The machinery that stood quietly in the room had been activated, and there was still a surplus of energy, which was the unused power storage tube, another high-tech from Avalon. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info It was invented around 436 in the Imperial Calendar, but by the time it was actually spread throughout the Empire, and then used in various industries and regions, it was already around 580 years ago.

Although there is a gap of more than 100 years, and the technology of the Hui tube has long been complete. But as the ultimate example of electricity, the Empire lacked not the technology, but the resources needed to make it—a mineral scientifically known as white limestone.

How old it has been since the discovery of the limestone may not be known. In short, as early as the time of the kingdom of Mano, there are detailed records about it:

In 1690, mineralogists discovered a new ore during an expedition into a tunnel deep underground. Its structural composition is very peculiar, completely different from all the mineral structures found at that time. They are self-contained, soft in texture, much like the fossilized flesh of a certain creature, but after various subsequent tests and experiments, this gray-white ore is only a very special ore, not a biological fossil.

Long after the discovery of white limestone, no one knew what it did and what it did. Mineralogy and geologists at the time only recorded it as a simple mineral, and never said anything about it.

Then the time entered the period of the transformation of the kingdom of Mano into the empire of St. Dorag, and the scientists of that era discovered the amazing power hidden in the white limestone. When it came into contact with a large amount of water, it produced an electrical discharge phenomenon that surprised everyone at the time. According to preliminary estimates, one standard unit of limestone, after a violent reaction with water, produced enough electricity to be used by all the people in a city for an unlimited period of one or two years. At that time, the newly established Avalon institution had already begun to study this emerging energy source.

By the year 206 of the Holy Calendar, the empire had already ended the "Inheritance War" and was in a state of slowly cultivating and strengthening its own strength. The first generation of research to put white limestone into full use was also completed during that period, that is, the prototype of the current "Hui Tube", an unusually large power generation device. At the same time, the industrially developed regions of the empire began to use this energy source. But the extraction of limestone is as difficult as it is to resist extreme climates, and it has been a long time since the spread of white limestone.

And even in an age like this, in the vast expanse of the empire, development is completely polarized. When the Manoma region has completely bid farewell to the energy related to black coal, the small frontier town where Kasia came out still uses coal mines as the main energy power, and most of the lamps there are still gas lamps, and the use of electricity is always only an auxiliary role, and most of them are labeled as nobles.

Kasia looked at the cold light around her, shook her head and sighed, and her footsteps were already on the edge of another machine in the room, where all the energy came from. Through the thick protective glass embedded in the machine, five glass tubes can be seen evenly spaced inside.

This is the glow tube, and it is also the last model popularized in industry - green light, which is positioned the same as the zero-type differential machine. However, after the zero-type differential machine, there is an analysis machine with more powerful computing power, and what is after the green light model, there is no book about it.

"It's something that's been regulated by the Empire again. Kasia looked closely at the glow tubes in front of her, which had slowly faded to grayish-white, and said that they were only the thickness of an adult's big finger and no more than ten centimeters tall. However, as the last model of the glow tube on the surface, the power stored in it is dozens of times that of the first generation of "glow tube". At full power, they are fluorescent-like green, and then as the power inside is lost, the color begins to fade and turn white. Eventually, when the electricity is completely exhausted, it turns black like coal, as if it has returned to its origins.

On the glow tube in front of him, although the color is close to gray, the electricity stored in it must be enough. This is a white limestone mining place, a treasure in "urban legends", that is, these white limestone mines.

Following his memory, he turned on all the familiar lights one by one, and only then did Kasia leave when the data on the combined machine that monitored the steam furnace began to change.

By the time they returned to the main hall, Kara and the others had searched several rooms with the light turned on by Kasia. They found a number of maps in the guard room, with the most detailed descriptions of the Seventh Pillar and a general description of the upside-down spider building on the Sky Dome.

"Mr. Kasia, these lights have been of great help. Gustin watched as Kasia walked over, nodded, and shook the map in his hand to give Kasia a copy.

"Luckily, we have enough energy left, enough to start the steam furnace, to give us the basic power for the lift. Kasia took the map and said, "The pillars are separate from the power of the mining spiders, although the differentials here are also subordinate to the differentials array in the spider itself, and can be controlled by them. But we don't have to worry too much, Nolida certainly doesn't have a combination password card on hand, and it's completely impossible to fully activate the differential array there. At most, he could only crack a small part of it, just like the seventh pillar, he could barely use the lighting system and transmission mechanism inside, and it didn't affect us very much. ”

"That's good news. "Mr. Cassia, can you answer me a question?"

"Yes. "Kasia knew what he wanted to ask.

"You're still a programmer?"

"Of course not, the difference machine that can start the management pillar is based on the experience learned in the steam factory before. If there is no programmer to crack it, the corresponding password card is required to start the differential machine, and some of them involve secrets, or important places, and will be combined password cards, which is for sure. ”

Several people nodded, and they were also very interested in how Kasia turned on the difference machine. For those who are not programmers, the combination of gears and shafts of the differential machine is another world for them.

"In a steam plant, the differential machine manages the power transmission and output of all the machinery. If something happens, the power of the differential machine is also needed to help eliminate it. Sometimes, however, the Differential is locked with a passcard that you must have in order to use it. But what should you do when you encounter a dangerous accident and you don't have a PIN card?"

"Correspondingly, there will definitely be a specific plan to deal with this situation. "So Mr. Kasia took advantage of this contingency and activated the Difference Machine." ”

Leigh's instincts and opinions have always been accurate.

"Yes, that's probably what Mr. Hill meant. Kasia nodded. "In the steam factory, the difference machines that are bought will be cracked by professional programmers in advance. And the people in the factory will take the initiative to ask the differential machine company to install a backdoor for them as a contingency plan to prevent encountering the situation mentioned above. And this backdoor is to act as a password card and forcibly start the differential machine. ”

Kara and the others nodded, with a look of understanding on their faces, and then didn't ask anything more.

At this time, the sound of rapid flow of air also sounded in the ceiling above him. It was inside the hollow brass pipe, and the scorching steam filled the rushing sound, and everything was ready to fall into place at this time. The other pillars were also lit up in the following time. Like a glow stick in the dark, the pillar leads to the Steel Spider building in the sky.

Kasia and the others deliberately leaked this information about the Difference Machine, and also told them that there might be a map in the security room. Now everyone is still allies, and Kasia's target is only Norida, and the rest of them can be their friends as long as they don't hinder them.

At the same time, when all the lights inside the eight pillars are turned on, inside the spider building, which is the room on the edge of the steam drill bit in the very center, the sign in the upper left corner tells us that this is the main control room, which is the room where the differential machine array is located.

With a glass of red wine in his hand, Florus took a sip on his lips as he looked out through the glass window at the edge of the large room, his eyes and the goblet containing a small half glass of red wine reflected the shining shadows of the pillars that lit up outside the window. There was a sad look on his face.

"Don't worry, Mr. Floss, their actions are still exactly what we planned. Someone behind Floss spoke, and his voice felt rough, "Although this plan was a few days in advance. ”
