Start slaying demons from the proficiency panel.

The power of the Great Annihilation Spear Technique increases with the number of spears fired; the more spears fired, the greater the power.

However, it's not as simple as just finding some ordinary guns to unleash the Great Annihilation Gun Technique. If the material is too ordinary, the guns themselves will be destroyed by the terrifying power of the Great Annihilation Gun Technique without Ning Xiu even having to activate them.

Therefore, Ning Xiu currently only has three guns that meet the requirements for using the Great Annihilation Gun Technique.

Although that attack just now managed to injure the Divine Tree Emperor, you can't guarantee victory against powerful figures like those from the previous era if you can't seize the opportunity to kill them in one blow.

A single hidden killing move in the Inner Realm is a world-destroying force for someone at the Dragon-Elephant Upper Realm.

By forcefully stimulating his inner potential with the life force of the spear, the Divine Tree Emperor's aura was even stronger than before, and his whole body began to emit a green light.

Numerous branches and vines sprouted from his skin, then grew wildly, with the branches and roots all burrowing into the earth and merging with it.

You can see that the tree roots are like IV tubing, constantly expanding and contracting, as if extracting something from the ground and then pouring it into the body of the Divine Tree Emperor.

With the help of this, the Divine Tree Emperor's size is constantly growing larger and larger, and its entire body is beginning to evolve into a half-human, half-tree form, reaching a height of several tens of feet in no time.

"His true form is derived from the essence of the earth," the True Yang Emperor explained.

"What is Earth Spirit Juice? Is this a technique that only those at the Inner Realm Saint Realm can master?" Ning Xiu asked hurriedly.

This True Yang Emperor is really getting worse and worse. He doesn't reveal important information in advance, but waits until things have already happened before giving a sudden dose of "science popularization".

"No, the essence of the earth is something that exists in the world itself, and it has extremely powerful effects. However, not all living beings have the ability to use it."

"The spirit wood demons actually have a better chance than the humans. I have never seen any human who can utilize the earth's spiritual essence, so I have never mentioned this to you before," Emperor Zhenyang sighed.

Ning Xiu: "What are my chances of winning against him now?"

"It's hard to say. The effects of the Earth Spirit Essence vary from creature to creature. Some can enhance their physique, some can activate their potential, and some can evolve into a Dharma body. I need to see what changes this guy has undergone first."

"what!"

The lower half of the Divine Tree Emperor's body had become rooted in the earth, just like a tree. His skin had become like a tree, ancient and rough.

Sharp wooden thorns grew from the body of the Divine Tree Emperor, their surfaces gleaming with a dark luster, clearly indicating they were poisonous.

Half-human, half-tree, the oppressive feeling that the Divine Tree Emperor brought to Ning Xiu at this moment was significantly stronger than that of the locust tree demon he encountered in the Evil Barbarian City.

"It's a Dharma Form! This guy can actually unleash such power with the help of the earth's spiritual essence," Emperor Zhenyang exclaimed.

The Dharma Form is a power similar to the Saint Form, but while every Dragon Elephant Realm expert possesses the Saint Form, the Dharma Form is not so absolute.

Whether one can grasp the Dharma Form depends entirely on opportunity and luck; even a powerful emperor cannot force the acquisition of the Dharma Form.

The methods currently being used by the Divine Tree Emperor are the power of the Dharma Image.

"I did not intend to use this move to fight you. Since I was able to kill you, it was also a huge drain on me. You should be glad, glad that you were able to die under my Dharma form."

With a flick of his hands, the Divine Tree Emperor caused the earth to rumble and crack, and a disc-shaped piece of land was lifted off the ground by countless tree roots and carried into the sky.

The tree roots lifted the tree at an extremely fast speed, and in just a few breaths, they had already lifted the Divine Tree Emperor and Ning Xiu to a height of tens of thousands of feet above the ground.

The air here is extremely thin, and the temperature has dropped to the point where a drop of water can freeze. There are also violent gales blowing all around. Even an ordinary person would be frozen solid instantly here, and their blood would lose the ability to flow.

Ning Xiu took the Spring and Autumn Cicada Step, intending to leave this place, but he did not expect that the Divine Tree Emperor had anticipated this and had already woven a large net with tree roots, covering all sides without leaving any gaps, leaving Ning Xiu no room to escape at all.

The altitude continued to rise, and the surrounding temperature had dropped to an alarming level, with a thin layer of frost forming on Ning Xiu's body.

This was only because he had cultivated the Heaven-Burning Scripture, and his internal energy and blood were as vigorous as raging fire and true yang; otherwise, he would have been frozen into a lump of ice long ago.

In contrast, the Divine Tree Emperor showed no abnormalities whatsoever, as if it had not been affected at all. This was probably due to its Dharma form; its half-human, half-tree state allowed it to effectively resist the cold air from high altitudes.

boom!

Ning Xiu refined his martial arts acupoints in his chest, and a large amount of internal energy from the Burning Heaven surged out, forming a ring of fire around his body, which kept all the cold air outside the ring of fire.

