Bathing for the teacher and even bathing together, the more times I have taken it for granted.

In the warm and bright private bathroom of his new home, when he rubbed Thrandis's back, Lawson's heart did not fluctuate at all, and he could even concentrate on discussing spells.

During the discussion, he began to state his second purpose for rushing back.

"Little sweetheart, the Count explained to me in detail the difference between the natural law system and the logical law system."

Thrandis lay on the edge of the tub, her eyes narrowed like a cat under Rosen's comfortable hand.

She said lazily: "It seems that my father has made a lot of contributions to the personal guidance of the earl so quickly." ”

Rosen smiled slightly: "Whatever the credit, it's all foreign things." What interests me the most is the knowledge of the logical law system. In my free time, I thought about it, and I got some inspiration. ”

The war was imminent, so he naturally tried his best to improve his strength, so he did not hesitate to move out of calculus.

If he can use it, even if it is very useful, then his strength can be greatly improved.

"Tell me about it. Oh, the force is a little heavier, don't use a bath towel, just use your hands. The shoulder blades are here, rubbing hard, and my daughter seems to have fallen a little stiff last night. ”

Lawson helped her loosen her muscles and began to elaborate.

"Last time, didn't I say that trigonometric numbers were generalized to the two-axis crosshairs?"

"Well, yes. Then point to the top~~~~~Ah~~~~ It's so comfortable! ”

"I wondered if I could extend the circumcision technique of the mathematician Ulroy to the two-axis crosshair."

As soon as he finished speaking, the lazy look on Thrandis's face disappeared in an instant.

She turned her head abruptly to look at Lawson, but she couldn't help it because the movement was so violent that it involved her injured neck

Let out a scream, and immediately turn his neck back.

"Hurry up and help my daughter rub it~ Ah, I feel like my neck is going to break!"

After speaking, he immediately said: "Leave your daughter alone, the father continued!" ”

Rosen went on to explain.

"Master Ulroy used triangles to divide circles in order to obtain accurate pi. But obviously, no matter how many triangles are used to divide a circle, you will not get an exact pi. ”

"Or, in other words, you can only get accurate pi by cutting with infinite triangles."

"So, I borrowed the concept of 'infinity' and changed the triangle to a rectangle that is easier to calculate. You see, that's it. ”

As soon as he thought about it, the mage's hand made a splash and drew a cross and a parabolic curve on the water.

Because of the pain in her neck, Thrandis turned directly to look, and looked at it, her red onyx-like eyes shining brightly.

"Ah~~ How can there be such a subtle thought in the world!"

Lawson was immersed in his own thoughts, and did not notice Thrandis's movements, and continued to rub the other party's body with his hand, and suddenly felt that the bottom of his hand felt soft, and when he looked down, he pretended to be okay and withdrew his hand.

Next, he starts at the very bottom of his mind, and little by little he leads to the knowledge of calculus.

Thrandis listened intently, his eyes brightening brighter, and a thought echoed in his mind.

"The Golden God is above, what kind of apprentice have I accepted?!"

Rosen didn't notice the change in her.

He was intently controlling the clear water, drawing mathematical formula after formula in the air, and behind this beautiful formula was the beautiful snow-white body of Thrandis.

The smooth and heavy oak tub, the white beauty, the bright petals, and the clear warm water are all intertwined by an unprecedented and incomparably exquisite logical wisdom.

In a trance, time seems to freeze into eternity.

Thrandis subconsciously bit her delicate lower lip, and her misty gaze looked through the glittering mathematical formula, looking at the young face behind the formula, and clearly felt the light of wisdom shining in her dark blue eyes.

After a while, Rosen finished talking about the core idea of calculus, which is 'infinity', also known as 'limit'.

"Mentor, these are my initial thoughts, they are very immature, and there are many places that cannot withstand scrutiny."

"But fortunately, I don't have anything to do in the past three days, so we can study it in depth together. What do you think? ”

"Father, this is a great honor for my daughter!"

She couldn't stay in the tub any longer, so she washed it casually, put on her dress, sat down in the big chair, picked up the pen, and began to write the manuscript.

After Lawson cleaned the bathtub, he lit the fireplace vigorously, making the air warm as spring.

After that, the two of them sat down at the table and seriously studied the application of new mathematical ideas.

In the process, Rosen had modern mathematics ahead of his time.

He has a commanding eye and can easily control the details of mathematics.

Even if your memory is a little fuzzy, you can open your adventure journal and go back to the university classroom in your previous life to find clear memories.

Thrandis, on the other hand, was erudite and keen, and had the tenacity to devote himself to study, and his knowledge of magic far surpassed that of Lawson.

In short, she was a pure, extremely good scholar-type mage.

With the cooperation of the two sides, the entry was very fast, much faster than Rosen imagined.

It only took three days to get a very significant and unprecedented application of logic spells!

In the middle of the night on the third day, there was a stack of manuscript papers on the table of the study, the first of which read "Dexterous Spells".

It's not a spell, it's a trick to release it.

Thrandis looked at the manuscript paper with a look of reluctance in his eyes.

