Chapter 536: A Complete Retrospective, The Vanishing Line of Eren's Death (Part 1)
"You have to succeed, please, Alsteed, please, Aisha!"

"It has to succeed!! It has to be!! Dig Eren out of his grave!! Please!!!"

"bye!!"

"Yeah!!"

Rudy, with his eyes tightly shut and veins bulging on his neck, shook his hands vigorously on the large bed in the royal palace of Notos, and with a roar, kicked his legs and jumped off the bed.

A crow was flying in an airplane and landed headfirst on the ground.

"Ouch!! That hurts!"

He sat up from the ground, clutching his head, and opened his eyes groggily.

Thick curtains covered the windows, making the room dimly lit. A lingering, alcoholic odor filled the air, leaving him somewhat bewildered.

Rudy stared blankly at the carpet beneath him, and after a long while, he let out a long, sullen sigh:
"I fell asleep. When did I get home? Hmm... Hmm? What did I do after the time magic? I can't remember anything at all."

After muttering a few words, he shook his head, only to be met with a sharp headache—the familiar feeling of a hangover.
"Ah, so you went drinking. Hehe, no wonder you felt dizzy."

He glanced at the bed.

—In the darkness, a blonde girl was covering herself with a blanket. Her face was blurry but her expression was vaguely visible. She was staring at him with wide eyes.

Seeing this, Rudy smiled gently, rubbed his forehead, and said, "Sarah, could you get me a glass of water? I'm thirsty."

Before she could finish speaking, Sarah reacted strongly, jumping out of bed and storming off. She walked to the window and flung open the thick curtains with a whoosh.

"Sarah?! Do you know who I am?!"

The orange rays of dawn from Yarsh pierced into the room, illuminating it.

The spacious bedroom featured bed sheets embroidered with gold thread, a soft carpet, clothes scattered all over the floor, and a half-empty wine bottle.

Rudy was taken aback, as if he couldn't figure out where he had been sleeping.

Then he suddenly opened his mouth wide and looked at the person in front of the window.

The blonde girl, with her long hair reaching her waist, had an angry expression on her face, her eyes wide as she stared at Rudy.

Where is his dashing wife with short blonde hair and a background as an archer?

Rudy jumped up with a start, exclaiming in astonishment, "Oh no, I came to a brothel drunk?! Wait! Something's not right! What brothel has such a luxurious bedroom?"

As soon as she heard that, the girl was furious. She grabbed a few pieces of clothing that were scattered on the floor, hugged her pillow, and stormed out the door.

"I thought the young master of the Notos family was a decent person, but I never expected this to be your true colors. I was blind!"

Rudy was stunned again, then covered his head with his hands, his expression changing drastically.

In that short time, he was awakened from that long-lasting dream that had stretched for many years, which was actually half of his life. Memories from before he fell asleep suddenly flooded his mind.

—The news of Allen's letter was revealed by the First Prince, and as a result, the Boreas mansion has been inundated with visitors for the past few months.

After that, the nobles, finding that they couldn't find Allen at all, turned their attention to their own Notos family heir, who had been forgotten for two years and was on good terms with young master Boreas.
Is this what they call playing favorites?! I, Rudeus, will certainly not yield!
He took aphrodisiacs!

I went on a buying spree of aphrodisiacs!!

Ah! That's perfect! I, Rudeus, love eating the finest rice from the noble ladies of the capital! Although she has no muscles and her figure is a bit out of shape after taking off her corset, she's fair-skinned enough!

Fair skin can cover up a hundred flaws, not to mention these noble ladies are all quite beautiful!
Then last night, through Philip's introduction, Rudy met the second daughter of an earl. Good heavens, it was like dry wood meeting fire. After dinner, a walk, moon-gazing, and drinking, things progressed smoothly to the final step.
At this critical moment, Rudy's mind was racing!
What was her name again?! Remember! Remember!!
Oh!! That's right!! Ellenras!

With a creak, the door was pulled open, and the newly recruited maids outside were all suppressing their laughter. When they saw that the girl they thought would be the future mistress's boyfriend last night came out, they quickly stopped laughing and bowed in unison.

Rudy, no longer caring that he was naked, hurriedly said, "Sorry! Sorry! Ellenras! Listen to me, I had a very vivid dream, so I was a little confused just now."

A pillow was thrown in from outside the door, knocking Rudy over with perfect aim!

All that remained was an even angrier, more frantic shout as she walked away: "My name is Lun-er-ela-s!!! Lun-er-ela-s!! Get out!! Don't let me see you again!!"

