Dusand spent a whole afternoon, plus two cups of black tea, a bouquet of flowers and six pieces of cream cake, to coax Rowling again. When he saw the smile of Rowling again, Dusand felt a layer of sweat appearing behind him.

People in their thirties still have to do such things... Dusander felt a little sad. But he quickly regained his energy - in fact, this kind of Lorraine was a bit human. This was better than the doll lady who was not invisible to her emotions.

"Does the improvements you said today really work?" Eating the cream cake with Dusander's quota for the next week, Lorene decided to care about her fiancé's academic development. "I think Mr. Polina seems very excited."

“All I have come up with is just some unverified ideas and suggestions,” Dusand said in a habitual manner. “Luckily, it seems that Mr. Polina is indeed inspired.”

"I spent a day today, but I didn't write anything in my laptop," Lorraine muttered, "It's not worth it."

Lorraine had something in her words, and Dusander smiled bitterly and said, "Why... I will teach you the basics? Let's start with mathematics."

Dusander himself hasn't learned much about the imperial laws and regulations, so he still has to teach people.

But he is quite good at math.

The empire is the same as the mathematical system of the earth. It is both decimal and uses almost identical numbers. The only difference is that the empire does not have a systematic education system, and the educational habits that each tutor prefers are also different.

In order to roughly understand Lorraine's specific math level, Dusand spent about two quarters of an hour compiling a set of test papers. Lorraine took more than an hour to finish the answering process.

Lorraine, 12 years old this year, has a math level of about the fourth grader of elementary school on Earth. She can master the addition, subtraction, multiplication and division of three-digit numbers, mixed operations and decimals, but the knowledge of plane geometry is basically blank.

At this level of mathematics, don’t worry about the content of mechanical design...it is more important to lay a good foundation.

"Mathematics is a subject that has no shortcuts to go. If you want to master it, you can only do the questions repeatedly to familiarize yourself with the process." Dusander spread his hands helplessly, and then carefully suggested, "Or... I'll find some exercises for you during this period, and you can improve your math level first?"

Lorraine thought for a while, then nodded and emphasized, "If I don't know what to do, then it's a straight question - you have to teach me!"

"Don't worry." Dusand nodded very seriously and said, "As long as we are together during this period, you can ask any questions casually - I will definitely explain them clearly to you."

While the two children were tortured by the one-digit equation together in the lounge, Polina was desperately drawing sketches in her room.

Dusander's two suggestions can theoretically solve the problems encountered by gas engines. However, in the field of mechanical engineering, it is extremely huge to change an idea from a verbal principle explanation to realization.

If she was still in Olin, now she had a 500-pound gold pound, Polina could completely break up the entire research project into several pieces and outsource it. She could hire the laboratory of Imperial University or other metallurgical companies to find a more high temperature resistant and tougher alloy formula. Or hire the laboratory of Imperial University to find the best ether and gas premix ratio in the Nuesar environment.

Anyway, as long as the person is in Olin, as long as there is a golden pound in his pocket, the most top and most useful brain in the entire empire can be used by her.

But she is now in Newar. This is not an Orin-based planet with academic and imperial departments, but a small and beautiful place with its own unique position in the empire for tourism, vacation and financial services.

Materials science and mechanical design have never been Newar's strengths. On this planet, he has no way to do subcontracting research, and he doesn't know where to go.

Then do it all by yourself, it's a little cheaper anyway.

So, after finishing the morning process called "teaching" and actually "discussion", Polina plunged into her room alone, and then began to modify her original design plan with the drawing ruler.

It was not until Baroness Androni and her entourage knocked on her door that she realized that she seemed a little... hungry.

He opened his room door swayingly, and Polina saw Baroness Androni with a serious face and the butler with a gloomy face.

"Miss Polina." After seeing the room with a look of dish and a room full of discarded calculation papers, the housekeeper's face became even more ugly. And Baroness Androni's face turned a little gentler, "Are you... working?"

Polina scratched her messy hair very easily, and then quickly put her hand down. She lifted her skirt, bowed to Androni with a slight twist, and then said embarrassedly, "I will pay attention to keeping the room clean in the future."