"Good times are short, but it's a pity that you're leaving early tomorrow morning."

Rosen was holding a pen and carefully analyzing the new spell structure on the manuscript paper, and his mind was not idle, constantly entering these new spell knowledge into the spell parser.

"Mentor, it's only a brief separation, I'll be back soon."

"Is the outside world really that exciting?"

"There are two kinds of books. The first is written on paper, and the second is written between mountains and rivers. The latter kind of book is infinitely many times more content. ”

Thrandis sighed lightly, looking at his apprentice's gaze a little misty.

"Hmm~ You can always say something philosophical."

At this point, Lawson finished calculating the new spell and handed the talise to Thrandis.

"Mentor, I'm done the math and I didn't find any mistakes. See if there's anything missing. ”

Thrandis took the paper and examined it carefully.

After a long moment, she gently lowered the manuscript paper.

"I didn't see any problems either. However, this is a completely new mathematical idea, and the time is short, so I can't confirm whether there is a problem with this idea itself. ”

Rosen smiled faintly: "Whether there is a problem or not, it is still very useful, give this new idea a name, mentor." ”

Thrandis tilted his head and thought for a moment, shaking his head: "I can't think of it, you can get one?" ”

Rosen had already thought about it, so he said: "It appeared to describe a smooth and continuous complex curve. How about taking the 'flow' of 'flow' and the 'number' of mathematics to form the 'flow number'? ”

Thrandis's eyes lit up: "Flow number. That's a good name, just call it that. ”

Rosen continued: "As to whether there is a problem with this new thinking. It's also easy to verify. ”

"I'm going to try a new spell directly? If it's okay, then you're sure to be able to cast a spell. ”

Thrandis gave Rosen a blank look: "If it's wrong, the spell will fail." With your fiery power, you will light yourself into a large candle. ”

This type of spell casting accident occurs from within, and defensive spells are largely useless.

Unexpectedly, Lawson stood up directly and retreated to the corner.

"Just try it."

In fact, he had already completed the simulated spell casting in the spell virtual machine, and he knew that this spell was fine.

Thrandis was startled: "Don't! ”

'Shh~~'

Rosen smiled lightly, and the mana surged, flowing according to the imaginary spell structure, and the construction was quickly successful.

A blinding bright spot the size of a sesame seed slowly appeared in the air, and then the bright spot grew larger and larger, but the intensity of the light never changed.

This shows that the spell strength has not changed, only the spell size has changed.

Anna watched with bated breath.

Because of her nervousness, she clenched her hands into fists so that her joints turned white, and Alice, who should have been asleep, also appeared in the form of a magic phantom at this time, looking at it with the same nervousness.

When the bright spot reaches the size of the jujube pit, the volume is temporarily stable.

Rosen spoke: "Mentor, this is a miniature missile of 20 percent scale. ”

Immediately after, the size of the missile continued to expand.

"Now it's twenty percent. Thirty nine thousand or one hundred. One hundred and fifty two hundred twenty"

"It's the limit!"

The missiles in the air were slowly canceled, and when the light disappeared, Rosen breathed a sigh of relief, and Thrandis also breathed a sigh of relief.

When all was calm again, the two Thrandis spoke in unison.

"It worked."

Rosen nodded slightly: "Yes, it worked." ”

"Mentor, based on the latest dexterous spell casting techniques, the spell size of the standard missile technique can be adjusted between ten percent and two hundred and twenty percent to suit different needs."

Although due to the unique nature of mana, it is still not possible to achieve truly unrestrained spell casting, but such a wide spell casting space is undoubtedly a huge leap forward for logic spells!

And with the blessing of this powerful spell-casting skill, Lawson felt that his combat power could at least double.

On the other hand, seeing that Rosen's experiment was successful, Thrandis's heart was itching, and she calmed down and began to cast spells.

Compared to Rosen's fire polarity mana, her attribute is a silver moon, and the points of light are silver, just like the stars in the sky.

However, because the contact time was too short, her understanding of the infinite thought of the flow number was still somewhat insufficient, so when she changed the spell form, she was not as smooth and natural as Lawson.

But that's not a problem, with a lot of practice, you'll be able to become proficient.

After completing the cast, her cheeks flushed and her eyes lit up.

"Rosen, I can feel that this brand new mathematical idea has great potential to be tapped, and if we can study it deeply, maybe we can create a high-level, or even master-level pure logic spell!"

If that's the case, then their names will forever go down in history, no, no, the creation of the flow alone is enough to glorify the annals of history!

Rosen nodded in agreement: "I think so too." ”

"Hey~ It's a pity that you're leaving tomorrow."

Thrandis sighed a second time.

Rosen laughed, "I'll be back soon." ”

"Oh, yes, the body is very important, too. When I'm not around, don't forget your life and forget your life. ”

With the character of Thorandis, he will definitely focus on the flow of numbers, so he reminded him so.

"Rosen, you're as worried as an old father."

Thrandis tried to resist.

"Mentor~~" Lawson raised his tone.

Thrandison compromised.

"Okay, I'll take notice."
