Li Huan thought about it and understood that this may be the first army in human history to form a system to collect supernatural alien objects.

The items they collected were all very dangerous, and the commander at that time probably didn't have the ability to completely distinguish these things, so he could only store them as safely as possible, so he created such a box to isolate spiritual power - and Li Huan could probably guess that such a box might not have been made at that time to prevent outsiders from entering and exploring, but to prevent the things inside from making trouble.

At the end of the day, it's a place dedicated to storing all kinds of dangerous items, and if you don't take good safety measures, this place can collapse at any time due to internal collapse.

"I can't figure out what's inside, but judging by the number, it's supposed to be the singing skull. I'm guessing this skull is some kind of psychic item, so you hold on to your spirit for a while, and if something really goes wrong, I'll pull you back. Li Huan nodded and said, "Then I'm going to open it." ”

"Li Huan, be careful yourself, if it's not what we're looking for, if this thing is very dangerous, then break it if you can. What kind of skull that can sing, I sound like the evil sect ......," Shangguan Qing instructed.

"No problem. Li Huan nodded, sealed it privately, and held the turntable that opened the door with both hands.

The bones that can sing, in Li Huan's imagination, are definitely a thing that uses mental power to confuse others, this kind of thing Li Huan has heard of, but the last time I heard of it was in Grimm's fairy tales. "The Singing White Bones" is a fairy tale included in "Grimm's Fairy Tales", collected and compiled by the Brothers Grimm. It is probably about an elder brother who killed his younger brother and buried his bones on a plain, and after many, many years, the younger brother's corpse decomposed, leaving only a white bone, and some people looked at the beautiful leg bone, so they picked it up and made a flute, who knew that the sound that came out was all the accusation of the younger brother against the elder brother.

Comparing the white bones in the story, Li Huan felt that if this was the skull of Tlaltai Kutli, then this skull might not be singing, maybe it was scolding his mother. But this is not necessarily, in short, you have to open the cabinet first to see what is inside. Thinking of this, Li Huan grabbed the runner with both hands and exerted force in one direction, only to hear the sound of the machine card inside, and a dull "bang" sounded, it seemed that all the machine expanders had bitten into each other, and the wheel also turned to the head.

"Okay, this laser has turned on, I'm going to open it now, I don't know what's inside. You just follow what you just said, as long as there is a slight change in the things inside, you will shoot together, understand?What we are looking for now may be the most dangerous supernatural item in history, God knows if the skull of Tlaltai Cootli is so good at talking to her spiritual power collection......" Li Huan calmed down, pulled out slightly, and suddenly, the boxy welded safe was pulled open. The moment he opened the door, Li Huan's heart tightened, because he saw that the door of this safe was a full thirty centimeters thick, indicating that the contents inside were very dangerous.

In the process of opening the door, Li Huan entered his spiritual power every time he opened a little distance, filling every space inside the safe, so that even if something inside broke out and hurt people, Li Huan could instantly suppress it with strong spiritual power, and even if he couldn't suppress it, he could slow down the momentum - and then handed it to a few partners outside who raised their guns and aimed at them and were ready to shoot.

When Li Huan opened the door of the safe, the mental power of several people was concentrated to the extreme - no jokes, this is a warehouse specially used by the former Soviet Union's national strategic and defense special tactical forces to collect all kinds of dangerous goods, this powerful empire swept the entire earth when it was the strongest, God knows how many dangerous items they got from various places, God knows what this singing skull is, how will it affect people's spirits? The safest is just like what Shangguan Qing said, as long as there is a little abnormality, it will be broken directly.

When Li Huan's spiritual power filled the last trace of space inside, the door of the entire safe was also opened. The contents of this 3x3 meter-thick and 30-centimeter-thick safe have finally been revealed after being sealed in the ground for decades. Inside the safe, is a small wooden box suspended in the air. The four corners of this wooden box, which were pulled and fastened to the four corners of the inside of the safe with iron chains, were suspended in mid-air. The hanging box as a whole is a dark red, this box seems to be carved out of a single piece of wood, although the carving is not very good, but a quaint atmosphere arises spontaneously.

