With Rihachi's understanding, Naohide was able to arrange for the happy event Shigeya to make jams, gummies and jelly independently, and the most important thing was that the three hundred taels of gold tickets were in hand, and the heavy gift to Mr. Tanan of Abe Ise Moriwa was finally settled.

"Promoted to make a fortune, I think it is a promotion to break the wealth", Zhixiu relies on the coquettish flag, but this thank you gift can't be saved. Originally, he wanted to give Abe Ise Mamoru 100 taels and Mr. Tanan 200 taels, but as soon as the cold wind blew on the road, he was honest - Nagasaki Lankoku Shokan asked for money to buy books, Yuan Lian asked for money, and after the New Year, the Mizuki Shoku School in Tosa Kochi is expected to cost a lot of money, so he can't afford to send it.

Naohide returns to Shinjuku first, and then takes two students to exchange the sentence - close to the New Year, Edo is flooded with thieves and "little monks", and he has to be guarded against. After that, I went to Oguri's house to leave a letter and a gift.,Before the two said yes.,Because Naohide can't go to the city for no reason.,I can only ask Oguri Hall to hand over the gift to Abe Isemori, who lives in the mouth of Tatsuno.,The gift is in addition to some valuable gifts and two large judgments.。

After that, Naoxiu went to Mr. Egawa Tanan's mansion with the package again, but it turned out that Mr. Egawa's son Yingmin came forward to receive him, so he could only gossip and leave gifts, but this time it was empty again.

After running a few more times, on the morning of the 28th of the wax month, Naoxiu finally met Mr. Tan'an. In fact, Mr. Tanan returned to Edo on the 226th, but because he visited and visited the high-ranking officials of the shogunate, he basically drank from morning to night, and only now did he have a slight time.

"Naoxiu thanks the teacher, grateful, great grace is in the bottom of my heart", Naohide is sincerely grateful to Mr. Tan'an, he was from a humble background, and he can get Mr. Tan'an's blue eyes, this is not the ancestral tomb with blue eyes, this is the smoke billowing and the red light is rushing to the sky - he doesn't know what Mr. Tan'an wrote in the report of the commission, it stands to reason that Egawa's subordinates also have a large number of subordinates such as the town commissioner, the county commissioner, and the head of the land, and they have to line up for promotion and fortune, but according to Oguri Tadashun, Mr. Tan'an ranked himself first on the list of meritorious service, which is not easy, Mr. Tanan is not afraid of his subordinates rebelling?

"Get up, don't be a child", Mr. Tan'an has always been close to Naoxiu. Next, Mr. Tanan criticized Naoxiu a few words, which was nothing more than saying something "too expensive" about the three big judgments for the gifts left two days ago - Mr. Tanan and Xiaokuri Hall were rare gentlemen at that time, who were very strict with themselves and rarely accepted expensive gifts.

Then, Mr. Tanan praised the quality of the orchid books sent by Naoxiu this time, coke, fireproof bricks, cement, red bricks, blue bricks, etc. are very practical, and the value of other orchids is also very high--Jiangchuan private school "Rope Martial Arts Hall" has always had the habit of collecting orchid books.

Listening to Mr. Tan'an's words, Naoxiu was taken aback, and he hurriedly tested, "Sir, it's a pity that the "Wangjialaike Artillery Casting Method" still hasn't been started."

Mr. Tanan also expressed regret, and Naohide breathed a sigh of relief - it seems that Mr. Tanan didn't get this book when he was in the Edo Senate of the Lankoku Merchant House last time, and I hope he won't be able to get it this year, why does Naohide think so? Because manufacturing a reverberatory furnace is too time-consuming and costly, and too risky.

In the future, Saga built a reverberatory furnace, and from 1850 to 1852, it is said that the first reverberatory furnace was revised eighteen times in a row, but the result was still a failure, and then five more were built in a row before finally succeeding. How much did it cost? Folklore has it that it is 50,000 taels of gold!

