On the 29th, Kuryagan, Jonny and others finally worked out a set of handmade steam cylinders, as well as matching pistons, reversing brakes, connecting rods, flywheels, etc.

Hearing the good news, Rand ran to the magic workshop, even though the steam boiler was still being made, Rand still wanted to test the completion of the cylinder.

In order for the cylinder to run, it was necessary to smoothly deliver gas to the cylinder, but there was no wind mage or air supply device in the camp, so Rand simply brought the flames.

The experiment was very rough and simple, the fire was tied to the courtyard, and the experiment required her to release a nearly whirlwind of air directly into the steam inlet about 20 cm diameter on the cylinder 15 meters away, if the breath reached the piston and could turn the flywheel, it meant that the cylinder was basically successful.

Let a magical beast do this kind of precise experiment, it can be said that the orc is silent when he listens, the tower of purity is in tears, and Rand himself is not very reliable.

"Agni, it's not the Wind Blade, don't break this cylinder" In the workshop, Rand rode on a horse, trying to channel the wind magic of Agni with his fighting spirit. Once he sensed that the force of the wind blade activated by the fire was too great, Rand had to use his own fighting energy to guide it away from the cylinder.

"Bell~Bell" Several wind blades hit the wall built by the earth goblins, sending out a huge vibration.

"It's really easy to sharpen the edges, I'll let you go to the flat before you paint the wall next time" Looking at the wind blade inspired by the flames, Rand felt like he was controlling the bucket of an excavator to lift a bottle and pour water into a cup.

"My lord," Kaye ran over, "can you let me talk to her?" ”

I saw the centaur girl walking to the side of the fire, her hands made a prayer state, her eyes drooped, silently reciting the prayer, and the monster horse, who was still a little restless just now, put the huge horse's head to the girl's head in understanding.

"It's... Jonny and the others looked at it in shock, but they were thinking in their hearts, these are all four hooves, can they really have a common language?

About 10 minutes later, the fire really inspired a relatively weak wind blade, the wind weakened after leaving 5 meters, and then the second wind blade hit, after the two winds staggered to form a strange air flow, after a few seconds the air ** did enter the steam inlet, the magic of the wind drove the air into the cylinder, pushing the piston, the piston drove the connecting rod to rotate the flywheel, the connecting rod and the slide valve drove the reversing valve in the cylinder, so that the air can drive the piston to do reciprocating motion.

The magic of the "Oooo

"Your Excellency?" Sophia looked at the wheel, "If you just need this wheel to turn, why don't you use the wind to push the windmill?" Then he drew on a piece of paper, "You can draw some wind runes on the blades, which Gandalf taught you to increase the speed of the wind." ”

"Your windmill is a bit of a problem, if the shaft in the middle is not strong enough, it will soon be useless," Rand looked at the girl and brought a charcoal pen, "You can also remove the shaft and make a shaftless fan." Rand said as he painted, "You can also make this kind of spiral fan, so that the contact area between the wind and the fan is larger." ”

"My lord, these?" Sophia, Firefly, Jonny, and even Kaye all leaned over and looked at Rand's drawings.

"You can try all of these, my idea is very simple, what I need is power, it can be boilers to boil water, coal can be converted into power, it can be magic into power" For Rand, coal mining is a ready-made resource, and it is not necessary to use it in vain. But if Sophia was inspired to develop magic to transform power, or to make power more efficient, that would be great.

"Let's give it a try, but I'm afraid there are a lot of parts that you need to buy." Jonny looked embarrassed.

"It's okay, you tell me this afternoon, what else do you need to buy, I'll let Dugan buy it."

In the afternoon, Rand spoke to Dugan, who reported that there were some factories in the imperial capital that had similar needs to Rand, and he had asked Master John to go to the imperial capital to buy them.

"John asks if you want to buy small and medium-sized connecting rods and cranks" Dugan was not familiar with industrial vocabulary, but Rand understood, "John said that some factories in the imperial capital have this kind of thing, and if you don't mind scrapping parts, it should be quite cheap"

Immediately afterwards, Dugan also took the note that John wrote to him, explaining that the so-called scrapped parts were because the magic runes on the parts were scrapped, not because there was a problem with the structure of the workpiece. Once the runes fail and the magical properties disappear, the price of the artifact drops by an order of magnitude.

"If you can, help me buy some bearings and fans," in line with the principle of making the best use of ready-made human industrial achievements, Rand put forward his own needs, and also specially drew a sample drawing, so that Dugan could draw it in the same way, "Did John say that such parts are used in what equipment in the factory?" ”

"He seems to have mentioned a rune stamping or something."

Rand had a new understanding of the Empire's industry, and commissioned Master John to buy as many scrapped parts as possible.

In the evening, Rand contacted Ben Kaul to find out which equipment would be used in the imperial capital.

"Functionally speaking, your device is not rare, it will be used in many places, you should have done magic ascension and lowering in Dragon's Tooth City, and that device made use of a similar device." Ben Kaul kept recalling.

"Yes, but I don't have a magic furnace in my castle, and there are no leylines under my castle, I want to use coal as an energy source"

"It's not impossible, as far as I know, some arsenals in the imperial capital have made some machinery for stamping and engraving runes in recent years, and it is estimated that some of them are similar to what you need."

"In addition, the Imperial Salt and Iron Division has a very similar equipment, but they are not connecting rods in the gearbox, but a metal with repulsive effect runes drawn, but such a transmission box is estimated to not be sold to you."

"Tell me what I can buy," Rand didn't think that the equipment of the Salt and Iron Division could be bought

"There used to be a more primitive one, which has been out of use for hundreds of years, but... Wendy, why don't you take someone to the caves tomorrow to look for them, maybe there will be more," Ben instructed the girl beside him. ”

Of course, Rand couldn't just wait for news from Wangdu, he asked Kur Yagan to manufacture 4 or 5 sets in small batches according to the connecting rod and cylinder scheme that had been explored.

After another 3 days, Kuryagan finally put an iron lid on the medium salt pot with a water injection port and a steam outlet, and after Kaye drew runes, it could form a steam boiler with the salt pot, and after assembling it with a set of cylinders, the output power could drive a water wheel to lift the water to a height of 2-3 floors.

The heating part of the steam oven is fueled by the flame fairy to heat the rune plate, and if you simply burn coal, the heating efficiency is significantly reduced.

Rand had seen the boiler room for a while in his previous life, and after the boiler was initially completed, he began to design a preheating device to use the heat of the exhaust steam to heat the water ready to enter the boiler in advance.
