  Chens heart skipped a beat as his fingers nimbly pulled out an Energy Star Card from among them and held it up in front of himself for careful examination.

  From the surface structure, this one-star energy card is nothing out of the ordinary, it uses the most widely used Bakks structure now, which is also the most common structure. However, Chen Mu still sensed a hint of abnormality in this card.

  Weight - This card is slightly heavier than a normal one-star energy card. Having produced tens of thousands of one-star energy cards, Chen Mu was all too familiar with the weight of a one-star energy card. Regardless of its structure, as long as it was a one-star energy card, its weight would not exceed a certain specific range.

  It is clear that the weight of this card is not within this range.

  Closing his eyes, Chen Mu lightly rubbed the surface of the energy card with his index finger and thumb, carefully feeling the slightly raised patterns on its surface.

  The texture is too shallow, floating and powerless, this feeling...this feeling... Chen Mu furrowed his brow, recalling this familiar yet unfamiliar feeling.

  Suddenly... Chen Mus eyes lit up abruptly - just like the result of being painted on a somewhat lighter material!

  But thats not right, Chen Mus mind couldnt help but raise even more doubts. From the feel of it, this one-star energy card had a very hard texture and a thick, heavy feel to it. According to general rules, the patterns etched onto it should have a stronger tactile sensation.

  How can I have such a feeling? Its really strange!

  After re-examining the energy card in his hand, Chen Mu still couldnt find out what was causing this strange phenomenon. The strokes were flawless, and from the smoothness and elegance of the brushwork, it was absolutely at a master level. Even though he had made one-star energy cards for three years himself, with his own skills, he couldnt draw such beautiful lines.

  This made Chen Mu even more puzzled. A Master-level one-star energy card, the statement itself was a bit strange, which master would go to make a one-star energy card? If it were a five-star energy card in his hand, Chen Mu would have felt more normal instead.

  After some thought, Chen Mu put this somewhat strange card together with the new structures one-star quantity card he had just discovered.

  Chen Mu finally finished his work and let out a long sigh of relief.

  He has been concentrating on his work all along and now feels a bit tired.

  "Ill take these two cards." Chen Mu Zhou raised his hand with the two one-star energy cards.

  "No problem, no problem." Xiao Hei said with a smile, he had quite a harvest today. Chen Mu helped him find five unused energy cards and his mouth was about to curve upwards in joy.

  In Xiao Heis heart, Chen Mu was a bit strange. Looking at his clothes, it was clear that he was from a poor family. People like him would never let go of any opportunity to save money. The unused energy cards in his hand were a small fortune in their eyes! However, Chen Mu strangely didnt care about the unused energy cards and instead took great interest in those one-star energy cards, which were all used up.

  Of course, these are just thoughts in his mind, and he cant wait for it to happen. If Chen Mu was normal, then the energy cards on his hands would not have fallen into his own hands, this is all money!

  On one hand, he was indulging in his own foresight at the time, and on the other hand, he was smiling and seeing off Chen Mu.

  Back home, it was already 10 oclock at night. After hastily eating something, Chen Mu couldnt wait to take out the two energy cards he had obtained today for study.

  The first card with one star energy made Chen Mus eyes light up.

  This was a structure he had never seen before, with intricate patterns made up of light blue lines that covered the entire card surface. The one-star energy card was the size of a poker card, with a slightly soft texture and a smooth card surface, but if you stroked it carefully, you could feel the raised pattern.

  Ordinary people see such a complex pattern, and they may feel dizzy and dont know where to start.

  Chen Mus eyes lit up. For three years, he had been facing similar patterns every day, although the structure was different from what was in front of him, but the complexity was not inferior. Those twelve new structures also gave him a lot of experience.

  To grasp the structure of a card, you must find its starting point, which is where the first stroke falls. Then, following the trajectory of the lines and delving deeper, it will be easier to understand.

  Although the one-star energy card was complex, it was the simplest among all cards. However, it wasnt until three hours later that Chen Mu truly understood the function of each stroke. But to create a similar one-star energy card, he would need a lot of practice. He gave up on this intention, as extensive practice meant extensive consumption, and at least for now, his modest savings were not enough to allow him to be so extravagant.

  Whats most important is that he has already calculated that the cost of a one-star energy card with this new structure would be slightly higher than what he currently produces. Spending a lot of money to practice a new structure that doesnt have any meaning for himself isnt his style. However, there are still some things worth learning from this energy card, such as its loop compression structure, which might be able to be incorporated into his own energy card structure.

  Chen Musui pondered, but his fingers involuntarily slid over another One-Star Energy Card. His gaze fell on the second newly acquired energy card.

  The drawing method of this one-star energy card is not unusual, it is the most widely used standard drawing method for one-star energy cards nowadays. However, what caught Chen Mus attention was the strokes on the surface of the card.

  The lines are beautiful and smooth, with a very pure tone, every turn and curve is full and round, with the brushwork of a master.

  This card looks quite old, obviously having been around for some years, probably an early work of a master. However, what first caught Ye Chongs attention was not these two points, but its weight and thickness.

  This worn-out one-star energy card is about a tenth heavier than an ordinary energy card. The weight of the one-star energy card itself is already very small, and even if its only a tenth, its hard to notice. However, Chen Mu made too many one-star energy cards, so when he first picked up this one-star energy card, he felt it. The thickness was also the case, this one-star energy card was slightly thicker than an ordinary one-star energy card.