At the same time, Egawa Tanan was also building a reverberatory furnace in Nirayama, which was an official project of the shogunate, how long did it last? It was completed from 1850 to 1857, and in the middle of the construction, Mr. Tanan fell ill and died in 1855, and the heir of the Egawa family, Egawa Hidetoshi, took over and continued the construction. The quality of the reverberatory furnaces was mediocre, and it was discontinued in 1864.

As for why Saga did not transfer the technology to the shogunate after the successful construction of the reverberatory furnace, first, the construction of Saga's reverberatory furnace was not very good, and a lot of experience was relied on, and the specific details were not clear; The second is that the shogunate and Mr. Tanan could not wipe their face and asked for help from the Saga Domain, and at the beginning of the construction of the reverberatory furnace in Saga, he specially sent people to Mr. Tanan to study, but as a result, the apprentices of the church starved to death of the master, and Saga succeeded in building Nirayama before him. After Mr. Tanan died of exhaustion, the Saga clan immediately sent someone to Nirayama to pay homage and provide technical support, and Saga eventually shared the technology.

According to Naohide's analysis, the advantage of Saga's construction of the reverberatory furnace is that in addition to the refined Shichijie cowhide led by Totao Motoshima and Yosuke Sugitani, the unity of the Saga clan was also very important, and Mr. Tanan had many part-time jobs and scattered energy, for example, "Edo Odaiba" was built by Mr. Tanan at the same time, and this distraction was not easy to do.

In addition, Saga also has a good location. The large coal mines of Fuso are located in the northern part of Kyushu Island and the western part of Ezo Prefecture, and the Saga Domain uses high-quality coal from the Takashima Coal Mine, while Nirayama uses the coal produced by the coal mines in the northern Kanto Plain.

In addition, the sources of iron ore in the two places were also different, and the Saga Domain was more clever, and at the beginning it used high-quality iron sand from the "Chugoku region" of Honshu Island, and did not use the inferior iron sand of Kyushu Island at all, while Nirayama discovered the problem of iron sand later, and switched to high-quality iron sand from the southern domain, which contained more phosphorus and sulfur, and the quality of cast iron was poor.

The explanation is to cover up his incompetence, anyway, in the future, Mr. Egawa Tanan has planted a big heel in the construction of the reverberatory furnace, and it can basically be said that the evening is not guaranteed and his reputation is ruined.

Naohide doesn't want his teacher to repeat the mistakes of the past, so he can't get Mr. Tanan to start building the reverberatory furnace unless he participates. But Naohide didn't know that Mr. Tan'an had given him the task of building a reverberatory furnace by default.

Mr. Tanan is forty-four years old this year, and although he can't say that he is old and frail, he already feels that his energy is not as good as before, and his most proud Lanxue student Sakuma Xiangshan is more interested in governance and the military system, so he pins his hopes on Naoxiu for the practice of Lanxue - after all, not every Lanxue student is playing with gold fat, the taste is sourced and unique, and it is pragmatic to be able to persist in producing results; In addition, the wind is regarded as a symbol of disaster in Fuso, and only Naohide "Daring" used him as motivation, and he succeeded. Since ancient times, if the official army is defeated, it will be a thief, if you can't do it, it will be reckless and sudden, and if you do it, you will be bold and careful - hanging with its own halo is not explained.

Naohide has a lot to say to Mr. Tanan, but he doesn't know where to start.

First of all, Mr. Tan'an is a little naïve in politics, "do big things without sparing your life", this is true, but it is also divided into the environment, the upper and lower are united, and it is okay to make achievements after doing it, if there is doubt up and down, there are so many spicy delays, "doing big things without sparing your body" is directly equivalent to "not sparing your body", it is cool and fast. But is the identity of Zhixiu, a low-level flag, and the world too "rampant" to talk about the world in this conservative atmosphere? So you can't say it, you can only "drag it off" in advance - don't start doing it.

