In the classroom.

Bai Ruoxi continued: "originally, there are some situations that you will not be informed until you reach Sanpin.

Why the third grade?

Because the third grade martial arts person has complete hardening of limbs and bones, can fight and retreat, has strong life-saving strength, and has the most basic ability to kill the enemy.

The martial arts of one or two grades have relatively many defects.

Those who harden the upper limb bones and those who harden the lower limb bones. In short, they are not close to the three grades and do not have comprehensiveness. "

This is an annotation for the fact that the third grade is the elite.

"But everyone is the elite of freshmen. The third grade will happen sooner or later, so I can tell you some information in advance."

"Existence has both value, the existence of martial arts, promotion, privilege

All this is based on those who need martial arts! "

Bai Ruoxi no longer smiled and said faintly, "it's not the need of those in power. More importantly, the society needs us. More importantly, mankind needs us!

Therefore, there is Wuda and all kinds of preferential treatment for wuzhe. "

The classroom was suddenly quiet.

The students are not stupid, as if they all feel the tension.

"Grottoes, I don't know if anyone has heard of it?

Of course, even if someone knows, his understanding is limited.

In order to make you people grow up healthily and healthily, there is not much pressure. Even if the elders at home know about it, they rarely disclose it.

Pressure is for those who have the ability to resist. If they don't have the ability, let everyone live a little easier.

This is my idea. As for what others think, I don't know. Everyone has his own mind. "

"No one can tell what a cave is.

I don't know how it came from. Maybe someone knows. At least I don't know. I didn't know the existence of the grottoes until I was third grade. "

"What's the relationship between caves and martial arts? That's what I want to say."

……

Next, the whole classroom was very quiet, only the voice of Bai Ruoxi.

Bai Ruoxi didn't say much, but they all focused on one point - Grottoes!

Bai Ruoxi really doesn't know what caves are.

What she knows is that the grottoes are located underground, as if they were an underground world, but they are different. It seems that they are not underground at all, because the government has organized people to dig. Even if they dig tens of thousands of meters, there is no trace of the grottoes.

But if you say different space, it's not.

Because once there is a change in the grottoes, there will be a response on the surface, and the most intuitive is the earthquake.

According to modern scientific exploration, it may involve higher dimensions and space, and these bairuoxi are not well understood.

According to Bai Ruoxi, caves are all over the world, not just in China.

In China, there are currently 22 entrances to the grottoes.

This is because the cave entrance is not fixed, but may suddenly appear at any time.

In the 1920 earthquake, the third cave entrance was discovered. In the following 88 years, up to now, 19 more have appeared one after another.

Humans can only enter from the cave entrance, not anywhere else.

The world of caves is full of all kinds of dangers, and there are a lot of dangers ready to enter the ground world all the time.

Therefore, there is a warrior with strong single lethality.

Only in these years has the policy of continuously improving the status of martial artists.

……

Bai Ruoxi kept saying that when she stopped, someone in the class said hoarsely, "teacher, do you mean that there is another world under our feet?"

Bai Ruoxi shook his head and said, "I don't know. It may not be under our feet. Its entrance and exit are underground, but the world may not be underground..."

It was a little complicated, but everyone was not brainless and understood what she meant.

A grotto may be a different space, but it just opens the entrance underground.

Where is this space?

Maybe underground, maybe in another dimension, or even the space of the same universe at all.

"Teacher, only when the grottoes are found can there be an increasing number of martial artists. Does that mean that only martial artists can enter the grottoes?"

Bai Ruoxi shook his head and said, "no, ordinary people can enter, but after entering the cave, the heat weapon will lose its original effect

Or I'm not accurate. Let's put it this way. The caves are a little weird.

After entering, you can only give play to your own strength, which comes from your own strength!

You can use fists, swords, or even crossbows.

The source of power should come from itself, not heat, electricity, wind and solar energy. After so many years, according to expert analysis, only the power of Qi and blood can play a role in caves.

All other external energy will lose its effect.

