Back at the hotel where he stayed before, Liu Chengfeng opened a room for Guan Shangfei and the two of them alone, before locking himself in the room, and took out the imperial green that had just been opened and played with it carefully.

The imperial green with aura looks pleasing to the eye, especially the green color, which is even more refreshing. However, Liu Chengfeng's attention is obviously not on the jade itself, but on the aura contained in the jadeite.

In the final analysis, jadeite is only a kind of stone, if it is only good-looking, the spirit stone in his hand is much better than jadeite, whether it is from the shape, color, light transmittance, can completely explode jadeite.

Therefore, Liu Chengfeng just played with it for a while, and then held the jade and immersed himself in cultivation. The aura contained in the jade is very pure, which is conducive to absorption, unlike the spirit stone, which takes a lot of energy to refine the impurities.

Liu Chengfeng carried the "Changchun Sutra", like a long whale absorbing water, the aura in the jade slowly incorporated into the dantian, slowly, his dantian gradually filled, and I don't know how long it took?

At this time, his cultivation had already recovered to its peak and he had become a monk in the late stage of the second layer of Qi training.

Looking at the time, it was already more than seven o'clock in the evening, and it had been four hours before going up the mountain.

Looking at the absorbed jadeite in his hand, it looks intact and does not seem to have changed. However, the careful Liu Chengfeng still noticed that the green color was a little dull, but it did not affect its value.

Putting away the jade, Liu Chengfeng stretched and walked out of the door with a smile on his face.

Next to it was Guan Shangfei's room, after Liu Chengfeng went out, he knocked on the door next door directly, and asked loudly: "Guan Guan, have you woken up......?"

After knocking, Liu Chengfeng did the same and knocked on Mulan's door. After the two opened the door, Liu Chengfeng supported Mulan and walked out of the hotel together.

Transportation on the volcano is extremely inconvenient, and the catering industry on the mountain is mostly pasta, waxed goods, and dry goods, and vegetables are relatively rare. Naturally, the trio opted for pasta.

For those who are used to eating rice, it is also good to change the taste once in a while. When the three bowls of noodles were served, Guan Fei asked while eating: "It's so late, the kid surnamed Nie shouldn't come up, right?"

It's already eight o'clock now, and the sky has already darkened, Liu Chengfeng doesn't believe that Nie Wenyue will come to attack at night. Besides, a second ancestor like this who has eyes above the top, even if he wants to humiliate people, he is looking for a place where there are many people.

So he smiled and said: "You can rest assured, when he comes up, it will be almost ten o'clock." Even if he knew we were in the mountains, he would change the time......"

After Liu Chengfeng said this, Guan Shangfei immediately relieved himself.

After eating, Guan Shangfei and Mulan went back to the room to rest again. Liu Chengfeng took advantage of the night to take the alchemy materials and walked in the direction of the hot spring.

Around the hot springs, there is only a faint light, and people can barely see the water surface of the foggy rising. Liu Chengfeng stood at the bottom of the hot spring, holding his chin but making a difficulty.

The visibility is so low, even if there is a fire under the hot spring, it is in vain! If you can't see anything, how can you make alchemy? After pondering for a while, Liu Chengfeng finally decided to go down to explore the road first to see if there was an active volcano at the bottom of the hot spring?

Thinking of this, Liu Chengfeng "fluttered", plunged into the misty hot spring, and swam to the bottom of the hot spring.

At the beginning, a scorching breath came to his face, but before this hot breath touched Liu Chengfeng's body, the water beads played a miraculous effect. It seems that there is an invisible energy that automatically separates the hot spring water, so that the water can't get close to Liu Chengfeng's body at all.

It's like a drop of oil floating on the surface of the water, so that the two can't merge at all.

This time, Liu Chengfeng finally put his mind at ease, and then he slowly adjusted his position and carefully sank to the bottom of the hot spring. I don't know how long it took? When the visibility around him was getting lower and lower, and it was pitch black, he couldn't even see his five fingers clearly, Liu Chengfeng suddenly had an idea.

There won't be a monster at the bottom of the hot spring, right? What if you get eaten?

After a few more minutes, Liu Chengfeng estimated that he had dived two or three hundred meters, but he still found nothing. Just when he was a little impatient and had the idea of retreating, there was a faint glow from the bottom of the hot spring.

Liu Chengfeng's spirit was shocked, and he couldn't wait to sink to the place where the light emanated.

A few minutes later, the light suddenly burst into flames, and the gushing magma also met Liu Chengfeng's eyes. Seeing this scene, Liu Chengfeng was immediately overjoyed. It seems that the noodle shop owner's guess is correct, and there is indeed an active volcano at the bottom of this hot spring.

Now, Liu Chengfeng is ready for everything, only the east wind is owed. When you see the surging magma constantly tumbling, it proves that the east wind is also there. Liu Chengfeng, who was overjoyed, hurriedly rushed towards the fiery red magma.

The magma that can melt even steel is insignificant in Liu Chengfeng's eyes. With a fire bead for self-defense, he quickly merged into the magma and became one with the magma.

Due to the high temperature of the magma, the water on it turned into steam as soon as it sank. So between the two, a vacuum was formed.

Liu Chengfeng stopped in the vacuum zone and began to look at the surrounding environment.

On the surface, it is a very stable active volcano, and although the magma is choppy, there is no sign of eruption for the time being. The crater is not too big, only half the size of a basketball court. Around the volcano, there are hard rocks everywhere. These rocks have been forged by volcanoes for many years, and the hardness is probably not lower than that of ordinary steel, right?

In addition, this active volcano also contains a large amount of fire element power, and from this point of view alone, this place is suitable for alchemy.

After nodding with satisfaction, Liu Chengfeng began to count the materials for alchemy, and at the same time spent eight spirit stones to buy a lowest-grade Dan furnace from the mall, and then took a deep breath and prepared for alchemy.

For the first time in alchemy, Liu Chengfeng was still a little nervous in his heart.

However, when he recalled the steps of alchemy, his heart slowly calmed down again. At this time, he took another deep breath, and then suddenly pushed the Dan furnace out, and under the influence of external forces, the Dan furnace flew towards the crater and spun dripping.

Seeing this scene, Liu Chengfeng hurriedly played a pill recipe and attached it to the Dan furnace, as if he had been immobilized, and the rapidly rotating Dan furnace stabilized.

Liu Chengfeng's first step was perfect, which made him feel a little happy in his heart. However, he also knows that alchemy has just begun, and whether he can produce Dan next depends on his on-the-spot performance.

So he stabilized his mind and tried to calm himself, and it took a long time to take out the hundred-year-old ginseng, cut a small piece with the knife he carried with him, and threw it into the Dan furnace.

A ginseng can not only be refined once, probably due to the rate of becoming a pill, immortal cultivators will divide the precious medicinal materials into several parts. In this way, not only does it greatly increase the rate of success, but also reduces the waste caused by failure. Over time, this habit was preserved.

When a small piece of ginseng was put into the Dan furnace, Liu Chengfeng successively put two flavors of auxiliary medicine into it, and then stared intently at the changes in the Dan furnace.

Sneer-

A slight sound came from the Dan furnace, and the medicinal materials in the Dan furnace were quickly removed from impurities, turning into a round bead tumbling in the Dan furnace.

Seeing this scene, Liu Chengfeng was trying to take another pill trick into it, so that the medicinal herbs could absorb the aura contained in the air. But suddenly, two streaks of green smoke rose from the Dan furnace, and then the round bead turned into a charred ......
