The little book demon was ordered to do it.

The width and length of this palace are dozens of zhang, and the area is so vast, Ding Xing feels that there must be many invisible treasures, but to his surprise, the little book demon let the demonic energy permeate the whole hall, and he did not show any utensils.

But the demonic aura was not without effect, at least slightly altered to the murals on the roof of the palace.

The "Moon Escape" recorded in the mural, in addition to the small seal text, there are corresponding pictures, those pictures were originally in a static state, but after the demonic energy was covered, Ding Xing found that the picture seemed to be alive.

Ding Xing's preliminary observation showed that the picture showed a sense of trembling and vibrating, and he was about to use his magic power to re-observe all the pictures.

But I heard the voice of a Taoist from the corner of the palace: "Brother Xing, there is a paper door here, leading to another palace of similar scale, if I guess correctly, this cave house should be built using the direction of the nine-square grid, running such a huge building, supporting it for so many years without collapsing, it must replenish spiritual power all year round, and spiritual power often gathers in the middle palace, which is where the palace eye is, and the location where the insect swarm fled must also be in the middle palace, you might as well take a look first." ”

When Ding Xing heard this, he immediately led Concubine Qiao Xi to move over.

The so-called nine-square grid is often divided into the upper three palaces, the left, the middle and the right palaces, and the lower three palaces, and the number of secret palaces opened up is a total of nine.

There is also a kind of floating nine palaces in the world of cultivating immortals, and the refining is more complicated, because it needs to be superimposed on three layers, there are a total of twenty-seven secret palaces, and they can move each other, which is mysterious and difficult to break, and is indestructible, and it is recognized as one of the strongest defensive palace protection arrays, of course, the consumption of this formation is also very amazing, even the ancestor of the purple mansion is not willing to open it up easily.

The secret palace where Ding Xing is at this time is located in the upper third palace, which is actually very close to the middle palace, but the paper door is arranged in a clockwise direction, so he must go through the first eight palaces in order to finally reach the middle palace.

Considering the distance, when Ding Xing arrived at the second palace, he asked a scissor to slow down: "The palace area is very large, let's pass through one, check one, and finally go to the middle palace, a scissor brother, you continue to inlay the lighting stone." ”

Then he motioned to the little book demon to release his demonic energy.

After this inspection, the situation was no different from the first, the whole palace was empty, and not a single treasure was found.

What's even more infuriating is that the first room is painted with murals on the top of the palace, recording a Xuangong from a paper school, and the second room does not even have murals, and the palace roof is blank.

As they walked through the room, the sense of disappointment grew stronger.

From the second to the eighth, it was all the same scene, there were no treasures, no murals, except for the cold breeze and the occasional insect corpse scattered on the ground, they never encountered anything again.

Originally, Ding Xing guessed that all the treasures of the palace were invisible, but who knew that this was not the case at all.

"I don't understand!"

At this time, several people had already come to the eighth secret palace, and after passing through a paper door, they could reach the middle palace, but they were not in a hurry to enter, because if they did not get a treasure in the first eight palaces, the ninth palace would not have any gains.

I only heard Ding Xing say to a person who cut the Tao: "The cave is so empty, how should the swarm of the book beetle multiply? In the forbidden moon ring of the Rolling Dust Mountain, there is the spirit seed of the paper-making tree, which takes root and sprouts regularly, providing survival rations for the swarm! The number of swarms here is even greater, and the paper-making trees should be planted all over the palace." ”

A scissor hurriedly shook his hand: "Brother Xing, do you know, the paper tree is cold by nature, like the realm of Binghua Mountain, even if the spirit seed can survive, the growth rate will be extremely slow, in the soil of the Moon Paper Country, it can break the ground and sprout in three months, and it may not be three years here! This Jiugong Cave Mansion is definitely not suitable for planting paper trees, and the rations for feeding the book silverfish must have something else!"

Ding woke up and looked back: "What can that be? Even if the spirit paper and spirit books are piled up in the palace, sooner or later the insect swarm will sit and eat the empty mountain, and they must eat living creatures in order to reproduce in the long years." ”

At this moment, the person who cut the road couldn't answer.

