Just when Ashikaga Ikki took the Japanese shogunate envoy and rushed to Shuangyu Port by boat, Zhou Chong also had a lot of happy events, because the European craftsmen he hired had finally achieved success.

First of all, good news came out from the artillery workshop. It turned out that some problems had been improved and can be fired normally. Zhou Chong also rushed over and took a look. It turned out that the range of the Flang machine cannon was about one mile.

Between three miles, this is mainly because with the current technical level, the rear-mounted cannon cannot be completely sealed, and there are always air leakage, so the range is shorter than the front-mounted cannon.

However, Zhou Chong didn't care about this. Originally, he wanted to use the Flang machine cannon on a sea boat. In the bumpy environment of the sea, there was no scientific aiming system and radar, so the cannon could only be fired when it was approaching.

Therefore, the range of the artillery does not mean much. Instead, the Fran aircraft can shoot out three shells in 20 seconds, which is a very advantageous move in naval battles.

Artillery was a project headed by Priest Nader, and it started before the arrival of European craftsmen, so it was not surprising that they were the first to achieve results, but the second to achieve results was not the shipbuilding industry that Zhou Chong was most concerned about.

It is a glass workshop led by two European craftsmen.

Speaking of the various European craftsmen recruited by Father John, many of them have very similar experiences to those of Priest Nader. They have worked in many factories and learned a lot of mixed techniques. Two of them have burned glass in Europe.

This technology is understood in Europe and Central Asia and many people know it, and it is not a confidential technology.

At the request of these two glass craftsmen, Zhou Chong quickly built the glass workshop and found the required materials. As a result, the two craftsmen quickly burned good glass products, but because the raw materials contain iron, they compared the materials.

Because of the height, the glass turns green, but this is not a big problem. Zhou Chong has also read some information about glass in his later generations, so he suggested that two craftsmen use quartz as the main raw material, and then

When firing, a small amount of lead is added, and the most primitive lead glass is burned. It is brighter and more transparent than ordinary glass.

With this original lead glass, Zhou Chong made a concave mirror and then made the telescope. The reason why he rushed so quickly was that Zhou Chong had already included the telescope in the gift list given to Zhengde. Zhengde was fun

He also likes military affairs. It just so happens that the telescope is fun and has great military uses. I believe he will definitely like it very much.

In addition, after having glass, Zhou Chong has been studying how to make mirrors. Speaking of which, although the glass mirrors in Europe have appeared, they have always been in the hands of Venetians, and a mirror the size of a book can be sold in Europe.

More than 100,000 gold francs are simply huge profits. Even smuggling cannot be compared with the speed of snatching money like the mirror.

Speaking of mirrors, the first thing Zhou Chong thought of was the mirror reaction he learned in chemistry class when he was in school. Unfortunately, he did not have silver nitrate or glucose in his hands. As the saying goes, it is hard to cook without rice. Just knowing the method is useless.

Fortunately, Zhou Chong still remembers another way, which is to first apply the molten tin on the glass, then apply mercury and let it sit. After a period of time, the mercury and tin form an alloy that is not easy to fall off the glass.

.However, because mercury is toxic, it takes a certain risk to make a mirror using this method, and even over time, mercury may become poisoned.

However, in order to give Zhengde gifts, Zhou Chong didn't care about so much. He taught the two European craftsmen the method and asked them to study it first. If there were any questions, he could ask himself. As for him, he would never touch mercury himself.

Yes, after all, he and Jinxuan are still planning to have children in the future. If they are exposed to mercury, it is likely that the child will be deformed, and he doesn't have the courage to take this risk.

The telescope and glass mirror, as well as the corn and sweet potatoes prepared by Zhou Chong before, and then some more ordinary gifts were added, but Zhou Chong still seemed a little thin. Finally, he thought about it and simply made the first batch of chili peppers this year.

I took out some of the chili sauce that was made and packed in a glass bottle, and then wrapped it in silk and nanmu boxes, making the chili sauce look very high-end, which makes the gifts more.

In addition to the gifts above, Zhou Chong also has a heavyweight gift. This gift is the newly developed Folang cannon. Originally, due to problems with the development of Folang cannons, Zhou Chong could not guarantee that he would set off.

At that time, how many can these cannons can be made, but I didn't expect that Priest Nader and others would solve the problem so quickly. When he set off, he would definitely be able to cast it better. So Zhou Chong thought about it and simply used this new type of cannon.

Give it as a gift.

Although the range of the Flang machine cannon is not satisfactory, its firing rate is excellent. If it can be equipped with the Ming army, especially the border troops in the north, it will undoubtedly greatly improve the border troops.

