Ancient Greek civilization is a more ancient topic. When people were looking for the ruins of ancient Greek civilization, they found a very special stone tablet. A maid was serving a wife, and a thing that looked super similar to a modern laptop. It seemed to have a flip-board design and even a USB interface. Until today, scholars studying ancient Greek civilization have no reasonable explanation for this statue.

Then there is an oil painting with a "mobile phone".

This less famous oil painting is a work by Austrian master Miller. It is called "Weekend Morning". It was born in the 19th century, about 200 years ago. In the picture, a man is waiting on the roadside, while the heroine is busy halfway, holding something in her hand that looks like a "smartphone".

Some people say that the heroine should be holding a mirror, and she is also tidying up her makeup and meeting the man she likes.

The journey was mysterious, and no one confirmed that he did not. On January 27, 1995, American scientists discovered that a lot of gray-white smoke was hovering over Antarctica. At first, scientists and meteorologists thought it was a natural weather phenomenon, but it was relatively rare, so scientists fired meteorological balloons and detectors to detect this weather phenomenon.

But what is strange is that when the researchers returned to collect the balloon, they found that the timer of the balloon was actually January 27, 1965.

As I said just now, scientists launched meteorological balloons in 1995, but how could the time on the detector run 30 years ago?

At first, scientists thought it was a machine failure, which led to a time error. However, in the later period, the researchers fired several meteorological detection balloons, but the timer time of each detector would be backed back 30 years. It is understandable that a device has a problem. Is there something wrong with all the devices? This is a coincidence. No one can explain why this matter is so far.

Also, in 1986, when an American pilot was flying a high-altitude reconnaissance plane and flew over Florida to carry out a mission, a light suddenly appeared in front of him. After he recovered, he found that he had come to a completely unfamiliar place, not in the United States at all.

After the pilot came back, he reported that when he was driving the plane was reconnaissance at low altitude, he could feel a wave of huge heat waves, and he could see piles of corpses below, which was shocking and burning.

After the investigation he said, experts believed that what the Air Force pilot saw was the famous Black Death phenomenon that occurred in the history of the medieval European era. The Black Death patients were concentrated to burn and deal with it. The pilot should have missed the space-time tunnel and returned to the medieval European era.

Zhu Lang sat in front of the table and wiped the suitcase carefully. The suitcase was about one meter high and was a rectangular shape. It was very waterproof. After wiping outside, Zhu Lang used a knife to disassemble the suitcase. The inside was not wet, and there was a layer of plastic wrapped inside. Then he opened the plastic. The first thing he saw was a handwritten letter:

Hello, stranger, my name is Zhang Chen... From the 30th century, do you know the Mayan prophecy? Hehe, I can tell you now that there is nothing, but our earth has indeed suffered a devastating blow.

How destructive is it, the entire earth has become a glacier, and humans survive less than one percent.

It was all caused by those foreigners. Because the earth became hot overall, the foreigners began to manually cool the atmosphere. Who knew that the climate became abnormal in this cooling, and the temperature dropped to minus forty degrees Celsius in one day, and it would be a matter of time before humans became extinct.

Fortunately, under such harsh conditions, humans invented a time machine that can go back to the past and change the future. However, the time machine can only return to the earth once. You also know the butterfly effect. The senior management dare not act rashly, worried that it will make the earth worse.

So soon, we had a plan to travel through parallel spaces. Maybe you don’t believe that the space you are in is not the earth, but the parallel space that is almost the same as the earth.

We need to calculate how we should change our return to the earth by changing the history of parallel spaces, but unfortunately, there was a problem with my journey, and the place I traveled through was not the Ming Dynasty in parallel space.

But in the primitive era, because industry could not meet the requirements, all my data was meaningless. This box of information is the books and encyclopedias I brought here from the future, which tells in detail the top technologies in various industries.

There are also drawings and data for weapons of mass destruction such as guns, cannons, and even atomic bombs. The Ming Dynasty must unify the world earlier and then begin to curb the advancement of science, which may prevent the earth from becoming a glacier.

