"Host, as long as krypton gold is 20 trillion, the great demon in the immortal cauldron can be directly refined."

The system gave an answer neatly, but this answer made Mu Fan very dissatisfied and even a little angry.

He suddenly reacted and cursed: "The crap-sucking goods, you said before that it would take 20 trillion yuan to refine the ancient beast Nine Infants. Now, it takes 20 trillion yuan to refine this more powerful ancient demon. Do you think I am a fool?"

"Nine Infants cannot be stronger than the ancient demon sealed here, right?"

Mu Fan questioned in his heart with some annoyance, feeling like he was fooled by the system.

"The host, it takes at least 20 trillion to refine an ancient-level existence. You can choose to refine the four ferocious beasts, or refine the ancient demon sealed in the immortal cauldron."

The system gave an explanation without any haste, but Mu Fan was so angry that he always felt that the system was deliberately trying to cheat him.

Buzz!

At this moment, the altar suddenly trembled, countless ancient runes jumped violently, and the whole house seemed to come alive.

Everyone was shocked.

"What's going on?"

On the altar, Xiao Wen and others looked at the shaking altar in horror, panicked one by one, not sure what had happened.

Around the altar, the four ancient ferocious beasts suddenly roared together, and strong lights emerged from their bodies, intertwined each other and poured into the altar.

Boom!

In an instant, the entire altar came alive, and countless ancient patterns and traces flickered and intertwined, constantly emerging, forming an ancient seal.

"It's the seal!"

Ye Tian had a wide range of knowledge and immediately understood something.

Xiao Wen, who was beside him, had a pale face, thought of something, and exclaimed: "No, this is the great demon attacking the seal and trying to break it out."

"The four ferocious beasts work together to seal it, we happen to be on the altar, so we are in trouble now."

Xiao Wen remembered something, her face turned pale and became extremely regretful.

"It's over, we were treated as sacrifices, blood sacrifices to the immortal cauldron, thus smelting the ancient great demon."

When she thought of this, she looked panicked. She no longer had the calmness and confidence she had before, but she was just a panic.

Now, I'm in trouble.

The altar was originally intended to seal the immortal cauldron and used to sacrifice the immortal cauldron, and the sacrifices were of course various living things and creatures.

No matter what kind of living thing it is, as long as it is placed on the altar, it will be sacrificed to the immortal cauldron, and then form a powerful amplitude to refine the great demons in the immortal cauldron.

There is an ancient immortal who wants to use this method to refine the great demon. It is not clear who arranged the four evil seals.

Buzzing...

The altar shook, the immortal cauldron kept trembling, the iron chains on it kept trembling, and bursts of clanging sounds came, and fairy light lingered.

For a moment, everyone was panicked.

"The big demon is coming out?"

Ye Hongchen looked at the Immortal Cauldron with horror on his face. The few of them were in an extremely dangerous situation and could no longer do it if they wanted to leave the altar.

After the entire altar was activated, a halo formed, which tightly imprisoned the few of them on the altar, and could only wait for the beginning of the sacrifice.

boom!

A roar came, everyone's heart was all over, and their blood seemed to break out of their bodies, scaring their faces to the ground.

"Immortal Cauldron!"

Xiao Wen exclaimed, everyone looked at the Immortal Cauldron, and the sound came from inside. The terrifying demon was actually rushing to the seal of the Immortal Cauldron.

The entire fairy cauldron emitted a hazy fairy light, constantly flickering, and the cauldron body trembled, expanding and shaking again and again, as if it could not withstand the impact of the things inside.

As the immortal cauldron was about to escape from the seal of the altar, a sudden roar came from all around, and the four ferocious beasts roared together.

"roar!"

The four ancient beasts roared together, and their bodies suddenly dispersed, turning into four powerful original powers and injected into the altar.

The four evil seals kept flashing, and iron chains coiled around the immortal cauldron, blocking it layer by layer to prevent it from breaking free.

