Leno and Dinas followed Nelly around the east side of the archipelago until noon.

Nelly arranged lunch for Li Nuo and the others at the exchange. After the meal, Li Nuo and Nelly learned a few things, and finally left the exchange on the grounds that they "still have to think about it".

This morning, there are more than 300 islands with a price of less than 100,000 gold coins.

With the exception of the No. 1 Snow Mountain Island, which has been hollowed out of its mineral resources, the rest of the islands are small islands with a width of no more than 10 kilometers.

These small islands are difficult to develop and utilize due to their small size, remote location, or the large number of underwater reefs. For example, the construction of a magical ecological farm, a large magical water purification facility, the construction of a port, etc., cannot be achieved on such small islands.

In addition, the security force on the eastern side of the archipelago is another important factor affecting the price of the island.

The Deep Sea Branch is responsible for providing security services.

Almost every thirty kilometers, there is a magic sentry. It is an unmanned magical device suspended above the sea, patrolling the sea between the islands.

Magical Servants are staff members within the Outpost.

Wherever there is a fight, the magic sentry will rush over as soon as possible, and use brilliant fireworks to notify the wizard strongholds set up by the Deep Sea Branch between the islands.

When the deep sea wizards in the wizarding stronghold receive the news, they will immediately rush to the scene to deal with the dispute.

The closer you get to the patrol route of the magic outpost, and the closer you are to the stronghold of the Wizard of the Depths, the higher the quality of the security service, and the higher the price of the island.

After taking into account the location of the islands, the quality of public security, the topography, the number and size of safe havens, the price, and other factors, there are 15 islands that fully meet the requirements of Li Nuo and the others.

Among them is the No. 1 Snow Mountain Island.

The islands of Snow Mountain No. 1 to No. 3 are close to each other.

Before they were exploited, the three snow-capped islands were extremely rich in resources.

In order to prevent theft, the Deep Sea Branch has set up wizard strongholds and magic outposts near the three snow-capped islands.

The wizarding strongholds and magic outposts of the Deep Sea Branch will not be easily changed once they are established. Therefore, even if the mineral resources on the No. 1 Snow Mountain Island are emptied, it is still within the scope of high-quality security services.

After Li Nuo screened out the 15 islands that met the requirements, he did not rush to pay the money.

As he told Nelly, "he needs to think again."

However, he did not consider picking one of the 15 islands.

What he really thinks about is "stealing chickens".

He discovers a system knowledge that he has overlooked, but is extremely important.

As we all know, if you have mastered the decomposition and knowledge skills related to something before deconstructing it, then the deconstruction cost will be reduced.

The formulation of the system usually looks like this:

Based on the results of your deconstruction of XXXX, the cost of this deconstruction has been reduced.

Or something like this:

Due to your mastery of "XXXX Studies (Level XX)", the cost of this deconstruction has been reduced.

The appearance of these two systematic texts means that what Li Nuo is trying to deconstruct is related to the decomposition results and intellectual skills he has mastered.

So the question is, can this very common system knowledge be used to explore island resources?

For example:

Before he mastered a skill such as "Mineral Exploration", Li Nuo threw a deconstruction technique at Island A and obtained the unreduced deconstruction consumption A1.

Then, through self-study, he mastered the knowledge and skills, and threw the deconstruction technique towards Island A again to obtain the deconstructed consumption data A2 after the reduction.

The difference between A1 and A2 is the amount of deconstruction consumption reduction that you can enjoy after mastering "Mineral Prospecting".

On the premise that the reduction value is only related to academic skills, it is not difficult to deduce a conclusion:

The greater the amount of resources related to learning skills on the island, the greater the reduction in deconstruction consumption.

By comparing the reduction values of each island, you can deduce the amount of resources on the island!

By comparing the reduction of deconstructed consumption on different islands with the resource reserves on the island data, we can further obtain rough data on how many resources have not been discovered by human exploration.

This is the system knowledge that is often overlooked, but extremely important.

As long as you learn and put it into practice, the effect is extremely amazing.

Thinking of this series of operations, Li Nuo has to thank the math content he learned in high school and college. Because many of the ideas in these calculation operations draw on mathematical knowledge points such as "algebra", "derivative", and "limit".