"Box...... Presumably the skull is in the box. Li Huan pondered for a moment: "I'll see, be careful yourself." ”

Li Huan stepped forward a few steps, stroked the box, and suddenly opened it.

That's right, there is a skull in this box, and it is still an incomplete skull, this skull is placed on dark red velvet, which looks extremely demonic, but just at a glance, Li Huan is sure that this is not what he is looking for, because this skull is not a human skull at all, but a substance similar to crystal.

"Crystal skull?" Li Huan looked at the skull in this box and was stunned: "This is the skull that can sing?"

"Li Huan, what kind of crystal skull, is it what we are looking for? Are you looking for the right thing? Do you have anything to do?" Shangguan Qing was stunned in place after seeing Li Huan open the box, and couldn't help shouting: "Is this thing wrong?" You get out of the way and let me break it directly! There are too many evil things here, if we break it, we will find the next one. ”

"No, no, no...... No, I was surprised, this singing skull turned out to be a crystal skull. It seems that the former Soviet Union's National Strategic and Defense Special Tactical Forces have really gotten a lot of things, and this is a thing from the Americas......" Li Huan carefully examined the crystal skull and shook his head: "It's okay, this is not our goal...... But it doesn't seem to be responding at all now, no, if it's a magic weapon, even if there is no aura injected in forty or fifty years, it will still react to my aura......"

After Li Huan pondered for a while, he injected a breath of aura, but this thing still did not react.

When everyone heard this, they immediately came up to see that the crystal skull, that was a legendary treasure - even if it was a fragment, it was a legendary treasure.

There is an ancient legend among the American Indians that there were 13 crystal skulls in ancient times, and these crystal skulls hid information about the origin and death of human beings, which could help mankind solve the mystery of life in the universe. In the fifties of the nineteenth century, the Germans began to collect, and Michel Hadgis was the first to make the discovery. In 2005, the 12th crystal skull was discovered at the site of Palenque. Legend has it that the 12 skulls joined together to inspire the 13th skull, which is a major skull or hologram. In March 2011, the thirteenth crystal skull was found in Germany, and so far, all the thirteen crystal skulls in the ancient legend of the Mayans have been found!

In fact, the rumors of the crystal skull originated in the twenties of the last century.

In 1924, the British explorer Mitchell Hedges discovered a crystal skull in the ancient city of Lubanedon in Central America, which was quite delicate and clean, about 18 centimeters long, 13 centimeters wide and 13 centimeters high, and weighed about 5 kilograms. In shape and construction, it is almost identical to a human head. Strangely enough, although the skull itself has no color, it emits a bright, colorless light, like the aura of the moon at night. If you put it in a room, there will be some kind of sound coming from all around the room from time to time. The sound was not like the sound of a musical instrument, but more like a soft singing sound coming from a human voice

The sound was accompanied by loud and melodious silver bells.

It is said that the crystal skull also stimulates the central nervous system of the human brain, causing people to produce five senses: taste, touch, smell, sight and hearing. When one looks at the head, there is a noticeable change in color and transparency, and there is a fragrance that emits a fragrance that makes the viewer hear, evokes the imagination, and makes the person feel thirsty. Anyone who stands in front of a crystal skull and meditates has these feelings, and at the same time feels a certain pressure on their body and face. If a person with sensitive senses places his hand near the skull, he will feel a special tremor and thrust, and the hot and cold sensation of the hand varies depending on the position of the hand on the top and bottom of the skull.

In addition to the rhythmic ding-dong sounds and the slight breathing of people, there are various mysterious sensations and sounds that appear around the house. Strange cormorant cries and various other minor sounds can also be seen at night. Dr. Doront once said of the crystal skull, "The skull is always in constant motion, and its transparency and color are constantly changing. The front part of the skull sometimes becomes blurred, like a soft marshmallow, and the middle part of the skull sometimes becomes very transparent and clear, giving the illusion of a large hole in the visual world. The crystal color of the entire skull changes to patches of green, violet, amber, red, fuchsia, blue, etc. The skull also has a hypnotic effect on most viewers. ”

