"You...... How did you do it!" The corners of the Nine Shadows Demon Emperor's mouth trembled, and he looked at Qin Feng as if he had seen a ghost.

This is the artifact of the Heavenly Demon Palace, but at this moment, it is in the hands of a young man, and he is very happy.

This demon beast Purple Emperor Sword's brain twitched, and he left with Qin Feng, and it was too late for the Heavenly Demon Palace to cry.

"Young Master Qin, you see that this Sword Venerable is the supreme treasure of my Heavenly Demon Palace, can you ......" The Nine Demon Emperor looked at Qin Feng, and even changed his tone, calling him Gongzi.

"I know this, don't worry, Demon Emperor. Qin Feng said lightly.

"Okay, it's not good for you to be away from the altar for too long, go back early. Qin Feng stroked the Purple Emperor Sword as if he was talking to an old friend for many years.

The Purple Emperor Sword let out a sword roar, obviously a little unhappy.

"Be obedient, or I'll be angry, and I promise you that I'll come back to see you when I have time. Qin Feng said.

Zheng!

The Purple Emperor Sword finally reluctantly turned into a sword light and disappeared into the depths of the Heavenly Demon Palace.

The three sages of the Heavenly Demon Palace looked at this scene and breathed a sigh of relief.

"Qin Gongzi, I think we should talk. The Nine Demon Emperor looked at Qin Feng and said.

"Today's matter, no one is allowed to spread it, otherwise the cultivation will be abolished and the soul will be refined!" The Nine Demon Emperor gave an order and disappeared from the spot with Qin Feng.

Nangong Yue and Zhu Fei looked at this scene, a little worried in their hearts, but they couldn't help much.

Hanging island, in the middle of the palace.

The crowd appeared in the palace.

"Young Master Qin, I want to know, how did you communicate with Sword Venerable?" the Nine Demon Emperor asked.

"I don't know about this, it's just that the good guy was almost killed, and it is estimated that the Purple Emperor Sword will only make a move when he sees that I have been wronged. Qin Feng said lightly, his tone a little indifferent.

When the Nine Demon Emperor heard this, he looked at Zhu Baijian.

"The palace master is angry, it is because I am not strict in discipline, Shi Yan ran to Qin Feng to avenge the killing of his brother, and was killed by Qin Feng, I was also angry for a while, and I lost my mind before I made a move. Zhu Baijian hurriedly knelt down, cold sweat streaming down his forehead.

"Hmph! Are you a fool to me, or are you a fool! Remembering the merits you have made for the Heavenly Demon Palace, abolishing your hundred-year cultivation as a warning, suppressing it for a hundred years under the Hanging Island, and the position of the Heavenly Temple Hall Lord is temporarily represented by the eldest grandson!" A black light shot out between the Nine Demon Emperor's words, and Zhu Baijian let out a miserable scream, and the cultivation of his whole body began to regress.

Abolishing his hundred-year cultivation is to behead him for a hundred years, although he is still in the Venerable realm, but if he wants to cultivate back, then it will take at least a few decades.

Not long after, Zhu Baijian was soaked with sweat all over his body, but he knelt on the ground and didn't move.

With a wave of his right hand, the Nine Demon Emperor burst out of the Great Dao Divine Pattern on the ground, pulling Zhu Baijian and sinking him into the ground.

From beginning to end, Zhu Baijian did not dare to beg for mercy again.

Because he knew that if it weren't for his status, he would have been gone away at this moment.

"Young Master Qin, you are satisfied with the result of such a treatment. The Nine Demon Emperor looked at Qin Feng and said.

"The Heavenly Demon Palace's own affairs, I am inconvenient for outsiders to interfere, but I don't want Fei'er to be wronged in the Heavenly Demon Palace in the future, otherwise I don't mind overturning the Heavenly Demon Palace. Qin Feng said lightly.

The three palace masters, when they met, an ant who turned into a spirit realm actually said in front of them that they were going to overthrow the Heavenly Demon Palace, but they all knew that once Qin Feng was reckless, then the Purple Emperor Sword would definitely not stand on the side of the Heavenly Demon Palace.

Even if the three great sages attacked at the same time to destroy the Purple Emperor Sword, it would be too much loss for the Heavenly Demon Palace.

"This is my negligence, I will order that I canonize Fei'er as the princess of the Heavenly Demon Palace, announce it to the world on a certain day, and teach her personally, you see. The Nine Demon Emperor said.

