I, the deposed prince, signed in the imperial mausoleum for a thousand years

"Ding! Congratulations, Master, you have obtained the Domain: Nine Nether Hells!"

Hearing the notification sound from the system, Qin Feng was startled for a moment, and then said: "Is this the domain that the number one demon king uses?"

When he fought against the first demon last time, he was curious about how to cultivate that domain, but he didn't expect to sign in here and get this domain.

Then Qin Feng checked the information in this field.

He was surprised to find that the Nine Serenities Hell was far more than the simple one that the first demon king displayed, it was a powerful domain absolutely comparable to the pure land of Buddhism.

After the Nine Serenity Hell has been cultivated, it can reflect the scene of the whole hell.

And everything in hell can be dispatched at will.

"Could it be that I can let Black and White Impermanence, or even Yama of the Ten Palaces, help me kill the enemies in the domain?"

Qin Feng was surprised and said: "This is a bit too strong!"

Thinking of this, he couldn't help looking forward to it.

Although the Buddhist Pure Land is powerful, even if it is cultivated to a great extent, it is far from being as shocking as the Nine Nether Purgatory.

Immediately, Qin Feng chose to merge with Nine Nether Hells.

Suddenly a large amount of information entered into his spiritual space.

Incredibly amazing.

"What is the master looking at?"

Bu Youxuan, who was next to him, saw Qin Feng standing still, and asked suspiciously.

"It's nothing."

After merging the cultivation method of the Nine Nether Hells, Qin Feng shook his head, and then said: "The treasure house of the first demon king should be in front, and there should be a lot of good things in it.

Check it out. "

"kindness."

Bu Youxuan nodded.

The two of them then walked towards the treasure house.

Just like the treasury of the tenth Demon King of the Demon Flame Sect, there are also all kinds of natural and earthly treasures in the treasury here, which makes people dizzy.

After all, the first demon king has ruled the entire trial ground for so many years.

But as long as he wants any natural treasures born in the world, no one dares to snatch them from him.

"With so many such rare cultivation resources, it's no wonder that the number one Demon King's cultivation has always maintained a huge gap with other Demon Kings."

Bu Youxuan looked at the various ancient medicines in the treasure house that were full of aura and exuding a faint light, and couldn't help but said.

It just dazzled her.

However, after Qin Feng saw the items in the treasure house, he was rather disappointed.

Even though there are so many cultivation resources, even a strong man in the Tiangang realm will definitely find it hard not to be moved.

But to Qin Feng, there was no attraction. After all, he did not lack any cultivation resources.

Even, the sum of these treasures of heaven, material and earth is not as attractive to him as the half-broken arrow of the holy weapon in the tenth devil's treasure house.

But something is better than nothing.

Qin Feng gave in to Youxuan and collected all these cultivation resources. After returning, he could give them to the monsters in the nine-story demon tower.

"kindness?"

Suddenly, Qin Feng looked at a direction completely opposite to the location of the treasure house, and murmured: "There is a special formation wave, which appears and disappears from time to time."

Immediately, he flew in that direction.

Bu Youxuan followed closely behind.

Not long after, Qin Feng and Bu Youxuan came to the deepest part of the entire huge building complex.

There is a very grand and ancient palace here.

The gate made of black gold is a full twenty feet high. Standing in front of the palace, it looks very small.

The material of the entire palace is very special, which can hide the formation and energy fluctuations inside.

Rao is based on the strength of Qin Feng's spiritual consciousness, and it is difficult to find it if he does not perceive it seriously.

"Crash..."

Qin Feng didn't waste any time either. When he got to the gate and pushed it fiercely, the Wujin gate engraved with patterns was smashed into pieces and scattered all over the ground.

As if made of mud.

And as the Wujin Gate in front of him collapsed, the scene inside also appeared before his eyes.

The whole palace, no matter on the ground or on the surrounding walls, are engraved with ancient and mysterious formation patterns, which at first glance are of extraordinary rank.

And in the center of the entire palace, there is an extremely deep shaft with a diameter of about four to five feet.

The magma at the bottom of the shaft was tumbling, and in the sky above was a palm-sized diamond-shaped crystal suspended in mid-air.

It can be clearly seen that the rhomboid crystals are used to absorb the energy in the magma and provide it for the operation of the formation here.

"What is it here for?"

After checking the scene here with the divine pupil, Bu Youxuan said in a puzzled way.

Although she has divine pupils, she doesn't know much about formations.

So after reading it, I don't understand the purpose here.

"This place should be the core of a formation."

Qin Feng said slowly: "If I'm not wrong, the function of this formation is to help the number one demon king and the others leave this world."

However, he could clearly see that the formations here were obviously not all.

In other places in this world, there should be quite a few formations that echo this core formation.

Moreover, the energy absorbed in this rhomboid crystal is far from enough to operate the entire formation.

"So it is."

Bu Youxuan suddenly realized.

At the same time, I was shocked.

It's hard to imagine how powerful the full version of the formation arranged by the first demon king is, and it needs the magma in the earth's core to provide energy.

Qin Feng doesn't care much about the formation here, because he has the abyss scroll, which allows him to travel easily between the world and the world.

But the fiery red rhombic crystals caught his attention.

"This crystal can hold such a majestic energy, it seems to be a very good material."

The first demon king must have been letting the diamond-shaped crystal absorb the hot energy in the center of the earth from the beginning of the preparation plan, but after so many years, the rhomboid crystal has not been filled.

It's hard to imagine what grade material this rhomboid spar is made of.

I'm afraid, it's enough to cast holy artifacts.

"Shh!"

Thinking like this in his heart, Qin Feng was not polite, and directly grabbed the diamond-shaped spar from the air.

After carefully feeling the energy contained in it, he felt even more satisfied, and casually put it into the system space.

And the formation in this palace, after losing the energy supply, suddenly couldn't work, and began to collapse, and the whole palace was crumbling.

Qin Feng grabbed Bu Youxuan beside him, and in an instant, he left the palace and came to the sky.

"Boom..."

At the same time, the palace collapsed, billowing with smoke and dust.

The hard work of the top ten demon kings for so many years was wiped out at this moment.

It also symbolizes the complete end of this world, an era.
