There is nothing in the front and back that has anything to do with the earthen wall, so why is there an earthen wall several kilometers long on the grassland? Fan Wu was puzzled.

Descending over the earthen wall to the ground, Fan Wu could still feel that the vibration was still coming, but there was nothing in front of him, where did the vibration come from?

After a moment of calm, I felt that the vibration was still coming from the front, just as I had felt before when I had not seen the earthen wall, and the source was still far away.

At this time, what you see in your eyes and the feeling in your perception are in tune again, and there is no longer that sense of disparity.

Fan Wu slowly retreated until his back was attached to the earthen wall behind him, the earthen wall was real, but when he crossed over to this side, the earthen wall became ordinary, and it seemed to have lost all kinds of abnormalities before.

When he was still on the other side of the earthen wall, Fan Wu always felt that this side of the earthen wall was a town or something, although there were no buildings higher than the earthen wall to be revealed, but that feeling Fan Wu believed that he could not be mistaken.

But after coming over, there was such a scene, which was the result of his never expectation, and the feeling of leaning against the earthen wall told him that it was just an ordinary wall abandoned on the grassland, and there was no town at all.

This feeling also felt quite natural to him, and there was nothing abrupt, and the difference between the front and back was the biggest problem that puzzled Fan Wu.

It's just a wall, how can it feel completely different?

He tried to go back to the other side of the earthen wall again, but he no longer had the same feeling as before, and now he felt that it was just an ordinary earthen wall.

This passive feeling made Fan Wu very uncomfortable, as if he was being deceived, Fan Wu suddenly punched the earthen wall, and with a bang, it just stirred up a little dirt chips, and it was not as fragile as he imagined that he would fall down with a push.

Sure enough, there was a problem, it seemed that it was just an ordinary earth wall made of rammed earth, which should not be able to withstand Fan Wu's attack, but this wall that gave people a dilapidated feeling was almost unscathed against Fan Wu's fist.

This is a completely unreasonable thing, after all, although Fan Wu is only in the state of the conscious body now, but with the help of the subconscious, he has evolved all the way for such a long time, and there is no difference between the strength of the real physical body, and it is even much stronger than the ordinary physical body.

If it was just an ordinary dirt wall, it would not have been able to resist his fist attack, but now not only did it easily resist the attack, but it didn't seem to have taken any damage.

Fan Wu pondered for a moment and punched the same place again, although there was still only a little debris flying out of the place where he was hit by the fist, but a few traces of electricity burst out at the place where it came into contact with the fist.

Fan Wu contained a little thunder and lightning power in his fist this time, so although the earth wall still didn't suffer much damage, it was shaken by the fist.

It's still a bit effective, and although it's still far from damaging the wall, it can cause vibration, which means that the wall is not a non-destructive setting, but the blow is not strong enough.

This also reassured Fan Wu a little, what he was most worried about was that he didn't know when he fell into a formation, since the earthen wall could be destroyed, according to the feeling of feedback back, he was sure that he was not in some illusion.

It wasn't easy to do with the formation illusion, and Fan Wu didn't continue to destroy the wall, because it didn't make any sense, he crossed the earthen wall again and continued to move forward.

There was an endless grassland in front of him, until the earthen wall behind him disappeared from sight, and Fan Wu was once again in the vast grassland.

At this time, a familiar feeling came back to him, the same feeling he had felt before he encountered the earthen wall, and he felt a vibration in front of him again.

Although the vibration never stopped, the frequency of the vibration changed many times, until he saw a touch of earthy yellow in the distance again in his eyes, and the vibration changed back to the previous frequency.

As he walked forward, everything seemed to be repeated, everything he had seen and felt before happened again, and Fan Wu felt as if he was watching a movie or video repeatedly, going through the previous process again.

It's just that this time there is no need to smash the wall with his fist, because he found that there is no need for this at all, although the two experiences look exactly the same, but Fan Wu can tell that the two walls are not the same.

At this time, his original cultivation ability to analyze all things came into play, and when he felt the internal structure of the earthen wall, he immediately knew that although the two walls looked exactly the same, the soil inside was not the same.

The second wall was a little fresher than the dirt in the previous wall, although the difference was not very big, it might be only three to five days, but Fan Wu was able to distinguish this subtle place.

