Celestial Mage

Chapter 89 Rosen's First Casting Technique: Dexterous Casting (710)

Rubbing the mentor's back is done more often, and I get used to it.

In the warm and bright separate bathroom of the new home, when Rosen was helping Serrandis to scrub his back, Rosen didn't feel any fluctuations in his heart, and he could even concentrate on discussing spells.

During the discussion, he began to talk about his second purpose for coming back.

"Sweetheart, the Earl explained to me the difference between the natural law system and the logical law system in detail."

Serrandis lay on the edge of the tub, and under the comfort of Rosen's service, she squinted her eyes like a cat.

She lazily said: "I got the earl's personal guidance so quickly, it seems that my apprentice has made a lot of credit."

Rosen smiled slightly: "The merits are all foreign things. What interests me the most is the knowledge of the logic law system. In my spare time, I think carefully, and I have some inspiration."

The war was imminent, so he naturally tried his best to improve his strength, so he used calculus without hesitation.

If it can be used, even very easy to use, then his strength will be greatly improved.

"Let's hear it. Oh, the force is a little heavier. Don't use a bath towel, just use your hands. Here, rub it hard. The instructor seems to have a stiff neck last night."

Rosen helped her loosen her muscles and began to talk in detail.

"Last time, didn't I talk about extending triangular numbers to two-axis crosses?"

"Well, yes. Point it up~ah~~~~ah~~~~ so comfortable!"

"I just thought, can we extend the circumcision technique of the mathematics master Uloy to the two-axis cross mark?"

As soon as he finished speaking, the lazy look on Serrandis' face disappeared instantly.

She suddenly turned her head to look at Rosen, but because the action was too violent and involved her injured neck, she couldn't help it.

With a scream, he immediately turned his neck back.

"Hurry up and help the instructor rub it~ah, it feels like my neck is about to break!"

After finishing speaking, he immediately said: "Don't worry about the instructor, just keep talking!"

Rosen continued to explain.

"Master Uloy divides the circle with triangles to obtain accurate pi. But obviously, no matter how many triangles are used to divide the circle, the exact pi cannot be obtained."

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

"So, I borrowed the concept of 'infinity' and changed the triangle to a more computationally efficient rectangle. You see, that's it."

As soon as he had a thought, the mage's hand picked up the water splash, and drew a cross and a parabolic curve on the water surface.

Because of the soreness in her neck, Serendis turned around and looked at her, her onyx-like eyes shone brightly.

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

Rosen was immersed in his own thinking, and didn't notice Serrandis' movements. He started from the lowest level of thinking, and gradually introduced the knowledge of calculus.

Serrandis listened very intently, his eyes became brighter and brighter, and a thought kept echoing in his mind.

"God of Gold, what kind of apprentice did I accept?!"

Rosen didn't notice her change.

He focused on controlling the clear water, drawing mathematical formulas one after another in the air, and behind the beautiful formulas was Serendis's beautiful snow-white body.

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

In a trance, time seemed to freeze into eternity.

Serrandis subconsciously clenched her delicate lower lip, looking through the shining mathematical formula with blurred eyes, looking at the young face behind the formula, she clearly felt the light of wisdom shining in the dark blue eyes .

After a while, Rosen finished talking about the core idea of ​​calculus, namely 'infinity', also called 'limit'.

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

"But fortunately, I have nothing to do these three days. We can study it together. What do you think?"

"Ah~~ This is a great honor for the instructor!"

She couldn't stay in the bathtub any longer, so after washing casually, she put on her dress, sat in a big armchair, picked up a pen, and began to scribble on the manuscript.

After Rosen cleaned the bathtub, he lit the fireplace vigorously, making the air in the whole room warm like spring.

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

During this process, Rosen had advanced modern mathematics in mind.

He is from a high position and can easily control the details of mathematics.

Even if the memory is a bit fuzzy, you can open the adventure log and return to the university classroom of the previous life to seek clear memory.

And Serendis is knowledgeable and keen, and has the tenacity to study knowledge with great concentration, and his understanding of spell knowledge is far beyond Rosen.

In short, she is a pure, extremely good scholar 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 important and unprecedented application of logic spells!

In the middle of the night on the third day, there was a stack of moderately thick manuscript paper on the desk in the study, the first page of which read "Spellcasting Smartly".

This is not a spell, but a skill to cast a spell.

Serrandis looked at the manuscript paper, with deep reluctance in his eyes.

"The good time is really short, but it's a pity that you will leave early tomorrow morning."

Rosen was carefully analyzing the new spell structure on the manuscript paper with a pen, and his mind was not idle, and he was constantly inputting these new spell knowledge into the spell analyzer.