For countless years.

The entire palace has been sealed in the iceberg, and after the birth of the book silverfish, it will definitely devour everything it sees and hears in the palace, including the invisible treasure.

This is also the reason why Ding Xing and a few people walked along the way and couldn't see a single thing.

But since the swarm has eaten everything and they have lost their rations, they should have become extinct long ago.

When Ding Xing was discussing with a scissor here, Concubine Qiao Xi had already touched the door of the middle palace, and the cold current was like a violent wind, whirring with a sound, flowing towards the outer door, making her subconsciously raise her arms.

After a few sniffs, she spread her mind out, but she was blocked by the cold snap, she could only detect a few feet away, she was about to take a few steps inside, and suddenly saw a burst of golden light flashing, looking at the shape of that light, like a wild dragon rushing into the sky.

She couldn't help shouting: "Uncle Ding, cut the seniors, come and see, there is a golden dragon in the palace!"

"What a golden dragon, just an earth snake!" This light did not hide the eyes and ears of Ding Xing and a scissor, and the two immediately walked over and entered the paper door side by side.

Concubine Qiao Xi followed with a smile, and she ran to Ding Xing's side: "The background of the earth snake is poor, but as long as you practice diligently, you will have the opportunity to jump into the dragon gate in the future, and you may not be able to transform into a dragon." ”

As she was talking, she saw that Ding Xing's thumb also lit up with golden light, and with a flick of her fingers, she turned into a small golden snake a little feet long, and with a bang, she swept out, as if she was going to find the big earth snake just now.

The more she looked at it, the more curious she became: "Uncle Ding, your ring has become a fine man!"

Thinking that Uncle Ding has raised so many demon beasts, the little book demon is so powerful, this little golden snake's skills must be stronger, she is extremely envious, and when the exploration of this middle palace is completed, she made up her mind to ask Uncle Ding for advice, how to subdue the little snake that can change into a ring, she also wants to raise one.

At this time, a scissor and the little book demon had already completed their errands, one was inlaid with lighting gems on the palace wall, and the other was spewing demonic energy, looking for invisible things.

This time, each has something new to discover.

After passing through eight empty palaces in a row, they finally ushered in a big harvest.

Ding Xing gave priority to the ice well in the center of the palace, the natural spring wells of Binghua Mountain all contained rich spiritual energy, and the source of spiritual power to maintain this Nine Palace Cave Mansion had been found, it was undoubtedly the ice well.

A strange pair of golden scissors hung over the wellhead, and the golden light that had just burst was the source of this knife.

Looking at its shape, the scissors handle is like a snake body, as if it is made from the bones of a certain type of golden snake, which is also the reason for attracting the little golden snake, it smells the same kind of breath, and can't wait to jump on the scissors, and the silk is entangled in the scissors.

Ding Xing walked to the mouth of the well, looked down, and saw that the bottom of the well was densely packed with book silverfish, and their escape direction could be determined at this point, it must be in the leylines deep in the iceberg.

In the underground ice layer of Binghua Mountain, there are many unknown shady plants, flowers and trees, there are many species, and the swarm of beetles is obviously looking for food underground, but they are also afraid of the cold, and after eating their stomachs, they will instinctively return to their nests.

But the golden snake scissors at the mouth of the well are like butcher knives hanging above their heads to them, and once they try to rush back to the palace, the golden snake scissors will attack them.

The golden snake scissors originally guarded the wellhead, but there was an accident halfway through, resulting in half of the blades of the scissors, which may have been bitten off by the insect swarm, or frozen by the cold current in the well, in short, the power was greatly reduced.

To this day, the Golden Snake Shears are unable to stop the swarm from entering and exiting the ice well.

In order to prevent the swarm from rushing out again, Ding Xing needs to add a new suppression weapon, and he will use insect tears instead of golden snake scissors to solve this hidden danger once and for all.

"Brother Xing, the scissors left over from the paper faction, each piece can be cut spirit paper, quickly collect it! Look over there, the laurel spirit paper is filled with several large boxes, and it must also be sealed with the magic power of refining tools with paper, this middle palace is like a paper school refining room!"
