In the following time, Fang Ping continued to refine his bones and practice the tactics while listening to the lessons of the special training class.

Gradually, the cave had a rough impression in his mind.

And this impression, when the teacher led everyone to Building 2 of the South District of Mowu to see the topographic map, it was three-dimensional.

......

Building 2.

The only thing that exists in the hall of thousands of square meters is a huge sand table, a modern sand table.

The old professor who led the team walked into the hall and said with a smile: "On the third floor is the simulated topographic map of the Demon Capital Cave.

The 4th floor is the topographic sand table of the Donglin Cave, and the 5th floor is the sand table of the East Lake Cave.

At present, Mowu only has the maps of these three places, and the military department has all the maps.

Cavern, just a general term, we prefer to put a prefix in front of it, because the 22 cave entrances are not through.

It may be through, but at least humans haven't penetrated this far, and for so many years, no one has been able to get from this entrance to the next.

And all of us, the next thing we are going to enter is the Demon Capital Cave.

In the cave, you can't use technology, you can't take pictures, and you lose the power source when you bring your mobile phone camera in......

Therefore, these maps are all simulated sand tables made by human beings a little bit of groping, a little bit of detection, and finally summarized. ”

Fang Ping and the others didn't have the heart to listen to what he had to say.

At this moment, everyone is staring at the sand table!

"This is the city?"

"Village, city, so small?"

"What is the proportion of this sand table?"

"The cave is like this, I thought it was ...... It's a bunch of savages, primitive people......"

Many people know that caves, like the earth, have civilizations.

But many people feel that the creatures of the cave are in an era of hair and blood.

But now, as soon as the sand table came out, everyone found that they were wrong, on the sand table, there were many cities, and the conspicuous and tall city walls were telling everyone that the cave was not a savage society.

They have their own civilization, they have their own social system.

It may not be as advanced as the earth, but everyone takes a different route, and this is not a gap between the level of civilization.

......

Fang Ping glanced at it briefly, frowned, and asked softly, "Teacher, the standard on the map is 13 cities, that is to say, the cave of the Demon Capital, can accommodate 13 cities, how big are these cities, and how many are the populations?"

The mentor who led the team shook his head and said, "It's not 13, remember, it's only 13 so far!"

The meaning of these words is completely different from Fang Ping's meaning.

Zhang Ziwei, who was not far away, said lightly: "Maybe we can treat every cave entrance as a world, rather than as a whole."

In the Demon Capital Cave World, we have only detected this distance at present, and the price is extremely heavy.

The three grandmasters of the Demon Martial Arts were all sacrificed in the process. ”

Obviously, she knew more than Fang Ping.

Fang Ping didn't care about this, but frowned: "So, the location where the entrance to the cave appears on the surface does not necessarily mean that it appears in the same position of the cave, this kind of spatial passage may appear irregularly?"

He was a little confused, but the mentor understood.

The old professor smiled and said, "Yes, for example, there is an entrance in Donglin, and the distance from the entrance of the magic capital is 600 kilometers in a straight line.

According to this location, we enter from the entrance of the magic capital, and go all the way to the east, and we should be able to find the entrance to Donglin.

But at present, there are strong grandmasters, who have explored 3,000 kilometers to the east, but still have not found the existence of the entrance, and further east, it is already an endless ocean......

This means that the cave is so big that there is no limit, and it is tens or hundreds of times the size of our earth.

Otherwise, it represents a spatial channel, where it appears randomly, and there is no correlation between the surface and the cave.

There is also a possibility ......"

Speaking of the last possibility, the old professor glanced at Zhang Ziwei: "As Zhang Ziwei said, each cave entrance is actually an independent world...... However, Commander Li of the military department denied this claim.

Commander Li said that he once felt the breath of the strong man inside the entrance of the cave in the east at the entrance of the cave in the north. ”

"Commander Li of the military department?"

Everyone was immediately interested, and the first person on the Huaguo Grandmaster List was Li Zhen, the commander-in-chief of the military department.

"Yes, that's what Commander Li said. The old professor sighed, "This is not good news, we would rather be separate worlds than the Crypt really as a whole."