"When the great technicians are working, most of them don't pay much attention to the environment." Androni's expression seemed to be even more relaxed. She nodded to Polina and asked, "These things are to improve the products invested by Lord Dusand?"

Polina shook her head first, then immediately widened her eyes, "Lord Dusander has told you?"

After she reached an investment agreement with Dusand last night, Dusand and Lorene emphasized to her for a long time, "This matter must not be known to Mrs. Androni."

As a result, this afternoon, Mrs. Androni knew what was going on.

And I came to ask directly in person... This feeling is really not good.

"Before opening the door, I was thinking of asking you to return the check." Androni didn't care about the messy room, and she stood there and smiled. "Although the money was already Lord Dusand's personal property, the amount of money was still too large for a ten-year-old man."

Polina was of course helpless after hearing this, but after all, five hundred gold pounds... the money was indeed too much, and she was able to understand Mrs. Androni's concerns very well.

Although she had such a sum of money, she could quickly rebuild the improved gas machine and promote it to the market after the experiment.

Polina is ready to accept reality, while Mrs. Androni continues, “But after seeing the results of your work, I feel… maybe his choice is not a bad idea.”

As a nobleman living in Neussal, Mrs. Androni also has many investment projects of her own. She has summarized a set of her own methods in nearly twenty years of investment.

Ultimately, investment is betting on a company and the future of a product. And the people who run the company are people, and the people who develop the products are also people.

Mrs. Androni is more willing to invest in "people" than investment companies or commodities.

As long as she invests in the right person, she can get many times more profits than simply investing.

Although there is still a lack of more detailed understanding,...Polina now looks like a person worth investing in. Dusand's decision doesn't seem that bad now.

"You can keep that check first, but you cannot bring out the money in it between due dates." Mrs. Androni said with a smile. "Lord Dusander has no such experience, so he is not very clear. However, this investment is still valid - I will pay you the funds you need at work. When the check is paid, you can pay me the money you spent during this period of time to the check."

She nodded to Polina and reminded, "It is important to improve the work of invention, but please don't forget to be a tutor."

"Ah! OK!" Polina agreed in a panic, and then said, "The previous tutors have achieved very good work, and Lord Dusand has mastered the professional knowledge very well!"

"But they didn't get along well with Dusand." Every mother likes to hear others praise her children, and Mrs. Androni smiled softly. "I used to wonder if he couldn't get along well with those teachers because he was a male teacher."

Of course, Dusander didn't know that his image in his mother's mind had fallen to the point where he was "difficult to get along with male teachers"... This was a bit outrageous.

After all, he still needs to "cope" with Lorraine's very unfamiliar and inappropriate "hook-up" while explaining the one-center equation.

Lorraine would take the initiative to ask for helping to bear the "liquid contract fee", which is not just for future profits.

Mrs. Ayr, a ritual tutor, has long taught Lorraine the technique of "making men admire". The most important point is, "Let him be your companion rather than your target."

"If you just increase your charm, then what you can attract is just idiots who value appearance." Mrs. Ayer likes Lorene very much and always smiles unconsciously when talking to her. "Miss' appearance is of course a very important part, but we will all age. When you lose your beautiful face, or are no longer as beautiful as before, men who value appearance will abandon you without hesitation."

"Women living in the empire are like this. We only have one way to realize our own value in life." Mrs. Ayer said lovingly, touching Lorraine's head, "Men are unreliable, but we can only rely on them. Therefore, you must choose a partner who will not abandon you. Being companions with them is a good start - although men also like to betray partners, it is less likely to abandon a woman with only appearance."

The purpose of bearing possible liquidated damages is to be justified in order to receive the education of Mr. Polina with Dusand. As long as you can be together frequently, the possibility of becoming a "companion" is higher.

Of course, a simple peer relationship is not enough. Lorraine has always believed that Dusand has some emotional foundation with him. But he is still young after all, and his relationship with him seems to be more like a sibling than an unmarried couple.
