The black dragon swallowed three gold bars, two handfuls of silver ornaments, and a pinch of Essence Gold Mithril, which was truly full, and the Colonization Suit was replenished like never before, ready to go, and conveyed a strong sense of feedback.

- It's really a big head.

Caesar pondered too much, I am afraid that in the future, I am afraid that he will have to swallow gold for a living, and the higher the conversion efficiency of those metals, the higher the value in Eladia, so if the nest of black wings cannot generate income in the future, he may not even be able to support himself.

Fortunately, it's him, if he changes to other real dragons and finds that the strong breeding armor is such a supplement, I'm afraid that he will cry directly, and finally either give up this ability, or simply choose to die.

However, in any case, Caesar, who found the transformation supplement, was still in a very happy mood, so the black dragon hummed an ugly tune, glanced at the old green dragon that was frozen in the compartment, and still applied another layer of ice breath, and then left with a wagging tail, exiting the treasure house and closing the door.

Although this magical door mixed with Mithril metal has been completely reduced to an ornament, as long as the black dragon is still there, no creature will dare to set foot in this place.

Beware of those adventurers though.

Yes, watch out for thieves, thieves, robbers!

This guy didn't know what he had made up, his expression suddenly became hideous, he bared his teeth, and nodded again and again with his cheeks puffed.

Now these treasures are not only treasures, but also his spiritual food, the source of energy, the root of Caesar's life, and those who dare to covet it will all be skinned and hanged.

The forest fairy looked at the black dragon's inexplicable change of expression and was confused, but fortunately, she knew that Caesar would occasionally appear in this kind of unbalanced situation, and it could be seen that the black dragon was in a pretty good mood now.

Let's play the cards.

Thinking excitedly, Luna ran into her small house, took out the iron box that she regarded as a treasure, and begged Caesar to play two games with her.

Caesar agreed, and in the Emerald Palace, the two of them sat down on the ground without any scruples (in fact, Luna was floating, while Caesar was lying down), and the forest elf faced the Black Dragon Lord.

Now he is facing the problem of how to make money, so when Caesar plays cards, he subconsciously thinks that it is possible to make a whole set of cards and then export them to collect money?

The answer is yes.

In Eladia, the card is aimed at not just teenagers, or even humans, but also immortals who have long lifespans but often lead mundane lives, such as dragons, elves, elves, and so on.

In Eladia, where there is plenty of time and entertainment is extremely scarce, such cards are estimated to explode as soon as they appear, and those who have a certain status and are not lacking in wealth are estimated to be addicted and have fun (see Luna for details).

As long as you invest the cost and effort in the early stage, embed the quality energy crystal in the card, and then use magic to record the image and sound effects into it, the gods are on top......

To be honest, even Caesar didn't know what kind of effect he could have in the end and how much money he would make after achieving this level.

This will not only solve his "eating" problem, but may also bring him a huge wealth trophy, and if the "Blackwing's Nest" mark is marked on the back of the card, I am afraid that the reputation reward will follow.

"You fucking you! What a genius. ”

The more the black dragon thought about it, the more energetic it became, looking at Luna, who was concentrating on studying how to play cards, he couldn't help but stick out his tongue and lick the little guy - RUA.

"Oops."

Luna exclaimed, the cards grabbed with mana were unstable, and finally stabilized the weak mana, and said angrily: "You must have done it on purpose, I have already calculated how to play the cards, this will definitely make you lose." Outcome...... I don't remember it now......"

She frowned her little eyebrows, grimaced, and began to study again, not paying much attention to the licking of the black dragon, as long as she encountered danger, Caesar would take her into her mouth at every turn, Luna was used to it.

Of course, the vision is wonderful, but in order to make it a reality, Caesar still needs to face many practical problems.

The cost is easy to solve, and the black dragon who got the green capital and Kaki, how can he be regarded as a small rich man, not even a few sets of cards with quality crystals can't afford to build, and Caesar still has the insight of the pattern beyond the times, if he really starts to produce, he can also create a batch of assembly line workshops, and don't worry about manufacturing costs and efficiency.

The crux of the matter is copyright.

You know, card games are not a difficult product, unlike those precious magic items, each of which needs to be carefully crafted, forged extremely difficult, and cannot be copied, and like these cards in Luna's hand, after knowing the specific gameplay and game rules, Eladia has countless creatures that have the ability to produce it.

As long as a random person comes, takes two pieces of thick paper, and hires a few painters, they can produce decent and inferior cottages, and those powerful lords can make high-end products that are better than Caesar's.

Eladia is underdeveloped, but the creatures here are not stupid.

The idea is a good idea, but after it is made, how to keep the product is what Caesar should find a way to solve, otherwise I am afraid that before the money is made, the competing products will already be spread all over the continent first.

In addition, if it is not so taken for granted, and put it into the details, Caesar still has to solve the first step of the sales problem.

Under normal circumstances, you have an inexplicable card with the name of the Nest of Black Wings, and the logo comes from a five-colored evil dragon, and other intelligent races probably won't even want to touch it, and subconsciously sweep it into the garbage heap as an evil dragon's bewitchment.

How to reverse the cognitive bias is also a big problem, and Eladia has no precedent for Caesar to follow.

Troubles sprung up one after another, and he suddenly felt that his brain was a little insufficient.

"Your Majesty."

Just as Caesar was playing cards with Luna while wandering outside the object, he suddenly heard a respectful whisper from outside the palace, he turned his head, and found that the leader of the flying dragon, Erha, appeared outside the hall at some point, followed by a trembling shapeshifter.

"Your Majesty, they trespassed on the edge of the palace without permission, and I wanted to kill them, but these guys said they came on orders and fulfilled your orders."

Erha looked up at him, and after getting the black dragon's permission, he took a few steps to the right with his wing joints and hind legs, allowing the shapeshifter to enter.

"Your Majesty, as soon as you left, we started collecting at Kaki Ling and brought what you wanted."

The shapeshifters dragged a few large boxes and knelt in front of the black dragon, their leader didn't come this time, and he was probably worried, and the human thing was enough for that guy to slowly understand and absorb.

When the box was opened, it was not expensive gold and silver treasures or magical curiosities, but some ordinary books, and Luna floated over curiously to look at them:

The God We Believe In

Elemental Power – From Beginner to Master

A Brief History of the Continent

"The Forge of Magical Wonders"

Adventurer's Guide: Bismarck's Survival Wisdom

Bestiary

Schiller's Selected Poems

The Immortal Sun Never Sets

"The Self-cultivation of the Lord"

……

The little one's expression was confused at first, then surprised, and finally suspicious, and only after the shapeshifter bowed and walked away did she ask, "Isn't it?" Caesar, what do you want these human books for, could it be that you have a collector's habit? ”

"No!"

Heilong said righteously: "I love to learn, and learning makes me happy." ”

He had been longing for these things for too long, because of his lack of common sense, this guy had suffered countless losses in Eladya, and he couldn't stand the life of illiteracy anymore!

Moreover, the establishment of a complete knowledge and cognitive system helps him to think about problems that cannot be solved at present, and maybe he can think of solutions from them.

This is one of the reasons why Caesar is trying to dominate Kaki, without the power of the upper nobles on the human side, he really doesn't know how to get his hands on such a large number of precious books.

Even if the black dragon is willing to bleed the capital, he wants to contact humans through shapeshifters, and then rely on the magic and strange things to trade in exchange...... It's also very difficult, ordinary businessmen simply can't get such a complete book.
