Second Artillery Bureau.
Tao Zengguang and Hu Yuancheng carried a long and narrow box and placed it on the stone table. Hu Yuancheng took out the key, opened the box, and stepped aside.
Zhu Yunwen stepped forward and looked at the long fire gun in the box, feeling very satisfied.
The firecrackers in front of us are no different from the primary rifles of later generations. They have long barrels, triggers, brackets, scopes, bolts, and butts.
There are four boxes placed at the four corners of the box.
Tao Zengguang took out a box and opened it, revealing neatly arranged gold and bronze bullets.
Zhu Yunwen took out a bullet. The bullet had a pointed tip and a round body. The middle and lower part was the cartridge case. The inside of the cartridge case was the powder chamber. At the bottom were two ring gaskets. The gaskets were slightly convex, but the convex position did not exceed the bottom edge of the cartridge case. the height of.
Tao Zengguang looked at the bullet, recalling the hardships of the research process, and said in a low voice: "Your Majesty, the lethality of this bullet exceeds that of ordinary lead bullets, but there are always problems with shooting accuracy. No matter how much we improve, Even if the best gunman controls it, there will be problems with its accuracy. Even if it is aimed at a hundred steps away, it will not be able to hit accurately."
Zhu Yunwen held the bullet and asked: "What is the success rate of this bullet?"
The corner of Hu Yuancheng's mouth moved: "Nearly 90%!"
Zhu Yunwen smiled and nodded slightly: "If it can be fired smoothly, this is the greatest victory. As for the accuracy issue, it does not lie in the bullet or the gunman, but in the barrel."
"barrel?"
Hu Yuancheng was stunned for a moment, looked at the barrel of the gun, and said seriously: "Your Majesty, there is absolutely no defect in this barrel. I personally supervised and inspected it. There is absolutely no problem with the quality."
Zhu Yunwen picked up the barrel of the gun and tapped it with his fingers: "I believe you when you say there are no flaws. It's just that this bullet is different from ordinary loose lead bullets. There are often more than ten loose lead bullets fired at one time. The killing surface is exchanged for accuracy, but this Bullets don’t work. It can only fire one at a time. If you want to ensure accuracy, you need to let it spin and fire!"
"Spinning?"
Tao Zengguang and Hu Yuancheng looked puzzled.
How can this bullet rotate and fire?
Zhu Yunwen looked at the inside of the barrel. It was dark inside and the edges were very smooth. This was the progress of the Ming Dynasty's casting technology. He was pleased and said: "Inside the barrel, a rifling needs to be milled out with a knife. Only by manufacturing Rifling can solve the problem of bullet accuracy."
"Rifling, what is it?"
Hu Yuancheng didn't understand.
Tao Zengguang was also a little confused.
Zhu Yunwen put down his spear, looked at the water tank on the side, walked over, reached out and flicked it quickly, and soon a vortex appeared. He picked up a small piece of wood and threw it in. The piece of wood swirled down the vortex.
"The rifling is like a vortex, which allows the bullet to spin out along the line of the vortex. You should also have thrown rocks into the water, but they all rotate forward. Your research path now is The Craftsman Academy already has some experience in how to mill out rifling. They have made many milling cutters that can carve inside iron tools. However, the barrel is long and narrow, so it is not easy to make rifling. "
[An app that has been running stably for many years, comparable to the old book-chasing tool, used by all old bookworms.
What represents the industrial capabilities of Ming Dynasty is the successful manufacture and use of bolts.
Although this thing is simple, the standard processing of threads is simply terrible. It not only requires high strength and high wear resistance of the milling cutter, but also requires very accurate ruler scale.
From the processing of feet and inches to the processing of minutes and centimeters, some links even need to be realized in millimeter units.
The growing industrial base of Ming Dynasty created conditions for rifling and other processing.
Hu Yuancheng and Tao Zengguang understood the drawings and what Zhu Yunwen wanted. However, the Second Artillery Bureau did not currently have such talents and really needed to find people from the Craftsman Academy to cooperate.
"Is there any progress in the production of large artillery shells?"
Zhu Yunwen asked.
Tao Zengguang quickly replied: "The manufacturing of a batch of ammunition has been completed. A new type of artillery is being developed. It is expected that it will take another three months to complete the preliminary test. "
"Three months?"
Zhu Yunwen thought for a while, but did not force the speed to be accelerated. Instead, he said: "Hurry up to develop the rifling and deliver it for testing. Once it is available, speed up the operation and deliver it to the scouts as soon as possible."
"I will receive the order."
Tao Zengguang, Hu Yuancheng and others agreed one after another.
"The preparation of gunpowder bombs cannot be stopped. Forty percent of the gunpowder warehouse in Jinling was first removed by the navy, and then 50% was taken away by the army. The gunpowder warehouse cannot be so empty and uneasy."
Zhu Yunwen said solemnly.
Tao Zengguang assured solemnly: "Your Majesty, the preparation of gunpowder shells has been accelerated. Most of the manpower of the entire Second Artillery Bureau has been allocated to the manufacture of gunpowder shells. Currently, it can produce 3,000 Tiger Crouching Cannon gunpowder and 1,000 Divine Machine Gun gunpowder per day. It won’t take long for the gunpowder warehouse to be replenished.”
