At the beginning of February, Donner's studio in the stone villa has been turned into a small processing workshop. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The pieces that were brought in from the Fog City factory were built like Donner, first with a small steam engine, then with a simple but well-made forging machine.

A one-meter-square, one-millimeter-thick steel plate weighing more than a hundred kilograms of the Secret Realm Xuangang was painted with an almost complete (with a circular blank in the middle) seventh-level magic crossbow circle painted by Donna with antiseptics, and after being coated with antiseptic on the back, it was soaked in sour wormwood juice for a full ten days.

In ten days, the acid wormwood juice corroded a thin layer of about half a millimeter of the Xuangang that had not been coated with antiseptics, and the embossed mark of the seventh-level magic crossbow circle was exposed on the Xuangang plate.

Ten days later, Donner embossed the black steel plate, which was less than 100 kilograms, upward, and laid it flat under the forging machine where the workpiece should have been mounted, and fixed it properly.

During the whole operation of him, there were only two audiences, Una and Layla.

"Look at the point, the next work will be handed over to you later. Donner said as he put on his gloves and pulled one out of the Demon King's light iron sheet with Mithril stacked on the side of the studio and spread it on the black steel emboss.

He then nodded to Una, who excitedly activated the flame circle beneath the steam engine's combustion chamber.

The flame heated the water vapor, driving the camshaft to start rotating, Donner pushed the lever of the forging machine's gearbox, and the one-meter-square flat steel ingot on the head of the forging machine slowly lifted, and after rising to a height of nearly one meter, it fell with a bang, scaring the two girls into screams.

Donner shook his head with a smile, and when the head of the forging machine rose to half a meter, he pulled down the lever, disconnected the gearbox, and asked Una to extinguish the flame circle under the combustion chamber of the steam engine.

It wasn't until the steam engine stopped running that he used his hands wearing cotton gloves to remove the Demon King's light iron sheet just now, flip it up and down, and put it on the operating table aside.

Compared to the heavy Secret Realm Dark Steel, the Demon King Light Iron is as light as nothing, even Layla can easily move it, however, in order to prevent being scratched by the steel plate, it must be operated with gloves - the high-level has good resistance to fire and low temperatures, but is still afraid of physical damage.

Una and Layla huddled around Donner, looking at the thin plate with a clear magic array embossed on it, and let out a heartfelt amazement. Although I had seen Donner demonstrate the principle as early as a month ago, I was still surprised to see such a large steel plate engraved with the magic array pattern.

"Young master, let's do the rest!" Layla was already eager to try.

"Alright, come on!" Donner smiled and stepped back a few steps to stand behind them.

Una and Layla picked up a brush half a foot wide, dipped it in magic gold, and each began to paint the thin plate from one side, and in a short time, the entire steel plate was coated with green and shining wind magic gold. Because this color is somewhat like rusty copper, it is called spiritual copper.

Then, following Donner's example, Una used a metal scraper to carefully scrape off the spirit copper that was still in a liquid state on the surface of the sheet.

It wasn't until this step was done that the two girls looked back at Donner.

"The primitives made in this way have no drawing process, and there are no magic fluctuations, so the magic gold is still liquid, and if you move the steel plate at this time, the magic gold in the groove will flow out. Donner explained, picking up a paintbrush from the side of the console, dipping it in magic gold, and drawing a complete element along the end of the magic line in the circular blank space in the magic circle.

At this time, a clear wave of magic flashed across the circle, like a breeze blowing on the water, but this breeze did not produce ripples, but solidified the magic gold on the entire circle, and even the color became dark green.

Anyone who has ever drawn a magic circle knows that regardless of whether the circle is drawn successfully or not, the magic gold has lost its vitality and can no longer be used.

"Young Master, we haven't checked the quality of this magic circle yet!" Layla suddenly remembered her duty and said anxiously.

"It doesn't matter, the lines are all there, even if there are gaps, you can make up for them. Donner smiled, just like when drawing a circle by hand, if there is a mistake or omission, you can erase the element and redraw it at any time, as long as you act fast enough to remedy it before the magic gold corrodes into the inside of the substrate.

"Then we'll check it now!" Una quickly picked up the drawing pen, leaned over to the thin board, and gently stroked the surface of the magic array, looking at it inch by inch.

Layla pulled out a delicate precision scraper, her eyes following Una's fingers.

Donner clasped his arms to his chest, and after only looking at it for a second, he knew that there was a mistake in the circle, and he just waited to see if the two girls could find out.

In fact, without the help of the brain, many parameters of this marking machine would have to be tried and tested to finalize the final shape. Throughout the process of preparing for the construction of the Fog City factory, Zhibrain has saved Downer several years of time.

Donner knew that this should be one of the equipment provided by the Bright God civilization when it sent earthlings to this planet to fight, and maybe one day, when the civilization of this planet develops to a certain extent, he can reverse engineer this biochip to obtain some technology from the super civilization.

It's like this magic array in front of you is a reverse engineering of the technology of the factory owner's civilization.

As Donner was thinking this, he suddenly heard Una shout, "There's a little defect here......

He walked a few steps, and saw that the piece Una was repairing was the same one he had already seen.

After Una and Layla had repeatedly confirmed that the circle was correct, Donner pulled the clockwork drill on the workbench and drilled and tapped the wire in the center of the circle. At this point, a nearly complete seventh-level magic circle was finally made, and only the "key" remained.

For the next ten days, Donner remained in the Stone Villa, first teaching Una and Layla how to safely use tools such as forging machines and bench drills, and supervising them to make thin plate circles from beginning to end.

Ten days later, most of the more than 100 light iron sheets stored in the studio have been consumed, and the original etched black steel mold is still unscathed. Donner estimated that such a mold would probably be able to engrave thousands of light iron circles. According to his installation plan, by the time this Xuangang mold is used up, this seventh-level magic crossbow array should have been eliminated.

At the beginning of March, under the guidance of Donner, Una finally made the first magic crossbow "key", and Layla was only four days late and successfully trial-made.

Compared to the perverted precision that Donner pursued when making magic wands, the "key" of the magic crossbow is more than an order of magnitude simpler, and once Una and Layla get their hands on it, they can mass-produce one in seven days, and when they become proficient, this speed can at least double.

And the efficiency of the engraving circle is much higher than this.

At this point, Fog City finally has two factories, a machine factory dominated by dwarven craftsmen, and a magic circle factory hidden in a stone villa.
