As soon as Rand has the effort, he will think about various industries for the territory, such as wool spinning, paper, soap, brewing, fermentation, pottery making, brick burning, mushroom planting, etc., some technologies such as brewing, pottery making, brick burning, and wool spinning are the technologies that the existing lords will know, and the remaining technologies Although the lords will not, the Rand can probably recall the principles or techniques of the previous life.

The advantage of these is that as long as the process is understood, the industry can be developed without magic, and Rand hopes to be able to add magic to some process steps, simplify process steps, and improve efficiency and product quality.

For example, the magic pattern pottery jar that Rand asked the girls to make, the magic provided by the magic rune is just enough to allow the warming rune to maintain the temperature in the jar at 35-45 degrees Celsius, which is suitable for the reproduction of lactic acid bacteria.

Not only yogurt, but also koji, fermented bean curd, and in the future, compost, all of which control temperature and humidity allow different substances to slowly ferment under the action of microorganisms.

Another example is a complete set of papermaking equipment that Sophia is currently developing, including raw material powdering, cooking, rolling, and pulping; There are wool spinning equipment that Rand has been thinking about for example, similar to that of the girls.

After the breeding business gradually got on the right track, the girls' workshop became the research and development base of the territory's craft equipment, and every time Rand arrived, he would check the progress of a batch of new equipment in the workshop, and also bring some new ideas.

。。 Salt Mine, Shandong, Emergency Communication Room. Benkauer was redrawing the pattern on a magic mirror, while Wendy, not far away, was studying the circle on the wall.

"Wendy, I only have a little work left on my side, and when I communicate tonight, I shouldn't have the same unstable problem as yesterday" Ben's attention was completely focused on the magic carving knife in his hand, and he didn't have the energy to look at the girl next to him.

"If you have something to do, go ahead, there's no need to stay here with me." Just like Ben Kaul promised, as early as the daylight of the 17th, he used the magic circle in the emergency communication room to establish a magic mirror line that could connect to Roth Castle, and communicated with Jonny and other girls in Roth Castle last night, but the magic patterns on the magic mirror still need to be adjusted to keep the communication open for a long time.

"Oh, well", Wendy's hand dropped from the rune line on the wall,

"Then I'll go to a few warehouses, yesterday Jonny said they need more paper, I'll go through the old warehouses."

"Okay, you can go quickly." The mage heard the sound of the door closing, sighed silently, and in an instant, the magic carving knife in his hand flew around, and the light on the magic mirror also brightened.

Outside the communication room, the magic goblin saw Wendy coming out, and flew over with great concern, although his mouth was silent, and he was desperately gesturing with something.

Wendy gestured around the room, only to see the magic goblin shaking his head and gesturing with his hands outstretched.

Outside the cave, Pete was arranging for the knights and barbarian cavalry to pack all the salt that had not been carried before, and according to Rand's request, there was still some salt that they needed to collect on the spot.

"Leave your team to pick brine," Pete said to his team leader,

"Team 2 will follow Mage Wendy to search the warehouse, and the rest will go to the coal mine to the north, and we will stay here for 3 days at most before we return!"

"Yes!" The knights split up. In the past two days, Wendy and Ben Kaul have transformed the brine extraction device, the new brine mining device sends a slender long barrel to the rock well through a rope, and when the long barrel is filled with brine, the long barrel is pulled out of the well by pulling the pulley device next to the salt well with a horse, and there is a one-way valve at the bottom of the long barrel, which can pour out dozens of catties of brine after opening.

The brine goes directly into the bucket for transport, which is filled and pulled by a horse-drawn cart to the salt boiling workshop in the cave, without the need for manpower.

This method of brine mining was transformed by two magicians according to the ideas of Rand's hometown, and the original manpower to mine brine was too slow and too crowded.

The new plant does not require manual extraction of brine, only needs to be supervised by someone on the side. The main step in limiting salt extraction is the number of wells, and there are currently only two working wells in the entire salt mine, and while it takes time for these wells to extract brine, Pete can also arrange for personnel to test the tunnels for digging coal.

Compared to Iwai's side, the mages made minor changes to the mine, only allowing the magic elves to level the mine floor and widen and raise the mining channels.

At the end of the day's work, the Knights' Demon Enthusiasts gathered together for dinner in the cave hall, and Wendy and Ben listened to their experience of using it.

"Master Mage, can the minecart in the coal mine move on its own? It is not difficult to dig coal, but it is too hard to transport coal! ”

"Master Mage, we used to only mine salt, and our bodies were fairly clean, but this coal digging is too dirty! Take a shower and queue up! ”

"My lord, we may not have enough horses, right?" Wendy listened to these people's opinions, but in her heart she was meeting what Rand said that night,

"Brine is generally accompanied by natural gas, and if natural gas can be used as fuel, the coal used to boil salt can be saved and directly supplied to Yeqi City. If a steam engine can be developed, transportation in the mine can also be solved. ”

"What is natural gas?" Wendy frowned,

"What is a steam engine again?".

"My lord? Can you hear me? "At 9 p.m., Wendy and Bencall met as agreed.

"Of course, how about your side? It's already warmer on Roth's side, is it still snowing on your side? "The Rand in the magic mirror is very clear.

"Winter on the plains is like this, when it says snow, it snows, and we're all used to it," Wendy happily told Lante.

"How's the salt mine?"

"It's good, according to what you said, the brine mining device has been modified, and I have also strengthened the wall of the camp with the goblins, this mage said that the area should be expanded a bit, and it is best to cover the entire valley mouth, but I think the project in the salt mine valley should be completed first." Wendy answered before Ben could speak.

"Yes, Wendy learns quickly, don't worry," Ben also smiled.

"I see, you can do it according to the specific situation in the salt mine, and you can tell me with the magic mirror at any time. Also, tell Pete that he must arrive at Night Kirk City at the end of the month. "Rand in the Magic Mirror is very concerned about the transportation of table salt.

"Got it, I'll tell him about it" Wendy was about to run out, and there was nothing more to say, so she said goodbye to Rand, and the magic mirror turned into a normal mirror again, and the video communication was interrupted.

Wendy arrived at the door, but when she turned around, she saw that the mage was still holding the magic mirror in his hand, and he had no intention of leaving.

"Teacher, are you okay?"

"Yes, I want to change the circle here again, it can reduce the consumption of mana," the mage pointed to one of the circles in the magic mirror.

"Okay, then I'll go find Pete first." The girl smiled and left.
