Since this is the Netherworld, why do so many creatures appear? And why are they imprisoned here?
The answers from the three monks Fa Ke also solved Li Yan's doubts.
It stands to reason that the creatures that can enter the Netherworld must be powerful immortal cultivators, and only they can possess this kind of cross-border ability.
And these people either come here to practice, or they have something special to do, such as looking for special materials that are only available in the Netherworld, etc.
Otherwise, no living beings would be willing to appear here. The Nether World is full of strong death energy, which has a great impact on the lives and actions of living beings.
Even if a monk has a powerful physical body and is protected by his cultivation, he will often leave as quickly as possible.
If you stay here for a while, you will be transformed into an undead spirit.
This kind of conversion situation will become more likely to occur the further you go to the lower plane of Shura Prison.
So Li Yan didn't know that the strong man from the Yin-Yang Chaos Sect also left immediately after the result.
The first floor of Shura Prison where Li Yan is located is a special existence. It is located on the edge of the underworld. It is also a place where death energy and spiritual energy alternately appear.
But in general, death energy accounts for 80%, and spiritual energy only accounts for 20%. This is a place where those who cannot enter the path of reincarnation are punished for the souls after death.
Above the first floor of Shura Prison is a place called Huangquan City. It is also a place where death energy and spiritual energy appear alternately, but spiritual energy accounts for 80% and death energy accounts for 20%.
And in that area, there is really only one city, the only Huangquan City, and the rest is an endless open area.
Because the area where Huangquan City is located is difficult for people to survive, only one city was built later.
The origin of Huangquan City is said to be the last barrier specially set up by the Netherworld in the Yang Realm. There is a Naihe Bridge there, which is the entrance to the dead souls.
At the same time, there are also sects established by many ghost sects in the Yang Realm in the city. The power of such sects in the Yang Realm must also be very powerful.
Otherwise, the Netherworld will also look down upon it and will not have any contact with it.
Because of the laws of heaven and earth that separate yin and yang, strong men from the underworld cannot easily come to the world, and it is also very difficult for strong men from the yang world to enter here.
However, when some powerful people reach a certain level, they can rely on their tyrannical strength to travel between the worlds of life and death.
Huangquan City is the only way outside the Netherworld that living beings can enter and exit.
Because of the strong aura of death, under normal circumstances in Huangquan City, apart from a small number of ghosts that attract the souls of the dead, there are mostly ghost sect monks.
The ghost cultivator will help the ghosts of the underworld do some things in the Yang Realm, such as obtaining information in time, obtaining resources that are only available in the Yang Realm, etc.
As for those ghost sect monks, because they practice ghost cultivation techniques, they can get more promotion in Huangquan City. This is the main reason why they are willing to set up a branch sect in Huangquan City.
And if they do relatively well in certain things, they may even be allowed to enter the real Netherworld to practice, which is also something that many ghost cultivators dream of.
Of course, only powerful ghost cultivator sects can know about such a secret place. Ordinary ghost cultivator sects will never know about the so-called Huangquan City.
After Li Yan learned this news, he had some speculations. He felt that a large sect like the Demon Sect might also have some top-secret information about the Netherworld.
But things of this level would not be told easily, even if Li Yan was already a monk in the Void Refining Realm, he would not be told easily.
At the same time, the Demon Sect would never have thought that the disappearance of people like themselves was actually related to the real Netherworld.
There has never been direct communication between the Yin and Yang realms. For example, the Nether Realm communicates with the Yang Realm through the ghost cultivators in Huangquan City, so there is rarely any talk of attacks across realms.
This made Li Yan even more confused after knowing the role of Huangquancheng. He couldn't figure out why the other party wanted to attack people like him across the border?
Cross-border attacks, even with Li Yan's knowledge, he knew how difficult it was and how much it cost to do it.
Even if the lives of all of them combined this time, it is simply not as high as the cost of this cross-border attack in the Netherworld.
After Li Yan learned the news about Huangquancheng, his heart suddenly jumped up and down.
If I guessed correctly, the yellow aperture ring layer encountered in the bottomless black hole should be the location of Huangquan City that the opponent passed through when opening the passage between the two realms.
Based on this speculation, Zhao Min and the others are most likely to have entered the scope of Huangquan City, which is considered to be on the edge of the junction of Yin and Yang, and is a special area.
Zhao Min and the others want to return to the Yang Realm through Huangquan City, but this hope is undoubtedly extremely slim.
The ghost cultivating sect there is connected to the Netherworld. I wonder if the ghosts here will pass on information and let people arrest Zhao Min and others?
This situation is very likely. After all, they are crossing borders to deal with people like them, but Li Yan can't do anything now if he is anxious...
