Lei Luo flew with Zhuo Ning for a month, and finally saw a huge black island standing on the sea, which was the famous Black Jade Island in the outer seas.

This island is not much smaller than the four islands of wind, rain, thunder and lightning, and it is thousands of miles long, and there is a rather magnificent city on the island, and the city wall is arranged with a defensive formation.

This island is not well known among ordinary monks, but all the ghost monks know about it, and some even regard it as a holy place.

However, what made Lei Luo speechless was that this island was called Black Jade Island, and it was really black and thorough.

As far as the eye can see, the entire island is pitch black, and the buildings in those towns are also made of a black stone, which looks a little black and shiny.

He estimated that at night, if there was no light curtain warning on the island, even if it was only a dozen miles away, many people might not be able to find the island.

"It's the first time I've come to the Netherworld, and this island is pitch black because it's rich in a stone called black jade, and it can be said that the whole island is made of this stone," Zhuo Ning explained.

Under her explanation, Lei Luo knew the reason.

This black jade is not only exceptionally strong, but it can also exude a force to cover the vitality of the Terran monks, so the ghosts of the Netherworld Sea will not attack here.

Under Zhuo Ning's leadership, the two of them entered the city very easily, and even the entrance fee at the city gate was saved because Lei Luo was a Jindan monk.

"Okay, you lead the way for me, and I'll send you back here, so let's part!" Lei Luo said to Zhuo Ning as soon as he stepped into the city.

All he needed to do was find some accurate information about the Netherworld before he set off, so he wasn't going to take an oil bottle with him.

"In that case, the junior has taken his leave!" Zhuo Ning said respectfully.

After she finished speaking, she walked quickly towards the city, it was obvious that she was lucky to be able to save her life, and what could she ask for.

"Alright, let's go around this Black Jade Island, and find some things for ghost cultivation by the way!" Lei Luo glanced around and planned.

After looking around, he found that there were a lot of ghost monks here, and out of ten people, nine of them were ghost monks, and one person was even a ghost.

The pedestrians on the street where he was standing had more or less practiced some ghost path exercises, and the aura was vague and gloomy, and it was absolutely impossible to admit mistakes.

Even, when Lei Luo was walking, several ghost cultivators who had cultivated in the Jindan stage actually summoned ghosts to accompany him publicly, and all the low-level monks around him avoided them, and no one came to stop them.

However, the appearance of those ghosts is strange, and most of them are the appearance of some demon beasts.

Others were some hideous humanoid ghosts emanating from the slopes, roaring past him, the wind gusting, and the appearance was infiltrating.

"Some ghosts have Jin Dan cultivation, but their spiritual intelligence is so low, and their appearance is not beautiful, they are still exquisitely beautiful!" Lei Luo complained.

He didn't know if the qualifications of those ghosts were good, but in terms of appearance, Lu Linglong could throw them for hundreds of streets.

There is only one town on the entire Black Jade Island, so this city is quite large, and although it is completely dark, there are some surprisingly magnificent buildings in the city.

In the four corners and centers of the city, there is a minaret more than 300 zhang high, these minarets are only fifty or sixty zhang long and wide, but this height is really daunting.

Moreover, the upper part of these minarets is all surrounded by eerie ghosts, and from time to time there are some ghostly ghosts flying from above, flying around the upper end of the minaret, which can be regarded as a characteristic of this place.

By listening to the chats of the residents in the city, I learned that those spires were actually the caves of the Yuan Infant Monks.

In other words, in the entire Black Jade Island, there are actually five Yuan Infant Monks, and they are all Ghost Dao Monks!

Because these were well-known things in the Black Jade Island, Lei Luo quickly learned about the situation of the Yuan Infant Monk on the Black Jade Island.

Not to mention the four around, the most central minaret is the cave of the owner of Black Jade Island.

This person is said to be called the 'Ten Thousand Ghost Ancestor', who has the cultivation of the middle stage of the Yuan Infant, is proficient in the art of refining corpses and controlling ghosts, and is a well-known predecessor in the entire Netherworld.

It is precisely because the ghost monks are in charge of this island that many ghost cultivators dare to release ghost things to 'wander' for a day or two, and some low-level monks or residents in the city are also accustomed to it.

After knowing this, Lei Luo did not hesitate to meditate in his heart, and after a burst of white mist drifted away, a slim girl in white appeared in front of him, it was Lu Linglong.

The monks and residents around were all accustomed to seeing Lu Linglong appear, but some monks were still shocked by Lu Linglong's appearance, and they all looked sideways frequently when they walked.

After all, there are no ghosts or ghosts on my side, and some of the humanoid ghosts are still covered with hair, so they don't look as good as demon beasts.

On the other hand, Lu Linglong's handsome and feminine appearance is more beautiful than that of an ordinary female cultivator, and after comparison, she made a judgment.

"Childe, I feel that the breath here is so comfortable, and there is a place in the distance that seems to attract me to it," Lu Linglong took a deep breath and pointed forward with one hand.

It's no wonder that even spirits and ghosts belong to ghosts, and they are indeed like fish in water and feel comfortable in this ghostly netherworld.

"Alright, let's go find the literature and materials of the Netherworld, and by the way, see if we can find a way to make you advanced," Lei Luo said to Lu Linglong.

After hearing that his son-in-law was going to take her to find an advanced method, Lu Linglong's heart warmed, and she said "um" softly, and then followed behind Lei Luo obediently.

The entire Black Jade Island is very large, and the towns on the island occupy almost half of it, and the entire city is estimated to be eight or nine hundred miles long and wide, so it is quite difficult to find.