But Commander Li's words should be true, since he feels it, a powerhouse like him at the level of a great grandmaster will not be wrong.

This also means that the caves, in fact, are connected and in the same world.

The reason why we didn't detect another entrance...... It should be because of the strength, and the reason why the cave is too big.

Just a magic capital cave, 3,000 kilometers to the east and 2,000 kilometers to the west......

East-west span, at least 5000 km!

As for the north and south, when we enter the cave, we will be in the southernmost part, and behind us is also a vast sea, and the sea cannot detect how big it is, and all the strong people who travel far away fall in the sea, perhaps lost their way.

To the north, there is a gathering place for cave creatures, and we can only go about 1,000 kilometers deeper, and after that, we have already entered the depths of the cave, which is extremely dangerous. ”

"The east-west span is 5,000 kilometers, and the limit of north-south detection is now 1,000 kilometers......"

Fang Ping looked at the sand table in front of him, which was similar to a long strip.

Doesn't that mean...... The size of 5 million square kilometers!

Fang Ping swallowed his saliva and said softly: "Teacher, do you mean that just the size of the Demon Capital Cave that has been detected is half of Huaguo University?"

"Not bad. ”

"This is still not fully detected...... Fang Ping swallowed his saliva again, "Then if the detection is complete, an entrance area may be as big as Huaguo?"

The old professor nodded again and said meaningfully: "Maybe it is bigger than Huaguo, this is also a difficult thing to say, what is the depth of the sea in the south, no one knows, what about the depths of the north? In all directions, we have not detected the limit."

So, 22 cave entrances, you can see 22 worlds, that's okay too.

After all, only Commander Li has found the same strong aura at present, indicating that the creatures of the middle and low-level caves are still unable to penetrate the next entrance. ”

"One entrance, one world...... Maybe bigger than Huaguo......"

At this moment, Fang Ping truly understood why everyone regarded the cave as a crisis of annihilation!

It's too big!

In Huaguo, there are currently 22 entrances, even according to the area that has been detected in the magic capital, 22 caves, which is equivalent to the size of 11 Huaguo!

Hundreds of millions of square kilometers in area!

Asia, with an area of less than 45 million square kilometers.

The second largest is Africa, with about 30 million square kilometers.

The third continent, North America, is around 24 million.

As for the other continents, they are even smaller, and the seven continents that have been discovered by mankind so far have a total area of about 150 million square kilometers.

In China, the area of the cave detected alone is close to the size of the earth's land area.

In other countries, it's the same.

At present, the entrance to the cave discovered in the world has detected an area of almost 1 billion square kilometers, which is more than the size of six earth's land areas.

"In such a big place, there are only 13 cities......" Fang Ping suddenly breathed a sigh of relief.

Of the 5 million square kilometers, there are 1,200 prefecture-level cities and nearly 1,000 county towns on the ground in China, and the population is as much as seven or eight billion in the south.

There are only 13 cities in the cave, and no matter how big it is, the population will not be too large.

The old professor also confirmed this: "The population of the cave is not too large, and we can't do in-depth exploration in the back, but from the entrance, the first city, we have dealt with many times.

Among them, the population is about 2 million, and the army is about 200,000, and they have their own social system, and not all of them are soldiers.

They also have ordinary people, a large number of ordinary people.

The population of the Demon Capital Cave is about 30 million or more, and the number of soldiers can be about 3 million.

At the moment, all we need to face is the first city of the Crypt - we have named it Tianmen City. ”

"Heaven's Gate?"

Fang Ping frowned and said, "This name is enough to lift them up." ”

The old professor shook his head and sighed lightly: "At the beginning, maybe everyone had a trace of fantasy, maybe, as the ancestors of Guangsheng Temple said back then, this is the fairy world...... Tianmen ...... Open the Gate of Heaven ......"

"It's a pity ......"

The old professor sighed again and again, but unfortunately, after all these years, the cave has brought only death and destruction, and no one has any extravagant hopes anymore.

This is not a fairy world, just a beautiful fantasy of human beings.

