As Zhang Jimeng talked, he drew a diagram on the whiteboard.
After looking at the schematic diagram drawn by Zhang Jimeng, Chongzhen felt something in his heart and said: "Zhang Qing, I have a better idea. Why not combine the cork and the blooming bullet into one?"
"Integrate into one body?" Zhang Jimeng said, "Your Majesty said, embed the blooming bullet into the cork?"
"That's what I mean, but it's not a simple fitting." Chongzhen said, "What I mean is to make the body of the explosive bullet into a long cylindrical shape, but the head is forged into a pointed cone shape."
While talking, Chongzhen also drew a diagram on the whiteboard.
"Also, a trigger fuse can be installed at the pointed cone of the explosive bomb."
"In this way, as long as the sharp point of the explosive bomb hits the ground or the target, it can cause an explosion. Wouldn't it be safer to install both a trigger fuze and a delayed fuze on the explosive bomb?"
"This method is good." Zhang Jimeng nodded repeatedly.
"Such a trigger fuze can just make up for the shortcomings of the delay fuze, because it is difficult for the delay fuze to ensure that the bomb will explode immediately after landing. Sometimes it will explode in advance at high altitudes and fail to explode the enemy. Sometimes it will not explode after landing, and the enemy will
You have already run away in advance, so you don’t have to worry about triggering the fuse.”
Smiling, Chongzhen continued: "Changing the spherical explosive bomb into a cylindrical shape has another advantage, that is, more smokeless gunpowder can be installed inside the bomb body, and the surface area of the cylindrical shaped bomb body is larger, which is easier to explode.
Then more fragments can be formed, causing greater damage."
"Oh, right." Zhang Jimeng nodded repeatedly.
"I'm afraid it would be more than twice the number of fragments."
After another pause, Chongzhen said: "Of course, this is not the most important thing."
Zhang Jimeng was stunned when he heard this and asked blankly: "Is there anything more important?"
"Of course." Chongzhen said with a smile, "What's more important is that after integrating the blooming bullet and the cork, a complete bottom concave bullet is formed. If several riflings are drawn in the barrel, its range can be
Double the increase!"
Compared with smoothbore guns, rifled guns not only have a longer range, but also have higher accuracy. There is no comparison between the two.
Hearing this, Zhang Jimeng could no longer remain calm and almost jumped up: "I'll do it now!"
"Hey, don't leave yet." Chongzhen couldn't laugh or cry. He was another scientific madman. After getting a good idea, he would try it immediately, not even wanting to waste a second.
"Your Majesty, if you have anything to say, please tell me quickly. I'm in a hurry."
Zhang Jimeng's mind was obviously no longer in the duty room of the Firearms Department.
Gao Qiqian, who was standing next to him, was dumbfounded when he heard this, and thought to himself: Why are all these people like this? None of them consider Long Live Lord as their emperor, right? Long live Lord is easy to talk to, so they all climb up the pole, right?
But having said that, these crazy and rebellious people seem to have been spoiled by Master Long Live.
Because after being contradicted by these crazy people, Long Live Master, instead of getting angry, he looked very happy.
Chongzhen said helplessly: "What I want to say is that this is just a stop-gap measure. Fitting the warhead and cork together will eventually have adverse effects on the flight of the cannonball, such as unstable ballistics, shorter range, etc."
, so the firearms department had better develop a gunpowder that is not afraid of high temperature and high pressure."
In Chongzhen's memory, the reason why later generations of explosives were not afraid of high temperatures and pressures was because they were mixed with a passivating agent, but Chongzhen had forgotten what kind of passivating agent it was.
After a pause, he added: "You can ask Pascal for help with this matter."
"Accept the decree." Zhang Jimeng bowed his hands and turned around to leave in a hurry.
It was obvious that Zhang Jimeng didn't take it seriously at all.
Chongzhen had no choice but to give up. There was no need to rush these things and had to be done slowly.
What's more, the climbing speed of the Ming Technology Tree is already fast enough.
He crossed over from the 17th year of Chongzhen. This year is the 22nd year of Chongzhen. Now the army of the Ming Dynasty has used rifled guns and smokeless gunpowder, and the navy has been equipped with ironclad ships.
The Ming Dynasty also launched the first industrial revolution.
This speed can no longer be faster.
There is no rush to click on the technology tree, but we must pay close attention to the slave labor issue.
At that moment, Chongzhen ordered Gao Qiqian: "Gao Banban, go to Kang Mansion and ask Kang Shaojing to issue an announcement asking representatives of chambers of commerce from eight prefectures and one state in the south of the Yangtze River to hold a meeting at the Market Exchange in seven days."
…
Gao Qiqian received the imperial edict and left in a jittery way.
After Chongzhen finished handling urgent matters, he returned to the naval base outside Dinghuai Gate again.
When entering, I saw Zheng Zhilong leading a group of naval officers to make plans in the huge official hall. Maps of the Japanese state were placed on the entire north wall of the official hall and on the rectangular table in the middle.
From here, we can see that Zheng Zhilong has not done nothing in these years.
Zheng Zhilong at least drew maps of the coastal countries or islands such as Korea, Japan, Luzon, Cochin, Siam, Myanmar, Laos, and Java, which can be considered as preliminary preparations.
"Your Majesty." Zheng Zhilong saw Chongzhen and hurriedly came forward to greet him.
"No need." Chongzhen waved his hand and asked, "Have you chosen your target?"
"Back to the Holy Spirit, we have already chosen a target." Zheng Zhilong said happily, "Nagasaki."
"Nagasaki?" Chongzhen's only impression was that he and Hiroshima were hit by the atomic bomb together. He had no other impressions. He asked Zheng Zhilong immediately, "Why did you choose Nagasaki?"
