Probably hearing Rosen's heart, after dinner, the dignified Thrandis reappeared.

She sat upright in the chair, her face was serious, her eyes were awe-inspiring, and her tone was unquestionable, and she looked like a serious magic teacher.

"The first lesson is the basics, and you have mastered it very well."

"I'm going to have the second lesson today."

"In this lesson, I'll teach you a formal low-level spell. And in the process of explaining the spell, let you realize the true meaning of the spell. ”

'Wow, it's full of dry goods again!' ’

Rosen's spirit has never been more concentrated than ever, ready to enjoy this delicious feast of knowledge.

Thrandis was pleased with Rosen's state, and a smile of approval appeared on his solemn cheeks.

"Don't worry."

She handed Rosen three papers.

"It contains some prerequisites, such as the classification of spells, the meaning of the symbols of various advanced spells, and so on."

"You take it and read it first. When you're done, tell me. ”

Rosen took the manuscript with both hands and read it carefully.

'Neutral and polar, natural and logical, standard and extraordinary, and spell star....... Well, it's pretty finely divided. ’

That's what these symbols mean, and I'm so miserable. ’

He looked at it carefully and kept it in his mind.

Even without the aid of an adventure journal, Rosen's memory is quite good.

It can't reach the level of memorization, but after reading it a few times, it will be memorized.

Three pages of the manuscript wasn't much, and after about half an hour, he had it firmly in his mind.

He said respectfully, "Mentor, I'm done." ”

Thrandis glanced at him and asked, "What is the difference between natural spells and logic spells?" ”

"Natural spells have real objects at the heart of spell drives. Logic spells are driven by pure logical imagery based on mathematics. ”

"Where's the spell star?"

"Refers to the requirements for multi-line operations, one line is equal to one star."

"Is the more stars the better?"

"Normally, the number of stars only represents the complexity of the spell, but high-star spells tend to be more powerful."

"What about this mana formula?"

"That's what it means......"

"Not bad."

Thrandis stopped his expedition.

"Now, I'm going to start with the lowest level of principles and explain to you a neutral, logical, three-star spell 'Missile Technique'."

"You have to listen carefully and master it as quickly as possible, because I don't want to waste too much time on such a simple spell."

"Yes, Mentor."

Rosen was a little excited.

After months of pursuit, and many lives and deaths, he finally had to see the true face of the first official spell.

Thrandis entered a state of concentration, and as soon as her thoughts moved, a ball of light glowing with silver light appeared in the air around her.

The ball of light is about the size of a date, very bright, with well-defined borders, and has the texture of a solid crystal.

"It's a standard missile. Official mages can purchase spell books from the Mage's Guild for about 20 crowns. ”

"It's silver because it's dyed by my silver moon mana."

Rosen suddenly remembered the triple strike of missiles released by Cyrus.

Initially dark red, after absorbing the ash feathers, it becomes grayish-white.

As a result, he had an intuitive understanding of neutral spells.

Thrandis continued.

"Imagine the existence of a small ball with a diameter of one centimeter, and the ball is infused with extremely condensed power, controlling the ball to completely release the inherent power at the moment it hits the target."

It's very intuitive and easy to understand.

It's only a little more complicated than his self-created flying technique, and I can't help but feel that 'it doesn't seem to be difficult'.

Thrandis had been paying attention to the apprentice's expression, and smiled faintly at the sight of him.

"Missiles are indeed the simplest formal spells, but they are not something that a spell apprentice can take lightly."

"You can try to condense a missile according to the principle I said. Remember, just condense, don't throw it out. ”

Lawson nodded.

He tried to imagine according to the principle.

The thought moved, and the mana followed.

In the air a meter away in front of him, a perfect sphere with a diameter of one centimeter slowly emerged.

In the beginning, the sphere was just a slightly twisted cloud of air.

Gradually, the distorted air began to glow, the light gradually brightened, and the texture of the ball gradually became solid.

However, when the brightness and texture reach a certain level, anomalies appear.

No matter what Rosen imagined, no matter how much he tried to activate the mana, the orb in the air never achieved the desired effect.

It's like a pool.

He was filling the water on one side, but there was an outlet leaking on the other side, and the water was the same as the water entering and exiting, so the pool was never filled.

But the principle of the missile technique is obviously very simple, how can it fail?

"Alright, don't waste your mana, give up."

Rosen gave up his imagination, and the points of light in the air dissipated into a wave of heat, and made a soft 'poof' sound, like a deflated balloon.

"Why?" He immediately asked.

Thrandis smiled slightly.

"Because mana is also an objectively existing entity, with its own unique operating rules, mages can't do whatever they want."

"It's like a thousand-pound iron ball, of course you can try to lift it, but if you only rely on brute force and don't have the right way, then it's futile to try for a hundred years."

