The polar night had fallen, and although it was about ten o'clock in the morning, the sky was still pitch black.

Fortunately, there are GPS coordinates, and Shangguan Qing only needs to fly according to the coordinates.

"Are you sure there is no one on the construction site anymore?" asked Li Huan, staring at Fiona.

Everyone was wearing cold clothing, but Fiona, who had only thin clothes. Vampires don't have a body temperature in the first place, and the cold is not a problem for her at all, but she is better than everyone else at this point. However, Li Huan is not worried about her backwater, with the blood of the origin in her hands, as long as she dares to turn against the water, it will be the end of ashes.

In fact, Fiona didn't intend to turn back, and replied honestly: "Master, there was no one at the construction site when I left, and at most there were some blood slaves wandering, but they went under my control, and they are almost ice sculptures now." ”

The noise of the helicopter was very loud, and everyone was not wearing headphones, but everyone had cultivated themselves, and in such a small space, they could communicate with their mental power, so there was no problem at all. According to the coordinate point, Shangguan Qing soon controlled the helicopter to fly to its location, and after the small helicopter hovered in mid-air, she fired a flare downward.

Among the arms brought by Ash, there are also a lot of individual equipment, since what is to be found is Nazi doomsday technology, then arms are indispensable.

The green flares are very penetrating, and there is a white world below, which is very reflective, and a single flare can illuminate a radius of several kilometers. Underneath the helicopter, there are several icebergs with a height of more than 200 meters, the terrain is rugged, and in the polar night, the flares are reflected, emitting a green light, like a dream world.

These icebergs look ordinary, and among the many icebergs, there is a small plain, about the size of five or six main courses, and it is estimated that this was once a glacial lake, which was completely covered in ice.

"It's down there. Fiona affirmed.

"Okay, let's go down. Li Huan nodded.

Shangguan Qing controlled the helicopter sideways, landed on the ice field, and docked under an iceberg. The huge noise of the helicopter startled a few things, Li Huan looked carefully, it was the arctic fox who was trying to find food when the polar night had just fallen and the temperature had not yet reached its worst. At this time, the fur on the Arctic fox had not completely turned white, and the wind brought up by the helicopter rotor made several Arctic foxes crawl one after another. When they were on their feet, they bared their teeth at the helicopter and ran away.

Animals are more alert than people, but if anyone is working here, the animals will definitely not come close.

If there is an arctic fox, it means that there is no one here, Li Huan and the four of them got off the helicopter, counted the equipment, and under the leadership of Fiona, headed towards one of the peaks.

Li Huan walked in front with a lighting stick, and this place was simply a magical world. The red light of the lighting rod reflects a transparent iceberg, and the light reflects the entire iceberg in red. The iceberg is covered in a thin layer of snow and some of the most tenacious vegetation in the world, and from under the snow and vegetation shines through, everything is a warm red color that looks like a dream.

It is a very old iceberg that has lost its edges and corners due to glacial dissolution and weathering. The slope between the icebergs is also very gentle. Li Huan always thought that the Arctic was a frozen world, but along the way, he could still see a lot of frozen humus and plants growing on the humus.

"It's all ice, it's so beautiful. How can plants grow on the ice?" Shangguan Qing sighed: "I haven't come to the North Pole, I really don't believe that there is such a strange beauty in the world." ”

"Hehe, you don't know this, in fact, there are many higher plants in the polar regions, although the ground is a permanent frozen layer, but the first lichen plants grow and decay, and slowly accumulate into a humus layer, the stems and leaves of these plants are tightly attached to the ground, can withstand the pressure of snow well. As long as there is a short period of warm weather each year, the plant will sprout immediately, and the process of growth, flowering, and fruiting will be completed in a short time. There are many valuable plants in the polar regions, such as horseradish for scurvy, the fruit of the swamp black rice tree for consumption, and plants of the grass family and sedge family for animal consumption. Li Huan said.

"You know this!" Shangguan Qing was slightly startled.

