Because they had seen Haji's skills once, the officers and soldiers of the Zhouqiao unit did not say anything, and cooperated with the assault boat to row back slowly on the way back, keeping a relatively close distance between the hull and the river bank as much as possible, so that Haji could carefully look for abnormal traces.

Although the assault boat was close to the riverbank, it was even harder for Haji to smell the smell that emanated from the mountain forest. Haji felt that the smell did not come from the riverbank, but from the depths of the forest. Since the assault boat was too close to the river bank at this time, Haji was not on the same plane as the wind blowing in the forest, so there was less chance of smelling that smell.

Captain Liu and the officers and soldiers of the Zhouqiao Force naturally did not know this, and they continued to search along the river bank with their boats, and paid attention to Haji's every move, trying to let Haji find any abnormal clues. Haji also searched nervously, but found nothing for a long time.

Just as Haji was about to give up, he suddenly smelled another smell in his nose, which was not the smoke and stench just now, but the natural smell that only the human body could emit. But this place is close to the inaccessible mountain forest, who would come here? Is it really a missing person? And judging by the smell, there is no strange smell on the person who appeared nearby, as if he was a living person. Could it be that the other party is a survivor?

With this in mind, the assault boat went a short distance downstream, and the smell of people haunting the neighborhood became even more pronounced. Haji even noticed that the man's scent was also stained with the smell of mud and aquatic plants, which proved that the man seemed to have crawled out of the water, and the smell was quite fresh, and it had been less than a day. This means that in this inaccessible mountain forest, the air is very fresh, and there are very few disturbing smells, so that Haji can clearly distinguish this abnormal smell.

At this time, the assault boat was rowing to a place where the river bank was hollow and the current was gentle. Haji looked closely, and the smell of mud and aquatic plants he smelled was coming from this place. The traces of silt and aquatic weeds on the river slope are still new, and they seem to have been formed in the recent past.

Could it be that the other party is really a survivor of a car accident? Otherwise, how could someone have climbed up from the water in such a close period of time? And leave traces? But why didn't this person wait on the shore and call for help after he climbed ashore? Or was he injured? Unable to call for help? No, it was not right that he was injured and unable to call for help? In that case, he should not be able to get out of the place, but how did this person leave?

"Wangwang......" Haji looked at the location with silt and aquatic weeds and let out a warning cry, which immediately attracted the attention of Captain Liu and the others.

"Stop the boat!" Captain Liu and the officers of the Zhouqiao unit gave the order almost at the same time, and then asked the assault boat to get as close to the shore as possible.

That's right, it's a new trail of silt and aquatic weeds, and although the trail has dried up, the aquatic weeds that have never completely dried up can tell that this location was climbed not so long ago.

"It's here! Good Haji!" Captain Liu was very excited, he didn't expect that just as he was about to collect the team and go back, Haji found a second important clue. While that doesn't mean he's going missing, Haji's performance is impressive enough that there's no reason why he shouldn't be excited. He rubbed Haji's head, then took a dried fish from his body and fed it to him. Haji was naturally not polite, and the habits of dogs guided him to smile very happily at Captain Liu's reward.

"Awesome, awesome! What a smart dog!" The officers and men of the Zhouqiao unit were also full of praise for Haji.

After a closer look, the group disembarked from the assault boat with two search and rescue dogs, Haji and Black Panther, and began to search for the suspicious location.

Within ten minutes, Haji and the Panthers had followed the suspicious disembarkation site to a place not far from the shore. The place is backed by a large tree under which dense weeds grow. And now, this large area of weeds has been crushed by people, and it is clear that someone has been sitting here for a while not long ago. Looking into the river from this position, you can see that the assault boat of another group of people and horses on the opposite bank of the river who is organizing rescue is leaving.

Upon closer search, Haji and the Panther found two cigarette butts near the overwhelmed weed, and the smell of the cigarette butts alone showed that the man who stayed here had smoked two cigarettes here half a day ago. It is worth noting that the search and rescue personnel had already started searching for the missing person half a day ago, and if that person had stayed in this position at that time, it is likely that he could have seen the searchers driving over the river with a charge. But this person stayed quietly in the mountains and forests all the time, and did not send any signal for help at all.

