The cave is not gray, hundreds of caves, large and small, like skylights, sprinkle light and shine on this strange cave.

The cave is in the shape of a hole, small at the bottom and large at the top, and the lowest end of the place is the size of a small room, and the dome at the top is a palace-like area.

On the rock wall, tens of thousands of cicadas gathered in groups of three or five, lying on the rock wall, emitting bursts of flickering light.

If you look closely, it turns out that the rock wall is full of intertwined tree roots, entangled with each other, clinging tightly to the rock wall, providing a huge amount of vitality towards the cave.

In the shadows, there was no sunlight, it was pitch black, and only a little blue light was shining, like stars.

"If I hadn't seen those hundreds of millions of cicadas, I wouldn't help but be surprised when I came here, right?" Qi said with a smile.

In the eyes of ordinary people, this tree hole in the Chilling Cicada Sect can probably be regarded as a spectacle.

However, Qi Xian is also a man who has seen the "big world", so he will naturally not be surprised by this situation.

It's just that when he got here, Qi Xian didn't know what to do.

The chilling cicada is actually quite easy to feed, it doesn't need special food, and the chilling cicada that can survive as long as the life force is enough to just let him stay there quietly.

As for what Qi Xian, the caretaker, needs to do?

I guess as long as these chilling cicadas are not stolen, it will be enough, right?

Because of this, the Chilling Cicada Sect will take this task of guarding as a punishment to punish its disciples.

Because sometimes, loneliness is undoubtedly the best punishment!

However, Qi Xian is not afraid of loneliness, and he will not be lonely.

"Come out quickly, little one, it's all your kind here. Qi Xian said.

A small point of light popped out of Qi Xian's clothes, looked at the outside world, and then flew in the air several times excitedly, as if thanking Qi Xian for his gifts.

"Let you be stuffed in your clothes, but it will hurt you, go and have fun. Qi said with a smile.

The little cicada flew twice, and then, it flew violently into the sky, breaking into the originally calm group of cold cicadas, and for a while, the cold cicada immediately stirred, dancing all over the sky, like a headless fly.

Qi Xian didn't care about them, playing with the little chilling cicada's temperament, but he found a bright place to sit down, and took out a book from the duckweed purple jade.

It is still a book that does not have half a word written on the cover, but it is rare that it has not been folded many times, and there are no traces on the thin paper.

Qi Xian opened it curiously, and immediately laughed.

This turned out to be a book of soldiers!

Among the insect cultivation sects like the Han Cicada Sect, someone actually bored and copied a military book and threw it in the Liuhe Residence Photo Building!

Where can insect cultivation and the art of war be compatible?

Insect cultivation is a symbol of the extreme of individual force, and the law of war is a representative of the use of group strength, which can not only be said to be irrelevant, but can even be understood as two things that are opposed to each other!

It is said that there is a "formation technique" in insect cultivation, but after all, it is the combination of vitality, and the manipulation is still vitality after all.

And the art of war is to manipulate everyone!

How could insect cultivators, who had great strength, be bound by a piece of paper art of war? That is, when they arrived on the battlefield, the most tasks were not still mostly acting alone?

"If Senior Brother Chen sees it, he will probably like it very much, right?" Qi said with a smile.

Indeed, for Chen Qingdu, who wants to see the battlefield, this military book is really good. However, for Qi Xian, isn't this thing just a chicken rib?

Qi Xian wanted to put aside this military book and replace it with a serious classic, but he didn't expect that his mind was attracted by four words.

The four very simple words may not be anything in the eyes of others, but in Qi Xian's eyes, these four words almost gave him an urge to hide this book and not let people see it.

Because, these four words are written, "Jing Xiaoyun"!

The owner of the Qionglou Peak Cave, an almost all-round man, Jing Xiaoyun!

This book of war turned out to be written by him?

Qi Xian didn't dare to slack off, immediately turned the next page and studied it carefully.

Without any hint of discipline or any emphasis on coordination, the book seems to ignore these fundamental factors at all.

Is this self-confidence? or pride?

Then he looked down, and Qi Xian's cold sweat couldn't stop falling.

Because, in this book of war, the tactics used are impossible for mortals to complete!

The formation in the air, the use of ice and fire, the sneak attack underground, and the immeasurable change of formation in a short time, how can this military book look like it is used by mortals?

No, it shouldn't be said that.

To be precise, this book of war is not available to people at all!

With tens of millions of troops at every turn, let alone insect cultivation, it is the biggest war in the world, and there is no need for such a military force!

Could it be that this book is just a pipe dream?

