Under the signal of the nightingale, Luo Fei and the others walked up along the dark passage, and after facing up for hundreds of meters, the field of vision in front of them suddenly became wider, although this place was an underground world, it was extremely bright by various orbs!

Look at the buildings here like human beings, with rockeries and flowing waters, pavilions and pavilions!

"You like Terran life very much?"

Luo Fei asked with some confusion as he opened everything here.

I only heard the nightingale say faintly, "My mother is a human race!"

Only then did Luo Fei understand why traces of the human race could be seen everywhere in the world of nightingales!

"Can you accompany me to a place, I mentioned it to you before!" Looking at Luo Fei, who was a little dazed, the nightingale asked tentatively.

"What kind of place, what is there that you must go to?" Luo Fei was also a little curious, and couldn't help asking!

"Burial Demon City, where there is only killing, and the perennial killing has given it one more thing. There was a hint of longing in Nightingale's eyes as she said this, and it was clear that it was a very tempting thing for her!

"Demon Vein, I have a way to find it. ”

"You are human, maybe it won't be of much use to you, but it has a different meaning to your men, at least it can make them progress to a great level!"

Nightingale's words directly stabbed Luo Fei's vital point, with such a temptation, Luo Fei couldn't go away, at least that's what Nightingale thought.

The fact is also the same, only to hear Luo Fei say with some urgency, "Then what are you waiting for... Let's go..."

Luo Fei said this and went down to the main hall, but the nightingale threw herself into his arms and began to sob softly.

Luo Fei was speechless and thought, "This woman must have schizophrenia!"

In desperation, Luo Fei could only say a few words of comfort, after all, her father had just been killed by herself.

A day later, at the same time, Luo Fei turned into a red man, and left the Holy Demon Mountain with Han Xin and the others swaggering, and the nightingale followed closely behind Luo Fei.

Along the way, although there is no respect for the demons, they have also avoided it!

It wasn't until two days later that Luo Fei knew that the so-called Burial Demon City was nothing more than a barren plain! Luo Fei looked down from above and looked at the plain thousands of miles away, and there were stone chambers made of black stone in many places, some of which were large and some small, scattered throughout the Burial Demon City!

Killing can be seen everywhere below, maybe for the demons, this is indeed a good place to improve their strength! Just because the demons have the ability to devour, and there will be no worries, there is no realm at all!

"Here you face death if you don't raise the butcher's knife, and to survive in this adversity, you have no choice!"

Luo Fei also knew that what the nightingale said was the truth, and he no longer hesitated to say to Han Xin and the others, "No need to scruple!

As Luo Fei's words fell, Han Xin and the others let out a howl and headed straight towards the bloody scene below!

"Aren't you going, isn't it the best way for you demons?" Seeing that the nightingale was still here, Luo Fei asked with some confusion

"I hate the smell of them. ”

The nightingale's words surprised Luo Fei a little, but he was also used to this woman's eccentric personality!

Luo Fei asked again, "What about the Demon Vein, isn't that your goal?"

But I heard the nightingale say, "It's not enough!"

"Not enough, what is not enough?" Luo Fei asked with some puzzlement, and then seemed to think of something, and asked with some surprise, "Are you saying that the dead demon clan is not enough?"

"It's not enough, it seems ....... ”

Nightingale said this with an extra long knife in her hand! Just when Luffy wondered, could it be that the weapon this woman was using was a long knife? But this long knife was nothing extraordinary at first glance!

But I saw that the nightingale directly threw out the long knife and landed directly in the gathering place of the demons below!

Then I saw that the battle broke out there, and a long knife completely sparked a fight!

Just when Luo Fei praised the nightingale's good method, the nightingale flew out directly, and then all kinds of treasures were thrown down continuously, heading directly towards the place where the demons were concentrated!

For such a scene, Luo Fei couldn't arouse the slightest pity in his heart, these killings were all caused by greed, and the dead died as they deserved!

"I have a guess that your father did it on purpose..."

While watching this killing feast, Luo Fei turned to the nightingale beside him and asked!

Nightingale didn't hide it at all and said, "There are also such elements, but the years of existence in the Demon Burial City are much older than my father's!"

"Could it be that someone arranged this? like Tuofu?"

According to what Nightingale said, it is impossible for the temptation of the demon vein not to attract the attention of those bigwigs in the Demon Domain, and naturally it is impossible for it to be swallowed by the Chi Wei family alone! This made Luo Fei a little puzzled, and he couldn't help but ask!

"This is a method left by the ancestors of the Imperial Demon Clan, and there are too many prohibitions in it, and it is impossible for them to get their hands on it!" Nightingale said confidently.

"Then the other ...... of your Imperial Demon Clan. ”

Before Luo Fei could finish speaking, he was interrupted by the nightingale, only to hear her say, "The Imperial Demon Clan has always only passed on one lineage, so those brothers and sisters of mine all died at my hands!"

When the nightingale said this, there was a hint of memory in her eyes, and the whole person became a little lonely!

"What a group of brainless demons!"

Luo Fei also knew that this kind of survival of the fittest was the best way to cultivate a strong man, but it was still difficult for him to accept such a thing!

As the battle directly below became more and more intense, it could also be seen how tempting the nightingale was to take out something, and at the same time, Luo Fei also found that those dead demons were slowly sinking into the earth, no wonder it was called Burial Demon City!

With such a cumulative killing, how many corpses were buried under this burial demon city?

"Almost, call them back. ”

At this time, the nightingale's eyes showed excitement, and she went in one direction, looking a little impatient!

Immediately, Luo Fei summoned everyone to follow!

As he galloped to the middle of the Burial Demon City, the nightingale stopped!

"There can't be any demons to disturb you. At this point, the nightingale said to Luo Fei.

Luo Fei also understood what the nightingale meant, and immediately arranged for Han Xin and the others to directly turn on the slaughter mode, and quickly cleared a vacant land for dozens of miles!

Then I saw the nightingale chanting something similar to a spell in his mouth, and the whole person also made some strange movements, but after a few breaths, there was a roar from the ground, and then an altar made of white bones broke through the black soil and came out!

I saw the nightingale heading directly towards the altar! Luo Fei's gaze followed closely when he saw this! At this time, the altar was about to dissipate, but it was also Luo Fei's speed fast enough to touch the altar before it dissipated!

At the same time, he also found that he underestimated this woman too much, and it was obvious that he was being used by him again!

The moment he touched the altar, Luo Fei only felt that he had come to another world!

Here, apart from the pure demonic qi, there is only a piece of nothingness! Luo Fei could clearly feel that the further down he went, the stronger the demonic qi became!
