When she was in Auvergne, Theresa had already seen the pattern of the fortress designed by Sinampe, and although she had not personally experienced the battle formation, she intuitively realized that it was a revolution compared to the traditional fortress.

When Theresa recommended Sinampe to the king, she not only gave him the ammunition for the Blackstar pistol, but also gave the king the blueprints for the fortress. Later, after Theresa's explanation, the king also recognized the merits of the fortress, and this became one of the reasons why the king recognized Sinampei's real talent and learning when they first met.

It's just that Theresa won't say more about this in front of Sinampei, just ask him for credit.

Hearing Sinampe say that he wanted to improve the defense of Pali City, Theresa was curious: "Si, do you still want a revolutionary design like the fortress?"

Sinan Pei shook his head: "The fortress is already a design that is enough to open up a new era, although there are more plans in my head, but they are probably not suitable for this era." ”

"Then you want to give Pali a massive makeover?" Theresa looked sad, "but the king certainly won't be able to come up with that much money—if you don't have a mature plan for casting cannons, I'm afraid that just casting cannons will be enough to ruin his family." And it's not something that can be done in a year or two. ”

"Rest assured, this time the plan I proposed is not so complicated. Sinan Pei smiled proudly, "What I want to say is only to change the outside of the vertical city wall to a sloping one." Well, that's it. ”

Although modern military tactics such as anti-slope fortifications are completely unnecessary in the face of today's rudimentary long-range firepower, inclined walls are still useful in the face of shelling - anyone who has studied physics can understand the advantages of sloping walls in the face of shelling if they think about it for a while.

At the same time, the sloping walls are also effective in defending against enemy ladders.

In the era when there was no artillery, no one wanted to break their heads to make some unusual sloping walls. However, the modern city defense takes into account the problem of inclination angle, which is also due to the progress of scientific and technological theories, otherwise even the Khwarazm people who have hollowed out their minds will only rely on experience and think of building a vertical city wall on the high ground that provides an inclined plane.

Theresa's two small hands gestured in the air, dazed, apparently not yet turning.

Sinampe took Theresa's hand and came to the desk, on which quills, ink, and paper were already arranged.

Then he wrote and sketched for Theresa to talk about simple physics theories, and at first Theresa listened with great interest, but when he talked about the importance of trigonometric functions for artillery, he gave up with a bitter face: "Si, how can you be like those university professors in Saranyi, and pull others to talk about these strange things. ”

At the time of Auvergne, Sinampe already knew that the regions on the Eurginian continent where capitalism began to develop already had primitive universities, among which the Sarani region was the most important. It is precisely because of the political disunity, coupled with the superior transportation conditions and the prosperity of the city-state republic, that an open academic environment has been created. An open academic environment is one of the conditions for great change.

This knowledge may seem strange to you, but in a few hundred years, it will certainly be the foundation that everyone must master. Thinking of this, Sinampei was confident and calm, "You have to believe me, the world will change because of technology." ”

Theresa patted her head, "Oh, by the way, I suddenly remembered that the letter from Master de Rice is still with me!"

"Letter?" After Theresa said this, Sinan Pei also remembered this stubble. The mysterious manner in which de Les de Les seemed to be aroused aroused his curiosity.

Theresa nodded, then tugged at the rope that looked like a light switch, and in a few moments a servant knocked on the door.

There are similar devices in Auvergne's castle, so Sinampe is not so surprised. In fact, at the beginning, he also scolded the laziness of the nobles, but it didn't take long for Sinampei to do without this device - especially when he was working.

"Please come in. Theresa said casually.

It was Carla who came in, she didn't care what the two of them were doing in this room, she just asked flatly: "Your Highness, do you have any instructions?"

"Kara, you've just come back, so don't bother with that. Theresa frowned, "Who is so lazy?

Carla shook her head: "This is what I took the initiative to ask, compared to Mr. Si, who was seriously ill and put into work as soon as he recovered, I have not done enough." ”

"Oh, Si, what's going on?" Theresa grabbed Sinampe's hand and looked at him worriedly.

"It's not a big deal, it's just a small cold. Sinampei snorted and pretended not to care. As the saying goes, illness comes like a mountain, illness goes like a thread, until now, he is still a little tired, but he doesn't want to show weakness in front of girls.

Seeing Sinampei's resolute look, Theresa didn't know what to say, so she nodded and turned to Kara, "Can you help me bring the letter from Master Dress? It's in my suitcase, you should know, Miss Kara." ”

"As you wish. Kara took the order, and soon retrieved what Theresa had requested.

"What's in this letter?" Before opening it, Sinampei asked Theresa first.

Contrary to Sinampe's expectations, Theresa smiled and said, "I don't know, how can I be embarrassed to read the letter that Master De Les wrote to you. ”

This was a little surprising to Sinampei, in fact, subconsciously, he hoped that Theresa secretly read the letter written by De Rice to himself, because he had to understand that if a woman did this, it meant that she cared about herself.

"So this isn't a letter to myself. Sinan Pei smiled bitterly, "I thought I had the qualifications to learn magic, but I have been waiting for so long." ”

"Huh, not for you?" Theresa looked puzzled, "not for you, Master De Rice, why did he ......?"

Si Nanpei couldn't figure out whether this goblin little girl was really confused or fake, but he didn't care so much: "This is a letter of recommendation, a letter of recommendation that recommended me to Pali University." ”

"Did he recommend you to the governing committee or to a professor?" asked Theresa.

"It seems to be a professor named Flesova......" Sinampe sighed, "There are too many people named Flesova!"

"Is it Master Flesois?," Theresa asked with a smile.
