This main hall is a little bigger than everyone imagined. Xiao Ran and the others now followed Ao Guang and others through the side hall and then walked around a corridor before arriving at the mountain wall behind. . It is said to be a mountain wall, but that is not necessarily the case. Because the original appearance of this mountain wall can no longer be seen at all. The two sides are completely piled up with bluestone slabs, which are smooth and flat. At the top, a few moonstones emit a slight light, allowing everyone to see clearly inside. Case. In front of everyone is a deep passage paved with bluestones. No one knows where it leads yet. Ao Guang did not introduce him, but just walked straight down. Xiao Ran and others behind him quickly followed. According to Xiao Ran's guess, this passage was at least three hundred meters long. It took them half a stick of incense to walk, but they didn't even reach the end of the passage. However, the surrounding temperature was getting higher and higher, which made Xiao Ran a little excited. Ao Guang seemed to know that everyone wanted to ask, and without waiting for anyone to ask, Ao Guang smiled and said, "Do you know why we set the alchemy place so deep underground?" "It should be conducive to alchemy, right?!" Xiao Ran said. The person next to me said without thinking. "Haha, you are half right. Refining elixirs here is indeed beneficial to the elixir's success rate, but the main reason is that there is earth fire below. It is precisely because of the earth fire that I can occasionally refine it. It would be impossible to make a sixth-grade elixir just by myself!" Ao Guang said to the people behind him. Seeing the surprise in everyone¡¯s eyes, Ao Guang suddenly smiled with pride. Indeed, there are not many places like Shenhuo Valley where natural earth fire can be used to refine elixirs. Even if it still exists, it is impossible for the sect to use it as a sect¡¯s residence. Therefore, it can even be said that Shenhuo Valley is the only one in the entire Canglan Continent. One family. "Back then, the founder of our Shenhuo Valley sect was a ninth-grade alchemist. Because he discovered the existence of earth fire here, he used this as the sect's residence to establish the sect, thus forming the current Shenhuo Valley. , Tens of thousands of years have passed!" Ao Guang said, his eyes filled with pride. Even Xiao Ran was a little stunned. A sect that has been passed down for tens of thousands of years is not that simple. While everyone was talking, they had reached the bottom of this passage. After walking down the last step, your eyes suddenly opened up. It turned out to be a cave about five or six meters high. The cave is hundreds of meters wide, with passages crisscrossing it. Even Xiao Ran and others smelled the faint fragrance as soon as they came in. "This is the place where my disciples from the Divine Fire Valley refine elixirs. Because of the existence of earth fire, they can continue to refine elixirs as long as there are enough materials." "These stone doors are closed, which means there are already people inside. You guys You will watch me refining the elixir first. After you are familiar with it, you can also choose a stone wall inside to try to refine the elixir." After Ao Guang said this, he chose a place that looked wider. Passage passed. At this time, the rich fire element in this cave has made Xiao Ran and others feel very hot, but the direction in which they are walking is getting hotter and hotter. But few people said anything, because they knew that although it was very hot inside, it also represented the purer quality of the earth fire. However, these people did not notice that a look of ecstasy flashed across Xiao Ran's face just now. Although getting closer and closer, the lotus heart fire in Xiao Ran's dantian began to tremble. And he was still restless. If Xiao Ran hadn't stabilized quickly, I'm afraid Xiao Ran wouldn't be able to eat and walk away now. Fortunately, Xiao Ran stopped the problem as soon as it arose, but he became excited. The Lotus Heart Fire is a different kind of fire. It is agitated here for no reason, and exudes a trace of excitement. Even if Xiao Ran is a fool, he knows that there must be something here that can attract the Lotus Heart Fire, and what can attract it is absolutely It's another kind of strange 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 didn¡¯t walk for long, just a short cup of tea, and then they stopped outside a stone door with a closed stone door. The only difference between the stone chamber and other stone chambers is that the surrounding temperature is significantly higher. As Ao Guang stepped forward and pressed a certain location, a rumbling sound emitted from the stone chamber, and the two stone doors of the stone chamber slowly opened. "Come in, everyone!" Ao Guang said calmly, his voiceNext, I have already walked in first. Behind him, only Xiao Ran and nine other people followed in, while the other few people turned around and left. After several people came in, the door of the stone room slowly closed. This stone chamber is not big, only about 20 square meters and no more than three meters high, but there is no limit to crowding with a few people inside. The stone room is very clean. Except for the stone table with some spiritual herbs placed on the side, there are only a futon and an alchemy furnace. Although this alchemy furnace does not refine elixirs, there is still a strong medicinal fragrance that occasionally comes out, which shows that it is definitely not an ordinary alchemy furnace. After entering, Xiao Ran's mental power immediately locked onto this pill furnace. There is nothing special about this alchemy furnace except that its quality is the only one Xiao Ran has ever seen. However, at the bottom of the alchemy furnace, there is something similar to a boiler cover, and the closer to the alchemy furnace, the higher the temperature there is. . Although the elixir has not been refined yet, the surrounding temperature has already made everyone frown. ¡°This is my master¡¯s alchemy room, what do you think?!¡± Ao Guang proudly introduced it to several people. "Well, it's really good!" Several people nodded quickly, and even Xiao Ran praised it. When Ao Guang heard Xiao Ran's praise, his face showed a proud look. Xiao Ran rarely spoke, and he didn't even have much expression on his face, just an indifferent smile. Ao Guang is still very concerned about this disciple whom he likes very much. "Okay, you each find a seat and sit down. I will start to refine a batch of elixirs for you to see. Everything is difficult at the beginning. Let's refine a batch of elixirs for you to see first. Once you are familiar with it, You can try refining it yourself first." Ao Guang looked at the excited crowd and smiled. After saying this, Ao Guang walked directly to the alchemy furnace and sat down. Seeing that Ao Guang was really planning to make elixirs, everyone around him became quiet. The entire secret room became quiet instantly. Even if a pin dropped on the ground, you could probably hear it. (To be continued.)
