Coming out of the temple and back in the carriage, Lawson sat upright in his seat and closed his eyes.

He stayed in the virtual machine, carefully examining the knowledge Alfroya had given him.

After reading less than three pages, his understanding of the polarity of mana had improved tremendously.

The contents of the book are as follows.

"Polarity comes from figurative visualization. Visualizing the sun is a flame-like polarity. Visualizing the sea is pure water polarity. ”

"Spells also originally came from figurative visualization. Visualizing a volcano is a fire spell. Contemplating the rivers and lakes is a pure water spell. ”

"It's a well-known fact that pure water mages can also cast fire spells, and sun mages, can also cast pure water spells. But the power will be greatly reduced. ”

"Why?"

"yes, why?" Rosen's curiosity was raised to the extreme.

There are some explanations on this issue in many spell books, but they are all general experiences.

It's half-guessing, half-guessing, unconvincing, and useless.

An explanation is given in the book.

"Because the so-called polarity, the essence is magic, a kind of natural magic that changes with the visual image.

Because it is constant within the soul, we call it an inner spell. ’

And normal spells, which appear outside the soul, are external spells. ’

'Obviously, the ultimate power of a spell is the result of a combination of internal and external spells. ’

The book then gives a mathematical equation for the power of the spell.

"That's the empirical math formula I've come up with after countless spells. There will be discrepancies in the transcendent spells, but under the transcendental, they are extremely consistent with the facts. ”

Rosen's eyes lit up.

"Tsk~ This is the real thing!"

Those explanations that never quantitatively, but only know qualitative wordplay, seem to be very bluffing to a rough sound.

But if you think about it a little deeper, you will find that the eggs are useless.

And quantitatively, it means that it is measurable. Given the formula, it means that reliable deduction can be made according to the formula.

This is the knowledge that is truly usable and can be built upon to move forward!

In front of true knowledge, Lawson gathered his full attention and continued to look down.

'As a rule of thumb, if the inner and outer spells complement each other, the final spell will be much more powerful, and vice versa. ’

Below, I will analyze the inner spell in detail, explaining how the inner spell works with pure mathematical logic as much as possible. ’

Next, there are large sections of experiments, and large sections of mathematical deduction based on the results of experimental measurements.

Extremely cumbersome, extremely rigorous, can easily go around the minds of ordinary people, but makes Rosen fascinated and can't stop.

All kinds of doubts about polarity in his mind are constantly being answered in the clearest way.

Looking at it, my heart moved, and I found the lack of this knowledge.

"The essence of the polarity of mana is analyzed very deeply, and the rules of magic given are also very beautiful, but the mathematical analysis process is a mess."

"According to this algorithm, the amount of computation is huge, and it seems to be fine, but in fact it is cumbersome, and it is not beneficial to solve the problem."

According to the earth, it is a lack of aura, and only knows death.

"Well, I'll streamline it."

Just as he was about to do it, the voice of the coachman Joey came: "Master, I'm home." ”

"Hmm~"

Rosen's mind was still immersed in new knowledge, and he responded vaguely, and got out of the car and walked into the Sunshine Building.

There was no one in the hall on the first floor, so I walked to the flower hall on the second floor, and when I walked to the staircase, I heard a slightly heated discussion on the second floor.

"Alice~ If it is a one-time use rune stone, then you can naturally set a spell lock to prevent cracking. But if it's a spell that has been reused many times, it's impossible to set a spell lock! ”

The voice was crisp, it was Gendrony.

She breathed in no breath and continued.

"There is an irreconcilable contradiction."

"When a mage repeatedly uses a magic weapon, he must charge the magic weapon with mana, and once the mana enters the magic weapon, the internal structure of the magic weapon will be completely exposed, and there is no secret at all."

"And if you use a spell lock to deny the mage's mana penetration, then you can't recharge it with mana, and you can't talk about reusing it."

When it comes to spells, Gendeloni takes them very seriously, and has no friends in her eyes.

It's almost exactly the same as Thrandis.

Thrandis's voice rang out.

"Jenny~Jenny~ Please note that you are talking about traditional magic weapons, but our purpose is to create new magic weapons, so you have to use your brain and let your imagination run wild."

Gendeloni's voice came.

"Alice, it's enough for one person to imagine freely, there must be someone holding the kite string, otherwise the kite won't fly."

"After all, we are not talking about pure spells, but alchemical spells that interact with matter, and we must keep our feet on the ground."

Hearing this, Rosen knew that the two of them had encountered difficulties in the anti-cracking of magic weapons.

Rosen knocked lightly on the door at the top of the stairs: "Two young ladies, can I come in?" ”

"Oh, Lawson is back~"

"Come in, come in~"

The voices of the two women suddenly became very enthusiastic.

When Lawson entered the flower hall, he found the two women sitting at a round table, and the table in front of them was full of scraps, and then there was still a trace of heated discussion on the white jade cheeks of the two.

"It seems that the two beautiful young ladies are in trouble."

Thrandis slouched back in his chair, a rare look of frustration on his face.

"This is a real problem, I hardly see any hope of solving it, I love~"

Rosen was not in a hurry, sat down in his chair, and asked, "Jenny, how did you do this with such an original magic weapon in the past?" ”

Gendeloni was an expert in this area, and she immediately said, "Then it depends on who created it." ”

"If it is the original creation of a civilian mage who has no power, then sell it to the nobles, or the mage guild, and make a hammer of money. In the future, you can also build magic weapons yourself and make money selling magic weapons. ”

"But because the principle of the magic weapon has been made public, it can't make a lot of money."

