Liu Ponu didn't dare to guarantee that his method was right, but judging from the current situation, there was some room for manipulation in doing so.

It's just that you need to consider the success rate of the shot, but no matter how you think about it, you have to make something first and then study it, right?

Now Liu Ponu's small courtyard has almost become a small workshop, although the equipment for various tests is not large, but the quantity is very complete, even a small iron-making blast furnace has it.

And with the support of such hardware conditions, the question raised by Liu Ponu is not a problem at all.

Everyone didn't even bother to eat lunch, and directly started a new round of work.

The first is to create a new bottom cap using abrasives, which is different from the previous one by adding a firing pin inside.

The bottom cap is prepared in two ways, copper and iron, anyway, it is a test now, it doesn't matter what material is used, which one is good in the end.

Others began to help with other things, polishing flint, finding the right paper.

It didn't take long for a new bottom hat to be made.

Of course, there was only one test to make one, and while they were working, everyone made twenty bullets without warheads in one go.

However, it turned out to be ......

"It shouldn't be, this copper is a little soft, and it's understandable that it can't make a spark, but why can't this iron spark?" Looking at the results of the experiment, Huang San was once again stunned.

Now he was really confused, and there was no way to do it.

Everyone knows how high Liu Ponu's expectations are for bullets, and they are enjoying the best treatment here, but nothing has come out for so long.

"Give up the flint road...... "Dismantle the bottom hats that did not ignite and study them carefully, Liu Ponu finally chose to give up.

It turns out that flint cannot be used as a primer.

And these twenty bullets used their real situation to tell Liu Ponu that this road would not work.

Although he had tried every way he could think of to assist him, he could no longer guarantee that every impact of the flint would produce sparks in the limited space.

Only three of the twenty bullets were successfully ignited, and neither copper nor iron could cause the firing pin inside the bottom cap to bounce back after impact.

That is to say, once the trigger is pulled, it is a one-time shot, and if you successfully hit the spark, it will be successful, and if you fail to hit the spark, it will naturally be GG, and no matter how you pull the trigger later, the bullet will not be able to be shot.

After the violent impact, some of the flint has already shown several cracks.

In other words, it's unreliable.

Similarly, this also means that before the real firing medicine is made, Liu Ponu's dream of fixed-loading bullets is basically bankrupt.

And listening to Liu Ponu's announcement of the failure of this line of thinking, Huang San and the others couldn't help but be disappointed.

I've worked hard for so long, but I've just done useless work?

Anyone else would find it unacceptable.

"Your Highness, please give me some more time, I will definitely find a way to solve this problem!" Huang San looked at Liu Ponu with a resolute face.

In order to study the principle of bullets, he even studied the composition of gunpowder seriously.

I don't dare to say much, at least Huang San's name should be included in the name of the Han gunpowder expert now, and not only that, he even learned the manufacture and improvement of some equipment, and many of the equipment used for testing were thought up and transformed by himself little by little.

Although it looks primitive, even so, the current Dahan is definitely a representative of high-tech talents.

And everything that Huang San and the others did, of course Liu Ponu saw it in his eyes.

Even if Liu Ponu still knows that there are some things they are doing useless work, but Liu Ponu still did not stop it, failure is the only way to success, no one can do it in one step, and can succeed without experiencing any setbacks.

"Research requires a spirit of not admitting defeat, which you have done very well, but research is not to drill the horns, every failure, not only to see the result of failure, but also to see why it will fail, but also to learn to draw inferences from one another, and try to avoid similar failures in future experiments."

"What is the spirit of not admitting defeat? That is, I know that once the bullet is a new weapon, it will inevitably replace the current war model, which can allow us to reduce countless casualties, I know that this general direction is in favor of the Han, and I know that this thing is the trend of the future, so I must find a way to study the bullet, which is called the spirit of not admitting defeat. ”

"Although the flint fire rate is very high in external experiments, and even as long as the contact area is large enough, the flint fire rate is almost 100%, but the bullet is only so big, and if we want to use the flint, we must first reduce it, which leads to the inevitable reduction of the contact area and the fire rate."

"Although the test just now was the result of hasty work, maybe after your efforts, the fire rate can be greatly increased, but so what?"

"The contact area between the firing pin and the flint is so large, and the factor of manual polishing must also be taken into account, plus the flint is processed too small and too thin, you must consider the risk of chipping, even if you can solve all the problems, can you finally guarantee that every bullet made in the future will be fired?"

