Blowing off the last layer of dust on the surface, Xie Xiaoshuai moved his body up and down, left and right, observing the ground in front of him from several angles. Pen & Fun & Pavilion www.biquge.info

Probably finding nothing, Xie Xiaoshuai continued to pick up more dirt with his hands and expand the scope of the search.

The first company commander wanted to come forward to help, but Xie Xiaoshuai stretched out his hand to stop them, signaling that they could do it alone.

Centered on the point where the bullet casing was found, Xie Xiaoshuai pouted and lay on the ground and slowly pushed forward, cleaning up the dirt on the surface, and his movements were extremely meticulous.

When he almost opened a one-meter-square circle, Xie Xiaoshuai finally stopped his movements and gently blew away the dust on it.

Five minutes later.

"Let's all come and have a look!" Xie Xiaoshuai slapped the dust on his body and said to the company commanders.

The company commander hurriedly stepped forward, but when they looked at the ground in front of Xie Xiaoshuai, they didn't see anything unusual.

"Battalion commander, forgive me for being clumsy, I really don't see anything." The company commander shook his head and said.

"You're all scattered, and you're blocking the light, so of course you can't see anything." Xie Xiaoshuai pouted and said.

Several people hurriedly moved out of the way and moved their bodies to the backlit side, trying to let the light of the remnant sun shine on the ground in front of them.

Several company commanders still have a lot of battlefield experience, and at a glance, they can see that the ground under Xie Xiaoshuai's feet is a little different from other places, and there seems to be some kind of mark on it.

"Battalion commander, this looks like a footprint, right?" The first company commander was the first to find out what this mark was left behind.

"Yes, it's a footprint, and it's a professional mountain boot." Xie Xiaoshuai said with satisfaction.

The first company commander and several of them all focused their eyes on Xie Xiaoshuai, waiting for his answer.

Although Xie Xiaoshuai is not very old, he has participated in dozens of battles, large and small, and his rich combat experience is by no means comparable to that of a company commander.

This kind of boots is very rare among the people, and most people have never heard of it, let alone seen it.

But in a special group, this kind of boot is very common, and it can even be said that it is a pair of hands.

And the name of this special group is only two words: mercenaries.

The first company commander had never been in contact with the special group of mercenaries before, but they only had a general understanding.

But Xie Xiaoshuai can tell what kind of shoe left this shoe print in one bite, so it means that he must know very well, so they don't dare to express their opinions as soon as the company commander is in charge.

"What are you looking at me for? Say whatever you want. Xie Xiaoshuai glanced at the company commanders.

"Battalion commander, you're saying this is the mountain combat boots that mercenaries are widely equipped with?" The fourth company commander couldn't help it, and took the lead in asking Xie Xiaoshuai.

"That's right, it's indeed the favorite of mercenaries, and it's also the favorite of those private armies abroad." Xie Xiaoshuai replied with a smile.

"Battalion Commander Xie, this can't be, right? Our country is a forbidden place for mercenaries! Wu Yongfei asked incredulously, obviously a little unbelievable of this fact.

"Brigade Wu, there is nothing impossible in this world! Our country is indeed a forbidden place for mercenaries, but there are still some guys who want money and don't want to die, and they sneak into the country and do some shady things. Xie Xiaoshuai said.

"Oh my God, this is terrible, we must go back and report to the Director immediately!" Wu Yongfei said with an anxious look on his face.

Xie Xiaoshuai thought about it, then nodded and said, "It's okay, let's go back and prepare and plan our action plan well." ”

"Battalion Commander Xie, I used to be a scout, and I have a lot of experience in investigating! But there's one thing I haven't figured out, why are you so sure that you can find this footprint? Wu Yongfei never figured out how Xie Xiaoshuai found the footprints.

"It's very simple, although the wind and sand will cover the footprints that were stepped on a moment ago, but it can't erase the traces under the sand! Also, the sand contains some crystals, and the ground here is not very hard. Therefore, when these crystals are stepped on, they are pressed into the dirt by the pattern on the sole, and the shoe prints that have been stepped on here are recorded, so you only need to peel off the dirt to see the shoe prints. However, you must be meticulous in this process, and the slightest carelessness will destroy the clue. Xie Xiaoshuai explained with a smile.

"I understand this reason, but why didn't the investigators in our bureau find this footprint, and you can find it as soon as you come?" Wu Yongfei asked.

"I'm sorry Team Wu, this involves some professional knowledge, I can't reveal it to you, what should you know about the confidentiality rules, right?" Xie Xiaoshuai refused to answer Wu Yongfei's question.

"Okay, since Camp Commander Xie doesn't want to say it, then I won't be strong, let's go back first." Wu Yongfei said very boringly, and then turned around and walked towards the off-road vehicle.

This came and went, plus Xie Xiaoshuai and they stayed for a while, the sun had completely sunk into the horizon, and the sky gradually darkened.

Back at the police camp, Wu Yongfei first took Xie Xiaoshuai to a tent specially built for rattlesnakes, and then went to report the findings to the bureau chief at the scene.

At this time, the temperature was probably close to freezing, Xie Xiaoshuai and the others were shivering from the cold, and after entering the tent, they immediately took out their coats and draped them on their bodies to keep out the cold, which made them feel much more comfortable.

Not long after, several men dressed as chefs walked into the tent carrying two buckets, and a strong smell entered Xie Xiaoshuai's nostrils.

This taste is quite familiar to everyone, it is the unique smell of local goat meat, and it is simply a pleasure to drink a bowl of hot mutton soup on such a cold day.

On this day, Xie Xiaoshuai and the others just ate a meal in the morning, and their stomachs were already protesting at this time.

After receiving the mutton soup sent by the fourth company commander, Xie Xiaoshuai blew a few sips hard, and then took a sip gently.

Suddenly, a hot current ran down Xie Xiaoshuai's throat all the way to his stomach, and there was a feeling of hair follicles opening wide all over his body and wanting to sweat.

With a warm coat and hot mutton soup, Xie Xiaoshuai no longer felt the slightest chill at this time, but felt a little sleepy.

Suddenly, a flash of light flashed in Xie Xiaoshuai's mind, which shocked him suddenly, but he didn't show it.

Walking out of the tent with his coat on, an even colder air came to his face, and a thick layer of frost had solidified on the top of the tent.

At this time, Xie Xiaoshuai was thinking, those guys with livestock may also be helpless, right?