Since the two walls were different, no matter how similar the other factors were, Fan Wu would not be confused, so he didn't have any trouble here on the second wall at all, and he didn't have any stops.

It was only when he crossed the second wall that he found something different from the first wall, the back of this wall was not as dilapidated as the previous wall.

Although it still looks so dilapidated on the surface, it is because it should have existed for a long time, so it has the same sense of dilapidation.

However, the wall is not as broken as the first wall, although it is also a broken wall, but it feels a little better than the previous wall.

And the grass behind this wall is also a little more complete than the previous grass, although the grass that Fan Wu passed through before is also quite rich, but from the feeling from the bottom of his feet, you can know that the ground is actually a lot of potholes, but it has been filled in by the grass.

The ground behind the second wall still has many potholes, but overall it is slightly better than the previous ground, and the potholes are not as dense.

Fan Wu didn't know what caused this, but he could clearly sense that as he continued deeper into the grassland, the damage seemed to be getting milder and lighter.

After some distance, Fan Wu saw the third wall, which was still earthy yellow from a distance, but when he got closer, he found that it was different from the previous two earthen walls, this wall had a lot of sand and gravel mixed in the yellow mud.

On the surface, it looks like a mud wall, but because it is mixed with a lot of sand and gravel, the hardness is incomparable to that of the first two walls.

However, because of the sand and gravel, the wall is not as smooth as before, and there are many bumps and bumps on it, which looks a little rougher.

Moreover, this wall is also about half a meter higher than the previous two, and the grass behind it is more complete, and there are hardly too many potholes.

Although it looks the same on the surface, the feeling of stepping on it is too bad, and there is almost no place for feet on the grass here.

Fan Wu crossed the high wall of mud and sand, and the vibration he felt when he walked on the flat ground was even more obvious.

Almost every time I approached the wall, I felt a vibration not far behind the wall, but after I got over the wall, there was nothing.

Even though Fan Wu had advanced a long distance, crossing three walls, he still felt the tremors coming from a long way ahead.

This was still the case after crossing the third wall, but because the ground was much smoother, the perception of the vibrations was a little clearer, and this time it seemed that the vibrations did not come from stomping on the ground, but rather a bit like the sound of a knock.

Because the frequency of the vibration is not the rhythm that the creature should be stepping on, there is a pause between the vibration and the vibration, if it is not a jumping pedaling, it must be the rhythm of the percussion.

However, it is unlikely that a creature will maintain such a long jump, not to mention physical problems, and it is too boring, so Fan Wu is more inclined to think that this is a tapping.

But who's going to be banging on the ground for nothing?

Fan Wu continued to move forward with such doubts, he didn't have much curiosity about the walls now, after all, he had already passed through three walls, and he believed that there should be more walls waiting in front of him.

Sure enough, for a long time, Fan Wu passed through three walls again before finally leaving the meadow range.

As he passed through the three walls, he found that the materials used in the walls were increasing, and the walls were getting stronger and stronger, until by the time of the sixth wall, they had become mostly sandstone structures, and the earth was only used for adherence.

Although it still looks earthy yellow, it can actually be called a stone wall, and although it is not made of stone blocks, it should not be much harder and stronger.

Fan Wu tried to punch harder, not even the chips, and according to his analysis, this wall is already much fresher than the first wall, although it is still a product of the same age, but the difference in construction time should be more than ten years.

In addition to the difference in the walls, the grass behind it is getting smoother, and the grass between the fifth and sixth walls has barely suffered any damage.

When he crossed the sixth stone wall, he saw that there was no grass behind him, but a body of water, and the endless water seemed to be as wide as the sea, but Fan Wu decided that it was definitely not the sea.

Because the current of the water is fixed from left to right, there is no big wind and wave in the middle, except for a little microwave, the water surface is calm and a little scary.

It stands to reason that such a wide body of water, whether it is the sea or a large lake, as long as there is wind, there should not be no waves, the space here is very empty, and the wind is not small, but the water surface is a strange calm.

Fan Wu stood on the side and observed carefully, and found something that shocked him even more, the microwaves on the water surface were not caused by the wind.
