"There's no way ahead, we have to take a detour, the trolls have built a dam in the river!" Lago said breathlessly.

Previously, because the message from the gargoyle in the air was not clear, the thieves had to go ashore in advance and explore the way. It's just that he didn't expect to see a shocking scene, and he didn't care about continuing to investigate, so he hurried back to report the news.

"The trolls built a dam?!" When they heard the news, everyone thought there was something wrong with their ears. It was only when I saw the indescribable wry smile on the thief's face that I realized he wasn't joking.

At this time, nearly two days had passed since everyone rescued the three Illistin in the troll village. It was a rare leisure time for everyone, but now it seems that their luck has run out.

At the beginning, the small stream in which the raft was launched gradually converged to the north with other streams, and it has completely become a large river. According to Mastasia, although the river is not meandering, it is very close to the main waterway.

The river is now more than 30 meters wide and more than 10 meters deep, but the current has become gentler, but it is not as turbulent as the previous small stream. Everyone thought that they would be able to follow the river all the way into the meandering river, so as to completely get rid of the threat of the trolls, but they were stopped by a dam at the last moment.

The construction of a dam on a river channel that is more than 30 meters wide and more than 10 meters deep is definitely not a small measure. Although everyone knows that trolls are not beasts, but also a kind of intelligent race, they never thought that the race that was still in the form of a primitive tribe would build such a big project as a dam, which completely subverted the image of trolls in everyone's minds.

"Let's go, let's take a look!" Qin Lun patted Lago on the shoulder and motioned for him to take him over.

"I'll go too!" Mastasha frowned and followed the two.

As soon as she stood up, Elistin followed without admitting defeat, which made Qin Lun look at it with a headache. Ever since he found out that the highland elves were following Qin Lun, Elistin felt very insecure. As the injuries on his body healed, he unconsciously often competed with Mastasia.

However, as an elven druid, Elistin also had experience in surviving in the wild, so he didn't want to be a burden to a few people, so he had to go with her.

After about thirty minutes of sneaking through the bushes on both sides of the river, the four of them came to a high slope on the shore. Looking down from here, you can see the river scene more than ten kilometers away.

"It's a dam!" Looking at the dam in the distance, which was more than 30 meters wide and more than 10 meters high, Qin Lun and the others also experienced the thieves' previous shock.

"How can this be, trolls actually build dams!" Mastasha muttered in disbelief.

Qin Lun's eyes flickered, and he fell into deep thought, he had already fed back what he saw in front of him to the team channel, so that Hill and Rand could also see it.

The wood-and-stone dam is about three meters thick and is made of square rock, with two layers of neatly arranged wooden piles wrapped around the front and back, like a wall in the heart of wood.

At the waterline of the dam, some of the wooden stakes have been soaked and rotted by the river, but some of the wooden stakes can still be seen with tender green foliage on them, and it is clear that the trolls often renovate the dam.

In addition to the shock brought to them by the dam itself, another scene that the thieves had not observed before also surprised Qin Lun and the others, and at the same time realized why the trolls wanted to build such a dam.

In the upper part of the dam, the trolls relied on a solid platform made of boulders below to build a row of fences resembling a women's wall, with some leather ropes made of monster fur tied to them.

After carefully observing the river, Qin Lun and the four of them suddenly found that this dam was a little unworthy of its name, because the river water flowing down the river had reached here, and many small whirlpools had been generated at the waterline of the dam body, which showed that the water flow was not completely blocked, and it could still leak through.

"I see, the dam built by the trolls is not very neat underneath, and the water can flow through the gap between the boulders and the stakes below the guò." Qin Lun hammered his fist and said with a smile, "Look at those leather ropes that extend all the way underwater, I think there should be something similar to a fishing net or a fish basket underwater. ”

"You're saying the trolls built this dam to get water!"

The remaining three were all thoughtful, if it was before they saw this dam, what Qin Lun said would probably be taken as a joke. But after seeing this dam, they no longer think of trolls as stupid and low-intelligence races.

"The river can get by, but our raft can't!" Lago smiled bitterly and shook his head, "We guess we're going to take a detour, so let's go back and prepare!" ”

"No, wait a minute!" Qin Lun stretched out his hand to grab the thief and shook his head sternly, "We can't just go back like this, we have to go to the front and continue to investigate." ”

Largo only frowned before he understood, "You're worried about the size of this troll village?" ”

"Filar's worries are justified!" Mastasia nodded slowly, "From our past experience, most troll tribes have populations ranging from a few dozen to two hundred. Because the trolls eat a lot of food, the village is too populated, which will affect the surrounding ecological environment, and the guide zhì will not be able to maintain their survival and reproduction in the end.

