I watched Er Chuang’s short video, and everything went numb!

The plane of Ming Taizu.

Zhu Yuanzhang also had a look of shock on his face.

The power shown by the Dragon Kingdom in Chengdu in the future, let alone Zhuge Liang during the Three Kingdoms period, went to the Northern Expedition. Even if he came to fight against the Ming Dynasty today, he could not imagine that the Ming Dynasty would have any chance of winning.

This is truly the ability to defeat a country with the power of one city.

"How powerful will the Dragon Kingdom be in later generations?"

Zhu Yuanzhang was very curious.

In other dynasties and planes, many other emperors had the same feeling.

【Chengdu is not only a big city, but also one of the centers of Dragon Kingdom's"strategic backup"】

【The dispersed industrial system along the Chengdu-Kunming Railway, with the Bao-Chengdu-Kunming line as the main body, the Hengduan Mountains, can ensure that the Dragon Kingdom will not lose its most basic industrial capabilities and can still fight a modern industrialized war under a comprehensive nuclear attack.】

【Such a city was given to Zhuge Liang as a whole. Really, let alone the Northern Expedition, the whole world will have to plant the flag of Shu Han.】

"Giving the Prime Minister Chengdu City is a bit too much. I feel that giving the Prime Minister Wuhou District can win."

"Take the hot weapon and you will be a heavenly soldier and a heavenly general!"

"The main thing is that the supporting industry chain is complete"

"Trivia: Chengdu has a complete nuclear industry chain"

"It's upstairs, that's not necessary, right?……"

"……" soon.

This video plays, and a new video appears on the giant screen.

【Essential knowledge for time travellers】

【Today, I would like to introduce to you some must-haves as a time traveler.technology】

【First, indigenous cement manufacturing techniques】

【We have all heard the old saying, if you want to be rich, build roads first. Good road transportation infrastructure construction is crucial to economic development】

【Therefore, if you master the art of making local cement, then if you travel to ancient China, you will have mastered a technology that can make you rich.】

【Cement is known as one of the greatest inventions in human history】

【With it, whether it is military or civilian construction, there will be earth-shaking changes. It is a technology that all time travelers must master if they have the ability.】

【For example, I once read in a time-travel article that the time-traveler made his first fortune after traveling to the Tang Dynasty by cooperating with Li Er to develop cement roads to collect tolls.】

【This is indeed a good 14th road. A product like cement road, in ancient China, would be a dimensionality reduction attack.】

【Of course, to take this route, you have to ensure that your status in the past is relatively noble, and you have to be a wise king like Li Er, otherwise you have to be careful of being hacked. (Dog Head)]

Along with the narration and subtitles, a picture of a smooth, neat and straight cement road appeared on the giant screen.

This picture immediately attracted great attention from emperors of all dynasties.

In the previous short videos, they saw that the roads in the Dragon Kingdom in later generations were so smooth and straight. At that time, they were curious about how such roads were built?

When they heard what the video said, they knew that this kind of road was called a cement road.

In an instant, they all began to stare at the giant screen attentively

【Putting cement roads in the ancient Chinese environment where most roads were loess roads would definitely be a dimensionality reduction blow.】

【To give a simple example, the loess road is uneven. Not only is it full of potholes, it is also very soft. When a heavy truck transporting goods runs over it, it will form ruts and the speed will be even slower.】

【What's worse is that once it rains, the loess road will turn into a quagmire. Once the big car gets stuck, it will stop working completely. Basically, it can only be pushed by many people with brute force, and in most cases it cannot be pushed. ]

Many ancient people from all dynasties felt deeply about these words.

In ancient times, except for the core roads in big cities, which were brick and stone roads, most roads were dirt roads. Once it rained, it would be really miserable.

【In contrast, cement roads are smooth and hard, allowing carriages to run faster while bearing more weight.】

【For example, it used to take ten days to reach a place using a loess road, pulling a carriage carrying 500 kilograms of cargo, but it only takes 5 or 6 days to reach a place using cement roads, even if it is pulling a 1,000 kilograms of cargo. 】

Hearing this, many ancient people in Lili were shocked.

What does it mean to transport more in less time? It means saving a lot of money and resources!

Whether it is for the court or ordinary businessmen, it is a great good thing.

The plane of the Great Ming Dynasty's ancestors.

Zhu Gaochi said to Zhu Di in a deep voice:

"Dad, if this cement road can be built, we will build it tomorrow!"

He is responsible for handling the specific internal affairs of the Ming Dynasty and settles accounts very quickly. If the cement road really has such an effect, it is completely worth building.

Needless to say, his father Zhu Di thinks about attacking the northern Tatars and other nomadic peoples every day. If The road that transports the army's logistics supplies and food is this cement road, so I don't know how much time and loss it will save.

God knows how much he was worried about Zhu Di going out to fight. Zhu Di spent all his money in the war!

Zhu Di nodded.

In In other dynasty planes, many emperors made the same decision.

If the cement road is really so good, it really should be built!

