Since Lu Xuan has decided to practice in the secret realm of Yujing, he must set a suitable place for his own cultivation.

This underground fire vein is also not an extraordinary fire, and it is unique to cultivate the Yi Bone Sutra here, but the White Bone City of Xuanzhen Saint Venerable is actually called Yin Ji City, but it is a place where the Yin Qi is extremely strong, and it is not suitable for Lu Xuan to practice here.

So Lu Xuan planned to find a place far away from the White Bone City to open a cave mansion, which could be regarded as a cultivation place for himself. As for the other cultivation place, Lu Xuan planned to go to the sea to find a desert island, which had both water-based aura and divine soul power, which was suitable for him to cultivate the true technique of the jade pool and temper the divine soul.

However, Lu Xuan was not in a hurry to leave the Cathode City, but asked the Xuanzhen Holy Venerable about the origin of the Cathode City.

After the explanation of the Xuanzhen Holy Venerable, Lu Xuan knew that the two great cities of Yin and Yang in Bai Yujing had their own magic. Needless to say, Anode City is made from the bones of countless demon beasts. In ancient times, there were constant disputes between the two clans, and the strong men of Bai Yujing had killed many powerful demons, and finally refined this cathode city.

The power of Yin Ji City is extremely powerful, and when the Yin Qi is at its peak, even the Twelve Rank Demon Emperor has to flee when he hears the wind. Therefore, the ghost cultivator Cui Huai once said that the cathode city is Bai Yujing's biggest and strongest magic weapon, and it is also Bai Yujing's guardian formation.

If it weren't for the fact that the Xuanzhen Holy Venerable was extremely weak and difficult to exert the strength of Yin Ji City, it would not have been possible for those Netherworld Heavenly Puppets and Blood Demons to use those black diamond-shaped magic weapons.

That diamond-shaped magic weapon was a magic weapon specially used by Netherworld Heaven to capture realm spirits, and it was naturally effortless to deal with an incomparably weak realm spirit like Xuanzhen Saint Venerable.

If it weren't for Lu Xuan and the others sacrificing their lives and forgetting death, the Xuanzhen Holy Venerable and the entire Xuancang World would probably be in great trouble.

After Lu Xuan heard the origin of Cathode City, his heart moved.

He called Cui Huai out first. This old ghost had also fought hard before, and he insisted on protecting Lu Xuan to break through the front of the Netherworld puppet. When Lu Xuan returned to the Resting Furnace to avoid the limelight, he retracted the Colorful Skylight Mirror, and only now did he summon it.

Cui Huai saw the Xuanzhen Holy Venerable, but his face was full of confusion.

Although the Xuanzhen Holy Venerable is famous all over the world, few people know his true identity. He has always been formless and substantial, and he only suddenly appeared in the Netherworld, and when the whole world was on the verge of destruction, he once manifested his human body to rebel against the Netherworld. Therefore, the talents of the ancient era would compare the Xuanzhen Saint Venerable with the Lingxiao Immortal Emperor and the Golden Dragon Duobao Demon Emperor.

However, there are very few people who have seen the Xuanzhen Holy Venerable, and Cui Huai has been imprisoned in the Bronze Pavilion before the invasion of the Netherworld, so he has not even heard the name of the Xuanzhen Holy Monarch.

"Holy Venerable, can you let this ghost cultivator Cui Huai practice here?" Lu Xuan said.

Cui Huai was inexplicably excited when he heard this, as soon as he came out, he felt the rich yin and evil aura in this cathode city, and being able to practice in the cathode city was a unique blessing for ghost cultivators. He looked at the Xuanzhen Saint Venerable with all his expectant eyes, for fear that he would refuse.

Xuanzhen Shengzun smiled indifferently: "I have no choice, if you leave him, you can also be a companion for me." ”

"Don't thank Xuanzhen Saint Venerable?" Lu Xuan said to Cui Huai, and Cui Huai hurriedly thanked him.

Lu Xuan said again: "It's cheap for you to let you practice here, but you also have to help me do something." ”

"Though the Lord commands. Cui Huai said respectfully.

With one move of Lu Xuan, a small black banner appeared in his hand, and it immediately turned into a dark cloud, and above the dark cloud, a huge ghost king boundary monument flashed out.

Cui Huai was suddenly startled, he had never seen such a thing as the Ghost King Boundary Monument, but he could feel the endless yin qi contained in it. This thing has a natural allure for ghost cultivators, and Cui Huai couldn't help but ask excitedly, "Lord, what kind of magic weapon is this?"

