chen found out that in fact, crossing is a very difficult thing, because a person's wisdom is limited after all, and you won't know all the knowledge. Some you know. But I won't do it. In addition to making low-quality gunpowder and purified alcohol, Lu Chen found it difficult to do anything in this era, and a few carloads of saltpeter could be used up to make a few ice creams. Lu Chen didn't dare to eat ice cream, and he would waste money and money? Not really. It's an ice cube made of saltpeter, which has a smell.

Occasional leisure. Think about it. It's still comfortable to set up a stall.

Early one morning, Lu Chen, who had drawn a copycat version of the cement manufacturing flow chart overnight, was just about to sleep for a while when he heard a report from Pang Tong, who was in charge of setting up the iron-smelting plant. It is said that the storage of Yanmen iron is too small, and they have made stirrups and horseshoes, and now there is not enough iron to beat the hammer, how to expand production? Lu Chen's eyes were red like rabbits, and he was crazy for a while, this was a problem. The real problem, Pang Tong said, is that even if the ironworks are done well, the number of blacksmiths is insufficient, and the supply of iron ore cannot keep up, and the mining and transportation efficiency is too low.

The two of them were blind for a while, and Pang Tong said angrily that it was time to melt Gao Shun's hundreds of sets of infantry heavy armor and strike iron. Lu Chen laughed angrily, so Gao Shun would chop Pang Tong up and feed it to the dog, and then chop the dog and braised it.

Lacking everything, this is the most difficult time for Lu Chen and Yanmen.

However, Pang Tong's idea also reminded Lu Chen, and he immediately introduced an almost violent plan "Great War Steel". The content of the plan is very simple, each household will take out unnecessary iron horses, lend them to the government with white slips, and return them twice after half a year.

In Pang Tong's mind, half a year later, the iron-smelting plant began to work, not to mention double, triple can afford it, if the iron-smelting plant can't be run and can't afford it, then naturally there is a problem with Lu Chen's policy, and if Lu Chen solves it himself, it has nothing to do with him, how can he not be happy?

For this idea, Pang Tong clapped his hands and said that Xiaojun Hou's wisdom is unparalleled in the world, there is no one before and no one after him, Yunyun, a fat face is red with excitement, and Lu Chen has solved a big problem for him.

Then, Lu Chen pointed to the sword on the fat man's waist and said, "You took the lead and donated the sword!" ”

Pang Tong was trembling at the time, this is the heirloom sword given by his uncle, if he donates it and returns to Jingzhou, won't his uncle tear him alive?

However, when Lu Chen threw out the simulated version of Fang Tian's painting halberd, Pang Tong had nothing to say.

So, Lu Chen snorted and fell asleep, and Pang Tong began to collect iron horses everywhere, and for a while, the city was full of wind and rain and criing.

Fortunately, Pang Tong is still interesting, or this thing is timid, he just went to some big families and ordinary people's homes, and he didn't dare to go to the official's house to spread wild, after all, to coerce Lu Bu to hand over Fang Tian's halberd or something, he would be cut down on the spot, so Pang Tong didn't go to the family of other civil and military generals, he wouldn't offend people in vain. Although most people were reluctant to donate, Pang Tong asked two soldiers to carry Lu Chen's Fang Tian painting halberd, falsely claiming that it was Fang Tian's painting halberd, and he didn't say that it was Lu Chen's imitation, most people only thought it was Lu Bu's, and all of a sudden, no one dared not donate, and even those Wenchen military generals who had no one to urge them also ordered their families to send some rusty iron tools over.

But all the iron tools that are not necessary in life, Pang Tong accepted them with righteousness and awe, and then secretly drew his sword back and went home to hide. As for Lu Chen's high-imitation Fang Tian painting halberd, he wanted to return it, but in the end, he still melted it in the furnace, why? Who asked Lu Chen to fight Lao Tzu's sword's idea? Besides, give it back to him, he must know that I hid the sword, so that the wise Pang Tong will not expose himself.

As for Lu Chen's move to collect iron scrapers and set up a new iron-smelting factory, there have been various versions of rumors in Mayi.

Rumors are broadly divided into three schools, the War School, the Dark School, and the Mythological School.

