A huge stone gate stood in front of Huang Yi, simple and vicissitudes, a desolate and ancient breath came to the face, the stone gate was thousands of meters high, completely blocking the front of this crack.

The width of the stone door is about 500 meters, and the door frame is a stone door frame that is slightly darker than the color of the stone door, and there are some simple patterns on the door frame, which Huang Yi has never seen, giving people a feeling of being natural.

On the stone door, there is no pattern, the huge stone slab closes the door frame, the reason why you can see that it is a stone door, is because you can vaguely see a gap in the middle, it should be able to open, on that door, although there is no pattern, but there are some traces similar to the sword splitting sword sweep, although those traces do not know how many years have passed, but they are still shocking, looking at those traces, as if you can see a god-like strong man lifting a knife towards him, he does not dare to stare at the traces on the stone door for a long time.

There are three steps in front of this huge stone gate, and there are stone piers tens of meters high on the left and right sides of the door.

"Here, how can there be a stone gate? This is the moon, and this stone gate looks like a product of I don't know how many years ago, it can't be made by someone who recently stepped on the moon, but how can there be such a thing on the moon that looks like an intelligent creature made it? Who cast this stone gate? Who left him here? It is difficult to say that there is a ...... on the moon that there are living beings on the moon that humans cannot understand at all"?

Looking at the huge stone gate in front of him, Huang Yi was shocked to the extreme, and his head couldn't even turn for a while, standing there blankly looking at the huge stone gate in front of him.

After carefully observing the stone gate for a long time, Huang Yi frowned slightly, especially the simple patterns on the door frame of the stone gate, which gave him an extremely familiar and unfamiliar feeling, but he was sure that he had never seen this kind of pattern at all.

After carefully combing through the memories in his mind, Huang Yi suddenly remembered that the pattern on the bronze ancient monument that rose from the ground in the distance of Black Mountain Fort was somewhat similar to the pattern on the door frame of the stone gate!

It's just that the pattern on the bronze monument is thousands of times more complicated than the pattern on the stone door, and the pattern on the stone door is simply a simplified version of the pattern on the bronze monument!

"What the hell is going on? What is the connection between the ancient bronze monument that sank into the ground and disappeared on the earth and this ancient stone gate? This must be something left over from ancient history, is it difficult to say that there is really something in the history of human beings on Earth that is incomprehensible and has not been handed down at all"?

At this moment, I don't know why, a strange feeling rose in Huang Yi's heart, it seems that behind the brilliant historical civilization of human beings, there seem to be some unknown things!

The huge stone gate was simple but not simple, standing in front of Huang Yi, as if the crack in the depths of Huang Yi was stretched open by the stone gate at this time.

Reach out and touch the stone under your feet, it's just an ordinary stone, there is nothing special, but it's still the same sentence, how can there be such a stone gate in this place? Who minted it?

This kind of thing is destined to be unanswered, and after looking at the stone gate in shock for a long time, Huang Yi did not feel any crisis, and then flew towards the stone gate tentatively.

The closer he got to the stone gate, the more Huang Yi could feel the shock that the stone gate brought to people's hearts, the stone gate itself did not have any special place, but the vicissitudes of history were like a heavy mountain pressing on the heart and making people breathless.

In the end, Huang Yi came to the steps in front of the stone door, stood for a moment, and then resolutely raised his leg to step on the steps, when Huang Yi's right leg stepped on the first step, his heart was shocked, and he looked down at the stone steps.

He could obviously feel that this seemingly ordinary physical step was actually not ordinary, and that kind of material alone was not comparable to ordinary stones, he bent down and reached out to touch the steps, thought about it, and pressed the steps with his hand, but the steps were not damaged at all, even if he gradually increased his strength, and finally stored the strength of his body to the maximum, even the power of pig iron that could be pinched into soft mud by him could not leave the slightest mark on this seemingly ordinary solid steps, let alone imprints, even stone chips did not get the slightest trace!

"God, what kind of stone is this, how can it be so hard, the hardness of the device, I'm afraid it is harder than a diamond, I don't know how many times, is this still a stone?" Huang Yi said to himself in shock.

Then, considering that the appearance of a huge stone gate here is an extremely unreasonable thing in itself, it is not incomprehensible that this physical step is so strong.

