Huang Fu's return made Zhu Zhanji not worry too much about the affairs of the military department.

Huang Fu's abilities are trustworthy, and his loyalty is even more trustworthy.

With such an old minister staring at the Ministry of War, Zhu Zhanji's main focus during this period of time was on scientific research.

Recently, the chemical research institute of Xiamaqiao Farm has become the most lively place, although the train of the mechanical research institute is very attractive, but the first official test overturned, so that the researchers led by Ma Zhicai have become low-key.

For them, there was such a big mistake, but Zhu Zhanji did not scold them, it is better to scold them, so that they can feel at ease.

Since the train turned and rolled over because the connection between the wheels and the track was not tight, Zhu Zhanji provided another direction for improvement. In strict accordance with Zhu Zhanji's instructions, they began to transform the load-bearing part and wheel casting.

However, it is easy to cast a wheel with a diameter of twenty centimeters, but it is not so simple to cast a wheel with a diameter of more than fifty centimeters.

What's more, Zhu Zhanji also asked them to expand the inner wrapping and increase the wrapping power of the outer edge. The design, casting, and machining of such wheels all need to be improved a little bit.

Before they were able to make a difference, they are now very low-key.

But the Institute of Chemistry is different, since Blue Smoke took over the place, something new has been invented almost every day.

A variety of dyes have a function that directly exceeds the effect of Daming's existing dyes several times.

All kinds of explosives in different proportions, but very powerful, shook everyone's hearts again and again.

What convinced them the most was that it only took less than half a month for Blue Smoke to use the existing materials to make soda ash and pure acid, and the emergence of these two materials made them chemical researchers change their views on chemistry as a whole.

Because blue smoke gives a variety of uses for these raw materials, and these uses include almost all aspects of life.

When Blue Smoke used hundreds of catties of soda ash to make glass, pulled it to Ma's workshop to make glass, and then used these soda ash to make colorless glass, Ma Zhide, an expert who has been obsessed with the glass industry all his life, immediately regarded Blue Smoke as a god.

The colorless glass made of this soda ash is almost purer than the highest-grade glass produced by the Ma family, and there is no trace of impurities.

This can greatly improve the function of telescopes and microscopes, so that Majia's products are not competitive at all.

These new technologies have all been patented in the name of Lanyan Xiamaqiao Research Institute, with a patent term of 20 years.

In the past 20 years, the beneficiary of the patent is the Ming royal family, but as the inventor of the patent, Blue Smoke enjoys a 5% dividend.

Not counting these things, just those dyes of cloth and silk can make Lan Yan directly become the richest woman in the Ming Dynasty.

Because now it's not him who is working hard to promote, but tens of thousands of internal prisoners all over the world helping her promote. The invention of new technologies will not slowly expand its impact, but will directly radiate to the whole country.

If at the beginning, the Zhang family and Sun Xian still had a trace of suspicion about Lan Yan, but now, they really regard Lan Yan as the reincarnation of Dou Mu Niangniang, otherwise, how would she understand these strange things.

If the impact of these inventions is not surprising, then when she invented the battery that could store lightning, at least the people in the chemical research institute regarded her as a god.

Zhu Zhanji doesn't know much about the production of batteries, but the application of batteries is too extensive. Not to mention anything else, in the future, when the army is dispatched at night, a small team with a battery flashlight will not be afraid of not being able to see it at night.

Of course, batteries alone are not enough, and the manufacture of electric lamps can be said to be the most positive in Blue Smoke, but the progress is the slowest.

This is mainly because Lan Yan only has theoretical knowledge, and in other aspects, it can be made only by following the ratio of molecules, but the carbonization of bamboo silk requires her to keep experimenting.

The insulated bamboo wire is carbonized into a heat-resistant and conductive filament, which is by no means simple to make.

Just as she knows very well that growing mold with rotten melons can provide a large amount of penicillin bacteria, and with corn solution, you can prepare the culture medium.

But if you want to refine penicillin, even if the fleet that went to Dongzhou now brings back corn, it is impossible to refine penicillin without a year or two.

Not to mention penicillin, even the purification of sulfonamides, blue smoke can not do anything.

Sulfonamide was first discovered as a dye with a lot of color, but this dye is not uncommon, including her ability to configure.

But Parapro is a dye and sulfonamide is just one of the ingredients. It is not so easy to purify sulfonamides from this stain, and it is even more difficult than directly extracting penicillin.

Therefore, Blue Smoke simply gave up the research on sulfonamides and put the main goal on the research and development of penicillin.

But these works can only be promoted temporarily, and the people of the Institute of Chemistry now regard Blue Smoke as gods, although they don't understand why Blue Smoke wants to make so many melons and put them in the pool to let them rot, but they also start unswervingly.