"You forgot what I came from, if I hadn't been brought to Panshi Island by Chen Lao, I might have come to the North Pole for live broadcast. Li Huan laughed.

Shangguan Qing not only sighed, but also remembered the scene of the first meeting with Li Huan. At that time, Li Huan was still a little immature, but now, he has grown into a man who stands up to the sky.

The group of four followed the iceberg upwards and quickly approached the mountain that Fiona was referring to.

The iceberg is not steep, on the contrary, it is very gentle. However, the mountain is thick, and there are many lichen plants growing on the mountain, rendering the whole mountain dark brown, and it looks vibrant, very beautiful. On lichen plants, there are brightly colored berries, red, purple, yellow, all over the place.

This is the magic of nature.

Even in the harshest part of the Arctic Circle, the place full of life is ridiculed.

Although everything here was very beautiful, Li Huan set his eyes on a few huge pieces of ice.

On a small gentle slope halfway up the mountain, Li Huan found some ice cubes in a circle, which had been frozen in the Arctic for an unknown number of years, and even looked like they had turned dim yellow. The largest piece of ice was the size of a living room, and even the smallest weighed tens of tons by sight. Several pieces of solid ice are clustered together to form a ring.

From the perspective of ordinary people, these huge pieces of ice are nothing special, but in Li Huan's eyes, these pieces of ice are dazzling.

First of all, this is a very old iceberg, under the action of glacial dissolution and weathering, except for the ice that cracks and falls from the iceberg itself, it can still maintain a certain edges and corners, and the other iceberg itself or other positions, no edges and corners can be seen at all. And the huge pieces of ice in front of me, although they are not angular, are absolutely incompatible with everything. Obviously, this huge ice has not been around for long, and the snow, sunshine and blizzard have not yet polished it.

Secondly, the location of these ice blocks is very strange, if you want to say that they fall off the mountain naturally, then according to the friction of the ice surface, the fallen hard ice can roll a kilometer away, even if it does not roll a kilometer away, it is absolutely impossible to stay halfway up the mountain.

Obviously, the ice is not falling off naturally, but man-made.

Seeing that Li Huan's gaze stayed on the solid ice, Fiona took the initiative to stand up and said, "The master's gaze is like a torch, and that place is the previous construction site. But like I said, there was no one anymore, and when it came to the polar night, all the work stopped. ”

"Well, let's go check it out. Li Huan said: "Shangguan, Xiwei, you are on guard around, if you see anything that moves, don't hesitate to shoot immediately, understand?"

"Go ahead, I'm here for you to rest assured. Shangguan Qing patted the assault rifle in his hand.

In the bitter cold of the Arctic, even Sivir carried a gun and, of course, her bow and arrows, but only then in the most dangerous battles. The two of them immediately formed a defensive formation around them that could look after each other, and watched vigilantly outside the circle.

The area around the ring of ice, about the size of a football field. After Li Huan walked into the ice circle, he found that this place was very different from the outside. Within the ice circle, there are almost no traces of plants, and the ground is full of broken ice, and it is obvious that people have touched this place. Li Huan groaned for a moment and kicked away a piece of snow, of course, he saw traces of man-made fibers under the snow.

This is probably a tent on the construction site in the dark sun, but without the protection of the Thunder Dao people, and Fiona came to make trouble, and after a few snowstorms, the entire construction site was crushed under the snow.

"Why did Dark Sun invite the engineering team to come? Can't you do it yourself?" Li Huan pulled up a tent stand from the ground and looked at it, it was indeed crushed by the snow.

"Master, you don't know, this place is so strange that no spell can work. The few pieces of ice you see were cut down by the Lei Dao people from the nearby mountains with the lightning method, but in this circle, he led the lightning down but it had no effect at all, and he didn't even break through a layer of ice skin. On the contrary, ordinary machinery has a role, so the engineering team was invited in desperation. Otherwise, how could this kind of thing involve ordinary people. Fiona explained.

