This hall is a little bigger than everyone imagined, Xiao Ran and the others now followed Ao Guang and the others through the side hall, and then bypassed a corridor before they came to the location of the mountain wall behind.

It is said that it is a mountain wall, but it is not true.

Because this mountain wall is actually completely unrecognizable, the two sides are completely stacked with bluestone slabs, smooth and flat, and at the top, several moonstones emit a slight light at the top, so that everyone can see the situation inside.

In front of everyone, there is a deep bluestone paved passage, where no one knows for the time being.

Ao Guang didn't introduce it, but just walked down directly, and Xiao Ran and the others behind him also hurriedly followed.

According to Xiao Ran's guess, this passage was at least more than three hundred meters, and they didn't even come to the end of the passage after walking half a pillar of incense.

However, the temperature around was getting higher and higher, which made Xiao Ran a little excited.

It seemed that he knew that everyone wanted to ask, and without waiting for everyone to ask, Ao Guang opened his mouth and smiled: "Do you know why we set the alchemy place so deep underground?"

"It should be beneficial to alchemy, right?!" said a person beside Xiao Ran without thinking.

"Hehe, you're right, the alchemy here is indeed conducive to the pill formation rate, but the main reason is that there is earth fire here, it is precisely because of this earth fire that I can occasionally refine the six-grade spirit pill, if I simply rely on myself to refine the six-grade spirit pill, it is impossible!" Ao Guang said to the few people behind him.

Seeing the surprise in everyone's eyes, Ao Guang suddenly smiled to himself.

Indeed, there are indeed not many places where there is such a natural fire refining pill as Divine Fire Valley. Even if it still exists, it cannot be used as a place for a sect. Therefore, it can even be said that in the entire Canglan Continent, Shenhuo Valley is also the only one.

"Back then. Our Divine Fire Valley Founding Patriarch is a Nine-Rank Alchemist, because he discovered the existence of Earth Fire here, he used this as a sect to establish a sect in the Divine Fire Valley, thus forming today's Divine Fire Valley, and tens of thousands of years have passed since now. Ao Guang said this, his eyes were full of pride.

Even Xiao Ran is a little smacked, a sect that has been inherited for tens of thousands of years. It's not that simple.

While everyone was talking, they had come to the bottom of this passage.

After walking down the last staircase, the eyes suddenly opened up.

It turned out to be a cave about five or six meters high.

The cave is hundreds of meters wide, and the passages are criss-crossed.

Even Xiao Ran and the others smelled a faint fragrance as soon as they came in.

"This is where my disciples in the Divine Fire Valley refine the elixir, because of the existence of earth fire, almost as long as the materials are sufficient, they can be refined all the time. ”

"These stone doors are closed, which means that there are already people inside, and you will watch me refine the pill first. After you confirm that you are familiar with it, you can also come to choose a stone wall inside and try to refine the elixir. After Ao Guang said this, he chose a passage that looked wider and walked over.

At this time, the rich fire element in this cave had already made Xiao Ran and the others feel very hot, but the direction in which a few people walked. The location is getting hotter and hotter.

But none of them said anything, because they knew that it was very hot in it. But what it represents is that the quality of the earth fire is more pure.

However, these people didn't notice that a look of ecstasy flashed on Xiao Ran's face just now.

Although it is getting closer. The lotus heart fire in Xiao Ran's dantian actually began to tremble.

And it is constantly restless, if it weren't for Xiao Ran's stable speed. I'm afraid that Xiao Ran won't be able to eat now and walk around.

Fortunately, he was curbed by Xiao Ran as soon as the problem occurred, but he became excited.

The lotus heart fire also belongs to a different fire, and it is restless here for no reason, and it exudes a trace of excitement, even if Xiao Ran is a fool, he knows that there must be something in it that can attract the lotus heart fire, and what can attract it is definitely another different fire.

Thinking of this, even Xiao Ran became excited.

Fortunately, no one noticed Xiao Ran's appearance at this time, otherwise Xiao Ran wouldn't know how to explain it.

This time, everyone walked for a short time, just a short tea time, and stopped outside a stone room with a stone door closed.

The only difference between the stone chamber and other stone chambers is that the temperature around it is significantly higher.

As Ao Guang took a step forward and pressed it in one place, the stone room emitted a rumbling sound, and the two stone doors of the stone room slowly opened.

"Come in!" Ao Guang said lightly, his voice fell, and he had already walked in first.

Behind him, only Xiao Ran and the other nine people followed, while the other few people turned around and left directly.

After a few people came in, the door of the stone room slowly closed.

This stone room is not big, only about 20 square meters high, but it is not more than three meters high, but a few people in it are not limited to crowding.

The stone room was very neat, except for the stone table with some spiritual grass placed on the side, there was only one futon and a Dan furnace left.

Although this Dan furnace does not refine pills, there is still a strong medicinal fragrance on it occasionally, which shows that it is definitely not an ordinary alchemy furnace.

After coming in, Xiao Ran's spiritual power locked on this Dan furnace for the first time.

There is nothing special about this Dan furnace except that the quality is only seen by Xiao Ran, but at the bottom of the Dan furnace, something similar to a boiler lid is there, and the closer it is to the Dan furnace, the higher the temperature there.

Although the elixir had not yet been refined, the temperature around it had already made everyone frown a little.

"This is the alchemy room for the teacher, what do you think?!" Ao Guang proudly introduced to a few people.

"Well, it's really good!" Several people nodded hurriedly, and even Xiao Ran opened his mouth to praise.

Ao Guang heard Xiao Ran's praise, and his face showed a smug look, Xiao Ran rarely spoke, and he didn't even have too many expressions on his face, just an indifferent smile.

For this disciple whom he likes very much, Ao Guang is still very concerned.

"Okay, you each find a place to sit down, for the teacher to start refining a furnace of pills for you to see, everything is difficult at the beginning, let's refine a pill for you to see, and when you are familiar with it, you can try refining it yourself first." Ao Guang glanced at the excited crowd and smiled.

After saying this, Ao Guang walked directly to the position of the alchemy furnace and sat down.

Seeing that Ao Guang was really planning to make alchemy, everyone around him was quiet, and the entire secret room was instantly quiet, even if a needle fell to the ground, I am afraid that it could be heard. (To be continued......)
