let go of that priestess

"..."

Honglian stopped suddenly, and Jiang Lulu was caught off guard and almost bumped into her.

After stabilizing her figure, she heard Lord Honglian say with her back to her:

"You just cared about me?"

"Uh."

Looking at Lord Honglian's back, Jiang Lulu always felt that there was something abnormal today... She replied weakly: "Yes, yes."

"Oh......"

Honglian started walking again, but this time the pace slowed down a lot:

"Don't worry, I'm fine, my strength has not weakened, but has increased a lot, and it is precisely because of the increase that I stop halfway.

Last time, no matter whether you stop or not, your power will be consumed, but flying directly over will consume less power.

You may not understand it in this way. If you want to know the specifics, we will talk about it on the way. "

"Well, let's talk about it on the way."

"okay."

Chapter 200 Magic Cut

The steam engine was the greatest invention during the industrial revolution on Blue Star.

It's no wonder that later generations have raised its historical significance so high. This thing is really easy to use, and it can be applied anywhere that requires a lot of effort.

And because of its power, humans have a stronger digging ability, and they have unearthed other fossil fuels, oil and gas buried in the ground, which laid the foundation for the emergence of internal combustion engines.

Ji Cheng is well aware of how powerful these energies and motivations will be to human society.

Fortunately, almost everything here is still in the exploration and embryonic stage, and the development direction of civilization is dominated by myself.

But having said that, no matter how much you dislike steam engines, now you have to get a steam engine manufacturing workshop seriously.

Yes, it's not that using the power of dragons and magic to overcome technical problems and forcibly build a steam engine is over. That's not difficult, but subsequent mass production is difficult.

It is impossible for Ji Cheng to manufacture steam engines by hand every day.

Not to mention wasting time and magic energy, great perseverance is required, and the precision and quality of the steam engines produced each time will be uneven, posing safety hazards.

Not to mention the versatility of these steam engines when other systems are connected in the future, that will cause a lot of trouble.

So, the immediate goal is clear.

After Honglian and Jiang Lulu came out, Ji Cheng began to design various blueprints——

A drawing of the cylinder, base, piston, crank-connecting rod mechanism, slide valve steam distribution mechanism, speed regulating mechanism and flywheel of a reciprocating piston steam engine.

And after confirming that each part adopts the sand casting method of gravity casting, all the corresponding casting molds are designed.

Of course, the specific size and parameters of the latter have not yet been determined.

Because it is necessary to adjust the parameters of the steam engine to make it reach a satisfactory fuel calorific value efficiency and speed, these are easy to determine.

A few days passed in a blink of an eye, and when Ji Cheng finished drawing these blueprints, Hong Lian also came back.

The giant dragon appeared above the square, and the villagers who had gradually become accustomed to it did not exclaim in shock, but immediately notified the council hall.

The Council Hall received the news and quickly issued an order to temporarily clear the square and remind people not to enter.

Seeing that the arrangements below had been made, Honglian slowly landed on the square.

She put down the large package in one of the dragon claws, spread the other dragon claw on the ground, let Jiang Lulu come down, and then the golden light flashed and turned into a human body.

"Lulu, hand over the magic essence storage to them."

"okay."

Jiang Lulu took off the flying hood and responded.

On the way, Lord Honglian has already explained to her about her own strength, and she now understands the role of those core balls.

"Master Honglian, you can go to your lord, just leave it to me, don't worry."

"Ah."

Honglian patted Jiang Lulu's head: "Come and play with me when you have time."

"must!"

Jiang Lulu's face was slightly red, different from before departure, this time she nodded excitedly and happily, and then said:

"Master Honglian, next time I will practice my skills better and cook more of your favorite food. You, you can also look forward to it!"

"Okay~ I'll look forward to it, that's all right, go get busy, I'm leaving."

Guren chuckled, tossed her hair, hummed a little song as she walked, and wandered to Shenju.

"My friend, I'm back!"

"Oh!" Just as Ji Cheng put down the last blueprint, he looked up and saw Honglian was startled, and then laughed:

"Welcome back! How's it going? Are you tired after running around? There's nothing unexpected this time, right?"

"No, it just took a little more time. Jiang Lulu and I found all the magic element storages and brought them back."

Honglian leaned back on the seat next to her carelessly: "These magic essence storages are all full, which can replenish my magic energy consumption for more than 50 years, which is quite a lot!

In the future, you no longer have to worry about the problem of emergency magic essence!

Of course, the task with Jiang Lulu this time is not tiring, it's better to say that I have been very happy these few days, um... my dear friend, thank you! "

"Huh? Oh."

Ji Cheng blinked in response, and said, "You're welcome, as long as I can help you, don't you worry so much now?"

"It's okay, oops, don't mention it! I feel uncomfortable if you mention it...

I don't want to think about it. If I can, I naturally want you to live as long as I do. "

"..."

