The Library Pavilion is located in the core area of the Luoyun Sect, and although most of the desolate beasts have retreated, there are still a small number of low-level desolate beasts staying.

Moreover, the threat did not come only from the desolate beasts, but more from the monks of the Falling Cloud Sect.

Most of the high-ranking monks in the sect were attacked and killed by the desolate beasts, and the rest should flee in all directions.

Now in the Luoyun Sect, there is a mess, and killing people is not a strange thing at all, not to mention, Yang Yu and the little fat man are both outer disciples, and in the eyes of the inner disciples, life is cheaper than grass.

Therefore, Yang Yu and the little fat man must do a good job of self-preservation.

Although Qingyun real people have everything, most of the treasures are unusable by Yang Yu, or Yang Yu doesn't know how to use them at all.

After all, Yang Yu's current cultivation is too low, and Yang Yu has never seen any treasures in the previous life, and the treasures of the ancestors of the Jindan period are all good things, if they don't know the use, Yang Yu doesn't want to use them indiscriminately, so as not to cause unnecessary loss......

There are a few flying swords that are indestructible, but Yang Yu doesn't want to hold them in his hands, if he lets the high-level monks see them, they will inevitably lead to death. The few low-level magic swords in Liu Changchun's storage bag were barely usable.

After such a search, Yang Yu found that only the inner armor could be used, so he and the little fat man wore one piece each.

..................

Not long after, Yang Yu and the little fat man came to the core area of the Falling Cloud Sect.

At this time, quite a few monks were already walking outside.

Especially in the warehouse, there were more than a dozen monks gathered, as if they were fighting for something.

"Brother Yu, there are a lot of people in the warehouse, let's hurry up, maybe we can grab some food!" The little fat man has already cultivated to the second level of the Qi cultivation period, so he naturally has some confidence.

"It's enough for us to have desolate beast meat! Anyway, it's just to fill our stomachs!" Yang Yu said: "Now there are a lot of inner disciples gathered in the warehouse, with our cultivation, I'm afraid we won't be able to grab anything!"

"Then where are we going?" the little fat man asked in a daze, a little puzzled.

"Library Pavilion!" Yang Yu glanced at from afar.

The original palatial library has changed beyond recognition, the plaques are crooked, and the forbidden formation may also be gone.

"Brother Yu, let's go into the library to get some high-level exercises!" The little fat man's eyes flashed, and he seemed to understand something.

"Not only the exercises, but all the classics will be taken away!"

On the first floor of the library pavilion, all kinds of classics are scattered all over the place, and some messy names can be vaguely seen.

"Elementary Alchemy"

Early Alchemy

"The Key to Condensation"

Introduction to the Six Bottlenecks of the Qi Training Period

"Chronicles of the Falling Cloud Sect"

"Jingyuan Tuna Technique"

.................. Wait a minute.

The number and scope of coverage are too numerous to count.

Before the catastrophe came, the inner disciples could spend a spirit stone to read in the library for a day, while the outer disciples did not have any chance to approach the library pavilion at all.

The little fat man's eyes lit up, his hands didn't stop, and he put a book into his storage bag.

Yang Yu is the same, in the previous life, Yang Yu spent thirty spirit stones in order to buy "Primary Alchemy", which was all Yang Yu's net worth at that time.

And I only bought a copy, and once I finished reading it, it was immediately incinerated.

However, Yang Yu didn't have any choice, because in addition to buying at a high price, he could only rely on killing people to win treasures.

After the catastrophe struck, all the cultivation items became extremely precious, and no one would easily pass on these classics to others.

Another example is the most common "Chronicles of the Kingdoms", which records most of the Xiuzhen kingdoms in the Xiuzhen realm, as well as the distribution of these domestic sects in Xiuzhen. In many of the major denominations, it is a very common text.

When the Holocaust came, all nations and sects ceased to exist, and the book seemed useless.

However, through the distribution of sects recorded in the classics, the distribution of spiritual eyes can be inferred, and then the existence of high-level desolate beasts can be deduced.

If you have this "Chronicles of All Nations", you can try to avoid high-level demon beasts when walking, otherwise once you strayed into the area of high-level demon beasts, you can only die.

Therefore, just a copy of "The Chronicles of the Kingdoms" costs as many as ten spirit stones.

Every book in this library will become valuable in the near future, but no one realizes it now.

