The Xuanming City he saw today was not yesterday's Xuanming City, and the doubts in his heart made Wang Xu uneasy.

If so, it means that the ghost can make adjustments accordingly, with a certain degree of freedom, and even has a concept of time.

If not, it means that not only will the Xuan Netherworld appear randomly, but the time inside is also random, and it is likely that every day in it corresponds to a day that really happened.

With this doubt in mind, Wang Xu decided to go deep into the danger and enter the Xuanyin City to find out.

Pretending that no one was around, Wang Xu walked in the direction of the city gate, observing the color of the captain.

The captain saw him and did not react, as if he could not see the wilderness outside and still thought he was guarding the city gates.

After passing the city gate, Wang Xu continued to walk inside, the vendors were still those vendors, but it seemed that these people were younger.

"Let's go, hurry up and keep up, let's go play hide and seek!"

A group of children ran past him and ran towards a large locust tree.

Wang Xu's eyes were different, there was a little guy with a runny nose in the crowd, wasn't it the little boy who tried to talk to him yesterday and was dragged away by his partners.

Compared to yesterday, the little boy has become significantly smaller, and if yesterday's little boy was six or seven years old, today's little boy is only five or six years old at most.

In adults, the gap between one or two years old is not obvious, and in children, one or two years younger can be at least half a head shorter.

"The time is really wrong, the time here is at least half a year earlier than yesterday, it seems that this random appearance of the Xuanming City, the time in it is also random."

The more Wang Xu looked, the more certain he was of this concept, but it was a pity that there was no such thing as measuring time in Xuanming City, so he couldn't clearly determine the exact time.

"No, yesterday's Xuanming City disappeared, what happened to the sick man who stayed in the city?" Wang Xu suddenly thought of the sick man who was captured by the Xuan Ming Army.

The sick man is not a ghost, the ghost snake disappeared, he was left in place, or was he assimilated by the ghost snake.

If the ghost snake can be assimilated, and there is no one who leaves the ghost snake before dawn, then he must not stay in the ghost snake for the night.

Thinking of this, Wang Xu hurried out of the city and rushed to the location of Xuanming City last night.

Hurry up, at ten o'clock at noon, Wang Xu finally arrived.

In the eye, in the location of Xuanming City last night, there was only yellow sand, and there were no traces of people.

"Sure enough, it's not there!"

Wang Xu stood in mid-air, looked around, and found no traces left by the sick man.

If the sick man is left behind when the ghost is transferred, even if he doesn't wait here, he will at least leave a conspicuous trace that he can see.

There is nothing, indicating that the sick man is likely to be killed.

Or be killed by the Xuan Ming Army, or be assimilated into a ghost slave by the ghosts, and the chances of surviving are very small.

Of course, just because it's small doesn't mean you don't have any chances.

There is also a small chance that the sick man was taken away by the disappeared ghost and hid in a corner of Xuan Netherworld.

Glancing at the long yellow sand, Wang Xu turned around and left, flying back to the location of today's Xuanming City.

Before it got dark, Wang Xu rushed to the brightly lit Xuanming City, and from a distance, it looked like a real city.

It was already dark, Wang Xu didn't dare to rush in, but hundreds of miles away from the scene, looking at the city with a scrutinizing gaze.

As for how the sick man is, it's not what he cares about now, if the sick man is lucky enough, he may not be dead yet, and if he is unlucky, then don't say anything.

The top priority is not to find the sick man, but to find out the rules of the operation of the Xuanyin City, and he will not venture into it again until he finds out when the Xuanyin City will disappear and when it will appear.

......

There is no sun in the Xuanming Heaven, but there is a difference between day and night, and the brightness of the sky is constantly adjusted with the passage of time.

When it's dark, it's night.

When it is almost dawn, the sky will gradually light up, just like the sensor lights, which is very mysterious.

Wang Xu sat outside the city, letting time pass.

After dark, the city of Xuan Ming entered the night, and as the white light began to appear on the horizon, the city began to melt under the light like ice and snow.

It is like a mirage, from the real to the unreal, and from the unreal to the real somewhere.

Wang Xu watched quietly, and finally summed up the location of Xuanming City, which changed from day to day, and the time was also constantly changing.

