Qian Donglu had spent some time in a military dog training base before, and he knew very well how important the nasal mucosa of canines was to the olfactory role of dogs. At the same time, this nasal mucosa is very fragile, so military dog handlers have an iron rule that they are absolutely not allowed to touch the tip of the nose of military dogs unless medically necessary.

But Lin Song's current actions have already made a big taboo, and he wanted to step forward to remind him, but was stopped by Wu Meng and Zhang Feiyu.

Wu Meng said in a low voice: "The boss has to talk to the snow wolf, don't disturb them." ”

At that time, Lin Song raised his head, with a trace of doubt between his eyebrows: "No, it doesn't make sense." Could it be that the snow wolf is taking the wrong way? ”

Wu Meng slowly leaned in: "Boss, what's wrong?" How could a snow wolf take the wrong path? A snow wolf can hold up half a reconnaissance squad. ”

Lin Song took two steps forward, slowly squatted down, and thought about it.

In fact, not long ago, the snow wolf was going to take them and walk towards the left front. But at this time, Lin Song found that there seemed to be some unusual traces left on the ground here.

Mountain warfare requires a high level of experience from the participants. If an excellent soldier with perfect marks in a regular training subject lacks experience in mountain warfare, then his combat effectiveness in the mountains and forests is even inferior to that of an experienced mountain man.

As a matter of fact, in mountain warfare, many things need to be tempered by actual combat, and these things cannot be learned on the training ground.

In terms of this performance, ordinary warriors are likely to be superstitious about Snow Wolf's supreme pursuit ability, but they may ignore some important and hidden factors.

Lin Song found that although the snow wolf was going to lead them to the left front, it seemed from the direction of the broken branches of the bushes here, as well as the direction of the moss on the ground and the grass buds that fell, and the extent of the destruction. The people who passed by here just now were definitely not just the pink-faced fox and a few soldiers under his command.

In this way, the pink-faced fox should have met a group of accomplices here, and then the two groups went their separate ways. The pink-faced fox walked to the left front, so the snow wolf chased after the left front. From this point of view, Snow Wolf made the right choice.

It's just that Lin Song found that on another road, there was a sour breath that would cause slight irritation to the nasal cavity at the moment.

That's right, this is the taste of glacial acetic acid, which is an important ingredient for extracting derived drugs after mixing with morphine and other drugs! And there is only one destination for transporting raw materials, and that is the drug factory!

Lin Song's brain was running rapidly, and in his own conscious world, he restored the situation at that time.

The pink-faced fox led the team to hurry quickly, ready to rush to the drug factory to assist in the defense. But here, they met a team of drug dealers transporting drug raw materials, and after a brief exchange between the two sides, for some unknown reason, the pink-faced fox and his party changed the direction of their march.

Lin Song raised his hand and pointed to the front right: "This way!" ”

After speaking, Lin Song squatted down, gently scratched his hand on the snow wolf's back, his lips closed one by one, as if telling something, and soon, the snow wolf ran towards the right front, while Lin Song and the others continued to line up in a diamond-shaped team, following closely behind.

After about half an hour, everyone found that there was no road ahead, and if they continued to move forward, it would be a cliff. However, when everyone was attached to the edge of the cliff and looked around, they were shocked to find that this cliff was actually a basin strictly speaking.

This basin is approximately circular, with a drop of about ten meters from the surrounding topography. The diameter of the basin is about one kilometer, and from the topography, it is very likely that it is a natural pit.

On both sides of the pit, there is a lift fixed to the rock wall, driven by a steel cable, as a means of transportation from the basin to the ground above.

In this circular pit with a diameter of about one kilometer, the houses are like houses, and the people inside are working in an orderly manner. Many of the chimneys on the houses are emitting white, sour smoke. Lin Song knew that they were boiling the poppy fruit, ready to be further purified.

Around these smoky houses, there was a three-step sentry and a five-step sentry, and near the edge, there was a circle of watchtowers, visible to the naked eye, on which the heavy machine guns on the watchtowers were well-maintained, oil-smeared parts, glittering in the sun. It's daunting.

It can be seen that the person who arranged this drug factory is a professional security expert, and the firepower network composed of these heavy machine guns is impenetrable. In addition, they can also provide cross-support to each other.

In addition, on both sides of the basin, a valley-like channel several meters wide was dug by hand, and a channel was dug from the distant river to divert the river water.

This man-made river, which is about five or six meters wide, also causes the man-made river to flow through the basin extremely turbulently because of the strong upstream water.

At the river inlet, about 200 meters above and below the outlet, there are red and blue signs, the front end is the water intake, and the back end is the discharge point.

In addition to supplying a large amount of water to the drug factory, the turbulent water flow also easily solved the problem of sewage and waste here.

Lin Song couldn't help but say, "The guy who designed this drug factory must be a genius of crime. ”

Qian Donglu put his hand on the trigger retainer: "Brother, just the four of us, if you want to break through this line of defense, I'm afraid it's a little difficult." ”

Lin Song frowned slightly, looked back and forth, and suddenly made a gesture and led everyone back to the bushes not far behind him. Not long after, everyone saw a group of armed men wearing camouflage uniforms and armed with ammunition walking over.

"It's the guards of the drug factory. Around the basin, in addition to watchtowers, there are also patrol posts. Be careful, for a moment we'll evade the patrol and sneak into the drug factory beneath the basin. Lin Song lowered his voice and said.

As soon as the words fell, in the patrol post where the team had already walked, suddenly there was a dog barking!

That's right, it's the voice of a military dog! In this patrol post, there is a military dog! The armed men of the patrol post immediately became alert, and suddenly, these people raised their guns at the same time, aimed them at the bushes, and shouted: "What person? Damn it! Come out! Otherwise, we'll shoot! ”

Everyone was in distress, Lin Song frowned slightly, gently patted the shoulders of the two people behind him, and pointed to the bows and arrows on their shoulders with his eyes.
