Three days later, the sixth heaven.

In the Sixth Heaven, except that the immortal spirit qi was a little stronger than the Fifth Heaven below, Guan Yu didn't see anything special, and he didn't feel any difference between this place and the First Heaven.

Naturally, Guan Yu also looked at Nangong Qianqiu with admiration at this time, because he and Nangong Qianqiu came directly from the First Heaven to the Sixth Heaven.

Nangong Qianqiu just swiped casually, and a spatial passage appeared, directly breaking through the two-fold three-fold fourfold five-fold heaven, and when the two of them jumped into the space passage, they also directly drove into the sixfold heaven.

This kind of strength is very terrifying, too scary.

Guan Yu already knew in advance that except for the Nine Heavens, every Heavenly Rank was actually mixed, there were ordinary Heavenly Immortals, there were also high-level Immortal Kings, and there were even Immortal Emperors living in various Heavenly Positions.

It's just that Yuan Ling'er can't figure out why she wants to separate these heavy heavens?

"Teacher, why is there a division of the Nine Heavens? In these Nine Heavens, apart from the difference in the immortal qi, is there any other difference?" Guan Yu and Nangong Qianqiu were flying in the sky of the Six Heavens at this time, and he didn't know where he was going.

"Actually, the Nine Heavens are not only a celestial position that can be inhabited, but also a division of the realm. ”

"What do you mean?" Guan Yu said blankly.

"For example, in the Heavenly Immortal Realm, you can only break through one or two layers of heavenly barriers, and you can only enter the second or triple heaven from one heaven!"

"But when you get to the Golden Immortal Realm, you can break through the three or four barriers. ”

"Da Luo can break through five or six layers of barriers, Immortal King has seven layers, Immortal King has eight layers, and Immortal Emperor can break through nine layers. ”

"This is the division of strength, the Immortal Emperor can go directly to the First Heaven or directly to the Nine Heavens. ”

"Besides, in fact, the Nine Heavens are just a name, the Nine Heavens are all equal heavens, parallel heavens, no other, but the aura is different, and later it was gradually divided into rules by the strong. ”

"I understand, but I heard that only the Immortal Emperor can go to the Nine Heavens?" Guan Yu said curiously.

"This is true, the barrier of the Nine Heavens is particularly thick, and only the Immortal Emperor can break through it. ”

"Is the Nine Heavens the same as the other Heavenly Ranks?"

Nangong Qianqiu shook his head: "It's different, okay, don't ask so much, we've arrived." At this moment, when Guan Yu looked ahead, a fairyland-like fairy palace appeared in his sight.

The fairy palace is on a mountainside, like a dream, mountains and waterfalls, small bridges and flowing water, and cranes have children.

When Guan Yu and the others flew over, a boy riding a black and white crane greeted him, and the boy was only twelve or thirteen years old.

"Zhi'er has seen the emperor. The boy jumped down from the black and white crane, fell to his knees, and bowed!

Guan Yu smacked his tongue, the old man of Nangong really had a style.

"Well, your master is here?"

"Zai, the master came back two days ago, and has been waiting for Emperor Hou. The boy said again and again.

"Okay, lead the way. ”

"Yes, please come with Weaver. The boy sat down and made a gesture of please, and then rode the crane again to lead the way, and after passing through the faint clouds and mist on the top of the mountain, he fell into the fairy palace halfway up the mountain.

"Haha, congratulations to Brother Nangong for getting a good apprentice. A hearty laugh came, and a man like Zhang Fei also strode out of the side hall.

The man was almost two meters tall, with a black beard on his face, eyes like brass bells, and hands like small grinding discs.

"Big black man, you know the old man's temper, let's start. Nangong Qianqiu put her hands behind her back, arrogant like a rooster.

"Yes, yes. After the big black man nodded again and again, he suddenly threw out a bead and threw it to Guan Yu: "Take it, gadget." ”

Guan Yu hurriedly put it away, and bowed: "Thank you, senior." "This is a meeting gift, and people gave it to him after seeing Nangong's face, but he didn't know what it was.

"Hehe, big black man, don't fool my apprentice with ordinary gadgets, we don't want food. Nangong Qianqiu didn't appreciate it at all, and still kept a straight face.

"How dare you, how dare you, my brother. The big black man smiled bitterly: "That's my Xuan Mingzhu, okay?"

"Oh?" Nangong Qianqiu's eyes lit up, and then nodded with a smile: "It's about the same, thank you again for being a black senior." ”

"Yes, thank you. ”

"No, no, my brother came over and helped me a lot, just a little gadget. The big black man waved his hand.

While the three of them were talking, they walked to a rock wall in the fairy palace, and then the rock wall flashed brightly, and a portal was opened, and the three of them walked in.

In the portal, there is a cave, it is actually a small world, about the size of a football field, with a house, a grassland, and a few ancient trees.

"Okay, give me the materials, you go out, you will be out of the customs in half a month, and no one will disturb you." ”

"Good. The big black man said hello twice, handed Nangong a ring, and walked out.

As soon as the big black man walked out, Nangong Qianqiu said: "The big black man's real name is Heiyan, a first-class immortal emperor, the old man lost a bet with him two thousand years ago, so he promised to help him refine the pill once, and this time is the time to exchange the promise." And you also have to remember that not everyone can be moved, and sometimes, even if someone holds a knife around his neck, he can't give him alchemy, we have to have our arrogance. ”

"Yes, the disciple wrote it down. ”

"Then the Xuan Mingzhu, you take it well, the Xuan Mingzhu is a cave pearl, and after the sacrifice, it is included in the body, and it is a small world inside, which is the palace of the big black man. ”

"Dongzhu?Small World?" Guan Yu's eyes lit up, and he suddenly remembered the Kowloon Walled City back then, and the Kowloon Walled City should also be a small world, right?

"Okay, I'm going to start alchemy, and you have to pay full attention and don't be distracted. As he spoke, the old man of Nangong waved his sleeves, and a huge Ding furnace appeared in front of the two of them, standing directly on the grassland.

He didn't know what kind of material his furnace was made of, with a kind of quaint breath.

The old man Nangong also sat down immediately, and with his mouth open, a flame erupted.

It's not Samadhi true fire, but purple flame, which should be a kind of different fire, and Guan Yu doesn't know what kind of fire it is.

At the same time, his two hands were picking out the medicinal materials, and he was not idle, and after the medicinal materials were sorted, he pointed with his left hand, and the purple flame also shot out, and at the same time closed his mouth, and said, "Can you guess what kind of pill the big black man wants to refine?"

Guan Yu glanced at the medicinal herbs that had been picked out and said, "It should be the elixir of the Tribulation, right?"

"Not bad. Nangong said with a touch of appreciation in his eyes: "It's Du Erdan, you also have Du Erdan in the mortal plane, right?" But the materials are different, and the refining methods are also a little different, especially the control of the fire is more demanding, the big black man has been stuck in the first-grade Immortal Emperor for many years, and he has not dared to cross the catastrophe of the second-grade Immortal Emperor, waiting for the old man's taste to cross Erdan, so sending a small hole bead is nothing, what treasure you want in the future, countless people will give it to you. ”

"Let's see that I start refining, this first medicine, you must put the dragon bone grass......" Saying that, Nangong threw an herb into the furnace, and explained the control of the fire, the time of refining, etc., all of which were very strict, and there must be no sloppiness.

Guan Yu was already very talented in alchemy, so he was immediately fascinated.
