Birthright...... The contract has been decided, Lin An asked about the situation of the demon source, and asked the dragon to lead the way for her, but the dragon hesitated for a while:

"You have to promise that you can't be able to get anything on my turf. ”】

"I don't think you figured it out yet."

"Although the Demon Source is regarded as a temporary lair by you, that doesn't mean it belongs to you, Lord Nirac - if you haven't forgotten it, now, I'm the true master of this place?"

Lin An glanced at the behemoth.

At first glance, the obsidian dragon did look amazing, but after looking at it for a long time, it didn't feel like anything - of course, most of it was because of the contract.

After signing the master-servant contract, the dragon's dragon power was no longer able to influence Lin An.

On the contrary, because of the relationship between the master and servant contract, when Lin An casts the coercion of spiritual power, it will also have a part of the effect of dragon power, even if it can't intimidate the beasts like a dragon, but generally there will be no powerful demonic beasts running to trouble her for no reason.

["No, no, those hedrons are mine!"] You can't take it away! ”】

The black dragon stood in the way of Lin An and roared loudly.

"Hedrons?"

Lin An was surprised, she realized that she might have missed something.

The expression of the dragon face in front of him changed a little, but unfortunately, except for a few very obvious expressions, Lin An couldn't understand what those muscle changes represented.

"Don't try to hide anything from me, you know, you can't stop me."

Lin An clasped his arms, "Give you a chance, if you're honest, maybe I can consider your request." ”

The dragon's mouth was shut, and the dragon's eyes glared at the boss.

Really.

Even without the guidance of his parents, the dragon's instinct to protect treasures is innate.

"Speaking of which, I forgot one thing."

The huge crystal yellow dragon pupils glared at Lin An, and Lin An said to himself:

"The gem dragon is said to feed on gems, you're an obsidian dragon, so you eat obsidian - is there an obsidian vein here?"

Lin An was wrong.

However, her speculation and the facts, although somewhat deviant, are not entirely wrong.

What she found in the dragon's lair was not a giant vein of obsidian, but a hill of mana crystals.

Located on the highest peak in the middle of the island, the Demon Source resembles a volcanic crater, and the elemental torrent rolls out of the mountain mouth like a pillar of smoke.

The dragon digs a hole in the side wall directly outside the mountain pass, using the hollow cave as its dragon nest.

Not counting the length of the tail, the dragon was eight hundred yards long, squatting on the ground as tall as a four-story building, and the size of the dragon's nest must be able to accommodate such a behemoth rolling and tossing in it, you can imagine how big it is.

But this cave, which has a cross-section the size of seven or eight football fields, resembles a crystal palace, covered with fist-sized and colorful magic crystals.

As soon as Lin An came in, he was almost blinded by the light emitted by the magic crystal.

The closer you get to the center of the dragon's lair, the more amazing the size and purity of the mana crystals become.

Eventually, countless mana crystals the length of an arm, with two palms in cross-section, were nearly three feet above the ground, piled up into a hill with a flat concave top—the dragon's bed.

In the middle of the "dragon bed", a giant magic crystal with a thickness of one person holding it is erected in the middle, which is extremely dazzling.

Lin An was dazzled by the light of the giant magic crystal for more than ten seconds.

If someone attacks from the side at this time, I'm afraid she won't be able to reflect it in time.

Mana crystals are a type of energy crystal, and usually when the elemental pool of the Mage Tower is overflowing, a small amount of mana crystals will form at the bottom of the pool.

This kind of magic crystals have a strong affinity, which can quickly replenish magic power for mages, and is a precious magic material, often used as a superconducting medium, added to alchemy items and equipment, increasing the pro-magic nature of the finished product, and the effect is far beyond the mineral magic crystal and the magic crystal in the body of the magic beast, and it is a necessary raw material for making advanced equipment and powerful alchemy items.

Because of this characteristic, mana crystals can be regarded as equivalent exchanges, circulating among master-level powerhouses.

They are not produced in small quantities, but they are in greater demand, and unless the Archmage meets his needs, the excess mana crystals will be circulated on the market.

In Lin An's memory, the market price of magic crystals has always been relatively stable, because the royal families of various countries and the great nobles with rich heritage will acquire this strategic resource for a long time, and the market price of magic crystals has fluctuated significantly, which is usually regarded as a harbinger of war.

Lin An didn't build a mage tower, and although she was a tyrant, she didn't have many magic crystals at hand, and she wasn't rich enough to use it as currency.

Although there have always been sufficient materials to practice, for various reasons, Lin An's alchemy level has been lowered for a long time, and he has rarely used this kind of necessary material for making powerful potions before.

But no matter how little it is used, Lin An has also seen the true face of the magic crystal:

The mana crystals produced in the elemental pool of the Mage Tower are all two inches long and the thickness of a finger, and they are exactly the same - without a uniform standard, the mana crystals cannot be used as equivalent barter.

