At this time, Lan Xue'er and Hei Tielie were hiding behind the small hill, cautiously watching the slave prison.

Lin Yu looked around and saw that the prison was surrounded by a wall more than two meters high, which was made of stone blocks and covered with spikes at the top. In the center of the prison stands a watchtower, on which soldiers are lazily observing, and it seems that the defense is lax.

At this time, the weather was supposed to be clear, but dark clouds drifted over. The prison was covered in black blood stains, and it was unknown how long it had been accumulating. On the periphery of the wall, there were piles of seeping bones, and when the breeze blew, the smell of rot shrouded the earth, attracting a large number of flies to "buzz" around.

It is also because of the smell of rot that the guards at the gate of the prison are wearing masks. The smell of decay attracted the most scavenging animals, such as hounds and flies, who were all wandering around, guarding each other with the guards.

From the outside of this prison, it is impossible to observe the situation inside, but just by seeing the scene outside, you can already imagine what kind of life the slaves inside live!

"To be honest," Lan Xue'er said with a frown, "I really want to throw up right now." ”

"Why, Lao Tzu has lived for almost a thousand years, and he has never seen such a tragic place, and the mass graves left by the wars in ancient times are nothing more than that!" Hei Tielie looked at the blood stains and white bones on the wall, spat on his saliva, and said angrily.

Lin Yu was also in a cold sweat at this time, the ugliness of human nature had already made him angry, but he still endured it.

"There are no trees here, and my sensing range is only 50 meters. Lan Xue'er touched the earth with a small hand, sensing the message that Xiaocao helped her transmit, "There is no vegetation in the prison, so I can't sense anything, but, my intuition tells me that there is a dark aura surging behind the prison, this breath is very powerful! ”

Hei Tielie also said: "That's right, that dark aura, it's the first time that Lao Tzu has noticed it when he's grown so big. Boy, use your title deed to see what's going on!"

Lin Yu took out the title deed, silently closed his eyes and sensed, at this time, because it was closer to the prison, the information that could be detected was more detailed, this prison occupied an area about the size of a football field, and there were many slaves in it, about three thousand.

And there are only about fifty people in the human race, and among these more than fifty people, most of them are first-order and second-order strength, only a few are third-order strength, and the strongest is a fourth-order warrior, and two fourth-order magicians.

Moreover, there is indeed a powerful dark force inside, and seeing that the management of this prison is so loose, Lin Yu guessed that this prison is full of traps?

Lin Yu's title deed can check the situation of all creatures in the territory, but he has tried before, he can only detect how many slaves and how many human powerhouses are inside, but he can't do anything about the traps in the prison.

Originally, he also wanted to use soul power to detect, which would be much more accurate, but this prison has a powerful enchantment that envelops the entire prison, and soul power can't penetrate at all. Only by virtue of the title deed can you get a glimpse of some of the circumstances inside, otherwise if it is just Lan Xue'er and Hei Tielie, you will have to be blinded.

Lin Yu took back the title deed, then thought about it for a moment, and said to Lan Xue'er and Hei Tielie: "I haven't detected the situation inside very clearly, so I decided to go in and see it in person first, you can observe outside, and then come in to support if there is a situation." ”

"I'll go with you!" said the old dwarf Black Iron Lie, "there are my dwarven people inside, and I can't just watch from here. ”

Lin Yu persuaded: "If we break in recklessly and fail, then these slaves will never be able to be rescued." So let me go and find out first. ”

Lan Xue'er also echoed: "That's right, this place is very strange, and it really should be cautious." ”

Saying that, Lan Xue'er looked at Lin Yu again, remembering the scene of fighting with him before, not only was he bold and careful, but more importantly, his various magical spiritual costumes made him full of tricks.

Thinking of this, Lan Xue'er felt that it was the best choice for Lin Yu to go to reconnoiter first, and she continued to say to Hei Tielie: "Just let Lin Yu in, his skills are not bad, and he is dressed in a god suit, even if he is discovered, he has the strength to protect himself and exit safely." What's more, Lin Yu is more rational and knows how to make trade-offs, so old man, you are here waiting for his news. ”

"Okay," the old dwarf clutched the storm axe and agreed, in order to be able to better save his people, Hei Tielie knew that he should not be too frontal and learn to use his brain, but for the dwarf, using his brain is obviously a very difficult thing.

But fortunately, at this time, Hei Tielie was surrounded by Lin Yu and Lan Xue'er, one of these two was a human spirit in two lives, and the other was an elf who grew up in a human spirit, both of which were objects that Hei Tielie could negotiate, which made him a lot more stable.

During the time of living and fleeing with the sub-people, there were many times when Hei Tielie would also think that it would be good if there were humans like Lin Yu by his side before, there would be many things to be able to discuss with him, and even when there was about to be a war in the future, Lin Yu would be able to replace himself, and he would not completely fall to Black Iron City as soon as he left, without even a decent resistance.

"Then I'll go first. Seeing that Hei Tielie and Lan Xue'er had agreed to their plan, Lin Yu took out the Light Spirit Boots from the mobile warehouse, although these shoes were only high-grade spirit clothes (blue clothes), but they had the powerful passive skill of walking silently, and then Lin Yu took out a bottle of invisibility potion, with the use of Light Spirit Boots, it was simply the best match for sneaking in.

It was the first time that Hei Tielie had seen Lin Yu take out something from the mobile warehouse at close range, and he asked: "I was very puzzled before, your space storage props are too broad, not only can you put away all the food and seeds in the whole car, but there is still a place for it when it takes up so much space, what kind of space spirit suit can have such an artifact skill?"

Lin Yu just touched the vest on his body, this mobile warehouse has taken up a lot of stains because it has been worn outside, but this vest transformed from a mobile warehouse is quite strong, at least it has always been invulnerable.
