Chen Mu's heart moved, and his fingers flexibly pulled out a one-star energy card from it, put it in front of him and looked at it carefully.

Judging from the surface structure, this one-star energy card is nothing surprising. It uses the most widely used Bax structure and the most common structure. However, Chen Mu still noticed a trace of strangeness in this card.

Weight - This card is a little heavier than the average one-star energy. After making tens of thousands of one-star energy cards, Chen Mu has long been familiar with the weight of the one-star energy card. No matter what structure it uses, as long as it is a one-star energy card, its card weight will not exceed a specific range.

Obviously, the weight of this card is not within this range.

Close his eyes, gently rubbed the one-star energy card's clamp surface with his index finger and thumb. Chen Mu carefully felt the slightly raised structure on its surface.

The structure is too shallow and weak, this feeling...this feeling...Chen Mu frowned and recalled this feeling of familiarity.

Thinking of it... Chen Mu's eyes suddenly lit up - just like the result after painting on some lighter material!

But it was wrong, and Chen Mu couldn't help but feel even greater doubts. From the perspective of feel, the material of this one-star energy card is extremely hard and has a heavy feel. According to general rules, the textures portrayed on it should have a stronger texture.

How could I feel like this? It's so strange!

After carefully checking the energy card in his hand, Chen Mu still did not find anything that caused this strange phenomenon. There was no error in the structure, and from the smoothness and beauty of the brushstrokes, this was definitely a master-level level. Even though he had made a one-star energy card for three years, with his own skills, he could not draw such beautiful lines.

This also made Chen Mu even more confused. The master-level one-star energy card is a bit strange. Which card-making master would make a one-star measurement card? If he had a five-star energy card in his hand, Chen Mu would feel that it was more normal.

After thinking about it, Chen Mu put this strange card with the one-star measuring card with the new structure he had just discovered.

Chen Muchang finally finished his work and breathed a sigh of relief.

He has been concentrating on his work and now he feels a little tired.

"I'll take these two cards away." Chen Mu raised the two one-star energy cards in his hand.

"No problem, no problem." Xiao Hei said with a smile. He had gained a lot today. Chen Mu helped him find five unused energy cards today, and his mouth was almost smirking.

In Xiao Hei's heart, Chen Mu is quite strange. Judging from his clothes, you can tell that he is a poor child. Children like this will never let go of every bit of saving. The unused energy cards in their hands are a lot of money in their eyes! Chen Mu was strangely not concerned about these unused energy cards, but was very interested in those one-star energy cards, and they were all used up energy cards.

Of course, these things will only be thought about in his heart, and he would rather like this. If Chen Mu were normal, the energy cards in his hand would not fall into his hand. It was all money!

While intoxicating his foresight in his heart, he smiled and sent Chen Mu away.

When he got home, it was already ten o'clock in the evening. After eating something randomly, Chen Mu couldn't wait to take out the two energy cards he got today to study.

The first one-star energy card made Chen Mu's eyes lit up.

This is a structure he has never seen before. The complex structure is composed of light blue lines, covering the entire card surface. This one-star energy card playing card is the size of a piece of software, and the card surface is smooth, but if you caress it carefully, you can feel the raised structure.

When ordinary people see such complex patterns, they are afraid that they will feel dizzy and don’t know where to start.

Chen Mu's eyes shone brightly. For three years, he had to face similar patterns every day. Although the structure was different from the one in front of him, the complexity was comparable. The twelve new structures also accumulated a lot of experience for him.

If you want to consider the structure structure of a card, you must find its starting point, which is the landing point of its first stroke. Then follow the lines and veins to continue to deepen, so that it will be easier to understand.

Although the one-star energy card is complex, it is the simplest of all cards. However, even so, it was not until three hours later that Chen Mu really understood the effect of each of its transactions. However, to make the same one-star energy card, he still needs a lot of practice. But he gave up this intention, and a lot of practice means a lot of consumption. At least until now, although he has a little savings, it is not enough to make him squander so much.

Most importantly, he has calculated that the cost of this new structure of one-star energy card is slightly higher than the one he makes now. Spending a lot of money to practice a new structure that has no meaning to him is not his style. However, this energy card still has something to learn from. A paper compression structure may be integrated into his own energy card structure.

Chen Mu thought, but his fingers couldn't help but slide over another one-star energy card. His eyes fell on the second energy card he just obtained.

There is nothing surprising about the drawing of this one-star energy card. It is the most widely used standard one-star energy card drawing method now. However, what attracted Chen Mu's attention was the strokes of this card.

The lines are beautiful and smooth, the strokes are extremely skillful, and each turning arc is round and full, with a master-level handwriting.

This card looks quite old, and it looks quite old at first glance. I guess it was an early work by a master. But it was not these two points that caught Ye Chong's attention first, but its weight and thickness.

This old one-star energy card is one tenth heavier than an ordinary energy card. The weight of the one-star energy card itself is very small, and even one-tenth is difficult to detect. However, Chen Mu made too many one-star energy cards, so he felt it when he first picked up this one-star energy card. The same is true for the thickness, and the thickness of this one-star energy card is thicker than that of an ordinary one-star energy card.