There is also a crystal skull in the British Museum, and since the crystal skull was exhibited in 1898, archaeologists from all over the world have come to inquire about the origin of this treasure. However, the statistics here tend to disappoint them, as there is only one simple caption: "The crystal head, purchased from Citi Nation's New York jewelry store in 1898, may have been the masterpiece of the colonial era Latin American Azuti." ”

The third crystal head is on display at the Musée d'Homme in Paris, France, where they will give you a more detailed introduction. In front of a glass case that is often watched by everyone. The crystal head is scientifically believed to have been made by the Aztecs, a Mexican Indians in the 14th or 15th century. From a historical and religious point of view, it is estimated that it was used to decorate a priest's staff of the Aztecs, thus proving that the Aztecs knew how to appreciate the beauty of crystal and the technology of making it in the Middle Ages. It shows that they knew how to smelt copper very early, because there were many small copper tools made near this crystal head. It appears that the Aztecs carved this crystal head out of copper tools. Among the many listeners, only a few British archaeologists could not understand this explanation, because the Indians of Latin America, who were still living in the dense forests in the forties of the twentieth century, could not imagine that the Indians of Mexico could smelt copper and make copper tools in the 14th or 15th century, and have such a high level of carving skills. It can be seen that the French interpretation of the third crystal human head needs to be recognized by more people, and it remains to be verified by archaeologists.

Shockingly, in the nineties of the last century, two British television producers found a crystal skull in the ruins of an ancient temple in the jungles of Guatemala, which was so exquisite that even the highest modern technology could not be created. Indignant by the incredible supernatural performance of the skull, the two producers then followed up and discovered that all thirteen crystal skulls had been revealed, each of which had an extraordinary provenance. When all thirteen crystal skulls were assembled, the indigenous people of the Americas held a solemn assembly according to the Mayan "sacred calendar", and the high priest Don Alegandro opened the mantra left by the prophet who had traveled through time: "In ancient times, people did not know how to govern themselves, so the Creator sent four prophets here to write down the laws and teach all kinds of knowledge." After completing their mission, they said we were leaving and we were going back to where we had come. The time has come for our light to converge. Before leaving, they said, "Children, don't forget us." We have left behind the wisdom and reason that will assist you. We have left you with divine knowledge. One day we will come back and we will fulfill our mission. “

"Maybe it has something to do with the Aztec Empire, maybe it has something to do with the Aztec Empire, maybe it has something to do with Terratecutli...... And this thing is quite strange, so let's put it away first. Li Huan thought about it and included it in his virtual space.

"Why are you collecting this thing?" Shangguan Qing was curious.

"I don't know...... But it's a rare thing, and besides, I found it to have a peculiarity. Li Huan smiled faintly: "Although it has no aura, and it is completely useless to inject aura, it seems to be able to amplify spiritual power......"

"What does it mean to amplify spiritual power?" Shangguan Qing's understanding of spiritual power is still very shallow.

"It seems to resonate with my mental power. Li Huan pondered for a moment and said, "Just now when I was thinking about whether it was a dangerous object, I injected my spirit, and after injecting spiritual power, I also injected spiritual energy. How to put it, it's not that it doesn't have any effect at all, it seems to be giving me feedback on my mental power. I could clearly feel that it was my spiritual power, but it was not the spiritual power I had just sent out, it seemed to be magnified from the inside...... I'll give you an analogy, it's like if you face a wall and punch out without pain, you can expect the wall to give you a painless feedback, but you don't expect that the wall will give you a hard blow in turn, and your hand will almost break you, that's how it feels. ”

This is what Li Huan just felt, just when he opened the safe, Li Huan was afraid that this thing was in danger, so he probed into the spiritual power in advance to feel whether the skull would burst out and hurt people, but unfortunately, this skull did not move at all, and after being swept by Li Huan's spiritual power several times and infused with aura a few times, there was still no reaction at all- Oh, it can't be said that there is no reaction, there is a reaction, and the reaction is that the skull has fed back all the aura and spiritual power that Li Huan injected before, and it seems to have more than doubled.

This is a very strange phenomenon.