"In other words, there is something here that inhibits your power?" Li Huan muttered.

"Yes master, so to speak...... I'll show you. After Fiona finished speaking, the bright red cherry mouth said silently, and with a finger, a green electric light hit the ice that Li Huan kicked away. When the green electric light disappeared, sure enough, there was not even a small crater in the ice. Fiona explained, "This is our corrosion, my corrosion technique can melt even steel, but it doesn't work here. ”

After saying that, she added: "It's not just that my corrosion technique doesn't work, but I've tried at least a hundred spells on this ice, but none of them are useful......"

Li Huan nodded thoughtfully, and stepped on the ice with his foot: "Take me to the excavation site." ”

Fiona led Li Huan around the ice circle several times, and finally stood in one place, she first said respectfully: "Please master unfold some, Fiona wants to clear the floating snow." ”

Li Huan took a few steps back.

I saw that Fiona's originally green pupils suddenly turned bright red, and under the slight tremor of her body, two huge bat wings unfolded. She flapped her bat's wings and brought a strong air current, blowing away all the snow in a nearby area. Soon, under the cleaning of Fiona's bat's wings, a cave about ten meters in diameter and five meters deep was revealed under a cloud of snow, facing down at forty-five degrees.

Seeing this cave, Fiona's expression was happy: "Master, this is it! ”

With that, Fiona walked into the cave and flapped her wings to create a huge wave of air. The snowflakes that had poured into the cave in the previous blizzards suddenly stirred up and rushed out of the cave entrance to a height of tens of meters. This process lasted about a few minutes, and Fiona came out of the cave with a look of remorse: "The master's previous snowstorms have scrapped half of the project...... I only cleared out about forty meters or so to a depth of about forty meters. Now that we don't have an engineering team and no machines, what should we do? According to the records, the approximate location of what we are looking for should be about 200 meters underground. ”

In the case that all the spells did not work, there was still a distance of about one hundred and fifty meters, and Li Huan also frowned: "Is there any other way besides using machinery?"

"I haven't tried it, the dark sun is very secretive, and the Arctic Circle is a very sensitive place. There is an outpost in Alaska in the west of the Citi country, and a Siberian outpost in the east of the Mao country, and if there is a slight tremor here, both outposts can be monitored. Fiona said honestly.

"Oh, no wonder the sea wolves are going to seal the harbor...... These people are petty in everything, and I don't have to worry about that. Li Huan smiled faintly, thinking that he had to find an engineering team to excavate, since aura and other means could not be used, then explosives were the most scientific.

"Of course, you are my master, and you are no different from anyone else. Fiona slapped her ass at the right time.

Under Li Huan's summons, Shangguan Qing came over to listen to Li Huan talk about the current situation, and she smiled confidently: "It's just directional blasting, it's simple! I'm afraid we don't have so many explosives." ”

"You don't have to worry about this, you just blow it up!" Li Huan was full of confidence, and there were still a lot of munitions stored on the Orca, and there were still unused explosives in his virtual space: "I don't dare to use explosives because I am afraid that someone will know the location and time of their actions, what we want is to alarm them and blow them up as much as possible! Now there's a tough opponent trying to trouble him!"

After speaking, Li Huan vacated two boxes of explosives from the virtual space, Shangguan Qing counted it, there are 30 kilograms of C.4 explosives here, according to the ice explosion, as long as the directional blasting technology is good, repeat it a few times, it is enough to blow up a 200-meter channel. With Li Huan's instructions, Shangguan Qing began to plant explosives.

Li Huan also played C.4, but he was an amateur, far worse than Shangguan Qing. With Shangguan Qing, a technical non-commissioned officer, everything became simpler. Soon, Shangguan Qing placed the explosives, this is a no-man's land in the absolute sense, you can't even see a shadow for hundreds of kilometers, and you don't have to worry about any danger or not, the explosives can be directly detonated after they are placed.

