The ancient Chinese believed that everyone has an aura, but the aura is not constant and is controlled by the aura of the universe. If the auras of the person and the universe are in harmony, it is auspicious. If the auras of the two sides are not harmonious, it will be auspicious.

That would be fierce.

As a result, the ancients relied on their experience and wisdom to describe all the information they had learned about the universe at all levels, such as the stars in the sky, everything on the earth represented by the five elements, the heavenly stems and the earthly branches, etc., on the compass.

In the hands of ordinary people, the compass is just a dead object and of little use, but in the hands of a Feng Shui master, this compass has infinite uses.

Most Feng Shui masters practice Qigong inherited from their sects. They use Qi as a guide and pour it into the compass. Through the rotation of the magnetic needle, they can find the most suitable position or time for a specific person or a specific thing.

Lu Chen walked around the room and looked at it. Although he had already looked at more than ten, he was not satisfied with any of them.

A normal good compass consists of three parts: the first is Tianchi, also called the seabed, which is the compass. The second is the inner disk, which is the rotatable disk immediately outside the compass. The third is the outer disk, which is square and is the inner disk.

The tray has a small hole at the midpoint of the four outer sides, and the red lines are inserted into it to form the ten channels of Tianxin, which are used to read the contents on the inner disk.

But the compasses he had seen had various flaws. Either the Tianchi was crooked, the inner disk had unclear writing, or the outer disk was loose. In short, they were all things to deceive novices.

"I would like to ask Uncle Yang, do you have any more advanced compasses here? I don't really like these new compasses."

Lu Chen glanced at it a few more times and found that the compasses displayed on the surface were all such scraps and were of no use at all.

"Kid, it seems you are knowledgeable. Unfortunately, these higher-end compasses have become collectibles for rich people. There are very few of them on the market."

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

Lu Chen smiled helplessly. Most of these advanced compasses have been blessed by masters for a long time. They can form a special aura, similar to the magical instruments that have been illuminated by Buddhist monks. They have the ability to ward off evil spirits.

It has wonderful functions such as keeping safe.

It is precisely because of these wonderful functions that the compass has been transformed from a Feng Shui tool into a collectible. No matter whether it is useful or not, just put one at home first.

"Uncle Yang, I remember you still have one in your collection. Can you show it to Mr. Lu?"

Chen Haoxuan is not very interested in the things in the house. After all, his father has a good relationship with Uncle Yang and has long known that the things in this house are uneven and mostly used to deceive newbies, just like the Taihexuan he opened.

"Why, does Uncle Yang also have a compass in his collection?"

Upon hearing this, Lu Chen became interested. Since this Uncle Yang sells compasses and other Feng Shui tools, and presumably he is knowledgeable, his collection is probably a high-end 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. It's obviously a piece of waste and of no use at all."

Uncle Yang spread his hands and said helplessly.

Chen Haoxuan had quite good senses about Lu Chen and wanted to help him, so he persuaded him again: "Just take it out and treat it as a long-term experience for us young people, okay?"

At the request of Chen Haoxuan and Lu Chen, Uncle Yang had no choice but to nod his head, went to another room, and took back an object wrapped in red silk. When he unwrapped the red silk, he found a slightly old compass, and that was it.

caught everyone's eyes.

After Lu Chen saw the compass, a flash of light flashed in his eyes, and then returned to normal.

Uncle Yang's compass collection is about 30 centimeters square. It is slightly yellowed throughout, giving people a sense of time and a strange harmonious beauty. The only shortcoming is just like what Uncle Yang said just now.

It looks a bit awkward, with a corner missing.

"Lu Chen, how do you feel about this compass?"

Fang Yingling felt that the compass in front of her was too old and too old. It was rusty and not good-looking at all.

"This is a good thing."

Lu Chen reached out and wiped the surface of the compass, and said in a deep voice: "The material of this compass should be typical tiger bone wood. The so-called tiger bone wood, also known as white soapwood, has not grown enough to be used due to its slow growth.

The wood was cut down for firewood in rural areas, so the locals like to call it tiger bone firewood. Although tiger bone wood is not easy to grow, its material is shiny, straight texture, fine structure, does not warp, and has strong corrosion resistance. It is the local name of Huangshan.

The unique and rare tree species is the best quality wood for making compasses."

After hearing these words, Uncle Yang showed a look of surprise. After looking at Lu Chen again, he praised: "I didn't expect that you know so many things at such a young age. I didn't know that my respected master is that Feng Shui master."

?”

"I'm purely self-taught and I just read it randomly."

Lu Chen smiled faintly and said something perfunctory.

Uncle Yang has been in business for so many years and is naturally a good person. Seeing that Lu Chen was unwilling to reveal too much, he wisely did not continue to ask further.

"I think this compass is very good. It seems to be made of rosewood. Why don't we just buy this compass?"

Fang Yingling held up a compass that she found out from somewhere and said with a sweet smile.

"No, this kind of rosewood one is just to deceive Xiaobai."

After Lu Chen glanced at it, he shook his head.

"Why can't it work?"

Fang Yingling was a little dissatisfied. The compass she was holding in her hand, both in terms of material and appearance, was many times better than the old compass with missing corners. Why didn't it work in Lu Chen's mouth?

Where is it?

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 the confusion of several people: "Rosewood itself is not suitable for making compasses, because the preciousness of the wood and the effect of the compass are two completely different concepts. The first step in making compass wood

One condition is to protect against radiation, and rosewood is poor at protecting against radiation, which can cause the magnetic needle to be unstable."

"Usually, for compasses made of precious wood, the characters on the inner disk regarding directions, celestial stems, and earthly branches are mostly carved, while the real compasses are written by hand. The compasses are manually carved.

Or mechanical engraving, which is purely for commercial reasons and saves time and effort, but has poor practicality and, more importantly, has no collection value."

"The wood used to make the compass needs stability. Generally, it is made of wood that is hard but soft. The closer it is to rice paper, the better the effect. For example, the tiger bone wood I just mentioned, when written on with ink, it penetrates up and down. And
