After knocking on this guqin for a while, Fang You still didn't find a sound of a hollow, which made him a little puzzled, could it be that he guessed wrong, this was not something hidden, but a material used in the repair of the Song Dynasty.

If there is really something hidden in it, then he really sighs a little about the sealed surname of this guqin.

Fang You didn't give up, this guqin is so weird, it must be an extraordinary thing, otherwise, an ordinary guqin would not be so weird at all.

After activating the escape technique, Fang You continued to tap the body of the piano while staring at the guqin, and the still cyan aura that flashed in front of him was mixed with some yellow aura.

When some of the yellow aura is free, it merges with the cyan aura, turning into a green and yellow color like wheat that is about to ripen, which looks very beautiful.

Fang You's eyes looked at these aura, and he sighed a little, to be able to spread from the Spring and Autumn Period and the Warring States Period to the present, this guqin must have gone through a lot of tribulations, if he can't discover the secret in this guqin, he can only take it back to Huaxia and let Chu Lao and a few old men study it together.

Even if it is really not a famous qin, this well-preserved Warring States guqin alone is an incomparably precious national treasure-level cultural relic.

At this moment, Fang You's face moved slightly, his eyes were firmly fixed on the cyan aura that emerged from the guqin, and when he was concentrating on these beautiful aura just now, he suddenly felt that the color concentration of this cyan aura was a little different.

It was not the intensity of the aura, but the concentration of the color, Fang You's eyes widened, and he stubbornly observed every wisp of aura, and then compared.

Suddenly, he noticed the difference, and sure enough, the color of the cyan aura was a little different, some of the cyan aura was obviously darker, and some of the cyan aura was slightly lighter.

This phenomenon has never been found in other antiques, and some are only different colors, not the same color, with different concentrations.

Fang You looked at this guqin, but his face was a little eager to try, this guqin became more and more strange as he observed deeply, there was a yellow aura in it before, he couldn't find where to store things, he didn't expect that this problem had not been solved, and the next problem was discovered by himself.

The difference in color represents the difference in age, the difference between two different colors is hundreds of years, and the difference in color concentration also represents the difference in time, but the time gap is not as big as the previous one.

These two cyan auras with different concentrations could not be discovered at all without careful observation, which was also the reason why Fang You had not discovered them before.

According to his estimate of the color concentration, the age difference between these two cyan auras will not exceed a hundred years, since this guqin was made in the Spring and Autumn Period and the Warring States Period, could it be that it was repaired in that era.

Fang You shook his head, threw some messy thoughts out of his mind, and then began to observe the whole guqin closely, he wanted to see where this cyan aura of different colors came from.

At this time, Fang You did not complain that he did not get the Wood Escape Technique, because this was something he could not control, with the Wood Escape Technique, he could naturally discover the secrets in the guqin very simply, but without the Escape Technique, all he could do was to work hard to discover the secrets, with all the means he had now.

Gradually, he found two different positions of aura, the lighter cyan aura, which is free from the front of the qin, this front is not the entire upper part of the guqin, if the guqin is divided into three parts, then the light color is free from the upper part, and the remaining dark cyan air flow is free from the middle and lower parts.

Fang You looked at these two different aura, different positions, and fell into thought, since this is the case, the only thing he is sure of now is that this qin surface was only combined with the guqin long after this guqin was made.

If the surface of the piano is broken, then naturally the entire upper part of the guqin will be replaced, why is there now two different cyan aura emerging on the upper part of the piano surface.

Moreover, Fang You found that those yellow auras appeared at the junction of these two cyan aura.

After thinking for a while, Fang You smiled slightly, in this way, his previous guess has slowly become certain, there must be something hidden in it, and looking at the thickness of the surface of this guqin, he can be sure that this is not the true face of the guqin that he determined before, perhaps, the true face of this guqin is hidden inside.

When he was striking just now, there was no emptiness, which made him very amazed by the sealing technology of the guqin, and what made him have some doubts was the yellow aura inside, perhaps in the Song Dynasty, someone discovered the secret of this qin, so that he put in some things of that era, this is the only understandable explanation.

However, all of this is just speculation, even if he was very sure before, what the final result would be, he still had to wait until he discovered the secret of this guqin to be able to truly determine.

Fang You looked at the location of the junction of the two aura, and then slowly studied the possible mechanisms in the entire guqin.

In the meantime, he injected the gray air flow into it, wanting to see if this guqin was like the Chengying Sword, which needed internal strength or something to urge.

In the end, there was no reaction, and there was no sound of the mechanism opening on the guqin, Fang You slowly closed his eyes, wanting to attach his mind to the gray air current, and then entered the qin to watch, as if he looked at Xie Shuyuan and Ye Yuqing's bodies in the same way.

However, his mind couldn't enter the guqin at all, Fang You looked at this guqin, and couldn't help but smile, the previous Taobao leaks, even if there were some difficulties in the front, they could be solved quickly, and then it was smooth sailing, just like the Chengying Sword, but when he opened the mechanism in the early stage, he encountered a little trouble, and after that, he opened the Chengying Sword with a gray air flow.

