With Wang Ziming's explanation, Bai Yun flew to look at the strange fireflies around, because the cave where the fireflies inhabited was as bright as day, so there was no light problem, and all the subtle things could be seen clearly.

Those glowing fireflies are dragging translucent crystal filaments of different lengths under their abdomen, and each crystal filament seems to condense a layer of "water droplets", like a crystal bead curtain.

Wang Ziming said that these firefly larvae can not only glow, but also secrete filaments with water-like mucus, and these dazzling fluorescent crystal beads are the "bait" and "fishing line" that hide the killing machine, luring those insects that can be preyed on by them to throw nets from themselves, and they will be stuck when they touch the crystal filament.

Firefly larvae crawl over for a meal, and this predation is very similar to that of spiders, with the only difference being that spiders do not emit light.

These fireflies have a lifespan of one year, glow and spin when they are young, and become adults in six to nine months, and the fluorescence becomes brighter with age.

However, after the adult worm evolved, it sadly lost its mouth, could not eat, and although it had wings, it lost its function and could not fly.

They can only frantically mate* and lay eggs, in a vain attempt to prolong their lives in another way, until they are exhausted.

After two or three days, the adults will use their last strength to crash into the silk nets of the larvae, and sacrifice themselves for food for their offspring.

Hearing Wang Ziming say this, Bai Yunfei was also amazed by this beautiful insect in his heart.

After not going far, the ground was no longer rocky, but a flat, very large area appeared.

It seems that it is a silted mud pond, probably formed by the accumulation of a lake here, or by the erosion and siltation of surface water or underground rivers, and then there is no water source, and dry land is formed here.

While walking here, Lu Wuyang introduced to Bai Yunfei the process of their previous exploration of the road, and it happened that everyone also walked to the hole that appeared when they fell to the people.

Bai Yunfei squatted in front of the hole, shining a flashlight on the unfathomable interior of its black hole, and fell into deep thought for a moment.

It turned out that the flat mud pond formed by siltation was not solid underneath.

Rather, when the mud pond was formed, there may have been a large amount of air, or animals and plants left in it, and later due to decay and other reasons, there were countless deep and large cavities underneath.

And because at the time of the formation of the trap, for some special reasons, such as the anonymous design, through artificial means to retain air, or to inject something that accelerates the decay of animals and plants, and then wash and silt up with water or artificial water to create a new layer of mud.

In this way, the trap that gradually formed below was covered, and it became a geological structure like a lake bed and a mud pond, but the bottom was a trap that people could not avoid if they fell into it.

Bai Yunfei asked them if they hadn't tried to get past the stone wall on the side of the mud pond.

Because Bai Yunfei saw that although the mud pond was wide, it was not impossible to see at a glance, and the places where the fireflies inhabited on the stone walls on both sides were not all stone walls?

Cao Longxuan said that everyone can naturally think of this, but it is absolutely impossible.

Because I think that the anonymous design tomb is extremely vicious, everyone has seen it as early as in the Mogao Grottoes in Dunhuang.

Originally, everyone wanted to use climbing spikes and climbing locks to pass from the side, but just as they tried it, the fireflies were frightened and flew out of their nests and flew into the air.

And as soon as these fireflies leave the nest, the ugly, terrifying blood-red bugs will immediately appear.

And there are not just one, but as many as five or six.

Cao Longxuan asserted that if all the fireflies in the area were to be scattered away from their nests, it would attract more "death bugs".

When they withdrew and the fireflies returned to their nests, the terrifying "death bugs" reluctantly left and disappeared.

There must have been a special arrangement in this firefly cave, so that the "death bugs" who eat fireflies do not dare to approach their nests, but once they leave the nests, the "death bugs" will track them down.

Think about it, that's how people are in the oil pool.

Niu Gang searched for a passage at the bottom of the pool, disturbing the tranquility in the oil, and the black bugs came up, thus attracting the fireflies, and then the "death bugs".

It can be seen that the designs of this anonymous are really interlocking and interconnected.

If everyone ventures to force their way through from the side, it seems that the anonymous clan has its own insidious plan waiting for everyone.

At that time, it is estimated that it will touch a certain mechanism again, and black oil may flow out of nowhere.

It will also be discharged by that strange worm, igniting black oil.

Below was a mud pond full of traps, which was even more dangerous than the oil pool.

At least if you fall into the oil pool, you can find a way to live, and if you fall under this mud pond, you should not be able to live.

Bai Yunfei listened to him and thought about it carefully, it was really like this, this hateful eunuch!

"For now," Cao Longxuan looked around, took a long breath, and sighed, "It seems that there is only one way to go all the way beyond this mud pond." Come to think of it, when the anonymous man designed it, it was to force the tomb robbers to go this way. ”

"Aren't they going to die here?" Han Debang's eyes widened and he asked in disbelief.

"It's not like that, there are a few stone plates there, aren't people not making full use of them, I think, maybe this thing is the solution, and I don't know."

Following Cao Longxuan's fingers, everyone saw that on the stone slope above the mud pond on the right, there were several black and bright stone plates.

It would be inaccurate to say that they are stone plates, but they are actually large, thick stones, but they are not spherical, but flattened discs, each about two meters in diameter.

Cao Longxuan said as he walked towards the stone plates, and everyone followed behind him.

Listening to what they discussed, it must have been during the time that Bai Yunfei was in a coma, and they had already searched around here, so they were no strangers to these stone plates.