As soon as he left the Island Exchange, Li Nuo took Dinas to the Free Bazaar in the trading area.

The Freedom Market is a commercial plaza covering an area of more than 50,000 square meters.

Its centerpiece is the Magical Items Trading Center. Numerous shops are located around the white-walled trading center, filling the entire commercial plaza.

After entering the bazaar, Leno and Dinas split up.

Living on an island, there are many essential necessities to buy. Dinas took care of the groceries shopping. She would stay in the department store at the Liberty Market until Li Nuo came to look for her.

Li Nuo shuttles through the crowded streets alone, looking for everything related to academic skills.

His goal is clear.

First, he had to find a scholarly book on natural resources.

Regardless of whether it is a book on exploring resources or excavating resources, Li Nuo will not refuse to come. As long as you can unlock academic skills, it's a good book.

Second, he's on a quest to find texts related to the Demon Stealer Society and the ancient dragons.

The purpose of collecting books related to the Demon Stealer's Society is to find inspiration for the use of "Mana Steal".

"The Wizard's Path" and "The Roots of Magic" only briefly mention the extraordinary things about the Demon Stealer Society, but do not elaborate on what they did.

Today, the Demon Stealer Society is a thing of the past, a millennium ago, to say the least.

This wizard's power is not as famous as the dragons, and its influence is not as great as that of the dragons, so it should be a troublesome matter to find its historical materials.

In contrast, antiquities related to dragons are not uncommon at free fairs.

As a legendary race, people are very curious and eager to explore dragons.

This has led to a situation in which the number of fakes is high.

After walking down a street, Leno saw no less than a hundred fakes made of modern magic techniques, and these fakes were all related to the dragons.

The number of fakes far exceeds the number of genuine products, and the real thing has become a one-of-a-kind existence.

There are so many races that have disappeared into history, so why should the counterfeit makers keep an eye on the dragons?

The answer has to do with the Spin Continent, 1,000 kilometres south of the Suman Islands.

The Flying Spin Continent is the only place in this world where dragons haunt it. The Suman Islands are also the only human territory adjacent to the Spin Continent.

More than half of the extraordinary people who come and go here in the Suman Islands go for the singularities of the Spinner Continent.

Spinning, as the name suggests, is a continent that flies in the air and spins non-stop. Under the action of centrifugal force, the Flying Continent will throw the treasures of the dragon clan out of the continent from time to time. These treasures will drag a long tail flame and fall into the vast sea beyond the Vortex Continent.

Most of the dragon's treasures have sunk to the bottom of the sea, and only a few of them can be caught by ships crouching on the surface of the sea and then traded in the Free Bazaar.

The Magic Goods Exchange in the center of the Free Bazaar is dedicated to trading dragon treasures.

Dragon Treasure does not refer to "Dragon Produced Treasure". As the overlord of the previous era, the dragons scavenged the precious resources of other races and stuffed them into their own treasure troves and became part of the dragons' collection.

Statistically, less than one-tenth of the dragons' treasures that were successfully captured were homemade by the dragons, and the remaining ninety percent were looted by the dragons from other races.

What Li Nuo is looking for is research materials for the dragon clan, or chronicles, geographical materials, chronicles, lists of dragon clan members, and so on compiled by the dragon clan himself.

These are the only things that can help him reduce the cost of deconstructing the island.

It would be great if you could find information directly related to the "Dragon's Tooth Reservoir".

With this information, when Li Nuo tries to deconstruct the strange island related to the Dragon's Tooth Reservoir, he will directly get the news of the deconstruction of the consumption reduction, and then determine that this island is closely related to the Dragon's Tooth Reservoir.

With a clear goal, clear thinking, and extremely convenient deconstruction, Li Nuo easily found what he was looking for.

It's a small shop cowering in the most remote corner of the bazaar, with a painted wooden sign with a succinct line of crooked handwriting:

"Headway's shop – my shop only sells genuine products."

The owner, Headway, seems to have just returned from the sea.

He had a heavy magical canvas bag on his back, and his cloak was wet, leaving a trail of damp footprints as he walked.

When Leno arrived, Headway was facing away from him, pulling out the keychain from his pocket under his cloak and pounding at the keyhole on the door.