Of course, your parallel space is not the only one. We have sent many people to the parallel space one after another. They have traveled to the Tang Dynasty, some to the Yuan Dynasty, some to the Song Dynasty, some to the Ming Dynasty and the Qing Dynasty, but I am a little miserable. I have traveled to the primitive era, and I really don’t know what went wrong.

And I believe that if something goes wrong here, someone will definitely come to my parallel space, so everything is ready for you. What you have to do is to light up the technology tree in advance. After it is lit, it will curb the development of science and technology. We must continue to continue the monarchy system and not allow the citizen system to emerge.

It is said that the civic system is equal to everyone, that is fartling. Where can everyone be equal? ​​It is just a slogan to fool them. Moreover, the so-called equality of everyone is only darker, especially if you bribe a person and immediately give you a human rights, there is no fairness.

Therefore, we must maintain the monarchy, just like now. Of course, if we encounter a bad emperor, we will be unlucky, but we will not disgust people.

Okay... I have said everything I should say, goodbye, I'll leave the things inside for you. I'm going to go home with my Ayao, Nono. The primitive people really look like orangutans. Ayao is the least similar, but her hair is still vigorous. Sometimes I feel that I am the mother, and provide data well for us humans.

....................................

The letter came to an abrupt end here, and Zhu Lang still couldn't calm down for a long time. It turned out that the place he was in was not the earth, but the same parallel space as the earth. This could explain the development of some things. Those who should have died could survive after their own treatment, and those who could have survived because they could have died early.

Because I don’t have this history, everything I do is to change history. If it is on the earth, then checking Zhulang’s changes may even change myself, but this is in a parallel space, so Zhulang can be scruples without any scruples.

There was no need to bear any consequences, which made Zhu Lang smile at the corner of his mouth. If this was the case, then he would not need to worry about what he would do in the future. And maybe he could also save Zhu Xiongying, Empress Ma, and Zhu Biao.

Zhu Lang felt much better when he thought of this. No matter whether he was the earth or not, it had nothing to do with him. Since he came, he would be at peace. As long as he was still alive, that would be fine. Whether it was not the earth or parallel space, as long as he could feel this reality, that would be fine.

Zhu Lang then took out the things inside, my god, the encyclopedia, I won’t mention the full name of this thing, but this encyclopedia has a total of 77,859 entries, totaling 125.68 million words, covering 66 disciplines and fields such as philosophy, social sciences, literature and art, cultural education, natural sciences, engineering technology, etc.

Among them, light industry, (1) salt extraction, (2) agricultural and sideline food processing industry, (3) food manufacturing industry, (4) wine, beverage and refined tea manufacturing industry, (5) leather, fur, feather and its products and footwear industry, (6) wood, bamboo, rattan, brown, grass products industry, (7) furniture manufacturing industry, (8) paper and paper products industry, (9) culture, education, engineering, sports and entertainment products manufacturing industry and printing of this book, (10) ink, animal glue and

Daily chemical products manufacturing, (11) plastic products industry, (12) glass, ceramic products manufacturing, (13) metal tools and metal daily necessities manufacturing, (14) light industry general equipment and special equipment manufacturing, (15) bicycle, auxiliary vehicles and non-highway recreational vehicles manufacturing, (16) battery, household power equipment and lighting equipment manufacturing, (17) clocks, scale instruments and daily necessities manufacturing, (18) construction and decoration industry.

Hehe...you can't imagine that there is no knowledge that it does not exist, and in addition to these, there are some military weapon design drawings, rifles, machine guns, artillery, gliders, aircraft, gunpowder, etc....!

This is a technological treasure, and with it, the steam engine can be completed in advance because there are detailed steam engine design drawings. Zhu Lang will create more powerful yellow gunpowder, followed by cannons, and conquering the world depends on these two things.

"Okay..." Zhu Lang shouted happily.

Suddenly a little head stuck in. Zhu Lang turned around and saw that it was Zhu Xiongying, then smiled and said, "What are you doing..."

"Grandma asked my uncle to drink fish soup, and my father caught another big fish, which was amazing." Zhu Xiongying smiled.

"Is that right... your father is quite powerful, then go... uncle goes to eat the fish your father caught." Zhu Lang laughed.

