Although it is good to have another cave, and the strength of the four demon kings is also very strong, they are not the most powerful existence in this world.

This place provides them with the best cultivation environment, and similarly, there are also their limitations here, because after reaching this step, they have no stronger people to surpass.

This question was not the first time Ning Chuan had asked the Flame Demon King, but every time the Flame Demon King's answer disappointed Ning Chuan, and this time was no exception.

"I always believe that only under the raging storm, the strong who grows up can become the strong, and the flowers in the greenhouse are always easy to wither!"

Looking up at the stars looming in the sky, Ning Chuan said slowly.

Along the way, the torture he has experienced is not less, but no matter what, he has persevered, and his strength is much stronger than that of ordinary cultivators, it is this step by step strength, constantly strengthening his heart, he will not stop a step, slowly walk.

"Do you think this is a greenhouse? The killings here are sometimes brutal as well!"

The Fire Demon King said in a deep voice, he hadn't forgotten how he climbed up step by step in the first place.

His cultivation talent and qualifications are not as good as the other three demon kings, and he has been able to get to this point, and he has spent his essence and blood, and the demon cultivators of his generation who have killed, I don't know how much.

It is precisely because of his solid foundation and incomparably strong body that he has a certain status among the four demon kings.

"No, I mean, now that you have cultivated to the extreme in the other caves, and no one is your opponent anymore, why don't you let out the demon king and go out to the outside world to find a stronger opponent?"

Ning Chuan knew that the Flame Demon King had misunderstood what he meant, and hurriedly explained, but this sentence really moved the Flame Demon King, the light in his eyes flashed, and then asked, "In the outside world, there are people who are more powerful than me?"

"Yes, and there are many of them who are still my enemies, although I have never seen them, but I am sure that their strength is definitely in the same realm as yours!"

Thinking of the Luo family, Ning Chuan nodded firmly, and a trace of hatred overflowed from his words.

If he wants to win over the Flame Demon King, in fact, Ning Chuan also has a little private message, after all, whether it is the Luo family or those unborn hidden families, there is a certain threat to Ning Chuan, and with his current strength, there is no way to compete with it at all.

And before he was strong against those families, Ning Chuan naturally had to win over some strong people, otherwise when the war started, how could he shout for those hidden families?

"I can't think of it...... There are such powerful people!"

With a sigh, the Fire Demon King pondered for a while, and then said: "I promise you, when your things are done, I will leave here with you, go to the outside world to see, and leave this unique cave to the three demon kings to fight for!"

Before agreeing, Ning Chuan had already explained very obscuribly what he meant to win over the Flame Demon King, but after hearing this, the Flame Demon King did not hesitate at all, but agreed in one bite, which showed his attitude towards Ning Chuan!

After hearing this, Ning Chuan glanced at the Flame Demon King gratefully, but he didn't say anything, this friendship, he had already deeply remembered it in his mind, if there was a chance to repay it, he would definitely repay it!

In the following time, Ning Chuan lived in the Flame Demon King's cave mansion, and most of the time he was discussing or communicating with the Flame Demon King, and when he was tired, the two would sit on the grassland and talk about some happy past events.

"The outside world is really exciting!"

When the Fire Demon King heard Ning Chuan introduce every food, wine, and beauty, his eyes were blue.

The so-called everyone has a love for beauty, although the Fire Demon King is a demon cultivator, but he is still very concerned about food, wine and beauty, especially beauty......

After staying for about ten days, feeling that the time was almost up, Ning Chuan took Qianqian and left the Flame Demon King's cave, and as soon as he left, Ning Chuan performed the ghost dance and hid in the void with Qianqian.

The most powerful thing about the white-haired eagle king is reconnaissance, which was what both the Mogu Demon King and the Fire Demon King had warned him, and Ning Chuan naturally didn't dare to slack off in the slightest, so as soon as he left, he showed the ghost dance.

Don't have a cave in the sky is not Nanling, this is the world of the four demon kings, all the demon cultivators have to look forward to the four demon kings, as long as Ning Chuan appears, I'm afraid it won't be long before the white-haired eagle king and the rat king will get the news, at that time, the two demon kings want to kill him, it's not too simple.

Eradicating what the Fire Demon King and the Mogu Demon King said in their mouths, Ning Chuan walked directly in the direction of the ancient tree, and encountered many powerful demon beasts along the way, their spiritual sense was very sensitive, and they seemed to feel Ning Chuan's approach.

But Ning Chuan was also very witty, he slowly learned how to avoid those demon cultivators, after walking for about a day and a night, the spiritual power around him became more and more intense, but he saw that there were streams flowing on the ground with clear water.