Qi Xian shook his head and said to himself, "What kind of character is Jing Xiaoyun, how can he have a fantasy theory, if he hasn't practiced this art of war, how can he write it down?"

The various miracles in that cave mansion made Qi Xian already have ten percent confidence in this Jing Xiaoyun senior who came out of nowhere, but whatever he wrote, he naturally wouldn't think it was wrong.

However, this military book is indeed strange, no matter how Qi Xian reads it, he can't understand it.

The small body hit Qi Xian's head twice, and the little chilling cicada flew around Qi Xian like a general, with countless chilling cicadas, as if he was cheering up Qi Xian.

It's a pity that although the little chilling cicadas have a positive appearance, their flying appearance is really unsightly.

The chaotic formation, the intertwined figures, the movements of these chilling cicadas at this time are actually similar to those flies that smell the smell of food, and there is no room for appreciation at all!

That's it, but Qi Xian can clearly feel that Xiao Hancia is really looking at himself expectantly at this time, waiting for his reward.

"You're doing a good job, not bad......" Qi Xian opened his eyes, didn't look at those chilling cicadas, and said hesitantly.

Xiao Han Cicada obviously noticed that Qi Xian didn't tell the truth, and immediately hit Qi Xian's head hard, but it flew into the air and ignored Qi Xian.

Qi Xian smiled bitterly, but found that the cicadas above his head were still flying, and then he thought that if there was no command from the little cicada, these cicadas would not know what to do.

In fact, after so many days of getting along, Qi Xian also knew that this little chilling cicada was probably the larva of the Xuanling Ice Chilling Cicada.

As for why he was close to him, Qi Xian couldn't figure it out.

However, since Xiao Hancia has such a good relationship with him, Qi Xian naturally doesn't care about its identity.

He was about to use the chilling cicada technique he had comprehended, but Qi Xian suddenly had a flash of inspiration in his mind, thinking, "What would happen if you used this art of war to dominate these chilling cicadas?"

Thinking about it for a lifetime, but he couldn't stop it, Qi Xian hurriedly calmed down and slowly ran the exercises.

In an instant, all the cold cicadas' eyes seemed to be bright, random, and spontaneously gathered, and they were neatly arranged in ten squares, as if waiting for Qi Xian's review.

Qi Xian opened his eyes and slowly followed the formation above the book of soldiers to give instructions to the cicadas.

I saw that these chilling cicadas suddenly turned into five torrents, flying in five non-stop directions, although it was just an ordinary flight, but invisibly, revealing a murderous aura!

It was a murderous aura that came naturally from a tight formation, and it was a murderous aura derived from an invincible formation invisibly!

If someone stood surrounded by these chilling cicadas at this time, unless he had overwhelming strength, he would be surprised to find that he was surrounded by these chilling cicadas, and there was no way to escape!

This is the power emitted by the group in the marching formation, and it is a powerful power that cannot be released by any single individual!

Qi Xian was secretly happy in his heart, randomly, and continued to give instructions to the chilling cicada.

The five torrents merged into one, converging into a huge group of blue chilling cicadas, and under Qi Xian's instructions, they flew towards the sky violently.

Suddenly, he turned his head, and the end was connected, and suddenly turned into a tight formation that could be attacked and defended.

Subsequently, the cicadas scattered into a ball and flew separately, as if they were chaotic again, but Qi Xian knew that although the formation at this time was very chaotic, each of the cicadas corresponded to each other, and it was definitely not the same random flying as before!

The area of the formation instantly expanded dozens of times, spliced into a huge circle, and the circle in the center corresponded to each other, and it was actually encircled!

The cicadas moved slowly step by step, as if they were slowly eating away at their enemies.

And under the cold cicada, the moisture in the air slowly condensed together, freezing into a thin layer of ice!

This is the result of the cold cicadas gathering together, and the cold aura in the body slowly volatilizing, without a trace of active and unexpected power at all!

"Sure enough, it's not wrong, this book of war is really a book of war written with demon insects as soldiers, only those who can master demon insects can use such power!

Qi Xian raised his head and laughed, this kind of power of control, held in his own hands, was really an indescribable sense of comfort.

Rumble!

After a long time, the cicadas once again reformed a huge circle, and the ice they had condensed finally could not support it and fell.

Just halfway down, the ice has been smashed into pieces on the rock wall, there is a loud noise, and there is a sudden ice rain in the cave!

The little chilling cicada has already been stunned, how has it ever seen such a neat exercise?

Under the loud noise, the little chilling cicada immediately came back to his senses, slammed into Qi Xian's head, and shook his body, as if he was talking to Qi Xian.

"Teach me how to make that formation!"