"Uncle hug..." Zhu Xiongying stretched out his hand at Zhu Lang, and Zhu Lang directly saw Zhu Xiongying hugging him and said with a smile: "Okay...Uncle hugs you, you little thing."

After a while, the two walked out of the tent and saw Zhu Lang coming out. Zhu Biao immediately shouted proudly: "Brother Lang, come and eat fish. I just caught a big one, which is black fish. Oh, the taste is old and delicious. Come and drink fish soup, the queen mother cooked it myself."

"I understand...Brother, your skills are getting better and better, and you can catch any fish." Zhu Lang held Zhu Biao and heard his younger brother holding him up, Zhu Biao smiled proudly: "That's right, everyone wants to eat fish in the future, tell me... I can catch you all."

"Then it depends on you from now on." Zhu Lang laughed.

Then everyone started drinking fish soup. The group rested for a day in this place. They originally said they would leave the next day, but Queen Ma saw that Zhu Biao really liked this big lake. In order to allow her prince to truly relax, Queen Ma stayed for one more day.

Zhu Lang also agreed because Zhu Lang also wanted to study yellow gunpowder.

British philosopher Bacon mentioned in his book "New Tools": "The three inventions of printing, gunpowder and compass have changed the appearance and condition of things around the world."

However, among these three inventions, gunpowder may be the most "helpless" and great invention of the Chinese. Some people often lament: "Invented gunpowder in ancient China, it is a pity!" It is understandable that people would express such emotions. After all, modern China has suffered too much humiliation in the face of the "strong ships and powerful guns" of the great powers.

On Earth, the West invented modern gunpowder yellow gunpowder in advance. It is a chemically synthesized compound.

"Yellow powder" and "Black powder" have embarked on two different development paths from the beginning. Black gunpowder consists of sulfur, nitrite and charcoal, and undergoes physical reactions after ignition; yellow gunpowder is a compound that causes a series of chemical reactions after detonation.

Judging from the actual application of the two, the power of black gunpowder is far less than that of yellow gunpowder, and it is unsafe, and it is very easy to explode during the transportation process. In ancient China, black gunpowder was also used to make firearms, such as thunder guns, thunderstorm, copper firearms, etc., and were used in military affairs.

Black gunpowder was once used as a launching medicine for guns and cannons in Europe, but it can only be used for primitive guns with limited strength in the Middle Ages, such as muskets, muskets, smoothbore guns, etc., but not for modern guns such as rear rifles and machine guns. Therefore, ancient war guns and modern guns are two concepts.

Now Zhu Lang has obtained the method of making yellow gunpowder, but the road to getting real yellow gunpowder is still very long. Zhu Lang must first obtain sulfuric acid, according to the information left by Zhang Chen.

The methods for producing sulfuric acid include contact method and lead chamber method. The contact method requires platinum, vanadium pentoxide, etc. as catalysts, which Daming cannot do.

The lead chamber method has a glimmer of hope. Because it uses sulfur combustion to produce sulfur dioxide gas, mix it with excess air and water vapor, and then passes into the corrosion-resistant lead chamber, turning it into dilute sulfuric acid, and does not require special materials.

The information tells Zhu Lang that only a ceramic jar for ordinary people to store water or grain, plus a ceramic tube. The water tank is made of hammers and wedges to dig out the required holes, and a pair of water tanks are pinched together, and cast and sealed with lead water at the docking point, which becomes a "reaction chamber". The entire reaction device consists of five reaction chambers, connected with lead pipes in series. These reaction chambers are collectively called "towers".

The first and last towers are equipped with small pieces of coke as fillings for damping. There are two equipment at the front: one is a box made of iron brisket, ignite sulfur, blow the blast with a bellows to produce sulfur dioxide gas, and lead it into the front tower together with excess air; the other is a cast iron kettle, which is filled with tin and sulfuric acid, and after heating, it produces nitrogen oxide gas, which is also introduced into the front tower. After the "equipment" is started, the things that flow out from several towers should be manually poured over, and sulfuric acid should be able to obtain sulfuric acid under the first tower.
