Things are not going well.

But it's not that the dwarves don't work hard, it's that their industrial level is too bad.

Not to mention the large size of the large parts, small objects such as screws, at the level of the dwarves, can not reach the standard size required by Zhou Dong, because they do not have enough high-precision machine tools...... Naturally, it is impossible to expect a group of dwarves living in a medieval world to be able to build precision machine tools capable of mass-producing high-precision mechanical parts.

As for the CNC? The rules of electronic computing in this world seem to be blocked at present, which is something that even Zhou Dong can't make, so don't expect dwarves.

Perhaps in the future, it is possible to use magic to create artificial intelligence-like products, and then fuse them on mechanical products to achieve the effect of intelligent computers.

But now, it's not possible.

The talent points of these dwarves are still added to the iron, even some of the unique dwarves have also been involved in muskets, but the production of muskets is also made by self-employed people who polish them slowly and for a long time, rather than by high-precision machine tools that can be adjusted at least 0.005 mm/5 microns with arbitrary accuracy that Zhou Dong needs.

The submarine is moving directly in the seawater, and once it is under sail, think about if a screw expands and breaks or suddenly loosens, and then ...... There is no then.

Now the parts in the tiny size cannot meet Zhou Dong's requirements for the time being, so the previously assembled submarine skeleton can only be a large model toy.

It's been two months, and now Zhou Dong's mood is disappointed, although this situation was something he had foreseen long before the plan began.

This problem had been a symptom a month ago, and half a month ago it was proposed by the dwarves that it was difficult to complete, and then they have been working hard until now, and they have not been able to make a large number of qualified products, only a few less than five percent of the total demand.

If it is an artificial water mill, the dwarves can build a qualified submarine in a few years, after all, this is a magical world, not like the original world, the distorted results caused by some unreasonable phenomena in the original world, in this world, magic is used to operate under reasonable rules.

This is the reason why Zhou Dong foresaw it and still wanted to give it a try, he wanted to see if the dwarves could use some of the rule power of this world that was different from the original world to find another shortcut to complete the task.

Now it seems that this is still a failure.

It is still too difficult to reach the sky in one step, and at present, we still have to start from basic industry step by step.

The only thing that can manufacture high-precision machinery is high-precision machinery.

In the same way, if you want to build a submarine, you must first create a high-precision machine tool with an overall value that is not less than that of a submarine, or it is more difficult...... A whole powerful industrial production line.

"Let's go, it's time for us to get out of here and go to Ascatila."

Zhou Dong didn't hesitate, greeted Liya and Jane, and the three of them began to pack their luggage.

At the same time, the dwarves didn't know that they had been abandoned from the core race in Zhou Dong's heart.

The dwarves are too industrious, and that's not a good thing.

Laziness is the motivation to invent more convenient and fast inventions.

Therefore, the dwarves are suitable for those mechanical mechanics, and with their physical fitness, it is also a good choice to train into warriors, but it is impossible to become the core race of Zhou Dong's ideals.

Before leaving, Zhou Dong left behind the manufacturing process drawings for making precision machine tools, as long as there is detailed graphic guidance, these dwarves are still very qualified assembly line workers.

It does not need to reach the micron level, as long as it reaches the silk meter level, which is almost the diameter accuracy level of a human hair, although it is still a low-precision machine tool, but in fact, it is possible to use low-precision machine tools to produce high-precision products, but the operator needs to have rich experience and ability.

For example, if the thread required to be one micron in length, if it is purely manual, I am afraid that the entire Faren Continent will not be able to find such talents.

However, if there is a precision machine tool at the nanometer level, it is equivalent to reducing the huge difficulty of the original adjustment range of one to n to one to one hundred difficulties, and when using the machine tool, theoretically only 99 times at most, it will be possible to adjust the required micron results.

Although Zhou Dong felt that this was still very painful, it was at least within the acceptable range of egg pain.

After all, scrapped products can also be recast for recycling.

……

Askatra, a port city in the kingdom of Tesser.

When it comes to port cities, the first impression that comes to ordinary people's minds is, of course, the large cargo ships moored at the edge of the wharf, as well as the wharf porters who shout and shout from the land to the ship in a line.

Just as Zhou Dong and Leah and Jane saw now, it was summer, and the dock was full of boats and goods.

When they came to the city last night, Leah and Jane had freshened up, and today they both appeared in new guises.

Zhou Dong is now wearing a blue and black background with brilliant gold edges, and a tall and straight figure, which makes the whole person majestic and extraordinary, making people feel that he is a big man at a glance.

What made the eyes of the merchants and workers on the dock shine and couldn't be removed was a moon elf with a delicate and beautiful face on his left, a white skin with a slight blue cream, a simple moon-white long skirt and a blue diamond pendant around her neck, which made her full of elegance and beauty, if it was at night, she was completely a moonlight fairy.

Riya, who just dressed up slightly and no longer dressed up as an adventurer, regained her stunning beauty and demeanor that suited her noble status.

As for Jane, who is sitting on Zhou Dong's right, she is wearing a short skirt and stockings in bright yellow and cheerful colors, after some careful dressing, with a cute round face, it also gives people a sweet feeling like the girl next door who is in love for the first time.

Moreover, the three of them came to this dock in a carriage at this time, and on the front and back of the carriage, on the left and right, there were two tall knights wearing full body armor, if they got close, they would smell a strong non-human smell, and some experienced adventurers would instantly judge that the owners of these knights' armor were not human.

"Look at this formation, it's really amazing! It can't be the prince of a certain principality, right? ”

"I've been working in this dock for more than 20 years, and I've seen a lot of elves, and a lot of them are good-looking, but it's the first time I've seen such a beautiful one!"

"John, collect your saliva and eyes, look at the knight guards, don't get into trouble."
