In the castle, gray sat on a chair, in front of a burning devil bound with iron ropes and shackles.

"Damn mortal, let me go. I'll kill you." The Yan devil roared with sparks in his mouth, but there was no fire of hell at all.

Of course, this is also normal. No matter which demon is pulled out to study every day, it will also be extracted by various methods from the hell fire and other mysterious forces. The props with various sealing forces will also become like him and become a muscle demon relying solely on the body.

The word "muscle devil" is only relative to ordinary people, because his physical strength has also been weakened.

It's not that the seal props are weakened, but that they don't eat or drink for several days and don't give them a chance to restore energy. No matter how powerful they are, they should be empty.

Maybe in a few months, he will become the first devil to starve to death in the world.

Thinking of this, Yan devil felt a little desolate. He knew that he would not come to the world even if he broke his hands and feet.

I thought it was a good job and a large number of human souls could improve their strength. I didn't expect to become an experimental mouse in the end.

As for anger, it's all pretended. He doesn't have much strength to be angry now. Just as a devil, how can he be soft to a human?

"Don't shout so loud. Others can't hear you." Gray pulled out his ears and shrugged.

As an excellent magician, how could he leave such an obvious loophole for him? Every time before he was released, a magic array was set up to isolate the sound. No matter how loud he was, people outside couldn't hear him.

"I've been hungry for so many days and still have the strength to roar. It seems that I haven't reached the limit. Keep hungry. I was going to give you a piece of food."

"Donate some more blood. The last experiment hasn't yielded results." Gray muttered as he prepared his things.

The devil also wants to eat. He doesn't know about the higher-level devil, but the Yan devil can't live without eating or drinking.

In hell, powerful demons also need to eat weak demons. Weak demons don't even have wisdom. They will only continue to multiply, kill and devour each other.

Yan devil's ears are naturally very sensitive, and gray can't keep his voice down, so even if he was hungry for so many days, he heard Gray's words.

After hearing this, he directly softened his legs and knelt down on the ground, "Sir, I can be your servant. Please give me some meat. If you draw it again, I will die."

"If I die, it will be difficult for you to get fresh demon flesh and blood. As long as you give me some food, I won't die. Sir, you can do whatever you want."

For the devil, dignity is bullshit. Only himself is the most important. Even if the object is a mortal despised by himself, he can choose to give in.

Cruel, evil, treacherous, cunning, selfish, this is the devil. What would rather die than surrender, loyalty and righteousness are unparalleled. It has nothing to do with them.

As long as they can live, as long as they can become strong, they can do anything. This is the law of hell.

"I told you long ago that if you cooperate well, you can live. Why didn't you do it before? Waste everyone's time. " Gray sighed.

Before, he said to Yan devil that if you cooperate well, you can get something you want. Although human soul and flesh are not good, beef and mutton are still OK.

Unfortunately, this guy was so stubborn that he didn't want to cooperate. I don't know how he figured it out now.

The Yan devil opened his mouth, "I thought you, like those stupid demon hunters, would kill me soon. Now I found that you are definitely a strong man with a broad mind and unparalleled wisdom. I am willing to cooperate with you."

As he said, he didn't need to beg for mercy because he thought he was going to die. Now he slowly found that the other party really didn't have that idea and spoke well. If he could live, he would not give up the chance to live.

"You can sign a contract with me to make me your servant, so that you don't have to worry about my escape or rebellion." Yan Mo said sincerely, and the proposal is also very feasible.

"What contract?" Gray said curiously.

He can do things like contract. What's the devil's contract like? What magical abilities do you have.

"No one can break the contract signed with the souls of both of us." Yan devil said honestly.

Gray continued to ask. Yan devil said it carefully. The original so-called contract is that the soul power of both sides leads out a part to form a contract, and then returns to their respective bodies. In this way, the contract can take effect.

After the introduction, Yan devil said he was really hungry. I hope gray can sign a contract with him quickly and provide him with some food.

However, gray just smiled at his proposal. Although the Yan devil didn't look very smart, it was still the devil. He signed a contract with the devil and his brain was eaten by the zombie.

"You won't do anything in the contract, will you?" Although he did not intend to sign a contract, this did not prevent him from continuing to collect some information.

"No, absolutely not. The contract is absolutely fair and just. You are the master and I am the servant." Yan devil mistakenly thought he was excited and hurriedly said.

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

"Lie, gray, he's lying. Hit him." The elf flew over with a piece of roast meat and looked at the Yan devil with fierce eyes.

Little Molly is really an unexpected nuisance to Yan devil. She encourages gray to beat him every time.

"No, i

Yan devil wanted to explain, gray waved and interrupted him, "OK, I didn't intend to sign a contract with you. It's unnecessary to explain. As long as you cooperate with me, you will have food to eat. It's that simple."

Little Molly's words prove that Yan devil is also the devil who came out of hell. Although he is not very smart, he also has the cunning that the devil should have.

Yan devil didn't want to give up. He kept on persuading and wanted gray to sign a contract with him.

Gray felt a little funny. Didn't Yanmo know that he was so eager, but it seemed that he had a bad heart?

Take out a piece of fresh raw meat, gray directly sent it to Yan devil's mouth with magic, "stop talking, eat quickly, and cooperate well after eating."

His mouth was full of raw meat. Yan devil couldn't speak. He kept chewing in his mouth. Finally, he stopped persuading and tried his best to deal with the meat that kept flying into his mouth.

But after only a few mouthfuls, Yan devil felt that there was no food, and looked at gray wrongly, "Sir, give me some more. I've been hungry for so many days, and you often take things from me. This is not enough."

Yan devil is tall and can't satisfy him with anything, but gray won't give him any more food. Just keep him alive. He's really strong. What if he breaks away from the seal? We have to work hard to get it back.

After he swallowed the last thing, gray continued his experiment.
