There was once a very domineering powerhouse in the Ghost Domain, that was the Hell Fire Refining Emperor, its origin was very mysterious, and even the ghosts in the Ghost Domain didn't know where its roots were.

The prestige of the Hell Refining Fire Emperor was extremely high, and the Nine Hells created by him single-handedly terrified all the ghosts.

The so-called Nine Prisons are actually similar to the Nine Cities founded by the Ghost Emperor Yan, and they are also the nine great cities built around the core area of the Ghost Domain.

When Xiao Ning, Ling Xianxian, Chu Feifeng, and Qin Hongling hid in the Heavenly Machine Tower, the Nine Prisons created by the Hell Refining Emperor reappeared.

The first prison of the Nine Prisons is the Black Water Prison, which has a black water pool, and once the ghosts are taken into the Black Water Prison, they will be eroded by the black water day and night, and they will be miserable.

The second hell is Purgatory, and there is a platform for purgatory, and the ghosts who are taken into it have to suffer day and night from the fire.

The third prison is the Knife Mountain Prison, and there is a knife mountain in it, and ghosts enter it and are touched to the knife mountain. Although the ghost thing has no substance, entering this sword mountain is as if it has become a physical object, and it bears a huge pain of cutting.

The fourth prison is the Thunder Sea Prison, there is a sea of yin and thunder in this prison, and the ghosts who enter the Thunder Sea Prison must always suffer from lightning strikes, you must know that thunder has a strong restraint effect on ghosts, so the ghosts here are more painful.

The fifth prison is the oil boiling prison, and this prison has a huge oil boiling pool, and the hot oil juice constantly baptizes the ghosts, making the ghosts miserable.

The sixth hell is the Five Cracks, where the ghosts will be torn apart and will also suffer great pain.

The seventh hell is the Yin Wind Prison, where ghosts will be blown into mime, and the process is very slow, and every ghost that is blown away by the Yin Wind will experience great pain.

The eighth prison is the beast prison, and there is a powerful three-headed monster in it, which likes to devour ghosts for food, and all the ghosts that enter here are its food.

The ninth prison is the heart prison, and there is a saying in the ghost domain that it is better to go to the eighth prison than to enter the heart prison, and the torture of this heart prison can be imagined.

The Nine Hells established by the Hell Refining Emperor were actually not far from the nine ghost cities established by the Ghost Emperor Yan. Just on the edge of the nine ghost cities, although the scale is not as large as the nine ghost cities, its momentum is not weak at all.

On the day when the Nine Prisons appeared, the entire ghost domain was in turmoil, as if they knew that the situation had changed.

Of course, it was not only the Hell Refining Fire Emperor who was active, but the Ghost Emperor Yan, another great ghost domain powerhouse whose strength was not inferior to the Hell Refining Fire Emperor, also began to act the moment the Nine Hells appeared, and it had already subdued the Nine Ghost Kings before. After that, he killed the three ghost cities controlled by the Bone Ghost King by means of thunder, directly subdued the Bone Ghost King, and got the control of the three big ghost cities.

In addition to getting the three ghost towns, the Ghost Emperor Yan also directly displaced the three ghost cities managed by the White Bone Ghost King with great power, and squeezed out the six ghost domains controlled by the Hell Fire Refining Emperor who were adjacent to the six ghost cities.

Of course, the Nine Ghost Prisons of the Hell Fire Refining Emperor are not simple, they were transferred to the other side by the Hell Fire Refining Emperor's great might, and they actually became nine sons in a row.

The battle between the Ghost Emperor Yan and the Hell Fire Refining Emperor both showed great power, but the Hell Fire Refining Emperor obviously had a slight advantage. Because of the Nine Prisons it controls, it has formed a Nine Sons Lianzhu, and it has also besieged the other three ghost cities that Ghost Emperor Yan wants, and this advantage is still very obvious.

Of course, this is not to say that the Ghost Emperor Yan is incompetent, the years when it disappeared in the Ghost Domain were older than the Hell Fire Refining Emperor, and he did not deliberately hide the nine ghost cities when he disappeared, so for thousands of years, the nine big cities in the Ghost Domain basically have owners, and they have the core tokens that control this big city. On the other hand, the Nine Prisons of the Hell Refining Fire Emperor were not so troublesome. These nine prisons have brought endless pain to the ghosts and ghosts in the ghost domain, and they are afraid to avoid the nine prisons, where do they still have the heart to want to enter these nine prisons. In addition, it has to be said that the Hell Refining Fire Emperor thought more fully than the Ghost Emperor Yan, although it disappeared, but this cleverly hid the control core of the Nine Prisons, and it was not until it returned to the Ghost Domain that the Nine Prisons were born, so as to maintain their absolute control over the Nine Prisons.

In addition to the open and secret battles between the Ghost Emperor Yan and the Hell Refining Fire Emperor, there are also some forces that are also planning their own future.

In the city of the Song Emperor of the Ghost Domain, the atmosphere has become extremely solemn, the Soul Locking Ghost King is sitting alone on a pitch-black throne, under the throne, there are a number of ghost things in the Ghost Domain, and now their situation can be said to be very difficult, the strength and means of the Ghost Emperor Yan and the Hell Fire Refining Emperor are deeply shocked by them.

"Tell me, what do you think of our future path?" The voice of the Soul Locking Ghost King became a little lost, not long ago it was still the king of the Ghost Domain, but now the situation is not so long ago, now it needs to consider whether to submit to the Ghost Emperor Yan or to the Hell Fire Refining Emperor.

"Your Majesty, our situation is very bad now, and now if we want to survive, there are only two ways, the first is to return to the Hell Fire Refining Emperor, and the second is to return to the Ghost Emperor Yan on a sunny day. These two parties are not easy to mess with, in terms of overall strength and planning, it must be that the Hell Fire Refining Emperor is stronger, but if this Hell Fire Refining Emperor is really in power, the entire Ghost Domain will become a killing place, so I am more in favor of taking refuge in the Ghost Emperor Yan, after all, when it rules the Ghost Domain, it is still relatively stable!"

"What about the opinions of the three of you?" The Soul Locking Ghost King did not judge the words of the Soul Chasing Ghost Shuai, but instead turned his attention to the three Immortal Rank City Lords behind the Ghost Shuai.

"Our thoughts are actually the same as that of Lord Ghost Shuai, now that the Ghost Domain is in chaos, the forces of the other two Ghost Kings also belong to Ghost Emperor Yan, we must also find a big force to attach to, obviously this Ghost Emperor Yan who has never seen it is much easier to get along with than the Hell Fire Refining Emperor!" The three immortal level masters also agreed with the suggestion of the Ghost Shuai to chase the soul, compared with the Hell Fire Refining Emperor, the Ghost Emperor Yan is indeed more credible.

"Okay, then let's act now, a few of you defend the city, and I will hand over the core tokens of these three cities to the Ghost Emperor Yan, I hope he won't let us down!" The Soul Locking Ghost King actually had an idea in his heart, but he was not sure, so he asked a few of his subordinates.

"Xiao Ning boy, you asked me to stare outside, and now I will tell you the news, the ghost town in front of you has suddenly disappeared!" In the Heavenly Machine Tower, the Spirit of the Purple Skylark fanned its wings and said to Xiao Ning.

"Oh, there is such a thing, it seems that the chaotic power of the Ghost Domain has arrived, we must seize this opportunity and quickly enter the core of the Ghost Domain!" Xiao Ning's eyes lit up after listening to the words of the Purple Skylark Spirit, and he made a decision at that time.
