On the fourth floor of the Salt Mine Cave, the inhabitants here are mainly the rooms of ordinary demon supporters, each room here is smaller, one usually houses 2-4 demon supporters, and two rooms are even larger, and there are large shops with more than a dozen people inside.

As he walked, Rand suddenly had the illusion of inspecting the student dormitories in the school before, and I have to say that although the conditions on this floor are not good, both the room arrangement and the space layout are very reasonable.

Considering the height of the demon bearer, the height of the entire fourth floor is about 3 meters, which is lower than the fifth and sixth floors, and each 4 rooms are very close to the layout of Rand's previous school dormitory, of course, there are basically no windows, Rand is hard to imagine, why can there be such a coincidental cave on a mountain of more than 100 meters, which is a cave, it is simply a specially excavated cave dormitory.

"It's really excavated, Lord Rand," Gandalf replied with a smile after Rand asked, "Not only the rooms you see, but also the pools in the rooms, the drains of those toilets, and the location of the rune boards have been reserved, and I have only drawn runes since I got here, and there are no new features."

"What?" Rand didn't turn around.

"You wouldn't think this salt mine was discovered and mined by barbarians, would you? The entire salt mine area has been mined for thousands of years, and the cave has been a dormitory for the miners in the salt mine for hundreds of years."

"I said, how can it be so coincidental?" Rand suddenly realized, "But no, how many magic crystals do you need to operate with these runes?" ”

"You don't need a magic crystal, do you think that the Terran demon supporters who are treated as drudgery will have their own magic crystals?" Gandalf explained, "It's normal for you not to know about the magic web, and as far as I know, even the magic school in Dragon's Tooth City doesn't teach this kind of knowledge. ”

The magic net is commonly thought of as a certain linkage between magical elements throughout the world, and the magical elements are linked to each other in air, water, and soil, forming regular fluctuations on a macroscopic scale.

Generally speaking, the fluctuation of the magic net is smooth and slow, but in the soil, as the bottom layer deepens downward, many magic elements will have different concentrations in different bottom layers, and when the bottom layer produces geological changes, it will produce a huge magic concentration difference in the same formation depth, and this concentration difference may suddenly release a large amount of magic energy, or it may slowly release a fixed and small amount of magic energy.

Magicians call this kind of terrain that can release huge magical energy called the leyline, which is often located on the terrain such as volcanoes and minerals, and the energy contained in the leyline is huge, and the formation and release of energy is remembered for 10,000 years, which can be regarded as a natural magical energy mine.

According to Gandalf, the leylines beneath the salt mines were discovered and exploited hundreds of years ago, and all the magic and alchemy devices in this cave are operated by the energy released by the leylines, which are first gathered in the heating pool of the workshop on the first floor and then distributed to the rooms on each level.

"Are there any other caves like this on this mountain?" Rand asked, he remembered that the barbarian camp in the north of the salt mine had also excavated the surrounding mountains, and he didn't know if those barbarians had a whim or continued to develop through the existing mines.

"I guess you're talking about the camp up to the north, right?" Gandalf understood Rant's thoughts: "There are caves there, I have seen them in the past, but there are no salt mines there, so they are not being used. ”

"I see" for Rand, isn't this similar to the geothermal energy of his hometown, but geothermal energy needs to be converted into mechanical energy by a boiler, and here it is directly used to use the magical energy contained in the leyline, which is indeed convenient.

"That means if you can find a large leyline, you can build a city?"

"Of course, most of the big cities are built on the leylines."

"Oh, that's it." For a moment, Rand felt that something was wrong, but as the whole team was about to go downstairs, Rand didn't continue to discuss it with Gandalf.

The third and second floors of the salt mine are the living spaces of the demonsless, and the third floor is mainly inhabited by children, skilled elders, and managers, and the number is relatively small; The second floor is labor, which is large in number.

On the second or third floor, the corridors on each floor are 4 or 5 meters high, and the living rooms are divided into two floors so that more people can live.

There are three halls on the third floor, one of which is not only large in size, but also very bright with the geological space at the top of the cave.

According to Gandalf, these halls are the children's classrooms, the administrator's meeting room, and the place where the ascetics preside over the prayers of the demonsless.

In the light-filled hall, Rand met several demons-free people who were responsible for the management of the salt mine, Monhqi, Doryaf, Mick, Jairg, etc., these demons-free Rand had seen at dinner yesterday, all of them were the demons-free who assisted Lannia in managing the salt mine, and it was these people who had managed the more than 2,000 demons-free people in the salt mine in order in the past few years.

These people are similar to the stewards in the barbarian camp that Rand met before, they are all local stewards and scholars who raided various Terran territories after the barbarians raided them, and they themselves have a deep understanding and practical experience in territory management, and they also returned to their old business after arriving at the salt mines.

Rand knew that she would immediately lead the knights out of the main camp to fight the gray geese, and in the future, all the demonsless people in the camp would still have to be supported by Corania first, and now she could not weaken Lania's authority in front of her assistants.

"Lady Lannia introduced you to me yesterday, and I will lead everyone back to the Dragon Kingdom in the future, and I will need you to help you do everything in the camp along the way." Rand had to clarify Lanya's status first.

"Don't worry, once you return to the dragon, there will be more than 3,000 lords in my territory, and a large number of talents like you are needed, as long as everyone is willing to do things honestly, I will not treat you badly."

"Yes, sir."

After the housekeepers finished speaking, Gandalf called over a few more girls.

"My lord, let me introduce you, this is Rima Camel, this is Mercy Haili, this is Ninon Via, you have already met their brothers, they are all demon lovers or knight apprentices, they were literate before they came, and they have been assisting Lannia in dealing with various accounts and paperwork in the salt mines."

"Very well, then they are still in charge of the paperwork, and you still follow Lanya.

Real Jean? You also teach them to settle accounts. ”

"Yes, my lord"