The library is divided into three layers, the classics on the first floor are all ordinary classics, and the second floor can only be entered by core inner disciples and monks in the foundation building period.

As for the third layer, Yang Yu had never heard of it.

After putting away all the books on the first floor, the two went up to the second floor.

The scene in front of them made Yang Yu and the little fat man's faces change slightly.

The entire second floor was full of messes, pieces of broken bamboo slips, and jade slips broken in two, and there was almost nothing to use.

Looks like there's been a lot of fighting here.

At this moment, footsteps came from the stairs on the third floor.

After a while, a white-robed young man walked down from above.

He held a long silver blade in his hand, which was still covered in blood.

After seeing Yang Yu and the little fat man, his voice sank, and he said coldly: "What are you two doing here?"

Yang Yu's face changed slightly, this young man actually had a tenth-level cultivation in the Qi cultivation period, and the silver long sword in his hand should be called the Blood Dragon Sword, which was the magic weapon of Li Kaiyuan, a monk in the foundation building period.

This Li Kaiyuan and the Blood Dragon Sword are very famous, not to mention Yang Yu's outer disciples, even the surrounding mortals know something.

"This young man is holding the Blood Dragon Sword in his hand, could it be that Li Kaiyuan is already dead?" Yang Yu was shocked.

"There are fierce beasts outside, the two of us came here to take shelter, fortunately we met Senior Brother!" Yang Yu was the first to speak.

Once this person made a move, Yang Yu and the little fat man couldn't resist at all, even if they had the protection of Qingyun Zhenren's inner armor, they would only resist a few attacks.

Therefore, Yang Yu immediately said the word fierce beast, Yang Yu and the little fat man are just outer disciples, and the threat brought by the wild beast is greater, this person should not act at will.

"Is there a beast?" the young man's face changed drastically, and after a slight groan, he swung his sword, struck a hole in the wall, and raised a flying sword and flew away.

"Go up to the third floor!" Yang Yu did not hesitate at all, and immediately ran up quickly with the little fat man.

The third floor was also in a mess, a white-haired old man was lying in blood, in addition to the claw marks and bite marks of the desolate beast, there was also an extremely obvious sword wound on the neck.

"This is Uncle Li!" the little fat man couldn't help but shout.

Li Kaiyuan, a monk in the foundation building period, who was high in the sky, actually died here?

Yang Yu only glanced at it, and then looked away.

The root cause of the death of this foundation building monk should be the work of a powerful desolate beast. However, he died directly, because he should have been killed by the young man just now with the blood dragon sword.

Speaking of which, the more high-level the monk, the greater the probability of falling in the catastrophe, because on the first night of the catastrophe, the desolate beasts were like crazy, frantically attacking the monks with strong spiritual power, even at the cost of their own lives.

However, a disciple with shallow spiritual power will not be attacked too much.

Since the young man had taken the Blood Dragon Sword, it was impossible not to take Li Kaiyuan's storage bag.

What Yang Yu was interested in was that after Li Kaiyuan fought with a powerful desolate **, he didn't die.

Then it means that this powerful desolate beast was killed by Li Kaiyuan.

A moment later, Yang Yu's eyes saw a gray body pressed under a bookshelf.

"Three-eyed spirit marten!" Yang Yu almost shouted, this is an authentic second-order demon beast, its body is extremely fast, and it is a very difficult desolate beast.

This is exactly what Yang Yu is searching for.

The catastrophe had just struck, and the young man should not have known the preciousness of the corpse of the beast.

So after he took Li Kaiyuan's treasure, he quickly left.

The young man didn't even think that this was simply a matter of sacrifice. The body of the three-eyed spirit marten is much more precious than the storage bag of a foundation building monk.

The inner pill of the three-eyed spirit marten is the rarest inner pill among the second-order demon beasts, and it is a necessary thing for refining the golden pill after the catastrophe.

In the previous life, in order to capture the three-eyed spirit marten, many monks in the foundation building period gathered more than ten people and set up a formation to encircle and suppress.

But there were still several dead and wounded, allowing the three-eyed mink to escape.

Yang Yu guessed that the reason why this three-eyed spirit marten died at the hands of Li Kaiyuan should be that on the night of the catastrophe, the spiritual power exploded, causing the three-eyed spirit marten to have a fierce surname, and he didn't care about his surname at all, and fought to the death with Li Kaiyuan.

