Within the Ghost City, there were three levels. The outer layer was where the low cultivation wandering soul s resided; the middle layer was where the powerful Ghost King s lived; and the middle layer was where the Ghost King Liu Wu's palaces were located.

It was just because Ghost Emperor had used his great powers to cultivate underground, from the outside, it looked similar to the outermost layer of buildings.

As the Ghost Emperor's cultivation was much higher than Lin Jin's, he was not confident that he could avoid being discovered by the Ghost Emperor either. With a flash of inspiration, he used the latent nerve to hide his own presence, and then transformed his own aura into that of a little imp.

This kind of exquisite control over the aura was also thanks to the principle of Zhou Ji controlling the aura three years ago. Although it was a little biased against the real "dao", it also allowed Lin Jin's control over his own body and aura to reach an extremely high realm on the way of cultivation.

Carefully avoiding the ghosts, he slowly walked towards the center of Ghost City. Seeing that he was already far away from the ghosts, Lin Jin suddenly thought of something.

The deeper he went into the Ghost City, the more he realized that this Ghost Emperor was not simple. Every building here, was arranged according to the formation pattern of the Three Yin Circulation Diagram, and when combined together, they formed a Nine Rhythm Yin Convergence Array, continuously pulling out yin qi from all four directions of space and underground. Furthermore, the yin qi he absorbed also maintained the shape of the entire Ghost City, for the use of the Ghost Cultivators in the city, they were truly extraordinary.

When he arrived at the center of Ghost City, he realized that the center of the Ghost City was a square with a perimeter of more than a hundred meters. Under the encirclement of the four buildings, Lin Jin was surprised to find that at the center of the square, there was a huge jade-like stone wall.

It was five Zhang wide, and at the top of it, there was a rock that looked like a wolf crescent moon. The black gas around it floated, and it looked extremely eerie.

Lin Jin observed that at the mouth of the Sky Wolf's mouth, the yin qi were evidently more concentrated than at other places. Furthermore, they were constantly communicating with the auras of the outside world. This place was the entrance to the Ghost Emperor's residence.

However, as a precaution, he did not rashly barge in. Instead, he hid in a corner and waited.

After about ten minutes, two balls of black gas appeared in the air and flew straight into the wolf's mouth.

Lin Jin could feel that the two black gas s were indeed the Ghost Generals' Qi fluctuations. Not daring to hesitate, he immediately shrunk his body and flew towards the wolf's mouth.

As soon as he entered. Lin Jin felt as if he had entered another space as he suddenly opened his eyes. Below him, there was a huge palace standing upright, and its magnificence was not inferior to that of the Forbidden City.

It seems that this Liu Wu also paid attention to enjoyment after death!

However, it was different from the palaces in the mortal world. There was a huge pagoda within the palace, and it was quite a bit taller than the palaces.

At the top of the tower hung a black metal signboard with the words "Tower of Souls" written on it. It was the Ghost Emperor's usual place of cultivation.

From afar, he could see the ghost aura surrounding the tower and the billowing demonic clouds. Every quarter of an hour, tens of thousands of tragic green light lights would emit from the bottom of the tower, giving off a sense of majesty from this creepy place.

Come to think of it, the Ghost Emperor and the Grand Cloud Immortal Pavilion that Lin Jin had obtained were in different dimensions.

However, although the Ghost Emperor had trained for a few thousand years, without the support of his physical body, he could only absorb and use yin qi s. His abilities were much worse than the Grand Cloud Immortal Pavilion's master's, so the tower was naturally much weaker as well.

Their might was sufficient, but it was not enough. Even though it had been perfected for more than a thousand years, it was still difficult for him to gather those yin qi in one place. Not at all.

The tower was divided into three levels. The highest level was for himself, and the second level was for the s that he trusted. The lowest level was where the Ghost Emperor had imprisoned his opponents for all these years. And underneath this tower, was the other ghosts of the Profound Ice Prison that were in fear.

Although the Mountain Spirit King that caught Feng Wanshan had cultivated for a thousand years, he didn't have any good cultivation methods or venues, only the cultivation of an ordinary soul. At most, it would be condensed into a spirit body and wouldn't have much ability, so the Ghost Emperor let go of the two ghost generals to capture him.

"Report ~" Just as the two Ghost Generals brought Mountain Spirit King into the Ice Prison, they walked towards the tower.

"Come in!" Ghost Emperor's powerful voice came from far away into the palace. Two ghost generals lowered their heads and steadily brought Feng Wanshan's spirit stone into the palace on a white tray.

"Reporting to the Ancestor, the Mountain Spirit King has already been thrown into the Profound Ice Prison. This is Feng Wanshan's spirit stone, I hope the Ancestor can instruct me!"

"Hm!" You can all leave first! " Ghost Emperor looked at the soul stone and nodded in agreement. The two Ghost Generals did not dare to say more, and carefully retreated with a bow.

