Joseph was indeed burying himself in the laboratory and looking like something new, that is, he was going to hand over to Napoleon for his new toy Minnie rifle for use in Italy.

In this era, there were already rifled rifles. However, these rifled rifles, because the reloading speed is too low, are almost useless except hunting. (The bullets of the original rifled rifles were slightly thicker than the barrel, so when loading bullets, the gun holder had to use a hammer and push rod to stab the bullet into the barrel with difficulty. This process was so time-consuming that ordinary smoothbore rifles often had seven or eight shots, and only one shot could be shot by a rifled rifle)

But the appearance of the Minnie bomb changed all this.

In original history, this bullet was invented by French captain Claude Erne Miner and Captain Henry Gustav Dewikine around 1849.

This kind of bullet is slightly smaller than the rifle's caliber, so it solves the embarrassing situation when the old rifle is loaded in front of the bullet, and the barrel cannot be plugged in or blocked due to the large bullet. The Minnie bullet can easily be pushed into the barrel with the push rod, thus greatly increasing the firing rate.

The bullet carries out threads around the bullet body to match the rifle, and puts animal oil in the middle of the thread lubrication. (Later, the British also learned this technique and brought it to India. However, they did not expect that the Indian soldiers refused to use it because of the lard or butter on these bullets. This was used as a fuse to trigger a great Indian national uprising.)

Cork material is used at the bottom of the bullet. When firing, gunpowder gas impacts the cork, and the cork suddenly supports the bullet after being hit instantly. Since the bullet is supported, the bullet itself can be used to complete the sealing of the chamber at the moment of launch without leaking the gunpowder gas, causing the loss of kinetic energy of the bullet. This solves the problem of the chamber sealing of the old-style front-loading gun, greatly enhancing the rate of fire, range and safety of the gun (good sealing is not easy to cause the residue of gunpowder residue to block the barrel and cause the explosion).

Although this kind of bullet was invented decades later, it is actually not difficult to implement it technically at this time. However, the advantages it brings in tacticality are very huge.

First of all, it completely catches up with the smoothbore gun in terms of loading speed, making the only advantage of being a weapon that is cheaper.

A general smoothbore rifle has an effective range of no more than one hundred yards, but a rifled rifle with Minnie can effectively shoot targets with a temperature of 500 yards away. This has lengthened the firepower arm of the rifle in the hands of infantry many times.

Before using this kind of bullet, both the British and Russians believed that "bullets are fools, and bayonets are heroes." They were accustomed to pushing their opponents' bullets to the nearest distance on the battlefield, and then after another volley, they used bayonets to charge to solve the problem. However, if their opponents used Minnie bullets that could effectively shoot at 500 yards, then the bravery of both the British and Russian troops would become a joke. The status of hand-to-hand combat also declined sharply.

In the era of smoothbore guns, infantry had to line up in a strict formation due to the threat of cavalry (of course, in addition to this reason, the morale of the army is also a major reason. If the morale is not enough, the scattered soldiers will really disappear on the battlefield once they disperse.), but with the Minnie bombs, the cavalry will charge towards the infantry again, which will be a death sentence. The status of cavalry has also declined significantly.

In addition, the artillery tactics were also greatly affected. In the era of smoothbore guns, when the cannon was used with shotguns or grape bullets, its effective range was greater than the rifle in the hands of the infantry. Therefore, the cannons can be used as offensive weapons in field battles and pushed at the front of the queue.

However, the emergence of Minnie bombs made the range of infantry weapons suddenly exceed the range of cannon's shotgun or grape bombs. Although the range of solid cannons used is much further than that of Minnie bombs, due to accuracy, it is too efficient to use it to attack loose scattered soldiers. Therefore, if the cannon is pushed in front of the attack at this time, the gunner will become a living target for the opponent's infantry. Therefore, the cannon has to retreat and only be used as a supporting weapon in large logarithmic times.

Even the little melon, which has changed the historical process, will return to the auxiliary weapon position due to the throwing distance problem, from the current position that is almost about to become a main weapon.

However, this weapon still has a huge flaw, that is, its technical threshold is too low, so you can understand what is going on with just a glance. Therefore, once this weapon is used, it will not take long, and the relevant technology will definitely be obtained by others. These people may be enemies of France or the Bonaparte family in business.