A few minutes later, a continuous burst of explosions began to sound, and clumps of broken ice and snow were thrown out by the blast wave of the explosion. After repeating it several times, when the broken ice, snow and gunpowder smoke cleared, Li Huan stood at the mouth of the cave that extended downwards and looked down, and could no longer see the bottom of the cave.

"It's ...... There is another entrance!" Li Huan stood at the entrance of the cave and stared for a while, and suddenly felt a breeze blowing on his face, and he was overjoyed: "There may be a lot of space inside!"

Li Huan suddenly became excited.

You know, this cave is not ordinary, it may hide one of the biggest mysteries since World War II! As a world-shattering mystery, its significance is even bigger than the curse of the Egyptian pharaohs, the secret of King Arthur's treasure, and the cave! This is not something that can be measured by money, it involves history, politics, military, science and technology, and even the occult.

And this hole that was blown open may well be the answer to everything.

What could be more exciting than finding such a place of historical and mystical significance with your own hands?

Li Huan put down the machine and probed the air flow in the freeze, the air composition is the same as the atmosphere, there is no problem at all: "You can enter, there is no problem with the air at all." ”

With that, he plunged headlong into the cave first.

Li Huan said this, and the three of them naturally followed him in.

As soon as he entered the cave tunnel, Li Huan felt that something was wrong, and a familiar feeling spread throughout his body, just like the first time he crossed the space, it was a feeling, and in an instant, the aura of his whole body disappeared. Like Li Huan, there are also Xiwei and Shangguan Qing, the two of them do not have the experience of aura dissipation like Li Huan, and the two of them were taken aback at the same time: "My aura (holy light) is gone!"

"Well, that's probably the reason why all the spells don't work on this ice......" Li Huan muttered: "But don't worry, we don't have aura, even if someone finds it, they don't have aura." Everyone is just in the same situation, and no one is better than the other. ”

"That'...... If there really is Nazi apocalyptic technology here, will there be zombies or something?" asked Sivir.

"What are you afraid of if there are zombies? Even if you don't have aura, you can't fight a zombie?" Li Huan smiled.

Li Huan said this, Xiwei and Shangguan Qing were right to think about it, even if the door was blocked in the dark, they would lose their aura at that time, and the big deal would be to fight hard. As for zombies or anything, don't worry, under the power of hot weapons, zombies are the dishes delivered to your door.

After entering the ice cave passage and walking through the 200-meter distance that exploded, at the end of the ice cave, there was a cave hall made of rocks! You know, the Arctic continent is full of ice, and there is no land to speak of, and the cave hall that Li Huan came to is formed of natural rocks at a glance, which makes Li Huan amazed: "Even if there is nothing below, this discovery is enough to shock the academic community, they all say that the North Pole is composed of ice blocks, who would have thought that there are caves connected under the ice blocks!"

"This is an ancient volcanic pipeline! You see, there are rock-forming minerals on its rock face, and according to the account of the elder of our family, after the Nazis fled, they did enter the interior of the earth through an ancient passage...... That means we've got it right!" said Fiona.

"If you want to speak, make it clear. "Li Huan is displeased, who can the understand the words of you doctors.

A vampire has become a scholar, speaking professional terms invented by humans, and Li Huan's group of humans still can't understand it, isn't it embarrassing?

"The cave walls have muscovite and minerals, which are standard rock-forming minerals, which are the products of the cooling of volcanic lava...... You give me a light stick and I'll show you. Fiona said that she could see in the dark, more clearly than the infrared night vision mode of the little flyer, and that she must have found something.

Li Huan took out a lighting stick to light it up and handed it to Fiona. Fiona lit her rod and spread her wings and flew towards the top of the cave. The cave hall was about twenty meters high, and when Fiona flew to the top of the cave hall, a layer of dazzling starlight flashed on the top of the cave. The stars were of different colors, dotted with red, yellow, green, and flowing with dazzling light under the light of the light rods and Fiona's movements.

"Oh my God! it's a gem! it's a lot of gems!" Sivir gasped, most of the law enforcement officers of the Sea Hunter Guild were poor, and they had never seen such a scene.