The people in Xuan Netherworld City, each performing their own duties, will react accordingly according to their own personalities, and they seem to be the same as normal people.

The only difference is that they will ignore the outside world, such as the captain guarding the door, they will ignore the desert outside, if they were normal people, they would have noticed that something was wrong, but they did not react to it.

Another point is that there are no timekeeping tools in Xuan Netherworld.

This should not be, a complete city must contain timekeeping tools, and there is nothing obviously abnormal here.

Maybe time is contrary to some kind of law of Xuanming City, no, Xuanming Ghost Snake, so it has caused this lack of this.

The sky was getting brighter and brighter, and in the end, Xuanming City came to naught, disappearing without a trace in front of Wang Xu.

Wang Xu knew that Xuanming City was gone, and after disappearing, he went to another place, and that was the beginning of another day.

After the Xuanming City completely disappeared, Wang Xu also embarked on a journey, on the one hand, to find the location of the new Xuanming City, and on the other hand, to see how big the world was.

Perhaps, the emperor's tomb has nothing to do with Xuanming City, it is placed in a corner of the world, Wang Xu comforted himself so much.

For three days in a row, Wang Xu never encountered Xuanming City again, nor did he go to the end of the world.

He was not surprised by this, the real Xuanming Heaven was not necessarily smaller than the Tianwu Continent, even if the Xuanming Heaven was now dilapidated, and the emaciated camel was bigger than the horse, how could it not be too small.

Time passed, and on the afternoon of the seventh day, Wang Xu still hadn't found Xuanyin City, but he had reached the end of the world.

At the end of the world, there is a chaotic storm, and this kind of storm emperor will have a headache when he comes, and he is not even qualified to enter below the seventh order.

Wang Xu was also unable to enter, so he could only turn around.

A month later, he still hadn't encountered Xuan Ming City, but the general scope of Xuan Ming Tian had already been figured out by him.

The ruined Xuanming Heaven is about one-third the size of the Eastern Regions, and there is no grass, only a long stretch of yellow sand, and there are no living beings.

On the 35th day of entering the Xuanming Heaven, Wang Xu, who was wandering, faintly noticed that something was wrong.

Before entering the Xuan Ming Heaven, he had made an agreement with the Wuge Ancestor that if it went well, he would return within a month.

Now, the one-month period has arrived, and seeing that he hasn't gone back, the First Demon Sect should have sent additional manpower.

After a few days, he didn't find anything, as if the sect hadn't sent people here at all.

What's going on, could it be that the Holy Land of the Central Domain has discovered the secrets in the White Egret Academy Palace and restrained the power of the First Demon Sect?

It shouldn't be, even if the secret of the Egret Academy Palace is exposed, and the outside world has been blocked by the Central Domain Holy Land, why haven't I seen anyone from the Central Domain Holy Land in the Xuan Ming Heaven.

On the 37th day, more than a month apart, Wang Xu encountered Xuanming City again.

Now there are two problems in front of him, one is to continue to explore Xuanyin City to find the location of the emperor's tomb, and the other is to rise to the sky and break through the world film to return to the surface.

After hesitating for a long time, Wang Xu was still unwilling to return like this, he was now in Baoshan, how could he return empty-handed.

In case, the top is really blocked by the Holy Land of the Central Domain, wouldn't he work hard to press the gold thread every year and make wedding dresses for others?

Moreover, the power of the First Demon Sect did not come as scheduled, which may not be the reason above.

In some worlds, the flow of time itself is very fast, and there are also worlds with high flow rates of 1:100 and 1:10000.

For example, in the Devouring Starry Sky World, there is a cultivation tower with a time flow rate of up to 1:10,000.

In this 10,000 years, the outside world is only one year, and it is a treasure land for cultivating supernatural powers.

I haven't seen this kind of place in the Tianwu world, because the Tianwu world lacks the law of immortality, and the emperor doesn't dare to cultivate like this, otherwise under the high flow rate world, without the corresponding longevity as support, the faster the time flow speed, the faster he will die.

But in the mythical era when the law of immortality has not yet been extinguished, high-level monks do not need to worry about longevity, and the concept of time there may not be 1:1.