The power source of scientific and technological weapons will be completely ineffective when they arrive in the grottoes. This is the reason for the promotion of the status of martial artists after the grottoes are found. "

"Teacher, what is in the cave? Human? Zombie? Monster? Or other monsters?"

"That's a world..."

Bai Ruoxi's eyes were somewhat complicated and said, "it's a complete world, not a monster cave in a pure sense.

There's everything in it, humans, animals, monsters

In short, except for everything without modern civilization, there is a newly discovered world.

The cave world is not pure destruction... This is not mentioned for the time being.

In short, in the cave world, some people and monsters want to rush out of the cave door and enter our world all the time.

Once, a cave door was destroyed and rushed out by monsters in the cave world, resulting in extremely tragic consequences! "

"Teacher, they enter the ground world. Can't we kill them with thermal weapons or even nuclear weapons?"

Bai Ruoxi reluctantly said, "yes, the government has tried.

At that time, these intruding monsters were killed, and even many were vaporized.

But... "

Bai Ruoxi said in a heavy tone: "however, because of some unknown factors, these monsters in the cave world are reborn!"

"Rebirth?"

"Yes, not on the ground, but in the cave world.

As I said, they also have human beings. Of course, they may not be human, but they are similar to us in appearance and inside.

Some people naturally have looks and looks. Those who have martial arts found that many of the humans who broke into the ground and were killed have resurrected in the cave world!

They're on the ground. They can't be killed at all!

No, they can be killed, but they must be killed by the warrior before they will not rise again.

In the grotto world, monsters killed by warriors will not revive.

Research and analysis may be due to the suppression effect of the power of Qi and blood. Therefore, major scientific research institutions have been developing weapons with the power of Qi and blood as kinetic energy in recent years.

But the power of Qi and blood comes from mankind itself. Once it leaves the human body, it will become a simple blood, which is also the biggest problem perplexing scientific research institutions!

At present, countries may have some results, but the results are not obvious.

Before the invention of mass weapons that can effectively kill the creatures in the cave world, once the cave creatures enter the surface, it will be a disaster for mankind!

We can't wash the ground with a nuclear bomb every time!

If it goes on like that, the whole earth will be finished.

Therefore, the best way to protect the world and mankind is to let the martial arts guard the grottoes, let the martial arts enter the grottoes, go deep into the grottoes, and stifle the possibility of these people crashing out of the ground in advance! "

Fang Ping never asked a question. At this moment, he said in a deep voice: "teacher, why do the creatures in the cave world rush into the surface? Is the living environment in the cave bad?"

"No!"

Bai Ruoxi shook his head and said, "grottoes are what we say. In fact, they are not dark and light in imagination. They are no different from the normal world.

The environment is even better than us. "

"Then..."

"We don't know the specific reason. Over the years, we have also captured some cave creatures, but on the one hand, it's difficult to communicate because we don't know the language

Of course, now some people are learning the language of cave creatures.

The most important thing is that the cave creatures, and the low-level ones don't know the reason.

The first is difficult to capture, and the second is the high-rise of cave creatures. Once captured‘ "Brain" or can be considered as "brain", it will produce brain death.

I don't know whether it is spontaneous or controlled. This is also under analysis. "

Fang Ping continued: "that is to say, we humans have no better way to restrain cave creatures. We can only kill them by warriors to reduce the possibility of cave creatures impacting the surface?"

"Good."

Bai Ruoxi nodded and said, "otherwise, if any cave door is broken through, it will have extremely bad consequences.

The great earthquake is one of them!

If cave creatures break through the door of the cave, they will cause natural disasters and cause a large number of casualties!

Moreover, the biological destruction of Grottoes is very strong. If you are careless, the whole city will be destroyed.

There were such tragedies in history. In the end, they had to be destroyed with weapons of mass destruction. As a result, the environment deteriorated and all cities, humans and cave creatures disappeared.

