Is your yearning for the new world... Roland laughed silently.

Then he asked Nightingale to attract Anna.

At this time, the former will always automatically avoid it, giving the two people a space to be alone.

Anna is wearing a light blue skirt today. Under the skirt, you can see black stockings above the knees, and a pair of deer leather boots, which makes her look full of vitality. These modern style clothes are made by Roland instructed by the tailor in her spare time, and the fabric is a running water coating provided by Soloya. Not only is it light to wear, it is also very durable, and it is very suitable for her to use when processing equipment.

When Roland saw her watery eyes, he would inevitably smile.

Of course, now he no longer needs to be as honest as before.

After pulling Anna on her legs and sitting, sniffing her hair from behind, Roland first became intimate before getting to the point, "I want to develop a new source."

"Like a steam engine?" She turned her head and could see her protruding collarbone along her fair neck.

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

"Your Majesty, I'm talking about the serious business."

"Ahem, okay," he put down Anna and pulled out a stack of design drawings from the manuscript at the table. "You can take a look at this first... how much can you understand?"

"Well..." As soon as he entered the state of learning, Anna's expression would be completely immersed. Just looking at her forgot to look at her, Roland would feel inexplicably ashamed - as if he was sitting in a bright classroom with a few bright windows, sneaking at the student-teacher beside him who was writing hard.

In order to balance this mentality, he decided to make Anna bow her head to beg for mercy at night.

"I probably understand," Anna nodded after looking through the last drawing, thinking for a moment, "it is also driven by steam, but it only replaces the push piston with a windmill paddle, thus eliminating the reciprocating movement of the connecting rod. Am I right?"

"Totally correct," Roland put away his reverie and put on a serious face and replied, "Its name is a steam turbine, which is essentially still driven by high-pressure steam, but is much more efficient than a reciprocating steam engine."

This is Roland's revolutionary product for a long time.

It can be said that it is also the original intention to free the basic industry from the limitations of witches - in this way, Anna can concentrate on higher-end mechanical production.

Steam turbines are his attempts in this field.

Steam turbines are extremely widely used, and can be used as marine power or thermal power generation, especially the latter. It can be foreseen that after the fallen dragon ridge was recovered, Earl Spell had to stay in her town for a long time to handle government affairs. It was very difficult to rely on the magic of Miyue alone to maintain the night lighting of the factory area, let alone the power supply project in the residential area. Roland of course did not want to admit that this was a planning failure caused by his lack of experience. If he wanted to make up for this mistake, he could only use conventional means to generate electricity.

Due to the natural defects in the circulation principle of steam engines, the current emitted is sometimes high and sometimes low, and circuit voltage stabilization is Roland's weak knowledge, so it is a more suitable choice to use steam turbines with more stable output power and higher thermal efficiency.

"What do I want to do first?" Anna asked.

"Like the last gunboat," Roland turned to the page with the blades, "create a validation model that can be run without being too big, just about one meter. It mainly solves the angle of the blades and allows high-pressure steam to pass through each static blade grille smoothly. As long as this step is done, most of the success."

Without detailed data, should we create a useful finished product in this way?

It's just a trial and error.

Regarding the core of the steam turbine - the impeller part, Roland is not worried about the difficulty of processing. The cutting accuracy of the black fire is far superior to that of the fine processing machine tools in later generations; he does not have to worry about material strength. After all, the working temperature of the impeller is between five or six hundred degrees, and the alloy steel that Lucia found is sufficient to meet this working strength. The key is the angle of the static casing and the moving impeller. The former is like a fixed fence, adjusting the angle of the steam passing through to prevent it from rushing to the impeller, causing confusing direction or even opposite forces. In essence, it is like a comb combing the airflow.

If the model can operate normally, it will not be difficult to manufacture in an equal proportional manner.

When the processing methods and material levels are improved, it is inevitable that fruitful industrial fruits will be born.

"I understand," Anna's eyes shone with a thrilling light.

"No hurry," Roland held her hand, "You should have heard Wendy say that I decided to take the initiative to capture the devil."

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

Roland shook his head slowly.

"It's good," she leaned her head against his shoulder. "The last time I saw you injured, I almost scared me to death."

"Is that right? But I heard from Nightingale that you are the most calm one on the scene. If you hadn't dealt with it decisively, I might have really-"

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

"I understand," she let go of her palm when Roland nodded, "Anyway, what I want to say is that you must protect yourself, do you understand? If an accident occurs, use the God's Punishment Talisman immediately. Don't hesitate, even if you don't catch the devil...I will wait for you to triumph in the castle."

"Don't worry," Anna smiled, "I won't let them hurt other witches."

...

After she left, Roland remained silent for a long time before saying in a deep voice, "Are you here?"

"Of course," Nightingale's figure appeared on the desk, "but I didn't eavesdrop on what you said, and I came back only when I saw her leave."

He stood up and walked to the window, looked at the direction of the snow-capped mountains, and roughly explained the hunting plan he had imagined in his heart. "Before leaving, you have to rehearse a few times in advance to get familiar with the entire capture steps and the tasks that each other is responsible for. However, this is just a plan for the small number of pursuit devils. How to do it depends on the actual situation." He paused at this point, "If the capture operation encounters the worst situation... I mean the irreversible kind, you must bring Anna back no matter what."

Nightingale didn't answer immediately, until Roland turned to look at her, she spoke with a complicated expression, "Is this the real reason why you don't go?"

Roland did not deny it, "Otherwise you would definitely choose to save me, right?"

"…I understand," she sighed softly, "I will do my best."
