In the castle, Grey sat on a chair, in front of him was a flame demon tied tightly with iron chains and handcuffs and shackles.

"Damn mortal, let me go, I'm going to kill you." The flame demon roared, with sparks flying in his mouth, but there was no fire in hell at all.

Of course, this is normal. No matter which demon is pulled out to study every day, he will be extracted from the body of hell fire and other mysterious powers by various methods. There are also various sealing props on his body, and he will still become like this, becoming a muscle demon who relies solely on his body.

The word "muscle demon" is only compared to mortals, because his physical strength has also been weakened.

It is not that the seal props are weakened, but that they do not eat or drink for several days, and do not give them a chance to recover their energy. Even the most powerful person will be weak.

Perhaps in a few months he will become the first devil to starve to death on earth.

Thinking of this, the flame demon felt a little desolate in his heart. If he had known that he would not have come to the world even if he had broken his hands and feet.

I thought it was a good job and could also have a large number of human souls to improve their strength, but I didn't expect that I would become an experimental guinea pig in the end.

As for anger, it was all pretending. He no longer had much strength to be angry. As a devil, how could he surrender to a human being?

"Don't call so loud that no one can hear it." Grey shook his ears and shrugged.

As an excellent magician, how could he leave such obvious loopholes for him? Before he was released, he had already set up a magic circle to isolate the sound. No matter how loud he was, no matter how loud he was, people outside could not hear it.

"I've been hungry for so many days and still have the strength to yell. It seems that I'm not at the limit yet. Let's continue to be hungry. I was going to give you a piece of food."

"Contribute some more blood, the last experiment has not yet come out." Gray muttered while preparing the things.

The demon also needs to eat. He doesn't know about the higher-level demon king, but the flame demon can't survive without eating or drinking.

In hell, powerful monsters also need to feed on weak monsters. Weak monsters do not even have wisdom and will only continue to reproduce and kill and swallow each other.

The Fire Demon's ears are naturally very sensitive, and Gray cannot lower his voice, so even after being hungry for so many days, he heard Gray's words.

After hearing this, his legs went weak and he fell to the ground, "Sir, I can be your servant. Please give me some meat. If you continue to take it like this, I will die."

"If I die, you want to get fresh demon flesh and blood again, it will be difficult. As long as you give me some food, I will not die. You can do whatever you want."

For demons, dignity is nothing but bullshit. Only oneself is the most important thing. Even if the object is a mortal who is looked down upon by him, he can choose to surrender.

Cruel and evil, cunning, selfish, this is the devil. What is better to die than surrender, loyalty and righteousness, that thing has nothing to do with them.

As long as they can survive and become stronger, they can do anything. This is the law of hell.

"I told you a long time ago that you can survive by cooperating well. Why didn't you do it before? A waste of everyone's time." Gray sighed.

He had told the Flame Demon before that, by cooperating well, you can get some of the things you want. Although human soul and flesh are not good, beef and mutton are still OK.

Unfortunately, this guy had to be stubborn at that time and was unwilling to cooperate if he was beaten to death. I don’t know how he figured it out now.

The flame demon cracked his bloody mouth, "I used to think you would kill me soon like those stupid demon hunters. Now I have discovered that you are definitely a strong man with a broad mind and unparalleled wisdom. I am willing to cooperate with you."

As he said, before, he felt that he would die, so he naturally didn't have to ask for forgiveness. Now he gradually realized that the other party really didn't have that idea, and he looked easy to talk to, and he would naturally not give up the opportunity to survive.

"You can sign a contract with me and make me your servant so that you don't have to worry about me running away or rebelling." The Flame Demon said sincerely, and the suggestions made were also very feasible.

"What contract?" Gray said curiously.

He can do things like contracts, what is the devil's contract? What magical abilities do he have.

"No one can break the contract with the souls of our two sides." The Fire Demon said honestly.

Gray continued to ask, and the Flame Demon said it carefully. It turned out that the so-called contract is to draw out part of the soul power of both parties, form a contract, and then return to their respective bodies, so that the contract can take effect.

After the introduction of the Fire Demon, he said that he was really hungry and hoped that Gray could sign a contract with him as soon as possible and then provide him with some food.

However, Gray just smiled at his suggestion. Although the Fire Demon doesn't look very smart, he is a devil at least. He signed a contract with the devil and only then did such an irrational thing if his brain was eaten by a zombie.

"You won't be tampering with the contract, right?" Although he was not planning to sign the contract, this did not prevent him from continuing to collect some information.

"No, absolutely no, the contract is absolutely fair and just. You are the master and I am the servant." The Flame Demon mistakenly thought he was moved and said quickly.

"After you become my master, you can let me do anything. I will be your best assistant, stronger than the demon hunter around you."

"Ly, Gray, he is lying, beat him." The elf flew over with a piece of barbecue, looking at the Fire Demon with his eyes "ferious" eyes.

Xiao Moli was really unexpectedly annoying to the Fire Demon, and she would instigate Gray to beat him up every time.

"No, I..."

The Flame Demon wanted to explain, and Gray waved his hand and interrupted him, "Okay, I didn't plan to sign a contract with you, and it's unnecessary to explain. As long as you cooperate with me well, you will have food to eat. It's that simple."

Xiao Moli's words further proved that the Flame Demon is worthy of being a devil who came out of hell. Although he is not very smart, he also has the cunning that the devil should have.

The Flame Demon didn't want to give up and continued to persuade him, wanting to let Grey sign a contract with him.

Gray found it a little funny. Doesn’t the Fire Demon know that being so anxious makes him feel even more ill-behaved?

He took out a piece of fresh raw meat, and Gray directly used magic to send it to the Fire Demon's mouth, "Stop talking, eat it quickly, cooperate well after eating."

The mouth was stuffed with raw meat, and the flame demon could not speak anymore. He kept chewing his mouth, and finally stopped persuading him and tried his best to deal with the meat that kept flying into his mouth.

But after just a few sips, the Flame Demon felt that there was no food and looked at Gray with grievance, "Sir, give me some more. I've been hungry for so many days, and you often draw things from me. This is not enough."

The flame demon was tall and could not satisfy him at all. However, Gray would not give him food anymore. He could only maintain his immortality. He was really strong. What if he broke free from the seal? He would have to try his best to catch it back.