Therefore, this thing can only be put into use before Napoleon enters Italy. The Bonaparte family relies on the victory and support brought by this weapon to reach political high positions, and use this position to suppress and defeat their business enemies.

Of course, Joseph, as a time traveler, naturally knew that this weapon would eventually be replaced by a bolt-action rifle installed in the back. He did not intend to squeeze toothpaste. It was just that some of the pre-engine technologies for bolt-action rifles were still difficult to achieve today. For example, bolt-action rifles must use steel instead of iron, but in this era, the world's most advanced steelmaking technique is still crucible steelmaking. Its output and efficiency cannot meet the requirements at all.

The bullet experiment was actually successful very early, but the design of the rifle dragged a little bit. The Minnie bullet needed gunpowder gas to support the bullet, which means it needed to use gunpowder with faster combustion speed. It is not difficult to achieve just that the combustion speed is faster, but the faster combustion speed will bring two problems. One is that the chamber pressure rises too fast, and the other is that the chamber pressure drops too fast. The former causes the chamber pressure to peak at a high level, which is easy to explode. The latter causes the chamber pressure to be not high enough and the bullet speed is not fast enough.

In order to avoid blowing, the barrel must be thickened, which will make the rifle too heavy and consume too much metal, increasing the cost. For this reason, Joseph designed the barrel as a round table with thick back and thin front, but the thicker place should be and how thin it can be, can only be solved slowly by experiments. Therefore, these things that are not difficult in principle take up a lot of time for Joseph. So the number of words he wrote to Fanny was reduced.

However, no matter how busy you are, you should pay attention to the combination of work and rest. At least, mental workers must do this. So Joseph stipulates that researchers will have a day off every ten days, and work no more than 12 hours a day. As for senior researchers like himself and Lavoisier, they will have two days off every ten days, and work no more than six hours a day. As for physical workers, there are all over the streets, unless they are particularly skilled and so difficult to replace, Joseph has no time to care for them.

Today was not a break, but Joseph received a letter from Lucien saying that a millionaire was going to talk to him about a big deal. So Joseph handed over the institute to Lavoisier and rushed back to Marseille. He met Stephen Gillard in the Marseille manor.

Joseph only knows about history. He didn't even know anyone in his previous life, so naturally he wouldn't know that the bald man in Bordeaux tasted in front of him was a legend in American history. Stephen Gillard, who started his business by smuggling arms for the Continental Army during the North American War of Independence, was the shipping king of North America and the first mogul in American history with a personal asset of more than 10 million US dollars. However, this was something that happened later. At this time, it was just when his hegemony had just taken off.

Stephen Gillard was a sailor and was particularly interested in all kinds of ships. When he first saw the "Black Pearl" in the port of New York, he was full of interest in it. After a little understanding of the performance of the "Black Pearl", he immediately calculated that if the load capacity of this ship could reach 500 tons, its efficiency would be far beyond the conclusion of ordinary sailing ships. So, the French-American with a sensitive sense of smell returned to France with the "Black Pearl".

In the next two days, Joseph and Stephen Gillard had a arduous negotiation. Both sides cried and poured chicken soup to each other, and said that "the negotiations enhanced the understanding between the two sides." Finally, a strategic partnership was reached.

According to the final agreement signed by both parties, Stephen Gillard will order seven fly-scissors with a load of 500 tons at one time from the shipyard affiliated to the Bonaparte Institute, and prepay all the purchase price for five of them. The remaining amount will be paid when the ship is delivered.

Bonaparte shipyard needs to transfer the technology related to the construction of this kind of fly-scissors to Stephen Gillard, and ensure that if Stephen Gillard provides no less than 1.5 times the salary of employees in the French industry, technical guidance personnel will be sent to Stephen Gillard's shipyard in New York, and ensure that the New York Gillard shipyard can master the manufacturing technology of fly-scissors within two years.

Stephen Gillard promises that for every fly-scissor ship produced in Gillard shipyard will deliver technology usage fees to the Bonaparte Institute for every lift ship produced in the next fifteen years.
