Do you yearn for a new world...... Roland laughed dumbly. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

He then had the Nightingale recruit Anna.

At this time, the former will always automatically avoid it and give the two of them space to be alone.

Anna was wearing a light blue dress today, with knee-length black stockings under the skirt and a pair of deerskin boots. These modern garments were made by Roland in his spare time, and the fabrics were coated with running water provided by Soloya, which was not only light to wear, but also very durable, perfect for her use in the processing of utensils.

When he saw her watery eyes, Roland couldn't help but smile.

Now, of course, he doesn't need to be as honest as he used to be.

Pulling Anna to her lap and sitting down, sniffing her hair from behind, Roland gave some intimacy before getting to the point, "I want to develop a new source of power." ”

"Like a steam engine?" she turned her head, and down her white neck, her protruding collarbone could be seen.

Roland couldn't help but reach out and touch it, causing the latter to let out a low chuckle.

"Your Majesty, let's get down to business. ”

"Ahem, alright," he said, putting Anna down and pulling out a stack of blueprints from the manuscript on the table, "you can take a look at this first...... How much can you understand?"

"Well......" As soon as she entered the learning state, Anna's expression would be completely immersed, and just looking at her selfless and thoughtful appearance, Roland would feel an inexplicable shame - as if he was sitting in the classroom with a bright window, peeking at the table next to him who was struggling to write.

In order to balance this mentality, he decided that he had to make Anna bow down and beg for mercy at night.

"Probably understood," Anna nodded after a moment of thought after flipping through the last drawing, "it's also steam-driven, except that the pushing piston is replaced by a windmill blade, which eliminates the reciprocating motion of the connecting rod, am I right?"

"Exactly," Roland replied, putting away his reverie and putting on a serious face, "it's called a steam turbine, and it's still essentially propelled by high-pressure steam, but it's much more efficient than a reciprocating steam engine. ”

This is exactly what Roland DG has been thinking of for a long time.

It can be said that the basic industry was freed from the constraints of witches for this purpose—so that Anna could concentrate on the production of higher-end machinery.

The steam turbine was his attempt at this field.

Steam turbines can be used for a wide range of purposes, both as marine power and for thermal power generation, especially the latter - it is foreseeable that after the reconquest of Falling Dragon Ridge, Earl Speer will have to stay in her town for a long time to attend to government affairs, and it is barely possible to maintain the night lighting of the factory area by the magic of Mystic Moon alone, let alone the electrification of the residential area. Roland, of course, did not want to admit that this was a planning failure caused by his own inexperience, and to make up for this mistake, he had to use conventional means to generate electricity.

Due to the inherent defects in the circulation principle, the current generated by the steam engine is sometimes high and sometimes low, and circuit regulation is Roland's weak knowledge, so it is more suitable to use a steam turbine with more stable output power and higher thermal efficiency.

"What should I do first?" asked Anna.

"Like the gunboat last time," Roland flipped to the page with the blades on it, "to create a working verification model, not too big, about a meter, to solve the problem of the angle of the blades, so that the high-pressure steam can pass through each static blade grille." As long as you do this step, you will be successful for the most part. ”

Without detailed data, how to make a working finished product?

It's just trial and error.

Regarding the core of the steam turbine - the impeller part, Roland did not worry about the difficulties in processing, the cutting accuracy of the black fire was far better than that of the finishing machine tools of later generations, and he did not have to worry about the strength of the material, after all, the working temperature of the impeller was between five or six hundred degrees, and the alloy steel that Lucia explored was enough to be competent for this work intensity. The key lies in the angle of the static blade grid and the moving impeller, the former is like a fixed fence, adjusting the angle of steam passing, to avoid it swarming on the impeller, resulting in chaotic direction or even opposite force, essentially like a comb combing the flocculent airflow.

If the model works properly, it will not be difficult to scale up and manufacture at equal scale.

When the level of processing means and materials is improved, it is inevitable to produce fruitful industrial fruits.

"I see," Anna's eyes sparkled with eagerness.

"Don't worry," Roland took her hand, "You've probably heard Wendy say that I decided to take the initiative to catch the devil." ”

"Well," Anna blinked, "will you follow this time?"

Roland shook his head slowly.

"That's fine," she leaned her head on his shoulder, "the last time I saw you hurt, it scared me to death." ”

"But I heard the nightingale say that you were the calmest one on the scene, and if it weren't for your decisive action, I might really—"

Halfway through speaking, his mouth was covered by Anna's soft hand, "Don't say that word casually." ”

"I see," she said after Roland nodded, and then she released her palm, "Anyway, what I want to say is that you must protect yourself, understand? If there is an accident, use the Divine Punishment Talisman immediately, and don't hesitate, even if you don't catch the devil...... I will wait for you at the castle in triumph. ”

"Don't worry," Anna laughed, "I won't let them hurt the other witches." ”

......

After she left, Roland was silent for a long time before he said in a deep voice, "Are you there?"

"Of course," said the figure of the nightingale on the desk, "but I didn't overhear what you said, and I didn't come back until she left me." ”

He stood up and walked to the window, looked in the direction of the snow-capped mountain, and roughly described the hunting plan in his mind, "Before you set off, you have to rehearse several times in advance to familiarize yourself with the whole capture process and the tasks that each other is responsible for. However, this is only a plan for a small number of devil chasers, and the specific way to do it will have to be adjusted according to the actual situation. At this point he paused, "If the arrest comes to an all-case scenario...... I mean the irreparable kind, you're going to have to bring Anna back anyway. ”

Nightingale didn't answer immediately, and it wasn't until Roland turned to look at her that she said with a complicated expression, "Is that the real reason you didn't go?"

Roland didn't deny it, "Otherwise, you'd definitely choose to save me, wouldn't you?"

“...... Understood," she sighed softly, "I'll do my best." ”

"I'm the only one you can trust but her," Roland said, patting her on the shoulder, word for word.