Otherwise, with the body of the three-eyed spirit mink, it would never die here so easily.

Yang Yu did not hesitate to put the body of the three-eyed spirit marten into the storage bag.

Then search carefully.

The third floor of the Library Pavilion was the place where the precious classics were stored, and after Yang Yu searched carefully, he found that many important exercises of the sect seemed to have been taken by the young man.

However, there were still some alchemy refining tools left, and Yang Yu was all put into the storage bag.

"Brother Yu, let's go back, what if someone comes again?" said the little fat man with some trepidation.

Yang Yu nodded, and was about to speak, when the words of Qingyun Zhenren came from the sea of knowledge: "Boy, there is a secret treasure in the secret room of the Library Pavilion, don't you want to see it?"

Yang Yu was stunned for a moment, and then said in his mind: "Don't you want to take away my house, how can you kindly remind me of the hidden treasure?"

"Yours, isn't it mine?" Qingyun Zhenren sneered: "In the southeast corner, there is a dark pavilion, in which there is a treasure handed down from ancient times, this treasure cannot be put into a storage bag, with the help of this treasure, you can live a few more days! But if you live enough, you are not interested in this secret treasure, the old man has nothing to say!"

After finishing speaking, Qingyun Zhenren was silent.

Yang Yu hesitated a little.

After a slight mutter, Yang Yu walked towards the southeast corner, and after hitting a few spiritual powers according to the method taught by Qingyun Zhenren.

A blue light flashed, and sure enough, a dark pavilion appeared.

It was actually a disc the size of a millstone, three feet thick.

"Quartet Five Instrument Array?" Yang Yu's eyes couldn't help but flash.

In the previous life, Yang Yu had indeed seen this treasure, and he saw it in the hands of the old man surnamed Gong.

However, unlike what Qingyun Zhenren said, this item can be stored in a storage bag, and it can shrink freely.

The formation of using this treasure cloth array is also very exquisite.

In the previous life, the old man surnamed Gong got the storage bag of Qingyun Zhenren, and then got the Quartet Five Instrument Array, which is definitely not a coincidence.

Yang Yu is very sure that the old man surnamed Gong got this treasure and has a great relationship with Qingyun Zhenren.

As the saying goes, if there is nothing to do, it is either annihilation or theft, Yang Yu will not easily believe in Qingyun Zhenren, let alone touch this Quartet and Five Ritual Array at will.

"This treasure is too heavy to carry!" Yang Yu said in his mind, and immediately beckoned the little fat man to turn around and leave.

"Boy, don't you even have such a surname, these four directions and five ritual arrays, but my Luoyun Sect's sect is the treasure!" Qingyun Zhenren immediately responded.

"Sect Treasure?" Yang Yu sneered and said: "Whoever likes to want it, anyway, I'm not rare, I'll tell the other disciples the news later, let them take it, the inheritance of the Falling Cloud Sect can't be broken!"

"Wait!" Qingyun Zhenren's voice became urgent: "This treasure can control the size of the treasure, I can teach you the method of refining!"

Yang Yu didn't answer, but his footsteps stopped.

Qingyun Zhenren quickly explained the method of refining.

After careful consideration, Yang Yu found that there was nothing wrong with it.

After a slight groan, Yang Yu directly told the little fat man the mantra as it was.

There is no problem with the formula, Yang Yu is afraid that as soon as he comes into contact with this Quartet and Five Ritual Array, there will be some fatal danger, after all, Qingyun Zhenren is in his mind.

The little fat man has no worries about this.

"Boy, are you going to give up this precious sect treasure to others?" Seeing this, Qingyun Zhenren immediately became furious.

Yang Yu sneered, and did not respond, but stared firmly at the little fat man who was refining the Quartet Five Instrument Array.

"You are the most idiotic person in the world, you actually gave such a treasure to others, once this thing is recognized, it cannot be refined again!" Qingyun Zhenren's voice became more and more urgent, and he became more and more annoyed.

The more ruthless Qingyun Zhenren's scolding, the more relieved Yang Yu was.

The refining process of the Four Directions and Five Ritual Arrays was very smooth, and there was nothing wrong with it.

"Ding!" After a soft sound, the large array disc of the grinding disc actually flew into the palm of the little fat man's hand.

It is exactly the same as the array plate in the hands of the old man surnamed Gong back then.

At this time, there were bursts of footsteps downstairs.