Rosen's eyes lit up.

Thrandis raised a finger, and the silvery-white ball of light flew over, flying around her finger with a whistle-like dripping sound.

"The ball is mana, and the condensed power in the ball is also mana. It is the mana that propels the ball to fly. The essence is the same. ”

"How to let one part of the mana restrain another part of the mana, and how to let one part of the mana control all the remaining mana. And how to ensure that the various parts of the mana do not interfere with each other. It's the meaning of the existence of the spell structure. ”

"I see!"

Rosen listened in fascination.

At this time, when I think back to the original creation of the mage musket, it was completely a mistake.

No matter how insane Thrandis behaved and how he disregarded worldly etiquette, at this moment, she was Rosen's most respected guide to magic.

Next, Thrandis began to explain to Lawson in detail the structure of the spell of the 'Missile Technique'.

To be honest, her class was not very good.

It's not that she's not responsible, it's that she's not very expressive.

She has a hard time expressing a subtle concept precisely, so she likes to use a lot of obscure words.

Occasionally, he will sink into his own thoughts and be unable to extricate himself, so that he will be cold for a long time.

Fortunately, Rosen has a good brain, is well-informed, and does not have the shyness of a young man.

He dared to ask.

As soon as he encounters something he doesn't understand, he will ask to the end to ensure that he understands correctly.

Time passed minute by minute, and more than an hour passed in a blink of an eye.

Suddenly, Rosen heard two streams of information flash through his mind.

'Mastering Spells: Missile Technique, included in Lawson's Book of Spells. ’

'Gaining full knowledge of a full-fledged low-level spell, the new program Spell Virtual Machine has been activated. ’

The first news was normal, but the second news made Lawson's heart jerk, and he was about to check it when he heard the voice of Thrandis.

"Do you understand?"

Rosen stared down at the floor, silent, as if thinking, but in fact, he was looking at the desktop in a sea of consciousness.

Sure enough, there was a new gear-shaped icon on the table, called "Spell Virtual Machine", but now is obviously not a good time to check it out.

Suppressing the intense curiosity in his heart, he opened "Rosen's Spell Book" again.

There's an extra page in the spellbook titled 'Missile Technique'.

Projectile (standard neutral logic three-star spell)

Ability Power: 10.1 (Intermediate Elementary)

(Note: Due to the caster's ability to quantify, spell power will also be quantified.) ）

Spell Evaluation: The most basic but also the most practical formal spell, very easy to master and powerful to be reckoned with. Because of the caster's high mana strength and high polarity, the power of the spell is greatly enhanced.

Maximum cast time: 0.5 seconds.

(Note: This limit is determined by a combination of the upper limit of mana flow rate and the spell structure, and cannot be optimized by increasing cast proficiency.) ）

Max Cast Range: 50 meters.

Mana Cost: Very high.

(Note: The user's current mana can only unleash a maximum of two Missile Spells.) ）

After a few quick glances at the spell book, Rosen nodded.

"Mentor, I understand."

Enlightenment flashed through my heart.

"At the beginning, Cyrus was a low-level, and after using three missiles in a row, and still had the energy to cast other spells, I could only throw two missiles, which means that I haven't reached the low-level yet. ”

At this moment, Thrandis's voice came again.

"I've finished talking about the missile technique, what else do you want to ask?"

Rosen has long had a lot of problems.

"Mentor, can I try to release a missile now?"

Thrandis did not hesitate to veto.

"Not now! You'll have to wait until you've mastered the hands of the three mages before you can safely release the missiles. ”

Three-star spells require the ability to master the fine operation of the three lines.

And without the assistance of the spell book, Lawson's current level is about 2.5 lines, which is indeed a little worse.

In this case, he did not insist on it, but asked a second question.

"Why is it that the diameter of the imaginary ball is one centimeter, but half a centimeter is not enough? Or can't a 10-centimeter branch? ”

Thrandis narrowed, "Good question."

"Spells can be modified, but they must be done with great care."

"Because under every formal spell, there are countless white bones buried."

"If you fail, you're likely to be a new skeleton. And when you successfully improve a formal spell, you have an extraordinary spell of your own. ”

Speaking of which, it's almost nine o'clock.

Thrandis said, "Alright, that's all for today's lesson. You go to rest. ”

"Mentor, I also want to ask, how clear is the figuration of the sea of consciousness before it can be considered a lower rank?"

Thrandis squinted and smiled.

"Don't worry, when the time comes, you'll know."

The answer wasn't very satisfying, but Thrandis was already yawning.

Curious about the new features on the desktop, Lawson bowed and turned to go downstairs.

When he reached the door, the words of Thrandis came from behind him.

"Rosen, the most taboo thing to learn spells is to be in a hurry, to move forward steadily. You must keep this in mind! ”