Isn't this man missing? If he wasn't, then how did he end up in the river? Could it be that this person is a nearby villager? But according to the local ** official who commanded the search work, this area can be regarded as vast and sparsely populated, and there are no residents in close proximity, so where did this person come from? Even if there are some residents nearby, who would run into this sparsely populated mountain forest and what is he doing?

If the person is one of the missing, then why doesn't the person wait by the river for help, or return to the place where the accident happened on their own. Why did he hide in the mountains and forests, sitting under a tree with a view of the rescuers on the river, but not going out to call for help? Either way, this man was too strange.

Haji is not an ordinary search and rescue dog, so he will naturally suspect the identity of that person, and the other search and rescue dog, the panther, is not so bright. It could only sniff the cigarette butts left by the suspicious person repeatedly, just like a normal search and rescue dog.

With a "poof", the panther choked on the smell of the two cigarette butts and instinctively sneezed. Haji saw the panther sneeze and suddenly came to his senses.

He had just smelled it, and in addition to the usual smell of smoke, there was also an obvious smell of vinegar on the cigarette butt. Haji didn't pay attention to the smell at first, because according to the dog's sense of smell, whether it was the smell of smoke or the sour smell of acetation, it was an obvious irritation to Haji, so he didn't want to smell it for a long time!

What does this vinegar sour smell represent? Haji naturally didn't know. After he came to the search and rescue dog squadron, he was exposed to the training of search and rescue dogs, but if he came into contact with the training of police dogs or drug detection dogs, he would know what this fat acetic acid is - poison = product!

Yes, that vinegar sour smell is the smell of poison, which is why the mysterious man is hiding from the search and rescue team. Although Haji didn't know what the sour taste of fat meat vinegar was, with his clever brain and the mysterious man's behavior of hiding his head and tail, Haji could roughly guess that there was something wrong with this person. But what if you guess that the other party has a problem? Haji can't communicate with Captain Liu and the others in detail, so there's nothing he can do!

Fortunately, after discovering the traces left by this mysterious person, Captain Liu and the officers of the Zhouqiao unit were also a little strange. What the hell did this mysterious man do? He was wet in the water on a rainy night, but he had been hiding in the mountains and forests for half the night and a day, but he did not come to the rescue of the search and rescue personnel who came close. There must be something hidden in this guy, otherwise he wouldn't have adopted such an attitude.

Captain Liu briefly discussed with the officers of the Zhouqiao unit and immediately reported their findings and analysis to the headquarters. The command side groaned for a moment, and then asked the two of them to lead the team to try to search for the mysterious man. At the same time, the command immediately dispatched police personnel to rush here, and they will join the search team as soon as possible. Before the police arrived, the command did not allow Captain Liu and them to enter the mountains and forests without authorization to conduct a search.

It's six o'clock in the evening, and the mountains and forests are already dark, but now it's basically completely nighttime. Under such visual conditions, it is necessary to use lights to supplement the lighting, but once the lights are used, the mysterious person will definitely find out. Judging from the fact that he is hiding from the search personnel everywhere, if the search and rescue personnel rush to get up, there may still be danger!

Soon, four members of the police arrived quickly. The four of them had only one pistol, and the other three carried only a throwing stick and two hastily made wooden sticks. There was no way, several of them were called to maintain order at the scene of a major traffic accident, and there was no corresponding preparation at all. The only police officer with a gun was still the leader on duty, and the gun was also based on the principle of preparedness. Who would have thought that such a thing would come in handy as a result, and it will soon come in handy.

As soon as the police arrived, Captain Liu and the officer of the Zhouqiao unit immediately greeted them and informed the superintendent of the police about what they had discovered. Hearing what Captain Liu and others said, the four policemen quickly unified their opinions and also believed that there was something wrong with this mysterious person.

When they took the two cigarette butts and smelled them, the policeman who had handled drug-related cases at the head judged that this was a cigarette smoked by an addict with spices. In other words, this mysterious person is definitely a drug addict regardless of whether he is the missing person in the car or not, which is why he has been hiding from the search team.

So what's next? Finding this person is the immediate priority. Whether he was the last missing person in the traffic accident or not, just because of his addiction status, the police should not let him go. But it is worth noting that if this person is really a drug addict, then this person is more dangerous, and no one is sure whether he is carrying a weapon or not.