This is the biggest reason why this card attracted Chen Mu's attention. One-star energy card was the earliest card that appeared and the most used card. Its specifications were formulated at the beginning of its founding. Until now, the so-called standard structure and standard materials are no different from the ones they were founded.

How can there be such a difference in a one-star energy card made by a master?

Could it be...

Chen Mu naturally thought of the material. Did this unknown master find new materials for one-star energy card? In order to make a living, Chen Mu has been committed to how to reduce the cost of one-star energy card. This one-star energy card aroused his strong interest.

After taking out the energy card from the energy meter, the room suddenly fell into darkness.

After hesitating for a moment, Chen Mu gritted his teeth and inserted the strange one-star energy card in his hand into the energy meter at home.

Hey, it's not bright! The room is still dark, without a trace of light.

Chen Mu was stunned. How could he not light up?

Impossible! This is the first thought that popped up in Chen Mu's mind. There is no trace of using this card, and Chen Mu can tell the energy card that was exhausted with energy at a glance. He can guarantee that although this energy card is old, it is an energy card that has never been used.

Moreover, the structure on this card is perfect and has no errors. It is much better than the one-star energy card made by Chen Mu himself. Such an energy card has absolutely no reason to be damaged.

But now the truth is that it really cannot provide any energy.

He inserted his energy card into the energy meter again, and the room returned to light. The energy meter was not broken, and he immediately excluded this external factor.

So what's wrong?

Under the light, Chen Mu looked at this energy card carefully.

As he rubbed the card with his hand, a guess suddenly rose from Chen Mu's mind. Could this be a waste card in itself?

A master can make a useless one-star energy card? It’s not a big possibility, Chen Mu pondered.

Carefully eliminate each factor, the structure is drawn correctly, there are no traces of use, no signs of energy loss, but it cannot provide energy.

Material? A flash of inspiration flashed in Chen Mu's mind, and suddenly he thought of the slightly thicker feel. The more he thought about it, the more he felt that it might be related to the material.

Chen Mu put the side of the card under the light and looked closely. He found something strange. The side of the card, which was less than a millimeter thick, had two extremely light-colored dividing lines. It turned out that this card was actually made of three materials. Since the colors of the three materials were very close, it was difficult to find it if it was not placed in front of you to look carefully.

Failed experimental product? It seems that this is the greatest possibility. Many years ago, a master wanted to make improvements to the one-star energy card, and it ended in failure. However, this failed experimental product was passed down for some reason and happened to be discovered by Chen Mu.

This seems to be the most likely speculation.

Chen Mu was a little disappointed. If this was the case, then this was worthless.

The finger subconsciously rubbed the edge of the card gently, and suddenly, the fingers felt something different.

Chen Mu quickly put the card in front of him again. I don’t know if it was too old, and the edges of the card had begun to peel off. Chen Mu, who had already lost interest in this waste card, suddenly became a little curious. If it really matched his own speculation, then the master must have thought that these three materials could improve the one-star energy card. Chen Mu had a clear understanding of his level, and his level was probably not as good as ordinary beginners. He had never accepted any formal learning in card making.

But he also has his own confidence, that is, the one-star energy card! From the beginning, he has only studied the one-star energy card, and he is so familiar with the one-star energy card that he is not familiar with. Since the last fine-tuning of the one-star energy card, there has never been any breakthrough. Today, this card gave him another inspiration. Since the structure cannot be broken through, why not try it in terms of material?

Since he had thought about this, Chen Mu became a little interested in the material of this experimental card. Although this experimental card is a waste, it is undoubtedly written by a master. Of course, knowledge in all aspects is not comparable to that of himself. It is precisely because of this reference in his heart that Chen Mu planned to carefully study the three layers of material that glued together.

Carefully uncovering the outer film that had begun to peel off, Chen Mu couldn't help but sigh that no matter how strong the material was, it would be difficult to preserve the glory of the past under the erosion of time.

When Chen Mu completely uncovered the film on the surface, he suddenly became completely stunned and stared at the card, as if he was struck by lightning, as if he was stunned!

The black card surface is as thin as the night, and hundreds of silver threads are as thin as hair, covering the entire card surface like a spider web. It seems messy, but at any small part, you can find graceful arc-shaped turns, rigorous structure, and incredibly complex nesting.

Although the silver lines are as thin as hair, it is a bit difficult to distinguish between naked eyes. It looks like a capillary in the human body, giving people the illusion that silver liquid is flowing slowly.

What is this? Is it a card?

Chen Mu murmured unconsciously, his brain completely fell into a semi-stagnant state.

It took him ten minutes to recover from this chaotic state. He rubbed his eyes hard and made sure that he was not dazzled.

My own speculation was completely deviated from the direction. What failed experimental product? This is obviously a card that was processed by disguise. With Chen Mu's limited knowledge, he naturally didn't know what kind of card it was. In fact, the complexity of this card far exceeded Chen Mu's cognition. Such fine lines and superb production craftsmanship were all things he had never seen before, and he had never even thought about it.

He has never seen those high-end cards at the acquisition station. Although they are all waste products, such complex and detailed cards are something he has never seen before.

What card is this? Chen Mu's curiosity is unprecedentedly high.

A large number of recommendation votes are urgently needed! Thank you!
