"Well, there you have it!"

With the browsing of the memories of the fire jade, Cheng Bo finally found the immortal-level exercise he wanted.

This exercise is called "Reincarnation Dream Sutra", through the practice to create dreams, in the dream world to continue to experience reincarnation, so as to constantly temper and improve one's spiritual power.

It's a pity that the level of this exercise is not high, and it is not complete.

Only the first half, after cultivation, at most reach the peak of the Immortal One.

But Cheng Bo still decided to cultivate.

Because the enemies he has to face are very strong, and he can only cope with the enemies that come after him if he continues to improve.

However, before he could practice this exercise, he still had to increase the amount of his spiritual power.

I've explained it before.

The Devouring Demon Worm with devouring supernatural powers has its own spiritual power hundreds or even thousands of times that of cultivators of the same level.

Although Cheng Bo couldn't make the amount of his spiritual power reach that level by devouring the supernatural power, there was still that possibility, dozens or hundreds of times.

But he didn't plan to learn to devour the souls of others indiscriminately like devouring demon insects, Cheng Bo planned to devour the souls of the wicked.

With a thought, he summoned the system interface.

A finger clicked on the "Summon" button.

Suddenly, the window of the world appeared.

In the picture is a dark world, where the creatures are actually floating.

"Ghosts?"

Soon, a ghost was summoned.

After some exchanges, Cheng Bo learned some information about this world, this world is called the Nine Nether Realm, and all living beings in this world exist in a soul state.

They will devour each other.

It's really sleepy, and someone will send a pillow.

After sending the ghost away, a smile appeared on the corner of Cheng Bo's mouth.

Suddenly, his heart moved, this can't be arranged according to the plan, right?

"You're not stupid!"

Yiyi's voice sounded in his head.

"Yiyi, you are so good to me!"

Cheng Bo was moved.

"Don't talk nonsense, hurry over!"

Tang Xinyu urged.

So, Cheng Bo consumed two money treasures and traveled into this world.

It was dim, gloomy and cold, and Devil May Cry kept coming from all around, this was how this world gave Cheng Bo, and he also found that he exuded a bright light all over his body, just like the sun in the dark.

"What a thick yang energy!"

"Swallow him!"

"Tsk, food!"

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

As soon as Cheng Bo appeared, he was targeted by countless ghosts, and then they all showed hideous faces and rushed towards him, for fear that one step at night would become food for other ghosts.

"Good time!"

Cheng Bo snorted lightly and turned on the Devouring Divine Power.

The next moment, his body skyrocketed dozens of times, turning into a giant of nearly 100 meters, opening his mouth and sucking in, all the ghosts that rushed towards him were sucked into his mouth.

Without refining it himself, the Devouring Rune bloomed brightly, and within half an hour, these ghosts were refined into the purest spiritual power, and integrated into Cheng Bo's spiritual power.

It made his mental power increase by about one percent.

This disappointed him, devouring hundreds of ghosts at once, only to increase by one percent.

It seems that we will have to find some high-level ghosts to devour.

These lonely ghosts are not stupid, they swallowed hundreds of ghosts in an instant when they saw Cheng Bo, and they fled quickly in all directions.

"Come here for me!"

Cheng Bo drank lightly, grabbed it with his probe, and suddenly, the ghosts within a radius of 100 miles were captured by him, and the number reached 10,000.

The big mouth opened, and the ghosts rushed into him involuntarily.

Half an hour later, a large amount of black mist emerged from Cheng Bo's body, these were all impurities contained in the body of the lonely soul and wild ghost, and what he needed was the purest spiritual power.

After swallowing more than 10,000 lonely souls and wild ghosts, Cheng Bo's spiritual power increased by more than thirty percent on the original basis.

Cheng Bo is still quite satisfied with this.

The next moment, Cheng Bo's body returned to its original state and shot away in one direction at will.

Half an hour later.

"What a lot of yang energy!"

"Swallow him!"

"Oh, no, this person wants to eat ghosts!"

"Run!"

When the ghosts cried and the wolves howled, one by one the ghosts were incorporated into Cheng Bo's body and quickly refined.

An hour later.

Cheng Bo showed an extremely satisfied smile on his face, his spiritual power had doubled, and the Devouring Divine Soul in his soul would exude a special power, which made his soul accommodate a lot.