"It's so beautiful, it's a dream world. Shangguan Qing also sighed, she didn't care if it was worth it.

The walls of the entire cave hall are dotted with various colored gemstones, the most beautiful of which is a belt of rock that glows like the Milky Way. Fiona had a great eye, she broke off a shining rock, and found two huge gems from the top of the cave, and this time she gathered the bat's wings and walked in front of Li Huan, respectfully unfolding the things in her hand.

Lying in her hand, apart from two unpolished gemstones, was a thin stone, about the thickness of a biscuit.

"This is mica, it's really a volcanic pipe!" Li Huan understood what Fiona meant.

Mica, a rock-forming mineral with a hexagonal sheet crystal shape, is one of the main rock-forming minerals. Mica crystals have a layered structure inside, so they are lamellar crystals, mainly hexagonal flake crystals, with glittering particles on the surface, and are often used in the jewelry manufacturing industry. The so-called rock-forming minerals generally refer to the minerals that make up magmatic rocks, and there are only more than ten kinds of common rock-forming minerals, such as quartz, feldspar, mica, hornblende and pyroxene.

If a rock-forming mineral is found in a tunnel, it means that this must be an ancient volcanic tunnel, and there is no doubt that since it is a volcanic tunnel, only God knows how deep and long it is.

"What are you doing with two gems?" Li Huan looked at a ruby and a finger-sized diamond in Fiona's hand.

"Master, this is for the two young ladies, let them keep a souvenir. Fiona respectfully handed the gem in her hand to Shangguan Qing and Xiwei.

The two girls accepted it with a smile, Xiwei had never owned such a valuable gem, although Shangguan Qing was not short of money, but the gems in the cave that he found in person were more commemorative than ordinary gems. Li Huan looked at the expressions on the faces of the two women, and then remembered why Xavier said that he might have the best secretary in the world.

The vampire's ability to read words and emotions is far from being comparable to a straight man like Li Huan!

"Not bad...... Li Huan nodded and sighed: "But next time, don't make your own opinions, don't take an example, lead the way." ”

The three of them continued to face forward.

At the end of the cave hall, everyone came to a natural tunnel, and from the tunnel they saw that there was a fork in the road, and there was more than one fork in the road, a total of three. One of the roads is the one that leads straight to the cave hall, and the other two are forks, which are slightly shorter on the main branch. Nature's wonders are unimaginable, and if you don't see it with your own eyes, no one would dare to imagine that there is such a labyrinthine of natural caves beneath this ordinary-looking iceberg.

Li Huan felt a little headache, the underground labyrinth is so big, the four of them must not act separately, God knows what is in this ancient volcanic pipeline? Let Xiaofei's sub-machines explore one by one, although the speed can be accelerated, but the sub-machines can't be too far away from themselves, one kilometer is the limit, and some forks in the road may be more than one kilometer?

"There is also a lot of interference with spiritual power here, and the aura can't ......be used," Li Huan worried.

"Master, I have a way!" Fiona took the initiative to step up again: "I can use sonic imaging to map this tunnel." ”

"Can you still use spells?" Li Huan was stunned for a moment, and raised his vigilance in his heart, in the case that everyone has no aura, only this vampire can still use spells, it will be dangerous.

"Master, I can't use spells either, it's like I have wings, it's my talent. Fiona hastened to explain.

How can you forget that Fiona's body is a big bat and can use sound waves! Sound conducts the fastest and widest speed in solids, and under the Arctic glaciers, there is no other noise, and Fiona can collect the slightest conduction, so that the map of this underground tunnel maze can be completed in an instant.

But after Li Huan was a little, Fiona took the initiative a little too much: "You're not holding back something to harm us, are you? Why are you so proactive?"

After speaking, Li Huan took out that drop of origin blood from the virtual space.

The last time on the icebreaker, Li Huan used Fiona's Origin Blood to teach her a lesson, which had already caused Fiona's cultivation to plummet. If Li Huan did it again, Fiona would probably turn into a bat on the spot.