Secondly, Mr. Tanan is the highest-ranking shogune that Naohide can approach - Oguri Tadashun has not yet taken over as the head of the family, so he can only play soy sauce by the side of Gongfang. Previously, Naohide promoted advanced agricultural postures through Mr. Tanan, and this year through Mr. Tan'an, and now there are a little more than eight years left before the first visit of the black ship, what gaps can be made up through Mr. Tanan during this time?

What is the difference between Fuso and Europa countries? The Tokugawa shogunate repelled many foreign warships and armed sailing ships during its lockdown, but why did it suddenly kneel in 1853? Could it be that something was wrong with the shogunate before 1853?

There were really no major problems, and between now and 1853, the Fuso and shogunate were basically developing steadily, and there was no major upheaval. The Battle of Canton in England and China took place in 1840-1842, and after more than ten years, Fuso has recovered from the fear at the beginning.

So what's the difference?

In fact, it was just a wheel away - in the past, it was all sail warships that broke into the waters of Fuso to ask for the opening of the port, and among the four warships visited by the black ships, there were the cruiser Saaskehana and the cruiser Saskehana, and these two battleships were out-wheeled fast sailing ships. What does it mean? That is, these two ships are steam sail warships, and after installing paddle wheels, their mobility has increased greatly, and they can make trouble in Edo Bay. In the past, the maneuverability of the sail battleship was mainly based on the face, and the wind direction and speed were suitable and the maneuverability was good, but if God did not give face and sailed slowly, it would not be advantageous to get the benefit from the "Odaiba", the battery of the Uraga Commission, the narrow entrance to Edo Bay.

Of course, the gap in the artillery of the two sides is also growing. Since the invention of the reverberatory furnace in 1784 by the English Henry Court, Europa's iron cannons have gradually surpassed the bronze cannons of the East.

The performance of the gun depends on the size of the muzzle, the size of the muzzle represents the range and power - this sentence is wrong, or at least not completely true, the performance of the gun has the firing range, range, power, rate of fire and durability, and these are determined by the material of the gun, structural design, firing - charge, cannon ammunition, shell structure design, etc., to put it mildly, the performance of the steel is good, the rifling is unreasonable, the barrel is not tight, the gun breech is not smooth, the gun latch is good, whether the brake is regression machine, Whether the pointed shell has been studied, whether it is a flowering shell, what is fired - what is medicinal, what is used for artillery ammunition - it is enough to talk about the artillery of the 19th century.

In 1774, the English Wilkinson (full name John Wilkinson) invented a more precise boring machine for gun barrels. The following year, he used this barrel boring machine to bored cylinders to meet the requirements of the Watt steam engine. In order to build larger cylinders, he built a cylinder boring machine driven by a water wheel in 1775, which promoted the development of steam engines. From then on, the machine was driven by a steam engine and a crankshaft.

In 1799, E.C. Howard produced mercury thunderate. In 1814, mercury thunderate began to be used to make fire caps, becoming the first detonating charge to be discovered.

In 1803, the shrapnel (flowering shell) invented by Shrapnel, a lieutenant of the English artillery, appeared on the battlefield and increased the power of artillery.

In 1823 the practical blaster naval cannon "Bombardment", invented by the Flannish general Henri-oseph Paixhans.

In 1836, the English ship "Archimedes" had an accident during sea trials, and the inspired shipbuilder invented the propeller. In 1842-1843, John Erickson, the inventor of Reading, built the world's first propeller-driven warship for the US Navy, the gunboat "Princeton". By 1860, propellers were already unique on seagoing vessels.

In 1846, Major Cavelli of the Kingdom of Sardinia made a revolutionary leap in artillery technology when he created a breech-mounted cannon with two rotating lines engraved into the bore and a pointed column for the shells.

In the 40s of the 19th century, the steam propeller battleship "Royal Monarch" no longer had masts and sails, and the 120 guns were reduced to 5, and this odd-shaped hybrid battleship became the origin of modern warships.

By 1850, the sail battleship began to give way to the hybrid sail--steam battleship.