In the exposed hole by the mud pond just now, it was obvious that someone accidentally stepped on it when they were investigating, but fortunately, there were many people at that time, and the response was timely, and they were rescued alive.

After Bai Yunfei inquired about Li Yulan beside him, it was really his guess that Lu Wuyang fell in at that time, but fortunately, there was no danger.

Moreover, she also said that this vast firefly cave is large, but other places have been searched several times, and not only have they found nothing, but there are no such things as these stone plates.

If the clues found in the current investigation are abnormal and valuable, then there are only these stone plates left.

Her words made Bai Yunfei more and more recognize Cao Longxuan's judgment just now.

The distance was not far, and it didn't take long for everyone to walk to these stone plates.

These stone disks are black and oily, basically disc-shaped, and there are five in total.

Each is about two meters in diameter, and the height is about half a meter in thickness.

Bai Yunfei carefully touched it with his hand for a long time, and finally concluded that this was the same rock as the oil shale with extremely rich oil content used in the "torture balance" in the anonymous tomb in the Mogao Grottoes in Dunhuang.

This kind of oil shale has a huge oil content, and the oil slick on the surface is scraped off with an iron tool, and a new layer of oil film will slowly seep out over time.

The stone plate is not completely flat, especially the side that touches the ground, and like the vegetable plate used in the kitchen at home, it is a curved surface, with some upward tilt.

The same is true for the top and bottom, but the arc is downward, so from the overall shape, it looks like a Go piece that has been expanded a hundred times.

In this starry sky of fireflies, what are these stone plates for?

If it is said that it is not artificially placed, but naturally formed, no one will believe it.

Although there are no traces of manual chiseling on these five stone plates, these traces can be eliminated by polishing during the chisel, not to mention that thousands of years have passed, and even at that time, there may not be any traces of chiseling.

Bai Yunfei raised this question, but everyone did not answer, and after a while, Wang Ziming, who has always been taciturn, said:

"Didn't Mr. Cao say just now, the designer of the tomb forced us to cross this mud pond, so I put these stone plates, it's as simple as that."

"But how can you be sure that these stone plates are used to cross this mud pond?" Li Yulan asked puzzled.

Wang Ziming spread his hands: "I'm not sure, it's pure speculation." But..."

"But what?" Cao Longxuan asked.

Everyone also looked at him, and no one interrupted his train of thought.

"However, all the instruments of the world are for my use.

It doesn't matter what it's for, whether it's a bait or a key to unlock the problem, even if it's just the waste left over from the construction of the underground palace, as long as everyone can use it, use it.

If you don't need it, just ignore it, it's as simple as that. ”

Wang Ziming patted one of the stone plates and said lightly.

"What's the use?" Niu Gang is the most reluctant person to use his brain, so when something happens, he must ask others, and it is sometimes more difficult for him to use his brain than to kill him.

Wang Ziming shook his head, indicating that this was not clear.

Lu Wuyang has always had a hobby of studying all kinds of things, at this time everyone stood around a few stone plates, when discussing the real use of these stone plates, Lu Wuyang was already lying on the ground, looking at this for a while, touching that for a while, and studying these stone plates for a long time.

Bai Yunfei asked him if he had found anything on these stone plates.

He said he didn't find anything, and then went back to research.

Anyway, now everyone has no landing, no sense of direction at all, he can study as much as he likes, so everyone ignores him.

Later, because everyone had no clue for a long time, they all sat on these stone plates to rest, and Lu Wuyang studied about the same, so he also sat down to rest.

Old Ghost Su made fun of him: "Hey, you baby, what are you studying?" Can you install two wings and carry us over? ”

Lu Wuyang patted the dirt on his hands and said, "Don't think about it if you want to fly, but you always want to get a free ticket, I can make you a few ships." ”

"What do you mean, you mean that these stones can be used as boats?" Old Ghost Su asked.

"Of course." Lu Wuyang replied.

"What's the point?" Old Ghost Su was a little disdainful and pursed his lips.

"Everyone sits on the top and drifts across the ocean." Lu Wuyang actually said this sentence like a story.

Old Ghost Su rolled his eyes:

"Your baby, you have to know that we are the 'Eight Immortals of the Earth', but we are not the real Eight Immortals, and we are still drifting over?! How to drift?

If we really have that ability, just blow a breath of fairy breath, and we can blow this stone into gold, and then everyone will get rich and make a big ball, which is simply a little stone into gold.

Do you still need to drill holes like a mouse, do this dad doesn't love to do things? ”

Lu Wuyang said: "In Death Valley National Park in California, there is a strange phenomenon:

The park has a dry lake with a very flat bed that stretches about 2.5 miles from north to south.

The fact that hundreds of pounds of stones can glide on the lakebed here is not a man-made hype, but a real natural phenomenon.

This phenomenon has plagued scientists for many years, with various speculations and theories, such as the blowing of strong winds after rain, which can cause heavy rocks to slide on the smooth lake bed.

These rocks, which are considered 'sail stones', are just lying on the 'basin track' and seem to be sliding every day during the race.

Some scientists have suggested that it may be related to mysterious factors such as alien 'UFO' activities.

But a NASA guy named Ralph... Ah, a scientist named Ralph Lorenz has discovered that in winter conditions, there is enough water and ice to keep rocks floating along the muddy bottom of the 'basin runway' and leaving traces as the rocks move so that people can clearly see that they are gliding. ”