"That's very good, I can also tell the palace master that the Purple Emperor Sword is still from the Heavenly Demon Palace, and no one will take it away. Qin Feng said.

He had already seen that for countless years, the Heavenly Demon Palace had formed a formation with the entire Heavenly Demon Mountain Range, and the core of the formation was really the Purple Emperor Sword.

The Purple Emperor Sword is warmed by the Heavenly Demon Mountain Range on weekdays, and it has been integrated with this formation, so once it is taken away, it will not be good for it.

Hearing Qin Feng's assurance, the three palace masters finally breathed a sigh of relief, but Qin Feng didn't tell them how to communicate with Sword Venerable, since Qin Feng was unwilling to say this kind of thing, then they wouldn't force it, as long as the Purple Emperor Sword was still in the Heavenly Demon Palace.

"By the way, the palace master, I don't know when the palace master will send troops to Yuding Gate. Qin Feng asked.

Think about the time, if the Situ family makes a move, they are also rushing to the Yuding Gate, so they can't be delayed.

"This, Qin Gongzi, it's not that we don't want to make a move, but we ourselves have encountered great trouble. The Nine Demon Emperor said.

"Trouble?" Suddenly, Qin Feng smelled an extremely disgusted aura from the Nine Demon Emperors.

"But what happened to the Underground Ancestral Vein Seal?" Qin Feng's face changed.

"How ....... you know about the Underground Ancestral Vein Seal!" The Nine Shadows Demon Emperor's face changed.

The seal of the underground ancestral vein of the Heavenly Demon Palace was a secret, and except for the people above the elders, no one else knew about it at all.

And now a disciple of the Jade Ding Sect said it, how not to shock them.

"If I say that I am the next generation descendant of the Purple Sword Demon Emperor, do you believe it or not?" Qin Feng said.

"It doesn't matter how I know, it's important that I know how to solve this problem. Qin Feng said lightly.

"How can we trust you?" The Purple Sword Demon Emperor looked at the young man in front of him and found that he couldn't see this young man clearly at all, and this young man's whole body exuded an evil nature.

"You can only believe me, if you can solve it, then it will be solved a long time ago, it is better to take me to have a look, maybe it will be too late, otherwise you also know that if you let the things inside escape, I am afraid that the entire Heavenly Demon Palace will turn into a piece of demonic land. Qin Feng said.

The three sages met and communicated secretly, and finally decided to take Qin Feng with them.

"Okay, we can take you there, but that place is very dangerous right now, so you have to be prepared. The Nine Demon Emperor said.

"Lead the way, it's just that my friend is still in the Heavenly Demon Palace, and I don't want her to be hurt. Qin Feng said.

"This is simple, I will immediately send someone to deal with it, and treat it with the highest VIP treatment. After the Nine Demon Emperor finished speaking, he gave the rumor to Zhou Xian and asked him to deal with it.

Then the three sages took Qin Feng through the air and came to the deepest part of the back mountain of the Heavenly Demon Palace.

On the top of a mountain, as if an abyss left by a volcanic eruption, the Nine Demon Emperor took Qin Feng to the abyss.

In the abyss, there was a trace of gray mist at this moment, and the trees withered instantly.

Qin Feng looked at the slightest gray mist, and his face was a little ugly.

Things are more serious than imagined.

He naturally knew what was in it, and it was he and the Emperor Hengtian who sealed this place in the first place.

That battle was earth-shattering, almost breaking through the ground, and finally won by luck, and completely sealed this place, but I didn't expect that countless years had passed, and the original seal had broken a little.

"Be careful, we're going underground. After the Nine Demon Emperor finished speaking, the whole body of light burst out, and the power of the Great Dao enveloped him, rushing down towards the abyss.

The light became darker and darker, and the gray mist around them became thicker and thicker, and finally after a stick of incense, several people came to an underground space.

In front of them was a kilometer-long vine that radiated a milky white glow. The vines are extremely thick and intertwined, this is the spiritual root of the earth's veins transformed by the ancestral veins of the Heavenly Demon Palace.

It's just that at this moment, above the earth's leyline spirit root, there is a trace of gray mist.

Originally, there should have been a lot of heavenly and earthly treasures growing on the spiritual roots of the earth veins, but they were all withered at this moment.

In the distance, dozens of Elder Hall Masters of the Heavenly Demon Palace were forming a formation, suppressing a stone gate above the spiritual root of the earth vein.

The terrifying gray mist emanates from it.
