After the demon king said that, he directly attacked Mukai. In his opinion, Mukai was just a son who betrayed himself. He killed all his favorite women. Since he was not obedient, he destroyed it.

Mukai knew he couldn't beat him, but he chose to fight him head-on. He was the son of the king of the demon world, not a coward. This man has his father's face, but the strange feeling makes him feel that this man is just a man wearing his father's mask.

The demon king saw that Mukai was going to confront him head-on. He was really a guy who exceeded his ability. He liked his eyes very much.

"You know you can't beat me, why do you have to fight me head-on? I'll clean up you today." the demon king's expression was very angry. In his eyes, he didn't allow anyone to betray himself. Only those who betrayed themselves could be killed.

Mukai looked at the demon king and heard him say these words. His heart was cold. If he was really his father, he would never say such words.

"Even if I can't beat you, I'll fight for my life. You're so bloodthirsty, you're not my father at all."

Mukai said that he put his blood into Lingfeng's blood array and planned to complete the blood contract with Lingfeng.

Ling Feng must be very serious now before he can complete this array. When Mukai's blood is fully integrated with his own array, the blood deed is really completed. He can't break it halfway, otherwise he will hurt not only himself, but also the array will be destroyed.

Ling Feng opened his eyes, looked at Mukai and said, "Mukai, hold it for 15 minutes and the blood contract can be completed."

Mukai heard Ling Feng's words. His eyes were full of fighting spirit. It only took 15 minutes so that he could become stronger.

Mukai looked at Ling Feng and said, "I know. I will hold these fifteen minutes and let you complete the blood deed."

After Mukai finished, he looked at the demon king and began to fight with him.

The demon king heard Lingfeng say fifteen minutes. He looked at Mukai. Mukai was taught by himself when he was a child. It is impossible for him to win his life.

"Mukai, don't be whimsical. You'll be knocked down by me in less than three minutes. You can't wait to complete the blood deed."

Mukai looked at the arrogance of the demon king. He knew that he knew everything about himself, and he didn't know anything about his bloodthirsty father.

Ling Feng is fusing the blood of himself and Mukai. He is also worried that Mukai will not last for 15 minutes, so he sets up a border around him. Even if Mukai is injured, his barrier can resist for a period of time.

Mukai gathered his strength. He couldn't do such a thing unless he had to.

It takes a lot of energy to gather all his strength together. If he doesn't succeed, he may encounter danger.

The demon king watched Mukai untie the acupoints on his body. He didn't expect that he would work so hard to rush away all his strength and concentrate together. This can make his strength stronger, but for the demon king, he eats more salt than he eats rice. Such a way is to find a dead end.

"Mukai, you look like this. Don't you really worry that your body can't bear such strong pressure and finally let yourself go crazy?"

"Go crazy, I will defeat you too." Mukai said, and he attacked the demon king.

The demon king watched him attack quickly, and he escaped quickly when he attacked.

The demon king didn't expect Mukai to concentrate all his strength so badly, but if he used too much power, it would damage his meridians. The villain would work so hard. He really underestimated him.

"Inverse son, I didn't expect you to be able to do this. I won't let you live today."

The demon king attacked Mukai with lightning speed.

If at ordinary times, Mukai could not escape such a fierce attack. Now his abilities in all aspects are constantly improving.

Such an attack for him, his attack, he can still barely hide, as long as wait 15 minutes, through these 15 minutes, he can rely on Ling Feng's power to make himself stronger.

Ling Feng is still merging, and he can't be distracted to manage the affairs between Mukai and the demon king. If he takes back the blood array, it will hurt himself and Mukai, otherwise the blood contract won't have such a strong cooperation.

Mukai played chess with the demon king for several rounds. Finally, he was beaten down. The disparity of strength made Mukai hate himself. I didn't make it for fifteen minutes.

The demon king looked at Mukai who was beaten by himself and said coldly, "I taught you everything you learned. You want to beat me with what I taught you. It's just a fool's dream."

The demon king saw that the blood contract array was about to be completed. Now Mukai was knocked down by himself. He must destroy the blood contract array.

Just as he was about to destroy the blood contract array, he was bounced back by a white light. Ling Feng really has two sons.

The demon king also wants to continue to destroy Lingfeng's blood contract array, but Lingfeng hasn't even touched a hair. Continue. Once the blood contract array is completed, Mukai's strength will really improve.

After several attacks, Ling Feng's border began to weaken.

Finally, the sound of "Bang..." was heard, and Lingfeng's border was also destroyed.

