Lu Xuan looked at Lian Jiuyou in confusion.

Before he practiced in retreat, he had told him two very important things about refining the Nine Shadows, one was the news of Wucang, and the other was the news of the senior of the Heavenly Machine Gate.

Now that these two things are clueless, what important things are there to disturb his cultivation when refining the Nine Shadows?

Lian Jiuyou hurriedly explained: "Sect Master, I really have no choice, that's why I came to you. In the past year, the predecessors of Yun Zhenyue have successively destroyed many Demon King Cave Mansions and obtained a lot of immortal stones. But recently, there has been a tricky matter, and it urgently needs the sect master to solve it. ”

"What's the matter? Can't even Yun Daoyou solve it?"

Lu Xuan frowned and asked.

Lian Jiu Yu nodded with a wry smile, "It's the gold eater ants who have a problem, and they seem to be starting to be affected by the ghosts......"

Lu Xuan was taken aback.

He was negligent in this matter.

Although the gold devouring ant is weak in demon power, it is also a demon after all, and it will not escape the invasion of ghosts after all.

This is a tricky thing to do.

The number of gold-devouring ants is huge, and Lu Xuan can't set up a white bone city on every gold-devouring ant, right?

Lu Xuan groaned slightly, and then asked, "Where is the Gold Devouring Ant now?"

Lian Jiuyou said: "A few days ago, Senior Yun took the Gold Devouring Ants to build a Demon King Cave Mansion, which is 30,000 miles away from here. Then Senior Yun found that there was something wrong with the Gold Devouring Ants, so he hurriedly controlled them temporarily, and asked Senior Song Yu to come back and send a message and ask the sect master to come forward. ”

"What about Song Daoyou?"

"Now he is waiting outside the temple. ”

Lu Xuan nodded, and Lian Jiuyou walked out of the main hall of the Chiwu Sect.

Song Yu was wandering outside the hall gate, looking a little restless. As soon as he saw Lu Xuan come out, Song Yu breathed a sigh of relief, and greeted him with a wry smile: "Lu Daoyou, you can go with me to take a look, if we can't solve the matter of the gold devouring ants, we are afraid that it will be difficult to grab the immortal stone vein." ”

Lu Xuan nodded and said, "Please ask Song Daoyou to lead the way, let's go and have a look together." ”

Song Yu was even more nervous than Lu Xuan, and without saying a word, he rushed to the sky with Lu Xuan.

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

Under the leadership of Song Yu, Lu Xuan came to the bank of a large river.

The pit on the bank of the river was unfathomable, and Lu Xuan followed Song Yu to the bottom of the pit and saw Yun Zhenyue and others.

Yun Zhenyue was in a hurry, and when he saw that Lu Xuan had finally arrived, he breathed a sigh of relief.

"Lu Daoyou came just in time, let's go and see the gold devouring ants. Yun Zhenyue took Lu Xuan to the depths of the mine, and saw that the dense gold devouring ants were all gathered together, looking restless. Some of the Gold Eaters attacked each other, roaring in bursts of noise. And on top of a pile of fairy stones, the queen of the gold-devouring ants prostrated there, motionless, turning a blind eye to the riots of the gold-eater ants.

With a wave of his hand, Lu Xuan stuffed all the Gold Devouring Ants and Gold Devouring Ant Queens into the Xiyang Furnace.

Yun Zhenyue blinked and asked, "Is this the end?"

Lu Xuan smiled bitterly: "There are too many gold devouring ants, I'm afraid it will be difficult for me to help them solve the problem one by one." I'm afraid that our mining of the fairy stone veins will come to an end for the time being. These Gold Eaters are only protected from the ghosts in the Furnace, and after a while, they should settle down. ”

Yun Zhenyue and the others looked at each other, so they had to nod helplessly.

"So what do we do from here?"

Yun Zhenyue asked regretfully.

The five of their senior brothers have had a very leisurely year this year, and with their cultivation, it is difficult for any demon to resist. They can not only slay demons and demons, but also dig up a large number of immortal stones, whether it is the Chiwu Sect, the Dao Mountain, or the Jinwu Clan, they have all benefited a lot. Now that there are no gold devouring ants, they are suddenly idle, and several human emperors are a little uncomfortable.

Lu Xuan smiled and said: "Several Daoists have also worked hard for a year, you might as well go back to Daoshan Mountain to rest for a while, and when I come up with a solution to the problem of gold devouring ants, it is not too late to continue." ”

Yun Zhenyue and the others had no choice but to nod, and after saying goodbye to Lu Xuan, they flew in the direction of Dao Mountain.

Lu Xuan didn't stop, and according to the direction given by the previous refining of the Nine Shadows, he went to another Demon King Cave Mansion and found the Jinwu people led by Wu Lei.

During this time, Yun Zhenyue and Wu Lei divided their troops and swept through the Demon King Cave Mansion, and they also had a large number of gold devouring ants in Wu Lei's hands, and those gold devouring ants should have the same problem.

Sure enough, as Lu Xuan expected, when he arrived, Ou Lei was also helpless against the crazy gold-devouring ants.

After Lu Xuan took back all the gold-devouring ants, he took Ulei and the Chiwu people back to the Mountain of No Return.

Now that there is no shortage of immortal stones in either Chiwu Sect or Daoist Mountain, at least for three or two years, there is no need to attack the Demon King Cave Mansion everywhere. Lu Xuan asked Wu Lei to take the Golden Crow people to rest temporarily, while he entered the Xiyang furnace and looked at those gold devouring ants in a daze.

He first set up a city of bones in the head of the queen of gold eaters, and when the queen of gold eaters stabilized, he could control those gold eaters ants.

