"Okay, I promise you, if you win, then I'll tell you everything about the altar, including how to use it, but I don't know if I can use it or not, because it hasn't been opened for a long time," the Demon Emperor said.

"Okay," Ye Feng agreed.

The Demon Emperor wanted to give Ye Feng some soldiers and horses, but Ye Feng shook his head and refused.

"I'll be enough for myself," Ye Feng disappeared after speaking.

Leaving the Demon Emperor with a look of surprise.

"Hmph, at a young age, he said wildly, I don't know how the emperor knew such a person, and he actually wanted to defeat the alliance of the eight kings alone, which is impossible for us to do," an old man of the demon clan stood up and said.

"Although I don't know either, I believe he can," the Demon Emperor said, after all, he is a disciple of the Demon God, and there must be something to save his life.

Ye Feng came directly to the gate of the imperial city, standing quietly in the air, waiting quietly, and less than a day passed.

"Haha, the Demon Emperor is here!"

An arrogant voice came, and then I saw that in the distance in the air, densely packed with demons, like locusts, flew over, led by eight people, and everyone's cultivation was in the middle of the Mahayana period, and there was also a late Mahayana period.

When Ye Feng saw that someone was coming, he didn't say a word, and directly covered the demon clan with a big palm that covered the sky and the sun.

"It's not good, there are masters," the Eight Demon Kings struggled to resist.

"Poof!"

With one move, Ye Feng injured the eight demon kings, and as for those subordinates, there were countless casualties.

Some of the Demon Emperors were watching this battle in the palace, and when they saw that Ye Feng had severely injured the Eight Great Kings with just one move, they all secretly wiped their sweat in their hearts, what kind of strength is this.

"Who are you?" a demon king looked at Ye Feng standing in the air in shock.

"Father, he is Mu Xiyan's man, and my father must help me avenge my revenge," Ma Ning said beside him.

"What!

King Manan slapped Ma Ning directly in the face.

"You waste, you know that the Demon Emperor found such a master, not to mention, and even let me attack, how did I give birth to such a son as you," King Manan said angrily.

"I don't know his strength, how could I have thought it would be so strong," Ma Ning said aggrievedly.

King Manan looked at Ma Ning and really wanted to slap him to death.

"Okay, King Manan, now that the arrow is on the Xuan, we have to send it, so we have to deal with him with the things that are used against the Demon Emperor," said a demon king.

"It's only like this, it's just that the hole cards are revealed so quickly, I'm a little unwilling, and I don't know where the Demon Emperor found such a master, and the strength is estimated to be not inferior to the Demon Emperor," Manan Wang said.

"Okay, let's summon!"

King Manan threw a scroll into the air, and the eight demon kings entered the scroll together.

"This is the Seal Scroll! What are they going to summon?" said an old man of the Demon Clan.

"Could it be!" the Demon Emperor didn't know what he was thinking, and his face was solemn.

The sky darkened, as if some demon had awakened.

Ye Feng held his hands behind his back in the air, quietly watching all this.

"Who summoned me, are you ready for blood?" a terrifying voice came from the scroll.

"You're crazy, you want to summon him awake, do you know that this will bring ruin to our Demon Realm," the Demon Emperor said at this time.

"Demon Emperor, you have finally come out, don't continue to be a shrinking turtle, are you scared, haha," King Ningnan laughed.

"Aren't you afraid that he will kill you too?" said the Demon Emperor.

"What can you think of, can we not think of? What do you see it is?" said King Manan with a collar in his hand.

"Demon Collar! You actually found the Demon Collar, it seems that you have wasted a lot of effort to deal with me," the Demon Emperor said in shock.

Demon collar, as long as you wear it, no matter what kind of cultivation you do, it will be controlled by the refiner, and even the soul will be controlled, and it can only be slaughtered by others, so King Manan is so confident and not afraid of the evil god against the water.

"You are ready to die," said King Manin arrogantly.

"Is the thing in this scroll very powerful?" Ye Feng said as he looked at the Demon Emperor.

"Of course it's amazing, there were once two gods in the demon world, one was the demon god, that is, your master, and the other was the evil god, the evil god and your master fought for the supremacy of the demon world, and the two of them fought in the sky, and finally your master won and sealed the evil god in this scroll," the demon emperor said.

"I see, then the strength of this evil god seems to be very strong, and it is estimated that he has surpassed the peak of the Mahayana period, and I am really looking forward to fighting him," Ye Feng said.

The Demon Emperor looked puzzled, you are just a disciple of the Demon God, this evil god is an equal existence to your master, it seems that this Ye Feng is a little too high-eyed, even the Demon God does not dare to say such a thing when he sees the evil god.

"Evil God, put this collar on the head, and I can let you out," King Manan said to the being inside the scroll.

"Okay, just let me out, and I'll promise you anything," said the evil god.

"Okay, you go on," King Manan tossed the collar into the scroll.

King Manan sensed that the evil god had put on a collar, and his face was fiercely happy.

"Prepare the blood!"

Manan Wang said.

Then dozens of masters of the Tribulation Period held a large basin together, which was full of fresh blood, and the large basin that could be lifted by dozens of masters of the Tribulation Period could be imagined, and the blood in it was full.

Ye Feng looked at the blood in the big basin, how many people do you have to kill, at least it is estimated that it will cost trillions of lives, and they have just been killed, no matter how indifferent Ye Feng is, his heart trembles slightly, this is really a group of people who kill people without blinking.

"Worship the evil gods!"

There was a terrifying suction inside the scroll, and the blood was sucked into the scroll like a waterfall.

Then the Eight Demon Kings watched all this excitedly.

"Quack, I'm finally out, the demon god doesn't know about you"

"It's not good, the evil god is coming out, Ye Feng, you quickly inform your master, now only your master can beat him," the Demon Emperor said anxiously.

"Just leave it to me," Ye Feng said, he could only say this, after all, he was a fake Demon God apprentice, where to inform the Demon God, he didn't even know what the Demon God looked like.

"Are you okay?" the Demon Emperor asked, after all, this is an evil god.

"Don't worry," Ye Feng said calmly.

"Whew!"

A pure evil aura rushed towards the sky, and the black clouds in the sky changed for a while.

Suddenly, a big hand came out of the black cloud and crushed the scroll at once.

"Finally free!" the evil god's voice came from the air.

"Evil God, come over to me, hurry up and kill the Demon Emperor, or I'll activate the Demon Collar," King Manan said.
