This smog is not ordinary smog. It is a smog that comes out of the extreme and is slowly exiled.

"I can't see it clearly, I have to go in and explore the reality." Ye Tian shook his head helplessly and said.

The two of them thought about it over and over again, and it seemed that there was only one way at the moment. As soon as they stepped into the smog, a feeling of stuffiness hit the hearts of the two.

The haze seems to contain some toxin. Fortunately, it only temporarily paralyzed the nerves, but it did not cause any substantial harm to the two.

"The visibility is too low, and I don't know how to search for the smog heart." The spirit of nature tried to stretch out his hand, but found that it was impossible to see clearly at all.

For this reason, Ye Tian also shook his head. It would be fine if the smog and thorny land was smaller, but if it was as huge as the world of rebirth, the two might have to go for ten days and ten nights.

"According to ancient books, the center of the smog and thorny land can be found by just following the thorns on the road." The Spirit of Nature thought for a while and spoke.

Ye Tian relied on touch to sense the ground, but he didn't have any special feeling.

The two of them hit the wall everywhere, walking through the smog and thorny land with visibility of less than three inches. Finally, hard work pays off, and Ye Tian's feet accidentally touched a thorn!

The thorn grows strangely, and it is in a straight line. Since that's the case, the direction is finalized.

Ye Tian led the spirit of nature and walked in the direction of the thorns. It was unknown how long they walked before they hit the wall again.

"This... looks like a tree." Ye Tian held his forehead and felt a stinging sensation, as if a tiny needle had penetrated into his mind.

The pain that still hits the soul has nothing to do with the strength of the body.

The Spirit of Nature tried to reach out her hand to sense the so-called "tree". Soon, she got the answer.

"This is an ancient tree that has grown for millions of years. It has existed here since its creation. From below, there are still terrible auras. If that's right, the heart of haze is in the ancient tree."

Ye Tian nodded when he heard this and immediately swung several swords! In a trance, a loud bang came.

The ancient tree... fell to the ground with a bang!

At this moment, the visibility of the two people suddenly increased. It can be seen that part of the smog has dissipated.

Ye Tian searched for the trace and cut open the ancient tree, but only saw a fan-shaped gray fragment.

"This should be the fragment of the heart of haze." Ye Tian said, then observed the shape of the fragment and initially concluded that there were four fragments in total.

Every time a piece of fragments is filled, the haze will dissipate a little. Ye Tian vaguely saw some black shadows through the haze.

"Some monster seems to have appeared around..." The Spirit of Nature frowned and his eyes kept sweeping around.

Ye Tian nodded, but he had to get closer to know what kind of monster it was.

As soon as the two of them were about to get up and walk again, a strange creature appeared behind them.

The creature was a wooden board, but it was covered with human organs. He also held a wooden sword and a wooden shield. He didn't look like a strong man no matter how he looked.

But it was such a creature that informed Ye Tian of a terrible strength - the ninth level of the Wilderness Realm during Ye Tian's small-scale detection.

The Spirit of Nature quietly took a step back, pulled La Yetian's clothes and said, "This kind of monster is called the Eternal Tree Guard. Don't look at their body material. Their real defense strength is still very high. And once this kind of guy fights, it will only increase and be unfavorable to us."

When Ye Tian heard this, he naturally gave up the idea of ​​killing him. Now, the speed can be as fast as possible.

Otherwise, when the world barrier provided by the Heart of the World completely disappears, the entire continent will be in chaos, and Ye Tian may not be able to protect himself.

While the two of them retreated, they encountered thorns again. However, this time the thorns were much stronger than the previous depression.

"The visibility is too low, and even I can't detect the end of this thorn, so I can only try one of the roads at random." The Spirit of Nature squatted down, stroked the thorns and spoke.

Ye Tian walked towards the road with the densest number of thorns, and at the same time, this was also the most difficult road.

Although these thorns do not harm the two, they will restrict their walking speed.

Moreover, there are guards of immortal trees around it, so it is not easy to do.

At the end of this road with the largest number of thorns, there is another ancient tree. Now, Ye Tian looked up and could see the branches and leaves.

The sword of the Immortal Sword was still slashed out, and the ancient tree collapsed with a bang. Ye Tian took out the haze fragments in it again.

This time, the visibility around us increased again. So, the two of them followed suit and returned to the previous thorny place.

After searching according to the location of each thorn, Ye Tian quickly determined something. This was indeed a thorn, corresponding to an ancient tree.

It’s just that the thorns are complicated and there are many repetitive places, so it’s easy to go all the way.

In the end, Ye Tian cut off four ancient trees and had already taken four fragments in his hand. Unfortunately, these fragments seemed to be a bit different from what he imagined.

Even if the four pieces are spliced ​​together, they are a little bit different. In the center of the fragment, it seems that a gem of some kind can be placed.

"The haze has not completely dissipated, and there is a fifth ancient tree in the thorny land, but we have not yet found it." The spirit of nature looked around and said.

For some reason, Ye Tian suddenly raised his head and his eyes locked on the sky.

He looked closely and saw the Demon King's eyes back again. A sensation of pain came, but Ye Tian saw clearly the objects above the sky in a trance.

It was an ancient tree, an extremely huge ancient tree. Ye Tian walked towards that direction by himself. Seeing this, the spirit of nature said nothing, but just followed closely behind.

Ye Tian's perception is already richer than hers, so it is not surprising that he finds something first.

