After leaving Tilly for a while, Roland spent all his time on transcribing the materials.

First of all, the basic courses of each subject. The textbooks written based on memory were not complete. Now I have the opportunity to re-examine the content hidden deep in my consciousness, so I naturally have to make up for the missing parts.

Secondly, there is still a lot of gap between the use of drawings for the current equipment in Winter City and the easy to use. Using these mature designs can further improve the working efficiency of steam engines and machine tools.

Guided by the new design drawings, Anna finally completed the prototype manufacturing of the first steam turbine.

Unlike the way she accompanied the girl in her previous life, Roland rushed to the north slope backyard after receiving the news. The two sat side by side on the workbench in the yard, enjoying the behemoth together.

Its length is close to six meters, and the dense impeller is finely fitted by the shell, which looks like a huge metal drum. The external connection is a preheated boiler and a steam boiler. Under the heating of coal, the spindle is driven by high-pressure steam, which is much better than the reciprocating steam engine in terms of efficiency, noise or tremor.

As a new generation of driving force, the first aircraft will be used on sea boats to meet the thunder's adventure needs.

Unfortunately, despite its wide range of uses, it is difficult for the factory to have the ability to process steam turbines in a short period of time. In addition, Anna will soon be invested in improving the machine tool, and no second steam turbine will be released for the time being.

"How is it?" She turned her body sideways and pressed against Roland's chin, "I'm very awesome, aren't I?"

Anna is also different from most girls. When she is happiest, she is transforming the design drawings into physical objects. Whenever she completes a major project, her pleasure and satisfaction will always be hung on her face without any concealment.

It can be seen that Anna is very interested in her current life.

"Of course, second only to me," Roland smiled and wiped the stain on her cheek, smearing a light gray mark.

Every time he saw her clear and transparent lake blue eyes, he agreed to Nightingale's words and swallowed them back. Although he had made up his mind to confess to the other party, he realized how difficult it was to actually do it.

No matter what excuses you make for, you cannot reduce this heaviness.

In recent days, he has been copying books and sketches constantly, and he also wants to use his work to fill his spare time and avoid the fantasy of worrying about gains and losses.

But procrastination is also a kind of harm, especially for the expectant Nightingale.

He can't keep escaping.

As the boiler gradually cooled down and the steam turbine stopped running, Roland took a deep breath and leaned into Anna's ear and whispered, "Come to my bedroom tonight, I have something to say to you."

...

After nightfall, he sat at the desk and could hear his heart pounding.

This era is not like modern society, and no one cares about how many women the nobles have.

I'm just following my will.

No one will think it is contrary to common sense.

Reasons kept popping up in Roland's mind, and they were rejected one by one, as if two consciousnesses were fighting each other on the top of his head. He wanted to fill in the last bit of content that had not been copied, but he just held the pen and couldn't write a word for a long time.

Until the door was pushed open by Anna.

The sound of arguing above his head disappeared without a trace. He put down his quill and focused his attention on the girl.

She looked as usual, wearing loose pajamas, with some wet bangs still pressing against her forehead, and a smile was hidden in her happy expression.

For some reason, Roland suddenly recalled the scene when the other party took the initiative to wait for him at the stairs after the first evil month ended.

Anna never complains or feels wronged, she only expresses her thoughts and demands directly.

Now it's his turn.

Roland pulled her to the table and slowly spoke out what was in her heart.

The next was a long silence, which was so long that he thought Anna would turn around and leave, slowly raised her head and looked at her, but found that the expression in her eyes had not changed much.

"that's all?"

Roland was stunned, "What?"

"I kept wondering when will you tell me this," Anna sat down beside him. "I don't want you to say it so early, and I think you will say it faster, the better... I finally don't have to worry about it."

He opened his mouth wide, "Did you know it long ago..."

"I can see, especially the Nightingale's feelings for you," she said bluntly. "The later you confess, the more you care about my feelings. But I hope you can tell me your thoughts earlier, because no matter what that is, I'm willing to share it with you."

Speaking of this, Anna sighed lightly, "At first, I didn't expect to be loved by a royal noble, but later it gradually became just by your side. Since you said you wanted to marry me, my ideas have become different again, Roland, and I will not give you to anyone."

"Sorry, I..."

"You have nothing to apologize, the feelings themselves have no reason, and... you choose to tell me this at this time, which makes me very happy." She paused, "You are not from this world, are you?"

Roland's heart thumped.

"No matter whether it is a noble or not, no one should be hesitant or uneasy about such things, unless the world he lives in is very different from ours," Anna continued. "Same thing, there may be people in this world who will treat witches well, but they will not treat them as close friends. Do you remember the bet between you and me? In the book, I wrote you as a visitor to another world that is not hell or abyss, but a better place. You came with knowledge that we have never touched, and it was the god who sent you to me."

By this time, he had nothing to hide, "Although the details are different,... you guessed it right."

"I've also written in it that you'll confess the Nightingale to me," Anna chuckled softly, "It seems that at least I've guessed two things right now."

Roland discovered that Anna's intelligence was not only about learning, but also her understanding and observation skills were amazingly strong.

Before he could speak, the girl had already held up his hand and said word by word, "I can't promise you about the Nightingale, at least not now."

Roland couldn't help but be stunned. At least it doesn't work now...what does it mean? Can it be done in the future?

"I know what you are worried about, don't worry, I will have a good talk with her, go to bed early," Anna kissed him gently, "Good night, your majesty."

The door creaked and the room was closed, and the room returned to silence. Roland did not come to his senses until a long time after the other party left.