But this is already the depths of the Troll's Claw Mountains, and humans from the outside know very little about it, and we don't know how big a troll tribe can be sustained by the ecology here. If the size of this village is beyond our common sense, then it will probably occupy a very large area, and it is best to investigate it in advance, so as not to accidentally fall into a siege later. ”

Qin Lun and Mastasya were right, and when the four of them walked a few kilometers forward again, they finally saw the typical stake fence wall of the troll tribe.

However, unlike the troll village they had seen outside Trollclaw, the fence was not only tall and sturdy, but barely visible to the eye, only kilometers long.

Through the few openings in the fence wall, they even observed that there were other, slightly lower fence walls deep inside, which obscured the buildings inside the village, making it difficult to see the exact situation.

"I think we should go up and see again!" Mastasia pointed to a low hill to the right of the fence wall.

This low mountain looked higher than the gentle slopes that Qin Lun and the others passed along the way, and the upper part of the mountain had already exposed rugged and hideous rocks, forming a steep mountain wall.

"Wait here, I'll fly up and see!" After nearly two days of rest, Elistine was eager to try, and after nearly two days of recuperation, her injuries had improved and she was ready to turn into a giant eagle again.

"No, let's climb up, there may be a nest of cockscomb eagles on the low hill, it's too dangerous for you to fly up like this." Qin Lun stretched out his hand to stop Elistin.

Because the situation in front of them was somewhat unexpected, the four of them seemed very cautious. When climbing the mountain, try to choose a shaded side, so as not to be accidentally seen by the trolls below the mountain.

Climbing to a cliff platform near the top of the mountain, they finally got a clear view of the troll tribe at the bottom of the mountain, and suddenly the faces of the four of them became extremely ugly.

The troll tribe that unfolded in front of them spanned both sides of the river, in an elliptical shape, spanning nearly dozens of kilometers from east to west, and more than ten kilometers from north to south. The interior of the building is varied, and it is no longer limited to a kind of stilt house, they even saw a megalithic altar with a circumference of several hundred meters.

There are hundreds of young trolls chasing and playing in the central clearing. This isn't a troll village at all, it's a troll town!

The most amazing thing is that in this troll town, in addition to the creatures like trolls, there is also a giant jackal similar to a wolfdog. These canines with sharp fangs appear to be hunting helpers raised by trolls, and can be seen in the gates and the core of the town.

"I've heard other harpists say before that some trolls keep three-eyed jackals as hunting companions, but I didn't expect it to be true." "There are at least a thousand trolls in this town, and once they find out, we won't be able to escape far with the Three-Eyed Jackal's tracking ability. ”

"Then go around a little farther away, get around this troll town, I don't believe that the canyon is so big, we can't find a gap to slip through." Largo scratched his head and said optimistically.

"Well, you see, what's that?" Elistin suddenly twitched his delicate little nose and looked up at the top of the mountain.

The crowd followed her fingers, and saw a wisp of white smoke rising from the top of the hill not far above them, gathering in the air.

"There's someone up there!" Everyone is excited, this smoke is obviously not owned by nature, but artificially generated.

"Lago, go up and have a look!" Qin Lun raised his chin at the thief, before he knew the situation, he had to rely on Lago's stealth ability, now was not the time to be reckless.

"There are three troll sentinels up there, and they're roasting meat!" After a while, Largo brought back a piece of news that made the four of them break out in a cold sweat.

Even though they realized that these trolls possessed extremely high intelligence, several of them were still a little careless. If it weren't for the laziness of the troll sentinels, or if it weren't for the fact that this time was just the time for them to eat, I'm afraid the actions of several people would have been discovered long ago.

However, the existence of these three troll sentinels also made Lago's mention just now end without a problem. The woods of the Trollclaw Mountains are not dense, and when you look down from the top, the scenery below is clearly visible.

The troll town in front of you covers a huge area, and if the team does make a detour from the bottom of the mountain, it will take at least two or three hours to actually get around. For such a long time, no matter how lazy these troll sentinels are, I'm afraid they will also observe the behavior of the team, and it will be a lot of fun.
