When passing through the portal, Su Mu and Su Ye didn't have any special feelings, but the scenery in front of them suddenly changed, and the mountain behind Qingcheng became a strange place.

What caught my eye was a military camp.

The archway of Qingcheng Mountain Xiuzhen University, as well as several other rune array equipment that can provide teleportation, are all protected in the center of the barracks.

24 hours a day, there are soldiers and cultivators who are in charge of guarding here.

The camp was surrounded by a thick wall.

At intervals on the wall, heavy weapons such as machine guns and anti-aircraft guns were installed, and soldiers patrolled back and forth on the wall to observe the surroundings.

These soldiers are fully armed, not only holding guns, but also wearing special helmets and individual armor systems, which looks like a sci-fi feeling.

Most of them are not cultivators, but they have all learned the cultivation techniques in the army, as well as the skills of cultivating the body.

Therefore, even if the foundation has not yet been laid, the physical fitness is much stronger than the average person. At the same time, the weapons and equipment they are equipped with are all first- and second-level card-type magic weapons that can be used by ordinary people.

With these weapons and equipment, their combat effectiveness is also guaranteed.

Under the high walls, there are armored vehicles and tank cars.

The intricate runes on the body of the car all showed that they were not ordinary chariots, but magic-level chariots equipped with powerful cultivation weapons!

In addition to the soldiers, there are many cultivators in the camp.

Most of them are senior brothers and sisters from Qingcheng Mountain Xiuzhen University, in addition to some military cultivators, as well as researchers.

Looking into the distance, you can see that in this secret realm of the cave, there are mountains and rivers, and the area is very large, just like a small world.

It's just that the sky here is a strange dark red, and there is no sun in the sky.

But the biggest difference between here and the outside is that the aura is very strong.

It's just that the aura here has a violent aura, and if it absorbs too much, it will inevitably affect the cultivator's thinking and personality, making him irritable and irritable, his personality changes greatly, and finally he goes mad.

Su Mu couldn't help but be surprised: such a place where the aura was so violent, was actually one of the top ten cave heavens?

The panda and pheasant, who had come a step earlier, stood behind the portal and waited for them, chatting with an officer who greeted them and signing a document.

Seeing the expressions on the faces of the two, the panda and the pheasant knew what they were thinking without asking.

Almost all the students who came to the Nine Chambers Cave Heaven for the first time had such a psychological journey.

Pheasant said: "Actually, it used to be here, but it was not what it is now. At that time, the aura was rich and peaceful, which was extremely beneficial for spiritual practice. But since a hundred years ago, the aura of all the Cave Heaven Blessed Land has become violent, and even some of the Cave Heaven Blessed Land has directly withered and become a desperate death land.

After the aura became furious, it was easy to stay in the cave blessed land to cultivate, and the cultivators had to withdraw.

But after all, the aura of the Cave Heaven Blessed Land is rich, and it is rich in minerals, so it would be a pity to waste it like this. So the Xiuzhen scientists kept studying this problem, and finally thirty years ago, Yuan Lao and the team led by him cultivated a new spirit plant called Pure Spirit Grass. ”

"After the Pure Spirit Grass swallows the violent aura, it can transform them into normal aura. ”

The panda raised his hand and pointed to the side of the camp: "Well, the piece over there is the Pure Spirit Grass." ”

Su Mu and Su Ye turned their heads and looked in the direction of their fingers, and they saw a patch of plants looking at fluffy white flowers, their leaves were thin and long, a bit like reeds, but they grew on land.

The white velvet flowers were covered by transparent glass covers, and the pipes were connected to the glass covers, converging into a large pipe, leading to a huge runic array device next to it.

Panda continued: "The purified aura of the Pure Spirit Grass is released through the flowers. After planting the Pure Spirit Grass on a large scale, the aura in the Cave Heaven Blessed Land has greatly improved compared to before. The equipment over there is to transfer the purified spiritual energy to the outside to meet the cultivation needs of the teachers and students in the school. ”

Su Mu understood.

No wonder the aura of Qingcheng Mountain is thicker than other places, it turns out to be the effect of transferring the aura in the blessed land of the cave.

But in the current aura situation, there is still a big improvement in the results?

How violent did it have to be before?

Su Mu was secretly surprised.

While the panda and pheasant were introduced, they took Su Mu and Su Ye to the outside of the barracks.