During the Crimean War in 1854, the English arms designer Armstrong designed an experimental 3-pounder breech-loading rifled gun, with the advent of the wedge-type gun latch, after which the breech gun began to gradually replace the breech gun.

In 1856, the English Besmarck invented the bottom-blowing acid converter steelmaking method, which was the beginning of modern steelmaking.

The first ironclad ship, the "Glory" ironclad ship of France, was built in 1858, completed on November 24, 1859, and commissioned in August 1860, which laid the foundation for the development of ironclad warships in various countries in the future.

In 1873, the Krupp company of the independent country began to add quilt covers (i.e., barrels and tight barrels) to the guns, and the value of the Krupp cannon doubled from then on.

In 1897, the French Moa pioneered the water-pressure gas brake and retreat machine, and the artillery entered the era of tube retreat from the era of frame retreat.

In 1888, Nobel invented granular smokeless gunpowder, after which smokeless gunpowder was used as a firing explosive for guns. The previous firing was a maroon powder made from black gunpowder after water vapor passivation.

But it's still early, in 1853 the black ship of the United States was still an out-wheeled wooden hybrid sailing ship, and most of the naval guns were still front-loading smoothbore iron guns, which could fire solid cannonballs, flowering shells, chain shells and shotguns, with an effective range of between 0.5 km and 3 km, and the best firing distance was within 1 km. The Kangreve rocket carried with the ship has a range of up to 4,572 meters.

The maximum firing range of the bronze cannon is 5 km, and the effective firing range is also within 1 km.

Therefore, when the black ships visited, the shogunate's fort "Odaiba" was not without the power to fight back. Later, in 1863, the English warships bombarded Kagoshima, and although the Satsuma clan suffered heavy losses, the captain of the English flagship was killed by shore guns, and the English killed and wounded a total of 60 people, and Kagoshima died 9 people, and it is said that the battle distance at that time was about one kilometer.

However, the shogunate had been peaceful for a long time, and the armament was lax, and the bronze cannon was made of clay molds, and there were many impurities in the barrel, and there were many air bubbles in the pores, and the amount of nitrate was too high, the impurities were too high, and the particles were coarse.

In fact, these are only the weapons gap on the surface, the real gap is: the first industrial revolution ended, with the first completion of the industrial revolution in England around 1840, major industrial countries such as France and the United States entered the industrial society in the middle of the 19th century, and their strength was greatly expanded, and the agricultural civilization of East Asia began to form a generation gap.

At this time, there was almost no heavy industry in Fuso, the mining industry was still very primitive, especially the coal mine was not developed, the light industry except for a few hydraulic textile workshops, the rest were handicrafts, there were no trains, large ships were not allowed to be built, cattle and horses were small, and the machinery industry was even more miserable, until 1856, Fuso introduced the first machine tool - Mausdre Bicycle Lathe.

The hardware can hardly be said to be poor and white, this is all white, nothing. As for software, the development of science and technology has stagnated, class mobility and human mobility have been banned, human rule is the main mode of social governance, the society that adopts the irregular time system has no accurate concept of time, the social atmosphere is retained, Confucian scholars are still preaching the set of fathers and sons, monarchs and ministers, and education is extremely backward.

Later generations said that the literacy rate of the Edo population was 40%, but the samurai and families in Edo Castle accounted for nearly half of the population, and at least 20% of the samurai family members in Edo were illiterate! Considering that the literacy rate of the merchants and townspeople in Edo is very high, the illiteracy rate among the samurai family members in Edo is even higher, possibly 35%! Edo was the most prosperous city at this time, and 20%-35% of the samurai family members were illiterate, so the peasants, who made up 80% of the population of Fuso, were not as good as the samurai, and it was estimated that they could have a literacy rate of 10%.

What's the difference? Almost speechless, it's all bad, the overall gap, the difference between cloud and mud. But the desperate situation has inspired the ferocity of Zhixiu, "rise and destroy the country, follow the peerless, and lift the people", the big husband must do something, this is Zhixiu's determination and belief.
