Although the processing volume of various small metal parts is very large, this high-tech "small universal machining center" that even Chu Xuan has not yet figured out how it works took only ten minutes to complete all of them.

In addition to those "standard parts" that were very inconspicuous, but they were not "standard parts" that blacksmiths could easily make qualified products by hand, Chu Xuan also made a large number of weights and measures tools.

Whether it is the most basic ruler, triangle, protractor, compass, scale, measuring cup, to vernier caliper, depth ruler, height gauge, dial gauge, micrometer, pallet balance, standard meter, standard weight, standard container, etc., these are indispensable for standardized production.

Even though the processing time for these small metal items is already short compared to the processing time of large and medium-sized metal products, even so, the total one hour of prop use time is only 10 minutes after all the metal has been processed.

In the remaining 10 minutes, Chu Xuan also threw sand, salt, graphite, sulfur, messy ores and other materials into the "small universal processing center", and then manufactured many test tubes, beakers, flasks, dropper bottles, separating funnels, burettes, measuring cylinders, crucibles and other experimental utensils.

And, of course, the most important lenses, lenses that can be used to make precision microscopes and telescopes.

Because of the limitations of time and conditions, Chu Xuan can collect a small number of various metal ores, but fortunately, Echigo is rich in gold and silver, and among the associated ores of gold and silver that are of little use to the ancient people, there are many non-ferrous metals needed to make special alloys, such as tungsten, antimony, molybdenum, sulfur, bismuth, yttrium, etc., otherwise he can only make a limited number of alloys such as carbon steel and ductile iron in large quantities.

In fact, Echigo is one of the few oil and gas producing areas in the city, and there are not only oil and gas fields on land, but also on the offshore seabed near the famous Kanayama Sado Island.

However, Chu Xuan did not have so much steel for him to build a submarine drilling platform this time, so he could only put the submarine oil exploitation in Echigo very far back in the schedule, and first rely on small petrochemical equipment to refine the oil that could be exploited on the land of Echigo.

Oil is the blood of modern industry, and without oil, Chu Xuan can't even find suitable power fuel, unless he plans to burn firewood for the steam engine - the coal resources of this book are basically concentrated in Hokkaido and Kyushu.

Similarly, although the mineral resources of the company are relatively complete and are called the "metal resources standard country", nearly two-thirds of the ground of the mine is the eruption rock of the Cenozoic and the new igneous rocks, and the geological tectonic movement is fierce and there are many faults, resulting in small ore deposits, thin ore layers, and high ore impurity content, and many ores have no mining value at all under the current technical conditions.

Therefore, after refining the existing ores with a "small universal refining center" or directly making alloys, Chu Xuan did not plan to devote too much energy to the mining of minerals for the time being, he only delineated several urgently needed and valuable mineral resources according to the distribution data of the minerals he held.

At this time, the continuous mountain range of Echigo country reflects its benefits, generally speaking, more mountains are more minerals, no matter how bad it is, limestone can be mined, and the mineral resources of Echigo are basically enough to meet Chu Xuan's needs.

-- For example, copper ore can be used to make cannons and bullet casings, limestone to make cement, sulfur ore to make gunpowder and sulfuric acid, and iron sulfide to make sulfuric acid and iron and steel.

In addition, the important water systems of Echigo, such as the Agano River and the Shinano River, not only provide abundant irrigation water sources for the Echigo Plain and Takada Plain, which are important grain-producing areas in this country, but also have large hydropower reserves in the mountainous areas, and the construction of hydroelectric power plants can fully meet the power supply of Echigo for a long time to come.

It can be said that this place in Echigo is very suitable for "farming", there are rivers, grain, fisheries, minerals, and oil, all surrounded by mountains, easy to defend and difficult to attack, and the coastline is very long, which is convenient for the development of maritime trade......

"Whew~

It's finally done. ”

After the disappearance of the huge "small universal machining center", Keiji Maeda, who was almost half-naked, raised his hand and wiped a handful of sweat on his head, letting out a long breath.

Not only her, but also Kenshin-chan and the others felt that this hour was simply longer than the usual two or three hours, although their bodies did not feel tired, but this kind of fast-paced work that controlled the action time to every minute and second made these "ancient people" who had been living leisurely feel very tired.

"It's not done yet, it's just getting started."

At this time, Chu Xuan pushed down his reflective glasses expressionlessly and said lightly.