"Mentor, it's just a brief separation, I will be back soon."

"Is the outside world really that wonderful?"

"There are two kinds of books in the world. The first is recorded on paper, and the second is recorded among mountains and rivers. The content of the latter is infinitely many times that of the former."

Serrandis sighed softly, looking at his apprentice with a blurred gaze.

"Well, you can always say something full of philosophical thoughts."

At this time, Rosen completed the calculation of the new spell, and he handed the calculation paper to Selandis.

"Mentor, I finished the calculation and found no mistakes. Check to see if there are any omissions."

Serrandis took the manuscript paper and checked it carefully.

After a while, she gently put down the manuscript paper.

"I didn't find a problem either. But after all, this is a brand new mathematical idea, and the time is short. I can't confirm whether there is a problem with this idea itself."

Rosen smiled faintly: "Whether there are any problems or not, it is still very useful. Let's give this new idea a name, mentor."

Serrandis tilted his head and thought for a while, then shook his head: "I can't think of it, why don't you come and get one?"

Rosen had thought about it a long time ago, and said, "Its appearance is to describe smooth and continuous complex curves. How about taking the 'flow' of 'smooth' and the 'number' of mathematics to form the 'number of flows'?"

Serrandis' eyes lit up: "Liu Shu. What a good name, let's call it that."

Rosen continued: "As for whether there is a problem with this new idea. It is also easy to verify."

"Should I try the new spell directly? If there is no problem, then the spell will definitely be cast successfully."

Serrandis gave Rosen a blank look: "If you make a mistake, the spellcasting will fail. With your fire-polar mana, you will light yourself like a big candle."

This kind of spellcasting accident is caused from within, and defensive spells are basically useless.

Unexpectedly, Rosen stood up and retreated to the corner.

"Try it, and then you'll know."

In fact, he has already completed the simulated spellcasting in the spell virtual machine, and he knew that the spell would be fine.

Serrandis was startled: "No!"

'Shh~~'

Rosen smiled lightly, the mana surged, flowing according to the imaginary spell structure, and it was quickly constructed successfully.

A glaring bright spot the size of a sesame seed slowly appeared in the air. Afterwards, the bright spot became bigger and bigger, but the intensity of the emitted light never changed.

This shows that the spell power has not changed, only the scale of the spell 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 was supposed to be asleep, also appeared in the form of a mana phantom, watching nervously.

When the bright spot reaches the size of a jujube pit, the volume temporarily stabilizes.

Rosen said, "Mentor, this is a 20.00% scale miniature missile."

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

"It is now 20.00%. 39 eleven hundred. One hundred fifty 220"

"To the limit!"

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

When everything returned to calm, the two Serendis spoke in unison.

"Success."

Rosen nodded slightly: "Yes, it worked."

"Teacher, based on the latest dexterous spellcasting skills, the spell scale of the standard missile spell can be adjusted between 220% and [-]% to suit different needs."

Although due to the unique nature of mana, it is still not possible to cast spells without restraint, but such a wide casting space is undoubtedly a huge leap forward for logical spells!
And with the blessing of this powerful spellcasting skill, Rosen felt that his combat power could at least double.

On the other side, seeing Rosen's experiment was successful, Serendis felt itchy in her heart. She calmed down and began to cast spells.

Compared with Rosen's fire polar mana, her attribute is silver moon, and the light spots are silver, just like the stars in the sky.

However, because her contact time was too short, her understanding of the infinite thoughts of flow numbers was still insufficient, so when changing the spell form, it was not as smooth and natural as Rosen.

But this is not a problem, with a lot of practice, you will become proficient naturally.

When she finished casting the spell, her cheeks flushed and her eyes sparkled.

"Rosen, I can feel that this brand-new mathematical idea has huge potential to be tapped. If we can study it in depth, maybe we can create a high-level, or even a master-level pure logic spell!"

If that's the case, then their names will be recorded in the annals of history forever, no, no, just the creation of Liu Shuo is enough to shine in the annals of history!
Rosen nodded in agreement: "I think so too."

"Hey, it's a pity you're leaving tomorrow."

Serrandis sighed for the second time.

Rosen smiled and said, "I'll be back soon."

"Oh, by the way, the body is also very important. When I'm not around, don't forget to eat and sleep and forget about life."

With Serrandis' character, he would definitely focus on the number of streams, so he reminded him so.

"Rosen, you are really worried like an old father."

Serrandis tried to resist.

"Mentor~~" Rosen raised his tone.

Selendis immediately compromised.

"Okay, I'll pay attention."