  This is the biggest reason why this card caught Chen Mus attention. The One-Star Energy Card was one of the earliest cards to appear and also the most widely used, with its standard specifications already set at the beginning of its creation. Until now, what is known as the standard structure and standard materials have not changed much since its inception.

  A one-star energy card made by a grandmaster, how can there be such a difference?

  Could it be...

  Chen Mu naturally thought of the material aspect, could it be that this unknown master had found a new material for one-star energy cards? For his livelihood, Chen Mu had always been dedicated to reducing the cost of one-star energy cards, and this one-star energy card sparked his strong interest.

  The energy card was removed from the energy meter, and the room suddenly plunged into darkness.

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

  Huh? Not bright! The room is still pitch black, without a single ray of light.

  Chen Mu was stunned, how could it be possible that it wasnt shining?

  Impossible! This was the first thought that popped into Chen Mus mind. There were no signs of use on this card, and an energy card with depleted energy was something Chen Mu could identify at a glance. He dared to guarantee that although this energy card was old, it was an unused energy card.

  Moreover, the structure on this card is flawless and error-free, far surpassing Chen Mus own one-star energy cards. Theres no way a card like this could be damaged.

  But in reality, it really cant provide even a bit of energy.

  He reinserted his energy card into the energy meter, and the room was once again filled with light. The energy meter wasnt broken, so he immediately ruled out external factors.

  Whats wrong with it?

  Under the lamplight, Chen Mu carefully examined this energy card.

  Rubbing his hands over the card, a guess suddenly rose up in Chen Mus mind - could this be a useless card?

  Would a grandmaster really create a one-star energy card thats trash? This possibility is quite unlikely, Chen Mu sank into contemplation.

  Carefully excluding one by one factor, structural drawing method is correct, no signs of unused, no signs of energy loss, yet unable to provide energy.

  Material? Chen Mus mind flashed with inspiration, and he suddenly thought of that slightly thick texture, the more he thought about it, the more he felt it might be related to the material.

  Chen Mu placed the card sideways under the light and examined it closely, and indeed found a peculiar feature. The side of the card, which was less than one millimeter thick, had two extremely shallow dividing lines. It turned out that this card was actually made by bonding three materials together, and because the colors of the three materials were very close, it was difficult to detect without holding it up to the eye for a closer look.

  Failed experimental product? It seems that this is the most likely possibility. Many years ago, a master wanted to make improvements on a one-star energy card and ultimately ended in failure, but this failed experimental product somehow passed down and was coincidentally discovered by Chen Mu.

  This seems to be the most likely conjecture.

  Chen Mus heart sank slightly in disappointment, if it was really like that, then this waste card would be completely worthless.

  The fingers unconsciously lightly rubbed against the edge of the card, suddenly, the fingers felt something was off.

  Chen Mu hastily put the card back in front of him, not knowing if it was because of the long years, but the edges of the card had already begun to peel off. Chen Mu, who had originally lost interest in this useless card, suddenly became a little curious. If it really matched his speculation, then that master must have thought that combining these three materials could improve the energy card. Chen Mu had a clear understanding of his own level, and he was probably not even as good as an ordinary beginner, having never received any formal training in card-making.

  But he also has his own confidence, that is the one-star energy card! From the beginning, he has been studying only the one-star energy card, and he is really familiar with it. Since the last time he made a slight adjustment to the one-star energy card, there has been no breakthrough until now. But this card gave him another inspiration, if the structure cant be broken through, why not try the material?

  Now that he had this idea, Chen Mu became somewhat interested in the material of this experimental card. Although this experimental card was a waste product, it was undoubtedly made by a master craftsman, and its various aspects were not something he could compare to. It was precisely because he had this intention to learn from it that Chen Mu decided to carefully study the three layers of materials stuck together.

  Carefully uncovering the outer layer that had already begun to peel off, Chen Mu couldnt help but feel a sense of melancholy in his heart. No matter how strong the material was, it would be difficult to preserve its former glory under the erosion of time.

  When Chen Mu tore off the thin membrane on the surface, he suddenly froze, staring at the card as if struck by lightning, like a wooden statue!

  Like a black night, the black card surface is covered with thousands of silver lines as thin as hair, like a spider web, seemingly chaotic but revealing elegant curves and turns, rigorous structures, and complex nesting that seems unbelievable.

  Although the silver lines are as thin as hair, it is a bit laborious to distinguish them with the naked eye. However, they seem to have fine blood vessels like the human body, giving people an illusion that a silver liquid is flowing slowly.

  What is this? A card?

  Chen Mu muttered unconsciously, his brain had fallen into a state of semi-stagnation.

  It took him a full ten minutes to recover from this bewildering state. He rubbed his eyes hard, making sure he wasnt seeing things.

  His own speculation had gone off in the wrong direction. What a failed experiment, this was clearly a card that had been disguised and processed. With Chen Mus limited knowledge, he naturally didnt recognize what kind of card this was. In fact, the complexity of this card far exceeded Chen Mus understanding, such fine lines, such superb craftsmanship, were all things he had never seen before, not even in his wildest dreams.

  At the acquisition station, those advanced cards he had seen before, although they were all discarded products, but such complex and delicate cards were something he had never seen before.

  What kind of card is this? Chen Mus curiosity was unprecedentedly high.
