After checking with Dugan about the quality of the potion at noon, Rand fed Agni lunch and gave it a bottle of purple potion.

The relationship between magic and level is not that drinking potions can be seen immediately, but that after the body is filled with magic, through continuous stimulation of magic power, the magic is used to make the magic continue to work in the body, and constantly strengthen bones, muscles and organs.

After taking the potion, Agni did feel the inexplicable energy in his body, and he felt extremely hot, and Rand also sensed the state of the fire, and directly got on the horse and rode the fire towards Rot's territory.

The fire's black hooves sparked with the ground, and as he ran, a whirlwind of flames appeared in front of him, and Rand knew that this was some kind of natural magic skill of Agni, and once Agni could use such a skill at all times, it would be a real mid-level magical beast.

In order to be able to control the highly excited fire, Rand also released his fighting energy, allowing his fighting energy to continuously merge with the magic power emanating from the fire's body, and the fighting energy guided the magic power to make the original flame whirlwind sharper.

Maned Wolf City's magic elements are relatively abundant, and they are not as affected by turbulence as Rott City, so when a person and a horse just run out of Maned Wolf City, they feel that the mana consumed can be replenished quickly.

However, when they reached the border of the Roth Territory, the flame whirlwind could not continue, and Rand and Agni quickly felt the emptiness brought about by the exhaustion of their fighting energy/mana, and Rand could only stop the fire first, and eat and drink and replenish one person and one horse.

Fortunately, he had already arrived in the city, and Rand finally returned to Roth on the night of the 26th...

"My lord? You this diagram. "Having just returned to the castle, the barbarian blacksmith Kur Yagan was called to the lord's room by Rand, and he finally saw all the drawings of the magic boiler that Rand had envisioned.

This is a boiler converted from a salt kettle, the mouth of the pot is closed, several pipes are connected from the lid, and a relatively complex transmission part of the cylinder, piston and flywheel connecting rod are connected, the power is output by the flywheel, and the steam is discharged by the pipe.

"I've never seen such a complicated diagram, especially the part outside the iron pot," the barbarian blacksmith hesitated,

"You give me a few more days, I may need to make a few wood looks first."

"Okay, you can do several," Rand was impatient to make a magic boiler, but he also knew that this kind of thing could not be approached, and could only be gnawed by the technicians.

"Let me explain to you, this pot boils water, and the steam comes out of this jar and sends it here." Rand patiently explained his drawings to Kuryagan, pointing out the operating principle and structure of each part, and the more Kuryagan listened, the more ugly his face became.

"My lord, you need iron pipes for all these pipes on your drawings, right? Do we have any of that now? ”

"If there are only a few units, I can buy them from Wangdu, you don't have to worry about this, in addition, I have asked Dugan of Wangdu to find a way to make these more complicated parts, and it is estimated that there will be results in two days." Rand, who had graduated from engineering, knew that he had encountered a complex project, so he first disassembled it into several pairs of simple sub-projects and outsourced some of them.

After all, bread makers don't need to learn how to grow wheat.

"My lord, I have a question," Kuryakan looked at Rand with some hesitation, and thought for a moment before speaking,

"Isn't there magic in our Night Qi City? In addition, there are six mages in our territory now, why do you want to do this? ”

"Because it's the spark of industrialization," Rand smiled, leaving him with an inexplicable answer.

Now that he has the magic workshops of the girls, Rand feels that the industries he envisions for his territory can gradually become a reality, but if he wants these industries to change from handicrafts to light industry, the most important thing is to solve the problem of power.

The power Rand chose was the steam engine. Not only can the steam boiler produce power, its by-product steam is also very important for the textile industry, and Rand has mastered the coal mine, and the original salt mine is equipped with a large number of boiling salt cauldrons, which can also be directly converted into boilers.

Ever since he made the plan in Night Qi City, Rand has been thinking about how to restore Night Qi City to its former glory, and the only way he can think of is to make good use of the minerals on the Galloping Horse Plain to restore its former industrial capacity.

It is not a quick step to large-scale production of alchemy products, but from large-scale farming, food processing, mining, light industry, to the resumption of metal smelting, and finally to the alchemy products.

"In any case, the spark of industrialization has been ignited!" Looking out the window at the sparkling bonfire, Rand muttered to himself.

。。

"You've got a new magic elf?" In the evening, Rand had another video call with the salt mine, and Wendy and Lili's construction in the salt mine was already in the end.

"Yes, I'll show you later, how are you doing over there?" Rand was concerned about the salt mines.

"Very well, Pete has already set off with a group of pack beasts, they have taken all the salt, the junior knight Jonah is in charge of the coal mines, they will mine for a few more days, and send the coal you want to the night unicorn city in a carriage."

"Okay, maybe there are some here at Roth Castle, if there are not enough people, I'll ask Nightqi City to send another group of people over to be responsible for transportation" Rand mentally calculated the fuel needed for the boiler, the steam engine and coal were almost bound together, and the salt mine itself also needed coal as fuel for boiling salt.

"My lord, coal mining is much slower than salt mining here," Wendy reminded Rand.

"And there is still standing water deep in some coal mines." Rand silently wrote down the problems faced by the coal mine, and mentally calculated adding a steam engine to the coal mine.

"Ben, I've bought another earth goblin now, do I need to send it to you too?" Rand then showed off the three magic goblins he had just bought

"No need, there will be an impact between the two elves." Ben Kaul interjected at this point,

"For ordinary magic elves, two elves who are too close together will affect each other's spell casting." Only after breaking through to the big goblin, not only can the big goblin communicate with ordinary people, but the big goblin can also serve as a bridge for the little goblins of the same attribute, and the big and small goblins can cooperate with each other.

I couldn't help but substitute into the teacher's mode, what magic goblins interact with each other, the effect of the abundant magic environment on goblins, and what flame goblins are born in volcanoes, earth goblins are born in the leylines, and water systems are born in lakes and rivers.

。 Listening to Ben Kaul's lecture, Rand seemed to have completed some knowledge of magic goblins, but Albert, Grua and Ben Kaul, each of them brought a small piece of magic goblin knowledge to Rand, which could only be connected in general.

The only thing that is certain is that Rand should acquire the elemental elves for a long time, after all, the flame elves are very good combustion processing equipment, which can improve the combustion efficiency, the rock elves are the infrastructure foundation, and the water elves can control the river network, which are extremely powerful productivity tools.

The role of the elemental elves was obviously not recognized and developed by the nobles, and Rand could use this cognitive gap to save some elemental elves first.