Headway is huge, looking like a hunchbacked bear from the back.

After failing to insert the key into the keyhole twice in a row, Headway let out a dull sigh and fumbled his wide palm in the magic canvas bag behind his back, pulling out a pair of glasses with a strap and tying them to his face.

It seems that Headway has a slight vision problem. After fastening his glasses, he immediately saw the direction of the keyhole and successfully opened the front door of the store.

A musty smell that had not been ventilated and received light for a long time wafted out of the house, and Li Nuo could smell it from a distance of several meters.

Headway bent sideways and squeezed inside the door. Just as he turned to close the door, he noticed Li Nuo lingering not far from the door.

Li Nuo also saw the appearance of the shopkeeper because of this.

A large shaggy face with a brown beard and hair and two eyes covered by coin-sized lenses. The combination of a wide face and tiny lenses makes him look a little funny.

Headway faced Li Nuo, scratched his beard, and said with a slight smell of wine:

"Are you here to buy something? Hiccup~"

"That's right, I have a crush on the dragon's teeth hanging on the outside of my backpack." Li Nuo raised his hand and pointed to the outside of the backpack behind the other party.

Headway reached behind him. There were a number of things hanging from the outside of his backpack, and the dragon's teeth were inconspicuous in them.

He used his touch to distinguish what Li Nuo was referring to, and said with the smell of wine:

"Oh, you say this, it's my lucky thing, I don't sell it for any amount of money. Belch~... I have some other stuff here that you might be interested in. However, I have just returned from the sea, and I haven't sorted out the harvest of this trip yet, so I don't have time to introduce you to the store for the time being, so you can just come in and take a look at it yourself. But remember, if you don't buy it, don't touch it. ”

Headway beckoned to Li Nuo, inviting him into the store, and then began to organize the contents of his backpack on his own.

The shop is small, with a roof five meters above the ground, surrounded by a clutter of shelves and a dim chandelier on the ceiling as the only source of light.

After Li Nuo entered the store, he looked around the scene in the house and knew that he had come to the right place.

Just like what Hideaway wrote on the sign, the merchandise here is genuine, and it has indeed been collected by the dragons, or it has come from the dragons themselves.

Most of the goods are small objects of unknown purpose made of metal or stone, and a small part are strange things such as dragon teeth, dragon scales, dragon dandruff, etc.

Li Nuo used deconstruction to determine the authenticity of these things, but their quality was really not flattering, and they were all tattered.

Not to mention the severe defects, there are also obvious traces of weathering and sea erosion, which greatly reduces the quality of the goods.

Li Nuo noticed that the deconstruction consumption of things that originated from the dragon itself was relatively large, and it had nothing to do with the size.

The most typical is the thumb-sized dragon teeth, yellow and clear, full of dents and gaps, and the light shines on the surface with the feeling of applying oil and wax.

Just this little thing, Li Nuo needs more than 10,000 energy points to completely deconstruct it.

Li Nuo took a closer look, but he didn't see anything from the dragon's teeth.

He glanced back at Headway, who was picking up the clutter in his backpack, and asked in a half-believing tone:

"The dragon tooth you put on the shelf, is it really a dragon tooth? It looks like a sharpened phalanx..."

Headway reacted violently to Li Nuo's questioning. He slapped the sundries in his hand on the table with a snap, stood up straight at the table, and glared at Li Nuo:

"Of course it's true! Every single thing I have here is real! It's all to blame on those bastards who sell fakes! Everyone who comes to me to buy something asks me if it's real! ”

Headway appears to have been tormented by his peers who sell fakes.

Think about it, too, after the sale of fakes has formed a complete system and evaluation criteria, the public perception will be distorted by fakes.

After all, not everyone has enough knowledge to be able to distinguish the real thing from the fake.

Most of the buyers are new or ignorant of dragons. In this case, it is easier for customers to believe that the fake is genuine after the words and routines carefully packaged by the fake seller.

In the long run, the genuine products will be expelled by the fakes, resulting in a phenomenon similar to "bad money drives out good money".

For example, the dragon's tooth that Leno is referring to.