Rudy scrambled to his feet and saw the other person getting dressed and walking downstairs. His lips twitched for a long time, but he was too ashamed to ask the other person to stay.

There's nothing we can do, really nothing we can do! Your name contains both Ai and Lun, so it's perfectly normal to get the order wrong!
A soft laugh came from outside the door.

The maids could no longer hold back.

Although the maids only came to curry favor with Nottos after he regained his power, they were still well-educated maids.

But they couldn't resist the fact that young master Nottos was so approachable. Spending time with him had emboldened everyone, and sometimes they would even tease him.

Seeing this, Rudy became furious and shouted, "Stop laughing!"

The maid held back again, her face tightening as if she had changed her expression, and she bowed very seriously, asking, "Young master, would you like me to help you change your clothes? Or would you like to wash up first?"

Rudy glanced at them and quickly covered his private parts:
"I want to take a bath! Go and prepare some bathwater for me!"

The door closed, and the laughter resumed before fading away.

Rudy was left sitting on the ground, his face ashen, questioning the meaning of life.

-

A short while later, Rudy, having finished washing up, was dressed neatly with the help of a maid and came to his study.

After dismissing his attendants, he plopped down in front of the magic circle blueprints piled up on the entire table and fell into deep thought.

Where is my wife?
No. What am I thinking?
Rudy looked at his body, which was definitely not middle-aged, clenched his fist, reached out, clenched his fist again, and then shrugged.

Doubtful.

Then he saw the letter Allen had written to him on the table, a letter that had been read many times. He paused for a moment, then chuckled and shook his head.
Was it because Allen suddenly sent a message that I missed him and had such a bizarre dream?
However, it was too realistic and vivid. A short dream lasted for so many years. Alan was actually killed by Alsteed? Haha, how could that be? Why would Alsteed kill him? It must be that the scene of Alsteed killing someone left me with psychological trauma.
As he spoke, his smile suddenly vanished.

The image of Sarah holding her child, standing behind the curtains with a sweet smile, remains vivid in my mind.

Rudy remained silent for a long time before scratching his head.

"Sarah is such a nice name."

As he spoke, he picked up the drawings of the Milis healing technique he had drawn last night, frowned and looked at them for a long time before picking up a quill pen to continue sketching the drawings.

The pen tip hovered over the drawing for a long time without falling.

Finally, muttering to himself, "It still feels so real," he flipped the drawing over and began to write.

However, it was not a blueprint for a magic circle.

Instead, he wrote down the conclusion of the dream, the few months that followed, and the judgments and speculations Orstide made about the nature of the world:
Worldline Theory:
According to Lord Orsteed... (crossed out), according to the information revealed by Orsteed:
The reason time magic is a forbidden art for dragons is not because it is too useful, possessing the divine power to change all regrets, making it unsuitable for everyone to master. Rather, it is because it challenges the world rules established by the creator god, carrying a fatal price.

The dragon race once listed it as a forbidden technique, but they couldn't bear to give up its divine power, so they improved it in a way similar to exploiting a bug, creating a reincarnation technique that doesn't challenge the rules of the world.

—It sets a starting point for reincarnation and an end point for reincarnation; the time in between is the cycle of reincarnation. During the period when the Reincarnation Secret Technique is in effect, those protected by the Reincarnation Secret Technique simply reincarnate continuously within this predetermined time, changing the world.

However, the Reincarnation Technique itself is like a black box containing Schrödinger's cat. Before achieving the TRUE END and escaping the Reincarnation Magic, the constantly changing worldline within the Reincarnation cannot be integrated into the true worldline outside the black box.

It avoids the cost of time magic in a unique way, yet still allows one to enjoy the convenience of returning to the past.
-
The cost of time magic:
As the name suggests, it is a dragon clan secret technique that reverses time and allows one to return to the past.

It challenged the world rules established by the creator god, and came at a fatal cost:
— It was despised by the lingering will of the creator god that remained in the world after his death.

The caster will be annihilated by the magical turbulence of time and space at the moment of returning to the past, in order to maintain the stability of the world line.
-
Is there any possibility that time magic could succeed?
Orsteed speculated that as long as he could use the Reincarnation Secret Technique to return to the past at the very moment of death, just one instant after completing the time magic, he could achieve his goal.

This would allow them to steal a period of time from under the nose of the creator god without affecting the world line, thus gaining space to survive.

However, time flows normally, and the person who uses the secret technique of reincarnation will surely return to the moment before their transmigration.

