There are quite a few crowns in the treasure, but most of them are exaggerated and very heavy.

Green searched for a long time in the jewel box, and only then did he find one that he was satisfied with, the size of a headdress, but without lacking a royal demeanor.

Placing the crown on Mary's head, Green touched his chin and looked at it for a moment, feeling that something was missing.

So he glanced down and saw a golden cane, and his eyes lit up.

Smiling, he handed the cane to Mary, and Green patted the ash on his hand with satisfaction.

Sure enough, men are children who don't grow up!

Mary gave Green a funny look, and then said, "Alright, my knight, can we go back?"

"Where my king's heart desires, we wait for the sword to point!"

With a clang, Green drew the sword at his waist and waited for Mary to hold the hem of her skirt and take his arm before striding towards the outside of the cave.

It's just that when they walked out of the cave and saw Pippi, Meow, and Pikachu looking at them stupidly, the two of them immediately laughed together.

The angry wind that followed behind looked helplessly at the sky, what a bunch of naïve guys!

"Xiao Linzi, you are so happy, it seems that there are a lot of treasures found!"

"Haha, no more, no less, at least twenty tons of gold!" Green grinned.

"Isn't it twenty tons of gold?" Nebel's voice was particularly disdainful, "I'm not targeting you!

Why don't you go and catch sheep on the green grassland?

Twenty tons of gold can be minted into 10 million crowns of 2 grams of gold, and the purchasing power of a gold coin is quite strong in the world.

"Xiaolinzi, don't you believe it?" Nebo snorted coldly, "See those ores under Pippi's feet?"

Green nodded.

Just when Pipsqueak was stupid, a few stones fell out of his mouth, and he had already noticed.

"Pick up a piece and throw it up!"

There is something shimmering with a silvery sheen in the exposed parts of the stone.

After picking it up, Green glanced at it, and his heart couldn't help jumping, this is Mithril ore?

With a slight drop, the stone flew upwards and fell so slowly that it looked like a falling leaf.

Such a magical property made Green stunned on the spot, standing in place for a while, and then he reacted excitedly.

"Oh my God, this can't be the reason why this mountain floats in the sky, right?"

Nieber smirked, "Hehe, Xiaolinzi, superconducting ore at room temperature, you should understand the meaning of this." ”

Green certainly understands.

Even on the earth in the 21 st century, the best superconductors can only work at room temperatures below minus 200 °C! As for superconducting materials at room temperature, that is an insurmountable technical problem.

And now Nebel has found one of them.

Superconductor has zero resistance, zero loss, super diamagnetism, if a piece of superconductor is placed above the permanent magnet, it will levitate, and the maglev train is using this principle.

So, below this suspended mountain, there is a huge permanent magnetic field.

But what's the use of this thing?

Build a city in the sky? Green thought for a moment, and suddenly startled himself.

"Don't always try to make big things, young man, do you know how difficult it can be?" Nieber scoffed, "We're going to start with some easy things. ”

"For example?" asked Green, curious.

"Set up a superconducting antenna on the Feixiang as a relay station for the fairy dragon's wireless waves to achieve long-range communication. This way, you don't have to worry about the Recon Dragon Knight flying too far to send back the message in time. ”

......

Compared to the treasure, this amazing superconductor ore at room temperature is indeed a bonus.

However, he felt that the biggest discovery this time was neither a treasure nor a superconducting ore, but a mysterious place in the Devil's Sea.

They just looked in one direction, around the outer ring, and found so many amazing things. So if you can go deep into the interior of the Devil's Sea and explore the entire Devil's Sea, you may be able to discover more secrets.

But Green didn't dare to take any more risks.

The compass was unusable, the sky was always hazy and it was impossible to tell where the sun was, and this was the maximum they could go into.

Everything in the Devil's Sea was unknown, and he didn't want to get lost in it.

Picking up a few pieces of ore and packing them in his backpack, Green climbed onto the dragon's back and made Pipsqueak leap down the mountain.

Finally, they circled the Suspended Mountain for another week.

The whole mountain is about one square kilometer in size, and when you look up from the foot of the mountain, it looks like a huge land floating in the sky, and through the light mist, you can see other suspended mountains looming in the clouds...... Such a suspended mountain is not just one in front of you.

When you have a chance in the future, you must explore this place well, Green touched his chin and made up his mind, and flew back with Mary towards the route he had come.

Once again, they encountered the formidable gargoyles, but this time before they could take to the skies, Green blew the dragon flute.

Just like last time, the huge monster immediately turned into a statue motionless when it heard the sound of the flute.

It's just that one thing that shocked Green was that the gargoyleyle that had broken one leg by Pipsqueak had grown a "new leg"!

"Neb, do you know what's going on?"

Green knocked on the silver gleaming metal of the dragon's legs.

"It's a metal golem with self-healing powers, and the petrified skin on the outside is just a camouflage for them...... And their creators are not supposed to be native creatures of this world. ”

Green couldn't help but think of Nebel's original owners, the aliens who had been to this planet.

It's just that these gargoyrts shouldn't have been made by them, otherwise Nebel wouldn't have known about it, so who else?

Green picked up the black dragon flute in his hand and glanced at it.

It should be very possible that the Dragon of Despair created these puppet lifeforms to protect this mysterious sea, and it must have a purpose.

It's just that what this purpose is, Green can't guess for the time being, but he thinks it's better to get out of here as soon as possible.

Such a terrifying existence as the Dragon of Despair, whether it is myth or reality, whether it will awaken in the future or not, is not something that an ordinary person like him can provoke.

But as the saying goes, support the bold to death, starve the faint to death.

Since the treasure has been found, it must be shipped out, and the superconducting ore must also be mined and studied, as for these stone dragon puppets, Green even wants to take them back and study them well.

However, he tried, and these intelligent monsters could not understand any other commands except for being able to stand still or attack with the sound of the flute, so they had no choice but to give up.

When Green took Mary through the border of the Devil's Sea and returned outside, he thought he would hear the earth-shattering cheers, but he didn't expect to see a sea filled with gunpowder.