"This thing is called the Ghost King Boundary Monument. ”

Lu Xuan pointed to the three figures on the Ghost King Boundary Monument, "Those are my three friends, the one above is named Li Wuxin, and the two below are Xiao Wushu and Ge Lin." They all fell in the fierce battle, leaving only a wisp of remnant soul to be included in the Ghost King Boundary Monument. Since you have also cultivated from a wisp of remnant soul to the Cave Void Realm, there should be a way to help them wake up, right?"

Cui Huai said eagerly: "Can the old slave go in and have a look?"

Lu Xuan naturally nodded in agreement.

Cui Huai turned into a black gas and entered the Ghost King Boundary Monument, and after a while, he returned, and said in ecstasy: "Lord, there is a world in this Ghost King Boundary Monument, which contains a kind of soul-calming divine light, as long as the remnant soul divine light is not extinguished, it can ensure that his spiritual sense is not extinguished." Those three people are fine, as long as they cultivate the old slave's ghost cultivation method, they will be able to wake up one day. ”

Lu Xuan suddenly breathed a sigh of relief, "Then I'll leave this matter to you." ”

Cui Huai nodded repeatedly.

Being able to practice in Cathode City already made Cui Huai overjoyed, but this Ghost King Boundary Monument brought him even more surprises.

You must know that when he came to Bai Yujing, he wanted to steal an immortal relic to resist the upcoming Cave Void Tribulation. But now that the immortal relics no longer exist, the heavenly tribulation has become Cui Huai's biggest concern. However, now that there is a Ghost King Boundary Monument, Cui Huai can go to the Ghost King Boundary Monument to keep the last trace of spiritual consciousness even if he fails to cross the catastrophe, and at least there is a way out.

This succession of good things made Cui Huai feel a feeling for the first time.

I seem to be following the right master......

............

A year passed in a flash.

The environment in the Yujing Secret Realm is indeed unique, and Lu Xuan's cultivation has also directly risen from the early stage of fusion to the peak of fusion.

When Lu Xuan felt that he had touched a certain boundary, he went to find the Xuanzhen Holy Venerable.

"Holy Venerable, this Jade Jing Secret Realm can only accommodate the existence of the Refining and Refining Qi Realm, if I cultivate to the heart stage, will I have to go out?" Lu Xuan asked with some excitement.

Xuanzhen Saint Venerable said: "The restrictions in this secret realm were originally set by the Lingxiao Immortal Monarch, and the purpose was to facilitate the selection of candidates for the realm. But now that the realm has appeared, this restriction naturally no longer exists. Look at him......" Xuanzhen Saint Venerable pointed to the immortal tree outside the White Bone City and smiled.

The immortal tree never left the underground fire vein, and the fire vein was helpless against it.

The Eagle King's people do not seem to be afraid of fire, and still live in the canopy of the undead tree.

The Xuanzhen Holy Venerable is referring to the Eagle King.

Lu Xuan glanced over, but saw that the Eagle King was so angry that he didn't know when he had become a six-rank demon!

Hell yes.

Although Lu Xuan knew that the Eagle Boss was talented, he didn't expect his realm to improve so rapidly, compared to him, he reached the peak of fusion within a year, but it was too insignificant.

The eagle boss rattled strangely, as if he was laughing at Lu Xuan.

Although Lu Xuan knew that the Eagle King had always been suppressed by the power of the Yujing Secret Realm, so the realm was not high, and today's rapid progress was actually a thick accumulation. But being ridiculed by an eagle was not in a good mood after all, so Lu Xuan had no choice but to continue cultivating with his head bored, and then talk about crossing the fusion period first.

One day, the boundary of the fusion period was finally broken through by Lu Xuan, and a cloud of calamity quickly appeared in the sky above the secret realm.

"Twelve Heavenly Tribulations?"

The Xuanzhen Holy Venerable didn't know when he was able to walk out of the White Bone City, look up at the sky, and smile to himself.

He naturally knew the strength of the celestials, and if it weren't for the withering of the celestials, the demon clan in the ancient period would not have been able to suppress the human race. It's just that the Xuanzhen Holy Venerable has been trapped in the secret realm of Yujing before, and he doesn't know anything about Lu Xuan's past except for sensing Lu Xuan when Lu Xuan repaired the twelve-story building.

