Human beings have become smaller in the last days

"The magic circle has a magnetic field, and so does the spiritual pattern. The spiritual pattern itself is drawn from the magnetic field patterns that I saw from the powers used by superpowers. Everything has a magnetic field, and the magnetic field of a thing is not It must be very uniform. Mushrooms are the only two materials I have seen with evenly distributed magnetic fields, so I chose to use them to carry the magic array." Song Yi explained why pure mushroom materials must be used.

"What is the other thing?" Researcher Wang finally understood the reason. He didn't expect that there were so many ways to do it, and he was also curious about another kind of material.

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

"Polygonatum odoratum, the one in the large bamboo forest in the east of our city?" Researcher Zhou also said in surprise, "Then why don't we use Polygonatum odorifera as the material? Bamboo is obviously harder than mushrooms."

"Polygonum japonicus may be a specialty of City J. The mutated bamboo I encountered in other places before is not like this." Song Yi spread her hands┓(`)┏.

"Are the magnetic fields of metals different too?" The person who spoke this time was Professor Zhao, who was the leader of the aircraft project team.

"The magnetic field of metal is the same, but it is a single metal. Although those alloys seem to be perfectly integrated, there are still some places where they are not completely integrated. This kind of subtle detection is very inconspicuous and is used to make machines and so on. It's no problem, and it's no problem to draw the magic circle, but it's not possible to engrave the magic circle, and the metal needs to be extracted without any impurities," Song Yi said.

At least that's the case for now. Song Yi finally understands why the monks in the novel have to refine their weapons one by one, because they need to constantly refine the fusion materials so that their fusion can be perfect before they can be engraved or entered into the formation. French runes.

Or, like Western magic enchantment, enchanted gems, magic crystals, etc. are directly inlaid on some materials.

"Then we can only use this?" Professor Zhao frowned.

"It's not that it can't be used at all, but it needs to be made into something else and inlaid on it, such as something like a formation plate, but the requirements for this thing are relatively high, and it cannot be used by materials like mushrooms and polygonatum." Song Yi said.

W City has also tried to use other materials, and then use mushrooms to make array disks to carry the magic array, and then embedded them into the aircraft, but they were unable to drive the entire aircraft at all.

After Song Yi checked it, he found that the energy magnetic field of those array disks could not completely cover the entire aircraft, but the material made of mushrooms could extend the magnetic field of the magic array due to its own conductivity.

"The carrier you are talking about, is this okay?" Modern people, even the older Professor Zhao, have read a lot of novels. After listening to Song Yi's words, he walked to the cabinet nearby, opened it and took out something.

"This is this?" Song Yi took a look and found that the magnetic field of this thing was flat and strong, and like mushrooms and polygonatum, the magnetic field was uniform.

"This is a kind of ore discovered by the exploration team in the mountains to the west. After identification, it was found to be an energy mineral and named magnolia. However, the energy inside cannot be absorbed by humans. We have also shown that we have not found any way to guide it out. Method." Professor Zhao replied.

"You should try it." Song Yi said: "Its magnetic field is very flat and uniform, and I think it is very suitable for inscribing formations as carriers."

"Fetch Shen He." Professor Zhao said to the assistant next to him. The man responded and went out, and soon he brought someone in.

"Professor Zhao." Shen He greeted Professor Zhao after he came over.

"You engrave the magic array on this piece of magnolia stone." Professor Zhao said, "Let's use the anti-gravity levitation flying magic array."

The anti-gravity levitation and flying magic array originally only had anti-gravity capabilities and was applied to other magic arrays. Later, with the help of researchers from the research institute in W City, it was upgraded and improved, and levitating spiritual patterns and flying spiritual patterns were added. "Okay." Shen He nodded and began to carve the magic circle. His power is carving. It is said that he was once the inheritor of the miniature carvings, and it was related to this after the power was awakened.

Under the influence of his supernatural power, a whole piece of ore was quickly carved into a circular plate, and then a magic circle was quickly engraved on the circular plate.

Song Yi took a look and smiled: "The magic circle engraved on this kind of ore doesn't even need magic potion to fill it."

"Can this be installed directly on the aircraft?" Professor Zhao asked.

"It should be possible." Song Yi nodded, "But this aircraft cannot." This aircraft has a magic array engraved on it. Although it is useless, it is a magic array after all.

"Then we can only try it with the previous aircraft." Professor Zhao said, this is the only new one they have made so far.

"Okay." 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 aircraft fly.

Professor Zhao explained his purpose, and they were very cooperative. If their experiment was successful, these flying cars would be usable and would not need to be scrapped. Although even if they were to be usable, major changes would have to be made inside. After all, human beings have become so smaller now.

Under Song Yi's guidance, they installed the array disk in the cockpit of the aircraft. After injecting supernatural power, they activated the magic array. An invisible energy quickly covered the aircraft and then floated.

"It's moving, it's flying." The people below immediately informed the people inside when they saw it.

"Successful." Professor Zhao was very satisfied.

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

"That should be enough. Although this ore contains energy, it cannot be channeled and used. Now it is useful. Moreover, the mine is quite large, so it should be able to be used for a long time." Professor Zhao said with a smile.

After the problem was solved, Song Yi was ready to leave, "Now that the problem here has been solved, I will go back."

"Okay, sorry to trouble you, we will deposit the reward directly into your account." Professor Zhao thanked you.

"Okay, by the way, if I want to buy that kind of thing." Song Yi waved his hand and left.

When going back, Song Yi also saw Uncle Song. He didn't notice Song Yi and was discussing something with the colleague next to him. Song Yi only vaguely heard the words "potion", and they should be discussing making potions.

Song Yi did not go up to say hello, but left the underground city directly and came to the ground, only to find that next to the exit was a large building that had been built, and was surrounded by larger buildings.

It can be seen that these are not houses, they look more like factories. Song Yi took out the flying wings and prepared to go back. As soon as he took off, he was stopped by someone: "Hello, flying is prohibited here."