The war faction believed that Lu Chen collected iron scrapers in order to build a large number of weapons, and then raise troops to fight. Their reason was very good, because Lu Chen did not have many soldiers and horses, but he heard that the heavily armored trap camp was going to expand from 500 to 5,000 people, and the ultimate goal was 50,000, of course, a lot of iron. Moreover, they also got reliable news that Lu Chen's heavy armored cavalry was about to be released, it was said that people were wearing heavy armor, horses were covered with iron Kai, and the real steel torrent was not much, it was said that it was only tens of thousands.

I have to say that although they guessed outrageously, the news that Lu Chen was going to run the heavy armored cavalry was still true, but they didn't know that Lu Chen had temporarily shelved the equipment and training of the heavy armored cavalry because of the matter of the iron smelting plant.

The dark faction is darker, they say that Lu Chen wants to follow the example of the tyrant Yingzheng, collect the world's soldiers, cast gold people, and weaken Yanmen, so that the people of Yanmen cannot resist his rule. Qin Shi Huang cast twelve iron men, Lu Chen can't compare, one is enough. Such rumors are very unreliable, but there are many people who believe them, and the reasons are unknown.

The mythological sect is more interesting, they claim that Lu Chen is turning iron into gold, secretly collecting many iron horses, and then using the immortal secret method to turn iron into gold. The arguments of this school are even more illogical and ridiculously naïve, but they are the people who believe the most, as if confirming the truth that the more blind they are, the more people will believe. They said that Lu Chen was originally an immortal with spells, and the reasons were also very good, the first was that Lu Chen was stupid and stupid when he was a child, and he suddenly became smart, which is known to the world, and the second is that Lu Chen was able to lead the sky and thunder to bombard the enemy, most of the people in the Yanmen Mayi area knew it, and the third was that Lu Chen could make the stone burn, which was a new spell, which was according to some workers who secretly mined and dug stones in the canyon.

Pang Tong's small actions, as well as outrageous rumors in the market, Lu Chen heard nothing, and buried himself in painting all day long.

After a few days, the painter is good.

However, the painter was not the most important, the most important thing was that he drew a blower, a model of a coal furnace, and a hydraulic press. It's crude, it's just working on the right track, it's working, but it's wasteful, but it's significant.

Among them, the most important is of course the hydraulic press, which will be a great weapon for the ironworks, and in addition to the high-temperature furnaces for coal, it is also another key to ensure that the quality of steel at the Mayi ironworks far exceeds the entire era.

The principle of the hydraulic stamping machine is very simple, that is, to use the water flow to run the waterwheel, and then use the gear principle to slowly make the hammer weighing thousands of pounds too high, and when it reaches a predetermined height, it will fall, impacting the red-hot steel mold below, and its impact force is far from being comparable to hundreds of blacksmiths holding the hammer.

The blower and coal furnace have a great effect on raising the temperature of the molten iron.

Chen Gong Pang Tong and others didn't know how powerful these three inventions were, but after showing them to a few old blacksmiths in the ironworks, they were so excited that their beards trembled, and they even called Xiaojun a pity not to be a blacksmith.

Once the press, coal furnace and blower are ready, the preliminary preparations for the iron-smelting plant are completed, and the iron-smelting can begin when the plant is completed and the ore arrives. But before that, there is a key issue, which is the location of the iron-smelting plant.

In Lu Chen's view, Mayi is surrounded by water on three sides, and the water flow of the moat is gentle, but fortunately, there is a section of the downstream of the river with a large water flow difference and sufficient impulse.

Therefore, Lu Chen chose to build an iron-smelting plant there.

There has been a lot of opposition to this, and the core point is that it is outside the city, and if Mayi is attacked, the ironworks are likely to become the enemy's weapons factory. Lu Chen vetoed all objections, and he only said one sentence: I will not tolerate any enemy army entering Yanmen County, let alone let them attack the city of Mayi.

Within a few days, thick black smoke came out of the buildings of the iron-smelting plant, such as the factory building and dormitory, while the foundations were still being laid. However, the blacksmiths began to make the gears and the thousand-pound hammers needed for the stamping machine according to the drawings, but their enthusiasm was higher than that of Lu Chen and the others, and no one wanted to see the new steel refined with the help of coal and stamping machines more than them.

At this time, the road has just begun to be built for more than two miles, and a construction site can be seen at the head of Mayi City, and the coal mine in the canyon has just been dug up a zhang of thick soil, and the coal is far from being seen. (To be continued......)
