The four of them were walking in the valley with one foot deep and one foot shallow. Li Lvyan couldn't help but ask, "Why is this place different from the previous underground fortress? It's completely out of touch?"
Jing Qiongshuang said, "It's very simple, because this place was originally a huge group of underground tombs, but it was modified by a group of latecomers, and even they could only change part of the structure, and they could not completely change the world."
.”
"You mean those things can't catch up for the time being? Are we completely out of there?"
It’s a lie to say you’re unhappy, who likes danger?
"That's right, but don't get too complacent. There are things more terrifying than walking corpses waiting for you here. The safety you thought was only temporary."
Before she could say anything happy, Black Glasses poured a basin of cold water down to extinguish the spark. And it was obvious that everything Jing Qiongshuang learned was also told to her by Black Glasses, and she must have driven the car while she was dreaming.
The "secret meeting" that Wo Gua mentioned was that there was something that could only be told to Jing Qiongshuang but not to himself? I had been through life and death with him so many times.
Also, what is "that thing" mentioned by Black Glasses? Is there anything more terrifying than tens of thousands of zombies here?
"By the way, Dung Beetle, you said before that you knew how the old immortal controlled the walking corpses, but you didn't say, what was that?" Wo Gua asked curiously.
"It's very simple -" Li Lvyan whispered back, as if he was annoyed by his slowness, "it's the radio wave." In fact, he should have thought of it earlier, but the situation was always complicated and changeable, and he was not allowed to
Think more.
The four of them followed the rugged road and followed the guidance of the black glasses, picking their way through the rugged rocky depressions. After about five minutes, they stopped in front of a faint cave entrance. Li Green Ant looked around curiously.
The height of the gravel in the ten o'clock direction is five meters, and the scattered area is 18.9 square meters. The gravel shot out concentratedly in the four o'clock and five o'clock directions has a cloth-like interface...
At this time, the data in Li Lvyan's mind was running at a high speed, and a transparent mind map suddenly appeared, and behind the mind map was a three-dimensional scene, which could restore everything that had happened here to the greatest extent possible.
In the scene, several people in camouflage uniforms were holding detonators in their hands, and others were measuring the length of the fuse. This place was originally a closed mountain, which completely separated the entrance of the cave. I don’t know how they determined it until—
—
Until black glasses appeared in that scene. He was holding what seemed to be a tablet analyzer in his hand. He looked at the analyzer, then looked around, and finally confirmed with everyone the explosives and detonators that needed to be used.
Place.
Is it a bulk 0.5 mm thick grain column, or a hot wire detonation, emmmmm... In order to avoid the shortcoming of the very small diameter of ordinary detonators, we also chose to thicken the grain size, because the average detonation velocity of general detonators is 1500m·s-
1. If it is a pressure-loaded charge column and impact ignition, the detonation velocity can reach 1700m·s-1, while the detonation speed of a charge column with a diameter of 0.3~0.4mm and a height of 1cm is about 1500m·s-1. When the crystal particle size is 50~200μm
The stable detonation velocity is generally 1 880 ~ 2400 m·s-1. However, with a thickened grain size, it can still detonate when the diameter is 25m. When the diameter is reduced to about 10m, the maximum combustion velocity is about 7m·s-1.
Li Lvyan tilted his head and looked at the black glasses, "Is it silver azide?"
Even though she knew about Li Lvyan's excellence, Jing Qiongshuang was still surprised. From a professional point of view, she could certainly tell that blasting operations had been carried out here, but he had never been at the scene, so how could he know the details of the operations at that time?
What exactly are explosives?
She glanced at Black Glasses a little unsurely, and Black Glasses nodded slightly, confirming Li Lvyan's guess. Jing Qiongshuang took a breath: It's true.
Black Glasses was not that surprised. After all, Li Lvyan's full strength had not yet been fully demonstrated. This was just the tip of the iceberg. In the original Snow Leopard Commando, Li Gaifeng, who had a mind comparable to a supercomputer, was Li Lvyan.
