There was one reason why the Reincarnation Kings and Lords couldn’t allow an outsider to gain the complete Dao Of Reincarnation, because what came with it was the creation of your own Pseudo-Underworld where you could receive souls and reincarnate into the planes your Pseudo-Underworld was connected to.

You may ask, why does that matter? Wouldn’t they have less souls of the dead to take care of?

Well, the answer wasn’t complicated.

It started with the fact that no matter how strong one’s soul was when he was alive, if he died, while entering the Underworld, his soul would be ground to dust, leaving behind its basic form which would be used to reincarnate. How could a newborn be able to contain such power?

For fairness, your memory had to be erased too. It was done to contain the emergence of geniuses who would cheat through many lives and achieve the result that many had spent their entire lives acquiring.

In the old times, when the Underworld had yet to belong to a single power, many used many lives to gain unfathomable power. It was a chaotic time and it was only when the Underworld was conquered by the first Reincarnation King, O’Neil Jordan, who was the strongest Dao Being of that time, that things started to look favourable.

Let’s go back to the soul being ground to a basic soul that occurred when one died.

Where would all that soul power go?

Well, it was stored at the core of the Underworld...and it would be the same for a Pseudo-Underworld.

The more soul power was accumulated, the purer the entire soul power got as there was a power that forced it to condense.

After eons of condensation, its purest form came in the form of Soul Crystals. They were so pure that even a Dao being at the 11th rank like O’Neil Jordan couldn’t manage to completely absorb a Soul Crystal the size of a string bead.

So what could the Soul Crystals do exactly?

Strengthen the soul? Yes and no. The Dao beings had tried to go past their limits but couldn’t. They’d just explode after trying to go beyond the 12th rank and have no choice but to go back to their previous bodies by resurrecting.

Then what other things could they do really?

No one knew.

It was a resource that contained so much power that no one knew how to use or dared to touch.

Many had tried using the Soul Crystals as a powersource for their invention, but even using a grain of sand of it blew what you made to kingdom come, along with your house, planet and universe… and yourself if you had the misfortune of not being a Dao Being.

Such an unstable resource really left one helpless.

As of now, the Underworld had accumulated so much of it and if it wasn’t for the fact that they were stable as long as those crystals stayed in the Underworld, the Reincarnation Kings and Lords would have to forfeit the place and recreate a new one.

Then what could the Kings and Lords of the Underworld gain by occupying the place.

First they could quickly comprehend one of the strongest Daos in the world. The Dao Of Reincarnation.

And secondly, as long as they were a Dao Being and at least Reincarnation Lord, you were allowed to use a Soul Crystal to push your Soul cultivation strength to the 12th rank Dao Being. It was the same level that a ‘supposed’ 12th rank Dao Being who had comprehended 12 Daos could reach, but just in soul cultivation. Further than that, you exploded and went back to your true strength after resurrecting.

After that, as everybody was of the same Soul Cultivation, what showed your overall strength was the number of complete Daos you comprehended.

The Underworld was a Holy Land and also an incredible cultivation resource. You can now understand why the Kings and Lords of that place wouldn’t want a competitor.

If the Kings and lords wanted to conquer all the planes known to man, no one would be able to stop them,... in theory... There were still many unknown and unexplored places that no one knew what lurked there.

The skies of the Inner Sanctum of the Underworld were filled with hundreds of puzzled Reincarnation Lords who flew to the Jail of district #6 at breakneck speed.

A King’s summon couldn’t be treated lightly.

In the furthest corner of the Inner Sanctum, O’Neil Jordan slowly opened his eyes in anger. He was on the crux of condensing the Domain of Lucidity which would bring him closer to comprehending the Complete Dao of Dreams as his 12th and last Dao. He had chosen a Dao with the least difficulty as his last one, because he was impatient to reach the peak and cement his reign over the Underworld even further.

“What does that foolish man want again? He always plays around instead of cultivating. Sigh.” Ultimately, he decided to go see what was the reason for the summons. If his cultivation had been interrupted for nothing, “Then Yammy is bound to die a few times until I am completely satisfied.”