But in this dragon's nest, as far as Lin An could see, the smallest magic crystal was two fingers thick and one palm length.

There are no less than a million crystals in the entire dragon's lair.

Any mage would be dumbfounded when they saw this, and then they would fall into an incomparable sense of happiness!

By the time Lin An came back to his senses, Lord Nirac had been roaring for a long time.

“…… So you grew up eating magic crystals, Lord Nerac. ”

Lin An teased the new dragon servant to divert his attention and avoid his heart beating too fast and bursting his blood vessels and dying.

She surveyed the entire dragon's nest.

Probably because of being trapped in the underground space and doing nothing, the dragon also decorated the dragon's lair with great interest - it was as boring as it was to tidy up the monsters on the island and rank them according to seniority, and there was no other explanation than to pass the time idle - except for the ground, the walls and top of the dragon's lair were also embedded with various crystal clusters, which were obviously plucked from the place where the magic crystals were produced and decorated into the lair.

The light emitted by the magic crystal made the entire dragon's nest feel like a dream, as if it had entered a paradise made of crystals.

However, apart from the magic crystal, which was still a magic crystal, there was not a single obsidian.

【“…… Damn it! Despicable Terran! - If you dare to touch one of the crystals inside, I will die with you!! ”】

The roar of the dragon full of anger echoed in Lin An's mind.

Because of his lack of cooperation, the dragon was forced by Lin An to stay in place and not move.

And the master-servant contract can only allow the dragon to communicate with her when Lin An allows it - of course Lin An does not have this restriction.

Lin An's mind was dizzy for a while, and he snorted coldly, unilaterally interrupting the communication, allowing the arrogant dragon to calm down his brain and figure out its current situation.

"Yes, in the absence of obsidian veins, mana crystals are also a good substitute for gem dragons."

Of course, the Obsidian Dragon is definitely better off eating Obsidian, but some energy-curing minerals or crystals, such as Magic Crystals and Magic Crystals in the Monster's body, are also in the Gem Dragon's recipe.

Relatively speaking, things like flesh and blood are dispensable snacks for the gem dragon.

The Gem Dragons are neutral dragons, and have a lot to do with their recipes.

"No wonder it's more than 2,000 years old, and it's still stunted."

Lin An somewhat understood.

It's no wonder that His Excellency Nirac jumped to his feet.

For it, the magic crystal is not only wealth, but also the only food, and if Lin An sees the wealth, His Excellency Nirac will tragically become the first dragon to starve to death due to lack of food.

This will make the Dragons a joke for all races in the entire Crystal Wall system!

But Lin An did not intend to forgive His Excellency Nirac because of this.

Between her and the dragon, they should readjust to each other's identities, and if Lord Nerac can't adapt, Lin An might as well help him.

After cruising around the dragon's nest, Lin An found a small tunnel on the back of the "dragon bed".

Saying that it is small, it is relative to the size of the dragon, but in fact, for Lin An, three people in parallel are more than enough.

This tunnel leads to the center of the mountain, and the further you go, the higher the concentration of elements.

Lin An guessed that the dragon had opened the side wall of the mountain pass.

The high concentration of elements kept pouring into the dragon's nest, and it turned out that the concentration of elements in the dragon's nest was not entirely due to the magic crystal.

Such an environment is the one that is suitable for the magic crystal, and the magic crystal is immersed in it, and the elements gathered inside are not easy to lose.

This is equivalent to the fact that fresh meat needs to be kept fresh in the refrigerator, and mages usually keep the mana crystals in the zài elemental pool.

"Only an obsidian dragon can move freely in such an environment."

Lin An muttered to himself.

If you change to a gem dragon, you may not be able to be as close as a fish in water so close to the Demon Source.

The Obsidian Dragon's scale armor is the finest type of obsidian, which is condensed from the body after the obsidian dragon eats the obsidian mine.

Lin An speculated that there should have been obsidian here, which may have been left by the original owner of Sky City.

Because, without enough obsidian, dragon eggs simply cannot remain alive for a long time, let alone hatch.

From juvenile to adulthood, obsidian dragons go through four stages: juvenile, juvenile, juvenile, and adult, each of which requires a large amount of obsidian ore to be consumed.

Obsidian itself has a strong physical and magical resistance, and it is extremely stable, and it is often the main material of the alchemy platform and the real yàn platform that mages love - but unfortunately ordinary mages can't afford it.

Obsidian is also a precious gemstone, and only a mage who has been enshrined by the royal family and national resources can have the luxury of owning an obsidian real platform.

Lin An's portable alchemy platform and the real yàn platform in the underground laboratory of the Earl's Court are made of obsidian.

However, the quality of the obsidian used to make the obsidian platform is often not very good, but it is only a slightly better semi-refined product than the obsidian mine, and the really high-quality obsidian is usually not used by a mage to make the real obsidian.

Not to mention the dragon scales condensed from the obsidian dragon.