Now it is not so easy to make a sterile laboratory, it can only be relatively clean, because other aspects are easy to do, but air purification is not at all possible with current technical means.

For example, the penicillin extraction tank is a pool built with cement, and then a large tile is pasted on the cement surface, although it cannot be said to be completely qualified, but it can basically achieve the effect of the test.

What Zhu Zhanji wanted to get the most was the telegraph, but when it came to radio, he and Lan Yan were both laymen.

He only knew the history of radio, the Morse code, and the principle of telegraphy, but he did not understand how telegraph used static electricity to transmit signals.

Now that the battery was invented, he gave this task to the Maoshan Taoist priest Keats, and asked Keats to learn the alphabet first.

Keats was also a strange man in this era, and when he was a child, he became a Taoist priest because of his poor family. However, he is not the kind of Taoist priest with regular plates, but a wild Taoist priest.

On the rivers and lakes, he learned the kung fu of pretending to be a ghost by studying magnets, and thus mixed into Maoshan Mountain.

In Maoshan, after being able to read many Taoist scriptures, he learned to use magnetic force to rub electricity from books such as "Huainanzi" and "Spring and Autumn Wei".

This set of tricks in this era, not to mention ordinary people, most of the powerful people have also been fooled.

When Zhu Zhanji recruited heroes from all over the world, Keats volunteered to come to the door.

Although Zhu Zhanji saw through his tricks, he did not expose them, but because of his research on electricity, he supported him.

When the generator was studied, Keats knew that his trick had not deceived Zhu Zhanji. He was fascinated by the research of the Electric Power Research Institute and is now an electric power expert in Daming.

In terms of electrical applications, he is definitely inferior to Madi, because Madi's whimsy, including hands-on ability, is not comparable to him.

But in the study of the principle of electricity, he is definitely an expert now.

The transmission of the telegram is to replace the 26 letters with dots and horizontal bars, long pressing the button is a horizontal bar, and pressing a short time is a point.

Each letter is annotated with four symbols, and the letters can be identified by receiving dots and horizontal bars.

Then determine one by one according to the symbols, and link them to form pinyin, so that a message can be formed.

At this time, he was glad that he had figured out the pinyin alphabet, otherwise, just decomposing the Chinese characters and trying to get a set of roots out of it would be a very difficult task, and the error rate would be higher.

Keats' task was how to use the transmission of electric currents and interruptions to transmit signals.

Zhu Zhanji only remembers that the telegraph machine at the beginning was to distinguish the letters by transmitting signals and punching holes in the paper.

But technically, he couldn't help at all.

After telling Keats the principle, Zhu Zhanji could only wait for him to study it thoroughly, and then he could use the line to test the telegraph.

As for radio transmission, that is simply unthinkable.

And most of Zhu Zhanji's energy is put into men's favorite toys, real gun manufacturing.

Whether it's a pistol or a spear, it's not that complicated to make.

In later generations, many technical experts could imitate June Fourth with a lathe, and it was not much different from a real gun.

The quality of the gun mainly plays on the process and material, and the big deal is that the quality is a little worse.

In contrast, bullets are really difficult to make, because the processing technology and chemical raw materials, even if they are placed in front of you, you can't imitate them.

It's like mercury thunderate for priming, you don't know chemistry, you don't know what it is. There is also the gunpowder in the bullet, which is not made by people who do not know chemistry.

However, now that she has blue smoke, she can solve these problems, and Zhu Zhanji will also have to solve the processing technology.

No matter what kind of firearm, it is mainly composed of three parts: the barrel, the firing linkage structure, and the grip.

In terms of processing technology, the design and frame precision of the triggering linkage structure are very important.

But in terms of material, the wear resistance of the barrel is the most important.

In contrast, the processing of the grip is much simpler.

The invention of the steam engine has actually solved the difficulty of processing the barrel.

It turns out that the lathe is driven by a water wheel, and there are often problems such as insufficient power. However, the kinetic energy conversion efficiency of the steam engine is much higher, which makes it possible to process the barrel made of pure steel at one time.

Moreover, now because of the research and development of lathe cutters, the invention of manganese steel, in the production of drill bits, cutting tools, have made new breakthroughs.

That is, even the rifling inside the barrel is not a problem to process.

This process is also very simple, it only needs to fix the milling cutter, and then rotate it as the lathe advances the barrel.

However, no matter how simple it is, it is necessary to improve the corresponding equipment so that it can be mass-produced for accessories.

Zhu Zhanji never thought that he could make an automatic rifle that could automatically unload the cartridge case at one time, but now the production of copper is still insufficient, and the cartridge case has to be recycled, and the automatic rifle is even more resource-intensive.

At a time when the world did not yet have muskets, a Mauser 1898 could be invincible in the world.