At this time, the altar began to absorb the strength and origin of several people, and flowed into the altar bit by bit.

"The sacrifice has been started, and we can't escape."

Xiao Wen looked around in despair, and the few people were also locked firmly by the altar, and even the legendary Ye Tian couldn't break free.

They were about to be swallowed directly by the altar.

"town!"

At the critical moment, a cold shout came from the top of the head. Before everyone could react, they saw that the power that originally bound them suddenly became lighter and their bodies relaxed.

Everyone didn't care about it, so they took this opportunity to jump down, flew down from the altar, and left the altar.

As soon as they escaped from danger, everyone had the opportunity to look up at the altar, and there was a young figure appearing at some point.

"Mu Fan?"

"Brother Mu?"

A few screams came, Ye Hongchen, Xiao Wen and the fat man widened their eyes, and they looked at the person who suddenly appeared, which turned out to be Mu Fan.

At this moment, the two of them were quite shocked inside. Unexpectedly, the one who saved them just now was Mu Fan.

"Why is he here?" Xiao Wen was confused and stared at Mu Fan on the altar.

He was pressing on the altar with one hand, and his powerful power and cultivation were exploding, suppressing the power of the altar.

"He is Mu Fan?"

Ye Tian's eyes were shining, and he looked at Mu Fan secretly, and the more he looked, the more frightened he became.

I didn't think it was amazing now. This man is simply a bottomless pit and I can't see his background at all.

"What did you do?"

While suppressing the altar, Mu Fan glanced at the people here, with a hint of helplessness on his face.

Xiao Wen lowered her head awkwardly, feeling guilty, feeling that she had been found strange as a thief.

"Brother Mu, you came too timely. If you are a little later, we will not even have any scum left."

The fat man screamed with excitement, looking particularly excited.

Ye Hongchen looked at Mu Fan calmly, with a hint of inquiry in his eyes, why did this guy suddenly appear?

She remembered Qiongqi who had suddenly appeared before, and suddenly realized her heart and understood.

Perhaps, Qiongqi was activated after Mu Fan came in.

"Brother Mu Fan, be careful, this is an ancient seal, there is a big demon seal inside, you can't let it come out, otherwise no one can stop it."

“The Kingdom of God is useless.”

Xiao Wen said something solemnly.

Mu Fan thoughtfully after hearing this. Perhaps, what Xiao Wen knew, what he must have experienced in his previous life to be so sure.

But it is not difficult for him to suffer. Since it is so dangerous, it is better to destroy it directly. Although it is a little expensive, you can get a fairy cauldron.

There is also an ancient demon of unknown level. Mu Fan is still looking forward to what kind of harvest he can achieve after refining it.

20 trillion yuan, refining an ancient great demon of unknown level will obviously make a profit. Regardless of whether it is profitable or not, the first priority is to destroy the great demon before leaving.

Otherwise, Mu Fan would probably not be able to withstand the great demon once he came out.

"System, what can I get after this great demon is refined?"

Although he decided, Mu Fan still asked the system a little worriedly what he could get.

After all, 20 trillion is not easy to make.

"Host, as long as the refinement is successful, you can obtain all the origins of the ancient great demon, including its ancient memory information."

The system was very straightforward and gave an answer that Mu Fan could not refuse.

The ancient great demon is, and it is unclear at what level it is. If you want to know, you will spend money to let the system scan it first.

But Mu Fan felt that it was a waste. Since he decided to kill it, there was no need to scan it again, which was simply unnecessary.

Buzz!

As if I sensed some kind of crisis, the immortal cauldron suddenly vibrated violently and struggled with a crackling sound. The immortal chain above actually came with a rattle, which was about to break at any time.

Seeing this, Mu Fan knew that he couldn't wait anymore.

"System, krypton gold, refine this ancient demon."

Mu Fan gritted his teeth and ordered in his heart to krypton gold to refine the ancient demon.

bite!

"Krypton gold is 20 trillion, and it starts to be refined."