"Let's see how long you can hold out. Today I'll show you the real difference between the Dragon Elephant Upper Realm and the Inner Realm Saint Realm," the Divine Wood Emperor sneered.

The surrounding sky grew increasingly bright and dazzling. Ning Xiu then saw a completely green canopy above his head, with countless strands of green fluff twisting and turning at the other end of the canopy, creating a breathtakingly beautiful scene.

"Oh no, this guy actually brought you to the Ninth Heaven of Gale!" Emperor Zhenyang said in rare shock.

Ning Xiu had previously heard the True Yang Emperor mention the Ninefold Gale Realm, where the sky was filled with nine layers of gales, each more terrifying than the last.

Any cultivator who tries to pass through the Ninefold Gale will suffer from its torment. If they cannot withstand it, they will either perish or have their soul scattered.

Each layer of gale is more powerful than the last. Even the True Yang Emperor failed to pass through the ninth layer of gale to see what the scenery was like outside the nine-layered gale boundary and whether he could leave this realm.

For those at the Dragon-Elephant Upper Realm, even the first level of the Gale Realm is extremely terrifying. Physical strength alone is simply insufficient to resist it, and if one stays there for too long, one will die inside.

It was obvious that Emperor Shenmu saw that he was unable to deal with Ning Xiu's Great Annihilation Spear Technique, so he planned to use external forces to forcibly kill Ning Xiu.

With the power of his Dharma form, he could easily wear Ning Xiu down to death in the Ninefold Gale Realm.

"Boy, you must find a way to escape. You absolutely cannot let him take you into the Ninefold Gale Realm. That's not something you can handle right now," Emperor Zhenyang said anxiously.

But it was a bit too late to say that. Since the Divine Tree Emperor had this plan, he had naturally made all the necessary preparations long ago.

Ning Xiu will not be given any chance to escape. He has no choice but to enter this Nine Heavens Gale Realm, even if he doesn't want to.

Supported by the tree roots, Ning Xiu and his companion were propelled into the sky. The moment they passed through the sky, the surroundings changed drastically.

Originally, it was just the extreme cold at high altitude that made people feel uncomfortable, as if their blood was about to freeze.

However, once they entered the Nine Heavens Gale Realm, the situation changed dramatically in an instant.

The wind howled like a raging storm. The gentle breeze on the ground transformed into the sharpest blades within the Nine Heavens Gale Realm, stinging the skin as if cut by a sharp knife.

The protection of the inner force of the Burning Heaven was rendered useless at this moment. The wind of the Nine Heavens Gale Realm was like an invisible force, able to penetrate and ignore the martial artist's inner force.

Ning Xiu quickly released his protective golden bell, but the result was the same. The protective golden bell, which had always been invincible, was now ineffective.

The gale was impenetrable, and it drew blood from Ning Xiu's body. Even the body of the Great Black Heaven of the Floating Pagoda was cracked and scarred.

"Hahaha!" The Divine Tree Emperor laughed heartily. Relying on the power of his Dharma form, his injuries were far less severe than Ning Xiu's. He could stay in the first level of the Nine Heavens Gale Realm and wear Ning Xiu down until he died.

Furthermore, the tree roots can infuse the Earth's spiritual essence into the Divine Tree Emperor's body, repairing his physical condition and making him invincible the moment he enters the Nine Heavens Gale Realm.

Looking at the wounds on his body, Ning Xiu thought, "That bastard Shenmu Emperor, after bringing me into the Nine Heavens Gale Realm, immediately adopted a defensive stance, clearly intending to cheat and exhaust Ning Xiu until he died with resentment."

The entire area was sealed off by the Divine Tree Emperor. Unless Ning Xiu possessed a higher cultivation level than the Divine Tree Emperor, he would not be able to break through the blockade and escape the encirclement in a short period of time.

Thinking of this, Ning Xiu's ruthlessness also rose. Since you want to play such tricks, then I will play along with you to the end.

Then Ning Xiu planted the three spears in his hands into the ground, grabbed the ground with his six arms, and began to press it down forcefully.

The land that was being lifted up by the Divine Tree Emperor was already very unstable. Under Ning Xiu's strong influence, it began to flip over in no time, tilting the entire land. The Divine Tree Emperor, which was originally standing upright, was now upside down.

This left him feeling very puzzled and confused. He didn't understand what Ning Xiu was struggling for. Even if he smashed this piece of land to pieces today, he still wouldn't be able to escape the Nine Heavens Gale Realm.

But at that moment, Ning Xiu unleashed the Great Annihilation Spear Technique. The three spears, carrying terrifying annihilation power, pushed the entire tectonic plate higher.

Judging from this, their target is clearly the second level of the Nine Heavens Gale Realm.

The speed of the Great Annihilation Spear Technique was not much slower than that of the Divine Tree Emperor. In just a few breaths, the two of them braved the strong winds and saw the second layer of the sky.

The gale-force winds within this layer of sky turned red at first, and the very air emanating from it was filled with a destructive power that sent chills down one's spine.

The Divine Tree Emperor's expression changed drastically: "You want to go to the second level? You're insane! You'll only die faster there. Do you intend to fight me to the death?!"

