Seeing that Dugu Hong had nothing to do with himself, this guy was speechless. There was an inexplicable panic in his mind. He didn't know what Dugu Hong would do next. At this time, he can only take a better attitude.

"I..." then, a small mass of black magic Qi flew out of his body. This evil Qi is quite different from the evil Qi that Dugu Hong had seen before.

The evil Qi that Dugu Hong had seen before was like a cloud in the sky. Floating everywhere. But this evil spirit seems to have a spirit in general, and it will last forever. This made Dugu Hong curious. After all, a thing that has never been seen before, for the first time, naturally has a certain degree of curiosity.

"Please plant the mark of your soul on it." This guy is very straightforward. He asked Dugu Hong directly.

Only then did Dugu Hong realize that it was like this. He had just signed a master servant agreement with the vultures. Of course, it didn't seem so complicated at that time. He just bites his index finger and presses it on the Griffin's head, and the contract is formed.

However, today we are facing the demons. But he is a member of the human race after all. This kind of experience has never been before. However, Dugu Hongdao, who had a lot of experience in his previous life, was not embarrassed by this.

"Do you really want to follow me?" I'm not very willing to say that. It is not easy for him to let this guy know that he wants to be his own servant.

"Of course, I must be loyal to my master." Although there are ten thousand people in his heart who are unwilling, the situation is not as good as others at this time. It's best to pretend to be a grandson.

"Then tell me what I should do?" At this time, Dugu Hong would not easily sign a contract with him. In case of any accident, all his previous efforts are in vain. He doesn't want to make wedding clothes for others.

"You just need a drop of blood on that one." The guy said with a look of shame and indignation. To tell you the truth, as a demon among the demons, he also has his own pride. But today he has to sell his dignity in order to survive. This kind of feeling makes him very uncomfortable.

But this feeling can't be mentioned to others. The opposite Dugu Hong didn't care about his face. It made him want to cry without tears.

"Is it?" Dugu Hong looked at him like I didn't believe him at all and said. To tell you the truth, that's exactly what he thought at this time. It's hard to get through. Naturally, I want to live forever! If you are captured by yourself in this place. At that time, even in that world, he can't forgive himself.

"Of course. You can rest assured. " I'm sure I won't cheat you. The more he was like this, the more worried Dugu Hong was. After all, he has always been very cautious. I've never done anything risky. Although Xia Liu didn't care about anything in front of them, he was still afraid of losing everything. Of course, I don't want to be cheated by others.

Now if someone is in front of him, he will not be so helpless. Because, after all, someone can give him advice. What's more, they know the world very well. And he, up to now, has never done such a thing. Naturally, the society will not understand it.

"If you don't believe it, I'll explain it to you." This guy finally knows that Dugu Hong is a rookie in this aspect. However, he didn't really want to cheat Dugu Hong. Because his life was in the palm of his hand. Even if he got it, Dugu Hong might kill himself in a short time.

Next, he talked about the situation in the world about how people signed the contract in July 2001.

There are two situations in which people in this world sign contracts with each other. One is equal contract, the other is master servant contract. Equal contract is based on equality and mutual benefit. As long as one party dies, the other party will die in an instant no matter where it is. And the signing of this kind of contract is very complicated. First of all, both sides must drink each other's bowl of blood, so that you have me and I have you. Then the two sides print their own blood stains on each other's forehead. The contract is completed only after it has been approved by God.

And the master servant contract is much simpler. As the master, he only needs to bite his finger and let the blood melt into the servant's soul. After the recognition of heaven and earth, it is really completed.

"I see. In that case, let's try. " When Dugu Hong heard his explanation, it was very reasonable. Naturally, he had no objection.

After biting his index finger, he printed it directly on the gathering magic. Then he felt the blood flow on his fingers speed up a lot. Just for a moment, a few drops of blood on the finger melted into the soul mark.

At the same time, he also smoothly felt that there seemed to be a special connection in his sea of knowledge. This sense of continuous writing makes him feel as if he can feel the thoughts in other people's hearts.

Of course, at this time, he has been able to clearly perceive many changes in the sea of knowledge of the demon king. With the emergence of one of his thoughts, the devil on the opposite side showed a look of pain“ Master, it can't be like this. If I do that again, I will be finished The guy begged for mercy. Hearing this, Dugu Hong knew that the master servant agreement between them had been signed. He can now clearly perceive the whole process of this guy's growth from a mass of evil Qi to the present. If he wants to do something, it's just an idea. This guy may be... "OK. In that case, I'll take you. However, I still advise you to be obedient. Otherwise, even if you are far away, I will not let you go. " Dugu Hong said coldly“ This is natural. Master, please rest assured. I will do my part. " The devil said quickly and flatteringly“ It's best to be obedient. Otherwise, hum Dugu Hong said coldly. Now he has a good understanding of the demons. Next, he will have a greater grasp of the fight with the demons.