Unexpectedly, Lu Xuan actually had the appearance of a celestial man.

However, this catastrophe was far more terrifying than what Lu Xuan had experienced before.

This is the Heavenly Tribulation that ascends from the Fusion Period to the Heartbeat Period, and it is also the Heavenly Tribulation that crosses the Refining and Refining Qi Realm to the Refining and Refining God Realm!

So Lu Xuan was almost tortured to death by this heavenly tribulation.

But in the end, he survived.

Xuanzhen Saint Venerable watched with great interest as Lu Xuan resisted the Heavenly Tribulation, and finally succeeded in breaking through to the early stage of heartbeat. Although Lu Xuan was exhausted, he quickly regained some strength.

Lu Xuan immediately began to monitor himself.

The True Element and the Divine Soul have grown tremendously at the same time, especially the Divine Soul has grown the most rapidly. The Langxiao Peak of Jiufeng Mountain has long been lush, and it seems that the day of awakening the Langxiao Emperor is not far away.

Let's take a look at the dantian.

The flame of the Realm Spirit Seed had become much stronger than it had been a year ago, and it was no longer dying.

And the cultivation seed had already bloomed, and above the white flower, two clusters of light flashed out. The two rays of light were divided into black and red, as if two hearts were throbbing.

This is a symbol of the heartbeat period.

In this realm, the monk's yearning for the Great Dao becomes stronger and stronger, and the confusion of the path of cultivation arises, and in this realm, the monk's emotions are also the most colorful and difficult to contain.

Lu Xuan already had distracting thoughts, but at this time he couldn't help it anymore.

Only then did he see the Xuanzhen Saint Venerable.

"The Holy Venerable has been able to get out of Cathode City?" Lu Xuan said in surprise.

Xuanzhen Saint Venerable smiled, "You are practicing, and I am naturally not idle." ”

Lu Xuan smiled, "Holy Venerable, when can I leave the Xuancang World?"

"You practice here for one day, but you can go to the outside world for five days, why are you in a hurry to leave?"

Lu Xuan hesitated for a moment, and then told Chu Linglong about it.

Now that a full year has passed since Chu Linglong's accident, Lu Xuan has been worried for a whole year, and now Chu Linglong doesn't know what the situation is, how can he practice with peace of mind?

"I see, it's just a trivial matter. Xuanzhen Saint Venerable smiled and said, "If you want to go see her, I will take you to see her." ”

Lu Xuanzheng was stunned spontaneously, but he saw Xuanzhen Holy Venerable blinking, and the light in his eyes suddenly seemed to be a vast universe, enveloping Lu Xuan in it.

Suddenly, a wisp of Lu Xuan's divine thought was taken by the Xuanzhen Holy Venerable to a world of birds and flowers.

It is a lofty mountain full of fairy spirits, everywhere the mountains are stacked, the aura is steaming, and many colorful fairy birds are soaring in the spirit clouds, sending out a clear cry.

Where is this?

Lu Xuanzheng was confused, and he heard the voice of Xuanzhen Holy Venerable.

"This is Qishan. ”

Lu Xuan was suddenly surprised and delighted, "The Holy Venerable can already see the situation in the outside world?"

A year ago, the Xuanzhen Saint Venerable was still trapped in the Cathode City, and the spiritual sense could not travel the world as in ancient times, who knew that in just one year, the Xuanzhen Saint Venerable not only walked out of the Cathode City, but even recovered a little bit of his former supernatural powers? Sure enough, the Xuanzhen Saint Venerable smiled and said: "It is precisely because you have repaired the Twelve Stories Floor that I will recover quickly, and now the aura in the world is also much stronger." ”

"However, although I have recovered some of my magical powers, the reason why I was able to bring you to Qishan is because Qishan is also in the Great Zhou Heavenly Refining Immortal Array. ”

"The Great Zhou Heaven Refining Immortal Array is based on the human cultivation method and is refined, so there are also upper dantian, middle dantian and lower dantian. Ten thousand years ago, after the Lingxiao Immortal Monarch refined into the Great Zhou Tian Refining Immortal Array, the aura around my three dantians was extremely strong, so many immortal sects gathered around the three dantians. ”

"The upper dantian is the secret realm of Yujing, the surrounding sea of stars is formed, the middle dantian is surrounded by Xuanhuang Mountain, and the lower dantian is the dragon and tiger land. This Qishan is in the middle of the dragon and tiger land. ”

Lu Xuan suddenly realized.
