Harry and Ron have been sitting around foolishly for more than half an hour.

Before, they were still struggling to sleep, but now they feel that they have reached the point where they can fall asleep on the spot as long as they give a pillow.

To be honest, at the beginning, they were also very curious about Maka and Hermione's experiment - Hermione developed the skill of constructing magic text array on stone plates with curved surface, and made a round shield with defensive array with stone.

According to the discussion between Maka and Hermione during the test, the effect of the array is to achieve the goal of defending against non physical magic to a certain extent through rapid interference with magic.

It has to be said that after several actual tests by Maka, the effect of the magic text array designed by Hermione is really very good. Even Maka's regular force beam, which controlled the intensity, failed to cause direct damage to the stone shield.

Unfortunately, the biggest problem now lies in its carrier.

So far, both Maka and Hermione have recognized that "stone" is the most suitable carrier for the effectiveness of ancient magic writing, because it will not cause too much loss to the magic flowing on its surface.

However, things made of stone are too heavy after all, and they are quite easy to damage. If we want to follow Hermione's original idea and make magic armor through this technology, we obviously need to solve many problems.

However, as Maka said - although Hermione's idea is not novel, it has great feasibility. It is a worthy application direction of ancient magic literature.

Of course, as for Marka, he also said that he didn't think of the use of curved slate, which is a little deliberately praising Hermione. After all, he had already made a spherical Rune array before. How could he not have studied the arc structure?

"Hermione..."

After staring at the stone shield cracked because it couldn't bear the operation of the formation for a while, Maka seemed to have figured out some new idea and suddenly said:

"I think maybe we can try the production of 'stone powder coating' - if we first make the armor with magic pattern array from metal with both plasticity and strength, then apply a special stone powder coating on the surface and outline it with magic ink..."

As she spoke, Maka couldn't help shaking her head.

"Forget it," he said. "No matter how strong the ordinary metal is, it can only bear the operation of the magic text array. This application may be valuable in other aspects, but there is still a big problem in making armor."

"... Hermione, I'll get you some metal shields later. You can try to do it according to my idea just now. As for armor, put it aside for the time being!"

Considering that the magic of those physical attacks can not be resisted by a set of armor, Maka's personal idea is actually based on the direction of Rune wizard robe. If one day we can conquer the array structure technology on the cloth, it will be a huge leap.

So, after encouraging Hermione a few more words, he put all this aside for the time being and turned to look at Harry and Ron.

"Sorry, you --"

Just as she opened her mouth, Maka saw that the two guys had dozed off shoulder to shoulder, and even Ron's mouth had a glimmer of glittering saliva.

"Well, what are they doing here?" Maka said curiously.

Hermione, who was packing the slate, shrugged her shoulders and didn't look back into the tunnel:

"They... Must be unable to sleep. They want to go out for a walk, and then they happen to hear something on our side!"

"Maybe! Then don't wake them up. They seem to sleep comfortably."

Maka smiled, then lifted the wand in her hand and waved it, directly turning the chair they were sitting in into a bed.

Hermione glanced at them at last, then waved to Marca and said:

"Then I'll go back first. You... Certainly won't sleep yet? Remember to rest early!"

"Well, good night."

Maka nodded, stood where she was and watched Hermione leave the tent. Then she turned and walked to the other corner.

The crucible there was still steaming, but it was different from when he and Hermione came in at the beginning. Now the steaming medicine mist there had disappeared from the initial prickles, but became much softer.

He stood by and looked inside. He found that the liquid medicine had thickened and looked as if it had become half a pot of green magma.

"Well, it's almost ready..."

After a murmur, he simply sat down and seemed to want to wait for the moment when the preparation of the medicine was completed.

While waiting quietly, the necklace that cursed Dean Boehner quietly emerged in his mind.

I remember he made a judgment at that time and thought that the person who made the necklace was not Haier Bo, but someone else. In other words, they may have other enemies acting in the dark. It is only because Haier Bo's action is too strong that most people are unaware of it.

At present, although Haier Bo should not be able to continue his plan for a while, other conspirators hiding in the dark may appear.

"No," Maka could not help shaking her head, "if there were such a group of people, they should be more inclined to hide now... Or they are another group of men prepared by Haier Bo in advance?"

Maka likes to leave her behind, and halbo seems to like it. So, no wonder Marca thinks so.

"What trouble."

He smacked his mouth slightly, and he frowned and muttered.

However, no matter who or even several groups of people exist in the dark, what he has to do will not change. As far as the current situation is concerned, Haier Bo himself is still the biggest threat, and others are obviously secondary.

Therefore, it is urgent to come up with a means to deal with the devil as soon as possible.

With this in mind, Maka raised her hand and rubbed her temples hard - during the period when Haier Bo's plan deviated, he needed to seize the opportunity and try to regain the initiative, which was difficult but necessary.

Unknowingly, Marca fell into meditation again. His face with some dignity was blocked by the hand supporting his forehead, so that people could not see his complete expression.

For a time, there was silence in the tent, and only the gurgling sound of the boiling liquid medicine in the crucible continued, bringing out bursts of more sweet medicine fragrance.