【Moreover, the cement road is not afraid of rain. Even if it rains, it will not be deformed in any way. It is also easier to repair. If it is damaged, just use new cement to repair it.】

【well, let's get back to business】

【Below, I will introduce to you the simple production technology of cement for your reference. If you have different ideas, you can leave a message in the comment area for discussion.】

"Quick, write it down! Don’t miss anything!"

Many emperors in the past dynasties shouted loudly and ordered

【The manufacturing methods of cement are similar and the principles are the same.】

【In the early days of starting a business, I recommend you a simple method of making cement using local methods.】

【First, choose raw materials. You can use clay bricks, various pottery fragments, various ceramic dishes fragments, and various refractory materials, such as fragments of jars, basins, etc. These materials can be taken individually for 75%, or they can be mixed for a total of 75%%】

【Second, take 20% to 25% quicklime%】

【Third, plaster of paris. Grind gypsum ore finely, heat it in an iron pot to 130 to 180 degrees and stir-fry until it is yellowish gray. It is used to adjust the cement solidification speed. The proportion used is about 5% or less.】

【You can omit this gypsum, but it will affect the cement quality to a certain extent. If possible, it is recommended to add it.】

【Wash the above raw materials, dry them in a fire pit, and grind them into powder. You can grind them separately and mix them together according to the proportions, or you can mix them together according to the proportions mentioned above and grind them together.】

【Then what you get is cement】

【Mix cement and river sand in a ratio of one to three, add an appropriate amount of water and stir to get cement slurry that can be used to build roads or other buildings.】

"Cement is indeed very important and has many uses"

"Don’t use too much gypsum as it will reduce strength"

"In fact, I personally suggest that it is best to use the firing and mixing method, which is to soak the sun-dried plant ash in water, pour out the impurities floating on the water surface, then make it into modules and calcine it, then soak it in water and stir evenly, and finally mix it with the sun-dried earthenware. Powder, also in a ratio of 7:3"

"The most convenient way is to use volcanic ash, which is found in the crater."

"Is grinding flour a problem?"

"Water-powered millstones seem to have existed in ancient times"

……"

The plane of Taizu of the Ming Dynasty

"Write it all down! Write down all the information related to the item cement!"

Zhu Yuanzhang said in a deep voice.

He believed that as long as he wrote down all the methods mentioned by these later generations and tried them one by one, he would eventually be able to successfully create cement.

In other dynasties and planes, other emperors also had the same confidence.

In such a large dynasty, there are naturally many skilled craftsmen. Now that we have a specific research direction, it will be much easier. If we try a few times, we will always succeed.

【The following is an introduction to the second necessary technology for time travellers: yellow mud water decolorization method to make white sugar】

【Sugar has been an important strategic material since ancient times. 】(To read exciting novels, go to Feilu Novel Network!)

【If you traveled back in time to ancient times, sugar making would be an effective way to earn your first pot of gold.】

【Today I will introduce to you a method of decolorizing white sugar using yellow mud water.】

【Let me explain in advance that this method of making sugar has been widely used during the Jiajing period of the Ming Dynasty. If you have traveled to this time, you don’t need to learn it.】

【Before the large-scale application of this method in the Ming Dynasty, ancient China mainly used red (black) sugar.】

【The sugar produced by using the yellow mud water decolorization method has the appearance and taste to rival the ancient Chinese brown sugar. It is also better than rock sugar, the so-called"stone honey".】[]

【Before the modern industrial sugar decolorization, this manual sugar decolorization technology was the best way. 】

The plane of Emperor Taizong of the Tang Dynasty.

Li Shimin shouted:

"Come on, get a pen and paper quickly and write down the sugar making methods!"

When he sent Wang Xuance as an envoy to Tianzhu for the second time, the main purpose was to obtain Tianzhu's sugar-making method.

But he didn't expect that in the process of finding the sugar-making method, Wang Xuance destroyed Tianzhu by the way. It was quite unexpected.

Even though he was so far away, he had to send people to learn how to make sugar.

Now that he heard that there was a better way to make sugar, of course he couldn't miss it. Whether in modern times or in ancient times, people have a great demand for sugar.

At this moment , in many planes throughout the ages, many people immediately picked up paper and pen, preparing to record

【The first is the raw material sugarcane, which has been cultivated in China for thousands of years. In ancient times, it was called Zhuzhe, Zhucane, dry sugarcane, etc.】

【The second step is to squeeze a large amount of sugar cane into juice. If possible, it is best to squeeze it three times.】

【The third step is to put the sugar cane juice into a vat, boil it over fire into a yellow-black syrup, and then wait for it to condense into brown sugar.】

【In the last step, use yellow mud water to pour out the brown sugar in the funnel. The black residue flows from the funnel to the bottom, leaving white frost in the funnel. This is the earliest white sugar.】

【Is not it simple?】

【Once this technology is revealed, there is no threshold. Therefore, if you travel through time, you must pay attention to keeping the technology confidential.】

【Next, let’s talk about the last few technologies】

【Compared with the previous two technologies that focus on people's livelihood, the following technologies are military technologies. If you have traveled through the past, there is noOnce you reach a certain position, it is best not to take it out easily, otherwise your life will be in danger. (dog head)】

【These three technologies are: gunpowder granulation, mini bombs and paper shells.】

【In the early days of the firearms age, they were able to greatly increase the power of firearms. 】

The Great Ming Dynasty Chengzu Plane

"Quick, Zhanji, take a pen and paper and quickly write down everything that the next generation says. Don’t miss a word!"

