Gene is in great need of astral square crystals.

"With this star boundary square crystal, I believe I can restore the real transmission array technology!"

Gene packed up the star square crystal with red light, and now he felt that it was worth it.

Transmission array technology?

Donne smiled strangely. No wonder he was so eager for the star crystal.

This crystal born in the star world is a very stable space material. It is the best material for making space equipment, but more importantly, it is also the best core material of transmission array.

Gene has been trying to restore the transmission array technology, but the material of star square crystal is too rare. Even the whole silver city only has a piece the size of a baby's fist. Even if gene has all kinds of ideas, he has to save some use.

The piece that Donne pulled out is not only the cutting standard, but also the size of an adult's fist, and the purity is abnormally high. It can be called the best star square crystal. No wonder gene was so excited.

The materials of the star world are extremely rare in prandal, but for the true gods such as nisclair, these materials born in the star world are the most common. Therefore, Donne has a lot of inventory. To exaggerate, there are too many villas to build.

Donne's eyes turned and suddenly thought of another thing. He suddenly smiled, took out a star square crystal and put it on the table.

Gene looked straight. "Donne?"

"Do you want it?"

"Yes."

"Get something for it."

"What?"

Gene scratched his head and ears in a hurry. He couldn't think of anything else he could exchange for star square crystals. This thing can basically be regarded as priceless and can't be measured with gold coins.

Donne smiled and said faintly, "floating stone."

Pumice stone is not rare. There must be pumice stone on the pumice Island, but as mentioned before, because magicians are monopolized by the city of silver, and magicians who can dig pumice stone are also in the city of silver, so pumice stone is also one of the specialties of the city of silver.

Of course, Donne can dig, but he doesn't have that kind of American time to dig. This is not a game. He can buy what he can buy. It's easy and labor-saving.

"Pumice? What do you want that for?"

Gene was at a loss. To say that the pumice stone is useful, it is also useful. Adding the pumice stone or extracted pumice stone dust to other things can reduce the weight and increase the carrying capacity, but it is not very useful for them with space equipment. At most, it is a little useful for those businessmen - but they can't afford it.

And floating stones are also very common. There are those floating islands in the sky. He doesn't understand why Donne needs floating stones.

"Of course it works."

Donne smiled and threw the star square crystal and said, "the silver city guarantees to supply enough floating stones for Ellington. This star square crystal belongs to you. How about this deal?"

"Enough?"

Gene smiled bitterly: "what is enough? The price of star square crystals can't be estimated at all. The price of pumice stone is very cheap. If you convert it, even if it is filled with your Ellington, you can't exchange star square crystals."

"Then fill it up."

Donne was still smiling. "Just say whether to do this business or not."

"Do it! Why not!"

Gene gritted his teeth and agreed to come down. Anyway, it's not him to dig the pumice stone. As long as he sends a task in the silver city and rewards it with the qualification or points of Xingyue tower, a large number of magicians will be willing to dig the pumice stone.

"Good, deal."

Donne threw the astral square crystal to gene.

Gene put away the star square crystal, still couldn't resist curiosity: "can you tell me what you want those pumice stones to do?"

Donne smiled. "Make a car."

In Donne's view, other things in the world are very common, whether magic core or magic metal. In a magic dominated civilization, these things are normal, and their uses have been discovered, but people here ignore a very precious wealth.

That is the floating stones everywhere on the floating island.

In Donne's view, the pumice is a huge treasure that prandal has not yet discovered!

He can't even understand what kind of pumice stone is and why it has the characteristics of anti gravity, but this doesn't affect his use of pumice stone.

There is no pumice stone. If he wants to design a flying car, he can only find ways to mass produce the anti gravity magic array. However, the R & D strength of the magic Energy Engineering Research Institute is too weak. It can be expected that he will encounter great difficulties. Moreover, even if it is realized, the cost will be quite high. At least the magic metal as the substrate is indispensable.

But with pumice, this technical problem can be easily solved.

