Yun Changsheng dragged the old man's soul and pulled him into the world of the Evil Demon Mountain under his extremely unwilling roar.

Yun Changsheng sealed the old man and the group of enemies together, threw them into the enchantment left by the old ancestor back then, and sealed them again.

Then, Yun Changsheng also joined forces with the elders to perform the Demon Sect's mysterious sealing technique to strengthen the sealing power of this enchantment and prevent it from accidentally reappearing.

"In the future, I need to come here every hundred years to inspect this place, so that they don't escape again."

Yun Changsheng commanded, this group of enemies is very tricky, they have immortal bodies, even if they are still immortal after countless years, they can't kill each other, they can only continue to seal them.

The ancestor of the Demon Sect was a generation of powerhouses in the Aragami Sect back then, and even he couldn't kill this group of people, let alone them.

After solving everything, Yun Changsheng took the elders to leave the Demon Mountain World and re-sealed the Demon Mountain World, and the pagoda was closed.

Yun Changsheng walked out of the Demon Mountain, didn't stay long, and took Chu Feng with him before leaving.

On the main hall of the Demon Sect.

"Yang Yun, you have made great achievements one after another today, let's say, what reward do you want."

Yun Changsheng said to Chu Feng.

Although he knew Chu Feng's identity, he didn't expose it.

"The juniors don't need any rewards, I just want the sect master to tell me what the origin of this group of people is."

Chu Feng hugged his fist at Yun Changsheng, he wanted to know what the identity of this group of mysterious enemies was, because this group of enemies suddenly broke through the enchantment, he still couldn't confirm whether it was really related to Chu Zhenqiong, but he still wanted to know the identity of this group of people.

When Yun Changsheng heard this, he didn't think about it deeply, thinking that Chu Feng just wanted to know.

"I can tell you their origins, you better say some rewards, lest the nameless old guy misunderstand, and think that the Demon Sect is stingy."

Yun Changsheng is more jealous of namelessness, this guy has no scruples about doing things, and his temper is also very weird.

"That'...... Just give me a copy of the exercises of the formation. ”

Chu Feng thought about it and said, he actually didn't lack anything, but recently he was interested in the formation and wanted to study it.

"Okay, I'll give it to you later."

Yun Changsheng nodded.

"Ghost Blood Feng, this time, you also made meritorious contributions, this superb spiritual weapon is given to you, this knife is called the Dragon Slaying Glaive Knife, it was obtained by the Great Elder in the ancient secret realm, it is a very good spiritual weapon."

"This knife was promised to you before, it is not a reward, this jade pendant is given to you, you can use this jade pendant in times of crisis, it can burst out with a blow equivalent to my full strength, you can save your life and kill a strong enemy."

With a wave of Yun Changsheng's robe, a dragon slaying glaive and an emerald green jade pendant flew out.

"Thank you, Sect Master."

Ghost Blood Feng knelt down excitedly, these two things were priceless, and he was very grateful.

"Improving your cultivation is a thank you to the Demon Sect, you can go back to the tribe tomorrow, and after you finish dealing with things, you will return to the Demon Sect and officially start your cultivation."

"Each disciple of the Demon Sect can bring a few servants or family members, and you can decide at your own discretion."

Yun Changsheng said, after the battle of the Ghost Blood Feng Genius, he has not returned to the tribe, and the Demon Sect is not an unkind sect, so give the Ghost Blood Feng a period of time to go back to the tribe.

Come home rich or famous.

"Chu Feng, do you remember what I said that day, now it's time for you to help me."

Yun Changsheng waved his hand to signal the blood to go down, and then said to Chu Feng.

As soon as these words came out, Chu Feng's mind quickly came up with the previous matter, before he stepped into the world of Demon Mountain, he was chased and killed by many disciples of the Demon Sect because of alchemy, and finally the sect leader Yun Changsheng promised to let him go, but he needed to help him do something.

"This matter, as long as you do it well, let alone the formation exercises, I can also promise you one more request, no matter what the requirements are, as long as I can do it."

Yun Changsheng gave a huge promise, the promise of the strongest is not something that can be obtained casually in the Eastern Wilderness.

As the strongest people, they no longer value external objects, they pay more attention to their own dignity, and they will do the promises they make even if they die in their lives.

Therefore, Yun Changsheng's promise is extremely precious.

When Chu Feng heard this, he was not too happy, but showed a suspicious look, the more things that sounded good, there must be dangers attached to them, or other unfavorable things.

"Sect Master, what is the matter?"

Chu Feng asked vigilantly.

"Come with me, and I will tell you, and I will tell you the origin of the group."

Yun Changsheng opened his mouth and left this hall with Chu Feng, and the direction he went to was the alchemy hall that Chu Feng had been to before.

Along the way, Yun Changsheng told Chu Feng the details of the group of people in the Evil Demon Mountain World.

"Those mysterious enemies are not from the Heavenly God Continent, they are the invaders of the Heavenly God Continent."

Yun Changsheng's words shocked Chu Feng's eyes wide, they were not from the Heavenly God Continent, this news was too shocking.

"Presumably your master has told you about the origin of the evil sect."