Zhu Di ordered Zhu Zhanji in a hurried tone.

His face was very excited. He really had a pillow when he fell asleep.

He had just made up his mind to vigorously develop firearms in the Ming Dynasty, and now he can get more advanced firearm technology. This is natural. He was extremely excited.

Compared with Zhu Di's surprise, Qianlong was extremely frightened in the Qianlong plane of the Qing Dynasty.

He was very clear about the power of firearms.

They began to vigorously develop firearms early in the morning before entering the customs. , does not lack the understanding of the power of firearms.

But it is precisely because he knows that firearms are very powerful that he is wary of them.

The number of their Manchus is far less than that of the Han people. Once firearms develop in large quantities, the Han people will have A large number of firearms would pose a serious threat to the rule of the Manchus!

Firearms are different from the mounted archery that the Manchus are good at. They do not require long-term and large-scale practice, but only require a little practice for a period of time before they can use them.

Although they were Qing Dynasty It has been a long time since he entered the customs, but the voices of the people against the Qing Dynasty and the Ming Dynasty have never stopped.

Once these opponents obtain firearms in large quantities, it will be a big trouble for the Qing Dynasty!

Thinking of the thousands of Han people possessing firearms, Qianlong felt fear

"No firearms! Han Chinese must be prohibited from using firearms!"

Qianlong made a decision in his heart that he was determined not to allow the Han people to use firearms. Even in the army, firearms could only be used by the Manchuria battalion.

But soon, Qianlong became distressed again.

Now this high-altitude giant screen openly showed firearms technology to The whole world was announced, how to deal with it?

Qianlong couldn't think of a solution, and he suddenly became extremely irritated.

Looking at the giant screen, he felt a little uncomfortable. He felt that this giant screen was always against them, the Qing Dynasty 343

【Black gunpowder, as everyone knows, was invented by me in China】

【During the mid-Tang Dynasty, a Taoist priest recorded the preliminary formula in"The Synopsis of Zhenyuan Miaodao". At the end of the Tang Dynasty, black gunpowder was initially used in the military. However, the proportion of black gunpowder at that time was not good and the power was too low, so it could only be used for arson.】

【In the Song Dynasty, this formula was further developed and various tubular firearms began to appear. By the Ming Dynasty, the black powder formula was very close to the standard proportions.】

【That is, mononitrate, disulfide, and charcoal, 75% saltpeter, 10% sulfur, and 15% charcoal are ground into powder and mixed together to form black gunpowder.】

【Of course, this is just theory. In fact, due to different raw material impurities, the formula ratio will be different and needs to be flexibly adjusted in actual application.】

【During the transportation process, the mixed black powder will easily stratify again and become unusable. Moreover, the powdered black powder is easily squeezed together when it is stressed in the barrel, so that it will be unable to fire due to lack of oxygen during ignition. Burn completely, which greatly reduces the power of gunpowder. 】

The plane of the Ming Dynasty’s ancestors.

When Zhu Di heard this, he couldn't help but nodded. He heard from the general of the Shenji Camp that this was indeed a problem they encountered in the actual use of their Daming firearms.

He also ordered the imperial craftsmen to find a solution, but there was no solution.

"What's the solution?"

Zhu Di looked at the giant screen intently, and emphasized to Zhu Zhanji again, asking Zhu Zhanji to record it carefully and not to omit anything.

【The small trick of gunpowder granulation can solve this problem.】

【The basic method is to grind the charcoal first, then add sulfur and mix it. Put these mixtures into another container, then add nitrate, and add glutinous rice soup to make the moisture content between 4.5% and 6.5%.】

【Of course, in ancient times, there was a lack of precise measurement tools, so you could experiment many times to find the best ratio of adding glutinous rice to soup.】

【Grind the mixture with wooden sticks, wrap the finished product with cotton cloth, clamp it with an iron plate and squeeze it, then crush it to the required particle size, and then dry it to obtain granulated gunpowder.】

【This kind of granulated gunpowder is easy to transport, more powerful, and can also reduce launch costs.】

"Is this how it was solved?"

Zhu Di was quite surprised.

He did not expect that a big problem that troubled the Ming Dynasty firearms could be solved so easily. This is also true. Gunpowder granulation is not a very advanced technology. In the middle and late Ming Dynasty, there was a weapons bureau The craftsmen found this method

【Next, let’s talk about Mini bullets and paper-cased fixed-loading bullets.】

【We all know that the development of firearms is inseparable from the development of modern industries such as the metal processing industry and the chemical industry. It is not easy to achieve a big leap forward.】

【However, there are two technologies that can allow us to double the power of firearms under the simple conditions of ancient China. They can be used perfectly even on matchlock guns, which are bird guns in the Ming and Qing Dynasties. That is the Mini bullet. Custom-loaded ammunition with paper shells. 】

Hearing this, Zhu Di became more and more excited!

He is now obsessed with vigorously developing firearms!.
