The room was covered with dust, and the books on the bookshelf were all turned into ashes by the strong wind.

It is a pity that so many precious alchemy rooms have sadly passed away.

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

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

This alone is enough to illustrate the extraordinary nature of this ancient book, which most likely contains the true inheritance of the cave owner.

Su Wanyan also saw it, her eyes flickered, and she was also 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 material used in this book is completely 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 with special ink. It has not faded under the erosion of time and is still eye-catching.

"Compendium of Baicao?"

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

When Su Wanyan heard this, she felt excited. She walked over in two steps, looked at the ancient book, and murmured to herself: "Is it really the Compendium of Baicao? It has disappeared for hundreds of years. All the major sects thought it was damaged. They never thought that today,

See the light of day again!"

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

He tentatively asked: "Is this book very precious?"

Su Wanyan nodded slightly, "It's very precious. The Compendium of Hundred Herbs was compiled by a sixth-grade alchemist thousands of years ago. It records the properties of hundreds of elixirs and is the basis for getting started with alchemy."

Zhou Yun roughly understood that this book records and introduces various elixirs, analyzes the characteristics of various elixirs, and can be regarded as a basic book on the art of alchemy.

How should I put it? It is indeed very precious, but there seems to be no need to be so excited, right?

Isn’t it just an encyclopedia?

As for that?

Su Wanyan added: "Don't underestimate the Compendium of Baicao. It not only contains analysis of elixirs, but also more than a hundred elixirs! Do you know the value of elixirs?"

Zhou Yun shook his head. He had never dabbled in the art of alchemy, let alone the value of the elixir.

Seeing this, Su Wanyan explained: "The entire Tianjian Sect has only thirty kinds of elixirs, and most of them are ninth-grade, and there are only six kinds of eighth-grade and above! The Compendium of Baicao records not only ninth-grade elixirs,

There are also seventh-grade and sixth-grade alchemy formulas, and the sixth-grade alchemy formula has been cut off in Tiannan Province. Although it may not be too many, it is enough to improve the foundation of the Tianjian Sect's alchemy sect."

Zhou Yun nodded slowly. In this way, the Baicao Compendium is indeed very precious. It is even more precious when the sixth-grade elixir recipe is cut off. No wonder Su Wanyan is so excited.

"Since the Baicao Compendium is so useful to you, I'll give it to you."

Zhou Yun flipped through the compendium of herbs at random, and after confirming that the content inside was not damaged, he handed it to Su Wanyan.

You gave me such an important thing?

Su Wanyan was slightly stunned, are you trying to please me?

In Tianjian Sect, there are too many disciples who want to please her.

Zhou Yundao: "What? You don't want it?"

"No, no, no! You discovered the Compendium of Medicine, and it should be yours." Although Su Wanyan wanted it very much, she still insisted on the bottom line.

Zhou Yun smiled and said: "Since you said it is mine, then I should be able to do whatever I want with it, right?"

Su Wanyan nodded dullly, "That's natural."

"In that case, I will give it to you." Zhou Yun took Su Wanyan's delicate hand and placed the Compendium of Herbs in her palm, then showed a shy smile, "This thing is wasted in my hands.

Only then can you exert the greatest value."

Su Wanyan was very conflicted, but she still accepted it. It meant too much to the sect, "I can't take your things for free. Do you want to join the Tianjian Sect?"

Zhou Yundao: "Of course I have. But I don't want to join the Tianjian Sect just like that. I don't like to go through the back door."

Su Wanyan said: "This is not a backdoor. You have made great contributions to the sect and deserve to receive privileges."

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

Su Wanyan was puzzled, "Why?"

"You have too many suitors. If it were known that I have a close relationship with you, wouldn't I become the target of public criticism and be beaten up by everyone?" Zhou Yun smiled shyly.

Su Wanyan nodded seriously, "You have considered it very carefully. 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 feel that this compendium of herbs is not the biggest opportunity here!"

Zhou Yun was thinking about Fire Seed in his heart and couldn't wait any longer.

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

Soon we came to a quiet room. There was only a futon, some bookcases and the like, it was very simple.

Zhou Yun searched around and found nothing special, so he moved his position.

I have to say that this cave is indeed very large, with winding corridors and more than ten rooms. I walked all the way through and found nothing except the study room.

After walking for a while, the two came to a spiritual field, where elixirs were grown.

The spiritual field has not been cared for for hundreds of years. Many of the elixirs have grown into towering trees, and many more have withered and withered.

Zhou Yun was quite shocked, "These elixirs are probably 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. Although the elixirs left here are very old, they are very common. If you like them, take them all.

."

