After reshaping his body, Ning Chuan's sense of pressure from spiritual power was almost immune, and after no worries, the flight speed of the two of them was extremely fast, and they followed the feeling in their hearts to walk, and two days later, a tree exuding emerald green appeared in front of Ning Chuan's eyes.

This place is simply a dangerous situation, and Ning Chuan, who finally saw the mysterious ancient tree, couldn't help but gasp at this time.

Originally, in his impression, the mysterious ancient tree should be a towering tree, like the backbone of heaven and earth, running through heaven and earth, but the ancient tree he saw at this moment was not like this.

This is a willow tree, the wicker is hanging down, verdant, above the trunk, there is no trace of age, full of life, those willows, like his tentacles, are full of spirituality.

"It is worthy of being an ancient tree for countless years, it is simply a god of heaven and earth!"

This was originally just an ordinary willow tree, but after a long time and rich spiritual power soaking, it seemed to have spirituality, and the vitality contained in those willows seemed to be much better than the mysterious green juice.

"Boom!"

When Ning Chuan approached the willow tree, the entire heaven and earth began to tremble, and almost at the same time, a pillar of light burst out from all four directions, rushing straight into the sky, and the direction corresponding to these four pillars of light was the direction where the Four Great Demon King Cave Mansions were located.

"Have you go?"

The Flame Demon King and the Mogu Demon King murmured softly, and then tore through the void and left.

"Could it be Ning Chuan? He's not dead?"

The white-haired Eagle King and the Rat King also got the information at this time and also rushed over.

The light gradually converged, and in just three or four breaths, the four demon kings appeared in four directions.

"Bold Ning Chuan, he dares to trespass into a forbidden place!"

The first to speak was the Rat King, the place where the ancient tree is located, related to the entire Cave Heaven, and this is the forbidden place for all demon cultivators, except for the four demon kings, other demon cultivators are not allowed to get close to half a step.

Now that Ning Chuan is here, the four demon kings can directly kill Ning Chuan!

Mo Gu and the Fire Demon King had already made inferences in their hearts, so they didn't say anything, but the eyes of the Mo Gu Demon King were terrifyingly deep.

Where the ancient tree was, he hadn't told Ning Chuan, and similarly, the Fire Demon King hadn't told Ning Chuan, it was indeed a skill to be able to find it in such a short period of time.

Moreover, Ning Chuan's calm appearance when he stood around was what surprised the Mogu Demon King the most.

The strength of their four demon kings, each of them was stronger than Ning Chuan, but in the face of the spiritual power emitted by the ancient tree, they all had a lot of pressure, and they couldn't do it without pressure like Ning Chuan at all.

Looking at the four demon kings, Ning Chuan was not surprised, after all, the Flame Demon King had already warned him that if he got close to the ancient tree, the four demon kings would all make a move, and they would not say anything about it.

"Ji Huo, what's the solution now?"

The face was extremely calm, but it didn't mean that Ning Chuan would be restrained, before approaching the ancient tree, Blue Jihuo told him not to worry, and now at this time, it was for Blue Jihuo to behave.

But...... The blue Himehuo doesn't seem to make any sound!

No matter how Ning Chuan called him, he always looked like he didn't care about himself and hung high.

"Damn, Blue Himehuo, you dare to calculate me!?"

Even if Ning Chuan's quality was good, he couldn't help but scold at this time, he knew that his catties, if it weren't for the help of Blue Ji Huo, Ning Chuan would not have come here for anything, after all, the four demon kings were not something he could hostile to.

"Panic what, I won't let you die!"

In the sound of Ning Chuan's cursing, the slow voice of the blue Ji Huo came, and Ning Chuan settled down a little, otherwise, he would really go berserk.

"Agni, Mogu, what should I do now, do you understand?"

The white-haired Eagle King spoke, his meaning was very obvious, he wanted Agni Fire and Mo Gu to take action against Ning Chuan.

He knew that Ning Chuan had crossed paths with the two, and there was a lot of kindness in them, but he still let him do it, obviously to retaliate against Ning Chuan for not handing over martial arts to them.

"Could it be that your white-haired Eagle King was beaten by me last time and couldn't even solve a Returning Yuan Realm cultivator?"

Mo Gu smiled slightly and said lightly.

The white-haired Eagle King didn't suffer any damage last time, but the Rat King, the damage suffered by the flames on the tail is still clearly visible, and as soon as Mo Gu's voice fell, the Rat King's face drooped.

"Humph!"

The Rat King snorted coldly, took a step forward, and said coldly: "Since you are not willing to make a move, then it is up to me to kill this human who trespassed into the forbidden land!"

For the crime of trespassing in the forbidden land, even the Fire Demon King and the Mogu Demon King did not dare to help at will, and now that the Demon King has made a move, it can be said that he killed Ning Chuan in the name of sincerity, and neither of them dared to complain.

"What now?"

With frowning brows, Ning Chuan hurriedly asked Blue Ji Huo.