The linkage mechanism inside the gun is ignorant to the layman, but for Zhu Zhanji, it is not difficult at all.

In his previous life, he was very familiar with guns from all over the world, and he could assemble a gun with his eyes closed, so he was very familiar with these accessories.

Striking irons, triggers, linkages, springs, the inside of a gun, these are the main components.

What he has to do now is to make a gun by hand, then adjust the size of each part, determine the model of the part, and then improve the processing mold of the lathe according to these models of parts.

But now there is a problem, and that is that he is far more familiar with the pistol than the long gun.

He is now very sure that he can make himself a Boleta 92, which is also his favorite pistol in his previous life.

As for the long gun, he played the most with the SAR-21 fully automatic rifle produced by Singapore New Century, the kind of gun, with the current technology, don't think about it.

In this way, the complex cannot be done, the simple one is not familiar with, and the finalization of various accessories still needs to be studied for a period of time.

Every morning to deal with official business, in the afternoon, Zhu Zhanji is absolutely in the Xiamaqiao Farm, fiddling with his toys.

Ma Di began to act as his good student again during this time, and when he saw Zhu Zhanji scribbling and changing the drawings, it became 100,000 whys.

If he didn't really like him, Zhu Zhanji would be so annoyed that he couldn't wait to kick him out.

The spear has not yet been seen, and Zhu Zhanji has already completed a boletta first.

In terms of craftsmanship, this gun is definitely not comparable to the craftsmanship of later generations, and in terms of material, it is impossible to have the wear-resistance of later generations. But this gun, which was jointly created by the best craftsmen of the Ming Dynasty, definitely has the level of the early twentieth century.

Zhu Zhanji only let two pistols be made, and then destroyed all the accessories.

He made this pistol to satisfy his hobby of playing with guns, and he didn't want to spread it now. He won't be widespread for at least a few decades.

Because the spear is easy to guard, this pistol is not easy to guard, if it is made, and someone uses this pistol to assassinate him, he will have gone too far.

The other accessories of the spear were easy to make samples, but the linkage mechanism was changed again and again, and it took Zhu Zhanji nearly a month to solve the problem, and it still did not completely solve the problem.

Moreover, the mercury thunder acid promised by Blue Smoke has still not been produced.

Mercury thunderate is the earliest used initiating agent and has a high sensitivity to flame, acupuncture and impact. For more than 100 years since its invention, it has been an important component of detonator charges and fire cap firing charges.

However, mercury rhitate has relatively poor stabilisation and is highly toxic, and the firing charge containing mercury rhitate is easy to corrode the gun chamber and cartridge, and has been replaced by another safer lead azide in later generations.

Although Lan Yan knew the process of mercury thunderate, Zhu Zhanji resolutely refused to let her test it himself.

This kind of gunpowder is highly poisonous and has poor stability, if she has an accident, Zhu Zhanji's loss will be great.

And let those gunpowder experts test, two people have died, but they still haven't been able to stabilize this gunpowder.

In addition to the fact that mercury thunderate has not been developed, the other is the production of copper skin for primer, and it is difficult to mass-produce paper-thin copper skin with today's processing technology.

On the contrary, whether it is a round-tipped pistol bullet or a pointed pistol bullet, a batch has been made by hand.

These bullets are all copper-skinned lead-core warheads, and the processing size is strictly in accordance with Zhu Zhanji's requirements.

The cylindrical shell is directly produced by the wire drawing process, and then cut into one by one.

Propellant is not difficult for blue smoke, nitrocellulose smokeless gunpowder can be divided into single-base, double-base, and three-base, and these three types of gunpowder are not difficult.

Blue smoke only gave the processing technology, and the gunpowder master used a mixed solution of purified ethanol and ether to dissolve and gelatinize the nitrocellulose to produce colloidal gunpowder.

Subsequently, the luminous agent graphite and the passivating agent camphor were added to the gunpowder composition to form a safe granular firing gunpowder.

Zhu Zhanji's "failure to do his job" has made many ministers a little dissatisfied, but now is the hottest time of the year, and many ministers themselves have unconsciously reduced their workload.

Although Zhu Zhanji "did not do his job," he did not do anything wrong, and he handled official business on time every morning, but there was no minister who did not open his eyes to him and put forward his opinions.

It wasn't until the beginning of July that the linkage mechanism of the spear was finally finalized, and a Mauser-like spear was produced.

Zhu Zhanji tried his hand, and it was quite good.

Those gunpowder masters finally managed to get less than a pound of mercury thunderate, which was packed into a glass bottle and sent to Zhu Zhanji's private workshop in fear.

There was a big accident on the first day of assembly, because there was no processing equipment for the production of the primer, and it was completely manual.

Although Zhu Zhanji gave thousands of instructions, a craftsman still detonated the bullet when he assembled the primer and the bullet case.

