Just when Xia Yin was excited in his heart, the voice of the ghost lord came again.

"Xia Yin, come to this seat!"

Xia Yin naturally didn't dare to slack off, walked over quickly, and bowed down to listen.

"What did you sense from this tower?" asked the ghost lord calmly.

"The younger generation sensed that this giant tower was like a sleeping ancient beast, with a faint and powerful aura, and it was very spiritual, not inferior to human wisdom at all!"

"What else?" asked the Ghost Lord again.

"There is also the Heaven and Earth Yuan Force and Spiritual Qi that escape from the tower, which are more refined than the spiritual energy of the younger generation anywhere in the human world, which is like ...... The difference between a human Qi refining rookie and a Yuan Infant Cultivator!"

The ghost lord nodded in satisfaction.

"Well, it is worthy of the elite of our race who grew up in the human world, your induction is very accurate, this tower is an innate treasure, which is divided into eighteen layers, each layer is an independent world, and the aura in this valley is actually another more advanced spirit of heaven and earth, named ......"

After a pause, the ghost lord immediately waved his hand and wrote a word in the air.

The next moment, a clear word "Qi" appeared in the air.

This random display of magical powers shocked Xia Yin's heart, this method is similar to drawing soul talismans directly in the air!

"Innate Treasure, there are eighteen independent worlds in it......"

The words of the ghost lord were far beyond the scope of Xia Yin's cognition.

According to Xia Yin's cognition, above the magic weapon is the spiritual weapon, and what is more advanced than the spiritual weapon is the magic weapon, and above the magic weapon, is the spiritual treasure.

As for whether there are more advanced treasures on top of the spirit treasure, Xia Yin doesn't know, let alone what the name is.

Innate treasure, this is the name Xia Yin heard for the first time.

"Senior, what is an innate treasure?"

Xia Yin asked expectantly.

The ghost lord said: "Above the magic treasure, is the spirit treasure, the spirit treasure is divided into the acquired spirit treasure and the innate spirit treasure, the acquired spirit treasure is the treasure refined by the ancient power, and the innate spirit treasure is the treasure automatically derived from heaven and earth, containing some or even several laws, above the innate spirit treasure, it is the innate treasure, and it is also the treasure derived from heaven and earth, containing the avenue. ”

An explanation made Xia Yin completely stunned!

"It turns out that there are so many treasures on top of the magic weapon!"

I originally thought that the magic weapon already belonged to the most powerful treasure in the immortal cultivation world, and as for the spirit treasure, it was already a legendary thing, and it could not appear in today's world at all......

But I never expected that in this Netherworld Holy Land, there was an innate treasure!

I don't know what kind of power this treasure has?

As soon as this question arose, Xia Yin instantly understood that this was not something that his realm could understand, so he couldn't help but ask it, but asked another question.

"Senior, what is this Qi?"

The ghost lord had already expected Xia Yin to ask this question, and explained for Xia Yin with a smile:

In ancient times, the heavens and the earth were filled with almost endless qi, which was as indispensable for monks as the aura of the human world today.

It's just that Qi is much more advanced than aura, similar to the difference between lower-grade spirit stones and top-grade spirit stones, the reason why there are all kinds of huge beasts like mountains in the ancient world, giant spirits, is because they absorb Qi, almost no need to cultivate, and the change can stimulate the bloodline inheritance talent in the body, and they have strong strength!

At that time, the human cultivators were called Qi Refiners, because of the existence of Qi, the cultivation speed of these Qi Refiners was also very amazing, and within a few decades, they could cultivate to a strength comparable to the current God Transformation level......

It's a world of all sorts.

However, in a catastrophe, whether it was a powerful giant spirit beast, a demon race, or a human qi refiner, they all suffered a devastating blow and were annihilated ever since.

The Qi that originally filled the entire ancient world was also consumed and depleted in the catastrophe......

After the disaster, the world gradually regained its vitality, but it was no longer as prosperous as it used to be, and the restored world could only derive heaven and earth aura that was countless times lower than Qi, and the cultivation speed of humans and other races became extremely slow and difficult......

When the ghost lord stopped, Xia Yin couldn't help but ask: "Senior, what kind of catastrophe happened in the ancient period that completely changed the whole world!"

A mysterious smile appeared on the ghost lord's face: "Do you want to know?"

Xia Yin nodded.

"Hehe, then you have to become the tenth disciple of the old man, that is, the last disciple of the closed door, to be qualified to know some ancient secrets, if you want to know them all, you have to be the candidate for the next ghost master!"

"This ...... Ahem, the juniors are just curious!"

Xia Yin hurriedly refused.

"Don't be in a hurry to make a decision, this seat said, it will never be difficult for others, and it will not restrict any freedom of action for you, and if you want to worship this seat as a teacher one day, you have to accept the test, and you can only do it after passing it successfully!"

Xia Yin couldn't help but secretly slander in his heart: "It's still a test, I wish I could leave this ghost place as soon as possible!"

However, this can only be thought about in his heart, Xia Yin didn't dare to show it on his face, and asked pretending to be interested: "Test, please make it clear to the seniors, what test do you need to pass?"

