More than 500 years ago, Rosenberg, the founder of the card theory, first proposed the card theory and successfully made the first card. Since then, after more than 500 years of development, various cards have emerged one after another. Before that, the prototypes of original cards existed in various religions in large numbers, and they were considered to be an unnatural force. Until now, some religions still have many card makers and cardmakers with extremely skilled skills. Their source even exceeded the Rosenberg era. In this regard, their inheritance is even more mysterious and unknown.

But it was Rosenberg's emergence that completely shattered the mysterious halo on the card system. He systematically studied and explained the card structure and invented many cards. For example, today's energy cards, its standard structure was first proposed by Rosenberg. The mysterious halo on the card was completely broken, and card science became a new discipline.

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

The era where Henner Vancent was located was an era of many heroes. During that hundred years, countless cards were invented by many genius card makers. As a great card makers as famous as Rosenberg, Henner Vancent invented as ninety-seven cards. During that period, many famous card makers in later generations emerged, such as Rozzi, Chemoshe, etc.

After so many years of development, card science has long been very different from five hundred years ago. The entire discipline has become more detailed, with many branches, and more in-depth research.

The card theory of the Tianyou Federation was introduced into the two domains as the Mohadi Domain and Baiyuan Prefecture established diplomatic relations normally. The outstanding people in the two domains quickly absorbed them and developed a unique card theory suitable for their two domains based on the characteristics of their domains. Therefore, the card theory system was further supplemented and expanded, and new cards emerged one after another. It was a brilliant era, an era that countless people yearned for.

With the continuous development of the card theory system and the emergence of various strange cards, it is becoming increasingly difficult to divide the types of cards. So far, there is no authoritative division method.

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

You need to use a meter when using a card. Coincidentally, the meter was invented by Rosenberg, the founder of the card theory, and was perfected by Hainer Vancent. Although the meter is becoming more and more exquisite, and there are more and more auxiliary functions. For example, Chen Mu's meter has a searchlight on it, its core still has not changed at all.

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

Of course, Chen Mu's meter is not a high-end product. What high-end product can Odi buy for more than 200 years? Chen Mu is rarely used in this item that uses a very wide range of meters.

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

"drop!"

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

"The energy card does not meet the specifications, please use Samsung or above energy card!"

Samsung Energy Card! You actually need energy cards above three stars! Chen Mu, who was surprised, has confirmed that this card is an absolute high-end card. Generally speaking, the higher the card, the higher the level requirements for the energy card and the faster the energy consumption speed. Chen Mu still has this common sense.

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

The energy capacity of a one-star energy card is one hundred cards, the two-star energy card is one thousand cards, and the capacity of a three-star energy card is as high as ten thousand cards.

The unified retail price of a one-star energy card is 110 Odi, that is, the average energy of one card is 1,250 Odi. On average, the energy of one card is 1,250 Odi. On average, the energy of one card is 1,250 Odi. On average, the energy of one card is 1,250 Odi. On average, the price of a three-star energy card is as high as 15,000 Odi. On average, the energy of one card is 1,500 Odi.

This is why one-star energy card has the widest range of use. After all, there are still the most poor people in this world.

Over the past three years, he has been saving money and working day and night, and his entire net worth is only 80,000 Odi. He has to pay out 15,000 Odi at once, which makes him very hesitant. After experiencing a wandering life since childhood, he values ​​money more than ordinary people because he knows that this is the most basic of life.

After hesitating for a long time, reason finally defeated the impulse. Chen Mu decided to leave it for a while before talking about it. He did not throw away the two films posted on the card, but kept them.

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

But life has to continue, and he has accomplished nothing during this period. He has successfully set up the paper-compression structure in another one-star energy card with different structures into his own structure, which has once again reduced the cost of making one-star energy card by two Odi. In other words, his daily income is fifty Odi more than before.

It can be said that the structure and standard structure of the one-star energy card he made now are already quite different, but if you don’t look carefully, it will be difficult to see. However, who would carefully study the one-star energy card he just bought?

He took out the lecture certificate given to him last time. According to the date, it was today.

The training class was held in a building next to Dongwei Academy. Originally, Chen Mu thought that there would not be many people coming to participate, but unexpectedly, when he walked into the classroom, he found that there was noisy inside. There were all boys and girls sitting inside. The young people were naturally beaten up quickly, laughing and scolding, and there were piles of people in three or five, and they had a lot of fun.

Chen Mu casually found a seat by the window and sat down. After years of wandering life, Chen Mu had a lot of experience in observing her beauty. After a quick glance, he realized that the family background of these people was probably ordinary. Think about it, if the family had money, how could he send his children to such a low-level training class? He would also send them to Dongwei Academy.

Looking at the Dongwei Academy, which is only separated by a wall outside the window, from this location, the playground of the Dongwei Academy is fully visible. The neat and clean uniforms are filled with a confident smile, and the polite greetings to each other, the students of the Dongwei Academy are eye-catching.

Inexplicably, Chen Mu felt a little uncomfortable, and a little bitterness suddenly rose in his heart. Withdrew his gaze, Chen Mu sat there for a while, and came to his senses and couldn't help laughing.

What's wrong with me? Three years ago, I was afraid I would never have dreamed of living such a life. Now, what else can I feel dissatisfied? I secretly warned myself that I must be content, and I am already very lucky!

Chen Mu, who figured this out, turned his attention to Dongwei Academy again, with a faint envy in his eyes, but it was extremely peaceful.

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

The teacher who taught was a young man in his twenties, named Jia Ming. He looked average but had a very neat mouth. He said a lot from the beginning, saying that he was a direct disciple of Professor Jia Ziling from Dongwei Academy and was a partnership with Dongwei Academy. After everyone got to learn, it would be a very simple thing to find a job. Without bragging and admonition, the students below were just shining with their eyes.

Chen Mu frowned when he heard this. His life since childhood has given him insight into the world, which is far from comparable to these young girls and boys. In his opinion, this lecturer is far more like a liar than a cardmaker.

This boast took a full half morning.

Half a morning disappointed Chen Mu. Jia Ming was completely reading the script. For three years, Chen Mu had been studying by himself, and he had read no less than a hundred basic books, many of which were meticulous. He even knew that Jia Ming was now a common theme in various schools. The "Introduction to the Basics of Card Theory" compiled by Wang Jing, the zero-fourth edition.

He has read this book less than ten times, but because his foundation is too poor, many parts are still unclear.

Soon he concentrated on listening.
