Lord: Marry the villain's daughter at the beginning?

The next day, Lind brought Reina and Isa to visit Lisha and also to confirm the research results of the Holy Talisman Society.

In fact, Lind has already prepared for the worst, which is that the research success of the Rune Saint Society is completely meaningless, but in that case it would only mean that there would be one more first-level rune master suffering from magic disease in the territory. Although the territory's finances are a bit tight due to the increase in population and the single industrial structure, it is not at all to the point where it cannot even feed two more mouths.

"Good morning, Ms. Lisha."

Linde walked into the house casually and greeted Lisha.

Lisha seemed at a loss when faced with the personal visit of the lord and his wife. Although Lisha's father's title was higher than Linde's, the family title had been inherited by other people. Lisha herself did not have any title. In addition, she had been treating illnesses and doing research since she was a child, so she was not familiar with the etiquette between nobles.

However, when Lisha saw the lord's wife pull out a chair and sit down without any courtesy, she suddenly relaxed a lot.

This territory seems to be different. The lord and his wife don't seem to pay much attention to red tape, especially the wife. It seems that she has not even learned the basic etiquette courses. She just wants to make the point.

"Good morning, my lord."

Lisha held the research notebook and bowed respectfully to Linde.

Linde nodded slightly. Lisha relaxed after secretly glancing at Rena. This made Linde feel that it was the right decision to bring Rena here. It helped people with low self-esteem to gain confidence. Rena, you are so great.

Of course, bringing Reina here was not just to relieve Lisha's nervousness. Reina and Isa could be said to be the two highest-ranking professionals in the territory. Although Linde could also use magic and divine arts, those were all because he inherited the skills of the heroine in the archive. Linde himself didn't even know why he could use these magic and divine arts.

The magic that Lind now possesses is a pure black box technology, just like a bicycle. Everyone knows that a pedal stroke can keep a two-wheeled bicycle balanced and moving, but the scientific community did not have a specific conclusion on the exact principle until Lind traveled through time.

"Are you used to living here? I don't know much about magic sickness, is there anything I can help with?"

Facing the lord’s concern, Lisha lowered her head and hid her expression behind the thick lenses of her glasses.

"This is already better than the place I live in the Holy Talisman Association. I will cure the magic disease myself. Thank you for your concern, Lord."

It sounded like he was just trying to show off, but Linde didn't intend to delve into it. He took out the information the boss lady gave him yesterday and said, "I read your detailed information last night. Although you are a first-level rune master, you don't actually rely on sensing magic power to draw runes and magic circles, right?"

Although Linde thought his tone was very gentle, Lisha immediately became nervous and replied anxiously: "Don't worry, Lord. Although I can't sense and mobilize magic power, I will never make mistakes when drawing runes!"

Linde quickly noticed the key words in Lisha's words.

"Absolutely? How do you guarantee that the runes you draw will never go wrong?"

There is actually no standard template for drawing runes and magic circles, because each professional has more or less personal habits when drawing runes and magic circles.

The reason why these runes with strong personal colors rarely make mistakes is that professionals who can sense and mobilize magic power can constantly use magic power to verify whether the rune can run, whether the magic power flows smoothly, and which part of the rune or magic circle needs adjustment.

If drawing a rune is like writing a string of code, professionals can write and run at the same time, constantly debugging.

But Lisha can't do that. Lisha, who can't sense and mobilize magic power, is like writing code in a notepad. Only after she finishes writing and starts running, she will know whether the code can run.

Even after the error was reported, Lisha couldn't determine which link had gone wrong.

"I'm very sorry, Lord. I... I'm not sure if the rune would be wrong. I just said it out of fear that you would fire me."

Lisha's head shrank completely, and Linde realized that his tone just now was too serious.

If Lisha was really afraid of being expelled, she would not have said that. It was obvious that she had other ways to ensure that the rune would not go wrong.

