It's a five-pointed star-like shape, and the corners on either side are drawn in a downward sloping arc instead of a straight line. The front corner is much longer than the others, and the top is very sharp and pointed, like a signpost to the left. I looked at it in a trance, and this five-pointed star was too strange. But there is always a vague sense of déjà vu, but I can't remember where I've seen it.

I asked the old cat, is this symbolic pentagram showing us the way? Signal us to the left?

The old cat lay on the ground and sniffed next to the symbol, then got up and explained to us that this should be a "star", which was also called the star in ancient times. The one that stands taller than the other four corners is the direction of the way. According to Lao Mao, this mark was often used as a guide for subsequent teams when the two armies clashed in the Cold Weapon Era. It is usually done with a potion of a trait, marked on the ground by the drummer in the army. This potion keeps the Guiding Star from despairing for a short period of time and is resistant to wind, rain and sun exposure. It will also react with a certain amount of ground, and will remain on the ground for a long time. There were also related reports on TV a few years ago. The guiding stars drawn on the ground over time were long and difficult to preserve, so later molds of this shape were created for ease of use, and when used, they were directly embedded in the soil and then flattened by horse-drawn carts. This also avoids the disappearance of the pattern.

After the old cat finished speaking, Lin Xihui acted the same as the old cat before, lying on the ground and sniffing, and then said, "This star may have existed for a hundred years, and it should be used as an indication of the characteristics." ”

As soon as Lin Xihui's voice fell, the old cat had already walked alone in the direction indicated by the star, and the four of us immediately followed. According to the instructions of the star, about every forty or fifty meters, you will meet the direction indicated by the next star. After seven stars, a strange scene happened.

I saw that near the star in front of me, next to the bushes, there was a star, which was the opposite direction of this star and the star in front of us!

There were two stars in completely opposite directions. The bald head jokingly said, "Fuck, this is when you carve stars, what's wrong with carving a defective product?" Why do you need to carve another one? It's not good to carve, you have to be naughty to carve in the opposite direction. ”

Lin Xihui asked the old cat, how should we go now?

The old cat shook his head, saying that he could only follow the instructions of the star here, and he didn't know where to go now. Lin Yuhui frowned and looked at the old cat, and asked suspiciously, "You don't know the way?" ”

The old cat replied calmly, "It's also my first time here." ”

The old cat's words surprised several of us, because from the previous experience in the broken faucet, the old cat at least understands the route here, and cannot and cannot find the door. But looking at it now, if he really knew the way, he wouldn't have relied on this so-called star. These two points are too contradictory.

It is surrounded by dense metasequoia forests, and it is easy to get lost in this place without a map. When we walked all the way, the old cat every few tens of meters, will make a mark on the metasequoia tree, the purpose is also very clear, is to prevent us from getting lost, from this point of view, the old cat really doesn't seem to know here, but we are in the broken dragon platform, he accurately found the so-called "Shengmen", and took us to escape from the Shengmen What is going on?

Lin Xihui walked to the side of the two stars respectively, as before, lying on the ground and sniffing, and then her expression became serious, she pointed to the star on the left hand side and said to us, this star should have existed for a longer time than the other one, but the other star has existed for more than a hundred years, she speculated that the star on the left hand may be a thousand years ago, otherwise she would not be able to make this distinction between the stars.

I asked Lin Xihui curiously, how did she judge the time and age of the star?

She didn't shy away from it, and explained to me with a slight smile that it was actually very simple, it was to rely on the smell of the soil. As soon as Lin Xihui's words fell, the bald head cast a surprised gaze, and the bald head said, "Woman, could it be that you have inherited the stunt "Qi Exploration" of the old ghost Li from the north? ”

Lin Xihui shrugged her shoulders and said nothing, neither admitting nor denying it, she looked at the old cat who was lying on the ground studying the star.

So I asked the bald head, what is "probe"? The bald head explained to me that according to legend, the northern "glimpse of the child" Li Lao Ghost has a stunt that is to detect the qi, and it is said that he can perceive the "breath" of all things. As we all know, in Feng Shui, everything has "qi", people have popularity, heaven has weather, earth has earth qi, etc., if you can find the source of "qi", you can perceive all things.

The bald head said that the root of this qi detection stunt may be traced back to ancient times, when the Emperor Qi Tianren was said to grasp all things according to "qi". Zhang Tian, a famous captain in the Eastern Han Dynasty, was a master of "probing qi", Zhang Tian robbed the tomb, never looked at the map, as long as he grabbed a handful of soil, put it on the tip of his nose and sniffed it, he knew whether there was an ancient tomb there, how long the ancient tomb existed, and even the scope of the ancient tomb could know a little bit about it. In the chamber of the tomb, sniff the tomb wall or stone bricks to know if there is a mechanism. Therefore, Zhang Tian has always been able to escape from the tomb robbery. He also had a nickname called "Ghost General".

Before the bald head finished speaking, Lin Xihui interrupted him, saying that he was not exaggerating, she was just judging based on the taste of the soil, and there was no magical "probing". She didn't seem to have the slightest connection to the tomb robbing business that the bald head was talking about.

In fact, there is no need to be bald to doubt it, I myself am very confused, what is the origin of this Lin Xihui? Since she appeared in the research laboratory with Professor Chen, she must also have something to do with the disease control and biochemistry team, or more popularly, she is an important member of a certain bureau. But from our experience, it seems that this little girl is not only skilled, but also has a wide understanding of Feng Shui, and does not look like an ordinary state official at all.

I could hear it, let the bald head continue, and asked if the bald head's "glancing at the handle" and "touching the gold captain" were not a profession? This bald head is also a big poor mouth, he can't stop talking, and he can't walk for the time being, so the bald head simply sat cross-legged on the ground, and said to me with flying eyebrows, "The look is the "head" of the thief, and it is not the same thing as touching the gold captain, this is a very ancient and mysterious profession......"