Su Ye looked around and asked curiously: "Uncle Xiong, what's going on with this military camp? Could it be that in the Cave Heaven Secret Realm, there are still dangers such as fierce beasts?" But I read what the textbook says, in the Cave Heaven Blessed Land, there should be some spirit beasts and rui beasts with docile personalities and relatively close to people. ”

The panda said without looking back: "What is recorded in the textbook is the situation of the cave heaven and earth in the past. As the aura became more violent, the number of spirit beasts and rui beasts either decreased sharply, or they became violent and murderous, and at the same time, the number of fierce beasts also increased. ”

"In order to prevent the beasts from running out and harming the people, the military has built a military base at the exit of each cave, and it also assumes the responsibility of protecting the safety of the mining team. In many caves, there are minerals that are not available in the outside world, such as special metals, spirit crystals, etc., which are extremely valuable for mining. ”

"Do you see the cultivators over there? Their next assignment is to assist the military in patrolling the cave. Once a fierce beast is found, if the number is small, solve it by itself. If there are a large number, mark the direction and call for fire support.

In addition, it is necessary to patrol to see if there is a spatial gap, and the spatial gap will also allow the fierce beast to slip out, once it is found, it must be reported immediately, and let the rune array and instrument cultivators dispatch to repair or seal the spatial crack. ”

"The troops and cultivators here are rotated regularly to prevent the aura that has not yet been completely purified from affecting the mental ......."

Panda and pheasant, you and I have a word and a word, and the situation here is explained in detail.

Su Mu and Su Ye listened with relish, and had a new understanding and understanding of the secret realm.

These are all things that are not covered in textbooks.

Panda may have become addicted to being a teacher, and after the lecture, he asked: "Xiao Suzi, do you know anything about the secret realm?"

Su Mu really knew something, he recalled the knowledge in the history books, and said: "According to the history books, the secret realm appeared suddenly, and the origin is unknown. In history, there have been two times when secret realms appeared on a large scale.

One time was in the ancient period, because of the lack of documentary records, it is impossible to understand what the specific situation was at that time, but some scholars speculate that those ancient legends, such as Nuwa mending the sky and Houyi shooting the sun, should be related to the secret realm.

The second time was in the Han and Tang dynasties thousands of years ago, when the cultivators had a fierce confrontation with the fierce beasts and evil gods that appeared in the secret realm, and finally destroyed and sealed the sinister secret realm, leaving a better secret realm. The existing caves and blessed lands all appeared during that period. ”

"The back of the book is good. ”

The panda nodded and said, "A hundred years ago, because of the change in the aura of the Cave Heaven Blessed Land, some cultivators predicted that it should be a sign of the large-scale appearance of the third secret realm. Since then, the state has begun to integrate the various schools of cultivation, establish Xiuzhen universities, and cultivate compound cultivation talents, and many magic academies have also been established in European and American countries.

Everyone wants to minimize the damage and maximize the benefits when the third secret realm appears on a large scale. However, a hundred years have passed, and the so-called third secret realm has appeared on a large scale, but there is no news at all. But even so, all countries still dare not relax and are waiting for it. ”

Su Mu really didn't know about the prediction of the large-scale appearance of the third secret realm—the history textbook didn't talk about it.

Today is a long insight, and I heard some secrets from the mouth of the big guy.

After listening to Su Mu's compliment, Panda scolded with a smile: "The secrets of fart, these contents will be covered in your basic class." ”

Su Mu was stunned: "Then why haven't I heard of it?"

Panda shook his head and said, "How long have you been in school? ”

Belch...... That's right, too.

Out of the barracks gate, the panda raised his hand and tore off the pheasant perched on its shoulder, urging: "Don't be lazy, quickly transform." ”

The pheasant snorted and chirped, looking unhappy, but he didn't dare to disobey the panda's orders, took a deep breath, and his body instantly became larger, from a pheasant with only two taels of meat, to a huge - uh - or pheasant.

The panda jumped on the back of the big pheasant, and then beckoned to Su Mu and Su Ye: "Come up." ”

The two hurriedly climbed up, and when they were seated, the pheasant immediately flapped its wings and took off.

The soldiers on the wall of the barracks all knew pheasants, and they had seen a lot of this scene, but they didn't react.

After the pheasant flew in the sky for a while, he suddenly spoke: "Eh, Xiongda, which direction should we fly?"

"Don't you remember the way?" the panda startled.

"Forget ...... Forgot. "The pheasant was a little embarrassed.

The panda didn't bother to complain about it, so he turned his head and asked Su Mu, "Where is your phone?"

"Here. Su Mu hurriedly took out the mobile phone, and the panda clicked into the school APP, and after a while, he actually opened the map of the secret navigation.

He searched the place he was going to and started to navigate, and immediately heard a delicate female voice sound: "Turn left five kilometers ahead and enter the Wukuang area......"

Panda looked disgusted: "What kind of voice bag are you? ”

Su Mu said: "Sister Lin's voice pack, don't you use this, it's very good." ”

"It's not good, change it. The panda quickly changed the voice package of the navigation, and a voice speaking cross talk came out: "Five kilometers ahead...... Hey, do you think you should turn left or right?"

I'll you!

Su Mu has a black line, can this broken navigation be used?