Fortunately, the bullet pierced his calf, and the bullet case collapsed and blinded him in one eye, but his life was saved.

What Zhu Zhanji didn't expect was that not only did this accident not make them afraid, but everyone was excited.

The fact that a bullet has such a power just by hitting it with a hand shows that the power of this bullet is far greater than that of existing muskets.

Because of the previous powder gun, even if it was aimed at a person, it was impossible for the bullet to penetrate the body, and it would only leave the projectile in the person's body, which made people feel painful.

And after a hundred meters, it is basically impossible to kill people.

But now, it's a different story.

Immediately, a researcher asked Zhu Zhanji how long the range of this new gun was. Zhu Zhanji gave them an 800-meter data, which made everyone stunned and couldn't believe it.

In the original history, the range of Mauser 1898 was 800 meters, and today's gunpowder is purer than the original, and Zhu Zhanji is still confident in the range of 800 meters.

Of course, if the effective range can reach 400 meters, he is already very satisfied.

When all the 200 handmade bullets were made, Zhu Zhanji couldn't wait to take the two guns and go to the shooting range of Yulin Weixue for testing.

The test firing of the pistol went very well, because there was only a firing range of fifty meters, and nothing was found to be lacking.

The bullet is stable, although it looks a little astringent because there is no butter, only vegetable oil lubrication, but Zhu Zhanji is already very satisfied.

But the test firing of the spear made Zhu Zhanji frown at the first shot.

The first bullet he tested was fired at a distance of 200 meters, and he could clearly feel that the vibration of the muzzle was too great and the trajectory was unstable.

Although the bullet finally hit the target, it missed the bull's-eye and almost missed the target.

Li Liang's sycophants followed, and he comforted Zhu Zhanji, saying that it was already amazing to be able to hit the target at a distance of 200 meters.

I tried another shot, and this time it was still the same problem.

Zhu Zhanji knew that this was a rifling problem.

He had long forgotten how much rifling was for a gun like Mauser, but because he often played Boletta, he remembered that Boleta had six riflings, and then it was right-handed, with a wrapping distance of 250 mm.

The so-called rifling is also called compound wire. The degree of rotation of the incoming and returning lines is called the wrap distance.

If you need to travel longer distances to complete a 360-degree rotation, it is called slow; The shorter one is called fast.

For example, completing a lap in less than 12 inches is slower than completing a lap in 9 inches.

The difference in the length of the winding mainly lies in whether the warhead can be stabilized, and the unstable warhead will not only rotate along the target line, but also turn over the heel bucket, resulting in a keyhole phenomenon on the target paper.

Zhu Zhanji didn't know that the rifling distance of Mauser's spear was only slightly longer than that of a pistol, but it seemed that it was far from enough.

However, this problem is easy to solve, dozens of such barrels have been produced, and then try with other entanglements, and you can always find the most suitable entanglement.

As soon as I told a few craftsmen about this problem, they immediately rushed to rework.

Zhu Zhanji left the long gun bullets, took all the short gun bullets away, and ordered Li Liang. "Count how many dukes and counts of Ying Tianfu are in Beijing, and let them all come to Yulin Weixue to appreciate the new guns in three days. In addition, all the officials above the fourth rank of the five cities and the five military governors were also called. ”

Zhu Zhanji's purpose is not to sell new guns, but because the emergence of a new type of weapon will trigger changes in the battlefield situation.

Holding a broadsword and spear to fight the enemy is a formation, and fighting the enemy with a firearm is another formation.

Now that there are better weapons, and in the future, large-scale rearmament, the command concept of the army will also change.

It was only when these generals embraced the new way of warfare that it became widespread.

Otherwise, just the advanced weapons may not be able to beat the millet plus rifle.

was about to return to the palace, but saw several figures running over quickly.

Zhu Zhanji looked at it, but it was Liu Wan, whom he hadn't seen for several months.

He trotted all the way, and was still five steps away from Zhu Zhanji, and then knelt on the ground. "Your Highness, the slave is back."

Zhu Zhanji saw him tanned, and said with a smile: "I haven't seen him for a few months, and the little white face has become a big black face." However, it looks a little heroic now. ”

Li Liang next to him touched his white and tender face, and said secretly in his heart: "What a mistake, originally for the sake of image, I specially stored white, but I didn't expect that His Highness prefers to be heroic." Maybe His Highness has a beard, so he prefers the one with a beard. However, without the balls, the slave and the maid can't grow a beard! ”

Seeing Liu Wan, who he hadn't seen for a long time, Zhu Zhanji's heart was also very happy, after all, this is also a playmate who grew up with him since childhood. He handed him the pistol and bullets and said, "Get up, hold it steady for Lone." When I go back to the palace, I will ask you what you have done in the past few months. ”

Liu Wan
