Luo Tian under the leadership of Mu Feng, walked towards the back mountain of the Mu family, Luo Tian knew that this side was the forbidden place of the Mu family, when Luo Tian and Mu Yu were very naughty, they often ran around in the yard of his house, but every time Yuhe would tell them that they were not allowed to go to the back mountain.

Luo Tian and Mu Feng came after a while, the mountain behind Mu Yu's house.

Luo Tian found that the back mountain of Mu Feng's house was different from the courtyard, the back was very desolate, and the temperature was relatively high, as for the reason, Luo Tian didn't know what to do.

The two turned left and right in the back mountain, and finally came to a huge cave mouth under the leadership of Mu Feng.

"Tian'er, this is the place where I make alchemy, I'll take you in. Looking at the huge cave in front of him, Mu Feng said to Luo Tiansheng.

"Well, it turns out that there is another hidden mountain in the back mountain of Uncle Mu's house, so I said why didn't you let me play with Xiaoyu when I was a child. Luo Tian sighed as he looked at the huge cave in front of him.

"At that time, if you didn't come to play, it wasn't because I was afraid that you would know the Tao, but for your safety, and besides, it was nothing, and I walked in!" Mu Feng explained to Luo Tian with a smile.

"Yes"

Luo Tian agreed, and followed Mu Feng towards the cave.

The inside of the cave is spacious, and I don't know what the road is, and the temperature in the cave is relatively high, and after a while, the two of them entered the inside of the cave.

After walking for about fifty or sixty meters, Luo Tian found that the temperature inside the cave was at least many times higher than outside, because he was now covered in sweat.

"It's here!" Mu Feng suddenly stopped and said to Luo Tian behind him.

Sure enough, Luo Tian found that the two of them were now in a relatively large cave space, as if it was a very large house, the cave was red, in the middle of this cave, there was a big ding, and next to the ding was a large copper furnace.

There is a humanoid flame burning inside, Luo Tian has never seen such a flame, this mutual flame looks exactly the same as a person, but unfortunately he is only more than twenty centimeters tall, and there is no burning material at all, that is to say, he is a natural existence.

And the heat in the cave should come from it.

Mu Feng looked at the human-shaped flame and Luo Tian said, "This is a strange fire: the psychic demon fire, which I found in a volcanic crater decades ago, and then subdued it and used it for alchemy. ”

"It's amazing, isn't this the heaven and earth spirit thing mentioned in the book?" Luo Tian looked at this humanoid flame and muttered.

Hearing Luo Tian's question, Mu Feng explained to him: Yes, this is the spirit of heaven and earth, this is a different fire, in addition to the different fire, there are also Xuanshui, Xuanlei and foreign land.

Every kind of spiritual creature is very powerful, and the biggest effect of the alien fire is to help people refine pills, refining weapons, and of course, it can also be used for battle.

The foreign land is mainly used to help people cultivate and defend, the Xuanshui is used for healing, and the Xuanlei is used for combat.

However, it is not that only Xuan Lei can improve people's combat effectiveness, and the other three spiritual objects can also be used, but Xuan Lei's is stronger.

Among the four spiritual objects, the most difficult to recover is also Xuanlei, followed by the alien fire, followed by the Xuanshui, and the alien land is relatively easy to recover.

And the grades of these spiritual objects are divided according to the same level as the elixir, but the highest is only the eighth order, and this psychic demon fire is only a third-order spiritual object.

"Oh, there are so many, can you also recover a variety of spiritual objects by yourself?" Luo Tian asked curiously after listening to Mu Feng's explanation.

"This is logically impossible, because water and fire are incompatible, so it is generally difficult for two spiritual objects to be together, but the previous ruler should have recovered a lot of spiritual objects. Mu Feng said again.

"What is the Juggernaut, is it very powerful?" Luo Tian looked at Mu Feng and asked.

"The master is very powerful, that's a very distant thing, there has been no master in this world for many years, and you don't understand what I told you, you still have to cultivate well, and maybe you will have the opportunity to know the Tao in the future." Mu Feng said that a reminiscing expression appeared on the face of the ruler, and he came over and said to Luo Tian for a while.

"Oh, well, how can these spiritual creatures be recovered? Luo Tian looked at Mu Feng and asked with a smile.

"Hehe, you think there are a lot of spiritual things, if the spiritual things can be encountered casually, then it's not called a spiritual thing, these spiritual things are very powerful, and it's not that there are spiritual things that are powerful, you still have to be strong yourself, like this psychic demon fire is just a powerful fire, when I recovered it, I almost made my soul scattered, if it was a more powerful spiritual thing. Mu Feng looked at Luo Tian and said.

"Oh, I see, it seems that I am thinking too much. After listening to Mu Feng's words, Luo Tian already felt that his thoughts were too simple, so he said with a smile.

"Well, that's not the case, for spiritual things it depends on luck and strength, maybe you will be lucky, and you will encounter a few of them that day, but not necessarily. Mu Feng said again.

"How can I have such good luck, but Uncle Mu Feng's alchemy requires these strange fires?"

