Nearly half a month has passed since the test explosion of the earth-shattering thunder.

Xia Hongsheng did not rush to report the situation of gunpowder to the emperor, but continued to use gunpowder to try to make other weapons. After all, gunpowder is only a raw material, and all kinds of equipment that uses gunpowder are weapons that can make gunpowder diversified and extensive.

Xia Hongsheng made a sky-shattering thunder, which can be carried with him and can attack enemies at medium and close range.

In the course of five days, another explosive package was made. The principle is the same, however, because the power of black powder is limited, and the sealing conditions of the explosive package are also limited, so at least 20 catties of black powder need to be pressed into the explosive package to play an effective role. Twenty pounds is usually not heavy, but a soldier who fights can never carry anything more than twenty pounds on his body. Fortunately, the trebuchet can get the explosives pack to do its job. The power of the explosive pack is proportional to the weight of the gunpowder inside, and it can be used to ignite the fuse and throw it through a trebuchet for long-range attacks or to blast walls.

Because the weight of the explosive package is too large, the seal is not good, and the power is weakened, so it is only suitable for blind long-distance throwing. So Xia Hongsheng made another kind of bomb. It is in the shape of a cylinder, with a thick cylindrical metal container filled with explosives in the middle, and a circle of thinner cylindrical metal containers, also filled with explosives, and their leads are twisted together. The advantage of this shape is that if you want to increase the power, you only need to add more cylindrical bombs. Because it is sealed in a metal container, it requires less explosives than a powder pack, but it is more powerful. In addition, it can be split up and used as individual bombs.

In addition, combined with today's combat methods, the two armies face each other, their respective positions, and then impact each other, and the cavalry is the mainstay, so Xia Hongsheng originally thought that if he could make mines, then in the battle of the military formation, when the enemy cavalry rushed over, he had to step on the mine array first, and when the mine array passed, it was estimated that the cavalry was killed, overturned, and frightened, and basically there was no combat effectiveness.

There is no way, in the face of absolute force, sometimes all other efforts are in vain. It's like the 2,000-strong Eight-Nation Coalition against the 190,000 Qing soldiers, it's like a bow and arrow against artillery. Everything Xia Hongsheng did was to prevent the tragedy from recurring in the future.

It's a pity that because there is no effective ignition device, Xia Hongsheng's mine dream can only be put on hold for the time being.

If the mines are buried in the ground, they can't be lit one by one by man! Even if you string the leads of a mine together, you still need someone to light it, and it is too inconvenient to use.

The effect that Xia Hongsheng wanted was that when the enemy stepped on it, he could trigger the ignition device, and the ignition device would detonate the mine.

I remember that the mechanical automatic ignition device seems to have been widely used in the Ming Dynasty, that is, before the Ming Dynasty, there was already a technology to make this mechanical automatic ignition device. In addition, there is also the flint technique, which is also a difficult problem that must be overcome.

The automatic ignition device allows the fuse to be ignited without the need for a human person, while the flintlock device is related to the absence of an open flame, as well as ...... Flintlock pistol!

The principle of flint is not very difficult to understand, and after a lot of experiments, it will definitely be able to be made in the future. But with the automatic ignition device, Xia Hongsheng was helpless.

The success of gunpowder is indeed an epoch-making significance.

muskets, grenades, grenades, explosives, and even cannons...... Xia Hongsheng couldn't wait to be able to make all these things at once.

It's a pity that Xia Hongsheng is not Baidu, even if it is Baidu, there are times when "according to relevant laws, regulations and policies, some search results are not displayed", so Xia Hongsheng can only make these simple firearms first, and then hope that there can be smart craftsmen, on the basis of these firearms, from a relatively high starting point, to explore and think, to gradually invent those more advanced things.

Five days is a very short time, so Xia Hongsheng is only enough to make two or three of each thing, one is used for experiments, and the rest is kept for Li Lao Er to see the effect and power. There are quite a few earth-shaking thunders, there are two boxes, dozens of them.

Prepare everything, seeing that the Chinese New Year is coming, it is time to give Li Lao Er a dowry.

During the day, the gate of the palace, if there is no accident, it has always been open to Xia Hongsheng. This is Xia Hongsheng's privilege, and it is also a means for the emperor to show his trust in Xia Hongsheng and win Xia Hongsheng's loyalty.

"It's cold today, and it's the middle of the year, what are you doing looking for me?" Li Shimin knew that Xia Hongsheng would not take the initiative to come to him if he was fine, so he said-Actually, who would? Who would come to the Emperor when they have nothing to do? Even if it's his family, it's not the ones who are deeply loved, but I'm afraid it won't. This is the loneliness of the emperor.

Xia Hongsheng looked at Li Shimin, who was sitting on the coal stove and reading a book on the coal stove, and suddenly felt some sympathy for him in his heart.

"It's freezing this day, Weichen came to see if it was warm here, and if there was anything that was easy to induce illness, I didn't notice." Xia Hongsheng said to Li Shimin: "For example, right now, there are so many coal stoves in the hall, and it is warm to get warm, but it is easy to get the flu...... Uh, wind chill. Therefore, you have to pay attention to air circulation and open the windows for ventilation! In fact, just sitting on the coal stove, it is better to go out and move, it is warm, and it strengthens the body, and it can also make the mood better. It's gloomy weather, and it's easy to be in a bad mood. ”

"It's light, it's freezing and snowy, what kind of activities are I going to do?" Li Shimin thought that he was also a widow who read books, and when someone was talking, he simply put down the book and said: "I have extended the time for morning exercise, this broad daylight, is it possible for me to run outside and box?" ”

"This and this...... Your Majesty can go to the harem, there are no outsiders there who can see it. Your Majesty can have snowball fights with all the mothers, or the princes and princesses, build snowmen, and make some trouble, so as to ensure that your mood is suddenly brightened. Xia Hongsheng said to Li Shimin.

Li Shimin stared at Xia Hongsheng, shook his head a little angrily, and said, "You kid, your eyes are very poisonous. Tell me, how do you see that I'm upset? ”

It's almost like writing the word "depressed" directly on your face, big brother!

Of course, Xia Hongsheng couldn't say that, so he said: "When Weichen came in, he saw that His Majesty was also absent-minded when he read a book, and his eyebrows were tightly locked, so he knew. Why is Your Majesty so upset, it is inconvenient for Wei Chen to ask. However, Weichen can have a way to make His Majesty happy. ”

"Oh? Let's talk about it. Li Shimin looked at Xia Hongsheng with interest.

"There are two ways to do this." Xia Hongsheng said to Li Shimin: "One is serious, and the other is playing." Which will Your Majesty listen to first? ”

Li Shimin leaned back: "Naturally, the right thing comes first." ”

"Okay." Xia Hongsheng nodded: "Then Weichen reports to Your Majesty, and the dowry that Your Majesty wants, Weichen has prepared." Today, I just want to ask Your Majesty to go and see if you are satisfied. It's not that Weichen made a time to drive His Majesty, but this thing really can't be brought into the palace. ”

"Oh!" Li Shimin's eyes froze, and he suddenly straightened his back and sat up straight. (To be continued.) )
