The Formation of Life was the very core of a world. Even without a sovereign deity to control a world, it would be possible for the world to stay alive, as long as the formation was capable of keeping the energy in balance.
However, while it was not impossible for a world like Lan's to keep thriving, things were different for the Ghost Realm.
The Formation of Life was, as the name implied, a formation to keep the life and energy of a domain flourishing. However, the Ghost Realm had no life; there was no way to keep the plants growing, and the living beings breeding.
Here, the only way to enter was to be a dead soul, and the only way to leave was to vanish completely and turn into energy that others could consume.
The Formation of Life had thus gone wrong. Its purpose was to create the heaven and earth essence, but due to the lack of living beings to absorb this essence, the world was simply overburdened.
At the same time, these ghosts were unable to use the energy, and had to find their own way of survival, which had resulted in this dystopian world that no one could like.
The Black Turtle had truly wished to do their best for these lost souls, but the results had ended up becoming a prison that could not be escaped.
Lan and Xue Wei kept walking around the small dimension, and it did not take them long to arrive at the Formation of Life.
While the world was full of dark grey and gloomy colors, this formation was shining with golden light. The whole formation seemed magnificent, and one could easily see the attention and pain that the Black Turtle Clan had put in it to create a suitable formation to keep this world alive.
Unfortunately, they had not thought that a world without life would be unable to become normal.
"This looks like a treasure."
Lan had still not described the true purpose of this formation, and Xue Wei had already put his eyes on the Formation of Life in front of him. Although there was no greed in his eyes, there was scrutiny and curiosity towards the unknown.
"It is the core of this world. This is a Formation of Life, and it is the sole reason that this world has managed to keep existing, even though it is so wrong and not suitable for life."
Lan slowly began to explain the purpose of this formation and what it was capable of doing. He had no other intention than to educate Xue Wei, but he soon found that the younger man seemed to have some interesting thoughts.
"If I were to take this formation away, what would happen to this world? You already told me that the Formation of Life is the only thing that keeps the balance of the world, but the Ghost Realm has no balance. Would all the souls here vanish if I were to remove the formation?"
Lan furrowed his brows as he became deep in thought.
"The Ghost Realm is a bit of a special situation. If this was a completely independant world, then it would slowly collapse, and all things on it would become nothing, but this world is still bound to our living world, so in a way, it is also bound by the rules I have made for that world.
"This means that the souls here will not die, nor will the world vanish, but no other souls will arrive. The souls that are here depend on one another to live. If we refuse the arrival of new souls, they will slowly die, as the soul energy within will eventually run out."
Xue Wei nodded his head as he looked around once more. He was going through a myriad of thoughts, but he could not find a solution that easily.
Walking to the Formation of Life, he remembered the words that Lan had told him.
A world could either have a sovereign or not. The sovereign would be the one that would determine the world's laws, and he would also be able to change the world according to their wishes.
To become the sovereign, one had to bond with the Formation of Life.
This world was a bit special, as it was already connected to Lan's living world, but in a way, it was still independent. Although Lan was the sovereign of his world, he did not control the Ghost Realm.
Xue Wei looked at his own hands. He was still an ordinary expert, and had not crossed to the deity realm yet, so connecting with this Formation of Life was impossible. Even if he wished to try, his body would be unable to withstand the blow and explode.
He understood that he could not be too greedy, as such greed could result in his death, but he could also not help but wonder how to solve the predicament.
"You said, it is possible to control more than one realm at a time?"
Xue Wei turned around and looked at Lan, as if he finally began to forge a plan in his mind.
"Yes."
Lan began to have an inkling of what his plans were, but he was not completely certain, and he could not see the purpose of this idea, so he patiently waited for Xue Wei to fully form the plan in his mind.
"If you were to contract this Formation of Life, and then link your current world to the Diyu World you told me about once before, what would happen?"
Lan's eyes narrowed. He had actually not considered this option as he dared not connect to Diyu due to the risk of losing his lover before. But was it not an option now?