He can't bear a rat king anymore, and if he waits for the white-haired eagle king to make a move, he will be dead.

"Fight him! When you can't hold on, I'll tell you what to do!"

Blue Ji Huo's old-fashioned words almost made Ning Chuan half angry, if he had the strength to match the demon king, would he be so flustered, this blue Ji Huo was clearly pushing him into the fire pit.

"Put your mentality in place, what it was like when you fought outside, that's what it is like now, bring out your best form!"

The voice of the blue Ji Huo came again, and this sentence reminded Ning Chuan.

The enemy is very strong, which is not bad, but it seems that Ning Chuan would not have such a timid scene when facing anyone, and now that he has come to this cave, why has he become so cringe?

Thinking of this, Ning Chuan took a deep breath, then took a step forward, and said with a smile: "You didn't kill me last time, do you think you can kill me again now?"

The self-confidence in his heart recovered, but when it fell into the ears of the Rat King, it seemed like arrogance, and this kind of arrogance could only be possessed by the Demon King, Ning Chuan, a cultivator of the Returning Yuan Realm, did not deserve such an arrogant demeanor at all!

"Last time someone helped you, this time it won't be so lucky!"

After the Rat King sneered, the demon yuan force ran wildly from his body, pulling the heavens and the earth to change color, and a gust of wind blew out of thin air, blowing the wicker not far away.

If it was before, in the face of such a might, Ning Chuan would be more or less suppressed, but now I don't know why, Ning Chuan couldn't feel the slightest strength of the Rat King's breath, as if what was in front of him was just like an ordinary cultivator, not the Demon King.

"Is it because of the ancient tree's spiritual power to reshape the physical body?"

Ning Chuan secretly speculated in his heart, but he didn't dare to slack off in his hand, and the Overlord Divine Skill and the Blood Dragon Ascension were instantly displayed.

Different from usual, this time after Ning Chuan's whole body turned red, there were dark red lines, flowing in the sound of the flesh, not only that, those lines seemed to emanate from the imperial bones, and the power in them was even more terrifying!

"This force...... It's the power of the Emperor's Bone!"

Clenched his fists, Ning Chuan said in a deep voice.

This power is no stranger to him, if he didn't launch the Heavenly Dao Tribulation Thunder, it wouldn't have appeared at all, but now it is circulating throughout his body.

"Come on!"

This discovery greatly increased Ning Chuan's confidence, raised his head, and looked at the rat king with gloomy eyes, Ning Chuan confidently went straight to the sky.

Every time he breaks through, he wants to test his strength, and now the person who "accompanies" him to test his strength is the demon king, the strongest of the strong, which is even more exciting.

"I haven't seen anyone who wants to die as much as you!"

After the Rat King snorted coldly, a huge brown ball condensed above his head.

This round ball is simply the demon yuan force, it is extremely pure, and it is also the most direct way of operation of the demon yuan force, not to mention anything else, if Ning Chuan hits this round ball, I am afraid that he will be torn to pieces by the violent demon yuan force in it!

This is the most simple and crude use of demon yuan power by the demon cultivator in the Cave Heaven, and Ning Chuan also did not dare to slack off in the slightest when facing such an attack.

"Whew!"

The void of both hands was pressed, and the brown ball roared, and where it passed, the void was annihilated, and a huge ravine was cut above the mid-air, and the power of the void could be felt faintly.

"With such a reckless move, aren't you afraid of destroying the ancient tree?"

Frowning, Ning Chuan secretly guessed in his heart.

As if to answer the question in Ning Chuan's heart, the surrounding of the willow tree, condensed a layer of emerald green light, wrapped the willow tree in it, that kind of power, extremely pure, the brown ball of the rat king under this emerald green light, all looked eclipsed.

"This tree is really refined!"

After muttering softly, Ning Chuan didn't have an estimate, with a little bit of his feet, Luo Yanbu quickly unleashed, and a powerful force came from under his feet, and in an instant Ning Chuan dodged the attack of the brown ball.

"Boom!"

The attack landed on the green light curtain of the ancient tree, and a powerful explosion erupted, which was deafening, but soon, those demon yuan forces were essence, and quickly disappeared between heaven and earth, or rather, they were absorbed by the willow tree.

Before he could take a closer look, the Rat King had already moved again, he knew that Ning Chuan's speed was extraordinary, so now he didn't plan to give Ning Chuan the slightest respite!

"Bang bang bang!"

Between his two hands, one after another Demon Yuan Force balls flew out, densely packed, as if they were sharp arrows, shooting towards Ning Chuan, because the speed was too fast, others could not see its trajectory clearly at all, and could only see white shadows one after another.

"Yuan Li is profound, and there are many benefits!"

In the face of so many attacks, Ning Chuan used the Breath of Heaven and Earth and the Subtle Realm to be unleashed, and Luo Yan walked like a fish in water, frantically dodging the attack of the Rat King.

With such a powerful firepower, like a cannonball, if he attacked head-on, Ning Chuan would definitely not get any bargains, so Ning Chuan would not be so stupid!
