With the slow passage of time, alchemy has reached a critical moment. At this time, Huo Lao's expression was very nervous, when he practiced this elixir before, he fell short at this moment. So he had to get nervous, and he was afraid that this time, as before, would not end up as he wanted.

The alchemy furnace, which was originally pitch black, had changed color at this moment. From a pitch-black alchemy furnace to a fiery alchemy furnace.

Lin Feng and the others looked at the alchemy furnace in surprise, and they couldn't help but panic in their hearts. Looking at the fiery alchemy furnace, as if it was about to explode at this time, they couldn't help but retreat. They wanted to get out of here immediately, but when they saw that the fire was around, they forced themselves to stay.

After another moment

Huo Lao was already a big man, and he was carefully trying to control it at the moment. But at this moment, the alchemy furnace has become more and more unstable. I saw that the Dan furnace shook slightly, and there were cracks on the furnace wall.

Lin Feng and the others looked at the situation at this moment, and it became more and more unstable, so they didn't dare to stay any longer, so they slowly evacuated. Huo Lao was concentrating on alchemy at the moment, and he didn't know about Lin Feng's evacuation at all.

Click!

A slight sound came from the Dan furnace, and although the sound was relatively small, it was still heard by the people in the stone chamber.

Huo Lao couldn't help but chuckle in his heart when he heard this voice coming from the Dan furnace, and at the same time secretly exclaimed in his heart: "Oh no!

Lin Feng and the others hadn't retreated far before, when they suddenly heard a voice, and their hearts instantly burst out. So they didn't care about anything else, and they ran wildly.

Boom!......

Yes!

Yes!

Yes!

Yes!

Lin Feng and the others had just run a few meters away when the alchemy furnace exploded involuntarily. As soon as the alchemy furnace exploded, the ground simply shook, and the breath in the stone chamber suddenly became chaotic. And when the alchemy furnace exploded, in addition to the rumbling explosion, four tragic cries came out.

Although Lin Feng and the others evacuated first, their movements were still too slow. And Huo Lao wanted to escape, but he couldn't escape.

Burst!

"Phew, bah, I didn't expect this bomb to be so powerful. Alas, this time it failed. ”

Huo Lao lay on the ground and spit out the dirt in his mouth vigorously, and then sighed deeply.

Hey!

"No wonder the old man didn't escape this time, it turned out to be these three stinky boys!

Huo Lao looked at Lin Feng and the others under him, so he muttered sadly.

In fact, when he was refining the pill in the past, if he found out that he was going to blow up the pill, he would not hesitate to fly out of the stone room. This time, as usual, he immediately chose to fly away when he found something wrong. But he never expected that Lin Feng and the others would actually block his way. And the bombing of Dan happened in an instant, so he was not spared.

After a long while, Lin Feng and the others slowly woke up.

"Hiss, it hurts!" Lin Feng let out a miserable scream and broke open his eyes, and then he looked at Huo Lao and exclaimed in surprise, "Ahh

At this time, Huo Lao's clothes were in tatters, and he stood beside Lin Feng and them. With messy hair, he stared at them motionlessly, as if he was alone there in a daze.

"Master, how are you doing?

"Master, you can't always blow up the Dan furnace, do you?"

Lin Fan and Lin Lei also woke up at this moment, and they endured the pain and immediately asked Huo Lao.

Belch!

Huo Lao was stunned by Lin Feng's question, and then the corners of his mouth twitched fiercely, and at the same time took out a bottle of elixir, threw it to Lin Feng and said, "There is a bottle of healing elixir here, you can take it to heal yourself!" After speaking, Huo Lao quickly left the stone room.

Belch!

"Big brother, what's the matter, Master?" Lin Fan couldn't help but ask in astonishment as he watched Huo Lao leave suddenly.

"How do I know!" Lin Feng glanced at him angrily, and then said to Lin Fan and them: "What are you still thinking about here! After speaking, Lin Feng took the lead in leaving.

"Oh! it hurts!"

"yes! We're really unlucky this time!"

Lin Fan and Lin Lei were walking out, and their mouths were still full of broken thoughts.

After Lin Feng returned to the room, he didn't do anything else, and immediately began to meditate and heal.

And this time, it took them three days to heal. Although they suffered a lot of injuries, they were also relatively lucky. After all, behind them at that time, there was a fire elder who gave them a beating, so that their injuries were much lighter. If it weren't for the fire elder to resist him, at least they would have to use it for a few days.

Three days later

Elder Huo was already refreshed, and he was sitting on his throne at this time. And Lin Feng and the others were sitting below him, listening carefully to Huo Lao's speech.

At this time, I only heard Huo Lao say to Lin Feng and them: "Don't worry now, there is a spiritual refining method here for the teacher, and you can cultivate the true qi first." As long as you have true qi in your body, and then you are familiar with the medicinal properties of herbs, you can teach you alchemy, do you know?"

"But, Master, we already have true qi in our bodies! You can start teaching us alchemy when you are old!"

Lin Feng listened to Huo Lao's words, and he immediately said eagerly.

In fact, Lin Feng also knew deeply that he had the benefits of the elixir, so he would speak eagerly. Bigu Dan solves the problem of eating, healing pills solve the problem of injuries, and some pills can solve the problem of cultivation.

The various benefits of the pill had to make them red-eyed. So after they recovered from their injuries, they immediately found Huo Lao after discussing with each other and asked Huo Lao to teach them alchemy. Although alchemy is very dangerous, they don't care so much.

"What! you actually have true qi in your body, why don't you know it!" said Huo Lao in surprise.

In fact, Huo Lao had not paid attention to Lin Feng and them, after all, when Lin Feng and them tested before, they didn't have any true qi in their bodies. Otherwise, with his cultivation, it would not be a simple matter.

As Huo Lao spoke, he immediately sensed Lin Feng and them with his divine sense. And Lin Feng and the others were just about to speak, when they suddenly felt a majestic divine sense swept over their bodies, so they immediately closed their mouths.

Well!

"Yes, you do have true qi in your body, and you have reached the middle and late stages of spirit refining, so you can learn the art of alchemy. ”

After Huo Lao looked at it slightly, he was suddenly shocked. Then he nodded slightly, and said to Lin Feng and them with satisfaction.

"Hehe! Master, will we start learning alchemy now?"

Lin Feng listened to Huo Lao's words, and immediately smiled happily, and at the same time asked Huo Lao urgently.

Huo Lao grabbed his beard and muttered for a while, and then said to Lin Feng and them, "Okay! After saying that, Huo Lao disappeared into the main hall in an instant.

After Lin Feng and the others were slightly stunned, they immediately entered the stone room with a happy face.

In fact, Lin Feng and the others didn't know that Huo Lao was happier than them at the moment. This was mainly brought to him by Lin Feng and them, and the reason for this was simply very simple. First: It's because Lin Feng and they already have true qi in their bodies at the moment. Second: That is Lin Feng's passion for alchemy.

Those disciples who used to follow Huo Lao were either as timid as a mouse, or they were inferior in all aspects. And Lin Feng is in a different situation, not only is he bold and enthusiastic, but he is also excellent in all aspects. This did not make him overjoyed, and he acted quickly with joy.

Not long after Lin Feng and the others arrived in the stone room, Huo Lao appeared in the stone room. After Huo Lao came to the stone room, he gave each of them an alchemy furnace, and then began to explain the art of alchemy to them.

Huo Lao was ready to let them refine the Bigu Dan, which was an easy pill to refine, and it was only a first-class pill, and the requirements for alchemy were not high. Huo Lao prepared a hundred herbs for them to practice first. After all, if you want to become an alchemist, you have to feed it with countless herbs.