Then, he, who had just done nothing but "press the button", got busy among the processed metal parts, and it only took a few minutes to quickly assemble a very strange "machine" that was only more than one person tall.

This machine is actually a simple woodworking circular sawing machine, and the most conspicuous part is the large circular saw with serrated edges.

Its power shaft is connected to a bicycle that has been framed next to it, and it is clear that the bicycle without wheels is the low-carbon, environmentally friendly, pollution-free and renewable power source of this woodworking sawing machine.

Several "ancient" beautiful girls surrounded curiously, touching around this very luxurious "machine" made entirely of metal, and let out a "tsk" exclamation in their mouths.

"What is this? It looks a bit like a saw, but why is it round? ”

The black long straight Lori Naoe asked with some confusion as she gently flicked the circular saw blade.

Even if she is as smart as her, she has not been able to understand the mystery of the circular saw at first glance, and I have to say that this is the gap brought about by knowledge.

"This is a carpentry circular sawing machine, and then you take turns riding on it and pedaling it, and the others will work with me to see the wood open."

Chu Xuan, who was wrapping the bicycle seat with a thick cloth pad filled with straw, raised his head and replied simply.

"Oh - can this be ridden? Like riding a horse? ”

As the world's No. 1 "Wonderful", the glamorous female version of Keiji Maeda was very interested in everything new, so she jumped over one by one, and after Chu Xuan gave a simple teaching, she happily became a free power source for the woodworking circular sawing machine.

"Wowhaha...... It's so much fun!

That 'buzzing' piece of iron cut the wood so easily! ”

Keiji Maeda, a glamorous version of Keiji Maeda, turned her head to admire the scene of the fast-spinning circular saw sawing through the long piece of wood as smoothly as if a knife was cutting butter, and even the appearance of sawdust splashing on the sawdust on the sawtooth made her find it interesting.

"This is the power of 'machinery', and it can greatly improve 'production efficiency'.

But does this kind of thing that can only be used for sawing wood need to be made of so many high-grade steels?

If you want to see wood quickly, you just need to send more carpenters, isn't it the same? ”

As Echigo's "housekeeper's wife", Lori Naoe saw the power of machinery for the first time, and couldn't help but be amazed, but as a person in this era where there are many people and few things, she has not really understood the meaning of improving production efficiency and liberating a large number of laborers.

However, this is also to blame Chu Xuan, he has been busy collecting all kinds of materials during this time, and the things that need to be done by Naoe Kansue and others are basically directly ordered to do it, and rarely explain the meaning of this in detail.

In this case, Kenshin-chan and Kuro Naori Naoe, who almost didn't understand anything, believed him honestly just because Chu Xuan said that doing so would be beneficial to Echigo, and the identity of "the person favored by the gods" should be said to have played a big role.

"If the material is not up to par, at such a high speed, the saw blade can easily be blown out, just as an inferior sword can easily break out of the gap or even break.

Sending one more carpenter is equivalent to taking up one more labor, so he cannot do other work at the same time.

Although production efficiency has increased, we will only need much more labor in all aspects of the future than we do now, and we will not have enough manpower at that time.

Counting the mining of iron ore, it only takes a few months to manufacture a carpentry circular sawing machine, but it takes at least ten years for a child to grow into a qualified carpenter, and it takes much more manpower and material resources than manufacturing machinery.

Therefore, although in the short term, the cost of manufacturing machinery is much greater than the use of manpower, in the long run, machinery can greatly reduce the cost of using manpower, and the lower the cost of the manufactured product, the higher the profit that can be obtained.

Originally, a person could only create consistent profits, but now a person can create dozens or even hundreds of profits, so that our wealth will grow rapidly. ”

Taking advantage of the time to sawing wood together, Chu Xuan explained in detail the important surnames of mechanized and industrial production to Hei Changzhi Lori Naoe in a very easy-to-understand way, and by the way, Qianxin-chan.

When it came to money, both Naoe and Kenshin-chan became smarter, and they immediately understood the importance of the machine, and their eyes became sparkling when they looked at the simple carpentry circular sawing machine, as if they had seen a large piece of gold.

"That...... Excuse me...... Yes, would anyone like to do it for me......"

At this time, the glamorous version of Keiji Maeda asked weakly with a bitter face.

After the novelty of riding a bicycle that can't move at all wears off, the female version of Keiji Maeda is now forced to continue this tedious exercise as if he was being punished.

Perhaps, she will have a great psychological shadow on the sport of cycling from now on. (To be continued.) )