Not all elixirs become rarer as they age. You must cherish elixirs. This elixir has a long growth cycle and can continuously swallow up the aura of heaven and earth, making the medicinal properties stronger and stronger.

However, some elixirs do not have this characteristic. Over time, they will stop being absorbed, and even lose their medicinal properties.

The elixir in this spiritual field is the second type. It has been growing for hundreds of years and has almost lost its medicinal properties and is of little use.

When Zhou Yun heard Su Wanyan say that the elixir was useless, his interest waned. There were so many medicines collected in Mangshan, which one was not better than the ones here?

Just like a nouveau riche, would he value a dime on the ground? If he saw it, he would just step on it.

Su Wanyan said: "The stone room behind the spiritual field should be the real alchemy room, and the real opportunity may be inside."

"What are you waiting for?"

Zhou Yun quickened his pace, passed through the spiritual field, and walked towards the stone chamber.

Then, just as he left the spiritual field, a purple fire suddenly burst out of the stone chamber. Its head was three feet long, and it opened its bloody mouth and bit Zhou Yun!

Zhou Yun was stunned, and felt a terrifying heat wave coming toward his face, hundreds of times stronger than the magma just now. He was covered in sweat even before he got close. It was really terrifying.

Su Wanyan on the side remained motionless and had no intention of stepping forward to help.

Because it's simply not necessary.

Zhou Yun waved his big hand, and the divine fire shot out. The giant python was immediately suppressed by its blood, swaying in the wind, gradually disappearing, and finally disappeared into nothing.

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

Su Wanyan jumped up and came to the door of the stone chamber, "The flame just now was the elixir fire that the owner of this place made during his lifetime. It should be fused with some kind of strange fire, so it has not dissipated for hundreds of years. This should be what you must do.

Purpose."

There are many kinds of so-called strange fires, all of which are nurtured by heaven and earth. Among them, Samadhi True Fire is the most famous, there are also Earth Veins Black Fire, which is the so-called source of magma, and Netherworld Ghost Fire...

An alchemist must have his own alchemy fire, or practice it through magic formulas. This type of fire is generally not strong, and there will be no increase in alchemy.

Or you can search for the strange fire between heaven and earth, recover it, and use it for your own use. It can enhance its attributes when refining elixirs.

The flame here is not very rare. It is when the tribulation is overturned, the power of the thunder tribulation is intercepted from the heavenly tribulation, and integrated into the elixir fire produced by one's own practice, thereby strengthening it.

Afterwards, through hundreds of years of sacrifice and various kinds of nourishment, he grew to be as powerful as he is today.

But it is very ordinary in nature and has limited power. It is not even a little bit worse than the divine fire.

It's just that Zhou Yun now needs a flame to cover up the divine fire. It doesn't need to be how powerful the flame is, and it's not necessary.

He's not Xiao Huohuo, why is he devouring strange fires all day long? He's so idle that it hurts!

Su Wanyan told Zhou Yun her judgment, and Zhou Yun nodded after hearing this, "Although it is a pill fire smelted by thunder calamity, its power is quite acceptable. If it can be conquered, it will be good."

"Let's go, there must be fire in the stone chamber!" Su Wanyan placed her slender hand on the stone door and pushed it gently.

Squeak!

A strange noise came, and the stone door was pushed open, gradually revealing the scene inside the stone chamber.

A thick cloud of dust immediately hit my face, mixed with a strong fragrance, which was more than a hundred times stronger than the fragrance in the alchemy room outside!

Su Wanyan waved her hand to disperse all the dust, and randomly walked into the stone chamber.

Zhou Yun followed closely behind, becoming even more impatient.

I saw that the stone room was very empty, with only a dark alchemy furnace that was half a man tall. The alchemy furnace was quite simple and made of special materials. It was carved with the images of the four great beasts of the Black Dragon, white tiger, Suzaku, Xuanwu, and the Four Beast Cauldron!

In front of the alchemy furnace, there is a white skeleton sitting cross-legged on a futon. Inside the body of the skeleton, there is a purple flame burning. It seems weak, but it will not go out for hundreds of years.

This is fire!

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

Su Wanyan then walked towards the Four Beast Cauldron. The source of the strange fragrance was this cauldron, and inside was the greatest opportunity.

Zhou Yun walked up to the bones, sat down cross-legged across from each other, and murmured: "Senior, please forgive me for disturbing your peace. You have passed away, and the thunder and fire left here will only be covered in dust. I have taken the liberty of subduing the thunder and letting it fall."

See the sun again and continue to write your original glory!"

"Senior, if you don't say anything, I will take it as your acquiescence!"

"Three...two...one! Thank you, senior, for helping me!" Zhou Yun kowtowed.
Chapter completed!
