Nie Tian smiled and said, "A predatory method? That's a very apt description."

Lu Chen said: "It's not as exaggerated as you think, because the aura here is very pure, so the refining speed is much faster than usual. In general, to achieve this effect, even if the concentration of aura is the same, it will take three or four hours to do it. arrive."

"Three or four hours?" Liao Tongming's green eyes flickered.

Duan Xing's face was also a little ugly.

So much spiritual energy just now, even under normal circumstances, it would take others at least a day and a night to completely digest it. That is already considered a genius, and his talent is outstanding, but Lu Chen still looks like a normal person, as if he did it. This level is normal.

This made Liao Tongming, the master of Tiandaomen who always regarded himself very high, simply couldn't bear such a blow.

Everyone who can cultivate to the Primordial Spirit Realm is a genius among geniuses, but Liao Tongming found that compared with Lu Chen, he was simply a mediocre person. Not to mention Lu Chen, even Nie Tianli next to Lu Chen felt unfathomable.

In the past, Liao Tongming always felt that as the suzerain of Tiandaomen, his status was detached, and he always had a psychological advantage in front of a young man like Lu Chen. At that time, he still didn't understand why a master in the primordial spirit realm like Nie Tianli would actually be against Lu Chen. Chen is like an old friend of the same generation, and now he knows that Lu Chen really has this qualification.

Lu Chen smiled and said, "It took so long for everyone to wait, so let's go to the second floor immediately."

Everyone nodded yes.

"Old Nie, have you figured out what's going on here?" Lu Chen asked.

He had been meditating for so long just now, and it was impossible for Mr. Nie Tianli to be idle.

"I used my divine sense to search the neighborhood just now, but I didn't see anything unusual. There were no monsters, no restrictions, and no elixir. It seemed like there was nothing." Nie Tianli said.

"Nothing?" Lu Chen was a little strange and asked Liao Tongming, "What do you think of Sect Master Liao?"

Liao Tongming said: "I don't know, I just saw the map of the Great Desolate Ancient Realm before, and I don't know what is here."

"Oh?" Lu Chen was a little confused, "The situation here is really weird, is there any danger?"

Nie Tianli said: "Don't worry, I have searched many times with my spiritual sense just now, but I can only sense that Ding Yun and his party are in the north direction, which is far away from us. "

Lu Chen nodded, this situation was not what he expected.

After all, the spiritual energy here is mellow, even for the experts of the cave, it is a rare treasure. If you can’t find any treasure, you must make good use of the spiritual energy here.

"Don't worry about it so much, go to the second floor to see." Lu Chen said.

Everyone continued to move forward. There were no accidents along the way. Soon, the four of them found that there was a seal restriction in front of them. Everyone knew at a glance that this should be the entrance to the second floor.

"How to crack the ban, forcibly crack it?" Lu Chen saw that the seal ban was very complicated, and he didn't know what the consequences of brute force cracking would be.

Liao Tongming said: "No need, you can directly unlock the seal using Jiutian Xuangong."

"Can I also use Jiutian Xuangong to lift the seal here?" Duan Xing was a little curious.

"You only need the Nine Heavens Profound Art. You don't need the Big Dipper Talisman. Even if you have the Big Dipper Talisman, when you cracked the seal outside, the power inside was exhausted, and it is impossible to restore it in a short time. Here we only need to use the Nine Heavens Profound Art. Just lift the seal." Compared to everyone else, Liao Tongming was quite familiar with the situation here.

It seems that Tiandaomen and the Yuanshimen of that year are indeed deeply related, and the entire ancient realm can only use Jiutian Xuangong to break the seal.

Liao Tongming took the initiative to step forward, the wolf claws went forward, and a pure and majestic force was integrated into the ban. Liao Tongming's strength is not enough now, so it is really hard to break the seal. It took a while to break it. After opening the seal and the seal was lifted, he had to stop and rest for a while.

Through the unlocked seal, Lu Chen felt the spiritual power coming from the second layer of space, which was purer.

"I don't know if there is any danger here. I heard that there were some powerful guardian spirit beasts in Yuanshimen." Duan Xing said suddenly.

Nie Tianli said, "No matter what guardian spirit beasts are, go and see first."

With the strength of his Primordial Spirit Realm, there are very few monsters in the world that can threaten him, and everyone is not worried and walks into the second layer of space one by one.

The environment on the second floor seems to be no different from the first time. It is still monotonous gray, but the temperature is very high. When everyone walks in, it is like entering a large furnace.

The first time the temperature in the space was icy and cold, and the second time it was like walking into a furnace. Everyone experienced this contrast, and some of them couldn't react.

Of course, for those who have cultivated, even if they are really in the furnace, it is not a big problem, and this temperature is not enough to cause much impact.

"Why is it so hot in here? Could it be that there is a volcano here?" Nie Tianli asked.

Liao Tongming also shook his head and said he didn't know.

Everyone walked forward, only to feel that the air was getting hotter and hotter. At this moment, Lu Chen suddenly noticed a few herbs in the distance.

"Earth Fire Lingzhi, such a pure fire spirit." Lu Chen walked to the herbs.

