Zhu Cijiong looked carefully at the experimental field for a while, but still didn't understand how the grenades and artillery in it were used to experiment with new gunpowder.

However, he didn't ask anything, but raised his hand to signal for the accompanying testers to start the test.

Anyway, just see what they do next, if you want people to explain, you may not understand the explanation for a long time.

The experimenters got the emperor's will and hurriedly ran to the wooden table where the grenades were placed.

Strangely, instead of getting the grenades on the wooden table, they lowered their heads and pulled out a bunch of shields from under the wooden table!

Good guy, this experiment is really dangerous, and you have to use a shield to block it!

Zhu Cijiong still didn't say anything, he naturally took a shield and held it in front of him like the person next to him.

Only then did he realize that this was not an ordinary shield, and there was an observation hole inlaid with thick glass in front of it!

Seeing that the emperor was ready, one of the experimenters stepped forward to pick up a grenade, holding a thunder in one hand and a shield in the other, biting off the safety bolt on the grenade, and then throwing it into the wooden pile in front of the low wall.

With a loud "boom", Zhu Cijiong felt that the entire ground seemed to shake, and then there was a rain of sawdust in front of him!

Damn, it's so powerful.

When the sawdust fell, Zhu Cijiong put down his shield and looked into the pile of planks and wooden pillars, where a hole of several meters in a radius had been blown out, and both the planks and wooden pillars in the middle were gone, and the planks and wooden pillars around them were also in tatters, a mess!

This is simply a fight with the grenades of later generations, and it seems that the power of this high-explosive gunpowder is equivalent to that of later generations!

Zhu Cijiong nodded excitedly, then pointed to the artillery next to him and said, "Go on, go on, you go on." “

When the experimenters heard this, they immediately dropped their shields, quickly opened the back cover of the naval gun, stuffed in a sub-tube that had been prepared a long time ago, and then closed the back cover.

After doing all this, they looked to Zhu Cijiong that this meant that they were ready.

Seeing this, Zhu Cijiong nodded without hesitation and signaled that he could fire.

I saw an experimenter pull it on the flintlock behind the naval gun, and with a "boom", a shell immediately flew out and hit the high wall in front of it, and the fragments were splashed everywhere, and a pit the size of a basin was suddenly smashed into the high wall, and the deformed shell immediately fell to the ground.

This power is similar to that of the original artillery, except that the flint is not equipped with flint, and there is no spark behind the cannon when it is fired, and it is obvious that the shell is fired by hitting the detonator inside through something in the form of a firing pin.

After reading these two experiments, Zhu Cijiong praised him with great satisfaction, and then asked Bi Maokang to take him to the office, as if he wanted to say something to Bi Maokang.

It can be seen from the effect of the test that both high-explosive gunpowder and initiating gunpowder have been successful, and the effect is no different from the gunpowder of later generations, but their usage is a little wrong, or too one-sided, and it is exactly what Zhu Cijiong wants to say to Bi Maokang.

Bi Maokang led him to a separate study, took out the pen, ink, paper, and inkstone, and stood there to sharpen the ink himself.

Zhu Cijiong didn't care about him, just sat at the desk and thought about it carefully.

What should we do first?

Rifles, no, he is familiar with rifles with magazines, just that magazine can not be done in a short time, not to mention that bullets have to be made, and the structure of the gun body must also be overhauled, with the current industrial base of the Ming Dynasty, there is no more than half a year, and the samples cannot be made.

Howitzers, it doesn't seem to work, the simplest howitzers in later generations will not be built in a few months under the existing industrial base, at least a year, and it will obviously not be able to catch up.

It seems that the only way to improve the existing weapons is to use the existing weapons as a blueprint to make them play the functions of high-explosive gunpowder and detonating gunpowder at the same time, and this speed should be the fastest.

In fact, the grenade he just saw could play the function of high-explosive gunpowder and detonating gunpowder at the same time, but this thing was too limited and could only be thrown out at close range, and not all battles could be effective, especially in naval battles, this thing was useless at all.

The only way to play the role of deciding the outcome of the battle is artillery, and if the shells fired can be loaded with high explosives like the shells of later generations, and can detonate on their own, then the destructive power will be amazing.

He thought about it for a while, and then came up with a more suitable plan, that is, to modify the sub-tube of the ship's gun.

Now the naval guns of the Ming Empire Navy are all sub-mother howitzers, and the sub-tube can be pre-loaded with ammunition, and when the cannon is fired, you only need to stuff the sub-tube into the mother tube.

This sub-tube is a bit similar to the shells of later generations, except that the warheads fired out, that is, the structure of the shells is different from the warheads of later generations.

In fact, this problem is not difficult to solve, just change the shape of the shell, turn it into a cone, fill it with an appropriate amount of high-explosive gunpowder, and then use the detonating gunpowder to make a fuse out.

To put it bluntly, it is to make a simple warhead out.

The simple warhead is not difficult, Zhu Cijiong thought about it and drew it.

He first drew a diagram of the outline of the sub-tube that is now used, and then said to Bi Maokang: "Meng Hou, this is the sub-tube of the ship-based sub-tube howitzer, you know, right?" “

This Bi Maokang naturally knew, and he nodded hurriedly and said, "Back to the emperor, Weichen knows." “

Zhu Cijiong nodded, and then drew a sub-tube, but this time this sub-tube is a bit special, the second half is a bit like a cannonball shell, a bit of a fire cap, there is a powder room, and the first half is directly a conical warhead.

After finishing the painting, he said to Bi Maokang: "Meng Hou, look, this is an improved subtube, here is the detonating gunpowder, here is the high-explosive gunpowder, here is the cannonball, do you understand?" “

Bi Maokang looked at it carefully, and then nodded: "Weichen understands." “

In fact, they have already taken into account this ignition cap and the powder room, but the structure is slightly different, and he can naturally understand it at a glance, as for the cannonball, it just changed from round to pointed, and there is nothing difficult to understand.

Zhu Cijiong nodded, and then drew a separate diagram of the internal structure of the cannonball.

After finishing the painting, he said to Bi Maokang: "Meng Hou, you see, I want you to make cannonballs into flowering shells, which are filled with high-explosive gunpowder here, and detonated with detonating gunpowder here, no longer detonated with flint, but directly detonated with detonating gunpowder, do you understand?" “

This is actually similar to the blossom bomb, Bi Maokang naturally understood it at a glance, and when he heard this, he immediately nodded and said, "Weichen understands." “

Zhu Cijiong nodded with satisfaction, and then asked, "How long can this kind of sub-pipe be made?" “

Bi Maokang thought for a while, and then replied: "Back to the emperor, if it is just a sample, add a month of test time." “

Zhu Cijiong asked again: "What about mass production?" “

Bi Maokang thought about it again, and then replied: "Back to the emperor, if you want to mass produce, you have to add another half a month." “

When Zhu Cijiong heard this, he immediately clapped his head and said: "Okay, start development immediately and achieve mass production as soon as possible." “
