In other places, Ning Chuan would never take the initiative to take out the martial arts so much, but now that he is in the Demon King's Mansion, he will have to take it out sooner or later, so he might as well take it out generously like the Mogu Demon King, and he won't have to be so embarrassed that the Demon King takes the initiative to speak.

"Useful, so useful!"

The Fire Demon King's eyes were full of surprise, and even his usual simple appearance disappeared, happy like a child.

"It's good to be useful, I'm still worried that these things are too chicken, and the two of you can't look down on them!"

Ning Chuan scratched his head embarrassedly and said softly.

In fact, in the outside world, the martial arts he took out were not precious at all, and compared to the treasure land here, it was simply a cow's hair.

It's just that there has never been martial arts here, and it has a definite enlightening effect on their cultivation, which is just precious.

"No, these martial arts, we have to study them carefully, I believe that soon, we will be able to create the most suitable martial arts for ourselves!"

Compared with the demon cultivators outside, Mo Gu and the Fire Demon King both knew that what suited them was the best, so these martial arts were shared, and there was nothing for them.

"That...... The two seniors, Ning Chuan had a few questions, and he didn't know whether to say it or not. ”

Seeing that it was almost the same, Ning Chuan also mustered up the courage to speak, after all, he asked the demon king to find him, just to get the treasure that Blue Ji Huokou said.

"Say, as long as we can do it, we can try to satisfy you!"

Mo Gu was obviously in a good mood, and agreed without even thinking about it.

"I want to know, what kind of place is this, why do you have such a strong spiritual power of heaven and earth, and why you have not even heard of martial arts, but you can cultivate to such a powerful point. ”

The questions that had already been suppressed for a long time appeared in Ning Chuan's mind, since he had already spoken, Ning Chuan had no intention of hiding, he said it in a tone, and looked at the two demon kings nervously.

These problems, especially the one involving the spiritual power of heaven and earth, can be said to be the secret of this heaven and earth, and if the two demon kings are unhappy, it is very likely that they will be killed here.

"Little friend Ningchuan, don't be so nervous, we won't do anything to you!"

Hehe, Mo Gu took the lead in speaking, paused, and continued: "We don't know what this place was originally called, but after our four demon kings stood on all fours, we helped him come up with a name, and we called this place Beiyoudongtian!"

"Even you don't know what it's called?"

Ning Chuan was stunned, this is really incredible, but this name is also very appropriate, after all, this place is isolated from the outside world, and it has its own world, and it is not too much to call it a cave.

"Here, it's been around for a long time!"

The Flame Demon King also said something in a deep voice, but Ning Chuan heard the taste.

They all said something inconsequential, but they didn't say a word about why the spiritual power here was so strong, obviously they didn't want to tell Ning Chuan.

You must know that Ning Chuan came here to get the treasure here, and now they don't tell Ning Chuan any news, which makes Ning Chuan embarrassed, if you say it directly, Ning Chuan is still a little worried that they will be directly wiped out.

After all, whether it was the Mogu Demon King or the Fire Demon King, for Ning Chuan, they were both unattainable powerhouses.

"That's it, and tell you!"

Seeing Ning Chuan's expression, Mo Gu didn't know what Ning Chuan was thinking, and after a long sigh, he continued: "Originally, this was a medicine garden, according to rumors, this medicine garden was founded by a person named Shennong's family!"

"What!?Shennong's!?"

After hearing this, Ning Chuan stood up and really lost his temper.

Shennong's is Shennong's Emperor, before he achieved the throne, the world called him Shennong's, so the title of Shennong's has been a very long time.

"yes, what's wrong?"

For Ning Chuan's surprise, the Mogu Demon King was even more surprised.

He didn't know how powerful the Shennong clan was, but he just knew that there was such a person who created such a place.

"No, nothing!"

Forcibly retracting his mind, Ning Chuan asked the Mogu Demon King to continue, and Ning Chuan slowly understood this place.

This is indeed a nameless place, and it is indeed a medicine garden, but after countless years of changes, many elixirs have withered, leaving only a few elixirs.

Of course, after countless years of nurturing the elixir, the spiritual power of this heaven and earth has gradually become richer, and the most precious thing in this world is an ancient tree.

Legend has it that the ancient tree, since the appearance of this heaven and earth, has been born here, and the spiritual power of those withered elixirs has all been absorbed by him, and then released out, all over every corner of the surrounding area, providing enough spiritual power for demon cultivators.

"How powerful is the spiritual power of this ancient tree!"

After listening to this, Ning Chuan couldn't help but gasp, how much heaven and earth spiritual power had been absorbed by the ancient trees that had grown over countless years in order to convey such powerful spiritual power to such a large area.

Moreover, in this area, those spiritual powers were so strong that they were so strong that they were in the hot springs of Huahua Waterfall......

"I don't know, can I go see this ancient tree?"

Looking at the two demon kings with some apprehension, Ning Chuan asked softly.

Before he came, he definitely had illusions, but after hearing this, Ning Chuan was a little uneasy, because of the preciousness of the ancient tree, he could even think of it on his toes, if it was not good, it would affect the entire world here.

