Donner is in no hurry to solve the problem of magic crystal mining. Pen "Fun" Pavilion www.biquge.info

There were still almost fifty years before the magic crystal ran out, and he still had time.

Moreover, even if he desperately tried to solve this problem, it was impossible to invite Sandru to the Far North to show him and tell him: The problem has been solved for the time being, you should stay in the Magic Continent now.

Since there is no way to invite him to the scene to verify, there is no difference between true news and fake news.

As for how to spread the fake news as if it were true, Cynthia naturally had her own way, and Donner didn't need to ask.

In fact, he was also flawless, on the drawings he gave Natia, more than 200 parts had been manufactured, and Cynthia came over this time and brought the materials he needed.

The Fog City factory is ready, just waiting for him to start it.

On the last day of October, early in the morning, 400 engineering students gathered on the 37th floor of the street in Fog City.

Outside the cliffs, Ball Falls is rushing down, only two or three meters from the outer edge of the street, and the sound of the water is amazing.

More than two hundred parts, of various sizes, were neatly laid out in front of Donner, and Gernada stood beside him with his arms crossed.

Nearly a quarter of the entire street is occupied by a large amount of metal material transported from under Fog City.

"Stay safe, stay away from the cliffs. Donner reminded loudly.

At this point, the cadets were all instinctively standing away from the cliff and leaning against the inner side of the street, and Donner's fear was that they would be tempted to catch up when the machine was set up later.

Then, with Gernada's assistance, Donner methodically assembled a machine that was two meters high and two meters wide and more than three meters long - a process that took more than two hours, even with the help of Brain Logic and Gernada's efforts.

Gernada remained silent, listening to Donner's command until the machine was fully loaded, and then he muttered, "What is this big guy for?"

Donner smiled and said aloud to the students who were both curious and confused, "This is a machine used to process parts, called ...... Milling machine. Naturally, there is no ready-made word for a milling machine in this world, and Donner temporarily combined the roots of the words "manufacture" and "machine" from the Western for this new word.

In fact, in the case of desperate metals, dwarf craftsmen can process all kinds of metal materials like carpenters, and the processing accuracy is also very high (the master of dwarf craftsmen can make exquisite vernier calipers), and there is no big technical bottleneck in the manufacture of turning, milling, grinding and boring machine tools, if there was gunpowder in this world, they may have relied on guns to unify the whole territory a long time ago.

Downer suspects that it was because there were no fossil fuels in the world, and there was no suitable power source, that they did not invent the prototype of the steam engine and all kinds of machine tools.

Of course, in Fog City, this isn't a problem.

Ignoring the varying reactions of the cadets, Donner instructed Gernada to secure two heavy wedge-shaped rails into the rocks and stretch out to Ball Falls beyond the cliffs, while he himself flew into the air and hovered beyond the cliffs, driving two support rods into the rock mass and securing them underneath the rails.

As he flew off the cliff, the exclamations of the cadets suddenly drowned out the sound of the waterfall.

Gernada yelled at them, "Don't make a fuss!" to silence the commotion.

After a while, Donner flew back from the cliff, and at this point, the students' attention was all turned from the machine to him.

However, as if he didn't see it, he continued to attach a huge fan impeller to the guide rail, and then connected a pair of thick bevel gears to the fan impeller shaft.

After a series of gears had been installed, Donner checked the connections between the components, opened a bucket of pre-prepared animal fat, wiped the exposed gears with a brush dipped in oil, and poured a small half bucket into the sealed gearbox, closing the lid.

Finally, he took out a magic circle painted all black from his bosom and carefully attached it to a reserved plane above the milling cutter holder, facing the milling cutter.

Succeed with flying colors.

Donner looked at the students who still didn't know why, and reminded with a smile, "The movement can be very ......," he said, pushing the handle on the rail.

Before the fan impeller touched the Ball Falls, it was slowly rotated by the wind, and when the small half of the fan impeller came into contact with the rapidly falling water, it "exhaled" and spun rapidly, driving the pair of bevel gears to transmit power to the gearbox.

Donner fixed the slide rail, walked to the gearbox, slowly pushed down the lever, and with a harsh metal friction sound, the clutch plate locked, the gearbox began to vibrate regularly, and the familiar sound in Donner's memory sounded.

It's just this one machine, but the movement is comparable to that of the entire factory.

"After the run-in period, it will be better......" Donner said loudly to the students.

In fact, no one can understand what this means.

Everyone's attention was focused on the rapidly rotating milling cutter.

When Donner activated the cooling wind circle, fixed a piece of cast iron to the bed, and drove the milling head, the milling cutter made of desperate alloy cut a smooth and flat plane on the rough cast iron, hundreds of mouths subconsciously opened, and their eyes widened.

At this point, the first hydraulic milling machine was finally installed in Fog City and began to work.

Unsurprisingly, the milling machine caused a huge sensation in Fog City, and nearly 2,000 dwarf craftsmen were all amazed by its amazing efficiency and miraculous machining accuracy.

However, the milling machine was in service for a very short time, running smoothly for just over a month before it was scrapped. Fortunately, in just over a month, it has "born" a more outstanding descendant - Donner personally operated, using this hand-built milling machine to manufacture two hydraulic milling machines with higher precision and enough to cope with normal production activities.

At the end of December, when Richard and Lolita came up from the bottom of Foggy City and passed by Ball Falls, they saw dozens of dwarf craftsmen, under the supervision of Donner, trying to use this brand new machine.

The brothers, along with Wesley, Lucia, Una, Layla, Lolita, and others, spent New Year's Eve at Villa in the Stone, and returned to their places on the first day of the new year.

At the beginning of the new year, Downer spent another three months training the first dwarf craftsmen who could become proficient in the use of hydraulic milling machines, and by this time, the number of milling machines had reached a full eleven.

At the current density, the nearly two-kilometre-wide Boer Falls could drive about 100 hydraulic machines – and there is potential for expansion.

However, in June, when the number of various machine tools increased to 50 and the capacity of Fog City was bottlenecked, Donner's urge to continue to build machine tools was suppressed and he began to mass-produce the parts needed for the clockwork elevator with these machines.

At this time, it was exactly two years since Donner came to Fog City. (To be continued.) )