Some of the fakes will be made crystal clear and flawless. This part of the fakes was sold to unpopular buyers who had no knowledge of the dragons.

If the buyer knows little about the dragons, then the deliberately distressed fake dragon teeth will be put on the table by the seller.

With the blessing of magic, fakes have reached the point of being fake, but the cost of fakes and genuine products is one place and one day.

Fakes can be made in the Magic Workshop and are inexpensive to make.

Authenticity requires the owner to find the real source, or to go out to sea to catch the treasure that flew out of the Spinner Continent like Hideaway, or to go deep into the ocean floor to find the lost things that lie dormant on the seabed.

Li Nuo understood Headway's mood and the grievances in his heart very well, and he deliberately used these words to stimulate the other party.

The reason... It's very simple, and it's the same as "buying headphones". If you don't know which headphones are best under 300 yuan, don't ask "what headphones are recommended under 300 yuan", but say "there are no good headphones under 300 yuan".

Although this kind of fishing-like practice is hateful, it is concise and efficient, and it is easiest to stimulate people who have real materials and are upright to come out and speak out.

Headway is such a person.

In the face of Li Nuo's questioning, he unceremoniously complained about the fake, then took off his glasses, looked at the dragon tooth pointed by Li Nuo from a distance of a few meters, and said impatiently:

"That's the teeth of a young dragon, that's why they're so small. To be precise, the teeth that were discarded by the hatchlings when they first changed their teeth. The tooth is at least 5,000 years old, and it's normal for it to look tattered. The dragon teeth you see in other shops are basically fake..."

Headway suddenly said in frustration like a deflated balloon:

"Forget it, forget it, believe it or not... All I can say is that everything I have here is true. I hate fakes more than you do..."

Headway put on his glasses and continued to sort through the clutter on the table.

Li Nuo nodded slowly behind his back, basically figuring out Headway's personality, personality and characteristics.

This is a more upright, more reclined deep sea wizard. At a time when other shopkeepers were lazy in the bazaar by selling fakes, Headway chose to go to the sea to catch dragon treasures and sell them in his own shop.

Under normal logic, such a hands-on shopkeeper would have a lot of genuine products, and he should have had a better business, but why would he be so down.

Li Nuo has a lot to say about this.

One of the reasons must be that the fakes are too real.

The second reason is that with dragons almost extinct, modern magicians have found materials to replace dragon materials. As a result, the demand for dragon materials in the magic manufacturing industry is almost zero.

The third reason is that Li Nuo thinks it is related to the cost of identification.

Before Li Nuo found Headway's shop, he went to the appraisal shop in the bazaar to check it out.

"Erudito Association" certified appraiser, a single appraisal fee starts at 100,000 gold coins.

There is no "Erudito" certified appraiser, and the single fee starts at 10,000 gold coins.

Regardless of the type of appraisal service provided by the appraiser, the price charged exceeds that of most fakes. In addition, when the fake is sold, it comes with an appraisal report, so naturally few buyers pay money to ask others to appraise it.

Under the cross-action of various factors, the things that Li Nuo saw in the Hideaway store, whether new or old, complete or not, were all exactly the same in other stores, just like the owners of other stores had copied them here.

In the face of such a level of authenticity, if the real Hedaway product is sold a little more, it will have no competitive advantage at all.

"How much does this dragon tooth cost?" Li Nuo asked.

Headway turned his head and glanced at Li Nuo:

"330 gold coins, no bargaining. Do you want it? If you want it, I'll wrap it for you. ”

"Well, it's quite expensive, I'll take a look. When was the last time you sold something? Li Nuo asked again.

Headway scratched the mustache on his chin:

"Uh... I think it was a month ago, I can't remember exactly. ”

In the case that fakes can be faked and real, the real thing is still sold so expensive, and there will be ghosts if things can be sold...

Li Nuo squinted and looked around, thoughtful in his heart.

He seems to have found a good way to gain a lot of energy and master academic skills.

Sure enough, as soon as he left the corner of Dianjin Island, there were more magical things around him, and even the small objects that could be used for passive deconstruction became more and more abundant, and his arrangement to leave Dianjin Island was indeed right.

The only bad thing is that you have to spend gold coins everywhere you go.