I don’t know how long I walked, but the spirit of nature also saw the black shadows above the sky.

"That...that is the ancient tree that is the sky?!" The Spirit of Nature seemed a little surprised and could not turn his eyes away from the ancient tree.

"Tongtian Ancient Tree? Have you seen it?" Ye Tian said, walking leisurely on the road.

The guards of the trees of immortality around them gradually decreased and they were never seen again until now.

When the Spirit of Nature heard this, he was stunned and then said, "That ancient tree that opens to heaven is a product of mythology even in my time."

"It is said that the height of the ancient tree of Tongtian is extremely terrifying. It goes straight to the sky, and it is even more unknown at the end. I spent my whole life looking for its trace, but I never saw it. So, I thought that such a location did not exist at one time."

Ye Tian became interested when he heard this. It has been a mythical product since ancient times. Who knows how many worlds are hidden?

"There are many trial places within the ancient tree of Tongtian. Only by passing layers of trials can you reach the top. I still remember that the strength of the tree demons in it will only become similar to the challenger." The Spirit of Nature said word by word.

Then, the Spirit of Nature added another sentence: "These are recorded in books from a long time ago. I don't know whether this is true within the world now."

The two walked into the ancient tree to the sky and saw a passage appearing. Unfortunately, there was a rich haze at the entrance of the passage, and it was impossible to see through the inside.

After hesitating for a while, the two of them finally walked in. As soon as they stepped on their feet, the hole behind them was locked by rattan and thorns, and these rattan and thorns were not ordinary goods.

"This is the immortal vine and the thorns." Nature Ling Dai's eyebrows slightly frowned and explained, "These two plants have powerful isolation functions that can prevent us from breaking their restrictions..."

Ye Tian nodded silently when he heard this: "It seems that this is to keep us from coming and going."

Then, his eyes were placed inside the ancient tree of Tongtian. To the outside world, the cave inside looked even more magnificent.

And the ground of this ancient tree is all spliced ​​together by twisted branches.

In the direction opposite to the door, there was a staircase walking upwards. Ye Tian tried to fly, but there were vines coming quickly to harass him.

Although Ye Tian could resist these vines, he was slower than he could walk upright.

As of now, there is no threat to the first floor of the ancient tree, except for the occasional vines.

"Don't take it lightly when you see that nothing has happened now. The horror of the ancient tree in the sky has been seen by our predecessors." The spirit of nature looked at Ye Tian, ​​who was content with his leisurely and contentment.

In fact, Ye Tian knew very well about this, but he was not afraid of dealing with such things.

As soon as I walked a few steps, the space began to tremble, especially around Ye Tian, ​​the branches under my feet began to intertwine...

With a loud bang, countless strange tree monsters soared from the ground! They stretched out the vines on their hands, trying to tie the two of them up.

Faced with this situation, Ye Tian had no intention of panic, but just pulled out the Zhenxian Sword indifferently and resisted in turn.

Although there are many tree demons, they are vulnerable under Ye Tian's sword technique. Even if hundreds of tree demons attack at the same time, Ye Tian can resist it!

The spirit of nature was chanting something lightly, and then a giant lotus bloomed from under her feet, swallowing most of the tree demons!

Ye Tian swung a sword from the side. The sword flames filled ten miles and instantly killed nearly a hundred tree demons!

At the same time, the entire layer began to burn continuously. But from time to time, rattans would appear and extinguish the flames.

"Steping at the ancient tree of the sky is not a waste of time here." Ye Tian said to the spirit of nature, and pointed to the steps not far away.

The Spirit of Nature seems to have no action at this moment, but in fact, her mind... is bound!

Ye Tian just glanced at it and realized the seriousness of the matter. He hurriedly dispersed the demonic ashes and leaned against the spirit of nature.

In addition to its terrifying aggression, Demon Ear also has extremely strong brushing ability. Whether it is the divine mark or the inner demon, it is no problem for it.

"Cough cough..." The next second, the spirit of nature returned to normal, but instead coughed up a mouthful of green blood.

"What a terrible blood suppression..." The Spirit of Nature said with a dark face, "At the highest level of the ancient tree of the sky, there is a guy's ability... far exceeding me."

Ye Tian fell into deep thought when he heard this. He originally thought that the seven elements were the ultimate elemental realm, but he never thought that there was someone who could appear stronger than their elemental attainments.

"Since that's the case, I went to the top floor and asked him for an explanation." Ye Tian said, heading to the second floor.

The two of them always faced these low-level monsters. After all, Ye Tian's ability is too powerful, and it only takes a blink of an eye to pass the hurdles and kill the generals.

I don’t know how long I went forward, but the more time and energy I spent became more and more. In the end, Ye Tian also seemed a little weak.

"The next level is the nineteenth level, followed by the so-called twentyth level, and the last level?" Ye Tian moved Zhou Tian, ​​causing the magic core in his body to continuously breathe, enhancing his own breath.

The Spirit of Nature nodded: "If ancient books have not been faked, then the lower layer is the last layer. And among them, there is a tree demon who has almost become an immortal, extremely powerful."

Ye Tian nodded and closed his eyes slightly. He had consumed too much energy just now and needed some conditioning now.

About three days later, Ye Tian's blood-red pupils suddenly opened, and a strange aura filled the air.

"It's good to do this." Ye Tian said, and he was about to walk towards the 19th floor.
To be continued...