But cave creatures can be resurrected in the cave world. In this way, we just drink poison to quench thirst, and finally the earth will be destroyed in our own hands. "

"The devil seemed to shake last night..." Fang Ping said.

Bai Ruoxi's face changed slightly and sighed: "yes, this phenomenon is becoming more and more obvious and more.

Almost all of the 22 cave gates have changed now.

Cave creatures are constantly impacting the cave gate. Every time they impact, they will also cause surface vibration. The more severe the vibration is, the closer they are to rush out. Therefore, once surface vibration occurs, we must immediately send a large number of warriors to enter and kill effectively!

They will also die. When they die more, they will retreat. "

"So was Tiannan before?"

"Well, it was quite serious and almost broke through, so we had to ask a large number of martial artists to reinforce. Even so, martial artists were also seriously killed and injured, especially ordinary people..."

Fang Ping hurriedly said, "ordinary people?"

Bai Ruoxi's tone was deep again. "There are ordinary people in the military headquarters. Do you think the military headquarters are all martial arts?

A large number of ordinary soldiers will also be stationed outside the grottoes and rush to the grottoes when necessary.

Although ordinary people are inferior to martial arts, they can form a military array and have strong lethality.

Otherwise, it will be difficult for those who rely solely on martial arts and millions of martial arts to fight together.

At the gates of 22 caves, not all martial artists will enter, and there are a large number of first and second martial artists

There are not many warriors stationed in the grottoes. Only when the situation is critical, the warriors will enter.

In the grottoes, the power of Qi and blood will be more powerful. A third-class warrior can forcibly break through the ordinary military array of grotto creatures... "

"What?"

This time it was not Fang Ping, but a student was shocked and said, "cave creatures also have a military array?"

Bai Ruoxi repeated again, "it's a civilization, not a zombie in your imagination. Do you understand what I mean?"

Fang Ping said again at this time, "civilization? Teacher, you said that all external energy will lose its effect in the grottoes. How can civilization be formed without energy support?

They don't need to eat?

No ignition required?

What about the sun?

Can you really live without the heat provided by the sun? "

"You think it's wrong. The existence of energy is not only these.

In caves, cave creatures have their own exclusive energy system. Have you read novels or TV?

You can understand it as an energy mine. They use this energy mine for lighting and cooking, including the building of weapons. "

Fang Ping's eyes lit up and said again, "can we use this energy mine to build modern weapons and kill?"

"Yes!"

Bai Ruoxi admitted this, but sighed: "but the energy mine is the most important energy source for cave creatures, and the guard is very tight.

Before that, three masters of Jiupin went deep into the cave world and forcibly robbed it.

As a result, a large number of cave creatures were chased by strong people, the last Jiupin fell, and the other two were seriously injured.

It's too dangerous. The energy mines are deep.

Over the years, we haven't thought about breaking in, but as a last resort, don't go deep, because some cave creatures in the depths usually don't hit the cave door.

But once we go deep and trigger the impact of these creatures, human beings will be really dangerous! "

Fang Ping has no doubt now. In short, in short, at present, mankind is at a disadvantage.

On defense!

Kill near the cave gate to effectively reduce the impact of these creatures on the cave gate.

Fang Ping had no doubt, but Fu Changding thought of an important question and immediately said, "teacher, is the cave biological strength very strong?"

"Very strong!"

Bai Ruoxi said heavily, "their ordinary troops, or cannon fodder, generally have the strength of a good environment.

There are as many second and third products as cattle hair.

Of course, there are not too many middle quality and high quality.

And they have a strong regional awareness... "

The crowd quickly showed their listening.

"In other words, there are few cave creatures near the Tiannan cave gate, or they will never go to other cave gates, which is the main reason why we can maintain the status quo.

Human fighters are mobile. We can fully defend and eliminate an area without worrying about the concentration of creatures in all areas. "

With the continuous introduction of Bai Ruoxi, people finally had a general impression of the grottoes.

In the class, some people suddenly realized, some frowned, some were eager to try, and some showed fear...
