The situation was serious enough to prevent any distraction, but Yale couldn't avoid being expectant about if the Mysterious Expert would reveal its identity or not.
After all, Yale had known about the existence of the Mysterious Expert for a lot of time, but he had never managed to deduce its true identity.
"Alright, I will tell you, but my existence will be erased soon, so I don't know if you will be able to remember about my identity or not. Well, maybe you will be able to it."
Since the Mysterious Expert already decided to tell Yale the truth, there was no reason to delay it more time.
Moreover, the Mysterious Expert knew that given the power of the Existence Eraser, there was no way to last too long blocking it.
"First, you need to know that I don't have a name because from the start someone like me shouldn't have existed."
Yale wasn't able to understand why someone shouldn't exist, but he continued to listen in silence.
"At the start, I was merely a will created from the resentment created by this war. The despair of the dead people, their unfulfilled wishes, their hopes for a future that didn't have a chance a to happen, and a lot of other emotions were what created me, but at that time I didn't have a consciousness. I just existed as a will that supposedly no one could see, but someday that changed…"
Yale had difficulties to believe that story because the fact of such a powerful expert being born from the dead people in the war wasn't something that could happen as far as Yale know.
"Our universe had already fallen in dire straits, and it was almost destroyed. The few survivors, they battled with all their strength to survive, but the situation was too dire to change it at that point."
What the Mysterious Expert was telling didn't match with the story Yale knew about the universe, but that time, Yale understood the reason for it. After all, the Mysterious Expert was also a Timeless Sovereign, so Yale could guess that the Mysterious Expert did something to undo that part of the story.
"The first person to notice about my existence was part of a group of five that were battling against an army that they couldn't defeat. I can't remember who of the five noticed me first, nor what led them to make the decision that they made."
Yale felt that the Mysterious Expert was already reaching the most important part of the story.
"The five of them offered their existences to me using the power of the legacies they owned, and thanks to that, I obtained a body that was born directly as a sixth level immortal. That was also the first moment I obtained a consciousness."
Yale was flabbergasted after learning that the Mysterious Expert was already born being that powerful, and at the same time, he understood why the Mysterious Expert existed despite its origins as a mere will.
There was no doubt that was thanks to the five who sacrificed offering their existences.
"The first thing I did was exterminate that army. After all, I also obtained the memories and feelings of those five, and my original existence also had a boundless hatred against them."
A sixth level immortal was devastating without any other sixth level immortal, so it wasn't difficult to imagine the outcome of that battle after a sixth level immortal appeared.
"Who were those five?"
That was the first time Yale interrupted the Mysterious Expert, but after hearing the number five and the word legacy, he had a feeling that he knew who were those five.
"Those five who sacrificed themselves to let me become a real existence were Aknarel, Shiba, Lina, Gerken, and you."
The Mysterious Expert just confirmed what Yale had been thinking. The legacy that helped to create the Mysterious Expert was the universe creator's legacy, the same one that had just disappeared to protect Yale.
Moreover, just as Yale thought, the owners of the pieces were the same he knew.
"After killing that army, I wanted to change everything and create a different future, which ended up with me becoming a Timeless Sovereign after traveling to the past. However, undoing that war also undid my own reason to exist, so my existence became unstable, and I could only exist as an incarnation that shouldn't leave the universe from that moment on."
The Mysterious Expert continued with the story without waiting to Yale's reaction after revealing the identities of the five who sacrificed themselves.
"I never minded about that because I was still strong enough to change a lot of things and prevent a lot of calamities. I have been especially focused on the five who sacrificed themselves to let me exist as a sentient being. With my actions I prevented Eini's death to help Shiba and Lina, I saved Gerken's Heaven Academy from an incident that would have killed all the teachers and students, and I also helped from the shadows to prevent that your planet was destroyed. However, the only one of the five who had a messed fate due to my actions was you."
The Mysterious Expert wanted to help the five of them in order to thank them for their sacrifice, but for the sake of the universe, the Mysterious Expert needed to mess with Yale's fate too much.
"Do you know something interesting? Until we escape from this war, the only two existences allowed to become Timeless Sovereign are the universe creator and yourself. The only reason I became one was that you sacrificed your existence to me. However, for that same reason, I needed you to become a Timeless Sovereign, that was a must to finish this war."
Yale didn't know why he was allowed to become a Timeless Sovereign while others weren't, but he felt that it should be related to that strange curse of the universe.
"I always felt that you should kill me. Of the five, you are the one I harmed the most, so you have the right to kill me. After all, my existence is incomplete, and unless I absorb the five of you again, I am doomed to disappear someday, but I have never planned to absorb all of you just to prevent my death. I want to end this war, but I also hope that you five survive to it. You five let me become a living being even though it has been just a limited time. That is enough for an existence that should have never become a sentient being."
Since the Mysterious Expert knew that its time was limited, it decided to speak about all his feeling to Yale with the hope that he would also tell them to the other five someday.
In fact, even if the Mysterious Expert absorbed all of them, without the universe reaching the same state as when the will of the Mysterious Expert was created, the Mysterious Expert would still disappear someday and going to another universe would hasten the process.
There was something else that the Mysterious Expert didn't know, but one of the conditions to exit the loop was that the Mysterious Expert disappeared.
The Mysterious Expert existed thanks to the loop created by God's Punishment, and its existence couldn't be allowed outside of the loop.
After all, in normal circumstances, not even those five sacrifices would have created something like the Mysterious Expert. It was the God's Punishment inside the legacy of the universe creator which provoked it.
The Mysterious Expert was someone that the universe needed in that war, but its existence wasn't allowed outside the loop created from the war, so the only way for the Mysterious Expert to exist was living in a constant loop with the war repeating without end.
"I don't know what I did in the time you came from, but I currently don't harbor any hatred towards you. I know that you never had any ill intention towards me."
The Mysterious Expert could have messed up with his fate, but that was also the reason for Yale becoming the person he was at that moment. Without those interferences, Yale doubted that he would have been able to battle with the Supreme God in that war to the point that the Supreme God was forced to use his trump card.
"I am glad to hear that."
The Mysterious Expert turned towards Yale and smiled.
Yale wasn't sure of what face had he seen because he felt that has seen a lot of people at the same time, although there was only one face. Of course, Yale's own face and the other four who sacrificed themselves also were among those.
The Mysterious Expert didn't have a fixed form, but it could turn into any of the persons that created its will or that sacrificed to give it a body.
At that moment, when the Mysterious Expert was about to disappear, Yale had seen everyone that was related to the existence known as Mysterious Expert.
Everyone was smiling as if they had fulfilled their purpose in life while the Mysterious Expert started to disappear.
"The time is over. You must resist the rest of the Existence Eraser and then finish this war."
The body of the Mysterious Expert disappeared as Yale receives a last message in his mind, but it wasn't with the voice used by the Mysterious Expert, but from countless voices.
"We entrust our hopes to you."
Determination shone in Yale's eyes after hearing those words.