Seeing that they had retreated out of the tower, Liu Wu waved his big sleeve, causing a green light to hit Feng Wanshan's soul stone.

The green light on the green stone grew larger, and after the light faded, Feng Wanshan's figure appeared, his pale white face became even more tired, his originally straight body had become hunched, and the light in his eyes had disappeared.

"You are Feng Wanshan?" Ghost King Liu Wu sat steadily on his precious wooden chair, and said to Feng Wanshan.

Although Feng Wanshan had paid respects to the Ghost Emperor with the other Ghost King hundreds of years ago, that had already been many years ago. Now that he had also been imprisoned by the Mountain Spirit King for a few more years, how could he still remember Liu Wu's appearance?

It was not the Mountain Spirit King that had released him, but a powerful thought that he could not resist.

Could it be that another even more powerful Ghost King found out and captured him? Feng Wanshan was perturbed, he looked at him, then at the ground, not daring to look.

At this time, Liu Wu's voice sounded again, "You are Feng Wanshan?" There was impatience in his tone.

Hearing this voice, Feng Wanshan felt goosebumps all over his body. He had no choice but to raise his head again and look at Liu Wu, who was sitting on the majestic yin qi's throne. Feng Wanshan subconsciously wiped his eyes and asked suspiciously: "May I ask who you are …?"

Because he had a lot to do with the matter regarding the Holy Spirit, Liu Wu thought that maybe there would still be a use for him, so he did not act too coldly. He waved his hand and said, "This empress is the Ghost King Liu Wu!"

"AHH!" So it was the Ancestor! That little brat is Feng Wanshan! When Feng Wanshan heard the Ghost Emperor's registration number, the image of the Ghost Emperor from a hundred years ago appeared in the depths of his soul. It was indeed the same as the man he saw before.

"En!" Liu Wu nodded slightly, and said without a care: "That Mountain Spirit King, has already been imprisoned by this emperor in the Profound Ice Prison. Liu Wu walked down from the throne and extended his hand to help Feng Wanshan up.

Seeing him using the dignity of the Ghost Emperor to help him up, Feng Wanshan's initial worries disappeared without a trace, as if they had been washed by the spring wind. He felt even more moved in his heart.

"This little ghost is just an ordinary ghost. To be able to receive such a great favor from the Ancestor, this little ghost will never be able to repay the favor."

"Hehe, no need to be like this. You are the ghost that belongs to my land, and even if I were to take care of you, you will still suffer for three years. However, this Emperor's land is not good enough for me." Hearing him say that, Liu Wu's smile became even more intimate.

Although there were many secrets of the soul that he did not know, he was already familiar with the control over the emotions of the ghosts. In a short while, Ghost Emperor dispelled the worry in his heart, and they were as close as a family.

At this time, outside the Tower of Souls, a ball of black mist was quietly floating there, without a sound, as if it had merged into the tower. Even the ghost aura outside the tower passed through the ball of black mist without any hindrance.

At this time, after being bewitched by the Ghost Emperor, Feng Wanshan had almost treated the Ghost Emperor as his most respected and trusted person. After hesitating for a long time, he couldn't help but say, "Ancestor, this little one has a request, I hope that the Ancestor can agree to it."

"What is it?" Ghost Emperor's heart was moved, but he did not reveal it as he replied.

"The little ghost has a granddaughter who was sent away by the little ghost a few years ago and has yet to find his whereabouts. Right now, the little devil's soul is incomplete and is hard to find. I hope the Ancestor can help me find her."

"This is a small matter. Tell me where your granddaughter is hiding and I will help you find her!"

"Many thanks, Ancestor. My little granddaughter's name is Yin Yin. She should be here …"

When Feng Wanshan just finished speaking, the black mist outside the tower suddenly trembled, and transformed into an light smoke, flashing into the hall at an extremely fast speed. Ghost Emperor was surprised seeing this, and immediately reached out to stop him, but who knew that the black mist actually passed through his hand, straight towards Feng Wanshan.

Feng Wanshan did not expect that there would be someone who would dare act so impudently in the Ghost Emperor's residence, he could not help but be shocked, and before he could even regain his senses, a sparkling spiritual energy fighter suddenly appeared from the black mist, grabbing him into the black mist and disappearing.

The black fog suddenly accelerated and rushed out of the tower. However, just as it was about to come in contact with the wall, a layer of ripples appeared and bounced the black fog back.

"It's you again! This emperor had already expected that you would still be here, but I didn't expect you to be so bold as to actually dare to trespass into my Tower of Souls. Come!" The calm face of the Ghost Emperor suddenly became sinister. A black light flashed in his hand and his figure appeared outside the tower, but the tower had shrunk to a size of a foot and in his hands, a pitch black hole had appeared in the bottom of the tower. The hole was so deep that the bottom couldn't be seen and it was filled with churning black flame s.
