He expects that the conflict will start with the Vulcans complaining about the disparity in their large population size and small space of their territory to the Sun King.
After that, he predicts that the Sun King will then ask the Snow King for more space to expand the territory of the Vulcans.
Arthur is willing to give the Sun King some grace and say that the Sun King will ask for more space politely. But he also knows that no matter how polite the Sun King is about it, the Snow King won't listen to him and will reject his request.
He expects the Snow King to say, "The space we have is what we fought for. We need it to expand our population. If we don't have a large space, how can my people prosper?"
This will anger the Sun King, who will then say, "Since you fought for this space, why don't I fight you for it?"
And so a war will happen.
After thinking about this, Arthur shook his head and said, "Invaders come to kill you, or you kill yourself. What difference is there between invaders killing you and you killing each other? At the end of the day, death is death."
There are some people in the Blood Skull army who don't like coming to this world to kill people for resources. But he doesn't see any difference in who does the killing.
In fact, he thinks that their reason for invading Aries is better than some of the reasons that people kill each other for. He can say this with confidence because of the experience of his past life.
In his past life, he knew humans can kill each other for religion or nationality, or simply because of the difference in skin color, or even for pleasure. So he can claim the high ground here because the Blood Skull army came here to kill for resources and nothing else.
What's more, their invasion of this world will grant this world mana, which will allow the people of this world to grow stronger and prosper. Not many people can make the claim that they left a place they invaded better than it was before they invaded it.
Of course, not everyone will agree with him on the matter that Aries will become better before their invasion. The previous Sun King and the world spirit of Aries will definitely disagree with him on the matter.
Unfortunately for the two of them, their opinion on the matter doesn't matter. The old Sun King is now dead, so whatever opinion he had about the invaders has gone to the grave with him. As for the world spirit, she is too weak for her opinion to matter.
The world spirit didn't want to die, but just like the Sun King, there was nothing she could do to change her fate. The Domain of the Ethera tree had become too strong to stop.
The Domain could now spread on its own. So even without the mobile fortresses dragging the golden hands of god forward, the domain was able to expand.
In just one month, the domain spread to cover 10% more of the world. This made a total of 50% of Aries that the domain of the Ethera tree had subdued.
This sealed the fate of the world because the world spirit can not harm the domain anymore. After all, the influence of the world spirit over Aries is now equal to that of the Ethera tree.
This change also improved the power of the two Sovereigns. Their power was raised from 5C to 20C. This was further increased to 50C after the domain spread to cover 60% of the world.
After the domain covered 60% of the world, the world spirit became too weak to survive in the presence of the Ethera tree. It was crushed by the domain and died.
Arthur didn't know how the Ethera tree killed the world spirit. All he saw was that a phantom of a giant golden tree suddenly appeared in the world. Then the phantom of the giant golden tree materialized and became a physical object.
The death of the world spirit allowed the domain to instantly cover Aries. Aries became the domain of the Ethera tree, so they didn't need to continue to spread it. This also marked the end of the campaign of the Blood Skull army in the world of Aries.
The goal of the Blood Skull Army in this campaign is to repel the gem people. All along, they have killed a lot of gem people, but they have never been able to cut off the communication between the gem people still alive and their home world.
If they are to get rid of the gem people completely, they will have to search every inch of Aries, seizing the smallest leystone and killing the weakest gem people. Not only that. They will also have to move Aries from its position completely in order to prevent the repeat of how the gem people gained access to Aries in the first place.
After doing all of these, they will have to hope that the gem people don't find Aries by luck. But after Aries became the domain of the Ethera tree, they didn't have to do all of those things anymore.
With the Ethera tree now in total control of Aries, the crystal shell surrounding Aries at the third layer of space can now be strengthened. The strengthening of the crystal shell immediately severed the connection between every leystone within Aries and those outside of it.
Thanks to the strengthening of the defense of the crystal shell of the world, the gem people won't be able to enter Aries anymore. As long as the gem people don't have something more powerful than the Ethera tree, they won't be able to bypass the crystal shell for communication or for reinforcing Aries.
With this development, the Blood Skull army can leave Aries knowing that they have tried their best for Aries. After all, anything that can bypass the defense of the Ethera tree is way out of their league to handle.