The steps are just steps, except for the incomparably hard, there is no other special place, after repeated inspections without any gains, Huang Yi stepped on the three steps, and then a flat ground dozens of meters wide, extending to the bottom of the stone gate, the material of the solid ground, Huang Yi observed, and the essence of the steps is the same, tried it, it is also extremely hard, and can not make the slightest trace!

Standing in this position, Huang Yi looked up at the huge stone gate, which shocked the soul even more, making people feel extremely small for no reason, especially the shallow traces on the stone gate, the knife splitting the axe and the sword sweep, and even the marks of the fist, although those marks do not know how many years have passed, they are still shocking, giving people a sense of indelible power in the long history, looking at those marks, Huang Yi can even imagine the picture of people who are like gods attacking this stone gate, But they seem to have failed, and failed to open the stone gate!

Walking under the stone gate, Huang Yi thought about it, tentatively reached out to touch the stone gate, and nothing abnormal happened, the stone gate was cold and heavy, and even Huang Yi subconsciously felt that the material of this stone door was harder than the steps, I don't know how many times!

"What the hell is going on? The traces on those stone gates, even if they don't know how many years have passed, still give people a kind of power-shaking power, I'm afraid that even the strong people who surpass the king level on the earth today can't leave any traces on this stone gate, but those 'people' in the past have not been able to open this stone gate, behind the stone door, what is there?"

Huang Yi couldn't help but imagine and guess, but there was no answer to everything, and no one could answer him.

Because he didn't feel any crisis, maybe there was a crisis that Huang Yi couldn't feel, so he stretched out his hand tentatively to push the stone door, but the result was obvious, it was impossible to push the door open, and when he pushed the door hard, Huang Yi even felt a small feeling like an ant wanting to use his own strength to open an anti-theft door.

Taking a few steps back, Huang Yi sat on the ground in front of the stone gate, frowning and pondering, obviously wrong, no matter what the door is, what is the meaning of existence? It is to block the entry of people who do not belong to the owner of the space behind the door, in other words, since it is a door, it can be opened, otherwise why make a door?

Thinking of this, Huang Yi carefully observed the surroundings of the gate, and really let him observe some special circumstances, this gate was indeed opened before I don't know how long ago, which can be seen from the insignificant accumulation of dust at the bottom of the stone gate.

The door was pushed from the inside, separated on both sides, and the little dust outside the door should have been formed when the door was closed, because of the movement, which caused a slight vibration in the doorway, and then the dust was raised and then fell.

It's just that this discovery is meaningless to Huang Yi at all, because it is impossible to judge when this door was opened and how it was opened.

Encountering this kind of strange thing, even Huang Yi's heart was full of curiosity, who cast this door? What's behind the door?

"No, since it's a door, it can be opened, and if it can't be opened with brute force, it will naturally have the skill to open it, just like the anti-theft door invented by humans, which can't be opened by violence, but it can be easily opened with a key......"

Thinking of this, Huang Yi suddenly raised his head and began to observe the gate again, but no matter how carefully he observed, he didn't see any traces of locks on the gate, nor did he see any traces of inserting keys anywhere.

"Since it wasn't opened with a key, it should be something like an 'electronic lock' that was opened", after not seeing the keyhole, Huang Yi began to 'think wildly' again.

However, no matter how much he looked, he could not find any trace of the opening of this door, the pattern on the door frame was only some relief ornaments, nothing special, the façade was bare, and there was no ...... that could be opened except for those shallow traces.

"The moon, also known as the moon, is the earth's satellite celestial body, in ancient times, the moon was called the Taiyin star, and then, according to the legend, the moon lived Chang'e fairy, she raised a jade rabbit, there is a laurel tree on the moon, and there is a Wu Gang who always looks at the laurel tree, and then, there is a moon palace on the Taiyin star, by the way, the moon palace, this will not be the entrance to the legendary Moon Palace, right? In many folklore, there are often people who stand on the earth to observe the moon, say that they have seen the moon palace on the surface of the moon, and swear that they can see a tree ......".

Huang Yi couldn't help but have all kinds of legends about the moon in his mind, and the more he thought about it, the more he felt that something was wrong, and those legends might not be groundless!

In the end, Huang Yi had a thought in his mind that he didn't believe, the so-called Moon Palace that he saw when the earth observed the moon in many folklore wouldn't be the gate in front of him or the things behind the gate that were refracted to the surface of the moon in some way and then observed by people on the earth, right?

