More than five hundred years ago, Rosenberg, the founder of card theory, first proposed card theory and successfully produced the first card. Since then, after more than 500 years of development, all kinds of cards have emerged in endlessly. Before this, primitive card prototypes existed in large numbers in various religions, and they were considered to be an unnatural force. Until now, some religions still have many extremely skilled card makers and card repairers. Their origins even exceed the Rosenberg era. In this regard, their inheritance is even more mysterious and unknown.

But it was the emergence of Rosenberg that completely shattered the mysterious aura of the card system. He systematically studied and elaborated on the card structure, and invented many cards, such as today's energy card, whose standard structure was first proposed by Rosenberg. The mysterious halo surrounding the cards was completely broken, and card science became a new discipline.

About three hundred years ago, another great card maker, Heiner Vincent, brought the development of cards into the golden age. The year when Heiner Vansant was born happened to be two hundred years after the year when Rosenberg formally proposed the card theory. These two greatest card makers in the past five hundred years seemed to be echoing in this way.

The era in which Heiner Vincent lived was an era in which heroes emerged in large numbers. During that one hundred years, countless cards were invented by many talented card makers. As a great card maker as famous as Rosenberg, Heiner Vansant led the invention of as many as ninety-seven types of cards. During that period, many famous card makers emerged, such as Rozzi, Chemosikh and so on.

After so many years of development, card learning today is completely different from what it was five hundred years ago. The entire subject has become more detailed, with many branches, and research has become more in-depth.

The Tianyou Federation's card theory was introduced to the two realms as the Mahadi Realm and Baiyuan Mansion established normal diplomatic relations. The outstanding people from the two realms quickly absorbed it and developed unique cards suitable for their two realms based on the characteristics of their own regions. theory. As a result, the card theory system was further supplemented and expanded, and new cards emerged one after another. It was a glorious and splendid era, an era that countless people deeply yearned for.

With the continuous development of the card theory system and the emergence of various strange and weird cards, it has become increasingly difficult to classify card types. Until now, there is no authoritative classification method.

However, if you want to know what a card does, there is one most direct and easiest way, and that is to use it!

To use cards, you need to use a meter. Coincidentally, the meter was also invented by Rosenberg, the founder of card theory, and perfected by Heiner Vansant. Although today's measuring instruments are becoming more and more sophisticated and have more and more auxiliary functions. For example, Chen Mu's measuring instrument has a searchlight, but its core has not changed at all.

From the outside, the meter looks like a rectangular box with three buckles that can be buckled on the arm. There is a card slot on the top of the meter, which is used to use cards. Generally speaking, a meter has at least two card slots, and the more advanced the meter, the more card slots it will have. One of the two card slots is for basic cards such as energy cards, and the other card slot is for inserting the cards the user wants to use. To put it bluntly, the meter is a device that connects the energy card with other cards. The energy card provides energy to stimulate the card to achieve the purpose of use.

Of course Chen Mu's instrument is not a high-end product. What kind of high-end product can be bought with more than two hundred euros? Chen Mu rarely used the instrument, an extremely widely used item.

Without hesitation, he inserted this card into the slot above the meter, picked an unused one-star energy card and inserted it into the slot below. After doing all this, Chen Mu took a deep breath, and then pressed the activation button on the dial.

"drop!"

Chen Mu suddenly appeared a translucent light screen with a line of words on it.

"The energy card does not meet the specifications, please use an energy card of three stars or above!"

Samsung energy card! He actually wants an energy card worth three stars or above! Chen Mu, who was full of surprise, had already determined that this card was an out-and-out high-end card. Generally speaking, the more advanced the card, the higher the level requirements for energy cards, and the faster the energy consumption. Chen Mu still has this bit of common sense.

But Chen Mu was in trouble again. He didn't have a Samsung Energy Card. If he wanted to know what kind of card this card was, he had to buy a Samsung Energy Card. However, the price of Samsung Energy Card is not a small amount!

The energy capacity of a one-star energy card is one hundred calories, that of a two-star energy card is one thousand calories, and that of a three-star energy card is up to 10,000 calories.

