Because of the cultivation of the "Ancient Five Fowl Opera", Fang Yu's five senses were much more sensitive than ordinary people, and it was quiet in the early hours of the night at this time, so even through a thick wooden door, Fang Yu still heard a faint sound outside the door.

At this time, in such a murderous mansion, it stands to reason that there could be no other sounds, Fang Yu had some doubts in his heart if it was a mouse or a night cat, but he was not sure. In order to avoid accidents, Fang Yu did not rush to open the door, but walked to the door of the attic and quietly listened to the movement behind the door.

Because the "Cormorant Feather Feather" formula had not yet been completed, Fang Yu's sense of hearing had not yet transformed into a transcendent instinct like his sense of taste and smell, but if he temporarily strengthened it with Yuan Force, he could barely collect the movement within ten meters of the surrounding area through the door.

The sound coming from outside the door was a small "brushing" sound, somewhat like the sound of two clothes rubbing, coming and going. There is some rhythm when it appears, and other strange muffled sounds when it stops.

Fang Yu listened for a while, and was about to quietly open the attic door, sneaking a peek out, and when he looked down, he saw a flash of light at the crack in the door on the lower edge of the attic's wooden door.

"Anyone?"

Fang Yu immediately stopped what he was doing, took a few steps back, prepared for more than ten seconds, and slightly adjusted the output of the yuan force to the auditory. Then he closed his eyes and carried a stream of Jin Xingyuan force to rush up to his nose, making a "hum" sound.

This sound was low and long, not loud, but it produced a large number of sound waves that could not be heard by ordinary people, penetrating the door panel in front of him and spreading into the space behind the door.

This is an extended application of Fang Yu's small magical power "gathering and dispersion" obtained after breaking through the "Honghu Fen Wings". When he was fighting with the little man Wu Kun that day, Fang Yu was blessed with Dao power by Wei Zhen in the air, and temporarily improved a realm, and he used this trick before, but he used infrasound waves at that time.

After practicing to Dacheng, not only does it not need to be converted by the earth's elemental force, it can continuously generate a steady stream of gold and elemental power, and it can also freely control the transformation of the airflow in the body.

Some people may wonder why the lungs of the human body are gold, which will produce gold Xingyuan force, and no matter how you look at this organ, it has nothing to do with metal. In fact, there is a problem of how to understand the "five elements".

In ancient China, the law of change in nature was summarized as the "five elements", which is known to many people as gold, wood, water, fire, and earth. However, most people do not understand the true meaning of the "five elements", and almost all of them simply think that they refer to the five types of substances that exist in nature. In fact, this is a huge misunderstanding.

"Shangshu Hongfan" says: Five elements: one is water, two is fire, three is wood, four is gold, and five is earth. The water is said to be moist, the fire is said to be hot, the wood is said to be straight, the gold is said to be from the leather, and the soil is said to be cropped.

This clearly explains the law of change of things represented by the "five elements", and there is no half word that connects the "five elements" with concrete matter.

Of course, later the ancients did use five specific substances to explain the "five elements", but that was just to help ordinary people understand intuitively, not that the "five elements" were just five things.

Taking the "gold" in the "Five Elements" as an example, "Jin Congge" refers to the fact that the change of things will inherit the past achievements and become a solidified reality, and at the same time, it will also change its form due to the change of conditions. That's why "gold" is used to refer to this law, because in common substances, metals have similar characteristics, which can be rigid or flexible, and can be very strong, but can change into different forms under certain conditions. However, the "gold" in the "Five Elements" is by no means a simple metal, otherwise the gold in the Five Elements cannot be explained, and the metal cannot be turned into water.

Of course, some people say that heating metals to reach the melting point is not gold and water, but such "five elements" are completely understood as the basic knowledge of physical chemistry. If that's all there is to it, why did the ancients spend so much time studying and studying?

The reason why the "Five Elements" can be misunderstood is largely due to the influence of the Western Four Elements Theory. The Western theory of the four elements summarizes the world into four basic forms, which are called "earth, fire, feng shui". It is easy for people to use the same idea to apply the theory of the "five elements", and it is easy to simply regard the "five elements" as a specific substance.

However, the wise men of the East and the West also have some tacit understanding, such as the "gold line" in the "Five Elements", in fact, the ancients preferred to use "qi" to refer to it, and only because it is convenient for beginners to understand that tangible and qualitative metals were chosen.