At first glance, there is nothing wrong with it, but as long as you observe it carefully, you will find that these streams are all condensed by the spiritual power of heaven and earth, and they are exactly the same as the waterfall in the cave of the Mogu Demon King.

It's just that none of the demon cultivators around the creek dare to get close to those streams, not because there is any danger, but because these spiritual powers are too strong, and in terms of their strength, they can't withstand those powers at all, as long as they absorb a little, I'm afraid they will explode and die.

"It seems that as long as you follow these streams, you can find the legendary ancient trees!"

Ning Chuan thought to himself in his heart, and his steps in the void couldn't help but slow down a little.

After another day's journey, the powerful spiritual power oppression had already made Ning Chuan feel the pressure, his face and body were all soaked with sweat, one can imagine how powerful these spiritual powers were.

Today's Ning Chuan is like being in the belly of a strong man, no matter what he does, he can't escape the control of that strong man, this feeling is the first time Ning Chuan has encountered it.

Different from Ning Chuan's sense of oppression, Qianqian, who was standing beside him, seemed very calm, and in her eyes, Ning Chuan seemed to see a look of enjoyment.

"Could it be...... With such a powerful spiritual power, doesn't it have any effect on Qianqian?"

Ning Chuan was shocked in his heart, this kind of spiritual power strength was no longer something that a cultivator of his level could bear, but Qianqian, a little girl, was not affected.

Thinking of what the Mogu Demon King and the Fire Demon King said at the beginning, even they would feel oppression here, but Qianqian didn't, does this mean that Qianqian's strength is stronger than the previous two demon kings?

"Brother, are you feeling unwell?"

Seeing Ning Chuan's eyes, Qianqian smiled slightly, gently held Ning Chuan's hands, and a cold feeling spread throughout Ning Chuan's body, and the next moment, the feeling of oppression in Ning Chuan's body receded like a tide and disappeared without a trace.

"Qianqian...... What the hell are you coming from?"

At this time, Ning Chuan couldn't hold back the kindness in his heart anymore, and couldn't help but ask.

Qianqian, who seems to be innocent, has too many secrets on her body, although Ning Chuan suppressed himself again and again, don't think about it, but whenever Qianqian's actions are so surprising, he can't help but think nonsense.

At this moment, Ning Chuan couldn't hold back any longer, and when he said it, he just wanted Qianqian to tell him what was going on.

"Hmm...... Qianqian can't tell you!"

A hint of surprise flashed in Qianqian's eyes, but she quickly regained her composure and lowered her head. Said softly.

A trace of coolness came from his heart, Ning Chuan also regained a little consciousness, and after being stunned for a moment, he said: "It's okay, you will always be my sister!"

After finishing speaking, Ning Chuan took the initiative to take Qianqian's hand and continued to walk forward.

No matter what Qianqian's identity is, he is Ning Chuan's sister, and the reason why he asked it just now was because he was too curious.

The moment he saw Qianqian's eyes, Ning Chuan knew that Qianqian had something unspeakable, and he realized that he shouldn't ask.

Without that sense of oppression, Ning Chuan's speed was also much faster, or because of the episode just now, the two didn't speak again, and both of them were silent along the way, and there seemed to be a trace of mustard in the hearts of the two.

Stopping again, Qianqian opened her mouth and said, "Little brother, I know it's not good to hide you, but when the time is right, I'll tell you!"

"I see!"

Gently touching Qianqian's head, Ning Chuan said with pity, the current Qianqian is like a child who has done something wrong, asking for his forgiveness.

Everyone has their own secrets, Ning Chuan is no exception, and Qianqian's identity is like a fog.

For a long time, Ning Chuan regarded Qianqian as his sister, but he ignored her **.

"Brother won't blame you, no matter who Qianqian is, it's my sister!"

Seeing that Qianqian was still a little uneasy, Ning Chuan added another sentence, and after hearing this, Qianqian smiled and regained her old smile again.

"That's good! Qianqian will always be the younger sister of the little brother!"

After eliminating the unhappiness in their hearts, the two continued to walk forward, and after walking for about a quarter of an hour, Ning Chuan stopped, turned around and said to Qianqian: "Qianqian, take back your power in me, I want to try the power in this, how powerful it is!"

"But ......"

After Qianqian heard this, she was a little worried in her heart, but Ning Chuan nodded and said, "It's okay, I'm confident, you can take it back little by little!"

The coercion outside had already made Ning Chuan feel extremely oppressive, and now Ning Chuan wanted to feel how powerful the power was here, otherwise, the coercion in the legendary ancient tree would definitely be even stronger, and now that he is here, it can be regarded as a preparation in advance.