Fortunately, Lei Luo knew some experience in the rivers and lakes, and after searching for a long time, he found a three-story shop with the words 'Yin Ghost Pavilion'.

There are people coming and going, and most of them are ghost cultivators, and at first glance it is a relatively well-known shop.

"Welcome seniors to our Yin Ghost Pavilion, I don't know if you want to choose the best ghost things or do you want to buy some ghost path materials?"

This little guy is a fifteen or sixteen-year-old boy, who has cultivated to the seventh level of Qi cultivation, his body is thin, his face is pale, and his aura is a little vague.

Looking at his appearance, he is either in contact with ghosts all year round, or he is also practicing some ghost dao exercises.

"That's enough, I'll receive this senior, you go and entertain the others!"

At this moment, an old man's voice sounded, and the little guy quickly ran away after hearing it and shouting a few words of offense.

"The junior is the shopkeeper of the Yin Ghost Pavilion here, and he has seen the senior!" the person who came was shocked when he saw Lei Luo, and then said respectfully.

This person was a thin old man, with gray hair, a wrinkled face, a gray outfit, and a trace of ghostly aura surrounding his body.

However, this old man's cultivation has reached the late stage of foundation building, and his strength is quite good among the shopkeepers.

The old man was also looking at Lei Luo, their Yin Ghost Pavilion had been open on Black Jade Island for decades, but they hadn't seen the senior in front of them, which meant that the other party had only recently arrived here.

And what he cares about the most is that the ghost thing carried by the other party seems to be quite intelligent, and the breath is even stronger than him, and it seems that he will soon condense the ghost pill and advance to the ghost handsome.

"In that case, there are secluded places, it's too noisy here," Lei Luo nodded.

The old man naturally understood, so he took Lei Luo to a private room on the third floor.

However, the decoration here is really not flattering, and there are actually some decorations of human bones and animal bones, and even the lighting is dark green, which is a local characteristic of Black Jade Island.

"I don't know what the seniors need me to do, our Yin Ghost Pavilion has been open on Black Jade Island for decades, and we have cooperated with several senior ghost hunting teams, and you can find any ghost things or materials you want on our side," the old man said proudly at this time.

Lei Luo was a little interested in the ghost hunter just now, but just by hearing the name, he guessed that it should be a group of monks who went to the Netherworld to hunt ghosts, so he didn't ask too much.

"Since that's the case, then I won't beat around the bush, you can also see that I have just arrived at Black Jade Island, and I have two purposes for this trip, one is to find a way to condense the ghost pill for her, I want as many relevant classics as you have here!"

Lei Luo pointed to Lu Linglong as he spoke, and the old man nodded when he saw it to show that he understood, and he also knew about the cultivation of the other party's ghosts, so there was no surprise.

At the same time, he was quite happy, because the other party was not the kind of senior who was difficult to deal with, and he said the request at once, so he smiled and waited for Lei Luo to say the second purpose.

"Second, I want to know the information about the Soul Heart Stone, you should have it here!" Lei Luo said without hesitation.

As soon as these words came out, the old man's whole face collapsed.

He never expected that the heart of this senior in front of him was so big, and he dared to ask the whereabouts of the soul heart stone, but he couldn't offend the other party when he opened the door to do business.

"In that case, then please wait a while, senior, I'll prepare," After hesitating, he still chose to compromise.

An hour later, Lei Luo walked out of the Yin Demon Pavilion with a solemn face, and at the same time walked towards the black spire in the center of the city.

In the Yin Ghost Pavilion just now, he got many methods about the ghost condensation of ghost pills, as well as some rumors about the soul heart stone.

Now he's walking and studying these things.

Among the methods for Lu Linglong to advance, one of the methods is to devour the soul crystal of the ghost thing, so that Lu Linglong can absorb the essence of the ghost thing in it, and after reaching a certain amount, he can advance.

He also knows a thing or two about this method from other sources, but not all ghosts have soul crystals, generally speaking, the higher the realm of ghost things, the greater the chance of obtaining soul crystals after killing.

There will basically be no soul crystals in the qi cultivation ghost objects, and if the foundation is built into ghost objects, hundreds of them may only obtain a soul crystal, and this kind of soul crystal is far from enough for Lu Linglong to advance in the late stage of foundation building.

The ghost handsome in the Jindan stage is different, basically two or three of them will condense a large piece of soul crystal in their body, and the essence in this high-level soul crystal is enough, basically one piece can make Lu Linglong advance.

However, those classics were not bought in vain, and there was one item that particularly caught Lei Luo's attention, that is, ghosts devoured soul crystals of the same type, so that the success rate of advancement would be greater.

To put it simply, beasts and ghosts want to devour the soul crystals of beasts, and since Lu Linglong is a female ghost, it is best to devour ghosts that are also in the form of women, no matter how bad it is, it must be in the form of a human race.

As for the Soul Heart Stone, there is only one news, and that is that there may be the whereabouts of this thing in the Netherworld Island.

When he was in the Qianji Pavilion on Tianqian Island, he heard the name of this island for the first time, and it was said that a bunch of ghost hunters had seen two ghost kings fighting.

The Soul Heart Stone is the power of reincarnation abandoned in the Ghost King's body, which will only appear after the Ghost King falls, and it needs to be extracted with a special ghost path secret method of sacrifice.

Then the two ghost kings fighting method, if one of them is really destroyed, then the other ghost king may use this secret method to refine the soul heart stone.

The above is the news that Lei Luo got in the Yin Ghost Pavilion, and at the same time, he also asked Lu Linglong to return to the soul card in his body to rest first, and then continue to walk forward.
