Just as Zhao Yu had been worried about before, the case of the missing exploration team seemed to be in a dead end, with no clues at all.

He read the exploration team’s log a few times but did not find anything suspicious.

There were no torn pages, no traces of editing, and the exploration team’s work had been normal without any accidents.

In order to make sure that there were no problems, Zhao Yu even checked the latest well that the exploration team had opened, but there was nothing in the well, which was consistent with the exploration log.

According to Zhao Yu’s understanding, including the two security guards from tarstan, the twelve exploration team members were all clean and had good backgrounds. They did not have any bad habits, nor had they had any contact with any criminals.

For the past seven days, Zhao Yu had gone to almost every corner near the base. He had also tried a variety of devices, such as a footprint identifier and an invisible tracker, but still found nothing.

As for the suspicious car, Zhao Yu, Bian Dong, and the others watched all the surveillance videos that they could find that day, but they still didn’t find anything suspicious.

It’s really strange!

At that moment, Zhao Yu was sitting in a pickup truck near the base. He looked at the setting sun in the wilderness in the distance, feeling depressed.

He was considering whether he should apply to the higher-ups to transfer his team over to help.

However, he was not optimistic about this proposal. For the past seven days, he had video-called Miao Ying, Zeng ke, and the others almost every day to discuss the case with them.

Although his team members were not by his side, it was no different from working on the spot. Everyone gave Zhao Yu a lot of suggestions, but they were all rejected in the end.

Tsk tsk …

The light of the setting sun shone on Zhao Yu’s face, but he couldn’t feel any warmth. In another ten minutes, darkness would cover the entire wilderness, indicating that another day had passed.

After such a long time, he had been really worried about the safety of the exploration team.

Through the investigation, Zhao Yu was able to clearly understand the family situation of every member of the exploration team. Their relatives, wives, and children, as well as their entire family, were waiting for their safe return.

However, after investigating for so long, he had not found a single clue. He was really ashamed!

Before he came, he had promised Division Chief Jiao, but now, sigh …

While sighing, Zhao Yu suddenly felt a heavy weight in his stomach, and he wanted to relieve himself.

So, he jumped off the pickup truck, turned to the outside of the truck, unbuckled his belt, and was ready to kill them on the spot.

This place was located in the wilderness, so the exploration team naturally did not need to build any toilets. All personal problems were solved in a random place.

Hua Hua …

Maybe it was out of habit, Zhao Yu faced the pickup truck and put all the water on the wheels.

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

The small hole looked very unremarkable, especially when the sun was about to set. If one did not deliberately observe it, one would not notice it at all.

Men were naturally mischievous, and Zhao Yu was no exception. When he saw the small hole, he subconsciously turned the “gun” to the side and poured all his water into the small hole.

However …

After Zhao Yu was done with the “water,” he frowned.

Eh?

That’s not right. I have quite a lot of water, so why isn’t this small hole … Full?

This …

Suddenly, Zhao Yu realized a problem.

This small hole … What was it for?

The ground here was made of solid soil and gravel. It was not an easy task to make a small hole in the ground. At the very least, tools like hammers and awls were needed!

Moreover, he had a lot of water, but it didn’t fill this small hole, which meant that the hole was very deep!

Such a deep hole, it seemed even more difficult to dig, right?

This was …

Zhao Yu looked around in a hurry. The first thought that popped into his mind was that someone must have set up a tent here before, and left it here because of that.

But … The base of the exploration team was right next to them, who would set up a tent here? Was there a need for this?

And …

Zhao Yu took two steps away, but soon had new doubts. If they were setting up a tent, it was impossible to only make one small hole. So, there must be another small hole within a few meters.

However, he did not see any other pothole when he carefully examined the ground nearby.

Eh?

This was strange. This small hole … What was it used for?

Hitching the horse?

No… Shouldn’t they at least find a Leeward place to tie up the horses and animals?

This was a relatively open and spacious area in the exploration team’s base. Was it possible to tie up the animals here and let them drink the Northwest wind?

What … What other reasons could there be?

Just as Zhao Yu was thinking, the sun finally set, and the earth fell into darkness. The small hole under the car was also quickly covered in shadows.

However, Zhao Yu was very interested. Even though he didn’t think that the small hole had anything to do with the case, he was still curious and wanted to know what the small hole was for.

Thinking of this, he called Bian Dong through the walkie-talkie, asking him to bring the local technical personnel over to check. He turned on his invisible flashlight, crawled on the ground, and looked at it up close …

……

Ten minutes later, with the efforts of Bian Dong and a few local police officers, they pushed the pickup truck to the side.

Under the bright light, everyone could see the small hole more clearly.

“Officer Zhao,” Bian Dong pointed to the local police officers and said,”they said that they don’t know what this small hole is for. Should we dig it up and take a look?”

“No…” Zhao Yu waved his hand, then asked with a frown,”is it because of the sandstorm, so they built wooden stakes for the camp?”

“I don’t think so …” Bian Dong muttered.”There are no sandstorms on the tauzi plateau, but there are some strong winds, but …” He pointed to the camp in the distance and said,”the camp is so far away. Even if they were to put wooden stakes here, they shouldn’t be here!”

“Besides, the campsite is full of wooden houses. If we were to tie wooden stakes, they would have to be very thick. This hole is obviously a little small!”

“Right!” Zhao Yu nodded, then said,”it’s windy on the plateau. If such a small hole wasn’t dug recently, it would have been covered by dust and gravel, right?”

“That’s right.” Bian Dong nodded.”That is to say, this small hole was recently made! Did the exploration team play golf or set up some sort of equipment to make this hole?”

“Well, that’s a possibility …” Zhao Yu said.”Well, you guys split up and see if there are any similar small holes!”

“If they are really setting up some kind of equipment, there can’t be only one!”

“Right!” Bian Dong nodded and hurriedly mobilised the police officers to start searching with their flashlights …

In the end, after searching for only a dozen minutes, someone immediately raised their hand, and that person found another hole that was exactly the same as the one that was a dozen meters away …