Spiritual power is absolute, it is the materialization of a person's essence and spirit, if the aura of heaven and earth will be magnified because of some heavenly and earthly treasures, spiritual power will not be affected by any image. This strange skeleton can actually amplify spiritual power, this is simply too strange - anyway, this has been sealed underground for almost fifty years, and it has been eating ashes for almost fifty years, Li Huan put it away casually, because of this strange attribute, maybe this thing will be of great use in the future - anyway, Li Huan has already collected an artillery, and if he collects another skeleton, it will be considered an autumn wind.

After listening to Li Huan's explanation, Shangguan Qing and the others seemed to understand whether they understood or not, in the part of the high-level cultivators' explanation of spiritual power, they were purely confused, in short, Li Huan said that it was useful, then take it, anyway, this is something that the former Soviet Union scavenged from all over the world, and now that Li Huan has taken it, it can be regarded as a good way to take it.

Since it's not this...... That's only the last box left.

"Then let's go see the next one?" Shangguan Qing said, "Then there is only one." ”

It was not difficult to find the map, and the four of them quickly found the remaining box. This box looked smaller than the first box, and Li Huan still injected a spiritual force, but he still didn't feel it at all. Obviously, this box is also made of some kind of special metal, which is used to eradicate spiritual power and aura. Li Huan looked at the seal on the box, this seal was put on in 1972, a few years earlier than the age of the crystal skull in front.

This box is only about 1.5X1.5 in size, but it is more delicately cast. The box was black as a whole, and after Li Huan blew off the dust on the box, he even saw the sparkles on this cast metal. According to the retrieval data, this box

The skull is a terrifying existence that burns 1500 degrees Celsius as long as it sees light, and the box where it is stored is obviously also cast with some kind of high-temperature resistant crystals, just to prevent the contents from running wild.

"It's still as you just said, you aim, wait for the contents of the box, whatever it is, as long as there is any abnormal movement, shoot immediately. Li Huan grabbed the turntable on the box and began to rotate hard.

"Boss, you either stand to the side, and we can aim straight inside. Leon swallowed.

Li Ang and Rodman had never participated in the rainforest battle, and Li Huan deliberately did not let these two participate because with the strength of the two of them, they would be sent to death if they went. Later, after the cultivators returned to the Bay Hotel, the two of them mingled in the crowd every day, and naturally heard some truths about Tlaltai Kutli. It was a terrifying ancient cultivator, a cultivator who had risen to the top in their opinion, and there was no room for resistance in front of Tlaltai Kutli.

"Just aim inside......" Li Huan shook his head and began to turn the turntable.

Click.

Click.

Click.

The design of this safe seems to be a little rougher than the first one, and every time Li Huan turns the turntable, as long as he turns it around, he can hear the sound of a machine expanding inside. The turntable has turned three times, and after the machine has sounded three times, the turntable has reached the end. This cabinet is simpler than the first design, but Li Huan also roughly understands what the designer means - the more delicate the design, the more complex the design, the more complex the design, and a large number of surprise parts will be used to realize it. This cabinet contains a terrifying skull that can turn into 1,500 degrees Celsius, and only a simple machine with a high-temperature resistant material design can ensure that it is foolproof.

After Li Huan turned the turntable to the end, he breathed a long sigh of relief, held the turntable with both arms and made a force, only to hear a "click", and the door was half opened. But at this time, Li Huan's movements were suddenly stunned, and he didn't open the door again, nor did he close the door. He just froze in place, as if he had been frozen.

"Li Huan, what's wrong?" Shangguan Qing was the first to react.

"Boss, boss!" Li Ang shouted twice and then scolded: "Damn, Rodman, change the magazine, the boss doesn't seem to be responding, let's go and pull him away!"

Li Ang said, with a shake of one hand, the loaded magazine was shaken off, and then the other hand was wiped on his waist, and the magazine with a supernuclear element warhead was instantly replaced. The three of them were all masters of using guns, and they changed the magazines in less than a second, and the tall Rodman had even reached out to grab Li Huan.

"Don't move!" was about to be pulled by Rodman to Li Huan, Li Huan seemed to wake up: "You all go out, and I'll do the rest of the box by myself." If that chest contains the bones of Tlaltai Kutli, which are recorded to be very hot, you can exit the underground base from now on and wait for me at the entrance of the tunnel. ”

"Impossible! What do you want!" Shangguan Qing shook her head firmly.