Regardless of the disturbances in Huang Yi's mind, he couldn't understand what kind of existence this gate was, and naturally it was impossible to know the way to open this gate.

I don't know how long it took, Huang Yi slapped his head and secretly scolded himself for being really stupid, what kind of world is there now, how can he subconsciously look at things through the eyes of the ancients? I'm stupid, I don't know how many years ago the existence wanted to use brute force to open this stone door, they definitely don't know how to open it, so they can only use brute force, they definitely don't have that much strength, but they can use tools, their eyes can't find some clues, but it doesn't mean that the computer can't find it!

Thinking of this, Huang Yi flipped his wrist and took out a palm-sized communicator from the Void Ring, which was not rationed to him after stepping on the Heavenly Palace spaceship, but the one he used on Earth himself.

As early as the end of the earth, human science and technology have developed to the extent that the communicator is comparable to a computer, and the communicator used by Huang Yi is the latest in recent years.

took out the communicator, and after activating it, Huang Yi directly opened a software inside, and then, on the palm-sized communicator, a green light shot out, and then separated in a fan-shape, scanning the gate and everything around it, in just one second, the gate and everything around it were scanned into a three-dimensional pattern and appeared in Huang Yi's communicator.

There was no surprise, or as expected, that the scanned light could not penetrate the gate, let alone the gate, not even the physical steps outside the gate, but the stone wall that did not belong to the gate was penetrated by the scanned light.

Then, Huang Yi manually operated the communicator, the same place as the mobile phone screen lit up, and a holographic screen appeared in the void, Huang Yi put the communicator on the ground and enlarged the holographic screen to a height of five meters.

Originally, this intelligent communicator was installed with an intelligent system that could be operated by voice control, but unfortunately there was no air here, no sound could be made, and it could only be operated manually, all fool-like, very simple.

Huang Yi enlarged the scanned three-dimensional pattern to a height of five meters, and then generated a three-dimensional map of it, removing the part that did not belong to the gate, and from the traces of the edge position on the three-dimensional picture, Huang Yi said in his heart that it was true, and the part of the gate that went deep into the stone wall and extended out, so he put an end to the way of digging out the ordinary stone outside to 'climb over the wall' to enter the inside of the gate, and this gate was too weird, and Huang Yi did not believe that the way to go over the wall could enter the inside.

The only thing that makes Huang Yi fortunate is that although this gate is also ancient and mysterious, it is not like the bronze monument that appeared on the earth at the beginning that even the scientific and technological equipment could not shoot the picture.

After getting the three-dimensional pattern of the gate, Huang Yi began to operate the equipment to analyze the gate and the flat ground outside the steps and the gate, the structure is unknown, the material is unknown, everything is unknown, and the equipment can't analyze any useful information about this gate at all, it's really too ancient and mysterious.

Reducing the three-dimensional picture of the gate and the surrounding area that is different from ordinary essence to a meter in size, Huang Yi observed around this three-dimensional picture, but still couldn't find any clues, and it was the same if he zoomed in on it, even if he zoomed in to be able to see the subtle texture on the stone ground, he couldn't find any useful information, which was like a cat eating a turtle and having nowhere to put his mouth.

I don't know how many times I turned around the three-dimensional picture, Huang Yi was suddenly stunned, and quickly enlarged the three-dimensional picture and enlarged it again, and found that the flat solid ground outside the gate was not a complete piece, but was paved with a piece of stone slabs one foot square, and there were small gaps in the places where these stone slabs were spliced, these gaps were incomparably tiny, hundreds of times smaller than a hair, and they could not be seen at all when observed by the naked eye.

This discovery made Huang Yi excited, and quickly launched the operation, marking all the combinations between the stone slabs on the flat ground with red lines, and after statistical analysis, the flat ground was paved with a total of 9,999 stone slabs!

However, what shocked Huang Yi even more was that after these stone paved areas were separated, this was clearly a square, and the stone slabs were like a grid between the lines of a Go chessboard!

"These stone slabs are spliced, not a complete piece, but a square like a nine-square grid, will this have anything to do with opening the stone gate?"

