On the 15th day of the third month of Yayoi, on a hillside outside the town of Nirayama in Izu Province, Naohide and Rihachi were enjoying the cherry blossoms while sitting on a mat and slowly sipping sencha while the wind blew the pink cherry blossoms like rain.

The cherry blossoms near Izuta Onsen bloom early, but due to the mountainous nature, the cherry blossoms bloom late in some mountainous areas, so it is a surprise that you can see cherry blossoms at this time.

A short time later, in the distance, a group of "middle" (retinue) and "minor" (servants) surrounded the two nobles and walked up the hillside, and Rihachi and Naohide hurriedly got up to greet them.

Mr. Egawa Tanan walked in front of him, Oguri Tadashun was slightly behind, followed by a group of samurai and servants, and Naohide also saw Sakuma repairs of Zoyama Academy in the crowd.

Mr. Tanan nodded to Naohide and Rihachi, who came to greet him, and his eyes focused directly on the behemoth on the hillside, only to see a lot of wooden wind blades forming a huge chrysanthemum, the chrysanthemum rotated rapidly with the wind, and there was a long wooden tail behind it to automatically adjust the wind direction, and below was a wooden tower three or four feet high, which was quite amazing.

Using gears and drive shafts, a windmill can drive several stone mills to work together, and flour is produced in a steady stream, and Mr. Tanan and Oguri Tadashun keep nodding. Liba took the opportunity to introduce that it had been running for three days, and there had been no failures during the period, and Mr. Tanan asked a few more questions, and the on-site viewing was over.

Taking advantage of the time when Mr. Tanan and Oguri Tadashun sat down to drink tea, Rihachi hurriedly asked people to serve a variety of flour elaborate Karashi fruits, and presented noodles such as dried noodles, stuffed steamed buns, steamed buns, steamed buns, etc., and several board front (chefs) also performed live to make steamed buns, ramen, dumplings, and pancakes, and everyone was very interested in watching it, and the samurai who followed under the orders of Mr. Tanan and Oguri tasted it and praised it.

Naoxiu secretly laughed in his heart, these samurai who are used to eating rice may not be able to eat good pasta, at most they will eat fresh, but everyone has to cheer on the master, saying that it is not delicious is not that they don't want to mix.

After the excitement, Mr. Tanan called Naoxiu to his side and told him a few words about the study tour, and then he took people away. Oguri Tadashun called Lihachi to his side and told him to "do things well", and Lihachi agreed with a smile, and the matter of windmill promotion was settled.

To be honest, Naoxiu hasn't experienced any grand scenes since he arrived in this world, and this time it's an eye-opener. Although he has also experienced a large scene of more than 100,000 people in his previous life, but a group of samurai in front of him are serving respectfully, and Naohide is inevitably a little nervous, which is very different from the situation of meeting with Mr. Tanan in private, it seems that he still needs to exercise, this small scene is tense, it is really a bit embarrassing to lose the face of the predecessor of the traverser.

The first windmill began to be used, and the after-sales service of Zhixiu was completely completed, and there was no relationship between how much money Liba earned and Zhixiu's copper money. On the way back, Naohide and the two students complained bitterly, Izu's dimples really can't stand it - Izu's roads are very poor, and the locals call the big potholes on the road Izu's dimples, according to Naohide's idea, it should be called Izu's pockmarks, and there is only one pair of dimples, which is obviously not in line with the facts. It was only when you got to Tokai Road, one of the five streets of Edo, that the road conditions improved, and Tokai Road was truly a "national highway" at this time.

Before, Naoxiu had accompanied Yingzi to celebrate the "Hina Festival" of the Daughter's Day, and swept the tombs of his ancestors on the day of the spring equinox.

During this time, Yingzi was immersed in a beautiful love, and she received a gorgeous doll from Naohide at the Hina Festival, when Naohide flattered her girlfriend with her highest guiding ideology, and praised the loose sushi rice and clam soup with Yusuke, and there was no need to say much about many romantic actions. She was very reluctant to leave Naoxiu, but women in this era respected men very much, she just told her a thousand times when she parted, and she also gave Gakujiro a secret mission, Naohide only felt cold on his back.