"I didn't consult you, I had to do it. Li Huan said firmly: "Li Ang, Rodman, the two of you also go out and accompany Shangguan Qing to leave this place." ”

"No, I can't leave you here alone, not only me, but Leon and Rodman won't leave you here. Shangguan Qing said firmly.

"Hmm......" Li Huan nodded, but suddenly his figure flickered, flashed behind Shangguan Qing, and slashed at her neck with one hand, which happened to be on Shangguan Qing's neck. Li Huan attacked with mental power this time, Shangguan Qing slid down softly without even humming, and Li Huan picked her up and held her in his arms.

"Boss, you ......" Leon and Rodman were taken aback by the sudden turn of events.

"Take her out, it's not a place for you to stay. Li Huan said in a deep voice: "I was afraid that she would entangle with me, so I knocked her unconscious, you two took her to the tunnel mouth, and if you don't get any news from me, you must not come in." ”

"Boss, you just ......" Li Ang was stunned.

"Well......" Li Huan nodded: "That's right, the bones of Traaltai Coutli are in the box, and besides, I was just warned by Traaltai Coutli." You can't stay here any longer, or you'll be charred in an instant as soon as this box is opened. Leave with Shangguan Qing, understand?"

"Rodman, take Miss Shangguan with you. Li Ang suddenly realized: "Leave me your gun." ”

"You don't understand?" Li Huan frowned.

"Of course I understand, but boss, you underestimate me too much, I said, I am where you are, and if you want to hurt you, you have to step over my corpse. I'm not stupid, I've never seen you look so serious, I guess you already felt something, right? You forgot, I'm your bodyguard, I'll open this box later!" Leon said.

Li Huan's face sank, his figure flashed again, and a hand knife slashed at Li Ang's neck, cutting Li Ang down, and then looked at Rodman: "Take these two people out for me, you don't need to sacrifice senselessly, you can't cope with this scene." I don't think I need to cut you down and get the three of you out, right? There's a madman out there clocking us......"

Rodman opened his mouth, what Li Ang said was right, they had never seen that Li Huan had never been so serious, which showed that he had just sensed something unusual. Rodman looked at Li Huan's expression, and finally didn't speak, he knew that the boss was serious, and based on previous experience, the boss's judgment was never wrong. He finally picked up Shangguan Qing on his back, held Li Ang in one hand, and turned to leave.

"Boss, be careful, we're waiting for your news. After Rodman said a word, he quickly ran towards the entrance of the underground base.

"Well, don't come in when I don't have any news to contact you. Li Huan waved his hand.

Just opened the box, only Li Huan knew how much struggle he had experienced in his heart. Why did he fill his mental power while opening the box, the moment he opened the box, he regretted it a little. What he was looking for was the bones of Traaltai Kutli, it was not a joke, the moment Traal Tai Kutli appeared in the sky above the rainforest of the Mo Kingdom, it overwhelmed all the cultivators, to say that her bones were not a problem at all, and if they could be easily suppressed, Li Huan himself would not believe it. At first, Li Huan brought Shangguan Qing in because there was a madman outside, and that madman was still holding two thermonuclear warheads in his hands, so Li Huan felt that this extremely strong underground base was definitely safer than above. But now the situation has changed, it has become different, whether it is the strange items that Li Huan saw in the computer, or the "Thor's Hammer" and a cannonball that he just put into the virtual space, or this crystal skull that can amplify spiritual power and can't figure out its principle at all, Li Huan feels that the underground base is more dangerous than the outside.

Because, the moment he opened the box, it just opened a crack, and a shadow that could only be seen in the spiritual power channel quickly came out of Li Huanhuan's body, and then got into the box. The spiritual power entity of Tlaltai Coutli appeared beside him—but it seemed that Traltai Kutli didn't want others to see her, so only Li Huan could see this terrifying ancient cultivator, and he could still hear her warning in the Spiritual Power Channel.

Tlaltai Cootli appeared the moment Li Huan opened the box, and she said this: "Except for you, if they all leave, they won't survive! Although I can feel my bones, it has been contaminated by other things!"