"The host is not like that. I said, I just want to know the truth of the matter, please trust me!" Fiona finished speaking, gritted her teeth and added: "Besides, after knowing your identity, I don't think I will lose the face of the family by being your slave, don't worry, I won't do anything stupid." If you find anything unusual about me, my Origin Blood is still in your hands, and you can sanction me as you please. ”

"Well, I advise you not to use any other brains, or you will be the first to die. Li Huan nodded, temporarily withdrawing the blood of the origin, and Fiona breathed a sigh of relief.

Fiona didn't delay, and took the initiative to walk into the main tunnel for some distance, and let out a high-pitched cry from her mouth.

This sound was extremely penetrating, just like the air defense sirens that Li Huan had heard. The sound followed the entrance to the main tunnel and quickly spread around, and after about a minute, Fiona had a result.

It's really similar to what I imagined, this tunnel system is a natural labyrinth, and there are so many forks in it that it is outrageous, and I don't know how this and the volcanic pipe were formed at that time, and what the creator thought of building such a huge and complex labyrinth under the glacier. If it weren't for Fiona's sonic imaging to map the terrain and let Li Huan do it, it would have taken two months.

The dozens of forks in the ground turned several times, most of which were dead ends, and the only dozen or so small forks ended up in a slightly smaller cave hall. And at the end of this cave hall, there is a passage that stretches out to where the passage goes in the distance, Fiona says that her sonography extends to the next cave hall is already the limit. The only way to find out what's farther afield is to head to the next cavern hall.

Just go.

Li Huan and the four of them followed the terrain explored by Fiona, and made some small forks in the road towards the second rock hall, and along the way, Li Huan also made hidden marks on each fork. Although Fiona's origin blood is in her own hands, she can't be completely trusted, in case she has the idea of dying together, Li Huan and the three of them won't get lost if they want to come out.

But fortunately, Fiona didn't have any moths, and soon after, Li Huan and the four of them followed Fiona's guidance to the second cave hall. The hall was much smaller than the previous one, and Fiona stood at the entrance to the next tunnel as usual to do a sonogram to find out the terrain.

"It's a good thing you're here with a vampire, she's a natural radar, otherwise we'd be in big trouble...... I'm tired, find a place to sit. Shangguan Qing hammered the hammer leg.

"You will also shout tired!" Li Huanwaner: "There are a few flat stones over there, go and sit over there." ”

In Li Huan's impression, Shangguan Qing has always been a girl who is full of vitality and never knows what tiredness is. It hadn't been two hours yet, and Shangguan Qing was already a little tired. However, he figured it out after thinking about it, when he entered from the ice, Li Huan asked Xiao Fei to make a mark, and two hours later, the group had gone about 300 meters below the ground. The pressure and temperature of the three hundred meters underground changed suddenly, and now the temperature outside has risen to minus five degrees, and everyone has even taken off their winter clothing.

The change of environment will naturally make people feel more tired, not to mention that everyone has been on full alert, in this dark underground, except for Fiona who can see, Li Huan's lighting rod has never been broken.

Shangguan Qing took a few breaths and sat down to take a rest, but as soon as her ass touched the "stone", she only heard a crisp sound of "click", she exclaimed, and the whole person turned backwards. Then, there was a sparse commotion, and where Shangguan Qing was sitting just now, a stray yellow thing rolled out.

"What's wrong!?" Li Huan heard Shangguan Qing's exclamation, and quickly moved the lighting rod over.

"Ouch...... Bullets, why are there so many bullets here!" Shangguan Qing rubbed her ass and got up from the ground, picked up something that flashed yellow light and brought it to her eyes, what is this not a bullet? She quickly asked Li Huan to take the lighting rod and flip the bullet, and the production inscription on the bottom of the bullet and the fire part was clearly visible: "This is a bullet produced in Germany, it is German!"

Li Huan was shocked, yes! Find the right place!
