Yang Wenli's development of plumbing facilities was developed together with the production equipment and production line, so in fact, there is no problem with mass production, just waiting for iron ore.

It must be emphasized that because of the limited conditions, Yang Wenli did not develop the boiler of the previous generations, but directly developed the water tube boiler, the water and water vapor of the water tube boiler are circulated in the water pipe, and the U-shaped bend is bent in the boiler, and the coal is heated below to produce high temperature and high pressure water vapor, and the boiler shell is very simple, and even does not need a steel shell, and it is made of refractory bricks, and the water pipe can be connected by wire, so that there is no need for welding technology.

In this way, under the indiscriminate interference of Yang Wenli, a reborn person, the city of Sapporo was used for urban central heating projects hundreds of years ahead of history.

The first user is, of course, the Far Eastern Palace, which is as warm as spring in its clean and spacious interior when the boiler is filled with coal, in stark contrast to the freezing climate of the outside world.

Although the exterior of the Far Eastern Palace is European-style, the interior is Japanese-style, the ground is wooden, the rooms are very empty, there are no tables and chairs and other furniture, only some screens, calligraphy and paintings and other decorative pieces.

Xiao Yan'er was very happy, she ran around the main hall of the palace barefoot happily to inspect, and was very satisfied with the environment of the palace.

"How? You shouldn't say it's cold now! Yang Wenli said to Xiao Yan'er with a smile.

"Humph! Wasn't it cold in a tent before? Did I mean to say cold? As it should be, does the royal family of our Far Eastern Kingdom still live in tents like words? Xiao Yan'er didn't give him a good face, she asked a series of rhetorical questions, and Yang Wenli was speechless.

"You're going to give me time! It is easy to build a house in a few days, but if you want to build it, it is difficult to get floor heating, you see! If I spend more time, won't the palace be perfect? We're going to live here for more than 10 years, so we can't be sloppy. Yang Wenli replied with a change of law.

"Alright! I'm happy with the house, I won't say much about you. Xiao Yan'er waved her hand and said generously.

At the same time, government departments also moved into the two auxiliary halls of the palace. According to Chinese tradition, the parliament occupies the building on the left and the government occupies the building on the right, and the two departments do not need so many rooms, and the rest is temporarily used for the courts, the tax department, the Independent Commission Against Corruption, and the military.

In the future, each unit will definitely have its own independent building, but at this stage, the scale of the Far Eastern Kingdom is not large, and the various government departments are not large, and there are only more than 100 people in total.

……

The great changes that have taken place in the Far Eastern Kingdom are unknown to the outside world, after all, Ezo Island is no different from a desert island in the eyes of outsiders, and the Ainu people are extremely barbaric, and ordinary Japanese do not dare to land on the island casually.

However, there are always exceptions, and as mentioned earlier, the Matsumae Domain was one of the few daimyo in Japan that did not have a stone high, and they did not rely on farming, but on monopolizing the fur business of the Ainu people on Ezo Island, and the only major gold mine on the island.

Not to mention the gold mine, what it produces is money, not commodities, but the fur catch is all sold to the Japanese mainland, since the Black Armor Army landed, the Matsumae family has not sold fur fish and other local products to Japan, which can be anxious for his business partners, they are about to run out of stock, but the Matsumae family has not heard from him, so one of the businessmen named Takeda Taro decided to go to Fukuyama Castle in person to see if it is really out of stock, or the Matsumae family is looking for another partner.

It's hard to say about this kind of thing, after all, the Takeda family is no longer the heyday of the Takeda Shingen era, and the Takeda family is not that important to the Matsumae family.

Of course! Taro Takeda is not the head of the Takeda family, he is just a businessman, nothing more than a businessman with a little more strength.

Takeda Taro said to go, Japan is very small, and it is only a two-day boat ride from Kanchu to Ezo Island, and when Takeda Taro arrived in the bay where Fukuyama Castle is located, he immediately noticed the abnormality.

Without it, it turned out that the flags of the Matsumae Domain were no longer flying on the docks of Fukuyama Castle, but strange rectangular flags, and Takeda Taro's heart immediately became nervous.

This can't be blamed for his overcaution, but there are hundreds of large and small countries in Japan, and there are often wars between the major names, and maybe one day a certain daimyo will be removed.

But the main thing is that the rectangular flag of the Far Eastern Kingdom is too weird, in this era, everyone is a triangular flag or a small rectangular flag in an upright shape, or a flag, such a large square flag as the Far Eastern Kingdom is unheard of.

"Welcome to Fushan City, please pay the dock docking fee of ten small sentences."

When the boat docked, there was a small official who came on board to charge, and he was very polite and had a sincere smile, so that Taro Takeda did not feel disgusted.

"What kind of dock fee do you have to pay, I am here to make a deal with your family governor, how can there be any reason to charge guests? And it's not the first time I've been to Fukuyama Castle, so I've never paid a parking fee. ”

"I'm really sorry, because you are not a citizen of my country, and my country's public facilities are not obliged to give you free use, please understand!"

"What? Non-national? Wasn't the Matsumae family under the rule of the shogunate? ”

Takeda Taro listened to the words of the little official, and was very angry, and he questioned the little official repeatedly.

"I'm sorry! We are now a kingdom in the Far East, and we no longer have anything to do with the Edo shogunate, so you are now a foreigner, and you must pay the fee strictly according to the regulations, so please cooperate. ”

The little official's temper is very good, but he still insists on his position, and his words are soft and hard, as if as long as Takeda Taro does not pay according to the rules, he will use force.

"Far Eastern Kingdoms? I'm a foreigner? It's really a big joke in the world, do you little Matsumae Domain dare to establish a country on your own? ”

Takeda Taro couldn't accept the words of the little official at once, he didn't believe that the Matsumae Domain dared to establish a country on its own, and you must know that even the shogun of Seiyi only set up a shogunate, not overthrow the emperor and stand on his own.

"I'm sorry! There is no Matsumae Domain in our country anymore, but the Matsumae family, and the Matsumae family is just a larger family in the kingdom, and they do not represent the kingdom. ”

The little official still didn't stop talking, the meaning of his words seemed to be that the Matsumae family had lost power, could it be that there was another hidden story? Taro Takeda had a full stomach for questions, but he didn't say anything more, he paid the docking fee according to the regulations, went to the dock with a full stomach, and went straight to the castle town business district, he planned to investigate it first.

Who knew that he had just come out of the dock and encountered the checkpoint and was stopped by the soldiers guarding the checkpoint.

"I'm sorry! Please register to enter our country. ”

Takeda Taro was even more puzzled in his heart, obviously he was a Japanese person, but he became a foreigner, and he couldn't even enter the castle town that he often came to?

However, with the incident of the previous officer, Takeda Taro didn't want to refute anymore, so he registered according to his words before stepping into the boundary of Fukuyama Castle with his entourage.