The unified retail price of a one-star energy card is one hundred and ten euros, which means that on average, one energy card costs one euro. The price of a two-star energy card is 1,250 euros. On average, one card of energy costs 1.25 euros. The price of Samsung Energy Card is as high as 15,000 Oudi. On average, one energy card costs 1.5 Oudi.

This is why the one-star energy card is the most widely used. After all, there are still the most poor people in this world.

In the past three years, he has lived frugally and worked day and night, and his total net worth is only 80,000 euros. He was very hesitant to take out 15,000 Oudi at once. Having experienced a wandering life since he was a child, he values ​​money more than the average person because he knows that it is the most basic foundation of life.

After hesitating for a long time, reason finally defeated impulse, and Chen Mu decided to put it aside for a while. He didn't throw away the two films affixed to the card, but kept them.

The days have returned to calm, but Chen Mu has made another habit. Every day he can't help but put this card in his hand and play with it. Every time he looks at this card, he will be immersed in the complex and perfect texture.

But life has to go on, and he has not accomplished anything during this period. He successfully set the loop compression structure in another one-star energy card with a different structure into his own structure, which allowed him to make a The cost of the Star Energy Card has once again dropped by two odi. In other words, he now earns fifty Oudi more per day than before.

It can be said that the structure of the one-star energy card he is currently making is quite different from the standard structure, but it is difficult to see it if you don't look carefully. However, who would carefully study the one-star energy card they just bought?

He took out the lecture card that Uncle Hua gave him last time. According to the date, it was today.

The training class was held in a building next to Dongwei Academy. Chen Mu originally thought that there would not be many people attending, but when he walked into the classroom, he found it was noisy. There were all young boys and girls sitting inside, and the young people naturally got into a group very quickly, laughing and scolding each other, in groups of three and five, having a great time.

Chen Mu casually found a seat by the window and sat down. Years of wandering have given Chen Mu a lot of experience in observing faces. After a quick glance, he realized that the family background of these people was probably ordinary. Think about it, if your family is rich, why would you send your children to such a low-level training class? If you want to send it, send it to Dongwei Academy.

Looking out the window at Dongwei Academy, which is only separated by a wall. From this position, the playground of Dongwei Academy can be seen at a glance. With neat and clean uniforms, confident smiles, and polite greetings to each other, the students of Dongwei Academy are eye-catching.

Inexplicably, Chen Mu felt a little uncomfortable, and a hint of bitterness quietly rose in his heart. Withdrawing his gaze, Chen Mu sat blankly for a long time. When he came back to his senses, he couldn't help but laugh.

What's wrong with you? Three years ago, I never dreamed that I would be able to live such a life. Now, what else am I dissatisfied with? I secretly warned myself that I must be content, as I was already very lucky!

After thinking about this, Chen Mu turned his attention to Dongwei Academy again, his eyes still had a touch of envy, but they were unusually peaceful.

At this moment, the teacher walked into the classroom, and the classroom immediately became quiet.

The teacher giving the lecture is a young man in his twenties named Jia Ming. He looks average but has a very sharp tongue. He talked a lot at the beginning, saying that he was a direct disciple of Professor Jia Ziling from Dongwei University, and that he and Dongwei University were partners. After everyone completed their studies, it would be a very simple matter to find a job. Without bragging or encouraging, the students below were so excited that their eyes lit up.

Chen Mu frowned when he heard this. His wandering life since he was a child gave him an insight into the world that was far beyond what these girls and boys could compare with. In his opinion, this lecturer looked more like a liar than a card maker.

This bragging took half the morning.

For half the morning, Chen Mu was disappointed. This Jia Ming was completely following the script. In the past three years, Chen Mu has been studying on his own. He has read no less than a hundred basic books, many of which he is familiar with. He even knew that what Jia Ming was currently reading was the 2004 edition of "Introduction to the Basics of Card Theory" compiled by Wang Jing, which was commonly used in various schools.

He has read this book no less than ten times, but due to his poor foundation, many parts are still unclear.

Soon he was concentrating on the lecture.