Yu Xianghua said loudly: "Teacher, in this way, all we demons need to face is the opponent's 200,000 combatable soldiers?"

"Just?"

The old professor laughed and said, "Do you know how strong the cave is?

Their combatable soldiers, of which 10% are warriors, have their own warrior army!

An army of pure warriors!

In the place where cold weapons are king, there has always been an army of 20,000 warriors, how terrible it is, you don't understand at all!"

Yu Xianghua couldn't help but say: "Isn't our military department also a warrior army?"

"It's different, the military department has indeed trained a lot of warriors over the years.

The current martial artists of Huaguo, whether they are qi and blood martial artists or actual combat martial artists, the total number of them exceeds one million.

However, the military department is not all, there are many military personnel in the military department, and the total number of military regions is probably not less than 200,000, which is twice as many as the students in the military university.

But the military headquarters needs to garrison 22 entrances, and there are very few of them.

Moreover, the ground society also needs the military department to pacify the cult, and it has delayed some warriors.

There are less than 5,000 military warriors who are actually stationed in the Demon Capital Cave.

So, we've always been on the defensive, not to mention ...... They have 13 cities, even if they really concentrate their efforts and sweep away Tianmen City, then what's next?

We fought a battle with Tianmen City, and we were killed and wounded, and once the cities behind us increased our troops, then we would inevitably be wiped out.

Now in a tug-of-war with Tianmen City, the cities in the rear will not increase troops, the domain awareness of the cave is very strong, and when Tianmen City does not fall into the downwind to ask for help, most of the other cities will sit on the mountain and watch the tiger fight.

From what we have observed, the caverns do not appear to have a centralized central government, with cities as independent units. ”

"In other words, our army and warriors in the cave can only compete with the city of Tianmen......"

"Wrong!"

The old professor shook his head again and said, "It's not a confrontation, it's a reluctant defense, we are not the opponent of Tianmen City."

Of course, this refers to field warfare, and the other side does not dare to attack our garrison with all its might.

First, our garrison is heavily defended, and they have suffered a lot of losses.

Second, at the critical juncture, we dispatched a number of grandmasters to carry out encirclement and suppression, if it were not for the support of the rear city, Tianmen City would naturally not be the opponent of the entire Huaguo.

But our Grandmaster powerhouse can't enter it in a big way, let alone destroy Tianmen City, unless he is sure to join forces against 13 cities.

Not to mention, further north in the 13 cities, there are also terrifying powerhouses.

Once the human grandmasters gather too much, it is very likely that these terrifying powerhouses will be brought out.

The Kyoto Cave was done once 70 years ago, when there were less than 100 Chinese grandmasters and more than 40 grandmasters wanted to exterminate the Kyoto Cave......

As a result, a number of strange and terrifying powerhouses appeared in the depths of the cave.

In the end, it led to the fall of the 16 grandmasters of Huaguo, and that battle also hurt the foundation of Huaguo, and Kyoto Wuda was almost destroyed in that battle, and the president, vice president, and deans of each college were all killed!"

Speaking of the past, the old professor sighed.

Over the years, Kyoto Martial Arts University has had a lot of grandmasters killed in battle, which is actually related to this kind of war.

In the battle of the caves, the martial arts that were established after the establishment of the martial arts joined less, but the Kyoto martial arts university has always been the main force, which has also led to the double digit death of the grandmaster since the establishment of the school.

Fang Ping and everyone felt a little aggrieved.

"So, you can only defend?"

Hit, small-scale can't beat.

On a large scale, if the future of Huaguo is suppressed, even if it is fought, it will at most pacify one or two caves, but in that case, most of the grandmasters and powerhouses of Huaguo will probably die.

What about the remaining cave entrances?

The old professor chuckled: "Don't be so pessimistic, the younger generation is growing up quickly, and the future is still bright."

A few decades ago, how many grandmasters were strong in Huaguo?

But now?

Nowadays, we are getting stronger and stronger, but the progress of the cave is not as fast as ours, so we will always be on the defensive, in order to buy time for future humans.

