Following the man, he walked towards the huge cavern, and as he stepped inside, the smell of blood became stronger and stronger, and the sound of ticking and falling water droplets spread through the cave.

Inside was a huge pit, with stone steps spiraling down the walls, and from above, it was a pitch-black abyss, but from above, there were chains hanging down, and on each chain were hooked corpses, monsters, human bodies, and monsters that looked like people.

Poof!

The torches on the rock wall suddenly brightened and stretched all the way down, illuminating the steps and the surrounding walls.

The man in the lead walked cautiously, not daring to make a big movement, and then said softly: "Be quiet, don't make a sound." ”

Lin Fan felt that this place was very weird, but for him, the weirder it was, the better, at least it could show that there would be unexpected good things.

The man was genuinely afraid of this place in his heart, but he was also relieved to think that he would be able to return to the sect in a few days and change shifts.

This place is really more demonic than the Demon Land, especially the Great Demon Master is even more terrifying, and even gives him one, if necessary, the Great Demon Master will not hesitate to put him there for experiments.

For this guy who applied for the job, he can only say that he hopes you can hold on for three days.

After all, since history, people who can last for three days are very rare, and at most they only live for seven days.

All the way to the abyss, surrounded by passages in all directions, and in each passage, there were roars, the sounds of which were like the voices of wild beasts and human beings.

Lin Fan was not shocked, but he felt it, and the man in the lead trembled, as if he was very afraid of this place.

At this time, two people came in front of them, and these two people were dragging a corpse in their hands, but when they got closer, they found that half of the corpse's face was a hideous beast face, and the sharp beast teeth bulged out, which was very terrifying.

It's just that there is no breath and it is clearly dead.

"Come with me, you'll see this a lot in the future, but even if you're scared now, it's too late. The man said.

Lin Fan smiled and didn't say anything.

Then he walked towards a passage, walked for a while, and pushed an iron door open, and the sound of beasts inside became even more violent, and there was even the sound of chains colliding.

"Lord Demon Master, the assistant who applied for the job is here. The man said respectfully, looking at the huge phantom imprinted on the wall, which was obviously a demon beast hanging there, but suddenly it was torn apart.

"Useless things, these forces can't hold up. A gloomy voice came from within, obviously a failed experiment, very angry.

When the man heard this, he trembled even more, and cold sweat broke out all over his body

"yes, my assistant is here, so I really need to take a good look. Footsteps were heard.

In the man's opinion, it was as if an abyssal old demon broke the seal and walked towards him, and the terrifying power swept over, and he lowered his head even more, not daring to look directly.

Lin Fan frowned slightly, this aura is indeed a little powerful, but fortunately, it is not so terrifying.

The black shadow was getting bigger and bigger, but when it was about to reach the front, it was empty, and when Lin Fan looked down, he was stunned.

At most one meter tall, and it looks very old, could it be that this is the Great Demon Master?

"Well, that's good. The Great Demon Master raised his head and looked at Lin Fan, and nodded with satisfaction.

The man immediately said respectfully: "It's good that the Great Demon Master is satisfied." ”

"You come in with me. The Great Demon Master said, and then walked inside.

Lin Fan didn't think much about it, but followed behind, wanting to see what this great demon master was going to do.

Just as he was thinking about these things, the voice of the Great Demon Master came, "You will be my assistant in the future, you must be familiar with my work, the best and perfect fusion of humans and demon beasts, to form the strongest war weapon." ”

"But I'm not going to tell you anything about the job, you need to learn in research, and if it makes me feel like you can't help me, then you're the material for these fusing with monsters. ”

The Great Demon Master said coldly, and then pressed his palm against the button on the wall.

Suddenly, two holes opened in the wall above, and a human being chained was put down, while the other was a demon beast.

"Ahh The human roared and struggled, and the chains rattled, "You demons, you must not die well. ”

The Great Demon Master grabbed a token hanging from the feet of this human being, "Disciple of Yanhua Sect, Earth Gang Yizhong, captive." ”

"Well, it's a very good material, but you can experiment with the latest results, the perfect replacement of the demon beast heart and the human heart. ”

Lin Fan looked at this person, his brows furrowed slightly, but he didn't expect that it was really an experiment with a disciple of the Yanhua Sect, but as a fellow sect, how could he watch the same sect being studied.

This great demon master is really a nasty guy.

"Great Demon Master, the perfect exchange of hearts you said, didn't it work. Lin Fan said.

As soon as these words came out, the Great Demon Master's movements suddenly stopped, and then a violent and angry aura erupted, "What are you talking about? You actually said that I didn't succeed, and you, as an assistant, are you questioning me about the Great Demon Master?"