Later, Li Yan asked if any new monks besides him had been sent here recently?
The three of them were already on the verge of collapse, but when it came to these matters, Li Yan asked him several times from time to time, and the three of them always insisted on denying it.
It was confirmed that no new monks had entered here for at least four months except Li Yan. This made Li Yan both disappointed and a little relieved.
He felt that Chu Yinghong might have escaped this disaster, which would also greatly increase the chance of survival of those cultivators of the Demon Sect.
But on the other hand, Li Yan completely lost his trustworthy helper and could only rely on himself for everything.
As for the origins of all the creatures in this prison, Li Yan quickly figured out the reasons.
After all, all the creatures here entered the first level of Shura Prison through Huangquan City. It can also be said that they were captured and sent here from there.
Of course, Monk Fahe and the other three did not know the way Li Yan was captured, but they were completely different from them, otherwise they would have been extremely surprised.
The origins of the monks here are very complicated. They come from different realms of the fairy world. This alone surprised Li Yan.
And the reason why they appear here is that they basically have one thing in common.
It was when exploring different secret realms or practicing outside that I accidentally entered the space node passage of Huangquan City.
In fact, those node passages are hidden traps deliberately set by many ghost sects in the human world.
Then they were involved in Huangquan City, and the ghost cultivators in Huangquan City were deeply hostile to the monks from other sects.
This is just like in the outside world, most sects treat ghost cultivators and soul cultivators because they want to kill them because of their weird methods to avoid future troubles.
Once a monk enters Huangquan City, it is simply more difficult to return to the fairy world than to climb to heaven.
Basically, the ghost cultivators will try their best to capture the monks who enter Huangquan City alive. If this is not possible, they will kill them in a fight.
The reason is that there is a great need for living beings in the first level of Shura Prison.
On the first floor of Shura Prison, there is a ghost plant called "Bana Flower", which is of great help to ghost cultivators and ghosts from the underworld.
Of course, the cause of this incident cannot be traced back to the specific time, but Li Yan still figured out the reason for picking the "flower of the other side"...
Due to the special location on the first floor of Shura Prison, the "Bana Flower" that has been around for more than three hundred years has the power to communicate Yin and Yang.
Within the flower, there will be a kind of intertwined perception of the critical point of yin and yang. Once the understanding is thorough, it will make a qualitative breakthrough in one's own cultivation.
It is precisely because of the special nature of "Bana Flower" that it only grows on the first floor of Shura Prison, and no such ghost plant will appear on the following seventeen floors.
However, this material cannot be used directly. It must be harvested and then refined into elixirs with the help of other materials before it can be truly used.
But when picking the "Flower of the Other Side", once a ghost from the netherworld comes into contact, both his consciousness and his body will be devoured by the flower.
And because there are roots to support subsequent strength, the ghosts will be more seriously harmed at the moment of picking.
But if you want to ingest it through the air, after refining the elixir from the "Bana Flower", it will be difficult to realize the intertwined perception of the critical point of yin and yang, and it will basically be of no use.
Moreover, they also discovered that once the Bianganhua was touched by spiritual consciousness or body, when they touched it again, the phenomenon of absorbing Mingshou would no longer appear.
After this situation occurred, at the very beginning, the Netherworld ghosts thought of the ghost cultivator who was cooperating with them, and wanted to see if the ghost cultivator could pick it directly.
The elixir refined by "Bianganhua" is also of immeasurable help to those ghost cultivators.
A group of ghost cultivators were dispatched from Huangquan City and entered the first level of Shura Prison. However, after that and the only time of picking, the ghost cultivators immediately retreated.
Because those ghost cultivators also found that their life span was greatly reduced during the picking process. Every time they picked a "Butterfly Flower", their life span would be reduced by about a decade.
Moreover, the older the "flower of the other side" is picked, the more life span will be sucked away from that person. At the same time, the pain of instantly draining life span is basically being ripped away from the soul.
Even monks who thought they could endure pain would end up rolling on the ground in pain just after picking one flower.
Fortunately, the longevity essence absorbed by "Bana Flower" does not absorb continuously. It also only takes away part of the opponent's vitality in an instant during the first contact.
And those "Flowers of the Other Side" picked by the ghost cultivators were also refined into elixirs. To the great joy of the ghosts in the netherworld, they actually produced a stronger sense of intersection of critical points.
This made them guess that this may be a kind of self-protection of the "Bana Flower". All things have spirits, not to mention this weird thing that grows on the edge of Yin and Yang.
Moreover, when the "Bana Flower" protects itself, some kind of power may be released from within the flower as a final defense.
The power released can never be recovered after the flower leaves the rhizome, and that power is the source of a strong sense of critical point intersection.