"Ghost town!"

Suddenly, Cheng Bo's eyes froze, but on the ground in front of him, a huge ghost town appeared.

In front of the city gate, there is a three-meter-tall, hideous and terrifying appearance, holding a ghost fork as a guard.

The next moment, Cheng Bo controlled his spiritual power to sweep towards the ghost city, but found that there was actually a layer of enchantment on the city to stop his spiritual power.

"Someone from the sun!"

The team of fierce ghosts guarding the city discovered Cheng Bo, but they didn't want to eat him like those lonely ghosts, but they were a little more vigilant on their faces.

Cheng Bo discarded the memories of those ghosts, otherwise, just so many memories would be enough to impact him into delirium and become a psychopath.

The next moment.

Cheng Bo made a move.

The detective grabbed it, and all the eight ghosts guarding the city were captured by him, and then, the devouring magic power unfolded, swallowed them, and retained a memory.

The ruler of this ghost city is called Dongyin King, and he has three ghost commanders, thirty-six ghost generals, and 100,000 ghost soldiers who have reached the level of powerful ghosts.

According to Cheng Bo's analysis.

The Ghost King is also on par with the strength of an out-of-body cultivator, so there is nothing to be feared.

So, he broke into this ghost town directly.

He was too conspicuous to hide, and as soon as he entered the city, he was discovered by the patrolling ghost soldiers.

"Yang Shilai!"

"Catch him!

"Quick, don't let him run!"

In a moment, Cheng Bo was surrounded by thousands of ghost soldiers, led by a ghost general.

"It's so rich, if you cook it and eat it, it will definitely be delicious, but unfortunately, there are too few yang people who have broken into this world, and there are very few people like you who have such a strong yang energy, so I can only sacrifice you to the king to deal with!"

Hearing the words of the ghost general, Cheng Bo was not annoyed.

The next moment, he reached out and slapped it.

"Boom!"

The huge palm print formed in the void and fell, and in a breath, the ghost general was all smashed to pieces.

Then, Cheng Bo unfolded the Devouring Divine Power and inhaled the soul power in the air into his body.

"It's doubled!"

The soul quality of a ghost general and thousands of ghost soldiers was very high, which doubled Cheng Bo's spiritual power.

"Who, who is presumptuous on the king's territory!"

With a loud shout, a huge ghost creature more than twenty meters tall, wearing soul armor and holding a soul soldier appeared.

The ghost's gaze fell on Cheng Bo's body, and a green light couldn't help but emerge from his huge eyes like copper bells, obediently, the yang energy on this kid's body is so rich, if he swallows him, the strength of this king will definitely be able to go to the next level.

"Kill!"

Thinking of this, the ghost king pressed the suffocation and waved the soul soldier towards Cheng Bo.

"Dang!"

Cheng Bo flicked his fingers, and a strong force hit the soul soldier, and the ghost king directly took the soul soldier and flew out.

"This kid from the sun is so strong!"

The ghost king was frightened, turned around and ran.

"Where to go!"

Cheng Bo drank lightly, and the huge spiritual power radiated, imprisoning the ghost king in an instant.

In an instant, the devouring divine power unfolded, swallowing the ghost king.

At the same time, he also browsed the memories of this ghost king.

Immediately, after learning about the memory of the ghost king, Cheng Bo's brows couldn't help frowning slightly, this world doesn't seem to be the real underworld, because in this world, there is no so-called underworld.

The ghosts of this world all appear here suddenly, but they only have sporadic memories and do not remember all kinds of past lives.

And there is no such thing as reincarnation in this world.

Only by reaching the level of ghosts and immortals can you break the confinement of this world and go to another world.

Also, this Dongyin Ghost King is only one of the weakest of the many ghost kings, and this place belongs to the edge of the Nine Nether Realm.

After a short period of digestion, Cheng Bo was in this city, killing on a large scale.

When he slaughtered and absorbed the ghosts in this city, his soul was ten times stronger than when he first entered this world.

But it was far from reaching the limit of devouring runes.

In the next few days, Cheng Bo slaughtered seven cities in the Nine Nether Realm, because he would not let go of any ghost, so the news had not yet spread, but his spiritual power was a hundred times stronger on the original basis.