At this point, the reincarnation technique ends, and the true timeline begins; the caster will still die.
-
Divine twins and the theory of world destruction
According to Austerd:
There are two gods: the creator god and the destroyer god.

The former created the world, transformed his own corpse into magic, and his remaining will into the rules of the world, protecting it.

The latter, however, awaits the destruction of the world.

The six-sided world has a lifespan. The magic power transformed from the corpse of the creator god is the energy that sustains the existence of the world. The moment the magic power is exhausted will be the moment the world is destroyed.

The other half of the Creator God, the Destroyer God, will personally destroy the world and return it to its original state.

Similar to the Big Bang theory.
-
Neutralization effect:

Allstead revealed that the Creator God favors certain destined individuals, seeing in them the possibility of preventing the destruction of the world, or rather, cause and effect.

So He turned His gaze upon these people, using His remaining will to protect these people destined by Heaven.

I call it—the power of destiny.

Then the question comes:

The Creator God will perish those who use time magic to threaten the stability of the world lines; He despises them.

But He will favor those who are useful in preventing the destruction of the world, watching over them and protecting them.

What would happen if these protected people, who possess the power of destiny, used time magic?
Will the remaining will of the creator god choose to protect them or annihilate them?

Speculation 1:

Upholding justice even at the cost of one's own family:

Rules have no eyes; He chooses to continue to strangle these disobedient children.

Speculation 2:

Double standards:

The Creator God will show them leniency, using his remaining will to clean up the mess for these chosen ones.
-
The Butt-Wiping Theory:
In the dream, Alsteed and I believed that Speculation Two was closer to the truth.

He presented a piece of evidence:
Allen's appearance has changed inexplicably.

When Orsteed found the Seven Stars, he discovered an unidentified corpse that had descended upon the Six Dimensions along with the Seven Stars.

I also revealed that Allen often makes some precognitive, prophetic gestures.

Based on these two points, Auersted deduced:
If Allen is not an apostle of God and man, then he must be someone favored by the creator god.

The moment he descended into this world, he used the secret technique of reincarnation to be reborn into the body of Allen Boreas Grellat, who was once just an ordinary mortal, which made his name extraordinary.

After living like this for some time, they arrived at the end of the Reincarnation Secret Technique, which was the time when the Great Transfer took place.

Allen's true form has arrived.

To clean up the mess left by Allen, the chosen one, the Creator God merged Allen's original body, which shared the same soul, with his reincarnated body.

That's why Allen's appearance changed.
-
The theory of smart toilets:

Even if the creator god were willing to clean up the mess left by the chosen one who uses time magic, the timeline is objectively divided into two.

According to the worldline theory, both worldlines at this point are unstable, challenge the rules of the world, and are disliked by the creator god.

What will He do?
The answer is, keep wiping your butt.

Just like a smart toilet, it automatically dispenses water and tirelessly wipes your bottom.

How exactly do I wipe it?
Similar to merging two bodies, given the right conditions, He would decisively choose to merge two worldlines into one.

The reincarnated world line, or rather, the one more favorable to the chosen one, will be taken as the true world line.
-
Rudy paused for a moment, resting his chin on his hand, and continued writing:
-
In my dream, I asked Auersted what "under certain conditions" meant?
Allstead replied: The remaining will of the creator god left only the rule of strangulation, but not the rule of your kind of "wiping your ass" theory.

Therefore, the limit of what He could do was to unite the physical body into one.

Changing or merging timelines is too difficult for the remaining will.

I asked, "How can it not be difficult?"

After a moment of silence, Alsted looked at me and replied, "The Divine Jade is the divine power left behind by the Creator God, and it is also the manifestation of the rules He left behind. If the Divine Jade is burned, it can change and reshape the rules to the greatest extent."

I asked him, "How did you know?"

After a long silence, Alsted replied, "I come from the distant past. My very existence, and the centuries-old secret technique of reincarnation within me, are the result of burning the divine jade."

I pressed further: "Is there any way to correct the course of our worldline, this worldline filled with regret, this timeline brimming with remorse, to go back to the past, to melt into the past, and to become that real worldline?"

He remained silent for a very, very long time before finally speaking:

"It's very simple. The moment Aisha Notos Greirat casts time magic to return to the past, all I need to do is burn the divine gem I possess and pour my magic power, divine power, and life force into Aisha Notos Greirat's body."

I was stunned for a long time, then lowered my head and asked:

"It's just a speculation, isn't it? Although you have a lot of evidence, you can't prove that the inference is completely correct."

This time, Alsteed responded to me without hesitation.

He said, "Try it and you'll see."
