Under Yuan Hao's gaze, the reincarnation disk, which had been silent for a long time, took the initiative to save the Minotaur and the patriarch of the centaur clan from the heavenly tribulation, and then pulled their souls into the underworld.

Since the reincarnation disk did not take the initiative to attract the souls of any living beings into the underworld in the past, it only relied on the traction of the underworld itself on the soul, and absorbed the souls in the Tianyuan Sacred Realm with a very low efficiency.

Therefore, the Minotaur and the Centaur are the two most powerful souls of the creatures who have entered the underworld.

After the Minotaur High Priest and the Centaur Patriarch entered the Underworld, the Samsara Disk did not treat the two of them like any other soul.

If other souls enter the underworld, they will generally choose whether to become a ghost clan and live in the underworld according to the rules of the underworld, or enter the land of reincarnation to be reincarnated.

The Minotaur Priest is different from the patriarch of the Centaur tribe, and once they enter the civil realm, they are not allowed to choose, and the reincarnation disk moves them to the core of the underworld.

In the majestic palace complex that was originally empty at the heart of the underworld, some creatures have begun to move in it.

These are the ghosts who have joined the underworld at the core of the underworld.

After the reincarnation disk gave some very simple and basic duties in the underworld to these ghosts, these ghosts have begun to perform their duties repeatedly in the core of the underworld.

These ghosts and fairies were very busy when they first took office, but now that time has passed, and their fame has spread throughout the underworld, they are finally living a leisurely and relaxed life.

The main work of these ghosts and immortals on weekdays is only a few very simple things, including reincarnating some souls who should have entered the six realms of reincarnation, but have fallen behind or lost due to misfortune, so that they can be reincarnated smoothly.

Of course, this situation is rare, and these ghosts and immortals only deal with a few such things occasionally.

There were only two things they were busy with at first, or one thing, and that was to suppress the powerful ghosts in the entire underworld who were somewhat "disobedient".

The countless unconscious wandering souls that were absorbed into the Underworld from the entire Tian Yuan Sacred Realm would follow several fixed routes to enter the Six Realms of Reincarnation.

Then, the land of the six realms of reincarnation will decide for itself whether they will be reincarnated or sent to the eighteen layers of hell and tortured.

In the past, there were some ferocious ghost clans who had cultivated to the point of being very powerful, and they would make themselves even more powerful by forcibly grabbing these large numbers of unconscious geyers to devour them.

And this kind of behavior has deeply violated the rules of the underworld, and has produced some obstacles to the normal operation of the six realms of reincarnation.

In addition, there are some powerful ghosts, relying on their own cultivation to act recklessly in the entire underworld, and they are very cruel to other ghost clans.

Even, there are some powerful and ferocious ghosts who are no longer satisfied with improving their own cultivation by grabbing a large number of unconscious spirits in the underworld, and then devouring these spirits.

There are some ghosts in the underworld who have found that the more powerful the soul they devour, the more beneficial it will be to their cultivation.

As a result, among the most powerful ghosts in the underworld, some of them were very murderous and began to raise their butcher knives against the ghosts.

These powerful and ferocious ghosts have made themselves stronger by killing the ghosts in large numbers and then devouring them.

As the underworld absorbed more and more wandering spirits from the Tianyuan Saint Realm, the number of ghost clans in the underworld also began to increase greatly.

Those powerful ghosts who had already tasted the sweetness became even more tyrannical, slaughtering more ghost clans to improve their cultivation.

Under such circumstances, the environment of the underworld has fallen into a state of extreme turmoil.

Since the day of his birth, the underworld has had a set of rules of his own, and this set of rules, like the laws of the various races in the Tianyuan Holy Realm, must be obeyed by all living beings in the underworld.

The moment all the ghosts enter the underworld, they will naturally understand the rules they need to follow within the underworld.

And those powerful ghosts who are reckless in the underworld undoubtedly choose to violate the rules of the underworld even though they know the rules of the underworld.

In this case, the Yin Division of the Underworld was born.

And the ghost clans in the underworld who can have the opportunity to accept the trial of entering the underworld are all those who are strong in their own strength, but still firmly abide by the rules of the underworld, and do not act recklessly.

The powerhouses of the ghost clan who have successfully passed the trial of entering the underworld Yin Division can become a Yin soldier who is one of the lowest gods in the Tianyuan Sacred Realm.

Then these Yin Gods, under the infusion of the power of the reincarnation disk, will easily become a powerful ghost immortal.

And those who fail in the trial of the ghost clan powerhouses will not suffer any danger to their lives, and after withdrawing from the trial of entering the underworld, they will also get certain benefits according to their performance in the trial.

After these ghosts and immortals took up their posts in the underworld, their main task was to restore a stable order in the underworld, so that the underworld and the six realms of reincarnation could operate normally.

These ghosts and immortals first issued a notice to all the ghost clans in the entire underworld to strictly abide by the rules of the underworld.

Then, they selected some of the most murderous ghosts of the past, and after killing them, spread the news throughout the underworld, hoping to set an example to the monkeys.

It's a pity that the powerful ghosts in the entire underworld don't pay for it, and they have become even more ferocious than before.

Even, some extremely powerful and ferocious ghost clans began to unite, in order to ensure their high position in the underworld, they planned to attack the core of the underworld and destroy all the yin.

In their minds, if they wiped out all the shadows in the underworld, there would be no one to blame them again.

When the time comes, they can continue to act as they did in the past, and let countless ghost clans serve them, improving their own cultivation by devouring a large number of ordinary ghost clans.

However, what they didn't know was that under the absolute power gap, even any ghost immortal could suppress the entire underworld, not to mention that there was more than one yin in the underworld.