"good."
Zhu Yunwen inspected it and met the craftsmen of the Second Artillery Bureau. After some encouragement, he returned to Wuying Hall.
The chamberlain announced: "Liang Ruoshui from the Security Bureau wants to see you."
Zhu Yunwen nodded slightly, and saw an ordinary-looking middle-aged man walking over. His appearance was unremarkable, and he was even a little honest, the kind that you wouldn't find in a crowd.
However, this person's appearance is just a disguise. He is a young man from the Security Bureau with extraordinary tricks. Liang Ruoshui, a member of the Hangzhou Security Bureau, has become an ordinary sergeant in the palace.
After Liang Ruoshui saluted, he looked at the chamberlain beside Zhu Yunwen.
Zhu Yunwen waved his hand, signaling the chamberlain to exit the hall, and then asked, "Did you find anything?"
Liang Ruoshui nodded slightly, took out a folded piece of paper from his arms, presented it to the desk and stepped back: "Do you want to take action?"
Zhu Yunwen opened the paper and his pupils moved slightly.
On the paper, it was clearly written:
Chief of Staff Wang Ning!
Zhu Yunwen's face was extremely gloomy and he looked at Liang Ruoshui: "How true is this information?"
Liang Ruoshui said seriously: "As of now, it's ten points."
Zhu Yunwen picked up the brush, scrawled the words on the paper, and then tore it into pieces bit by bit.
The chief of the key department refers to the officer who guards the keys.
Wang Ning, the chief of the key department, is not looking at the keys to the outer city and city gates of the capital, but the keys to the palace gates!
Being able to take on the important task of guarding the palace gate is certainly not an ordinary person.
And this Wang Ning's identity is very unusual, because he is the son-in-law of Taizu and the husband of Princess Huaiqing. His status is the same as Mei Yin and Li Jian, they are both consorts!
According to seniority, Zhu Yunwen had to call Wang Ning uncle when he met him.
This person has always been very honest over the years. He has never seen any problems or even made a mistake. He is so diligent that he has no sense of existence.
But just when the storm was about to come, Wang Ning got involved.
Liang Ruoshui's information was unmistakable. Since he found out that Wang Ning was involved, it must be true.
"So, some people want to come to my home as guests."
Zhu Yunwen said softly.
Liang Ruoshui nodded heavily.
People in the dark are stepping up their activities, their
The focus of the activity is not just on the wealthy and wealthy households outside the city and at the city gate. In Liang Ruoshui's view, those people are just responsible for attracting the attention of the Security Bureau and distracting the Security Bureau's manpower. They probably don't know the real purpose. Something got involved.
Their real goal is the palace!
The key chief controls the palace key. If the key is leaked, it means that the opponent can enter the palace relatively easily!
"We have been in Jinling City since ancient times, keeping an eye on everyone in the palace, especially regarding access control, badge issuance, keys, and purchasers. In addition, let Xu Sanqian, Mei Zhiyun, and Lin Zhaoxue keep an eye on the generals in the military camp. Watch the military camp, and if any general mobilizes his sergeants without permission and leaves the camp without orders, he will be killed."
Zhu Yunwen threw the scraps of paper into a good wooden box. There were already many scraps of paper in it.
Liang Ruoshui solemnly agreed.
Zhu Yunwen waved Liang Ruoshui away, knocked on the wooden box, then sat down and murmured: "If you want to come, then come. I also want to see who you are."
Just as Zhu Yunwen was reviewing the memorial, the queen's personal maid Yinxiu hurried over. The chambermaid Shuangxi learned the news and eagerly reported: "Your Majesty, Princess Baoqing accidentally fell into the water."
"How could this happen? What happens now?"
Zhu Yunwen was taken aback and quickly stood up and walked out.
Princess Baoqing is a very special person in the palace. She is the youngest daughter of Taizu and the youngest aunt of Zhu Yunwen. She is only fourteen years old this year!
In the palace, the queen mother, empress, and concubines all doted on Princess Baoqing. Zhu Wenkui also had a very good relationship with Princess Baoqing. Zhu Yunwen was busy with official duties all year round. Although he loved Princess Baoqing, he still left it to the queen to take care of her most of the time.
Who would have thought that he would fall into the water so accidentally!
Yinxiu trotted to keep up with Zhu Yunwen's footsteps and said from the side: "Princess Baoqing is not seriously ill, she was just frightened. The queen has sent for the imperial doctor."
Zhu Yunwen breathed a sigh of relief. As long as the person was fine, that would be fine. If the person had an accident, he would have no way to explain it to his grandfather and father.
"It is said that Tang Buping and Chu Yun went to the palace to investigate and find out why Princess Baoqing fell into the water!"
Zhu Yunwen gritted his teeth.
Princess Baoqing is just a child. Whether someone attacked her or it was just an accident must be investigated clearly.
Kunning Palace.
Princess Baoqing was lying on the bed, and the queen, queen mother, concubine Shu and others came.
Zhu Yunwen didn't care to salute the Queen Mother, and took two steps at a time to look at Princess Baoqing in front of the bed. Princess Baoqing burst into tears and shouted "Your Majesty". Seeing Zhu Yunwen comforting her, she cried even louder.