"On the battlefield, if only half of the ten bullets can be fired, how much will it be delayed? Maybe it doesn't matter to us, it's just a matter of pulling out a bullet and replacing one, but the time wasted by a bullet is enough for the enemy cavalry to advance twenty or thirty paces, and a small mistake on our part will require the soldiers to fill the hole with their lives when they get to the front. ”

"Therefore, the idea of abandoning flint is not because he really can't use it, but because he has a huge flaw in this design, and since we have found a problem, then we must correct it as soon as possible." Liu Ponu enlightened Huang San and the others with a serious face.

For them, this is a very strange road, just saw a little hope, and then the hope was extinguished, and the heart was uncomfortable, that is also certain.

This is persuading Huang San and others, and it is also persuading himself.

While shouting to them not to worry, don't always think about eating a big fat man in one bite, on the other hand, I always fantasize about being in one step and eating into a big fat man in one go.

Liu Ponu also found that he seemed to be a little too anxious, in addition to the reasons just mentioned, another reason for Liu Ponu to give up using flint is that he can't guarantee that there will be no mistakes in the production process, maybe there is no problem with the design, but a little negligence in the production process may lead to the occurrence of old problems.

War is such a thing, what we want is stability, we can't always pin our hopes on probability, and it's better to use the current cold weapon directly.

After the comprehensive replacement of iron weapons, the combat effectiveness of the Han army has undoubtedly increased to a big step, and the strength of the current Han army can still crush all the surrounding enemies.

Therefore, the strength is not the biggest problem facing the Han Dynasty, the biggest problem facing the Han Dynasty at the moment is the sharp decline in population, and the people are unwilling to fight.

Liu Ponu couldn't help but start a new round of reflection.

The original intention of building guns was to use the least number of troops, fight the biggest battle, and exchange the least casualties for the greatest results.

In order to reduce the burden of war on the people, let one after another small casualties and big victories stimulate the people, improve their sense of national honor, and make them no longer have antipathy to war.

Of course, continuous wars are of course not feasible, and Liu Ponu's ultimate goal is still stable development, but when the war comes, everyone will not object, and everyone will support it.

In cold weapon warfare, advanced weapons also require short-term encounters, and there will be various uncontrollable factors in short-handed combat.

Hand-to-hand combat, even if it is a veteran who has fought for many years, does not dare to guarantee that he will be uninjured after a battle, and if he wants to ensure an advantage, in addition to improving his own strength, he also needs to ensure that there is no big disadvantage in terms of troops to the greatest extent.

In this way, the problem goes back to square one.

If you want to normalize winning more with less, you can do it now, but the number of troops is still out of range, and if you want to go further, you must make a qualitative jump in weapons.

So, guns are still essential.

Whether it's an arquebus or a flintlock pistol, both guns need to face the real problem of insufficient firepower.

Facing the infantry is naturally no big problem, as long as their tactical arrangements are reasonable and the allocation of troops is no problem, they can easily solve the infantry on the opposite side.

But when encountering cavalry, it can only be blind, within the range of fire, the cavalry can rush over in a maximum of ten seconds, even if the wheel tactics are used, it is difficult to ensure that all soldiers can fire two shots.

And the infantry with flintlock pistols meets the cavalry charging at high speed, as long as the opponent breaks through the range fire network, the rest is basically slaughtered.

If both sides are flintlock pistols, the scene of the line being shot will be repeated again.

But now......

It is so difficult for the big man to have his own plug-in to get a gun, even if he loses some guns on the battlefield, with the ability of those barbarians, I am afraid that he will not be able to control it.

Not to mention more, they can't solve the problem of iron-smelting technology, so isn't it also advanced if you go one step further?

As for the melee after being broken through by the cavalry, this problem is not at all for the Han army now.

To put it bluntly, the advantage of cavalry lies in speed, and cavalry fights with infantry, not that they can be killed by rushing into the opponent's formation.

Cavalry impact infantry, is the need to maintain a high-speed state to penetrate the infantry formation, and then reach a certain distance after turning back and then charge, the cavalry to the infantry is the greatest threat of the impact of the horse, the cavalry wielding a knife to slash what knowledge piggyback on the welfare.

This is also the real reason why the main force of the Xiongnu 80,000 surrounded Li Ling's 5,000 infantry, but failed to break through the infantry battle formation despite the loss of nearly 10,000 people.

The Han army has been superior to the Huns in terms of individual combat effectiveness from beginning to end, and the reason why Emperor Wu of the Han Dynasty fought so passively before was because of his poor mobility ability, and when he encountered a real tough battle, the kind of decisive battle face-to-face, the Huns were defeated once, and it has been like this since ancient times.

"The primer needs to continue to be studied, but the direction needs to be changed......"
