"Where is this?"

Fengyun climbed up the canopy, brushed aside the branches and leaves, and inspected the situation, and his vision was very good, and he could see far away, but soon his face became ugly.

He found that he had overlooked a very important situation.

Walking along the dark river underground, there is really no need to worry about being discovered by the enemy, which is an advantage, but there are advantages and disadvantages, and disadvantages will destroy his sense of direction.

On a normal day, this is not serious, at most it will take a little more time.

Whether it is with him or with the strength of the soldiers of the expeditionary force, it is unlikely that he will encounter a real threat in the wild, and it will not be too difficult to obtain food, and it is not a big problem to survive for a long time.

But the problem now is that they are in the territory of the cannibal barbarians, and the enemy has known about their existence, and is starting to encircle and intercept them, if they get lost at this time, the consequences will undoubtedly be extremely serious.

Thinking of this, even with Fengyun's current psychological quality, he couldn't help but feel a burst of panic.

"Calm down!

Fengyun took a deep breath and forced himself to calm down.

Maybe this period of grinding has really improved him a lot, and after a while, he really calmed down.

After calming down, Fengyun began to analyze the current situation, and slowly he realized that his situation might not be as bad as he thought.

Although advancing underground along the Dark River did ruin his sense of direction, according to his judgment, he and the Expeditionary Force warriors should still be heading in the direction of the Terran territory.

In other words, as long as he confirms this, even if he doesn't know the current environment, he shouldn't lose his way.

The general direction can be confirmed, and it is sufficient.

As for the reason, it's very simple, as long as they enter the Terran territory, their own safety will be guaranteed, and they will have time to find their way back to Rock City.

"Hoo ......"

Fengyun slowly exhaled a breath of turbid air and began to re-observe the terrain around him, and in order to see more clearly, he urged the Eye of the Serpent God.

After a few moments, his expression became solemn.

He found traces of cannibal barbarians, and the number of them was quite large, probably counted, it should be no less than a thousand.

This means that this is not a safe place, and if the expeditionary force soldiers return from underground to the surface, they may be discovered by the enemy.

Fortunately, he discovered the enemy's whereabouts early, and the expeditionary force soldiers were still in the underground river.

Fengyun began to focus on the cannibal barbarians he had discovered, observing them carefully, hoping to find some useful information from them.

With the help of the Snake God's Vision, although Fengyun was still quite far away from the cannibal barbarians, he could still observe a lot of details.

The cannibal barbarians that Fengyun had found hadn't rushed towards where he was, on the contrary, they were moving away from him, but he was sure that they were looking for something.

As they advanced, they sent out quite a few sentinels, and from the position of Fengyun, it looked like an octopus reaching out with tentacles, bringing a large area of its passage under their control.

If you don't know it, you will break into their warning range, and they will soon find out.

Fengyun observed for a while, and his brows couldn't help but furrow slightly.

He didn't know if it was just this group of cannibal barbarians who adopted this method of searching, or if all the cannibal barbarians had adopted it.

If it's the former, it's not serious, no matter how effective their search method is, as long as they avoid them, no matter how bad it is, find an opportunity to kill them all.

With the strength of the current expeditionary force soldiers, if you want to kill this group of cannibal barbarians, although there are some difficulties, as long as you plan carefully and choose the right time to attack, it should still be possible.

Fengyun is most afraid of the latter, if all the cannibal barbarians adopt this method of searching, whether it is him or the soldiers of the expeditionary force, there will be big trouble.

After observation, Fengyun found that the search method adopted by the group of cannibal barbarians he saw now was actually quite strict.

Although the sentinels they sent out did not communicate with each other, and there were relatively few of them, the connection between the sentinels and the main body of the cannibal barbarians was smooth and continuous.

In other words, if he encounters those sentinels, even if he can catch them before they can find the alarm, or even kill them, he will still reveal his whereabouts.

If the sentry does not take the initiative to contact the cannibal barbarian after the specified time, the cannibal barbarian main body will acquiesce that something has happened to him, and they will move closer to the place where the sentry disappeared.

At the same time, they will also notify the sentinels who have been sent out, so that they can approach the place where the sentinels are missing from all directions, which is equivalent to forming a large net, and it is too difficult to avoid being discovered by them.

Even if you are lucky, if you escape before the cannibal barbarians are encircled, you will still let the enemy confirm your existence, which is still not good for your side, after all, except for the time when you are not very sure, the location and people are on the enemy's side.

The reason why Fengyun knows so much about the search methods of this group of cannibal barbarians is not because Fengyun's reasoning ability is so strong that he can reason about the results just by looking at some details he sees, but because in the process of observing them, he happened to find one thing, which was that their specific operation method was completely presented in front of his eyes.

Not long after Fengyun discovered and kept an eye on the cannibal barbarians, one of the sentinels they sent was confronted.

He suddenly rolled over and fell, and was never able to stand up again, Fengyun didn't know why.

After he urged the Eye of the Serpent God, although his eyesight increased greatly, he was quite far away from the target after all, and his vision would also be blocked, so it was impossible to see the target's every move.

However, Wind and Rain didn't need to know exactly why the cannibal barbarian had fallen, he just needed to confirm the reaction from it.

Less than five minutes later, the main body of the cannibal barbarian realized that something was wrong and sent people to move closer to the fallen cannibal barbarian.

Immediately afterwards, the other sentries seemed to know and rushed over.

But in the process, they spread out, like a big net, and looked for it.

At this time, the sentry really lost contact with the cannibal barbarians because of the outsiders, and the outsiders did not retreat in time, or the speed was not fast enough, and the possibility of being discovered in the end was still quite high.

Of course, there must be some other reason why the communication between the cannibal barbarians and the sentinels sent out would be so efficient, but it didn't matter to Fengyun, he just had to confirm their level of danger.
