"The magic array has a magnetic field, and the spirit pattern also has it, and the spirit pattern itself is drawn by the magnetic field pattern I see from the ability of the ability, everything has a magnetic field, and the magnetic field of a thing is not necessarily very uniform, and the mushroom is the only two materials I have seen with an evenly distributed magnetic field, so I chose to use it to carry the magic array." Song Yi explained why pure mushroom materials must be used.

"What's the other thing?" Researcher Wang understood the reason, he didn't expect that there were so many doorways, and he was also curious about another material.

"It's a jade bamboo, the mutated bamboo that everyone uses to hold water." Song Yi replied.

"Yuzhu, is that Yuzhu in the big bamboo forest in the east of our city?" Researcher Zhou also opened his mouth in surprise, "Then why don't you use jade bamboo as a material, the material of bamboo is obviously harder than mushrooms." ”

"Yuzhu may be a specialty of J City, but the mutated bamboo I have encountered in other places before is not like this." Song Yi spreads hands ┓(')┏.

"Isn't the magnetic field of a metal different?" This time it was Professor Zhao who spoke up, and he was the leader of the team in charge of this aircraft project.

"The magnetic field of the metal is the same, but it is a single metal, those alloys, although they seem to be perfectly fused, but in fact, there are still some places that are not completely fused, this subtle perception is very inconspicuous, it is no problem to use it to make a machine or something, it is no problem to draw a magic array, but it is not possible to engrave a magic array, and the metal does not contain a little impurity when it needs to be extracted." Song Yi said.

At least for now, Song Yi finally understood why those monk refining weapons had to come one by one, because they needed to constantly refine the fusion materials to make them flawless in order to either inscribe or enter the formation runes.

Or like Western magic enchantment, directly inlaid with enchanted gems, magic crystals and the like on some materials.

"So that's all we can use?" Professor Zhao frowned.

"It's not that it can't be used at all, but you need to make another thing and inlay it, such as something like a array plate, but this thing will be more demanding, and it can't be used as a material like mushroom and jade bamboo." Song Yi said.

W City has also tried to use other materials, and then use mushrooms to make a formation plate to carry the magic array, and then inlay it on the aircraft, but it can't drive the entire flying machine at all.

After Song Yi checked it, he found that the energy magnetic field of those array disks could not completely cover the entire flying machine at all, and the materials made of mushrooms could extend the magnetic field of the magic array due to their own ductility.

"The carrier you are talking about, is this okay?" Modern people, even the older Professor Zhao have seen a lot, and after listening to Song Yi's words, he walked to the cabinet on the side, opened it and took out something from it.

"What is this?" Song Yi took a look at it and found that the magnetic field of this thing was flat and powerful, and like a mushroom and jade bamboo, the magnetic field was uniform.

"This is an ore found by the exploration team in the mountains to the west, and after identification, it is known that it is an energy mine, named magnolia, but the energy in it cannot be absorbed by humans, and we have shown that we have not found a way to guide it out." Professor Zhao replied.

"I think I can try." Song Yi said: "Its magnetic field is very peaceful and uniform, and it feels very suitable for inscribed formations as carriers." ”

"Get Shen He." Professor Zhao said to the assistant next to him, and the man answered and went out, bringing someone in after a while.

"Professor Zhao." Shen He came over and said hello to Professor Zhao.

"You carved the magic array onto this magnolia stone." Professor Zhao said, "Let's just use the anti-gravity levitation flying magic array." ”

The anti-gravity levitating flying magic array, originally only had the ability to resist gravity, and other magic arrays were applied, but later, with the help of researchers from the research institute in W City, it was upgraded and improved, adding suspended spirit patterns and flying spirit patterns.

"Okay." Shen He nodded and began to engrave the magic array, his ability is the inscription, it is said that he was once the inheritor of the miniature carving, and after the ability awakened, it was also related to this.

Thanks to his ability, a whole piece of ore was quickly carved into a round plate, and then a magic circle was soon engraved on the round plate.

Song Yi glanced at it and said with a smile: "The magic array engraved on this ore doesn't even need magic potions to fill it. ”

"Is this something that can be mounted directly on the aircraft?" Professor Zhao asked.

"It should work." Song Yi nodded, "But this flying machine can't do it." "This flying machine has a magic array engraved on it, although it is useless, but it is a magic array in the end.

"Then you'll have to try it with the old flying machines." Professor Zhao said that they only have this one new work so far.

"Yes." Song Yi thought for a moment and nodded, so the group changed places and came to another laboratory, where they were studying how to make those scrapped flying machines fly.

Professor Zhao explained the intention, and they were also very cooperative, if their experiment was successful, then these flying cars could also be used, and there was no need to scrap them, although even if they could be used, they would have to make big changes inside, after all, human beings are now so much smaller.

Under Song Yi's guidance, they installed the array disk in the cab of the aircraft, and after injecting the ability, the magic array was activated, and an invisible energy quickly covered the aircraft, and then floated.

"It's moving, it's flying." The people below see it and immediately notify the people inside.

"It worked." Professor Zhao was very satisfied.

"Well, the magnetic field can completely cover the entire aircraft." Song Yi nodded.

"That should be fine, this ore, although it contains energy, but it can't be channeled out for use, but now it's useful, and that mine is quite large, it should be used for a lot of time." Professor Zhao said with a smile.

After the problem was solved, Song Yi was ready to leave, "Since the problem here is solved, then I will go back." ”

"Yes, I'm sorry for you, we'll credit your account directly." Professor Zhao thanked him.

"Okay, yes, if I want to buy that." Song Yi waved his hand and left.

When he went back, Song Yi also saw Uncle Song, he didn't notice Song Yi, and was discussing something with his colleagues next to him, Song Yi only vaguely heard words like potions, which should be discussing the production of potions.

Song Yi didn't go up to say hello, and left the dungeon directly, coming to the surface, only to find that next to this exit was a large building that had been built, and it was surrounded by larger buildings.

It can be seen that these are not housing, it looks more like a factory or something, Song Yi took out the flying wings and prepared to go back, but as soon as he flew up, he was stopped by someone: "Hello, flying is prohibited here." ”