And now this guqin, but it really stumped him, Fang You felt a surge of determination in his heart, he is not the kind of person who gives up when he encounters a little difficulty, over the years, he has encountered a lot of difficulties, even if he has a retreat technique, he has also encountered a life and death crisis, but no matter how difficult it is, he has not given up.

Then, Fang You began to carefully observe every position of the guqin, from the Chengying Sword, he clearly knew the magic of craftsmen in the Spring and Autumn Period and the Warring States Period, who were able to create a mechanism that opened with true qi, and even when the true qi flowed in, blue light would appear, which was already ingenious.

When it comes to the art of organs, only the Spring and Autumn Period and the Warring States Period were the most prosperous, when there was Lu Ban, who was called the ancestor by later generations of craftsmen.

Lu Ban is one of the most outstanding inventors in China, and his contribution to ancient times is no less than that of Albert Einstein in modern times.

Now, some of the tools used by the craftsmen and masters were invented by Lu Ban, the world's first nominal lock, it can be said that Lu Ban invented, there were locks created before, but the earliest locks had no mechanism at all, just made into tigers and other ferocious animals to scare away thieves.

Lu Ban, on the other hand, installed a mechanism on the lock so that it could only be opened with the corresponding key, so he replaced the human guard.

There are even historical records that Lu Ban also invented a wooden bird that can fly in the air, and in the Spring and Autumn Period and the Warring States Period, it can be described as an era when a hundred schools of thought contended and countless outstanding talents emerged.

One of them comparable to Luban is Mozi, the founder of the Mohist family, who created a set of theories of geometry, physics and optics during the Spring and Autumn Period and the Warring States Period and the Pre-Qin Period.

Together with Confucianism, it is known as Xianxue, and among the hundreds of schools of thought at that time, Confucianism was the most influential existence, and it was known as non-Confucianism.

It can be said that in terms of achievements, Lu Ban and Mozi are on par, and they are both the most outstanding craftsmen in the Spring and Autumn Period and the Warring States Period.

Just from the tomb of Qin Shi Huang and the mechanism of other tombs in ancient times, it can be seen that the magic of ancient mechanism technology can be seen.

When observing the Yueshan of this guqin, he suddenly found some suspicions, the Yueshan of the guqin is the most important part of the guqin, and it is also the highest position, its main role is to set the strings, and it is also the hardest position on the whole body.

Fang You found that this Yue Mountain could be gently shaken with a little force, but this shaking was not obvious, and the strength used was slightly weaker, so these Yue Shan made of hardwood did not move at all.

At the beginning, Wube Siren used to auction the Song Dynasty guqin of the French treasure of the Kojima National Book, he could study it for a long time under the explanation of Chu Lao, this Yueshan is an important position for the strings, and when the strings are played, it can be said that the most stressed part of the whole body.

No matter how the Yue Shan on the Song Dynasty guqin shakes, it is not moving, if there is a slight shaking, then the whole sound of the piano will also change, so in ancient times, I have only heard of playing the broken strings, and I have never heard of the saying of playing the broken Yue Mountain.

However, if someone gets this guqin, I am afraid that when playing the qin, the strength used is very gentle, and this strength cannot make the Yue Shan on the guqin shake in the slightest.

This mountain can be shaken, whether it is because of the long history and some dilapidation, or the seven mountains used to set up strings are the organs in the guqin.

If it weren't for the yellow aura inside, as well as the two different cyan aura, Fang You wouldn't think that this guqin had a secret existence at all, but the existence of these two auras showed the weirdness and mystery of this guqin.

Fang You carefully pinched the first Yueshan, then shook it a few times with a little force, and then shook each of the seven Yueshan a few times one by one, but the guqin still did not change at all.

Looking at this guqin, Fang You smiled helplessly, even if he took it back to Huaxia, how could he tell Chu Lao, just say that he felt that there was a secret in this guqin, and he needed to study it, so it would be too inevitable to have a meaning that there were no three hundred taels of silver here.

Thinking of his constant Taobao leaks, Chu Lao's words, Fang You was not worried, but worried that the rest of the people would have some unnecessary speculation.

If there is no aura, with his observation, he will not feel that this guqin has a secret, and it is determined that there is something hidden in it, but he can't find the location of the organ at all, and ordinary people may think that this is a guqin without secrets, such obvious suspicions, many people can have some doubts about him.

Fang You looked at this Yue Mountain, Yue Mountain is very hard, it can be preserved until now, it should not be shaken with time, then, it is very likely that there is a mechanism on it.

Seeing that Fang You kept observing back and forth on the guqin, and shaking some places from time to time, Matsumoto Mingdao and the others were completely dizzy, and they didn't understand what Fang You was doing.

Just now I said that this guqin is a treasure, but at this time, I was groping back and forth on the guqin without any scruples.

However, Matsumoto Mingdao and the others didn't bother Fang You at all, just watched carefully from the side one by one.

Fang You discovered the ability of the treasure, they admired it very much, and found the three-legged golden crow made of precious Loulan desert jade in the small island country, and found the Qi Nan agarwood that Wube Siren did not find, and in the end, they got two national treasures of the small island country.

