It took Dusand a full afternoon, plus two cups of black tea, a bouquet of flowers, and six cream cakes, to get Lorraine back together. When he saw Lorraine's smile again, Dusand felt a fine layer of sweat break out on his back.

People in their thirties still have to do this kind of thing...... Dussaint felt a little sad. But he quickly regained his spirits - in fact, such Lorraine has some flavors. This is better than the moody puppet lady.

"Are the improvements you mentioned today really useful?" Eating Dussand's cream cake for the coming week, Lorraine decided to care about her fiancé's academic development, "I think Teacher Polina seems to be very excited. ”

"All I'm proposing are unproven ideas and suggestions." Dussand, habitually modest, said, "Luckily, it looks like Miss Polina was really inspired. ”

"I spent the day today, but I didn't write anything in my notebook." Lorraine muttered, "It's not a good deal." ”

Lorraine had something to say, and Dusundre smiled bitterly and said, "Or...... Shall I teach you the basics? Let's start with the math. ”

Dussaint himself hadn't studied the imperial rules and the like very well, so he was exempt from teaching people.

But he's pretty good at math.

Empires are the same as Earth's mathematical system. It's the same decimal system, and the same numbers are used. The only difference is that the empire did not have a systematic education system, and the educational habits of each tutor were different.

In order to get a rough idea of Lorraine's specific math level, Dussaint spent about two quarters of an hour compiling a set of test papers. And it took Lorraine more than an hour to finish the answering process.

Lorraine, 12 years old, is about the same level of math as a fourth-grader on the planet. 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, let's not care about the content of mechanical design...... It's still more important to lay a good foundation.

"Mathematics is a subject where there are no shortcuts. If you want to master it, you can only do the problem again and again to familiarize yourself with the process. Dussaint spread his hands helplessly, and then cautiously suggested, "Otherwise...... I'll find you some exercises to do during this time, and you can improve your math level first? ”

Lorraine thought for a moment, then nodded and emphasized, "If I don't know how to do it, then it's a direct problem - you have to teach me well!" ”

"Don't worry." Dussaint nodded very solemnly and said, "As long as the two of us are together during this time, you can ask any questions you want—I will definitely explain them to you." ”

While the two children were tormented by the unary equation together in the lounge, Polina was desperately sketching in her room.

Both of Dussaint's proposals could theoretically solve the problems encountered by the gas engine. However, in the field of mechanical engineering, the time, energy and money required to move an idea from a verbal principle to a realization can be enormous.

If she was still in Olin, Polina, who now had a full 500 gold pounds on her, could have broken up the entire research project into several pieces and outsourced them. She could hire the laboratories of Imperial University or other metallurgical companies to find alloy formulations that were more resistant to high temperatures and tougher. Or hire the Imperial College London lab to find the best ether and gas premix ratio for the Newsal environment.

Anyway, as long as people are in Olin, as long as they have gold pounds in their pockets. The best and best brains in the entire empire can be used by her.

But, she is now in Newsar. This is not Orin's predominantly academic and imperial planet, but a small, scenic place that has its own unique place in the Empire for its tourism and financial services.

Materials science and mechanical design have never been Newsal's strong suits. To do subcontracted research on this planet, Polina has no way, let alone where to go.

Then do it all yourself, it's cheaper anyway.

So, after finishing the morning's process of "teaching" and "discussion", Polina went into her room alone, and then began to revise her original design with a drawing ruler.

It wasn't until Baroness Andronie and her attendant knocked on her door that she realized she seemed to be ...... Hungry.

Swinging open the door of her room, Polina saw the serious-looking Baroness Androni, and the grim-faced butler.

"Miss Polina." The butler's face became even more ugly after seeing the room with a discarded face and discarded calculation paper all over the floor. Baroness Andronie's face was a little softened, "What are you......?" At work? ”

Polina scratched her messy hair very easily, and then quickly put her hand down. She lifted her skirt and bowed to Androni crookedly, then said embarrassedly, "I'll take care to keep the room tidy in the future." ”

"When the big technicians are working, most of them don't pay much attention to the environment." Androni's expression seemed to soften even more, and she nodded towards Polina and asked, "These things are just to improve the products that Lord Dusand has invested in, right?" ”

Polina shook her head at first, then her eyes widened immediately, "Lord Dussander has already told you?" ”

After she reached an investment agreement with Dusande last night, Dussaint and Lorraine deliberately emphasized to her for a long time, "This matter must not be known to Mrs. Andronie." ”

As a result, this afternoon, Madame Androni knew what had happened.

