As Zhao Yu was worried before, the disappearance of the exploration team seemed to have really fallen into a dead end and had no clue.

He read the exploration team log several times, but found no suspicious phenomena.

There were no torn pages, and there were no traces of modification. The exploration team's work has always been normal, and no unexpected situations have occurred.

In order to make sure there is no problem, Zhao Yu even personally checked the latest exploration well opened by the exploration team, but the exploration well was empty, which was consistent with the exploration log.

Through Zhao Yu's understanding, including two Talstanese security personnel, the 12 exploration team members are all innocent, have good backgrounds, have no bad habits, and have never had any contact with any illegal people...

Looking at the survey site, in the past seven days, Zhao Yu has traveled almost every corner near the base, and has also tried various props such as footprint identifiers and invisible trackers, but he still found nothing.

As for the suspicious vehicles, Zhao Yu, Bian Dong and others watched all the surveillance videos that could be found nearby that day, but they also found no suspicious signs.

It's strange, it's really!

At this moment, Zhao Yu was sitting on a pickup truck near the base, looking depressedly at the setting sun in the wasteland in the distance, feeling a little disappointed.

He is considering whether he should apply to his superiors and transfer his team to help?

However, he was not optimistic about this proposal. Because in the past seven days, he had to have video calls with Miao Ying, Zeng Ke and others almost every day to discuss the case with them.

Although the team members were not by their side, they were no different from working on the spot. Everyone gave Zhao Yu a lot of suggestions for making contributions, but they were eventually denied...

Tsk tsk...

The afterglow of the sunset reflected on Zhao Yu's face, but Zhao Yu couldn't feel any warmth. In another ten minutes, darkness was about to cover the entire wasteland, indicating that time had passed another day.

After so long, he was really worried about the safety of the exploration team members.

Through investigation, Zhao Yu was able to understand the family situation of each exploration team member, their relatives, wives and children, and the whole family were waiting for their safe return.

But after searching for so long, I couldn’t find any clues. I’m really ashamed!

Before coming, I promised Director Jiao confidently, but now it seems that he is...

While lamenting, Zhao Yu suddenly felt heavy under her abdomen and wanted to put "water".

So he jumped out of the pickup truck, turned to the outside of the pickup truck, unbuttoned his belt, and prepared to solve it on the spot.

This place is located in a wasteland, so of course there is no need for the exploration team to build any toilets. All personal problems are just solved by finding a place.

Wow...

Perhaps due to habit issues, Zhao Yu faced the pickup truck and placed all the water on the wheels of the pickup truck...

However, while he was putting it on, he suddenly saw a small hole in the ground next to the tire.

The small hole looked very inconspicuous, especially when the sun was about to set. If you didn’t observe it deliberately, you wouldn’t notice it at all.

Men all have a natural naughty feeling, and Zhao Yu is no exception. Seeing this small hole, he subconsciously turned the "muzzle" and poured it all into the small hole...

However……

After Zhao Yu finished releasing the "water", his brows frowned unconsciously.

Why?

No, I have a lot of water, why is this small hole not full?

this……

In an instant, Zhao Yu thought about it and suddenly realized a problem:

What is this little hole...for?

The ground here is full of solid earth, stone, and gravel. It is not easy to pestle a small hole on the ground. At least tools such as hammers and awls are needed!

Moreover, I have a lot of water but have not filled this small hole, which means the small hole is very deep!

Such a small hole seems to be even harder to dig, right?

This is……

Zhao Yu hurriedly looked up around. The first thought popped up in his mind was that someone should set up a tent here, which was left behind by setting up a tent.

But... next to it is the exploration team base, who would set up a tent here? Is this necessary?

and……

Zhao Yu took two steps away and soon had new doubts. If he was setting up a tent, it was impossible to just make a small hole, then another small hole would inevitably appear within a few meters nearby.

However, he carefully looked at the nearby ground but did not see any other pits.

Why?

This is strange, what is this little hole used for?

A horse tied up?

No... If you tie a horse and a beast, you should at least find a place to go against the lee?

This is a relatively open and open place in the exploration team base. Are animals tied here to drink the northwest wind?

And...what else is the reason?

While Zhao Yu was thinking about it, the sun finally set, the earth instantly fell into darkness, and the small hole under the car quickly fell into a shadow.

However, Zhao Yu was already intrigued at this time. Although he did not think that this small hole must be related to the case, he was curious and wanted to figure out what this small hole was for?

Thinking of this, he called Bian Dong on the walkie-talkie and asked him to come over with the local technicians to check it out. While turning on his invisible flashlight, he crawled on the ground and looked at it up close...

...

More than ten minutes later, with the efforts of Bian Dong and several local police officers, they pushed the pickup truck aside.

Under the bright light, everyone saw the small hole more clearly.

"Officer Zhao," Bian Dong said, pointing to the local police officer, "they said, they don't know what this small hole is for? Should we dig him open and see?"

"No..." Zhao Yu waved his hand and frowned and asked, "Is it true that because of dust storms, wooden stakes built for the camp, etc."

"No way..." Bian Dong thought, "There are no sandstorms on the Tawuz Plateau, but there will be some strong winds, but..." He pointed to the camp in the distance and said, "The camp is so far away, even if the wooden stakes are tied, it shouldn't be here!

"Besides, the camps are all prefabricated houses. If the wooden stake is tied, it must be very thick wooden stakes. This hole is obviously smaller!"

"Yes!" Zhao Yu nodded and said, "The wind often blows on the plateau. Such a small hole, if it weren't for the recently dug, would have been covered by dust or gravel, right?"

"Yes," Bian Dong nodded, "that is, this small hole is the latest! Is it... the exploration team members played golf, or some equipment to make this hole?"

"Well, there is a possibility..." Zhao Yu ordered, "Let's do it, you can look for it separately to see if there are any similar small holes!

"If there is really something to set up, there is no way there is only one!"

"Yes!" Bian Dong nodded, hurriedly mobilized the police officers, and began to search for them on the spot with flashlights...
