Chapter 806: fuse

The spring breeze blows the peach blossom outside the imperial study room, bringing a faint fragrance.
After sending away Princess Pingyang, Xiao Ming became lazy. One month has passed since his return from Shanhaiguan, and Qingzhou is already full of spring.
Looking at the peach trees blooming with crimson flowers in the sunset, Xiao Ming was ready to accept a day's government affairs and prepare to go back.
This is Qian Dafu running all the way, "The emperor, Lu Tong and Chen Qi, please see you?"
"They?" Xiao Ming showed a look of interest, he said: "Let them in, there must be something new for the two of them to come together."
"Yes, the emperor." Qian Dafu also has a smile on his face. In fact, he likes Chen Qi more than Pang Yukun, because they bring good news every time.
Qian Dafu replied, and soon Chen Qi and Lu Tong entered the Imperial Study Room.
The two looked excited, and after saluting, said: "My lord, the fuse is complete."
"I said that you must have good news." Xiao Ming said to Qian Dafu, Qian Dafu also smiling pretty.
Chen Qi and Lu Tong looked at each other with a smile, and Chen Qi took out the small stick at this time, "The emperor, this is the triggered mechanical fuze."
Lu Tong explained: "This time the fuse was successful thanks to the flash hider. After thinking about it, Xiaguan and Chen Qi found that the principle of the fuze is similar to that of the flash hider, but it only requires an external force to hit the thunderbolt. So we A firing pin is installed outside the letter tube that has hit the thunderbolt. As long as an external force hits the firing pin cap, the firing pin will hit the thunderbolt, and the thunderbolt will then ignite the explosive powder in the fuse, thereby igniting the shell."
Taking the fuse carefully, Xiao Ming looked it over and was very satisfied.
The fuze Chen Qi gave him was a thin metal cylinder, and on the outside of the cylinder was a metal cap with a firing pin.
Open the metal cap and you will see a slender spring inside. This is to ensure that the fuze will not explode due to operating errors.
In the middle of the spring is an ignition device similar to a flash cap. When the firing pin cap is hit, the firing pin will ignite the thunderbolt downwards, and the fuse will cause the shell to explode.
In the past, the difficulty of fuzes was the spring and thunderbolt. Now Qingzhou Industry has been able to produce these two, and the fuze manufacturing has been smoothly completed.
However, compared with modern fuzes, the trigger fuze has a relatively high error rate. If the impact point is not correct, it is likely to cause a dud bomb.
But even so, the birth of the fuze is trans-epoch, because the fuze can be used on landmines in addition to shells.
Thinking of this, Xiao Ming suddenly had a very evil idea in his mind. For the trigger fuze, the shells formed in the circular hollow bullets are no different from landmines.
Only one needs to be launched to hit, and the other needs to be stepped on. The real difference is only the sensitivity, and the force of the spring needs to be reduced.
He said: "You now immediately make a batch of hollow shells with fuzes for the front line of Jinzhou City. I will order Lu Fei to attack the city one month later."
Chen Qi and Lu Tong looked at each other, the evil look on Xiao Ming's face made the two of them tremble, and the two of them answered yes.
After sending them away, Xiao Ming showed a strange smile on his face. In fact, landmines have long been recorded in history books.
The earliest documents need to be traced to 1130, when the Song Dynasty Jin Army attacked Shaanzhou, when the Song Army used gunpowder cannons buried on the ground, that is, iron-clad mines, causing heavy casualties to the Jin Army.
In the early years of the Ming Dynasty, real landmines using mechanical ignition devices appeared in Daming. According to the first collection of "Fire Dragon Scripture" written by Jiao Yu in 1413: "Frying and concocting are made of pig iron, empty stomach, put medicine and pestle into a small bamboo tube, thread the fire inside, and use a long thread to pass through the fire trough. Dozens of them were buried in the pit, the medicine trough was connected to steel wheels, and the soil was covered, so that the thief would not know it.
This type of landmine recorded in the classics has the characteristics of contemporary pressure-fired landmines, but this type of landmine uses steel wheels and flint to friction and ignite, like the principle of a lighter, and its reliability is still a bit poor.
In Europe, landmines also began to appear in the defense of fortresses in the 15th century. It was only after the mid-19th century that landmines were used on a large scale with the emergence of various high explosives and detonation techniques.
Now the fuzes manufactured by Chen Qi and Lu Tong are basically close to those of the 19th century. Using such fuzes to make landmines is much more reliable.
In the process of attacking Pingzhou, the army of Great Yu State has been constrained by the cavalry. This time it may be possible to experiment with landmines.
Thinking of this, Xiao Ming became more and more looking forward to it.
I imagined for a while alone, Xiao Ming returned to his bedroom before the sky was completely dark.
At this time, Fei Yue'er was following Xiao Yi, who was learning to walk step by step. Xiao Yi is now one year and three months old, and it is the time to learn to walk.
Seeing Xiao Ming's arrival, Xiao Yi's small face was full of smiles, and he leaped towards Xiao Ming with a crisp laugh.
Cui Xueer stood beside Lulu Aster, and smiled when she saw it.
"The emperor went to Shanhaiguan here, and after coming back, Xiao Yi liked to stick to the emperor more." Aster smiled.
Luluo said, "No, I don't care about us now."
Cui Xueer is now also familiar with the environment of the palace. She plays mahjong with three people every day. This feeling is also close to sisters, without the gloomy feelings when she first entered the house.
She glanced at Xiao Ming, "It's just that the emperor is busy with government affairs and rarely can accompany Yi'er. It would be nice to have a prince of the same age with him."
As soon as her words fell, Luluo and Zixuan both looked at Xiao Ming, each with bold and fiery eyes.
Both of them and Xiao Ming were married, so they were naturally not as shy as a girl, and they took it for granted.
Fei Yueer smiled upon hearing the words: "You are not ashamed of each one, don't frighten the emperor."
Xiao Ming was a little helpless~EbookFREE.me~ Now he finally realized the difference between a girl and a young woman, but it was really painful and happy.
After laughing with the four for a while, Xiao Ming noticed a beautiful jade pendant hanging on Xiao Yi's neck, and he asked, "Where did this come from? Why have I never seen it before."
Fei Yue'er said: "Today, Princess Yong visited the queen mother in the palace, and later visited her concubine, and gave this jade pendant to Yi'er when she left."
"Princess Yong." Xiao Ming raised her eyebrows, "Princess Yong always goes to the Three Treasures Palace, so she must have something to ask for."
"The great victory of Pingzhou, the emperor defeated the barbarians, and his power in Dayu is no different at the moment. This king Yong must be unsure of his heart."
Xiao Ming nodded lightly. Concubine Yong entered the palace at this time. Everyone with a discerning eye knew it was not accidental. Since Concubine Yong went to the Queen Mother first, it is estimated that the answer lies with her.
When the two were talking, Cui Xue'er's eyes flickered and she lowered her head.
