Some Yadan landforms look like ancient castles, and when the wind blows through these places with strange terrain, it will make all kinds of strange sounds, so some people call it the devil's.

What Wu Ze and Jiang Yan are now facing is this kind of Yadan group, which is known as the Devil's City, which stretches for several kilometers and looks like a huge ancient castle ruins.

The mounds in this Yadan landform group are of different heights, row upon row, looking from a distance, like rows of buildings, and those criss-crossing wind-eroded valleys, but like streets, these masterpieces of nature, just like the artificial buildings designed by ingenious designers, make people unable to distinguish between true and false.

Wu Ze drove the car and slowly walked along the side of the Yadan group, Jiang Yan opened the car window, stuck her head out of the car, and a pair of eyes were like radars, scanning around to see if there were any traces of Luo Fatzi's activities around.

Suddenly, Jiang Yan found that there were some footprints not far in front of her, which extended from the Gobi Desert to the Yadan group, Jiang Yan hurriedly told Wu Ze to stop, opened the car door and ran directly to those footprints.

"Wu Ze, come here, these footprints should be left by the fat man and Meizi." Jiang Yan shouted excitedly at Wu Ze.

Wu Ze walked over to take a look, and saw two lines of footprints on the ground, one large and one small, obviously left by two people, one of the footprints was relatively large, Wu Ze compared it, this footprint is about the same size as Luo Fatzi's foot, obviously, this is what he and Liu Rumei left.

"These footprints are indeed left by the fat man and Meizi, it seems that they walked into this Yadan group." Wu Ze said after careful observation.

"Fatty, plum, are you there?" Jiang Yan couldn't wait to tear open her throat and shouted.

It's a pity that they didn't hear the responses of Luo Fatzi and Liu Rumei, and the only thing that responded to her was the whining wind blowing from the Yadan group.

Wu Ze also shouted a few words, but he also did not respond at all.

The sky had gradually darkened, darkness was about to come, and the wind on the Gobi Desert was gradually getting stronger, and their current position was just downwind, and the strong wind blowing from a distance blew away their shouts.

"Wu Ze, it doesn't seem like we're shouting like this." Jiang Yan said with some frustration.

"Well, it's useless to just call it that, so let's go inside and look for it." Wu Ze replied.

At this time, the sky was completely dark, and they couldn't even see the Yadan group in the vicinity very clearly, these abrupt mounds of different heights, under the cover of night, could only faintly see heavy black shadows, which looked very weird.

Because the ravines in this Yadan group are staggered and uneven, and the distance between the mounds varies widely, it may be difficult to enter and exit some places if you drive in.

Wu Ze's head turned, it was not very convenient to drive in, so he simply put the off-road vehicle here and walked in directly to find it.

So the two of them took out a flashlight from the trunk of the off-road vehicle, put on their backpacks, and copied a sapper shovel in their hands, and then followed the footprints left by Luo Fatzi and the two to walk towards the Yadan group.

"Wu Ze, do you think the two of them will encounter any danger?" Jiang Yan was always a little uneasy in her heart.

"Jiren have their own natural appearance, they should be fine." Wu Ze said calmly.

Although Wu Ze didn't know the bottom in his heart, he didn't want to mess up first.

It stands to reason that this place is on the edge of the Gobi Desert, there should be no fierce beasts, and it is impossible for the two of them to encounter any danger.

"Hey, there are no footprints ahead." Jiang Yan was surprised.

There was some yellow sand piled up in the ravine just now, and people would leave footprints after stepping on it, and now they were about to walk out of that ravine, and the front was already hard ground, so the footprints left by Luo Fatzi and Liu Rumei had disappeared.

Wu Ze's heart suddenly disappeared, which meant the loss of the most intuitive clue, which would undoubtedly bring trouble to the two of them.

Wu Ze looked up, in this Yadan group, the mounds and ravines are criss-crossed, if there is no footsteps as a guide, in this black light blind situation, it is undoubtedly very difficult to find Luo Fatzi's whereabouts.

These mounds and ravines in the Yadan group have turned this place into a labyrinth, and at a glance, it is impossible to distinguish the ins and outs.

"Will they get lost in this Yadan group?" Jiang Yan looked at the complex geomorphological environment in front of her and asked Wu Ze.

Wu Ze pondered for a moment and nodded, "This is possible."

There is indeed this possibility, if you enter this place with complex terrain, if you go too deep, it is very likely that you will not be able to distinguish the direction of the surroundings, and the possibility of getting lost in this place is still very large.

"The fat guy is really, if you want to pick up stones, you can pick them up on the Gobi Desert, why do you have to come here, this black light is blind, where can we find them?" Jiang Yan complained as she walked.

After they continued to walk forward for more than a hundred meters, the footsteps of both men involuntarily stopped, because three forks in the road appeared in front of them.

The ditch had come to an end, and in front of them were three roughly shaped furrows, each stretching forward in a zigzag way, and they didn't know where it led.

Wu Ze and Jiang Yan stood at this fork in the road, and it was a little difficult to choose which way to go? They all began to hesitate.

"Wu Ze, look, there's a mark there." Jiang Yan pointed to the dirt wall of the trench on the right.

The headlamp on Wu Ze's head swept the mark on the earthen wall, and he immediately knew that this mark was left by Luo Fatzi, because this kind of mark was often used by the two of them.

"That's right, this mark was left by the fat man, let's go to the right, the fat man should go from here." After Wu Ze saw this mark, his heart calmed down a little.

With the guidance of this mark, they found the traces of Luo Fatzi and their passing again, and the two of them walked along this ditch, and in the middle of this ditch there was a section of yellow sand deposits, and found the footprints of Luo Fatzi and the two of them, this time, it is even more certain that Luo Fatzi has walked from here.

Seeing these footprints of different shades on the ground, Wu Ze and the others were in high spirits, and the speed of walking under their feet also accelerated a little.

Ten minutes later, this ditch hundreds of meters long has been walked to the end by them, and they have not found the whereabouts of Luo Fatzi, and as the yellow sand on the ground slowly decreases, the footprints left by Luo Fatzi have also disappeared.