This study tour is still Naohide, Toranosuke, and Gakujiro, and after arriving in Osaka by sea, they visited Mr. Ogata Hongan, and after three days of lectures in Shikijuku, the three of them went straight to Shimonoseki by boat.

Shoichiro Shiraishi, a wealthy businessman, was sitting at home sulking, since he met Naohide, all kinds of trivial things continued, no, a guy named Murata Eitoshi came over with Naohide's letter to eat and drink for nothing. Shiraishi is a social person, and he doesn't care about this because he eats and drinks for nothing, but this Murata not only looks weird and behaves very specially, not annoying, but he can't chat with him, often after three sentences, he is choked by Murata, and he can't talk anymore, Shiraishi is proud of his talkativeness, but Murata makes him wonder if his judgment of his talkative is wrong.

So as soon as the servant informed Naohide of his visit, he hurried to greet him - usually there are few people worthy of Lord Shiraishi taking the initiative to greet him, and after the visit, Murata Yongmin carried a small burden and left with Naohide, thank God.

Yongmin and Naoxiu have been separated for nearly five months, but he is not seen at all, and after they met, he carried the bookcase to himself, did not ask anything, and did not say anything, with the attitude of an uncle who left the rest to you, and made Naoxiu and the two students angry.

After breaking up in Xiaguan last time, after Yongmin returned to the village directly, he handed over the ten small judgments given by Zhixiu to his father, and Xiaoyi, the head of the Murata family, was stunned all of a sudden, his son He understands that he is really smart, but he can still make money by going out to study, this is strange, could it be that medical skills have grown greatly? He took the test and taught Yongmin, and felt that he didn't grow into a loss of conscience, but the level was just like that, and he couldn't cure the disease and couldn't heal the dead, and after asking, he learned that Yongmin worshipped an orchid scholar as a teacher, this person is quite rich, and he knows Mr. Yokoi Xiaonan, and it is said that he is still a disciple of Mr. Ito Xuanpu, okay, it's better than staying at home, anyway, this son can't teach himself, so he can only rely on other gentlemen.

Naohide and Murata made an appointment to meet in Shimonoseki in the first half of the month, and when the time came, Yongmin took Naohide's letter to Shiraishi Shoichiro, and Naohide asked Shiraishi to take care of Murata in the letter, and did not let Shiraishi entertain him, but Shiraishi said more, "If you don't dislike it, please recuperate in this house", Murata heard that it was very good, so he stayed directly.

The four of them have been separated for a long time, but they are not polite to Yongmin, and they can't be polite, this master doesn't like to talk.

Shimonoseki was an important place for shipping, so they found a boat along the way and went straight to Nagasaki, and when they arrived in Nagasaki, they met with Ranok Nakata and asked him to hand over a gift to Dr. De Vries of the Rankoku Shokan. Hearing that Naohide was going to Shikoku Island, Nakamura Taichi asked him to bring a letter to Ishii Muneken of Uwajima, and Naohide casually agreed.

Another acquaintance in Nagasaki was Taro Matsumae of Nagasaki Metoko, Naohide brought him a letter from home, Matsumae was very happy, and then Naohide asked him to buy some seeds through a Chinese merchant, and only after showing a letter from Taro Saemon, the acting official of Izu Nirayama, did he agree to give it a try.

In the past, the shogunate did not prohibit the import of plant seeds, but later because some merchants bought good seeds from overseas, which caused certain losses to the privileged merchants of the shogunate, the shogunate began to prohibit the import of plant seeds from overseas. Naoxiu thinks that this is a problem with the brain, how good it is to introduce good breeds, and for the sake of profit, it is actually forbidden to import good breeds, is this something that normal humans can do?

After finishing the errands, Naohide and his party went straight to Saga, unlike last time, this time Naohide was going to stay in Saga for a few more months, at least get the glass out and then leave, and by the way, he also translated the orchid book in his hand and printed a few more copies.

Mr. Xuan Pu was very happy to translate Lan Shu in Lan Xueliao, Zhixiu inquired, the fire magic prescription has not yet been established, Lan Xueliao is still under the management of the medical museum, Mr. Xuan Pu is the three major Lan prescription doctors at this time, his medical skills are exquisite, and his status in the medical museum is quite transcendent.