"Qi" disperses is formless and substantial, and gathers into clouds and water, which is also in line with the meaning of "Congge", which is why the ancients determined that the lungs in charge of breathing air flow belong to gold. The Jin Xing Yuan Power generated through the internal cultivation of the inner body could not make Fang Yu become a "Magneto", with the ability to control metal, but it gave him more flexible and ingenious magical powers.

Although Fang Yu could only use the Jin Xing Yuan Force to fine-tune the density and vibration frequency of the air flow in his body because of the relatively large constraints on transcendent power in this world, the extended use effect was unexpectedly excellent. Infrasound waves can damage enemies, and ultrasound waves can be used for reconnaissance and detection, both of which are very convenient.

Today, Fang Yu felt the benefits of Jin Xingyuan's power, and as the ultrasonic waves he sent out were reflected back when they encountered objects, the general situation behind the door was presented in Fang Yu's mind.

To Fang Yu's surprise, the outside of the attic was not the villa aisle he imagined, but in a room. There were rows of tall cabinets in the room, and large tables and chairs... Fang Yu immediately understood what room was opposite the door, it was Shen Jiading's study.

The ultrasound that is now reflected back shows that there are two obvious contradictions in the study—two vertical and irregular rectangles of different lengths.

"Two people!"

Fang Yu judged the true face of these two rectangles based on his previous experience of trying this ability.

The two of them also seemed to hear some of Fang Yu's slight voices when he activated his ability just now, after all, it was the dead of night now, and the slightest sound would be obvious. From the last few reflections of the sound waves, Fang Yu "saw" the two rectangles that seemed to be preparing to approach the attic door.

Fang Yu looked around at the attic and frowned, there was no place to hide around. Unless he left through the window immediately, Fang Yu would have to take a risk if he wanted to enter Shen Jiading's study.

He went back to the attic, closed the window, and then took down a picture of the decorative figures hanging from the attic, and placed it at the corner at the end of the attic staircase, while he hid himself above the staircase.

The two men must have approached the attic doorway, as the light from their lighting tools was already clearly visible at the crack in the door. Fang Yu heard a slight sound of metal colliding and rubbing, it should be the two people who opened the door.

After a while, a beam of light shot up from the stairs at Fang Yu's feet, followed by a second beam, and the two of them carefully followed the stairs up the attic while shining around with flashlights.

When the two of them walked to the middle of the stairs, their figures finally appeared in front of Fang Yu's eyes. Fang Yuyun used his eyes to carefully examine these two people in the dark.

Both of them were quite thin, one was taller and wore a T-shirt and jeans of unknown color, and the other was a little shorter and wore a tracksuit. Both of them were wearing sneakers on their feet, and they had a layer of cloth tied to their shoes, and the sound under their feet was very soft. Now Yu understood what the rhythmic "brush" sound he had just heard was.

When the two of them were about to walk up to the attic, the one in a T-shirt who walked in front happened to have a flashlight sweeping to the decorative figure that Fang Yu had placed at the top of the stairs, and the figure on the portrait seemed to come alive under the strong light, and was looking at the person with a smile.

"Ahh

The tall man in the T-shirt was so frightened that he almost threw the flashlight out of his hand.

"Shut up"

The one in a tracksuit who followed him immediately covered his mouth:

"Shhhh

The tall man in the T-shirt took off the hand of the tracksuit and tracksuit, pointed to the place where the painting had just been, and said in a slightly trembling voice:

"Look, there's someone."

Tracksuit pointed the flashlight at the finger of the T-shirt, glanced at it, and was also startled by the painting, but he was a little bolder than his companion and quickly discovered the problem.

"Damn, it's a painting."

"Is it a painting?" The T-shirt held up the flashlight in disbelief and looked at it again before breathing a sigh of relief.

"I'm scared to death, who left this painting here, it's so hateful, anyone who sees it at night is scared."

The sportswear said angrily: "Don't worry about this, since you have come up, hurry up and search for anything valuable." ”

While the two were talking, Fang Yu used his finger to pop out the nail that had just hung the painting. The nails flew directly to the bookshelf on the left side of the attic, making a slight sound and falling to the ground.