After getting this discovery, Huang Yi frowned and pondered, the more he thought about it, the more he felt that it was possible, and then as if he had found something, he completely separated the picture of this square, zoomed in and out and kept observing, and even marked each stone slab with a number individually.

In the end, no matter how he counted, the number of slabs was nine thousand nine hundred and ninety!

However, the problem is that each stone slab is square, one foot square, which is short of a stone slab of 10,000 pieces, and it is wrong to pave a square square, logically speaking, each of these small stone slabs is a square, and the large square ground they spliced into must be one hundred times one hundred, so it is exactly 10,000 pieces, but the question is, now this square is free 9,999 pieces, so in the end, where did the remaining one go?

"The last stone slab is the key, and it must be inevitably related to opening the stone door", Huang Yi said to himself with great certainty in his heart.

But the difficulty of the problem is also here, the whole area is a square, it is reasonable to say that it is a hundred times a hundred small stone slabs, but it is a difference from 10,000 pieces, and it can't form a square at all, but this is a square square, so where did the bad one go?

In order to find the one that is bad, Huang Yi marked each slate with a number, and took out those slate slabs separately to overlap and compare, nine thousand nine hundred and ninety-nine pieces of the same size are exactly the same!

"Obviously it can't form a square square, but it does, obviously it has to be a piece, but after becoming a square, it is exactly the same, what is the reason"? Huang Yi was directly dumbfounded and didn't understand.

After forcing himself to calm down, Huang Yi used his brain comparable to an ordinary computer before the end of the world to think quickly, and the final answer he got was still unreasonable, only two possible stone slabs that were obviously missing a piece could pave such a square, that is, one of them was twice as large as the others, or each of these stone slabs was a little bigger, and the area of the poor one was evenly distributed to the nine thousand nine hundred and ninety-nine pieces!

"Not right"! Huang Yi's heart moved.

Then, he erected the square ground with a three-dimensional pattern, magnified to three meters, so that every stone slab on the ground paved with 9,999 stone slabs could be seen, and the numbers marked on it could be clearly seen, and then he tried to replace the position of two of the stone slabs.

Something magical happened, when he replaced two of the stone slabs, weirdly, the square was incomplete, and one of them was missing at once, and the pattern was divided to the end because of the default program, which is the position in the lower right corner!

"It's amazing, just replace one of the stone slabs, the whole square will be missing, what is the situation"? Huang Yi didn't understand.

Of course, he knows that the bad piece that appears after random replacement is not the location of the missing piece on the real ground, but just the self-arrangement of the program by default, so where is the missing piece on the real ground?

The ground paved with 9,999 stone slabs is like a huge combination lock, you only need to unlock this code and find the less stone slab, I'm afraid it is the key to opening the stone door, but the problem is that without any prompt, moving any of the stone slabs is not a complete square, how to find the missing one? And the real ground can't be destroyed and moved at all, so there's no way to find the missing piece......

In the end, Huang Yi couldn't find the last stone slab if he wanted to break his head, and his heart was extremely entangled, as if he had clearly discovered some secret, but he was separated by a layer of window paper, and the window paper was just uncomfortable if he couldn't open it.

sat on the ground and thought about it for a long time, then Huang Yi stood up, picked up the communicator, and flew to the ground in front of the gate, so that the holographic screen of the communicator was retracted, and a light curtain was projected, like a projector, projecting the complete physical ground in the device, overlapping with the real ground.

"Since moving two of the stone slabs at will cause defects in the entire complete square pattern, and this defect can also be applied to smart devices, in this way, these stone slabs are weird, perhaps, these floors are not immovable, but I can't move, and I'm afraid I have the ability to move, and there may be dangerous things if I move casually, then, I use smart devices to simulate, one piece by one movement comparison, I can always find where the less piece is"!

There is no 'correct way to open', Huang Yi can only use a stupid way, only the operation speed of the device is extremely fast, moving two of them can reflect the complete pattern, and the missing piece will be placed in the lower right corner under the default program, but Huang Yi knows that it is not the right position, if the move is correct, then the position of the really missing piece will definitely appear in the right place!

Although it is weird and evil, the appearance of the gate itself is the biggest unscientific!

The smart device replaced all the slate separately and it only took less than a minute, and the amount of calculation was so large that if Huang Yi did the calculation himself, I am afraid his head would want to explode, but the smart device can complete the calculation quickly...... (To be continued.) )