Yun Changsheng glanced at Chu Feng deeply, a decent person worships the nameless master of the evil sect, he believes that the nameless must tell Chu Feng these secrets, otherwise it is impossible for a person who has been affected by the world fabricated by the decency for many years to accept it.

"Yes."

Chu Feng said, Yun Changsheng's eyes made him secretly pinch a cold sweat, he understood that Yun Changsheng must know his true identity.

"Back then, the Aragami Sect was the largest sect in the Eastern Wilderness, and it was the only inheritance that was handed down from ancient times, but it was defeated by the invaders of the Northern Wilderness and the Western Wilderness, why is this? If it weren't for the help of this group of enemies from other worlds, those invaders alone wouldn't be able to defeat the Aragami Sect. ”

"The Aragami Sect has the inheritance left by many strong people in ancient times, and those invaders are equivalent to scattered cultivation now."

Yun Changsheng just said a few words, but there was a lot of news.

"What the Sect Master means is that this group of mysterious people came from other worlds and then intervened to help the invaders defeat the Aragami Sect, but why did they do this?"

Chu Feng was puzzled.

"This group of people, the ancestor once guessed, is very likely to be those people from the Great Thousand Worlds who attacked the Heavenly God Continent and destroyed the entire ancient era."

Yun Changsheng said in a deep voice, he also heard from his master about this matter, that is, the previous sect master of the Demon Sect.

Bang~

Chu Feng opened his mouth wide, if this group of mysterious enemies was really related to the people of the Great World, then Chu Zhenqiong ......

"Impossible, Chu Zhenqiong and his father are brothers, how can they be from the world."

Chu Feng quickly dispelled his conjecture.

"What did you find?"

Chu Feng's strange appearance aroused Yun Changsheng's curiosity.

"It's nothing, it's just that those faint demonic aura on their bodies makes me wonder."

Chu Feng shook his head, it was impossible for him to tell Yun Changsheng about this, after all, he didn't know who Yun Changsheng was.

After years of going out, he deeply knew that people's hearts were sinister, and except for a few people, Chu Feng didn't believe in anyone.

Especially an old monster like Yun Changsheng, who has lived for countless years, is extremely thoughtful, and it is not for him to figure it out.

"Demonic breath, don't you say I don't think it yet, now that I think about it, it really has a bit of demonic taste."

Yun Changsheng frowned slightly, but suddenly, his mind flashed about the group of enemies who had set off a bloody storm in the righteous sect and finally fled into the realm of the evil sect, that group of enemies, the demonic aura was monstrous.

And this group of enemies sealed by the Ancestor, although the demonic aura is not strong, they are very similar in nature.

"If they deliberately exude a demonic aura, it is likely to be the same as theirs."

Yun Changsheng's pupils suddenly shot out of essence, and at this moment, he felt that he had vaguely guessed a clue, this matter was ...... I'm afraid it's not easy.

"Chu Feng, you wait for me in the Alchemy Hall."

Yun Changsheng's face changed, if this matter was really as he expected, then in the Eastern Wilderness, maybe there would be a big change.

Chu Feng didn't know what was going on, but he didn't ask much.

Yun Changsheng flew into the Demon Mountain World, went deep into the depths of the world, and stood in front of the group of enemies who were sealed by the enchantment.

"Unleash your strongest demonic energy, otherwise don't blame me for being unkind."

Yun Changsheng ordered this group of mysterious enemies.

"Haha, you said release us?"

"."

The hatred of this group of people towards Yun Changsheng was monstrous, how could they listen to him.

"Huh"

Yun Changsheng sneered, and then in the Demon Mountain World, there were screams of pain, these screams were so miserable that people's scalps tingled when they heard them.

The group of people who were sealed by the enchantment fell to the ground one by one and spit out black smoke, while Yun Changsheng held a jade bottle in his hand, and the jade bottle contained the rich demonic qi released by this group of people.

Yun Changsheng smelled this demonic aura, and then remembered his doppelganger, the demonic aura he sensed near the Heavenly Demon Abyss before, it was indeed from the same origin.

"Are they making waves?"

Yun Changsheng left the Demon Mountain World with a jade bottle full of demonic energy, and he was going to discuss this matter with the sect masters of the other three major sects.

However, before that, Yun Changsheng still had to deal with one more thing, and that was to ask Chu Feng for help.

Yun Changsheng flew to the Alchemy Hall, Chu Feng came to the Alchemy Hall one step ahead of him, and as soon as he arrived on his front foot, the group of Heaven-level alchemists rushed to get the news and continued to be courteous, hoping that Chu Feng would give them alchemy again and demonstrate the process of controlling the spirit gathering.

The Alchemy Hall is an important place in the Demon Demon Sect, there are not only heaven-level alchemists, but also some weaker alchemists, they see the heaven-level alchemists who were high up in the past and unspeakably expensive, they all shouted Chu Feng's seniors, and that flattering face simply made their concept of these heaven-level alchemists change drastically.

"A few masters, I really don't have time today, the sect master asked me to wait for him here, saying that there is something important for me to help."

Chu Feng shrugged his shoulders, he still didn't know what Yun Changsheng had done when he asked him to come to the Alchemy Hall.

When several Heavenly Rank Alchemists heard this, they didn't pester him, but they were also very curious about what the sect wanted Chu Feng to help.

What is it?