As long as the tires of the motorcycle are cancelled, replaced by pumice stones, the self weight of the motorcycle is reduced, and the jet holes at the bottom and sides are increased, the idea of motorcycle flying car can be realized.

Without the limitation of tires, the strategic significance of an all terrain single person riding tool can be imagined.

In addition, even flying cars can be realized.

These ideas are based on pumice.

"Car? Carriage?"

Gene was stunned for a moment and suddenly realized: "Oh, someone has done this before. It's very interesting and fast. It's a good idea."

Donne didn't explain much. When the flying motorcycle was born, he understood how different the "car" was from what he thought.

In addition, there is one more thing.

Transmission array technology.

After thinking about it for a moment, Donne finally gave up.

Gene can be trusted. He is a great and selfless hero, but it is because he is too great and selfless that Tang en has scruples.

The technology of the transmission array is now in his own hands. Donne can also ensure that the transmission array will not be abused, but if he really teaches gene, Donne can't guarantee whether gene will immediately disclose this technology or lay magic arrays all over the world.

If that happens, what will be the consequences of the current situation?

It can be predicted that there will be a lot of spies among various countries, and even a large number of assassinations against the heads of other countries. The situation will become more chaotic, and those cults and ambitious people hidden in the dark will take the opportunity to fish in troubled waters and stir up the pool more muddy.

This is very bad for Donne's development.

Therefore, considering the final situation, Donne decided to keep gene confidential for the time being, and then slowly release his technology after the situation is stable.

"I'll go back first and release the task to let those boys dig pumice stones."

After getting two star square crystals, gene couldn't wait to go back for the experiment. He found an excuse and slipped away. However, he had left those magic classics, which would not affect the opening work of the school.

Donne found Pamela and OLINA and asked them to visit the second floor of the library. Suddenly, Rao's gentle Pamela was surprised to see such a big source of magic.

"This is the area where students learn magic. No people are allowed to enter. I have set up a magic array around the magic source. They can't get close to it. You can rest assured."

Then Donne pointed to the magic classics on the surrounding bookshelves and said, "these are magic classics brought by Jean. There are learning methods from entry to gold level, and they also include level 0 to level 4 spells. It is enough for our college now. What you need to pay attention to is to prevent students from practicing magic they can't master."

"So much?"

OLINA was surprised: "Jean... Legendary hero Jean? Why did he bring these magical classics here?"

Of course OLINA knew Jean's neutrality, but now what he did violated it.

After thinking about it, Donne said with a smile, "maybe it's because he likes it."

Elia's talent is enough to let people build a magic school for her. It's not surprising that Jean would have this attitude.

Although OLINA is strange, she is also very surprised. With these magic classics, Ellington college can become the second silver city and the second magic paradise!

She could already foresee the unstoppable rise of Ellington.

After leaving OLINA and Pamela to register and sort out the magic books, Donne left Ellington college.

As soon as he got out of school, he met Elsa running in a hurry.

"Lord!"

Seeing Donne, Elsa shouted in surprise, "just looking for you!"

Donne smiled and asked, "what's up?"

"The Phoenix mercenary regiment is here. Their leader Cao is looking for you."

Elsa stuck out her tongue: "although we know each other, I stopped them outside because of your orders. Now they are waiting for you."

"Phoenix mercenaries? They're back from the underworld?"

Donne was stunned and followed Elsa to the outside of the city. At a glance, he saw Cao chatting with Depp and the axe king and Pat who had a strong sense of vision.

"Lord Donne."

Seeing Donne, Cao greeted him with a smile.

Donne shook his hand and looked at him suspiciously. "Why are you here?"

Cao said with a smile, "you forget we are mercenaries? Of course, where there is business, we will go."

"Business?"

Donne was even more confused: "what business?"

Cao laughed and said: "I heard that Ellington is independent and has fought against new king Gillard, so I think... You must need the strength of Phoenix Contact. As long as the price is appropriate, we will fight for you."

Donne suddenly realized that he was a little funny and said, "aren't you afraid that I'll lose? Even you will be involved."

Cao blinked and looked a little strange: "after the battle in the underground world, I don't think you will lose."