His father is a character who can make even the commander-in-chief tremble.
In fact, Li Green Ant guessed it very easily. The detonation velocity of silver azide reaches 3830m·s-1 when the density is 2g·cm-3, and the detonation velocity at the maximum density is 4400m·s-1. And the detonation velocity of azide
The charging density of silver explosion speed is 2g·cm-3. In this case, the charging pressure of the detonator is equal to 40 Pascal × 102 (MPa). At this time, the detonation efficiency is very high compared to that of the detonator, even several times higher than that of the detonator.
Lead azide will naturally become the first choice.
It's just that Li Lvyan has some academic doubts. According to the situation caused by the explosion, the effect is very good, but according to the results, when they chose to use silver azide, they did not overcome its biggest shortcomings.
, that is, a certain crystal form of silver azide with extremely high friction sensitivity limits its application. Although at the beginning of the configuration, a concentrated silver nitrate solution and sodium azide can be mixed in a certain proportion to form a colloidal azide.
silver azide polymer, but this form of silver azide is less sensitive than crystals in solution.
Another way to reduce the sensitivity of silver azide is to add an inert absorbent to the silver azide solution. In this method, the inert material separates the crystal molecules from each other. However, in the silver azide precipitation, it will also
The presence of other substances, such as cyanamide ions, will accelerate the decomposition rate and reduce the explosion temperature.
How did they overcome this technical difficulty?
Just as Li Lvyan was about to ask, Black Glasses waved to the three of them and stopped staying.
He quickly entered the space exploded by the explosive.
It wasn't until he came to this space that Li Lvyan finally saw the ruins of Loulan for the first time in the bottomless Lop Nur underground. It was not a military fortress that had been transformed by someone, nor was it a future.
The developed wilderness is the ruins of Loulan in the true sense!
The excitement is beyond words.
The space unfolds like a round table. The entire space is no longer boxy as before. There is a stone sutra block approximately every quarter of a circle. There are some murals carved around the stone wall. The color has peeled off due to age.
It has lost its original splendor and beauty, but those murals such as fighting beasts, thousands of flowers, worship, and processions must have been swaying and colorful when they were first carved.
The roof is paved with glazed tiles. At first glance, it looks like a colorful and transparent kaleidoscope. However, the reason why the four people came in for so long, but the place is brightly lit, is because the glazed tiles on the roof seem to contain a unique liquid, which not only can be used in the dark
It is shining brightly, like a firefly. Although the light is dim, it can still bloom after a thousand years.
It's amazing.
This unique and exquisite structure is the first time Li Green Ant has seen it, and has even never heard of it.
As we all know, in human knowledge, in addition to the sun itself that can emit light, many other things need the sun to reflect light. Generally, things that can emit light by themselves have their own shelf life, such as fireflies, candles, etc.
Lighting a lamp, such as a lover's eyes... Even if these things emit light, they still need to go through another process, and precisely because there is no perpetual motion machine in the world, things that can emit light by themselves are even more precious.
But here, in this ancient Loulan, which has almost disappeared from the historical stage for thousands of years, there are actually things that can shine by themselves and have been preserved for thousands of years - it cannot but be shocking.
However, Li Green Ant will soon discover that these lights are not to guide intruders, but to——
Before he could recover, a sarcophagus originally placed in the center of the room was inadvertently ignored. When Wogua realized that he wanted to open it, Black Glasses just said lightly: "It has been opened, and it is empty inside.
"
Oh ho——
The energy that Wo Gua had just cheered up was gone again. After all, he hoped that there was some treasure in it that could help him make a fortune.
Li Green Ant found that the hole that was blown up happened to be at the entrance of the tomb. He looked at the entrance, but the entrance was a bit strange: there were thousands of pounds of stones at the entrance of each tomb to stop tomb robbers and give them something to do.
