The research notebook left by Wensell records in detail all kinds of contents about the magic runes, from the initial research ideas, to the research process, to the drawing method of the runes, and finally the use of the runes, and so on.

It was only after reading this notebook that Rocky had a real understanding of the magic runes.

This is indeed a great invention!

As for Winsell, he is a true genius!

This Wensel not only invented the magic rune, but also improved the entire magic rune system by himself, and even divided the rune into levels.

According to his division, there are six levels of magic runes, the lowest level 1 and the highest level 6, and the capacity of the runes will continue to rise as the level increases.

And this classification of grades corresponds to the size of the Philosopher's Stone, because the Philosopher's Stone is also divided into six levels: miniature, small, medium, large, super-large, and special.

According to Wensel's calculations, the first-level runes correspond to miniature magic stones, but the magic energy contained in them is only half of that of miniature magic stones, which means that two first-level runes are equivalent to a miniature magic stone.

The second-level runes correspond to small magic stones, and in the same way, three second-level runes are equivalent to a small magic stone.

The third, fourth, and fifth level runes also have a similar conversion method.

From this conversion, it can be seen that a single rune cannot be compared with a magic stone of the same level in terms of capacity, which Wensel also mentioned in his notes.

But he also emphasized in his notes that the advantage of the magic rune is not the capacity, its real advantage is the size!

The essence of the Philosopher's Stone is a stone after all, and this essence makes the Philosopher's Stone congenitally have a huge flaw, that is, it is too large.

Even the smallest miniature magic stone must be the size of a bottle cap, which is already the smallest volume that a magic stone can reach, no matter how small it is, it will not be able to carry magic energy, it will only become a waste stone.

But what can the miniature magic stone do? I'm sorry, it can only be used in daily life, such as providing energy for magic lamps, and nothing else, the micro magic stone contains too little magic energy to make magic equipment at all, let alone inlay it on the air magic armor.

If you want to make magic equipment, you need at least a small magic stone, but how big is the small magic stone?

Egg-sized!

Each small magic stone is equivalent to an egg-sized stone, so just imagine how many small magic stones can be embedded in a piece of equipment, even if it is a large piece of equipment such as a shield or plate armor?

Not to mention the medium-sized Philosopher's Stone and the Large Philosopher's Stone, which are simply too large to be used to make equipment, as far as Rocky knows, only a complete set of Empty Demon Armor can barely inlay a medium-sized Philosopher's Stone, and there is no other equipment that can inlay such a large stone on it.

Therefore, even if the medium-sized and above magic stones contain a lot of magical energy, they can only be used in magic cannons or floating ships due to their large size.

This is the birth defect of the Philosopher's Stone, it is too large.

And the advantage of the magic rune is precisely here.

What is a rune? It's a symbol!

How big is the rune? The rune has no volume at all!

As long as there is space on the target, the runes can be drawn on it, and you can draw as many as you want, so it can be said that there is almost no limit to the use of magic runes!

That's why Rocky was able to cut off the magic sword with a rune sword in the first place.

Although the severed magic sword was also inlaid with small magic stones, due to its large size, only two small magic stones were inlaid on the hilt of the long sword, and its power was naturally limited to a certain range.

On the other hand, the rune sword left by Wensell did not have this restriction at all, and Wensell also specifically mentioned the rune sword in his notes, and emphasized that all the rune swords drawn on the rune sword were first-level runes!

You must know that the magic energy of two first-level runes is equivalent to a miniature magic stone, and the magic energy sword is inlaid with small magic stones, and it is still two.

But even so, when the first-level runes with such a low magic energy content reached a certain number, the power of the burst directly exceeded that of two small magic stones.

This is exactly the original intention of Wensel's research on the magic runes, using quantitative changes to cause qualitative changes!

"Hoo ......"

Lodge took a deep breath as he closed his research notes and went through what he had seen.

By reading the contents of his notebook, he finally understood the greatness and subtlety of the magic runes, and at the same time he was in awe of Wensel.

Wensel is definitely a master, this is not only reflected in his ability, but also in his determination to resist demons, this determination even made him give up the opportunity to escape from the sky city, you must know that a master like him would definitely be sent to the sky in the first batch back then, but Wensell did not go.

But it was his stubbornness that led him to invent the magic rune, which Wensell recorded in detail in his notes, that he studied the magic rune alone for ten years after everyone else fled to the sky, and finally succeeded in researching the magic rune.

It was a full ten years, and what kind of perseverance did it take for Winsell to persist for ten years and finally complete his great invention.

This kind of perseverance has to make Rocky feel admired.

Now, the magic rune has finally seen the light of day and fallen into Rocky's hands, so not only for himself, but even for Wensel, Rocky will carry forward the magic rune.

As for the drawing technique of the runes, Wensell also recorded in detail in his notes, if you want to draw magic runes, you must use magic power, and the higher the level of the runes, the higher the requirements for magic power.

According to the notes, the first-level magic rune is very simple, and the first-level mage is enough to complete it after mastering the method, but when the level of the rune reaches the second-level, the requirements for magic power are relatively high, and it takes at least a third-level mage to complete, and as for the third-level rune with a larger capacity, it takes at least a sixth-level mage to draw successfully.

Such strict requirements in terms of magic power gave Rocky a bit of a headache, because he was only a first-level mage.

But fortunately, this kind of thing is not absolute, he is only a first-level mage now, and he can be upgraded in the future! Even if he can't reach the highest level, he can still hire someone to draw runes.

So although he had a headache at this point, he wasn't very worried, and besides, he could learn the first-level runes now, which was enough.

You must learn the first-level runes as soon as possible!

After reading the research notes, Rocky already had a clear goal for what he wanted to do next, which was to learn the first-level magic rune as soon as possible!