The two of them had just been startled, but now they had relaxed, and they heard a clear sound in the dark room, and immediately their hairs stood on end, and their flashlights pointed at the bookshelf at the same time.

As the flashlight shifted direction, the staircase behind the two men fell back into darkness with no fingers visible. Fang Yu was waiting for this opportunity, he immediately jumped down from the top of the stairs, and when he was in the air, his palm was attached to the wall of the stairs and gently used the earth element force to form a suction, buffering the power of his landing.

As soon as he landed, Fang Yu gently clicked on the stairs, quickly passed through the attic door, and hid in the study behind the door.

All the attention of the two men was seized on by the sound of the attic bookcase, and they did not notice a large living person passing three or four paces behind them.

Fang Yu entered Shen Jiading's study and found that the floor was covered with a thick and soft carpet, and there was almost no sound when stepping on it. Fang Yu secretly called it a fluke, if it weren't for the two people who tied strips of cloth on their feet just now, and as a result, they rubbed against the carpet and made a sound, then he might have walked out directly and collided with them.

Fang Yu gently closed the door of the attic and walked around Shen Jiading's study quickly. It is estimated that it has been swept by the police before, and there is almost nothing on the surface of the desk or in the drawer of the desk.

On the wall behind the desk was a camera obsca that had been opened, the one they had opened. The inside was also clean, leaving nothing for Fang Yu.

Fang Yu was a little disappointed, but this was also expected, even if there was something, it was estimated that it would fall into the hands of the two stupid thieves in the attic. Fortunately, the books in the study are still there, which is what Fang Yu focuses on.

Fang Yu walked to the bookshelf, and as he expected, Shen Jiading's bookcases were also numbered and placed according to standard book management methods, which was very unusual in ordinary people's homes. Especially when the number of books is not too much, if this practice is not some kind of obsessive-compulsive disorder, it is deliberate.

Shen Jiading's collection of books is much more than that of ordinary rich people, and half of the spacious study room is full of bookcases, which can probably have thousands of books, and there are many disciplines covered in it, but even this is far from being comparable with the library. Therefore, each of Shen Jiading's bookcases contains several categories of books, and the books of the same category occupy a movable book compartment according to their number.

Fang Yu was a little excited, quickly browsed the numbers in front of the bookshelf, and quickly found the book grid on the corresponding bookshelf according to the combination of characters and numbers left by Shen Jiading.

There are quite a few books on this book, about a dozen, including the one Liu Zhenqiang has read. There is also an obvious space in this row of books, which looks like someone has taken the book away. Fang Yu's heart moved, he took out the book he got from the attic and inserted it inside, the thickness was just right, it seemed that this book was from this book. It seems that the last person to read a book in the attic should not be his outer room, but Shen Jiading himself.

According to the string of characters and numbers left by Shen Jiading, two books that were quite related were found in the Shudu Library and his study room, if it was a coincidence, Fang Yu felt that this was really too coincidental. But it was not a coincidence, Fang Yu couldn't figure out the trick for a while.

Verifying his conjecture, Fang Yu carefully put away the book and prepared to leave the study to go to other rooms to have a look. Then the door to the attic opened, and the two men came down from above. Fang Yu dodged and hid behind a bookcase, looking at the two through the gap in the bookcase.

"Phew, there's nothing of value at all, and it made me eat a stomach full of ashes."

The little man in the tracksuit walked out in a muffled voice, and the tall man in the T-shirt grumbled as he followed.

T-shirt looked at the rows of bookcases and said angrily:

"This study is also, obviously it looks like a rich person's place, but there is not even a gold pen, except for books are books, I am angry and packed these books and carried them back to sell, so I can't go back empty-handed."

As he spoke, he walked to the bookcase, and Fang Yu became nervous.

"If you want to pack it, my hand style has not been smooth these days, and I will bring back a bag of books, but I am afraid that I will lose home." Sportswear said angrily.

Listening to the words of the little man, the T-shirt hesitated and gave up.

"It's really unlucky, it seems that I came for nothing today, let's go, Brother Xing. I don't know if the wooden book I found just now is a cultural relic, and if I can buy it. He couldn't help but babble as he walked out of his tracksuit.

"Book of wood!" Fang Yu almost suspected that he had misheard, could it be that what Huyan had not found would be taken by these two thieves?
