The room was covered with dust, and the books on the shelves were all turned to ashes by the wind.

How many precious Dan rooms have left the scene, which is regrettable.

However, through the heavy dust, Zhou Yun saw an undamaged ancient book in the corner.

Hundreds of years have passed, time has passed, the seasons have changed, and the ancient books have not been damaged, but are still intact.

This alone is enough to show that this ancient book is extraordinary, and it is very likely that it contains the true inheritance of the owner of the cave.

Su Wanyan also saw it, her eyes flashed, and she was a little surprised.

Zhou Yun walked through the rows of bookshelves and walked straight to the ancient books.

Just by looking at it, you can tell that the materials used in this book are very different from other books.

The writing of this ancient book is deeper, the pages are thicker, and the text on the cover is also written in special ink, which has not been washed away by the years, and is still eye-catching.

"Compendium of Herbs?"

Zhou Yun read out the four big characters on the cover.

When Su Wanyan heard this, her heart was excited, she walked over in two steps, stared at the ancient books, and muttered to herself: "Is it really the Hundred Herbs Compendium?" disappeared for hundreds of years, and the major sects thought that they were damaged, but they never thought that they would see the light of day again today! ”

Looking at Su Wanyan, who was as cold as the moon, showing such a rare mood swing, Zhou Yun could conclude that this compendium of herbs must be quite valuable.

He tentatively asked, "Is this book precious?" ”

Su Wanyan bowed slightly, "It's very precious." The Compendium of Hundred Herbs was compiled by a six-rank alchemist thousands of years ago, recording the characteristics of hundreds of elixirs, which is the basis for the introduction to the path of alchemy. ”

Zhou Yun roughly understood that this book was a record of introducing various elixirs, analyzing the characteristics of various elixirs, and it could be regarded as a basic book for the way of alchemy.

Anyway, it's precious, but it doesn't seem necessary to be so excited, right?

Isn't it just an encyclopedia?

As for it?

Su Wanyan said again: "Don't underestimate the Hundred Herbs Compendium, which not only has elixir analysis, but also more than 100 kinds of pills!" Do you know the value of Danfang? ”

Zhou Yun shook his head, he had never dabbled in the way of alchemy, let alone understood the value of Danfang.

Seeing this, Su Wanyan explained: "The entire Heavenly Sword Sect adds up to only thirty kinds of Danfang, and most of them are nine grades, and there are only six kinds of eight grades and above!" The Hundred Herbs Compendium records not only the Nine Pins of Pills, but also the Seven Pins and the Six Pins, and the Six Pins of Danfang have been cut off in Tiannan Prefecture. Although it may not be too much, it is enough to improve the foundation of the Heavenly Sword Sect's alchemy faction. ”

Zhou Yun nodded slowly, in this way, the Hundred Herbs Compendium is indeed very precious, and in the case of the Six Rank Dan Fang being cut off, it is even more precious, no wonder Su Wanyan is so excited.

"Since the Hundred Herbs Compendium is so useful to you, then I will give it to you."

Zhou Yun flipped through the compendium of herbs at will, and after confirming that the contents were not damaged, he handed it to Su Wanyan.

Give me something so important?

Su Wanyan was slightly stunned, is this trying to please me?

In the Heavenly Sword Sect, there are too many disciples who have curry favor with her.

Zhou Yundao: "What? You don't? ”

"No, no, no! The Compendium of Hundred Herbs was discovered by you, and it should belong to you. Although Su Wanyan wanted it very much, she still insisted on the bottom line.

Zhou Yun smiled: "Since you said it was mine, then I should be able to dispose of it at will, right?" ”

Su Wanyan nodded solemnly, "That's nature." ”

"In that case, I'll give it to you." Zhou Yun took Su Wanyan's Qianqianyu hand, put the Baicao Compendium in her palm, and then showed a shy smile, "This thing is wasted in my hands, and if you give it to you, you can give full play to its value." ”

Su Wanyan was very entangled, but she still accepted it, it meant too much to the sect, "I can't ask for your things for nothing, do you want to worship the Heavenly Sword Sect?" ”

Zhou Yundao: "Of course I do." But I don't want to join the Heavenly Sword Gate like this, I don't like to go through the back door. ”

Su Wanyan said: "This is not a back door, you have made great contributions to the sect, and you deserve privileges." ”

"Then you're welcome!" Zhou Yun readily agreed, "But I can't let others know that it's through the back door through you." ”

Su Wanyan was puzzled, "Why?" ”

"You have too many suitors, if it is known that I have a close relationship with you, then will I not become the target of public criticism, and everyone shouts and beats me?" Zhou Yun smiled shyly.

Su Wanyan nodded seriously, "You are very thoughtful, you really can't let them know about our relationship, it will add a lot of unnecessary trouble to you." ”

"Then let's continue exploring. I don't think this compendium of herbs is the biggest opportunity here! ”

Zhou Yun was thinking about the fire in his heart, and he couldn't wait.

The two of them left the study and continued to wander deeper into the cave.

Soon they came to a quiet room, where there was only a futon, some bookcases and other things, very simple.

Zhou Yun looked around, but found nothing special, so he moved his position.

I have to say that this cave is indeed very large, the corridor is winding around, there are more than ten rooms, all the way over, except for the study, there is nothing.

After walking for a while, the two came to a spiritual field, which was a place where elixirs were planted.