The last time Naohide visited Saga, he introduced wax paper printing, but at that time it was ink, and the effect was not satisfactory. Ink, like ink, contains color agents, connecting agents and fillers, and also has a certain viscosity and fluidity, but the ink diffusion is relatively fast when printing on wax paper, and it is not as easy to use as ink.

Naohide left behind the ink when he left, which was to boil linseed oil, let it cool, add a small amount of turpentine and carbon black obtained by distilling pine resin, stir it well, and then leave it for several months. Naohide also asked Mr. Genpo to try rapeseed oil on the island of Kyushu. When I came back this time, I found that the ink had been cured, and the effect of wax paper printing had improved a lot.

The abacus daimyo Nabeshima Saimasa is worthy of falling into the eyes of money, he heard that there is a windmill model in Rangakuliao and took it to watch, and then sent someone to build the first windmill - Naohide worked hard in Edo to make it, Saga Domain actually built it with reference to the model, you must know that the model left at that time was used to lift water, if it is changed to a windmill mill, a large gear and a rotating shaft will be added. Naohide sighed that he couldn't ignore the heroes of the world, and when he asked who presided over the construction, it was actually someone he knew, Sano Eitobuki, Shimatuan Uemon presided, and the students of the "Windmill Group" of the Orchid Group of the Kodokan assisted, and of course, some craftsmen who could build waterwheels were invited to help.

The Saga Domain had a strong water power, but it was often flooded, and the development of waterwheels was limited, but the development of windmills still had a certain future.

Last time, Naoxiu won the title of lecture in the medical hall, so while Lan Xueliao was translating Lan Shu, he was also teaching students in the medical hall. Naoxiu doesn't have much research on medicine, he is very self-aware, he just knows some medical knowledge, and it is absolutely impossible to cure diseases, so he only lectures on orchidism, once every three days, and the students of the medical hall sometimes come to listen with curiosity, and the students who often participate slowly become mainly members of the windmill group of the Hongdao Museum.

Naohide's curriculum was mainly elementary mathematics, middle school physics, and middle school chemistry in later generations, and in order to deepen his impression, he added a lot of hands-on content, and because it was lively and interesting, he gradually became famous in Kodokan.

Among them, the paper corona is especially popular. Fuso now uses the irregular method of timekeeping, and relies on the taiko drums of Saga Castle and the bells of nearby temples to tell the time. This method can't be said to be bad, it has been used for so long since ancient times, and everyone is used to it. But the corona is more convenient, hang it on the wall, and you can have an accurate idea of the time as soon as you look up.

The paper corona is very simple, a piece of paper and a wooden stick can be used, and the paper is divided evenly into various time points for labeling. The disadvantage of the corona is that it must rely on sunlight and cannot be used for cloudy days and dark nights, but everyone says that the advantages are outstanding, so the disadvantages are relatively tolerable.

By making paper corona, Naohide popularized the ruler, triangle and compass, which were made of bamboo, a little rougher, but easy to use.

In terms of teaching methods, the topic method is adopted, leaving a small question directly after each lecture, allowing students to think about and answer them after class, and students take turns to explain in the next class. Here we have to mention the deported Dr. Siebold of the Lan Guo Commercial Hall, who adopted this method when he was teaching students in Fuso, which broke the rote memorization method of traditional education in Fuso, and made great contributions.

Through the small project after class, Naohide found the location of the nearby clay mine, quartz placer mine, feldspar mine and dolomite mine, of course, it was not found by the students, the students found samples or inquired about the news, and Naohide went to the site to check before it was determined, and it took a lot of effort in the middle.

The students also wondered what they were looking for these ores, but Naohide made it clear to them that these were the raw materials for firing red bricks and glass, and after the news spread, it was said that they had the support of the Saga Domain, otherwise they would not have found all of them in a month.

Not long after searching for all the materials, Mr. Yoshishun Itomoto and Mr. Ito Genpo of the Medical Museum officially invited Naohide to help make glass on behalf of the Saga Domain, and the Saga Domain came forward to assist with the assistance of Hamuro Heinoyoshi, Shiba Sadenta, and Motoshima Fuji Taio. During the banquet, Naohide said that there was still one thing missing, and that was coke, and Totao Motoshima proudly replied that the coke had been made according to the simmering method that Naohide said last time.