"Of course not, the different fire alchemy is very convenient, but without the different fire, it can still be alchemy, and it can also practice a very good elixir, but then you need a good fire gathering array, in fact, the different fire is just so low that you don't need to find the fire source, it's not that only the different fire can be alchemy, how can there be so many different fires in this world." Okay, let's stop talking nonsense, I'll teach you fire control next. ”

"What a shame!"

"Well, this set of fire control techniques I taught you is called the Firmament Burning Ding Technique, which is a set of saint-level fire control techniques, which is very difficult, otherwise I wouldn't say that there have been many years, and no one has practiced it, do you want to slowly explore the Dao?" Mu Feng regained a serious expression on his face, looked at Luo Tian and said.

"Uncle Mu Feng, haven't you practiced yet?" Luo Tian asked rhetorically.

"Well, I'm just mastering a little bit of the skin, I'm talking about practice, not that I can control a little flame alchemy casually, even if I can practice it, what I'm talking about is to really master the essence of it, you watch me show you it. ”

"Okay!" Luo Tian heard that Mu Feng was going to demonstrate the Firmament Burning Ding Method for him, so he collected his thoughts, stepped aside intently, and looked at Mu Feng in the middle.

Mu Feng walked to the side of the psychic demon fire, calmed down, and suddenly grabbed the demon fire in the copper furnace with both hands, grabbed the demon fire, threw it into the air, his fingers changed a few handprints, and then pointed to the demon fire on the ground, and the demon fire immediately began to enlarge, until it completely turned into a big fire dragon flying in the air.

"Brush!" Mu Feng's handprint changed again, and the fire dragon also changed, turning into a raging fire, and the flames slowly formed a huge Dan furnace in the air.

Luo Tian was so shocked, this is fire control, this is simply art, Luo Tian was dumbfounded, but the furnace in the air suddenly disintegrated, and the demon fire that turned into a human shape again fell into the copper furnace.

The moment Mu Feng fell, Mu Feng's body softened directly, and he almost fell to the ground, his whole body was drenched in sweat, Luo Tian looked at Mu Feng, and immediately ran over to help him and asked, "Uncle Mu, are you okay?"

"It's okay, I'm just too tired, have you seen it, how about it?" Mu Feng wiped the sweat from his face and asked Luo Tian.

"It's amazing, I like this fire control technique very much, Uncle Mu, I don't think you have used much physical strength, how can you be so tired?" Luo Tian looked at Mu Feng and said.

"This alchemy doesn't require much physical strength, but it is a very huge project for spiritual power, just now you see that I actually demonstrated it for a few seconds, but I have already exhausted all my spiritual power. Mu Feng sat down with Luo Tian's support and explained to Luo Tian.

"I'll just say, how could Uncle Mu Feng be so tired like this for so long, it turns out that his mental power is consumed a lot!" Luo Tian said with a clear expression.

"How did you see the 'Firmament Fire Control Technique' I just used, do you have any thoughts, tell me." Mu Feng said to Luo Tian.

Luo Tianzhi said that Mu Feng wanted to test him, so he recalled that Mu Feng's performance just now still said his thoughts.

"I think Uncle Mu Feng's speed just now is too fast, and he is too anxious, and the most important thing is that Uncle Mu Feng did not control the fire, of course, this should be related to your mental power, I think if I am Uncle Mu Feng, since my physical strength is not good, then why should I control the entire flame, I can completely peel off some flames and control them alone, so that I am not tired, and the effect will be better." ”

"Very good, Tian'er, you said it very well, but you are thinking about it, what did I control the fire so much just now?" Mu Feng praised Luo Tian.

"I know that Uncle Mu Feng should want the flames to form a Dan furnace, and then directly refine the Dan, but because of the lack of spiritual power, or the lack of mastery of the 'Firmament Sky Fire Technique', it caused Uncle Mu Feng's furnace to disperse before it was formed. ”

In fact, Luo Tian felt in his heart that Uncle Mu Feng's mastery of the 'fire control method' was not thorough enough, because although he didn't know alchemy yet.

But he still thinks that since it is alchemy, then the most important thing in alchemy should be refining, you haven't practiced yet, and you are already tired.

This should not only be the reason for the lack of mental power, although the Firmament Burning Ding Technique is difficult, but after all, it is used for alchemy, and I think it is the most difficult when I practice.

After Luo Tian finished speaking, he found that Mu Feng looked at him blankly, thinking that he was talking about him, Mu Feng was not satisfied, after all, he was just a person who had not yet started to learn alchemy, how could he be qualified to say this.

"Uncle Mufeng, don't blame Luo Tian, Luo Tian is talking nonsense, don't blame Luo Tian. Luo Tian looked at Mu Feng and immediately explained.

"No, no, I don't blame you, I'm surprised, I didn't expect that the pill I had been refining all my life would be told by you, a kid who has not yet made alchemy, and it's all right, Tian'er, I believe you will be able to learn this set of fire control techniques, I'll take a break, I'll show you the real alchemy, and then you can start learning to refine the pill." Mu Feng looked at it and said with a sudden smile.

"Good!"