"Haha...... But it doesn't matter if you want to know or not, because I won't tell you if you go first, and only the day you decide to bow down to my door will you know what kind of test you will pass!"

Xia Yin could only smile bitterly and nodded, not daring to ask.

The old monster at the level of the god seems to be able to see through people's minds, and these small abacus in his heart can't escape the eyes of the ghost lord at all.

The ghost lord glanced at Xia Yin, then looked at the tower in the distance, and his face instantly became serious.

"In this town tower, there are many secrets of the ancient world, even the ghost masters of the past generations like the old man only know the tip of the iceberg!"

At this time, Luo Changhan on the side couldn't help but ask: "Phantom Lord, my subordinates have overheard that after choosing the next heir, the Phantom Lord of the past generations will enter the world above the tenth layer of the Town Tower, and will never come out again, I don't know ......."

The ghost lord nodded slightly: "That's true, after the ghost lord of the past dynasties is approaching the great limit or after cultivating to the realm of the Great Perfection of the Transformation God, he can no longer make the slightest breakthrough in this world, and he will enter the world above the tenth floor of the Zhenyu Tower, as for whether they will sit in the Zhenyu Tower, or have another breakthrough, this seat is unknown!"

Xia Yin's heart instantly had another question.

"Senior, since the ghost masters of the past generations have entered the world above the tenth floor of the Town Tower, what about the world below the tenth floor?"

The ghost lord glanced at Xia Yin meaningfully: "Want to know?"

"Ahem...... The juniors are just, just curious!"

Xia Yin quickly shut up and didn't dare to ask again.

The ghost lord was obviously not ready to answer this question, but changed his words: "Okay, there are some things that you can't know now, what the old man wants to tell you is that in fact, most of the people in my Netherworld are also humans, even if they return to the human world one day, they will not cause any devastating harm to the creatures of the human world, don't be misled by those ignorant guys outside!"

Xia Yin bowed his head and was silent.

However, deep down, he didn't think much of the words of the ghost lord.

At the beginning, in the southern part of the Chaotic Star Domain, he saw with his own eyes that the demons of the Netherworld were preparing to use some kind of formation to demonize the mortals in the entire city.

Turning people into something else that is not human and not ghost, isn't this destruction?

Xia Yin began to be a little suspicious of the words of the ghost master......

At this moment, the sound of buzzing and shaking suddenly sounded.

The ghost lord took out the transmitter from the storage ring and glanced at it, and his face instantly became solemn.

"Senior, what's going on?"

Xia Yin asked.

"The person who was planted in the Demon God Temple reported that in the Netherworld Death Land, there may be hidden altars that have not been destroyed!"

Xia Yin was a little unconvinced: "It's impossible, so the altars were all destroyed by the juniors themselves! And in that mountain range, the juniors used their spiritual power to investigate countless times, but they didn't find other altars!"

The ghost lord shook his head: "If it is the hidden formation arranged by the demon lord and this seat himself, unless the spiritual power is more than twice as strong as the two of us, it is possible for the monk to find out, this seat suspects that in that mountain range, there are more important things than the hundreds of altars you destroyed, so the demon lord left hundreds of Yuan Infant monks without a trace to secretly protect them during the retreat!"

The ghost lord looked at Luo Changhan and the other old monsters: "Elder Luo, this seat orders you to select five hundred Yuanying monks and go to the Netherworld Death Place to investigate, remember, if it is not necessary, don't fight with the monks of the Demon God Temple, just send the news back!"

Luo Changhan nodded respectfully.

"Remember, the old man is going to accept Xia Yin as an apprentice, and he can't spread it, go ahead!"

A group of primordial old monsters flew up one after another, shooting towards the outside of the valley......

The ghost lord glanced at Shen Lang and the other demon disciples: "You guys should go back too!"

After dozens of demonic disciples bowed and saluted, they also flew away.

Xia Yin looked at the ghost lord with some nervousness: "If the seniors have nothing else, the juniors will also ......."

"Don't go yet!"

The ghost lord shook his head and stopped Xia Yin.

Xia Yin's heart couldn't help but tighten, and his heart became even more nervous.

"Do you still have orders from your predecessors?"

The Ghost Lord didn't speak, but kept staring deeply at the tower in front of him......

After a long time, the ghost lord turned around and looked at Xia Yin: "The plane passage to the Chaotic Star Domain, in addition to my Netherworld Hall monks, there are also people from the Great Wilderness Valley and the Demon God Temple, unless this seat personally sends you there, those people will let you go, but this seat has an extremely important matter, and you can't get out of it for the time being, you can only stay in this valley for a while, and then send you away when this seat finishes things!"

The ghost lord's words, Xia Yin was a little skeptical.

However, in the face of a god-level old monster, Xia Yin knew that he was not qualified to bargain, so he could only reluctantly nod.

The ghost lord obviously saw Xia Yin's inner apprehension, and couldn't help but laugh.

"You don't need to be suspicious, as the head of the Netherworld Temple, this seat will not lie to a junior, and you also know something about the important thing that this seat said, which is to go to the Blood River Sect and restore the seal destroyed by the Shura Clan!"
