"Boom!"

Before Mu Zifeng could react, suddenly, the earth shook.

The tremor was very strong, like a magnitude 10 earthquake in the world.

The mountains shook for a while, as if something was going to break the seal and break the ground, many buildings in the Demon Emperor City collapsed, and the sound of crying father and mother was endless.

The trapped array arranged by Mu Zifeng also flickered twice, and shattered. No one noticed that a demon soul was like black lightning, which suddenly drilled into the sky, and soon disappeared into the vast spatial turbulence.

If Mu Zifeng paid attention, he would find that the owner of the demon soul was the city lord of the Demon Emperor City. His physical body had been destroyed by Mu Zifeng's sword net, leaving only a wisp of remnant soul floating out. And all his subordinates did not escape the fate of being killed.

"What happened?"

Caught off guard, Mu Zifeng was also stunned, but he immediately found that a large ball of flames appeared in the sky for no reason.

The flame was extremely gorgeous, as if it had come from ancient times, and shimmered beautifully.

He knows that the more beautiful something is, the more dangerous it is.

Sure enough, as soon as the flame fell on the monks, they began to burn, and in the blink of an eye, the monks turned into blood and rose to the sky.

At this moment, the earth was still trembling, and the great ball of flames turned into raindrops, falling all over the sky and covering the earth.

"No! Could it be that someone wants to use heaven and earth to make alchemy? And the main material for alchemy is the monks in this city?"

Mu Zifeng was suddenly startled, he himself was shocked by his own thoughts.

As early as when he was at the headquarters of the Holy Sect, he read an ancient book, which recorded that the main organization had used the entire city to refine the pill, and the pill that was refined was called the Blood Pill.

The cultivation required to refine this elixir was extremely strong, and without the cultivation of the Eighth Order Great Demon Emperor or above, it was impossible to succeed at all.

And it must be four eighth-order Great Demon Emperor and above cultivators who have cultivated at the same time, otherwise they can't do it at all.

He immediately understood, why did the blade crush the jade slip, and leave everyone to die, he was probably already in collusion with the people of the lord's organization, what he had to do was to control the entire Demon Emperor City and facilitate the lord's organization to refine the blood pill.

Now that he saw that the general trend had gone, he had no choice but to let the people of the Lord organize intervene in advance.

This also explains why he did it early, it is likely that the main organization is going to make a big move and is impatient.

In that ancient book, the fact that the Lord organized the refining of the blood pill was only recorded, and as for how to crack it, there was no mention of it.

That's a shame!

Mu Zifeng couldn't help but feel a thick egg pain.

He originally thought that he had killed millions of people from the Lord Organization in the North Underworld, which had severely damaged the foundation of the Lord Organization, but now that he thought about it, it was a bit naïve, the Lord Organization had 20 million people, and the few people he killed or adapted were just a drop in the bucket.

Not to mention anything else, if the record in that ancient book is good, at this moment, the Lord Organization has at least four Great Demon Emperors of the Eighth Order and above here.

There are very few demon emperors, and the eighth-order great demon emperor is even more rare, which Cheng thinks that this main organization not only has it, but also four of them, how can this zhang fight.

But he is not a person who gives up easily. According to his cultivation, if he wants to get out of the Dan furnace formed by this heaven and earth, it can be said that it is as easy as a hand, even if he brings Feng Feifei and other people, after all, he still has a spirit bag.

But to put everyone on and take them out would be a bit whimsical.

Besides, he is gone, the billions of monks in this Demon Emperor City, how many blood pills have to be refined, how many demon emperors have already been.

If he is gone, can the Heavenly Dao Sect go?

If the Lord is allowed to organize the refining of the Blood Pill and create even a hundred Demon Emperors, will the Demon Netherworld Continent be able to stop their pace? What about the Xuan Demon Continent, let alone the Mangchuan Continent!

It's chilling to think about.

The only way now is to sabotage the plan of the Lord Organization, so that their plan is stillborn, if they can take the opportunity to kill one or two eighth-order Great Demon Emperors, it will be even more perfect.

After all, it would take countless years to cultivate an eighth-order Great Demon Emperor to succeed, if it was like a cabbage radish, wouldn't the streets be full of Demon Emperors?

The reason why the Blade was so busy rebelling was probably because the main organization had just cultivated an eighth-order Great Demon Emperor, at least it meant that they had just cultivated four eighth-order Great Demon Emperors, otherwise, why would they have gone earlier, wouldn't they have started refining the Blood Pill earlier?

Just do it.

Mu Zifeng's face also flashed with a hint of ruthlessness.

He waved his hand to set up a defensive formation, and injected all the spirit stones in the storage bag into the formation.

Although this made him feel very painful, but extraordinary means had to be used in extraordinary times, and now he had no way to retreat, so he could only make a desperate bet.

If the spirit stone is gone, you can snatch it again, but once the person is gone, there will be nothing.

Although this formation can't withstand too much time, it can resist the erosion of the flames for an hour, which is more than enough.