And I came directly to the door to ask in person...... It's a really bad feeling.

"Before I opened the door, I thought I would have to ask you to return the check." Androni didn't care about the messy room, she stood there and smiled, "Although that money is already Lord Dussand's personal property, it is still too much for a ten-year-old man. ”

Of course, Polina was a little helpless when she heard this, but after all, five hundred gold pounds...... It was indeed too much money, and she was well able to understand Lady Andronie's concerns.

With this amount of money, she was able to quickly rebuild an improved gas engine and put it on the market after experimentation.

Polina was ready to accept reality, and Lady Andronie continued, "But, after seeing the results of your work, I feel ...... Maybe his choice wasn't a bad idea. ”

As an aristocrat living in Newsal, Madame Androni also has a number of her own investment projects. And in nearly 20 years of investment, she has summed up a set of her own methods.

At the end of the day, investing is betting on the future of a company, a commodity. And it's the people who run the company, and it's the people who develop the products.

Rather than investing in companies or commodities, Mrs. Androni prefers to invest in "people".

As long as she invests in the right person, she will be able to make many times more profit than she would have invested alone.

Although there is a lack of more detailed understanding, it is ...... Now Polina does look like a good investor. Dussand's decision doesn't seem so bad now.

"You can keep that check for now, but you won't be able to withdraw the money until it expires." Lady Androni smiled and said, "Lord Dusand doesn't have such experience, so he doesn't know very well. Still, the investment is valid – the money you need for your job, I pay you. When the check is due and cashed, you can pay me the money you spent during this time. ”

She nodded at Polina and admonished, "It's important to improve your work on inventions, but don't forget your job as a governess." ”

"Ahh Good! Polina agreed in a bit of a panic, and then said, "The previous tutors have done very well in their work, and Lord Dussand's expertise is very good!" ”

"But they didn't get along well with Dussand." Every mother likes to hear people compliment her children, and Mrs. Androni smiled gently, "I used to wonder if he didn't get along well with those teachers because he was a male teacher." ”

Unbeknownst to Dussand, of course, that his image in his mother's mind had been reduced to "being difficult to get along with male teachers...... That's a bit outrageous.

After all, he also needs to "deal with" Lorraine's very unfamiliar and untimely "hookup" while explaining the unary equations.

Lorraine will offer to help bear the "liquidated damages", and that is not only for the benefit later.

Lady Eyre, who is a governess of etiquette, has long taught Lorraine the art of "making men admire". And the most crucial of these is, "Let him be your companion and not your goal." ”

"If it's just to increase your charm, then you can attract just idiots who value your appearance." Mrs. El liked Lorraine very much, and always smiled when she spoke to her, "Of course, a lady's appearance is a very important part, but we all get old. When you lose your beauty, or are no longer as beautiful as before, men who value appearance will not hesitate to abandon you. ”

"Women living in empires are like this, we only have one way to realize the value of our lives." Mrs. El touched Lorraine's head lovingly and said, "Men are unreliable, but we can only rely on them. So, be sure to choose a partner who won't abandon you. Becoming a companion with them is a good start - although men also like to betray their partners, it is less likely than abandoning a woman who only looks good. ”

Bear the possible liquidated damages, the purpose is to come and receive the education of Teacher Polina with Dusander. As long as you can be together often, you are more likely to become a "companion".

Of course, peer relationships alone are not enough. Lorraine has always believed that Dussaint has some emotional basis with herself. But he is still young after all, and his relationship with himself seems to be more like a brother and sister than a fiancé.

So, some "appropriate" hints are also important. She had to make Dussander realize that she wasn't just a sister two years older than him, and that she was ...... Or the opposite sex.