"And what if it's a nobleman?"

"If it's an aristocrat, it depends on whether it's a big nobility or a small nobility."

"The small nobles are only slightly better than the common mages, and when they sell to the mage guild or the big nobles, they can adopt the sharing model, earn more and longer, but generally not more than ten years, and the sharing ratio will not be higher than two percent."

"Then if it is a big noble, then a decree will be issued in the territory, strictly prohibiting refiners other than designated refiners from manufacturing and selling such magic weapons, then you can make a lot of monopoly money."

Rosen immediately thought of the problem.

"And what about outside the territory?"

"Outside the territory, it depends on your influence. How much influence you have, how much money you share. If there is no influence, then there is no money. ”

After a pause, Gendeloni continued to explain.

"Therefore, the original magic weapon has never been the most profitable project for refiners, the most profitable thing is actually exquisite craftsmanship."

"For example, if you have a magic weapon, both refiners can fight."

"But one is rough and easy to break, and the other is exquisite, stable and safe, so even if the price of the latter is twice as high as the former, there will still be a lot of people with materials and take the initiative to buy it."

Speaking of which, she looked at Rosen with envy in her eyes.

"For example, your craftsmanship has reached an incredible level, and after a long time, more magic weapons have been sold, and after you become famous, there will definitely be many people who will come to you to build magic weapons."

Rosen spread his hands: "But this is still craft money, not to mention the waste of time, and the upper limit is not high." ”

After all, a mage's energy and time are limited, even if it rotates 24 hours a day, it is far less refreshing and easy than others to help make money together.

So, the problem comes back to square one again.

Thrandis took his pen and tapped the table, his face determined.

"Therefore, the stable petrification technique that we spent a lot of money to make must have a spell lock that is resistant to cracking."

This is the wisdom of God that Lawson desperately obtained, if he is not locked, he is making a wedding dress for someone else.

Then it's better not to sell it.

Gendeloni's cheeks bulged, "But it's a dead end, Alice, you can't keep hitting your head on a dead end." ”

During this time, while listening, Rosen wrote "A Deep Investigation of the Polar Nature of Mana", two quill pens together, in duplicate.

After writing, he handed the manuscript paper to the two girls separately and panicked.

"This is the new knowledge I bought from the Mage's Guild along the way, and I think it might help solve this problem."

The two girls immediately buried their heads in the look.

When I saw it, I was deeply immersed in it.

Lawson didn't finish reading it, so he closed his eyes and continued to watch in the virtual machine.

From morning to evening, until nine o'clock in the evening.

Lawson already had the initial idea for a spell lock.

"Anna, Jenny, this article gives a deep insight into the polarity of mana."

"It can be seen that the essence of mana polarity is a spell, and it is a special spell that is almost pure and cannot be perceived by the subjective consciousness of the caster."

"Then, we can take advantage of the characteristics of 'ignorance' to build spell locks that can be recharged repeatedly and avoid being probed by other mages about the structure of the magic weapon."

Gentroni hadn't figured it out yet, she frowned in thought.

Thrandis already had an idea, and she laughed.

"My love, you mean, reconstruct petrification using the rules of inner spells."

"And because the mage can't perceive the fine structure of the inner spell, when charging and using the spell, naturally there is no way to know the structure of the magic weapon, let alone deduce the principle."

'Bang Da~'

Rosen snapped his fingers.

"Anna, it looks like we're going together."

Gendeloni also understood, and immediately asked a new question.

"But what if the other party takes the magic weapon apart and looks at it directly?"

Rosen smiled: "This is simple, we can use the same internal spell principle inside the magic weapon to bind a triggered and bundled charged disintegration technique."

"Once the artifact is destroyed, it will trigger disintegration, directly destroying the fine structure of the artifact."

Gendeloni nodded, "So it seems that the problem has been solved."

Rosen shook his head: "It's just that there are ideas, and the specific implementation is very difficult."

With that, he clapped his hands again.

"Okay, it's late, go to bed, and after we get up tomorrow, we'll work together to get the encrypted petrified magic weapon out!"

After a pause, he added

"For maximum support, it's best to be like runestone, which can be used by fools. Of course, I knew it wasn't possible, but I just had to go in this direction as much as I could. ”

With that, he got up and walked to the guest bedroom.

"Wait~"

Thrandis shouted, "Today I'm going to sleep with you, Jenny alone." ”

Lawson waved his hand casually and yawned: "No, no, no, you sisters sleep." ”

Jenny Lonnie's voice also sounded, weakly: "Rosen, don't let me make your husband and wife always separate rooms, I sleep in the guest bedroom today." ”

Alice's mana light and shadow came out: "I said, can you stop being so troublesome?" The bed is so big, sleeping three people is not crowded! ”

Anna paused, then nodded, "I'm okay with that." ”

Gendeloni pursed her lips, her cheeks flushed, but in the end she nodded, "I don't care." ”

It's not the first time anyway.

Rosen turned his feet and entered the master bedroom.

"Then I'll sleep first, I'm really tired today, don't toss at night."