The demon king mercilessly attacked Ling Feng.

If Ling Feng gets hurt at this time, the blood contract array will bite back.

Mukai looked at the demon king. When he was about to meet Lingfeng, he suddenly jumped out and stood in front of Lingfeng. Such a blow did not hurt Lingfeng, but Mukai.

"Poof..." Mukai couldn't bear the slap. He spit blood directly and sprayed it into the blood deed array.

The bright red blood fused with Ling Feng's blood contract array.

The demon king looked at such a blood contract array. He didn't think that Ling Feng's ability was really strong, otherwise he couldn't emit such dazzling light. It's just a pity that the blood contract array has not been completed, otherwise it will pose a certain threat to him. God really helps him.

The demon king was about to attack Ling Feng, but finally Mukai resisted tenaciously and hindered the demon king.

When the demon king finished dinner, he hid from Xiao Linlin and began to regulate his breathing. When he saw the red light, he was curious about what happened there. He and Huolong went to see it.

Unexpectedly, as soon as they arrived at their destination, they saw Mukai and the demon king fighting.

The demon king's body hasn't fully recovered. He looked at the fire dragon and said, "fire dragon, your ability should be able to beat the demon king. Go up and help Ling Feng. The blood contract array is opened and can't be interrupted. It's a thank-you gift for saving my Lord."

The fire dragon heard his master's orders. When the demon king was ready to attack Ling Feng, he blocked the demon king's attack.

The demon king looked at Cheng Yaojin who was killed halfway. He said angrily, "who are you? Don't stop the king from doing things."

The fire dragon looked at the demon king and his eyes showed cold light. This man also deserves to know his identity. He is a guy who exceeds his ability.

"If you want to know who I am, you will know if you can beat me." Huolong said, and a red fireball appeared on his palm. He was born an expert in playing with fire, so he can easily control fire.

The demon king looked at the fire in the fire dragon's hand. He was not afraid, but when the fire dragon approached him, he felt a burning feeling. Ordinary fire can't hurt yourself at all. I didn't expect it to be so hot.

The fire dragon and the demon king have seen the attack speed of the demon king in the air just now. I have to say that the attack speed of the demon king is very fast. It was also quick, accurate and ruthless, without a trace of hesitation. You can't hesitate to fight, or you'll hurt yourself.

The fire dragon punched the demon king.

The demon king was hurt by the fist of the fire dragon.

"Bang..." the demon king's body hit a tree directly. The tree was under great pressure and was finally pushed down by roots.

Mukai will be surprised when he looks at the fire dragon's moves, because it's too fast and powerful.

Seeing that the situation was bad for him, the demon king left the green mountain without worrying about firewood. He ran away directly. As the king of the world, he was so embarrassed. He vowed to get back today's shame.

The fire dragon helped Mukai up and asked coldly, "are you okay?"

Mukai covered his chest, shook his head and said, "I have nothing to do. Thanks to your timely appearance, otherwise I don't know how to deal with him."

The fire dragon looked at the demon king in the sky and said, "master, you can come down."

The demon king landed. He looked at the blood deed array that was about to be completed and looked at Mukai. He felt that Mukai's fighting spirit made him admire it.

Mukai saw that the man who came was the demon king. He thanked him and said, "thank you for your help."

The demon king said faintly, "I owe Ling Feng a life. I saved you just for Ling Feng. You should finish the blood contract array with Ling Feng quickly. If someone bothers me, I will clean up everything for you."

"Trouble," Mukai said, and he entered Lingfeng's blood contract array.

Ling Feng looked at Mukai and chanted a curse while fusing his blood with Mukai's blood.

Mukai was wounded by the demon king. Once the blood contract array was completed, his wounds gradually recovered.

Mukai feels like he has been reborn. The whole person's physical strength is full of power. Is this the power of blood contract?

Originally, the red light slowly disappeared, so the contract between the two people was really established.

Ling Feng opened his eyes, looked at Mukai and said, "Mukai, the contract is completed."

Ling Feng knew that the devil was coming. He looked at the devil and asked, "devil, why are you here?"

When the demon king heard Ling Feng ask why he was here, he just replied coldly, "I can't sleep, so I want to adjust my breath. I saw you fighting with the demon king by chance, so I helped."

Seeing that the contract was completed, the demon king looked at the fire dragon around him and said, "fire dragon, it's late. I'm so tired. Let's go back first."

Ling Feng watched the devil and little fire dragon leave. For a moment, he felt that the devil was not as cruel as the legend. He was also very human.