As soon as the formation came out, it was like a stone thrown into the calm lake, and the formation spread out at a speed visible to the naked eye, and finally enveloped the entire Demon Emperor City in it.

The colorful flames fell on the formation light shield, and although it burned loudly, it could not destroy the defense of the formation.

The monks who were crying for their father and mother suddenly found that as if they had entered a big house at once, those flames could not help them at all, and one by one they couldn't help but let out a sigh of relief and smiled.

"Is this a manifestation of God?"

"Is this the demon god who has made a move?"

"Thank you, God!"

"Thank you!"

They fell to their knees and bowed to the sky.

"What's going on?"

Sure enough, as Mu Zifeng expected, the moment the formation was formed, the powerhouses in the sky who were in charge of alchemy discovered that something was wrong, and they appeared one after another.

One, two, three, four, sure enough, there are four people, and they are the peak of an eighth-order Great Demon Emperor, an eighth-order Great Demon Emperor in the middle stage, and an eighth-order Great Demon Emperor in the early stage. Judging from the early stage powerhouse of the Eighth Order Great Demon Emperor, his cultivation was not very stable, and it looked like he had just broken through.

And what about the other one?

"Damn!" Mu Zifeng couldn't help but burst into a foul mouth, "That kid turned out to be ...... It turned out to be the early stage of the Ninth Order Great Demon Emperor!"

"How can this be played?" Mu Zifeng's heart suddenly raised his throat, his cultivation was the peak of the Eighth Order Great Immortal Venerable, and he was barely able to deal with the peak of the Eighth Order Great Demon Emperor, whether he could kill it or not, he didn't know the bottom in his heart.

And there was a ninth-order Great Demon Emperor here, if he was on the right side, he would only have to run away.

He had already thought that the Lord Organization was very powerful, but he never thought that it would be so powerful!

This lineup is enough to sweep any interface. If they refine the Blood Pill and create a group of Demon Emperors to dominate the three worlds of humans, demons, and demons, it will not be as simple as eating and drinking?

Suddenly, he thought of the worst possible result, if this ninth-order Great Demon Emperor made a move against his formation, it would not take much, it would not take three blows, and the formation would have to fall apart.

"No, we must kill one of them before this old thing comes to his senses and sabotage their plans!"

If you can kill all four of these people, maybe you can delay the time for the main organization to cause chaos, which is a good thing for any interface.

Thinking of this, Mu Zifeng's spiritual power moved, and the Qiankun Emperor Sword was also taken out of the storage bag by him, and the little sword was also woken up by him.

"Little sword, whether you can sabotage their plan this time, whether you can kill the Eighth Order Great Demon Emperor or not, it's up to you!"

"Master, just look at it!"

Xiao Jian's eyes were also rounded. He had never seen so many Demon Emperors, so he was very excited and looking forward to it, if he slaughtered that Eighth-Order Great Demon Emperor, wouldn't this master surpass his previous master?

Mu Zifeng didn't ink, and the immortal power was continuously injected into his hands, making both hands have a feeling of swelling, and then he stopped.

"That's you!

With a "bang", the Qiankun Emperor Sword carried the power of opening the world, and it was a sword against the peak powerhouse of the Eighth-Order Great Demon Emperor in the southeast corner.

The reason why he chose that eighth-order Great Demon Emperor peak was because the current Mu Zifeng could only cast the Qiankun Emperor Sword two or three times, and the first time was undoubtedly the most powerful, if it was directly against the person who had just advanced, it would undoubtedly be a waste.

And he was confident that if he was full of strength, even if the peak powerhouse of the Eighth Order Great Demon Emperor did not die, he would be seriously injured and lose his combat effectiveness.

Facing the four high-level demon emperors under the leadership of a ninth-order Great Demon Emperor, he must not only be able to fight, but also be able to escape.

The sword light was like a bolt of lightning, splitting the void, and everywhere it passed, even the air was evaporated into nothingness.

And that sword light was even more brilliant, like a battleship in the world, cutting through thorns and thorns, chopping waves and waves, and heading straight for the eighth-order Great Demon Emperor.

"What's the situation?"

That eighth-order Great Demon Emperor peak powerhouse felt a force that made his heart palpitate rushing towards him, and he was stunned.

Since he was promoted to the rank of the Eighth Order Great Demon Emperor, he felt that he was already standing at the top of the Demon Netherworld Continent's Monk Pyramid, and no one could hurt him anymore, so he had always looked above the top and didn't pay attention to anyone.

Even the ninth-order Great Demon Emperor early stage powerhouse, he was not very convinced.

In the past five hundred years, he has been obsessed with cultivation, and he has never participated in any actual combat at all, and his combat experience has been almost forgotten.

Now when he saw a bolt of lightning slashing at him, he was subconsciously stunned for a moment.

But in this moment, the sword light emitted by the Qiankun Emperor Sword carried a strong wind and roared.
