In less than ten minutes, Kurosawa returned and told Yang Xuan all the information he knew.

It turns out that the gems in those slave minecarts are actually "dark crystals", and the demons have the means to process and produce this dark crystals into more advanced "demon crystals"!

Of course, it's not the complete Demon Crystal, but the Demon Crystal fragments. A total of 100 Dark Crystals are required to create a Demon Crystal Shard. Similarly, it takes 100 Demon Crystal Fragments to create a complete Demon Crystal.

Demon crystals have a great attraction to demons, and the most direct effect is to increase the strength of demons, and the more useful ones are unknown. After all, even the demons below who flaunted their might were not qualified to use demon crystals.

An industrial chain has been formed here, and the demon crystals that are finally produced will be sent to the final castle, which is probably where *OSS lives.

……

Yang Xuan glanced at the factory below, there were about 10 demon guards here, and their strength might not be as good as that of the cyclops, but they would never be too different.

And there is only one on Yang Xuan's side, even if you add all the mercenaries, the combat effectiveness is definitely not comparable to the other party! He needs a chance, say...... While the slaves were resting, he went to rescue some ......

You must know that although these slaves are tortured now that they are not human, they must have been the elites of various races before, and if there are many of them, causing chaos, Yang Xuan's opportunity will come.

He found a relatively hidden corner and squatted in ambush. After waiting for a long time, he chatted with his teammates to relieve his boredom.

Originally, when you come to this foggy place, you will be cut off from the outside world. But their previous team was not disbanded, but after everyone dropped the level, they were only level 59 and were not eligible to enter again.

If you want to just chat, you can do it through the team channel.

By the way, he transmitted the video recorded throughout the whole process and passed it to Lu Xiaoxiao by name.

After more than an hour, the demon guard finally blew his whistle, and the slaves were overjoyed and lined up in one direction.

It was a gloomy cave, and compared to the scorching sun outside, it was undoubtedly a good place to be. Outside the cave door, there were also two demonic guards, and the slaves entered the cave one after another, lying down to rest.

Soon after, a demon guard came in with a thick mist, and the fragrant food was covered with a thick black mist, which had the flavor of dark cuisine......

But this is by no means a dark dish, but a "Demon Crystal Fragment" that is contained in every meal, and even the Demon Guards are reluctant to eat it!

Such a seemingly very good treatment made the faces of the slaves present change and show a painful struggle. Demon crystals contain demonic powers, even in fragments! Too much intake will change their characteristics!

As a result, if one day, they are really rescued by their compatriots, and they will definitely not be able to go back. Because at that time, they were no longer like this...... Rather, it is assimilated by demons.

……

It's definitely a big deal. You know, the Demon Crystal Fragment is also a precious material for the Demon. But they generously let these slaves eat, just to cultivate long-term and reliable slaves!

Only one fragment was put in the meal at a time to alleviate the worries of the slaves, and the delicious and delicious meal made some hungry and greedy slaves quickly give up their resistance, like poor frogs, jumping into the boiling warm water.

As soon as someone starts, the hungry door in the stomachs of the remaining slaves will be pushed open. One by one, they were like wolves and tigers, and gradually fell into the abyss from which there would never be any turning back.

Yang Xuan hid in the shadows, frowning when he saw this. He suddenly felt that what he was thinking was too simple, and in the current situation, even if he rescued these slaves, I am afraid that there would not be too many people to help him.

Just when he was at his wit's end, a well-equipped elite regiment appeared on the high platform he had stood on. Wings of Freedom.

"How did they get in?" Yang Xuan's eyelids jumped. This is the interior of the Land of Fog, and if you want to get in, you need to defeat at least a cyclops similar to "Fez"!

Of course, there is also a possibility, that is, the demons can enter, but the elite group of the Wings of Freedom is all demons? This is obviously impossible.

Then there is only the first possibility, and their Wings of Liberty take out a cyclops! Cyclops is anything but scary, and what is truly scary is one of its skills, the Howl.

With this skill, it can summon a large number of demon slimes. I really don't know how Feiyu and the others carried it.

……

As if sensing that someone was observing him, Feiyu turned his head keenly, Yang Xuan happened to be short, and he didn't expose himself.

Although he knew that Exocet and even Wings of Freedom would not deal with him, the two sides were only allies, not true comrades-in-arms. And once he is discovered by the other party, the other party will inevitably invite him to go with him, and it is estimated that most of the credit will have nothing to do with him at that time......

Feiyu retracted his gaze, the corner of his mouth was slightly imperceptible, but it didn't break, but with a wave of his hand, he rushed to kill the brother behind him.

The demon guards resisted hard, but their forces were too scattered at the moment, and they were broken by the Flying Fish and the others, and they were all killed in the blink of an eye.

packed up the spoils, and then Feiyu and the others also discovered the existence of slaves, and the demon crystal fragments they ate were also visible at a glance.

"Flying Fish, what do you think should be done about this?" Tian Yu frowned secretly, and turned to the flying fish on the side and asked.

Flying Fish squatted down, carefully observed the expressions of the slaves, and finally shook his head, and smiled indifferently: "Kill them all." ”

After speaking, the expressions of the slaves changed, they were all nervous before, but now some have become liberated, and some have become hideous, as if they will break through the shackles at any time. In the end, there were still a few people, their expressions remained the same, but they were more nervous.

But Feiyu recorded everyone's expressions one by one, and at this moment, his eyes were sharp, and he couldn't help but say that he separated the three kinds of people.

"Don't kill me, I'm the prince of the vine clan! If you kill me, you will be cursed by the vines! "One of them had a dark face and an awe-inspiring evil spirit. Roaring loudly at the moment, it seems like it will pounce at any moment.

"You're the one who killed." Flying Fish sneered indifferently, and a magic shot condensed on the tip of the wand, easily piercing the man's heart.

Black blood flowed out, producing a scorching black smoke on the ground.

The flying fish stared backwards to avoid touching the filthy blood, and turned his head to stare at everyone: "Do you still have the face to say what kind of prince you are, noble?" Fear to tell you that most of you have become demons! ”
