The ancient Chinese believed that everyone has an aura, and the aura is not constant, but is controlled by the aura of the universe. If the aura of man and the universe is harmonious, it is auspicious, and if the aura of the two sides is not harmonious, then it is fierce.

Therefore, with their experience and wisdom, the ancients depicted all the information of the universe at all levels that they had explored, such as the stars in the sky, everything represented by the five elements on the earth, and the heavenly and terrestrial branches.

In the hands of ordinary people, the compass is a dead thing, and it is of little use, but in the hands of a feng shui master, this compass is infinitely useful.

Most of the feng shui masters practice qigong inherited from the sect, using qi as a guide and infusing it into the compass, through the rotation of the magnetic needle, to find the most suitable direction or time for a specific person or a specific thing.

Lu Chen walked around the room and watched, although he had seen more than a dozen, he was not very satisfied.

A normal compass is composed of three parts: one is Tianchi, also known as the bottom of the sea, which is also the compass. The second is the inner disk, which is the disc that can be rotated immediately outside the compass. The third is the outer plate, which is a square, is the tray of the inner plate, and there is a small hole in the middle point of the outer side of the four sides, and it penetrates the red line to become the ten ways of Tianxin, which is used to read the content of the inner plate.

But the compasses he has seen have all kinds of flaws, either the Tianchi is crooked, or the inner disk is unknown, or the outer disk is loose, in short, they are all things that coax novices.

"May I ask Uncle Yang, do you have any advanced compasses here, I don't like these new compasses very much. ”

Lu Chen glanced at it a few more times and found that the compass placed on the bright side was all such scraps, useless at all.

"Children, it seems that you are knowledgeable, but unfortunately this high-end compass has become a collection of rich people, and there are very few that can appear on the market. ”

When Uncle Yang heard this, he shook his head helplessly and sighed.

Lu Chen smiled helplessly, most of these high-level compasses have been blessed by masters for a long time, and they can form a special aura, similar to the magic weapon that has been opened by Buddhist monks, and has wonderful uses such as driving away evil spirits and keeping peace.

It is precisely because of these wonderful uses that the compass has been transformed from a feng shui tool into a collectible at once.

"Uncle Yang, I remember that you still have one in your collection, take it out and show it to this Mr. Lu?"

Chen Haoxuan is not very interested in the things in the house, after all, his father is good friends with Uncle Yang, and he has long known that the things in this house are uneven, and most of them are fooling the novice Xiaobai, which is the same as the Taihexuan he opened.

"What, does Uncle Yang still have a compass in his collection?"

As soon as he heard this, Lu Chen became interested, since this Uncle Yang sells compasses and other feng shui tools, and I think he is also knowledgeable, then his collection is likely to be a high-grade compass, a real magic weapon.

"It's not that I don't want to take it out, it's just that the compass is missing a corner, and it's obviously a piece of waste, and it's useless at all. ”

Uncle Yang spread his hands and said helplessly.

Chen Haoxuan's sense of Lu Chen was not bad, and he wanted to help him with this, so he opened his mouth to persuade him again: "You can take it out, and give us a few young people to have a long insight, isn't it?"

At the request of Chen Haoxuan and Lu Chen, Uncle Yang had no choice but to nod, went to another room, and retrieved an object wrapped in red silk. When he untied the red silk, a slightly old compass came into everyone's eyes.

After Lu Chen saw this compass, a flash of light flashed in his eyes in an instant, and he immediately returned to normal.

Uncle Yang's compass collection, about 30 centimeters square, is slightly yellowed throughout, giving people a feeling of precipitation over the years, as well as a peculiar harmonious beauty. The only shortcoming, just like Uncle Yang just said, is missing a corner, which looks a little awkward.

"Lu Chen, how does this compass feel?"

Fang Yingling felt that the compass in front of her was too old and too long, and it was dirty, and it didn't look good at all.

"It's a good thing. ”

Lu Chen stretched out his hand and wiped the surface of the compass, and said in a deep voice: "The material of this compass should be a typical tiger bone wood. The so-called tiger bone wood, also known as white soapwood, has not grown to usable timber because of its slow growth, so it was cut down by the countryside as firewood, so the locals like to call it tiger bone firewood. Although tiger bone wood is not easy to become a talent, its material is shiny, the texture is straight, the structure is fine, it is not warped, and the corrosion resistance is strong, it is a rare tree species unique to the Huangshan region, and it is the top grade in the production of compass wood. ”

After hearing these words, Uncle Yang showed surprise on his face, and after looking at Lu Chen again, he exclaimed: "I didn't expect you to know so many things at such a young age, I don't know if the Venerable Master is the Feng Shui master?"

"It's purely self-taught, and I read books indiscriminately. ”

Lu Chen smiled faintly and said casually.

Uncle Yang has been in business for so many years, and he is naturally a human being, seeing that Lu Chen is reluctant to reveal too much, he also did not continue to ask.

"I think this compass is very good, and the material should be rosewood, so why don't we buy this one?"

Fang Yingling held up a compass that I didn't know where to turn it over, and said with a smile.

"No, this kind of rosewood is purely to deceive Xiaobai. ”

Lu Chen glanced at it and shook his head.

"Why can't it be?"

Fang Yingling was a little unconvinced, the compass she was holding in her hand, whether it was material or appearance, was many times better than the old compass with missing horns, I don't know how many times, why was it in Lu Chen's mouth?

Chen Haoxuan, Qi Jun, and Boss Mo on the side also looked curious, waiting for Lu Chen's popular science explanation.

Seeing this, Lu Chen smiled and explained to a few people: "Rosewood itself is not suitable for making a compass, because the value of wood and the effect of a compass are completely different concepts. The first condition for making compass wood is to protect against radiation, and rosewood is poor in radiation protection, which will cause the magnetic needle to be unstable. ”

"Normally, those compasses made of precious wood have characters carved on the inner disks about the directions, the sexagenary and the earthly branches, etc., while the real magic compass is handwritten. Manual engraving or mechanical engraving of the compass is purely commercial, saving trouble and effort, but it is not practical and, more importantly, has no collection value. ”

"The wood used to make the compass needs stability, and it is generally made of wood that is rigid and soft, and the closer it is to the rice paper, the better, such as the tiger bone wood I just mentioned, when written in ink, it is permeated up and down. And sandalwood, rosewood, sour branches and other wood, is infiltrated left and right, or even not penetrated for a long time, when the word is written, it also becomes a black spot......"