Even though the Divine Tree Emperor is an injured Inner Realm Saint, he simply cannot withstand the second level of the Nine Heavens Gale Realm. He will die in the gale within half an incense stick's time, unable to even escape.

As for Ning Xiu, whose cultivation level was even weaker than his, there's no need to say more; he would only die even faster.

“Staying in this level is death anyway. Since you can still live, why don’t we die together?” Ning Xiu laughed wildly.

His expression seemed to indicate a willingness to die, which terrified the Divine Wood Emperor. He had brought Ning Xiu to the Nine Heavens Gale Realm to kill him, but he had no intention of sacrificing himself as well.

The Divine Tree Emperor never expected Ning Xiu to take such a desperate gamble.

Because the Dragon Elephant Realm does not have the ability to reach the Nine Heavens Gale Realm, given the current situation, very few people know about the Nine Heavens Gale Realm.

But what the Divine Tree Emperor never expected was that Ning Xiu seemed to know the secrets of the Nine Heavens Gale Realm, and also knew that there was a second heaven above the first heaven.

This struck at the Divine Tree Emperor's Achilles' heel, instantly putting him in a life-or-death situation.

call out!

Before the Divine Tree Emperor could react, the two plunged into the second layer of gale force. The blood-red gale force continued to whip around, even more powerful and terrifying than the previous one.

Even with the support of the earth's spiritual essence, the Divine Tree Emperor still suffered numerous injuries, with torn bark peeling off his body to reveal the internal wounds.

"Madman! What a madman!" the Divine Tree Emperor roared, hurriedly dispersing the tree roots supporting the land beneath his feet, intending to let the land fall back to earth and leave the Nine Heavens Gale Realm.

Although that wouldn't kill Ning Xiu, at least he managed to save his own life.

Unexpectedly, Ning Xiu also saw through the Divine Tree Emperor's intention. He unleashed six punches downwards, and a tremendous force burst forth, even producing a sonic boom. A counterforce surged out, and the land rose instead of falling, flying towards the higher Gangfeng Realm.

Click click click!

The crimson gale, like a knife, struck Ning Xiu's body, tearing open wounds several inches long. If they were ordinary wounds, Ning Xiu could have healed them instantly thanks to the self-healing ability of the Great Black Heaven.

However, the wounds caused by the gale have a tearing ability that prevents them from healing, leaving them in place. Even if you are at the Dragon Elephant Upper Realm, you can only watch helplessly as you bleed more and more.

On the other hand, the Divine Tree Emperor was in no better condition. Most of its bark had fallen off, and it no longer had the arrogant demeanor it had shown earlier. Instead, it was extremely flustered and furious.

With the tree roots that supported the land gone, he naturally lost the support of the earth's spiritual essence, and thus his self-healing ability was no longer as strong as before.

If he continues to be trapped in the second layer of the Gale Realm by Ning Xiu, he will eventually die.

Having survived the previous era, the Divine Tree Emperor must have had a strong obsession with survival. He wanted to heal his injuries and live until the next Yangyao descended.

Numerous tree roots grew out of the Divine Tree Emperor's body, enveloping him like a wooden ball in an attempt to resist the onslaught of the crimson gale.

At this height of tens of thousands of feet, even those at the Inner Realm Saint Realm would become extremely powerless for a time.

The most terrifying thing about the Nine Heavens Gale Realm is that the gales here are formless and intangible, and they have a great destructive power against the power of thought. As soon as you use the power of thought, you will be destroyed by the gales.

As a result, the Divine Tree Emperor was unable to use his mental power to help himself escape from this place for a time.

"Are you crazy? Although sending him into the second level of the Gale Realm is a way to die together, and even if he dies, we can't let the enemy benefit, you will die too if you continue like this. I don't think you are such an irrational person. Do you have some other means to save your life?" Emperor Zhenyang asked suspiciously.

Having spent time with Ning Xiu, he had gained a considerable understanding of Ning Xiu's personality and did not think that Ning Xiu was the kind of person who would easily risk everything to fight to the death with someone.

Rather than die together, Emperor Zhenyang felt that Ning Xiu would rather seek a way to survive.

"If I kill him and gain a few more comprehension points, I will have a great chance to break through to the Dragon Elephant Upper Realm today and fully achieve the Inner Realm. Taking advantage of the Gale Realm is a good opportunity. Otherwise, if I want to kill the Divine Wood Emperor, I'm afraid it won't be as easy as when I faced that woman last time." Ning Xiu thought to himself, without replying to the True Yang Emperor's question.

Some things don't need to be said now; others will understand when everything settles down.

"Stop right now! Don't go any higher!" the Divine Tree Emperor roared, and with a wave of his hand, thousands of tree roots hardened into straight lines, transforming into countless spears that pierced towards Ning Xiu's location.

Ning Xiu unleashed six punches, transforming a large amount of internal energy into fist force that surged forth to meet the Divine Wood Emperor's killing move head-on.

Wooden guns filled the sky, and flames roared overhead.

Following the opposition between life and annihilation, the two once again demonstrated the power of mutual restraint.