And Fang You was still groping, and in the end, he couldn't help but shake his head, remembering some of the previous experiences of opening the Chengying Sword, and opening the Chengying Sword was also because he was in the black market auction, due to the sudden appearance of the Golden Escape Technique, he saw through the bronze sword full of patina, and thus saw the hidden sword inside.

This guqin, but he has never seen through, but through the aura, he knows that there may be secrets in it, he can't help but sigh secretly, the Chengying Sword needs the internal strength of the martial artist to open, this guqin, if it also needs internal strength, it would be good.

Suddenly, thinking of the words in his mind just now, Fang You came back to his senses violently, and kept pondering, the sword, the internal strength, and the guqin .......

The sword is a weapon, and the internal strength of the warrior complements each other, and the guqin, is a representative of the splendid culture and art, naturally different from the sword of the main martial arts, then the mechanism on the Chengying sword needs to be opened with the internal strength of the warrior, can it be said that this guqin, need the breath of the literati to open.

Could it be that hundreds of scholars sprayed up in one breath, Fang You fell into imagination, looking at Yue Shan used to set the strings, and then thinking of the shaking of Yue Shan before, as well as the wonderful mechanism in ancient times, his face couldn't help but change, this guqin mechanism, shouldn't it need to be played to be able to open.

This thought that flashed in his mind couldn't help but make Fang You a little incredible, anyone who heard such an idea would feel very absurd.

However, Fang You knew that the mechanism on the Chengying Sword was not the same incredible in everyone's eyes, and the formlessness of the Chengying Sword was the same, so it was really not surprising that this mechanism that needed to be opened by playing the piano was really a little surprising compared to the magic of the Chengying Sword.

"Matsumoto, please go buy seven strings, well, no, buy double, fourteen, to get the best, the most durable." Since he had this idea, how could it work without experimenting with it, Fang You suddenly came back to his senses and said to Matsumoto Mingdao on the side.

"Mr. Li, please wait, I'll be back soon." Matsumoto Mingdao nodded, and without asking Fang You the use of buying strings, he stood up directly from the sofa and walked towards the door.

Looking at the doubts on the faces of the remaining people, Fang You shook his head and smiled, now that he has no results, he really can't explain some of his discoveries to these people, even if he says it, these people won't believe it, only with real results can he explain everything, and only then can he make everything incredible before truly become a reality.

"The nearest piano shop, how far away is it?" After waiting for about ten minutes, Fang You couldn't help but reply to a few people on the sofa.

One of them replied with a respectful face: "Mr. Li, the nearest piano shop is not far away, but according to your request, the shop with good string quality is some distance from here, and the strings born by our small island country Toba House Co., Ltd. are special silk strings for guqin, and the quality is very good, and it is untangled, but looking at the current time, Matsumoto-kun should be back soon." ”

Fang You nodded, he was no stranger to the Toba House, but he had some impressions, when he was studying the Song Dynasty guqin before, he had heard Chu Lao explain, at that time, there were strings on the Song Dynasty guqin brought by Wubu Siren, Chu Lao just touched it with his hand, and said that this was the silk string of the Toba House in the small island country, but compared to the silk strings produced in China, there is more than tenacity and insufficient bone strength.

As the birthplace of guqin culture in China, there are naturally many shops that produce guqin including strings, the most famous of which is the ancient silk strings, compared to the small island country of Tobaya, the ancient silk strings are famous at home and abroad, and are popular with some guqin lovers.

After that, Chu Lao found a few primeval silk strings, and played the same song with the silk strings of Toba House, and with Fang You's keen sense, he could naturally distinguish the difference between the two strings.

However, now the guqin celebrity who specializes in the production of Taigu silk strings is old and no longer makes strings, and if he wants Taigu silk strings, he can only buy them from others, or see if some piano stores have stock.

In a small island country, it is not as good as Huaxia, and it is not bad to use the silk strings of Tobaya, besides, this time it is just to discover the secrets in the guqin, not to play it specially.

In the Song Dynasty guqin, Fang You did not just follow Chu Lao to study the guqin, but also played it for a while.

With his super learning ability, he quickly mastered the key points of guqin playing, and his control and grasp ability is far stronger than ordinary people, coupled with his peaceful state of mind, the timbre played is very beautiful, almost even Chu Lao and other old men are addicted to it.

Naturally, in the end, they can't help but sigh at Fang You's learning ability, in their opinion, even if they are pianists who have been learning the piano for decades, they may not be fascinated by Fang You's playing.

The experience of following Chu Lao to learn the piano was also the confidence for Fang You to directly ask Matsumoto Mingdao to find the strings when he discovered the secret of Yue Mountain.

If he didn't have such an experience, just by playing indiscriminately, Fang You felt that this mechanism would not be opened at all, unless it was just a blind cat encountering a dead mouse.

As the member of the Dragon Shadow Tomb Raiders said just now, sure enough, after more than ten minutes, Matsumoto Akido hurriedly returned to the room, carrying a bag in his hand. (To be continued.) )