"Your Majesty, there are three reasons for choosing Nagasaki." Zheng Zhilong said.
"First, Nagasaki is located in the westernmost part of Kyushu Island, far away from the Tokugawa shogunate in Edo, so even if it is attacked, the Tokugawa shogunate will not be able to mobilize a large army to come to the rescue in a short time."
"Secondly, I have lived in Nagasaki for many years and am very familiar with Nagasaki, and my second son is in Nagasaki. If I attack Nagasaki, my second son and the samurai of the Tagawa family can serve as internal agents, and it is not necessary to capture the city.
Disaster."
"Third, Nagasaki was the only foreign trade port of the Tokugawa Shogunate."
"As a result, merchants gathered in the city, and all kinds of goods from the east and west oceans were extremely rich."
After all, he was a pirate, and he never forgot his old profession of robbing families and homes. After hearing Chongzhen talk about attacking the Japanese country, Zheng Zhilong immediately thought of going to Nagasaki to do something big.
This chapter is not over yet, please click on the next page to continue reading the exciting content! Zheng Zhilong even has a hidden goal.
It would be best to seize Nagasaki and make his second son Shichizaemon Shikawa the lord of the city.
However, Zheng Zhilong's plan was poured cold water on by Chongzhen.
Chongzhen asked Zheng Zhilong: "Mr. Fujian, what is the population of Nagasaki City?"
"The population is not very large, but it is still quite large." Zheng Zhilong said, "About 50,000 to 60,000 people."
"Only 50,000 to 60,000 people? This is too small." Chongzhen said, "Let's find a big city with a larger population."
Zheng Zhilong was stunned when he heard this, and said with some disappointment: "In this case, there are only three places: Edo, Kyoto or Osaka, because the other cities are not much different from Nagasaki, with a maximum of 50,000 or 60,000."
Chongzhen said: "I remember that Osaka should be not far from the seaside, right?"
Zheng Zhilong smiled and said: "Your Majesty, Osaka is actually right on the seaside."
"So, what about Kyoto?" Chongzhen asked again, "It's not that far from Osaka, right?"
"It's less than a hundred miles." Zheng Zhilong replied, "If we march urgently, it will only take one day."
"Then let's conquer Osaka." Chongzhen said decisively, "If possible, conquer Kyoto as well. Even if there is no chance of conquering Kyoto, Osaka's population should be worth the return ticket."
After a pause, he asked again: "By the way, how many people are there in Osaka?"
"No less than two hundred thousand." Zheng Zhilong paused and said, "Your Majesty, I have something I don't know whether to say or not."
After obtaining Chongzhen's permission, Zheng Zhilong added: "During the Toyotomi Hideyoshi era, Osaka was the de facto capital of the Japanese kingdom, and the Toyotomi clan built Osaka Castle on the basis of the old Ishiyama Honganji Temple. The city was extremely strong, although
Later, it was conquered by the Tokugawa clan, but after the Toyotomi clan was destroyed by the Tokugawa clan, Osaka Castle was reinforced and became the territorial domain of the Tokugawa clan, which means it was under the direct jurisdiction of the Tokugawa shogunate."
Chongzhen said: "So? What do you mean, Duke of Fujian?"
Zheng Zhilong said helplessly: "I want to tell the Holy One that Osaka Castle, as the territory of the Tokugawa shogunate, will be heavily guarded. With the heavy troops and the fortified city, it will be very difficult to conquer in a hurry, and once a war breaks out,
If we get into a stalemate and the Tokugawa shogunate summons 80,000 bannermen or even hundreds of daimyo to come to our aid, we will be in big trouble."
"The banner?" Chongzhen asked again, "I know the name, it is equivalent to the princes, so what is the banner?"
Zheng Zhilong said: "The samurai who directly belong to the Tokugawa shogunate. Those who have less than 10,000 koku and are qualified to serve as generals are called flags. Those who are not qualified are called family members. The Tokugawa shogunate has about 5,000 flags and more than 17,000 family members. Counting
With these banners and family retainers, we can gather at least 80,000 elite soldiers."
Chongzhen asked with a smile: "Is it equivalent to establishing the Eight Banners of Manchuria as a slave?"
"Absolutely." Zheng Zhilong said, "But the national strength of Jiannu is far from being comparable to that of the Japanese state. In addition to the 80,000 banners directly under the shogunate, the Japanese state can recruit hundreds of thousands of ashigaru if necessary! It can even recruit the entire country.
Hundreds of daimyo will send troops to help in the battle, and by then our great soldiers will be trapped in a tight siege."
The troops are attacking far away, and they are far away from each other. Once they are trapped in a tight siege, they are basically dead.
However, Chongzhen had absolute confidence in the Ming army, and this was not blind confidence, but a self-confidence. Five hundred thousand Jian slaves equipped with so many firearms were defeated by the Ming army. What did a mere Japanese slave mean?
Even if the Ming army has no hope of victory after retreating ten thousand steps, self-preservation will not be a problem after all.
Because the Ming Dynasty had an absolutely superior navy, let alone the Japanese, even the most powerful Dutch navy in the world during this period would be defeated.
Zheng Zhilong had not participated in the Battle of Baliqiao, so he did not know enough about the Ming army.
In other words, the warriors of the Japanese country left a deep impression on Zheng Zhilong in his early years, which caused Zheng Zhilong to misjudge the combat effectiveness of the Japanese slaves and the Ming army, but Chongzhen would not misjudge.
At that moment, Chongzhen said: "Let's attack Osaka City and change the plan."
"I accept the decree." Zheng Zhilong had no choice but to modify the plan with a few staff members.