The aura that erupted from the Great Demon Master was indeed very strong, but in Lin Fan's opinion, it was useless.

"Why, as a great demon master, can't you afford to fail?, actually, I think your research method is wrong. Lin Fan said calmly.

The Great Demon Master, who was already on the verge of eruption, slowly withdrew his breath after hearing this, "Wrong? Why is it wrong?"

Okay, very good, since you ask why it's wrong, then I'm going to fool you today, after all, in my previous life, I was a salesman.

"Have you been experimenting with the people of Yanhua Sect?" Lin Fan said calmly, with his back to the Great Demon Master, he kept winking at the man on the chain, signaling to stop screaming, I was saving your life.

However, the man on the chain couldn't understand this eye transmission, but was still scolding angrily.

The Great Demon Master pondered, "Yes, what's wrong with that. ”

"Hmph, that's a big problem, I don't think you understand the true meaning of blood at all. Lin Fan said coldly, revealing a look of disdain.

"Are you laughing at me?" How could the Great Demon Master not hear Lin Fan's tone, and suddenly roared angrily, as if he could kill Lin Fan at any time.

However, in Lin Fan's opinion, this great demon master was really too irritable, but he didn't care, he could see that this great demon master might be a pervert who specializes in the fusion of humans and demon beasts.

"What, don't you want to know, why is this?" Lin Fan looked at the Great Demon Master and asked indifferently.

"Say, why, if you can satisfy me, I will reward you." ”

"Why don't you use the disciples of the Rizhao Sect to experiment?" Lin Fan said.

"Rizhao Sect disciples?" the Great Demon Master raised his head, "Why do you want to use the disciples of the Rizhao Sect to experiment, there are obviously these slaves of the Yanhua Sect, what do you want to use the Rizhao Sect for?"

Lin Fan shook his head, "You don't understand, this is a problem between blood, the mystery of blood, it is very complicated, the most common are A, B, AB, O four major blood." ”

"Wait, what are you talking about, what are the four major bloods?" When the Great Demon Master heard this, his head suddenly became bigger, he couldn't understand what the other party was saying, and he didn't understand the four major types at all, and he hadn't even heard of them.

Lin Fan smiled, "I haven't even figured out the four types of blood, so I came to study the fusion of humans and demon beasts, I'm afraid you're dreaming, or you're trying your luck." ”

"Tell me, what does this mean?" The Great Demon Master felt as if he had opened a new door, and inside this gate, there were many unknown things.

"This disciple of the Yanhua Sect is not suitable, change to the Rizhao Sect. As soon as Lin Fan's voice fell, he stopped talking, as if you didn't change, and there was nothing to talk about.

For the Great Demon Master, he was now eager to know what all this was all about, and then he walked around, suddenly thought of something, and suddenly pulled the switch, the Yanhua Sect disciple went up, and another Rizhao Sect disciple came down.

This disciple of the Rizhao Sect was punished here because he made a mistake and felt the fear here, but at this moment, when he saw the situation around him, he roared.

"What are you going to do, I'm a disciple of the Rizhao Sect, I'm just punished to stay here for a year, what are you going to do?" The disciple saw the situation around him and immediately understood that something was going to happen.

"Is he suitable?" the Great Demon Master stared at Lin Fan with a dead gaze.

Lin Fan nodded, "Suitable." ”

"I hope you don't lie to me, or you'll die a miserable death. The Great Demon Master did not hesitate and immediately took action, the disciple struggled, but he did not have any power to resist.

Poof!

The sound of skin scratching.

"No, Great Demon Master, you can't do this to me, I'm a disciple of the Rizhao Sect, you can't use me for research. ”

The Great Demon Master, who had entered the state of research, went completely crazy.

Lin Fan thought about it, he originally wanted to kill all the people here, but he suddenly found that this great demon master seemed to be somewhat useful.

Thinking about the horror of that huge war beast during that war period, it is enough to see how in-depth the Rizhao Sect's research in this area is.

Puppets of life and death.

This thing is a treasure, and if it is used to control this great demon master, it may be a good choice.

Just as Lin Fan was thinking about this, a mysterious power fluctuation came.

"Hahahaha!" the Great Demon Master smiled maniacally, "It's successful, it's really successful, the hearts of humans and demon beasts are perfectly integrated, and I really succeeded." ”

The body that was being used for research stood up suddenly, and the originally cloudy eyes suddenly burst out with blood-colored light, and at the heart of the disciple of the Rizhao Sect, cyan meridians appeared, coiling there like tree roots.

Roar!

A roar erupted from the disciple's mouth, and then under the order of the Great Demon Master, he stood aside obediently.

"How do you know this?" The Great Demon Master looked at Lin Fan, as if he didn't expect this assistant to know so much.