"This ...... I'm afraid it's difficult!"

Just as Ning Chuan thought in his heart, after Ning Chuan said what he requested, the Mogu Demon King was stunned and said in embarrassment.

Sighing, Ning Chuan's heart already had a feeling, although his heart was a little regretful, but he quickly adjusted, and hurriedly said that it didn't matter.

What if it has a relationship, he can't rush up and tear the two demon kings to slag.

"No, Ning Chuan, I must go and have a look, otherwise, I will work hard to bring you in, but my efforts will be in vain!"

Blue Ji Huo's dissatisfied voice came, the voice was very small, obviously very weak, but Ning Chuan pretended not to hear it, and continued to talk with the two demon kings.

That ancient tree, how to see it, otherwise, even he himself will not give up, let alone the blue Ji Huo.

"Ningchuan Xiaoyou, you can cultivate here, but I advise you, don't try to get close to the ancient tree, the ancient tree's devouring ability is particularly strong, if you are not careful, it is very likely that even you will be devoured, even our demon kings, we dare not approach easily!"

Although Ning Chuan covered it up well, the Mogu Demon King still seemed to see something, and said something pointedly.

"Thank you for the Demon King's reminder!"

Nodding, Ning Chuan said softly, if you want to go, of course you go secretly, you can't let them know, anyway, in the conversation just now, Ning Chuan already knew the approximate location of the ancient tree.

After talking for a while, the Flame Bull Demon took some martial arts and didn't stay anymore and left the cave, while Ning Chuan and the others stayed in the cave.

The life of the demon cultivator is very simple, the sky is the bed, the ground is the quilt, anyway, here, there is no need to worry about the trouble of someone coming to him.

That night, the Mogu Demon King comprehended all the martial arts, and when he waved it in this world.

And Ning Chuan also gave up sleeping, and quietly watched the demon king in mid-air.

This kind of strong person, between raising his hands and feet, is dancing the avenue of heaven and earth, and the momentum it exudes is faintly much stronger than that released by Qianqian, and observing the cultivation of such a strong person also has certain benefits for Ning Chuan.

The following days became ordinary, Ning Chuan would observe the cultivation of the Mo Gu Demon King from time to time, and then get an understanding, he would directly sit on the ground and cultivate, and when he encountered a problem that he didn't understand, he would also humbly ask the Mo Gu Demon King for advice.

Ning Chuan is improving, and the Mogu Demon King is also improving, and after about ten days, he has studied all the martial arts that Ning Chuan gave him, and created his own martial arts, which is amazingly powerful.

According to Ning Chuan's opinion, the martial arts created by the Mogu Demon King were at least the martial arts of the heaven-level lower grade, which was really amazing.

However, sometimes, the Mogu Demon King will also be ashamed to ask, and discuss things about martial arts with Ning Chuan, although the two are not in the same realm, but they have unique insights into martial arts, and they are often able to draw inferences.

"Ning Chuan, you are really a genius!"

After every exchange, the Mogu Demon King would be full of praise for Ning Chuan, not only because of martial arts, but in terms of cultivation, Ning Chuan also had a certain knowledge, and he didn't look like a cultivator in the late stage of the Guiyuan Realm at all.

And whenever this happens, Ning Chuan will be very modest, but in fact, his heart is a little happy, after all, not everyone can be praised by the demon king.

Soon, the Flame Demon King also received the news, and the three of them came to the cave mansion of the Mogu Demon King in the first two days, inviting Ning Chuan to yearn for his cave mansion and discuss the matter of martial arts.

For this kind of thing, Ning Chuan naturally won't refuse, so it can also make him more knowledgeable, why not?

As the saying goes, some people are happy and some people are worried, the strength of the Mogu Demon King and the Fire Demon King is growing day by day, but the other two demon kings are still standing still, which is not a good thing for their status.

"Mouse, if we don't act, we won't have a chance!"

The white-haired demon king and the rat king gathered, their voices were cold, and their eyes were shining.

Both of them knew that if they lost the position of the Demon King, their status would be lost, and if they lost the realm, their cultivation aura would be greatly reduced, and if they wanted to be in the same position as the Fire Demon King and the Mogu Demon King again, it would be even more difficult.

"Don't worry, as long as I make a move, that kid will naturally not be able to run out of my palm!"

The Rat King patted his chest and said confidently with a face.

As the Rat King, he has extremely profound attainments in the Hidden Dao, and with such a huge realm gap between him and Ning Chuan, he doesn't think that Ning Chuan can escape from his hands.

"Don't kill him, kill him, and we'll really have no hope!"

After the white-haired old man said a word, he disappeared into the void and disappeared without a trace, and after the Rat King glanced at the Flame Demon King's cave, he also disappeared.

To be strong, everyone should be strong, after all, their four demon kings have controlled this world for thousands of years, and they are not allowed to break the balance, so the two rat kings will make up their minds to get the martial arts of Ning Chuan's hand.
