The Yamen is one of the most filthy places in the whole world, and to a certain extent, the Qinglou Chu Pavilion is cleaner than the Yamen. Just like the first impression of the government compound in the minds of many ordinary people in the 21st century, it is not that the people inside are working hard, but that the people inside are fighting one by one, praising the high and stepping on the low.

The county government in this era is no different from the government compound in the 21st century, and none of the people in it are clean.

Taking Lushan County as an example, when Yue Wenhai first arrived, he fought with the then lord Bo and Dian Shi for a while, and he finally flattened the entire county government by relying on his position and skills, and was not placed in the main hall as a puppet. This is not only because Yue Wenhai is the master of the county, but also because he has scheming and means.

Without these, no matter how old Yue Wenhai is, he is also at the mercy of the lord Bo and the canonical history, as well as the officials of the entire county government, and can only become an ornament that cannot be a master in Lushan County. Of course, Yue Wenhai's master also has a corresponding level.

Therefore, being an official must not only do a good job in the eight articles, but also have a flexible brain and a plan in mind.

This is the scene staged by the Lushan County Ya back then.

A county official, up to the county order, from the middle to the chief and the history, down to the three classes and six rooms of the wardens, the head catcher and the ordinary officials, everyone is a part of the 'right', and everyone is trying their best to grab more rights. Until the dust settles, the whole county government will become very 'harmonious'.

Therefore, Lushan County is the place where Chen Ming really practiced, as long as he can mix like a fish in water here, then Chen Ming can be familiar with the rules and regulations of the current world of the entire Qing Dynasty.

And the people in the county government, just like the corrupt officials in the 21st century, will be wronged if they are all killed, and some individuals will not die for their crimes [but they are not guiltless]; If you kill one by one, there will definitely be fish that slip through the net.

There, the open and secret battles between the county order and the small officials below, the intrigues between the three classes and the six room officials, no matter how pure white the child is thrown in, it will not be gray in less than a year. In the general environment, you have to compromise with the general environment!

Want to be on your own? Haha, the cliff shore is arrogant, that is the choice of the strong. Little officer, what right do you have to say 'no'? You can't do anything. If you don't want to die, you don't want to be kicked out of the yamen like a dog, so you can only be with the light and dust, and integrate into it is the right way.

The patriarch of a powerful family never needs a righteous gentleman.

The Chen family, who was born as a soap household servant and was engaged in the business of smuggling and selling salt and iron, really wanted to let a righteous gentleman take charge of the family, and I was afraid that it would not take a few years to bring the good Chen family to hell.

Since it's black from the bones, isn't it a joke to still think about whitewashing? Of course, Chen Ming would never have imagined that because of the Chen family's origin as a hereditary soap household selling illicit salt and iron materials, in the era of the rise of the Internet more than 200 years later, it was sprayed by countless disgruntled young people in Europe as a 'greedy and despicable smuggler family, and those with low social status can only be ranked with prostitutes and beggars'.

Xiaonan Mountain is seventy miles to the west.

In the green mountains and clear water, on a hill that is not too high, but there are overhanging walls on both sides, a well-groomed cottage is crowded with people, Chen Ming happily patted the iron cannon next to him that was still emitting heavy gunpowder smoke, and looked at the mountain in front of him expectantly.

This is the small cannon that the Chen family has just cast, and it uses an absolutely unique iron mold casting method in the world at this time. Compared with the traditional clay mold, the benefits of the iron mold are needless to say [in many N novels, the iron mold casting method is an artifact]. But that doesn't mean it's really that magical.

The disadvantage of the iron mold is that from the point of view of metal casting and metallography, the heat dissipation of the iron mold is too fast, which makes the molten pig iron have a large problem of supercooling during cooling, and the cementite in the molten iron has not had time to precipitate (graphitization has not had time to proceed) and the graphite has solidified, so the cementite in the iron mainly exists in the form of iron carbide, that is, white iron. Of course, due to the large degree of supercooling of the molten iron during the solidification process, the metal crystalline particles on the surface are relatively dense and the body tube is relatively smooth;

But this is not an advantage over the iron cannons of the West, which are dominated by gray iron.

The only benefit of the iron mold is that it speeds up the production rate and does not have to wait for months like a clay mold cannon. However, the whiteness of the products of the iron mold cast cannon is very serious, because the cooling speed is too fast, although it is relatively smooth, but almost all of the white iron is generated, which leads to the increase of brittleness of the gun body and the decline of the performance of the gun. In order to increase the tensile strength, it can only be solved by stacking the mass by quantity, that is, by increasing the wall thickness.

The current two-pound cannon can be said to be on the same level as the three-pounder cannon in the West in terms of the weight of the shell, and the weight of the cannon body alone has reached 220 catties [Qing catties], which is close to 270 catties if it is replaced by city catties. I don't know how much heavier it is than the three-pounder gun in the West.

Chen Ming knew very well what the flaws of this iron cannon were, but he couldn't improve it. At his level, it's okay to read from the book, and it's better to wash and sleep to improve it. With the current conditions of the Chen family, the internal mold water cooling technology cannot be thoroughly understood, and the only thing Chen Ming can use is pig iron refining.

This is the method of the British man-made iron cannon.

First use the blast furnace to smelt raw iron, cool into white iron ingots, because there are more impurities in iron smelting, so the iron ingots should be smashed into the reverberatory furnace for refining (do not stir, otherwise the pig iron will be decarburized, without hot blast technology, the furnace temperature can not reach 1538 degrees of the melting point of wrought iron, will produce colloidal wrought iron), after melting, remove the surface slag, so that the molten iron after the second smelting is more pure. In addition, the iron used by the British iron cannons should be smelted with charcoal to reduce the addition of impurities such as sulfur and phosphorus (the British cast iron must be charcoal iron, at the cost of high cost, and the domestic forests are almost cut down), or the iron ore itself contains almost no sulfur and phosphorus (such as Sweden's high-quality iron ore), which is difficult for the Chen family to achieve completely. Although there was no shortage of wood in the Funiu Mountains, the Chen family opened private mines and built stockades in the mountains, and also cut down a large amount of wood. In addition to the logs used to build stockades and houses, the rest is mostly used to burn charcoal, how much material can be used in the mine?

Anyway, Chen Ming is to provide the best conditions for these bell craftsmen as much as possible, and the two-pound cannon he made is still heavy, which makes him frown. Fortunately, he was very satisfied with the range, and it was estimated that there would be a mile of land just now.

In this uninhabited Funiu Mountain, since last winter, the Chen family has been moving people to the mountains little by little, single people and those with families. The Chen family's original two private mines, with only 300 people combined, are now close to 1,000 people. After deducting 2,300 women, children, and children, the number of workers has more than doubled. What's more, the Chen family also drew people from it to organize a 200-person mine protection team.