Combat power, which will definitely have a lot of advantages when fighting against the Tatars and the Watstorms that are moving south from time to time.

It can be said that in order to leave a good impression on Emperor Zhengde who had met for the first time, Zhou Chong tried his best to make a gift. Although Wu Shan and Ma Liang have always advised him not to care too much about these gifts, as long as he can go to the capital, His Majesty the Emperor will

I would be very happy, but Zhou Chong couldn't believe in Emperor Zhengde's character. This guy is famous for being out of tune. If he didn't do anything well and made the other party disgusted, it would be too unworthy.

, so he would rather be careful now.

That morning, Zhou Chong went to the shipyard to hold a launch ceremony for a newly built blessed ship. This blessed ship was one of the blessed ships he had seen in the shipyard before that were about to be completed.

It was the first completed ship among the batch of lucky ships, and the other lucky ships are about to be completed.

This batch of lucky ships is the largest ship built by the shipyard so far. Each ship is about fifteen meters tall, half larger than the previous cargo ships about ten meters tall. In addition, some places have been jointly improved by Zhou Chong and the craftsmen, so that the

These lucky ships are not only safer, but also faster. Zhou Chong plans to use this ship as one of the main ships used by the Chamber of Commerce in the future.

It is also worth mentioning that Chilava's design for the new ship has also been completed. When the lucky ship in the dock is completed, he will immediately start to build the new ship he designed. Although the new ship is based on the Clark ship,

However, it combines many shipbuilding technologies in the Central Plains, and coupled with some improvement suggestions put forward by Zhou Chong, this new Clark ship is faster and more stable than the old Clark ship, and it is much easier to operate. Both sides of the hull

Multiple artillery can be placed, which can be said to be very similar to later sail battleships.

As the designer of this new type of ship, Chilava naturally has the right to name it. After thinking about it for a few days, he discussed it with his wife and daughter, and finally decided to take out the last syllables of his and his wife Helen's name and combine it.

The name of this new ship is translated as the Valen ship, which sounds somewhat similar to the Galen ship in later generations, but Zhou Chong believes that this ship is better than the Galen ship.

After the first Dafu ship was launched, Zhou Chong named the ship "Nanyang". When he went out in the future, the Nanyang will be his specific ship, and during this time, the Nanyang will speed up the trial voyage and wait until he

When he went to the capital, he would take the Nanyang River to the capital by sea.

After the Nanyang was launched, the vacant dock was immediately drained and then prepared to lay the keel of the Valen ship. However, this was not an easy task, and it would take at least a few days to prepare, plus the continuous progress of Chilava and others.

He was busy directing the craftsmen to work, so he had nothing to do, so he came back without having dinner at the shipyard at noon.

When Zhou Chong returned home, he happened to see Jinxuan, Cheer and Bai Mengwan were entertaining Miss Qianla, which was not actually considered hospitality. Since Qianla came to visit last time, she has become the three girls of Jinxuan.

Good sisters, as long as she has time, she will come to find them, and stay for a whole day, and eat lunch at home. Sometimes Zhou Chong feels that there is another bite of people in his home.

"Xi La, what did you learn from Jin Xuan and the others today?" Zhou Chong looked at Xi La who was using chopsticks with a good look and asked with a smile. Xi La always admired the culture of the Central Plains and wanted to make one.

The real Central Plains woman, so she has been learning the skills of Central Plains women from Jinxuan and the others during this period, such as female workers. Last time, she stabbed her ten fingers in order to learn embroidery.

Qianla has long been used to eating here, so she has no special expression on Zhou Chong's arrival. She stretched out her chopsticks and held a piece of her favorite tofu into her mouth. She ate and said, "Today

I learned to cook from Jianer, and also started to learn to recognize words. I believe that in no time, I will be able to understand the contents in the book!"

"Recognize words? This is a difficult task. You have to be prepared for hard work." Zhou Chong said in surprise when he heard this, but he was not optimistic about Xila's preparation for literacy. Daming still used it.

Traditional Chinese characters that are more difficult to write not only have many strokes, but also have very similar shapes, so you may admit your mistakes if you are not careful.

"By the way, which of these are the dishes you cook? How about let me taste them?" Zhou Chong washed his hands and sat down, then smiled at Qianla, but as soon as he said that Jin Xuan next to him was

However, the three girls all laughed out loud, and Qianla also showed a embarrassed expression on her face.

"What's wrong? You can't burn my kitchen, right?" Zhou Chong looked at the expressions of the people and joked. However, as soon as he said that, Jin Xuan and the others showed a bit of weirdness on their faces.