Judging from the fire spirit power emitted by several herbs on the ground, these herbs are all fire herbs with strong medicinal properties.

But it is also true that the temperature here is so high that ordinary spiritual herbs will definitely not be able to survive, because the temperature requirements of general spiritual medicines are very strict, and not all environments can grow.

"There is also here." Duan Xing also said.

Along the way, Lu Chen discovered six or seven Ganoderma lucidum plants.

Nie Tian said with a stern smile, "Earthfire Ganoderma lucidum is not a rare medicine. There are some around the crater. What's strange? It looks like you treat him as a treasure."

Duan Xing hurriedly said, "Although this is an ordinary Earth Fire Ganoderma lucidum, it has grown for two thousand years and has absorbed a huge amount of Fire Spiritual Power and Immortal Spiritual Power. It is not comparable to ordinary herbal medicines."

"Not only is it not comparable to ordinary herbal medicines, it is simply impossible to find. The effect of this Earth Fire Ganoderma lucidum is no less than that of Fire Dragon Flower." Lu Chen said.

Nie Tian said sternly, "Fire Dragon Flower? Is it a natural treasure that people who practice fire-type exercises need? It's a pity that the four of us have practiced fire-type exercises, so it seems that this thing is only useful to you.

"You're wrong, it's useless to me, my fire-type practice has already been completed, even if refining these Earth Fire Ganoderma lucidum, the improvement effect is not large, but it can be used to refine a kind of treatment for the nine yin cold spirits. body medicine." Lu Chen smiled.

Duan Xing was overjoyed when he heard the words: "Brother Lu, are you saying that this Earthfire Ganoderma lucidum can cure the young lady's disease?"

"Of course, after I get the melting pot of heaven and earth, I will help Miss Song refine the elixir. With so many earth fire ganoderma lucidum, I am at least 90% sure that I can cure the body of the nine yin cold spirit." Lu Chen smiled.

Duan Xing looked excited and said, "The old man will thank Brother Lu for the young lady."

Nie Tianli hurriedly asked what was going on, Duan Xing explained the matter, Nie Tianli listened, and asked in surprise, "Lu Chen, do you still know how to refine this level of medicine?"

"As long as the furnace of heaven and earth is found, there will be no problem." Lu Chen said.

"...Is there anything else you can't do?" Nie Tianli asked in a strange tone.

Lu Chen laughed: "I don't know a lot of things, but as long as I learn, I believe that even if I can't, it won't take long."

Nie Tianli could only helplessly shake his head. Compared to Lu Chen, he felt that he was far worse.

Nie Tianli has always thought that he is a rare genius who is also proficient in magic and martial arts, and is proficient in formation techniques. However, compared with Lu Chen, it turns out that he is nothing. He seems to know Lu Chen, but he is not as good as Lu Chen. .

…

The four of them collected Earth Fire Ganoderma lucidum, and it didn’t take long for them to collect more than 20 plants. Although Earth Fire Ganoderma lucidum was precious, but they didn’t need it, they simply gave it to Lu Chen. Even if Lu Chen failed to refine the medicine pill, it would be impossible. Dozens of consecutive failures can guarantee the success of the medicinal pill refining.

At this moment, everyone noticed that there was a place in front of them with a slight white light. They walked over and found a white stone tablet.

"What is this stone tablet?" Nie Tianli asked, and everyone looked at Liao Tongming.

Liao Tongming shook his head and said, "I don't know either."

Nie Tianli said again, "Boy Lu, you don't know this stone tablet? What are the characters on it, do you know them?"

There are indeed some strange words on the stone tablet, but Lu Chen doesn't know that he doesn't know, he has never even seen it before, so he doesn't know what's going on.

Nie Tianli's experience is also rich, but he doesn't know what the word is.

The four of them looked at each other and said they had not seen each other.

Lu Chen reached out and touched the stone tablet. The stone tablet had a gentle and peaceful power, and Lu Chen felt a faint fairy spirit emanating from it.

Feeling this, Lu Chen looked strange.

Nie Tianli asked, "Boy, is there anything wrong with this stone tablet?"

"Look at it yourself." Lu Chen said, "What the hell?" Nie Tianli stepped forward and used his spiritual sense to inspect the stone tablet, but the stone tablet repelled all mental perceptions. No matter how strong Nie Tianli's mental power was, it would have no effect at all. Explore with touch.

"What's going on here?" Nie Tianli said, "Is this stele able to generate celestial power?"

Duan Xing and Liao Tongming were shocked when they heard it.

"Producing fairy power? Is there such a treasure in the world?" Duan Xing's expression changed slightly.

Lu Chen had previously sensed that the stone tablet seemed to be generating spiritual power, but the speed was extremely slow.

"The speed is very slow. At this speed, even at the end of the year, it won't generate much immortal spirit power," Nie Tianli said.

"One year naturally cannot have much effect, but this ancient space has been around for 2,000 years, and 2,000 years is enough to generate incomparably abundant immortal energy," Lu Chen said.

Everyone nodded in agreement.

They finally understood how the immortal spirit power of this ancient space was generated, and it turned out to be because of this stone tablet.

But how could a stele generate endless immortal power?