Just when Linde wanted to comfort Lisha but didn't know how to start, Isa comforted Lisha in a gentle tone: "Don't be nervous, the lord just wants to know how you make sure the runes won't go wrong, he doesn't want to fire you. This is not a magic association with strict rules, and there are not so many red tapes. You just need to tell us what you know, and you can tell us directly if you have any difficulties."

Reina at the side also followed suit and said, "That's right, Isa was originally a traitor. Our Lars family is not so poor that it can't afford to support a rune master, brother, don't you think so?"

Linde looked at Lena speechlessly. If you don't know how to speak, you don't have to.

Perhaps because of Isa's unique charm as the heroine, Lisha glanced at the notebook in her hand and said to everyone, "It's a pattern."

"law?"

This time it was Isa's turn to be surprised. As the only one among the three who had received formal magic education in the royal capital and studied seriously, she knew how outrageous the three words Lisha said were.

The magic circles on the market today, even the runes and magic circles in textbooks, all carry the strong personal colors of those rune masters, and there is no unified rules or style at all.

Is there a pattern in the arrangement of runes? Indeed, there is, but unless you know all the runes and their arrangement in this world, it is impossible to combine the ever-changing runes based on the pattern alone.

"Yes, it is a law, and the law can be derived through logic and calculation."

Perhaps because she was talking about the area she was best at, the girl suddenly became very excited and full of confidence.

"To be more precise, it's a formula. Once the position of a rune is determined, the position of the next rune can be deduced through the calculation formula by considering the ultimate purpose of the rune, its output power, and the available connection methods. As long as the positions of three runes are confirmed, the positions of other runes in a magic circle can theoretically be analyzed one by one."

After that, in order to make it easier for everyone to understand, Lisha took out her tools for drawing runes and drew a magic circle in the room on the spot.

"Just like if we want to draw a water vapor magic circle now, we need to use the root water, spray grass powder and moon flower to make water condensation runes, then we can confirm the output power and connection method of the water condensation runes made with these materials."

Lisha concentrated on crushing and mixing the materials mentioned, then applied them to the carving knife and began to draw runes on the floor.

"Use all the ways the Water Condensation Rune is connected to confirm the positions of the other two runes that are not on the same straight line as the Water Condensation Rune."

As the carving knife danced on the floor, Lisha quickly drew two more runes.

"Then the three runes that are not in the same straight line can confirm the general shape of the magic circle. Combining this shape, we can deduce the remaining runes one by one."

Under the shocked gazes of Isa and Reina, Lisha was like a calm artist, calculating on the draft paper while drawing the magic circle with the carving knife in her hand.

Linde looked at the draft paper next to Lisha and found it looked more and more familiar.

Because when Lisha was carving the magic circle with a carving knife, she also used a pen to draw a coordinate axis on the ground as an auxiliary line.

Then I wrote and drew on the coordinate axis using a bunch of numbers and incomprehensible formulas.

Mathematics... more precisely, geometry, equations, and linear algebra.

There were also many symbols and formulas that Linde could not understand at all. The draft paper full of numbers and symbols reminded Linde of the mathematics teacher in his previous life whose head was brighter than a light bulb and who was often confused by students' questions and was afraid to stay in the office.

While Linde was still in a daze, Lisha had already drawn the magic circle, took off the necklace from her neck, and placed it at a certain position on the magic circle.

Immediately, the magic circle was successfully activated, many condensed water droplets appeared on the edge of the table, and the air in the room began to become a little humid.

"That's probably... that's it."

After drawing the magic circle, Lisha returned to her nervous and unconfident look.

"May I take a look at it?"

Linde came back to his senses and pointed at the draft paper on the ground.

"Of course, you are the lord, and you bought me, so of course you can."

Lisha handed the draft paper to Linde respectfully.

Lin De looked at the scribbles on the draft paper in a state of collapse, cursing in his heart: "Damn it, I thought this world was all about metaphysics, and now you tell me to believe in science?"
