With some speculation, Ron began his quest for guardian runes.

The first thing he tried was the one he understood best, and was even close to trying to break down and explore the mysteries of the essence, which represented the 'amplification' derivative rune.

This rune can be said to be the rune that exists in most of his current magic, whether it is the Giant Wind Blade, or the Gale Slash, or the fire-based Flame Burst Technique.

Because it's in most magic, Ron knows it best.

"The guardian system derivative runes should also be divided into the core and the outer layer, the core corresponds to the basic rune, and it cannot be changed and does not need to be changed, what is changed is the structure of the outer layer."

Ron groaned.

His exploration of runes was no longer new, and he quickly figured out the initial direction, first resolving the core and outer areas of the guardian runes.

This part didn't take much of Ron's time, after all, there were references, and his mental power, speed of thought, and knowledge of magic were no longer what they used to be.

It took him about half a day to disassemble the basic runes of the guardian system.

Once the core area is isolated, the next thing to do is to use the core area as the base and change the structure of the outer area to create derivative runes that represent different meanings.

Spiritual power is energy, and the core area represents energy conversion, which can be compared to a generator, while the outer area of the base rune is the light bulb and wire, and the outer area of the derived rune is a more complex resistor, demodulator, and other messy things.

These are all things that Ron has already understood.

Syllable!

The newly condensed runes took shape in the air, and then collapsed.

Eternal runes are different from elemental runes, even if they hold an elven wand, they are condensed in the void, not inside the orb of elves.

"Well, it looks like the direction should be right."

Ron suppressed the faint impact of the rune collapse, and did not show any negative emotions due to failure, but nodded thoughtfully and continued to try.

Second......

Third ......

Even if you have a lot of knowledge and are sure that your path is correct, there are indeed runes that represent the meaning of 'amplification' among the derivative runes of the Eternity system, and the runes of the Eternity system that are more than ten times more complex are still not so easy to explore.

In half an afternoon, Ron had failed nearly a thousand times.

Because it was an eternal rune exploration, not a basic elemental system, Ron couldn't do the exaggerated speed of several times a second, tens of thousands of times an hour.

But this nearly 1,000 failures did not bring no progress, but made Ron gradually understand the difference between eternal runes and elemental runes.

Is it possible to directly put the 'amplification' shell of the elemental derived rune on the outside of the core of the eternal rune? The answer, of course, is no.

How can low-grade wires support ultra-high voltage currents?

It will burn out in an instant.

This is also the cause of the collapse.

What Ron needs to do is to strengthen this low-level wire and turn it into a 'wire' that is more endurable and can carry high-level energy conversion.

This is very different from more than half a year ago, when the first time to explore derivative runes, the lines were randomly changed and built, as if there was a world of difference, just like elementary school students randomly changing numbers one by one to test other people's account passwords, and computer hackers directly starting from the core to crack it.

The sky gradually darkened.

Ron rubbed his swollen temples and stopped trying.

"It's a world away from before."

Slowing down his tense spirit and throwing the runes behind him for the time being, Ron looked at the dim sky and couldn't help but speak with some emotion.

In the past, it was true, tens of thousands of attempts, and the accumulated experience was meaningless, but now, even if it is only nearly a thousand failures, he has accumulated a lot of experience.

He estimated that no matter how bad his luck was, every attempt would be a failure, and in another three or five days, he should be able to use enough knowledge and experience to find the right combination and explore the first derivative rune of the guardian system!

Back to the accommodation, the usual cooking.

Ron has never broken the habit of cooking with his own hands, for him, cooking is not a waste of time, but a small amount of time to relax in the 19 hours of practice every day.

Although Ron doesn't like to exercise his body, it's good to cook a meal and do it with his hands.

Nami used to cooking, and Ron was used to it, so he made two portions at a time.

Dining room.

Ron casually chatted with Nami about rune exploration and high-level magic, which made Nami participate in the discussion with great interest, especially when she heard Ron's knowledge of rune analysis, splitting and rewriting, etc., which made her want to participate.

It's a pity that her current mental power has not yet reached the level where she can release second-order magic without pressure, and naturally she can't talk about studying runes and exploring high-level magic.

But it also gave Nami a lot of motivation.

Originally, after mastering the second-order magic, because the purpose of continuing to cultivate spiritual power was just to adapt to the second-order magic, this made Nami not highly motivated, after all, even if she didn't adapt, she could use it.

But after chatting with Ron, it made her regain more motivation and start working hard again, which also made Ron, who has a magical imprint and spiritual connection with her, get a buff, although the gain is not large, but it still works.

Ron estimated that Nami would be able to gain 10 points of spiritual power through resonance, or if she underwent a spiritual transformation, he would be able to gain 1 point of spiritual improvement through resonance.

It's a pity that the other magic mark in his hand can't be decided for the time being, otherwise it would be very good to have two mark links to increase his resonance spiritual power.

After dinner, Ron resumed his practice.

"There is not much movement in the exploration of the guardian runes, you should be able to try to go to sea with the warship to do some tasks, and at the same time you can mix in some achievement points."

While practicing, Ron pondered that it would be better if he could try to achieve something while practicing.

Before, the movement of studying third-order magic was too great to go out with the warship, and even he was forced to leave the headquarters and go to the sea far away to cultivate, but now exploring the guardian runes is not a problem.

For Ron, time is too precious to make the most of it.

After all, he had to figure out everything on his own, and there were no ready-made magic books for him to learn from.

He didn't want to wait for himself to become a bad old man in his seventies and eighties before he could master the forbidden magic of the fifth order, that kind of scene was unacceptable when he thought about it.

Next.

Ron arrives at the barracks' office.

However, his application to go out on a mission with the warship was blocked, because he did not have the status of a trainee sailor, unless he flew all the way to the Chambord Islands before.

It's obviously impossible to fly all the way with a warship, let alone make it like a warship's accompanying escort, just saying that exploring runes while flying will affect some of your energy, which is something that Ron can't accept.

"Trainee Marine Soldier...... I actually have to ask the chief instructor for approval......"

After learning how to become a midshipman, the corners of Ron's mouth twitched, his relationship with Zefa, the chief instructor, was probably the worst in the navy now.

Looking for Zefa's approval to become a trainee sailor, I'm afraid I'll have to make a bunch of moths.

However, with his current strength, Zefa should have no reason to refuse approval, and he will directly apply for graduation if it is a big deal, which is nothing more than a little troublesome.

If Zefa could teach magic, Ron wouldn't mind recognizing a teacher and respecting his teacher, but Zefa forcibly wanted to take him to a detour, just like a foreman at a construction site forcibly teaching a top physics professor how to move bricks!

It is clearly impossible to reach a consensus.
