For wizards such as Ron and Hannah, who are not very talented, it is undoubtedly extremely difficult to improve their strength to be able to adapt to the current level of combat.

Even Maca obviously couldn't break away from the basic theories of magic.

However, even if there is no way to quickly increase their own magical strength, if they only want to strengthen their combat ability, they can still find a way to do so after a little thought.

For example, with the continuous practice of Maca, the whole system has gradually improved the rune array.

I remember that not long ago, Hermione had carved the Magic Stone Tablet in advance, and made . The members repeatedly practiced the arrangement of the queue, so as to show the brilliance of the magic array several times in actual combat.

Although it is bloated overall, and cannot be used stably due to the high level of accuracy, the potential is enormous.

When Maca saw the effect Hermione had shown him, she realized that if she eliminated all these defects one by one, she might be able to create a new magical world of epoch-making significance.

So after that, even though she had been busy, Maca had repeatedly found time to think, and even tried some improvements with Hermione.

And in the end, he still focused on the "material" that carried the rune array.

Obviously, although Maca's rune array is a new system created by himself, its structural principle is different from the ancient circular magic array, but presents a form similar to the circuit diagram.

In the final analysis, his rune array was originally derived from various ancient magic array remnants scattered in ancient documents, and all kinds of magic scripts and rule runes were no different from ancient magic arrays.

It can be said that the essence of the two is also the same.

Because of this, some of the fundamental drawbacks of the ancient magic array naturally continued into Maca's rune array system.

Among the many difficult defects, perhaps the most restrictive to the development of ancient magic literature is their carrier.

Due to the problem of the transmission of magical power, only natural stone can make the rune array run most stably and smoothly, and its carrying material is immediately restricted. And because of the inconvenience of the stone itself, the study of magic arrays has not really become popular even in the heyday of magic in ancient times.

But in today's age of Muggle science, even if Maca itself is not very familiar with it, it is often inspired by a lot of common sense.

Just like when he had Hermione and the three of them make the transferred rune arrays at Fort Blois, the rune cards he gave were the result of his research - he had created a natural stone powder paint that would allow the rune arrays to work stably on any sufficiently flat surface.

In this way, as long as Maca, who has already mastered all kinds of magic scripts and runes, can draw the originally complex and huge array diagram as much as possible on the surface of the item that is portable enough. Then even Ron, who is not very high in magic, can use them normally through special spells as long as they go through a series of exercises that are not difficult.

Right now, a few of them were trying to practice outside the courtyard, and Maca provided two light metal shields with arm armor.

"Hey! Ginny, don't stand over there - this shield is a little hard to control, don't hurt you! ”

It can be seen that one of the arm shields made by Maca herself is being put on Ron's left hand. The off-white coating of stone powder hides the metal's unique luster, and the surface is covered with a large number of delicate lines and symbols.

Especially on the round shield, which was not very large, the complicated array should have been quite large, but it was reduced several times under Maca's skill.

Obviously, this kind of thing is definitely impossible to mass-produce, because every character on it contains Maca's understanding of this kind of rule. To shrink so many runes to such an extent like Maca, I'm afraid there are probably not many wizards in the world who can do it at the moment.

But there is no way, the more you want to make the formation miniaturized and portable, the more you need to ensure that they will not be easily destroyed in actual combat through various formation combinations. In addition, it is necessary to add formations that are easy for ordinary wizards to use, and the protective and functional formations alone account for more than half of the entire set of formations.

Although Maca is already asking Hermione and Luna to try to learn the rules runes, at least for now, the kind of equipment that will be distributed to everyone will have to be made by Maca herself.

As Maca pondered if there was still a possibility of improvement, he saw Ron finally recite the incantation he had just taught. In the next moment, an incomparably brilliant blue-white beam of light suddenly shot out from the center of the shield on his left arm, heading straight for the jungle in the distance.

With a "click-la-la" freezing sound, the trees on the path of the pillar of light were frozen and shattered, and the place where they passed was even whiter.

Although the beam quickly dissipated, it still left an afterimage on everyone's retina, which faded quietly after a few moments.

"Maca! It's-"

Before Ron could finish speaking, he shook under the gaze of his friends, and then fell to the ground.

Seeing this, Maca couldn't help but shake her head slightly, and said to Ron who was lying on the ground:

"Who told you to activate the cooldown rules as soon as you came up! Didn't I want you to try the first spell of the Magic Shield first? ”

In fact, this is already the result of Maca nesting an amplification formation in the formation diagram, otherwise just this moment would be enough to deplete Ron's magic and spiritual power.

But at this moment, everyone saw Ron get up from the ground in embarrassment, and said tremblingly:

"Really...... Too...... That's great! ”

"Take off your arm shield and give it to Hannah, you come over and drink a bottle of potion and rest!" Maca shouted at him angrily, "When you're ready, go to Neville's side and carry the stone with him." ”

"Huh?"

Hearing this, although Ron had a reluctant expression on his face, he honestly handed over the rune arm shield to Hannah beside him, and then dragged back to the courtyard with heavy steps, and lay down straight against the wall.

Seeing that Ginny had brought him the potion, Maca turned her attention back to Harry in front of her.

To be honest, although rune equipment is indeed something that Maca is looking forward to, if it is said that the next thing that can bring him enough help must be Harry, who has the sword of Gryffindor.

You know, as far as Maca knows, the "rage" rune contained in her sword should be the most aggressive of all the branches of the Soul Rules.

In the face of the mighty Helbo, Harry's presence must be indispensable.