It is normal to never come back, but the thousand-jin stone in this tomb seems to have been destroyed by someone, but it found a way to make it fall.
Of course, this was not because he was having trouble with himself, but Li Lvyan guessed that there might be a group of people who had encountered something before, and even though they knew full well that they could not escape, they still chose to do so resolutely.
The question is, what danger is more terrifying than being trapped to death here?
What's even more strange is that if it is really what I think, then the bodies of those people should be in this room, but they are missing here?
Black Glasses said that they entered by force, which means that before they opened the cave, it must have been intact. Such a thick stone must be difficult to achieve without silver azide. Where did those people go?
Woolen cloth?
Is there another exit from this place?
Black Glasses slowly walked behind Li Lvyan. Li Lvyan was deep in thought and didn't hear any movement. When he felt someone standing behind him, he was startled to find that it was Black Glasses.
"Why are you here?"
"You can see it, right?" Black Glasses seemed to have some certainty, "There must be another exit from this place."
No wonder Black Glasses didn't want to leave immediately, but came here. It turned out that it was for another exit. Li Lvyan touched his head, a little awkward, "To be honest, I guess there is a second exit, but I don't have anything."
I don’t have a clue, so I haven’t figured out where it is yet.”
The face of Black Glasses changed slightly, and his tone suddenly sounded a little urgent: "You must find another exit here. I took you here to take great risks. If time goes by, those things will soon be destroyed."
Come out!!"
Those - things??
Li Lvyan had never seen the look of Black Glasses before, and he was a little bit murmuring in his heart: Why did Black Glasses look different from before? Whether it was movements or expressions. But thinking that Black Glasses was so seriously injured, maybe it was
The sequelae left after the injury were not guaranteed, so I could only reluctantly say, "I'll try my best."
"It's not about trying your best, it's about doing it for sure!"
For a moment, Jing Qiongshuang, Wo Gua and Li Lvyan all looked at Black Glasses curiously. Black Glasses seemed to realize that his tone was a bit too aggressive. He took a deep breath and glanced at the exit, seeming a little worried.
.
Strange, since Black Glasses also said that this place is isolated from the military fortress, the danger of the walking corpses is not enough. Is there anything more dangerous than the walking corpses?
However, Li Green Ant soon saw this terrifying existence.
The problem now is that both Black Glasses and himself are certain, thinking that there will be a second exit here. In this case, they need to find it. Li Green Ant's instinct is to open the sarcophagus, but at this time Black Glasses behaves strangely
appears again.
"There is nothing inside, so the coffin cannot be opened."
??
Wo Gua tentatively said, "Boss, I won't open the coffin."
How do you make sure there’s nothing inside?”
"I've already seen it."
"But boss, there are all walls here. The only thing that has some problems and can't be seen is the inside of the coffin. Don't you want the dung beetle to find the exit?"
Black Glasses calmly said, "I told you, you can't open the coffin."
For a moment, the atmosphere was so strange and wrong that even Jing Qiongshuang could smell it. She frowned slightly: There was indeed something wrong with the team leader.
As time passed by, Li Lvyan looked up and down, left and right, front and back, inside and out. Except for the mysterious coffin, he looked at the rest.
When I said it, I didn't even see a cockroach, and I couldn't help but start to doubt my own thoughts: Could it be that I had guessed wrong?
"呲呲——"
It was as if dozens of vipers were spitting out snake bites at the same time, which suddenly made everyone's nerves tense. The black glasses made a "teng" sound and were on high alert, and said in a low voice, "No, they are still coming."
they?
Black glasses know??
Do you know they will definitely come to this place?
What Li Lvyan always felt was that something was wrong. Even though he had just turned around and knocked all the floor tiles with his knuckles, he still couldn't find the way. However, in some places, he could clearly see bullet holes and
The traces of fighting were very new, not even completely covered by dust, no more than a month old.
Are they black glasses?
