The fog seemed to be like a ghost from the Nine Shadows, churning and surging and vowing to devour everything.

The half-moon-shaped sword light emitted by Chen Xi flew out of a distance of about ten meters, and then completely lost its light in the dense fog.

Although this sword is just a casual swing of his hand, it is not a subtle move, but it is not so weak.

This situation really surprised Chen Xi, and it also made him put on a fighting state in an instant.

But something that surprised Chen Xi was......

He waited for a long time in the thick fog, but did not find any danger or danger lurking in the fog.

Everything was calm.

It seems to be just a natural fog.

Chen Xi held the Tianyan Divine Sword in his hand, frowning and constantly examining the dense fog in front of him.

His consciousness was so closed that he could only observe the outside world with his five senses.

The fog is so big that it can't be blown away if it can't be illuminated or blown away, even if there are balls of light in all directions, Chen Xi can only see the scene within a radius of ten meters at most.

This feeling really upset him......

Chen Xi stood in the thick fog and stood on guard for a long time.

It was a long time before he seemed to think of something, and a thoughtful expression suddenly appeared on his face.

So, he stretched out his arm and spread his palm upward.

A miniature Spirit Gathering Array immediately appeared in Chen Xi's palm.

And with the activation of the Spirit Gathering Array, a faint cyclone staggered up from his palm.

The Spirit Gathering Circle is the most basic magic circle, and its working principle is very simple.

After the arrangement is successful, it will be like a tornado, constantly rotating around the eye of the array to absorb the aura of the nearby heaven and earth.

Therefore, when the Spirit Gathering Array appeared, this cyclone condensed and formed at a speed visible to the naked eye, and its color became darker and darker, and finally turned into an extremely thick milky white.

In less than a minute, Chen Xi found that there was a cold feeling in his palm.

If you look closely, it turns out that there is a drop of water in the center of the cyclone.

Seeing this, Chen Xicai had a suddenly realized expression.

He finally understood what the fog was.

Just as water has three forms: gaseous, liquid, and solid, there are actually several forms of heaven and earth aura.

Under normal circumstances, mortals cannot see the aura of heaven and earth.

But if the aura of heaven and earth is too strong, then it will become as hazy as a fog.

The aura of heaven and earth in this form is also called spiritual mist by immortal cultivators.

Fog is liquid, but it is made up of tiny water droplets, which is why it can be suspended in the air.

In addition, when the aura of heaven and earth is rich to a certain extent, it will completely change from a gaseous state to a liquid state, which is also known as spiritual liquid.

Spiritual liquid is extremely rare, and Chen Xi has not seen it a few times in Tianxuan.

As for the solid heaven and earth aura, that is, the legendary spirit crystal, it has only been heard of and never seen, and it completely exists in the legend.

The reason why Chen Xi didn't tell that this was the spiritual mist at the first time was because the heaven and earth aura in this form was already self-contained.

Just like a balloon filled with water, every drop of spiritual mist contains surging heaven and earth aura, which will not leak, so only by popping the balloon can you feel the energy contained in it.

It turned out that above this huge oasis, there was actually a spiritual mist floating in the sky!

That's kind of interesting.

Chen Xi withdrew the Divine Sword Technique, and then operated the Magic Technique.

At that moment, his whole body seemed to have turned into a humanoid black hole, and he began to frantically devour the spiritual mist around him.

However, now was obviously not the time to cultivate, so he could only devour the spiritual mist while silently walking towards the depths of the oasis.

At this time, an idea suddenly popped up in Chen Xi's mind.

That mysterious village lurking in the depths of the Qinling Mountains, after hundreds of years of accumulation in the Great Array of Binding Spirits, had only set off a tide of spiritual energy that lasted less than a quarter of an hour.

The aura tide succeeded in opening the heavens and brought out the existence of the gods who completely surpassed the existing realm of the earth.

If......

The clan elders waited until the aura revived before opening the formation, could they directly open the gate of heaven?

Thinking of this, Chen Xi couldn't help but raise his eyebrows, and couldn't help but be a little curious about what was behind the Heavenly Gate.

God General, what level of existence should it be regarded as in the Gate of Heaven?

Chen Xi's thoughts drifted farther and farther away.

And at this moment, something that suddenly appeared in front of his eyes suddenly pulled his thoughts back.

A tree appeared in front of Chen Xi.

A huge tree.

Because the visibility was too low, Chen Xi could only circle around the tree.

It's a terrible turnaround.

The diameter of this tree is more than 20 meters, which means that the circumference of the base diameter of this tree is at least 70 or 80 meters.

If memory serves, during the day there are only a few trees and shrub seedlings in this place, in addition to the green meadows.

It's only been a few hours?

Such a big tree actually appeared out of thin air, how could this make Chen Xi not be surprised?

Although with the help of spells, Chen Xi can also make Qingshan wear red makeup and make all the thousands of maple leaves bloom.

But he absolutely couldn't do it, so that a seedling could become a thousand-year-old tree in an instant.

The bottom diameter of this tree is more than 20 meters, and I don't know how tall the whole tree is.

Chen Xi stood under the tree, tilting his head and looking up, but the thick spiritual mist completely blocked his vision, so much so that he couldn't see the situation above the trunk at all.

Seeing this, Chen Xi took a thoughtful step forward, wanting to touch the bark of this tree.

However, the moment his palm touched the bark......

Sudden change!

An invisible force suddenly surged from all directions, like a hurricane, invisible but extraordinarily powerful.

Chen Xi's reaction was also very fast.

The Tianyan Divine Sword appeared in his hand almost instantly, and immediately followed by a crisp sound of 'bang'.

I thought that there was an enemy attacking, but when Chen Xi turned around with the long sword in his hand, he realized that it was the spiritual mist behind him that had changed in a new way.

Just like the legendary Moses dividing the sea, those thick spiritual mist that even he couldn't blow away were now pushed to the sides by two invisible glass walls, so that a passage appeared out of thin air in front of his eyes.

It was pitch black in the passage.

Seeing this, Chen Xi immediately snapped his fingers.

A ball of light suddenly flew towards the depths of the pitch-black passage.

The passage was not very long, and the ball of light quickly flew to the end.

At this time, Chen Xi also saw the things at the end of the passage clearly.

It was a huge stone monument.

It is not wrong to say that it is a stone tablet, because this stone tablet becomes shiny under the illumination of the light ball, and constantly reflects the unique luster of metal.

The stele is huge, at least ten meters high and two or three meters wide.

On the surface of the stele, there is a line of ancient compilation, which reads:

Ward off evil spirits and seal demons.