If you really want to fight, hundreds of grandmasters in Huaguo can at least wipe out three or five cave entrances!

But once the caves are really connected, we have eliminated so many entrances, and the time for a full-scale invasion of the caves will come in an instant.

So we'd rather fight small-scale battles and rely on human lives than go to full-scale war!"

Nowadays, there are more and more strong people, which is visible to the naked eye.

In the past, there were no more than 100 Huaguo Grandmasters.

In the past 30 years, there have been nearly 100 grandmasters!

On average, there are 3 grandmasters per year, which is unbelievable.

Every year there are gurus in the business world, and so does the government.

In this case, in fact, the government is not willing to carry out Armageddon immediately, it is self-defeating, and it can only endure.

Stall!

The more time passes, the greater the hope of mankind, and the final Armageddon still depends on the strong.

And the usual cave mission, cave war, is actually a kind of training, training the strong!

Soldiers and low-grade martial artists sacrificed a lot, that is also a helpless thing, at this time people need to sacrifice, everyone is unwilling, then the destruction of mankind is not far away.

Everyone stopped asking at this moment and began to look at the sand table.

There are 13 cities in the caves, which are distributed in a fan shape.

The southernmost part, where the population of the Demon Capital Cave enters, is the sea, and on this side of the sea, Hua has a station.

Tianmen City is about 80 kilometers away from the station.

It doesn't sound far away, in modern society, you can drive a car and drag race in half an hour.

But in the cave, mainly on foot, such a distance is still quite far, by walking forcibly marching, 50 kilometers a day is considered a strong army, 70 kilometers a day, such an army must be an elite name.

80 kilometers away is Tianmen City, which is also the gateway city of the Demon Capital Cave.

In the rear, there are other cities.

The cave has mountains and water, and everything is there.

The old professor saw that everyone was looking carefully, and said with a smile: "Technology is still very magical, and soon, our 3D three-dimensional map of the cave will be ready, and when the time comes, everyone will be able to feel everything in the cave more intuitively."

And when we enter the cave, we mainly operate within 30 kilometers of the station.

At this distance, we have all done cleaning, and it is relatively safer.

However, the army of Tianmen City is also active, including their warriors, and some of the warriors who are not soldiers are also moving freely, so danger is inevitable.

And in the caves, except for the cave humans, we call them that.

There are many other dangers besides cave humans!

Including their flora and fauna, some animals, even with the power of high-grade powerhouses, the caves, more like the legendary mythical world, these animals and plants may be seen as monsters.

Danger is everywhere.

Similarly, opportunities are everywhere.

Why are humans getting stronger?

It has a lot to do with the Crypt!

Including the manufacture of our various elixirs, the development and utilization of energy stones, and even the creation of some tactics, all of which are related to the caves.

Do you know that a few fifth-grade students of the Demon Martial Arts can progress so fast?

It also has to do with their opportunities in the Crypt!

I won't introduce these one by one, I haven't compiled teaching materials before, because in the past, only three-rank martial artists could enter, and in the early stage, there would be a short training period in the military department.

In the military department, there is a compilation of various materials.

This is also the first time that Demon Wu has opened a second-grade special training class, so we are negotiating with the military department to prepare to print and distribute some cave teaching materials to everyone, go and see for yourself, to deepen your impression......"

The old professor's mouth was dry, and everyone in Fang Ping was fascinated by it.

It turned out that several fifth-grade powerhouses of the Demon Martial Arts had all gained opportunities in the caves.

The pursuit of strength is also what all warriors expect, and the caves are beneficial, and perhaps a key reason for warriors to go forward.

At this moment, the image of the cave is becoming clearer and clearer in everyone's minds.

Fang Ping no longer cares about getting lost.

The cave is not a desert, nor a prairie, there are cities, there are human strongholds, how can it be so easy to get lost.

Thinking of the many benefits of the cave, everyone was a little eager to try it for a while, eager to enter the cave immediately, get the benefits, and break through the third, fourth, or even fifth grades.

And at this moment, a basin of cold water fell from the sky, extinguishing the heat in everyone's hearts.