Lingtian has been left untended for hundreds of years, and many of these elixirs have grown into towering trees, and more elixirs have withered and withered.

Zhou Yun was quite shocked, "These elixirs are estimated to be even better than the best!" ”

Su Wanyan glanced around the spiritual field, and couldn't help but shake her head, "The truly precious elixirs were all picked a hundred years ago, and although the elixirs left here are old, they are very ordinary, if you like them, take them all." ”

Not all elixirs are rarer the older they get, they must be cherished, this elixir has a long growth cycle, and it can continue to devour the aura of heaven and earth, making the medicinal properties stronger and stronger.

However, some elixirs do not have this property, and after a long time, they will stop absorbing them, and even their medicinal properties will be lost.

The elixir in this spiritual field is the second kind, which has been grown for hundreds of years, and the medicinal properties are about to be lost, so it is of little use.

Zhou Yun heard Su Wanyan say that the elixir was useless, so he was interested, there were so many medicines picked in Pishan, which one was not stronger than here?

Like an upstart, will he look at a dime on the ground? When you see it, you step on it.

Su Wanyan said: "The stone room behind Lingtian should be the real alchemy room, and it may be the real chance inside. ”

"So what are you waiting for?"

Zhou Yun quickened his pace, passed through the Lingtian, and walked towards the stone room.

Then, as soon as he left Lingtian, a purple fire suddenly burst out of the stone room, with a head of three zhang, opening his bloody mouth and biting down on Zhou Yun!

Zhou Yun was stunned for a moment, and he felt that a terrifying heat wave was coming to his face, hundreds of times stronger than the magma just now, and before he got close, he was drenched in sweat, which was really terrifying.

Su Wanyan on the side was motionless, and she didn't mean to come forward to help.

Because there is no need at all.

I saw Zhou Yun wave his big hand, and the divine fire rushed out, and the giant python was suddenly suppressed by the blood, swaying in the wind, gradually blurring, and finally turned into nothing.

"What python? I don't think it's as good as a small earthworm? Zhou Yun smiled proudly and beckoned to Su Wanyan, "What are you waiting for, come here." ”

Su Wanyan jumped and came to the door of the stone room, "The flame just now is the Dan Fire that this landlord cultivated before his death, and it should have fused some kind of different fire, so it has not dissipated for hundreds of years." That should be your goal. ”

There are many kinds of so-called different fires, all of which are bred by heaven and earth, among which the Samadhi True Fire is the most famous, and there is also the earth's vein Xuanhuo, which is the so-called source of magma, as well as the Netherworld Ghost Fire......

An alchemist must have his own Dan fire, or he can practice through the magic formula, this kind of fire is generally not strong, and the alchemy will not increase.

Either go to find the alien fire between heaven and earth, and after recovering it, turn it into your own use, and you can enhance your attributes when refining the pill.

The flames here are not very rare, and when they cross the tribulation, they intercept the power of the thunder tribulation from the heavenly tribulation and fuse it into the Dan fire that they have cultivated, so as to enhance it.

Later, through hundreds of years of sacrifice and various cultivations, it grew to such a powerful point today.

But it is very ordinary in nature, the power is limited, and it is not a little worse than the divine fire.

It's just that Zhou Yun needs a flame to cover up the divine fire now, and he doesn't need how powerful the flame is, and there is no need for that.

He's not Xiao Huohuo, why do you go to devour different fires all day long? It's so painful!

Su Wanyan told Zhou Yun the judgment in her heart, and Zhou Yun nodded after hearing this, "Although it is a Dan Fire smelted by the Thunder Tribulation, its power is quite acceptable, and if it can be subdued, it will be good." ”

"Let's go, in the stone room, there should be a fire!" Su Wanyan put her slender hand in the stone door and gently pushed it hard.

Squeak squeak!

There was a strange noise, and the stone door was pushed open, revealing the scene inside the stone chamber.

A heavy dust immediately hit the face, mixed with a strong fragrance, more than a hundred times stronger than the fragrance in the outside Dan room!

Su Wanyan waved her hand, dispersed all the dust, and walked into the stone room with random steps.

Zhou Yun followed, becoming more and more impatient.

I saw that the stone room was very empty, only a half-person high pitch-black Dan furnace, the Dan furnace is quite simple, the material is special, it is carved with the image of the four divine beasts of the green dragon and white tiger Vermilion Bird Xuanwu, the four beasts Ding!

In front of the Dan furnace, there was a white bone plate sitting on the futon, and there was a purple flame burning in the white bone body, which seemed faint, but it would not be extinguished for hundreds of years.

This is the tinder!

Su Wanyan and Zhou Yun saluted respectfully to the white bones, expressing their respect for the owner of this place.

Then Su Wanyan walked to the Four Beasts Ding, the source of the fragrance is this Ding, and inside is the biggest opportunity.

And Zhou Yun walked in front of Bai Gu, sat down opposite the plate, and muttered, "Senior, please forgive the junior for disturbing your peace." You have passed away, and the thunder fire will only be dusty if you stay here, and the younger generation will take the liberty to subdue the thunder fire, let it see the light of day again, and continue to write your original glory! ”

"Senior, if you don't speak, I'll take you as a default!"

"Three...... Two...... One! Thank you seniors for your success! Zhou Yun kowtowed.

Su Wanyan's eyes widened, she had never seen such a brazen person!