But what about the tens of thousands of gold-eating ants besides the queen of gold-eating ants?

Although it was easy for Lu Xuan to set up the White Bone City, if he set up tens of thousands of White Bone City, he would need too many divine souls, and he would not have any way.

Lu Xuan and the Queen of the Gold Devouring Ants stared at each other for a long time, and finally could only sigh and give up.

Let the Gold Eater Ants recover in the Furnace of Resting Soil, they will no longer be infested by ghosts in the secret realm, and it should not take long to recover their original state.

This is Lu Xuan's only choice.

However, Lu Xuan didn't let the Gold Devouring Ants sit idle, and there were still many ruins of Anode City piled up in the Soil Furnace, so he let the Gold Devouring Ants continue to refine the Taiyi Gold Essence, while Lu Xuan was ready to continue practicing.

A moment later, Lu Xuan returned to Linglong Mountain.

During this time, he had been practicing at the foot of Linglong Mountain, where there was still a new house for him and his little sister, and everything was the same as before.

The reason why Lu Xuan wants to practice here is to remind himself at all times that the little senior sister is still missing, and he can't slack off in the slightest.

He walked straight to Xuanhu Lake and saw a little mouse that had just finished his cultivation and was stretching his muscles.

At this time, the cultivation of the gray slave has also entered the realm, and the blood and qi around him are clouded, and he is already a little demon who has become quite a climate.

Seeing Lu Xuan come back, the gray slave squeaked excitedly, as if he was showing off his growth.

Lu Xuan was suddenly stunned, and looked at the gray slave blankly for a long time.

The gray slave was a little inexplicable, and thought that something was wrong with him, but the probe looked at it for a long time through the reflection of the lake water, and it didn't seem to be anything unusual.

Lu Xuan suddenly appeared beside the gray slave and picked him up.

"What the hell is going on with you little one?"

Lu Xuan stared at the gray slave with bright eyes and asked, but the gray slave couldn't speak, so he could only look at Lu Xuan a little timidly, not knowing what was wrong.

At this time, Lu Xuan grabbed the gray slave, and his mind echoed the words that Yun Xuanyue said when he first saw the gray slave.

At that time, Yun Zhenyue asked Lu Xuan very strangely, why was the gray slave not affected by the ghost?

At that time, Lu Xuan didn't care, but now he suddenly remembered this, and his heart was suddenly full of questions.

yes, why is the gray slave so fine?

Even the gold-devouring ants that have just arrived in the world of the young prison are inevitably affected by the ghosts, and the gray slaves are native young labor demons, how can they be safe and sound all the time?

Could it be that the Grey Slaves are immune to ghosts?

Lu Xuan took a serious look at the gray slave for the first time, but on the surface, he couldn't see anything unusual at all.

"I'll go to your head and don't be nervous. ”

Lu Xuan comforted the gray slave, and a wisp of spirit entered the gray slave's mind.

At this moment, Lu Xuan suddenly shook all over his body!

There was indeed no ghost in the gray slave's mind, but there was something completely unexpected by Lu Xuan.

That...... It's a magic circle!

Familiar runes, familiar structures, familiar breaths, Lu Xuan could confirm almost immediately, this was a Heavenly Machine Gate magic circle!

Although this magic circle was layered and there were many runes, it was composed of the simplest spirit runes.

Even if the formation of the magic circle is the most basic spirit rune, even Lu Xuan can't help but admire the ingenuity of this formation, which has the wonder of returning to the basics.

He couldn't help but look up to the sky and howl excitedly.

In the past two years, he has worked hard to find clues about the predecessor of Tianjimen, but he has found nothing. Who knew that what he was looking for was always by his side.

It's really hard to find a place to break through the iron shoes, and it takes no effort to get it.

Lu Xuan excitedly left the gray slave's mind, trying to ask the gray slave if his master was the senior of the Tianji Gate.

But to Lu Xuan's surprise, the gray slave didn't know anything about it, and he didn't know what Lu Xuan meant.

The gray slave obviously didn't lie, but Lu Xuan was a little confused.

If the gray slave had no relationship with the senior of the Heavenly Machine Gate, why did that senior bother to set up such a subtle array in his mind?

Could it be the handiwork of the disciple of that senior?

Lu Xuan shook his head and denied his idea.

That formation is very ingenious, and it is definitely only possible for a medium and high master to do it. Even though Lu Xuan had been immersed in this Tao for several years, it was difficult for him to understand the mystery. Moreover, the gray slave was just a small demon who did not enter the stream before, and being able to set up a huge magic circle in his mind was tantamount to carving a 10,000-word article on millet rice. There is a great possibility that such a handwriting was imprinted by the predecessor of the Tianji Sect himself.

Lu Xuan failed to get a clue from the gray slave, so he entered his mind again.

Although this magic circle is wonderful, Lu Xuan has a red rope of Xuan runes, and even if the magic circle composed of this kind of spirit rune is ten times more complicated, it can't hide from his magic eyes.

After a long time, Lu Xuan finally opened his eyes, revealing a relieved expression.

He finally figured out the truth.

That formation has three effects.

First, urge the gray slave to look around for the fairy stone vein, and then memorize the location of the vein in his mind.

Second, to erase a certain memory of the gray slave, Lu Xuan judged that what was erased by the magic circle should be the entire process of the Tianjimen predecessor setting up the formation in the gray slave's mind.

The third, and what made Lu Xuan's heart flutter the most, was that every ten years, the magic circle would trigger itself and forcibly prompt the gray slaves to rush somewhere.

And the location of that place has now been mastered by Lu Xuan.

Lu Xuan almost dared to conclude that the predecessor of the Heavenly Machine Gate was hiding in that place!