With Black Glasses' ability, these strange things will be discovered by him immediately, unless these traces are their own doing, but since it was Black Glasses' doing, why didn't he take the initiative to speak out?
What’s even stranger is——
Li Lvyan once again looked at the tightly covered sarcophagus - what is the purpose and reason of the black glasses, and they still refuse to let us see what is inside?
When Wo Gua heard the sound of "Bah", he got goosebumps all over his body, as if he had to urinate and defecate at the same time but couldn't find the toilet. The goosebumps also made his hair stand on end and he felt awkward. He turned around and masturbated.
He rolled up his arms, but at that moment he heard an urgent shout.
"Wogua! Be careful!!"
"Qiang——咻——"
A sharp silver thread was like a puff of smoke, flying out of Wo Gua's neck, spinning around and nailing it to the wall parallel to Wo Gua's eyes.
Wo Gua was immediately furious, "I said, big sister, you——"
The world has survived matter and antimatter, going through the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian periods of the Paleozoic era, and then reaching the Triassic, Jurassic and Cretaceous periods of the Mesozoic era.
, and then the Tertiary and Quaternary periods of the Cenozoic. In the strata of different periods, most of the standard fossils of ancient animals and plants are preserved. There is a certain order in the sooner or later the fossils of various animals and plants appear. The lower the
The earlier one appears, the higher the level, the later one appears.
The absolute age is based on measuring the content of a certain radioactive element and its metamorphosis products in the rock to calculate the actual number of years since the rock was formed. The older the rock, the longer the strata are. Each unit of geological time
It should be how many years ago it started and how many years ago it ended, so that you can calculate how many years it lasted in total.
In these years, the single-celled animals that crawled ashore from paramecium continued to evolve. Some animals survived tenaciously on the earth. From ancient times to the present, their bloodlines have been quite intact and have not changed much. The most typical example
, which is the chordate Komodo dragon, also known as Komodo dragon and magic dragon.
This group is the largest lizard known to exist today. Komodo dragons are ferocious. Adults eat the young of the same species and sometimes eat other adults. They can move quickly and attack humans; but they mainly feed on carrion and come out of their holes every day.
It forages thousands of meters away. The largest accurately measured specimen in its family is a male gifted to an American zoologist by Bima Sultan in 1928. In 1937, it was briefly exhibited at the St. Louis Zoo in Missouri, USA.
It is 3.10 meters long and weighs 166 kilograms.
Wo Gua turned around and saw a pus-filled black lizard about one meter long and about the width of a bucket. It was spitting out snakes and lying on one of the stone sutra pillars, just a stone's throw away from Wo Gua.
From a distance, he opened his scarlet eyes eagerly, staring at this delicacy.
The whole body of that thing was pitch black, and its surface was covered with scales as fine and evenly distributed as vipers. However, most of the scales were raised high by pustules of unknown disease under the skin, making them pitted and a bit like a fisherman's net.
It is pitch black, its claws are similar to those of a turtle, with pointed barbs, and its head is more like a cobra in the desert, shaped like an inverted triangle, showing a cunning and greedy appearance.
Just when Wogua was dumbfounded, many creatures that were exactly the same as this thing crawled in one after another from the big hole that was blasted before. There were at least a dozen of them. Are there any more outside? I don't know.
"Damn it, what the hell is this??"
The group of pustule lizards in front of me were moving extremely fast, but their brains seemed a bit awkward, because the knife Jing Qiongshuang threw at the critical moment of Wogua had clearly cut off the scalp of the pustule lizards.
It was a piece, but the pustule lizard still looked at the nest of melon with eager eyes, as if it would never leave until it had eaten the nest of melon.
Wo Gua was so frightened that his legs trembled, and he almost wanted to leave first, but the scarlet and vicious eyes of the pustule lizard, coupled with the "squeaking" of snakes, made Wo Gua's legs weak, and even Jing Qiong Shuang almost missed it just now