"Forget it, let's not talk about it, what step have you made here?"

Hong Lian calmed down her mood, changed the subject on her own initiative, sat up straight and looked at the pile of blueprints on the table while talking, and then twitched the corner of her mouth:

"Uh, don't talk about it, I don't understand if I say it, just tell me what kind of magic we will use to help you?"

"blade."

Ji Cheng said: "The magic you used in the battle in Baqie Cave, that super big red giant blade."

"Huh?...That's advanced magic."

Hong Lian didn't expect her best friend to use this, and said with a slightly embarrassed expression: "Okay, if you want to use it, best friend, advanced magic is fine."

"Uh, no, listen to me, I mean, I want to use the sharpness of that magic, just to ensure the sharpness, and don't need to release it on such a large scale."

"Oh, want a weakened version?"

"Yes, it's just a matter of precision cutting some parts, and the mana consumption should be kept at the low-level mana you can replenish."

Ji Cheng stretched out his hand and gestured, "The biggest part is about this big, and it's not easy to cut it with a giant blade."

"Ah, I understand, but it's difficult."

Honglian rubbed her chin: "You can try it. I definitely couldn't do it before, but maybe it will work now."

"Eh? How to say?"

"Part of it is because of being forced to help, and part of it is because of the training of your best friend."

Honglian shrugged her shoulders: "After coming to the world of mortals, the magic element is used to use the pick and pull soso, so it is natural to control the output of the magic element with precision and not to waste it.

The commonly used magic has basically been weakened and modified by me.

Then I met you, my best friend, and learned from you all kinds of new magic that requires abnormal control. I was baptized like hell...

Therefore, some battle magic that is not commonly used can also be tried now, not only to retain the sharpness, but also to reduce the output of magic essence, right? "

As Honglian said, a little fire flashed in her eyes, and the amount of mobilized magic essence was controlled within the scope of low-level magic.

After a while, there was no hilt, and a palm-sized red blade appeared in front of him.

Viewed from the side, the knife surface is extremely solid and stable.

"Eh?...one success!"

Honglian was stunned for a moment, then turned her head and blinked: "Uh, dear friend, I have weakened and transformed it."

"Well, it turns out that's the case, the principle is like this." Ji Cheng has been staring at the process of Honglian's casting, and now he squinted and said:

"The magic composition of the blade part is high-speed rotating back and forth, isn't it like a grinding wheel cutting or sawing machine, no wonder it is sharp.

Then, if the blade is huge, the flow of magic essence at the edge of the blade only needs to be controlled one by one, and it can be shrunk to the size of a palm, which is much finer.

The precise control you practiced can indeed be better used in this area, so it's not surprising that you succeeded once, I can reproduce it now. "

"Huh...you do it again?"

"Yes, but you still have to come."

Ji Cheng raised his head and smiled: "I use magic to waste magic energy, but now you can replenish it."

"Okay..." Honglian rolled her eyes: "What do you want to cut?"

"Let's go to the iron furnace first and then talk about it in detail."

Ji Cheng put away the blueprints on the table and said, "First, we need to create a steam engine with satisfactory performance, and what we need to cut are the various parts that make it up."

Chapter 201 The steam engine should be eliminated as soon as possible

With the furnace, iron and other necessary materials, cutting means, and technical drawings, all the prerequisites for the steam engine have been met.

It only needs to add a little effort to artificially adjust the accuracy of each component.

When a steam engine with an efficiency of about 20% was built and operated normally and safely, a month had passed.

"Okay."

The performance is equivalent to the efficiency of common steam engines in the early 20th century. Ji Cheng is satisfied, and the manufacturing time is also satisfactory.

Of course, they spent more than 1 years of steam engine invention and improvement history in one month.

If you count the appearance time of the steam ball, it will be longer, about 1900.

Hong Lian tilted her head and looked at the operating steam engine. During this period of time, she followed her best friend to participate in every step of the production, and she also had a half-knowledge of its principle.

And the more she understood, the more shocked she felt.

It's just the power to boil water, but if dozens of high-level laborers who are proficient in strengthening magic fight against it, I'm afraid they will also lose.

And this iron bump won't get tired, can work all the time, and doesn't need to consume magic essence.

What's even more outrageous is that this is only 20% efficient...

Honglian looked at it for a while, her scalp felt a little numb.

I can't express how I feel right now.

It seems to be a pity, or excitement, or... a sense of crisis.

Like guns, steam engines have a lot of potential.

They don't need to be cultivated like magic essence owners, as long as they are produced in sufficient quantities, they can be equipped with head bumps or something to turn them into weapons.

Then even dragons have to weigh it carefully when facing these mechanical monsters.

"Red lotus, red lotus?"

"what......"

Honglian came back to her senses: "My best friend, what's the matter?"

"I should ask you that."
