Are you worthy of saving the world?

"..."

After a long silence, Rosalia accepted Yuli's statement.

"But...compared to this, how did you know?"

Yuri then explained to her the "someone" he and Celestia met during their adventure.

A black knight who claims to be "Four Heavenly Kings·Double Phantom Fifth", but in fact he is not on the list of the Demon King's army.

"In other words, the guy you met at that time, the double phantom Faith, is your future self?" Rosalia asked back, pinching her chin.

As expected of her, she is the "Empress", Yuli sighed in his heart.

It is easy to explain to a smart woman, and it saves him a lot of time.

Originally, Yuli felt that it would take at least half an hour for Rosalia to understand time travel and logical closure.

For time travelers like Yuri, time travel and loop-themed movies and animations are already common themes, but Rosalia has never been exposed to these contents.

Yuli was surprised and pleased that she understood immediately.

"So next, you want to reverse time and go back to the hot spring town a few weeks ago to talk to your past self...right?"

Yuri nodded and said, “It was at that time that I first learned about the existence of the Mirror Temple from the conversation.

If I don’t complete this “past”… “The present me in the Mirror Temple” will no longer exist, and it might be corrected by the law of causality.”

After Yuri finished his explanation, the two began to check for hidden mechanisms in the temple.

They injected magic into every mirror in the prism space.

Soon, new discoveries were made.

"Yuri!"

Rosalia called Yuli to her side.

After the magic power was injected into the mirror in front of the Grand Duchess, words appeared.

The above describes the methods and principles of time travel through the Mirror Temple.

Two things stand out in particular:

"The Mirror Temple can only perform time manipulation three times."

"When traveling through time, you cannot change what has already happened in the past, otherwise the law of causality will modify it."

"and many more……"

Looking at the words appearing in the mirror, Rosalia suddenly thought of something.

As expected, she noticed it. Yuri sighed.

Rosalia asked: "Who was the first person to find the Mirror Temple? Who was the person who left these words for us?"

"The Yuri of the present" informed "The Yuri of the past" about the existence of the Mirror Temple.

But who discovered this Mirror Temple in the first place?

"..."

Yuri was silent for a moment, then answered truthfully.

"We are probably in the world of 'Second Round' right now."

"Second round...?"

Yuli raised his right hand and showed her the note in his hand and the words on it: “The Mirror Temple was not discovered, but was built by humans.

The man who built this temple and left us this mocking note -

It's definitely Ulysses and Rosaria from "First Round", you and me."

"........."

Rosalia's mouth dropped open.

“I guess that in the world of the first week, Celes still couldn’t escape the fate of death.

After her death, the two of us destroyed the lich Leoric, and then spent ten or even dozens of years searching for clues to time travel and resurrection magic in this world...

Finally, we built this Mirror Temple, used it to start the second round, and added new elements. "

The text that appeared in the mirror explained how to start the "Second Round".

Starting a new round will cause slight changes to the world structure.

It is precisely because of the new elements added by starting a new round that Yuri was able to come into contact with the existence of the Mirror Temple from scratch.

"So, in Act 1, what about us..." Rosalia murmured.

"Rosa and I have lived in this world together for decades," Yuli said with a relaxed expression.

"Well……"

Rosalia bit her lip and finally couldn't help asking.

"How can you be sure that it was the two of us who built the Mirror Temple? The handwriting on the note is yours. Maybe it's only you, Yuri..."

"That's natural, right? If I were alone, I wouldn't be able to hold on. The most important thing is..."

Yuri looked at her and said, "In the last... the first episode, I disappeared because of the correction of the law of causality...

If Rosalia hadn’t been by my side, I certainly wouldn’t have had the courage to face the unknown future calmly.”

"Yuli..."

Rosalia squeezed his hand.

Unbeknownst to herself, she and her beloved had been working and living together with the same goal for decades.

In the end, the two of them stood shoulder to shoulder, welcoming disappearance together without any regrets, and looking forward to the next cycle of reincarnation.

A little... romantic.

"It's a bit regrettable that we have to use contraceptive magic for decades... After all, if the child is kept, we won't be able to start the second round." Yuri said with a sly smile.

"It's already this time... idiot!" Rosalia kicked him hard with the toe of her high heels.

Although Yuri's explanation was very reasonable, the Grand Duchess still looked confused and uneasy.

"But Yuri...even if you go back in time, history won't change, right?"

"When traveling through time, you cannot change what has already happened in the past, otherwise the law of causality will modify it."

Rosalia quickly realized the huge limitations of the Mirror Temple through the written description.

In other words, time travel cannot change the past, otherwise they would not have pinned their hopes on the second round.

Even if Yuri went back to the past, he could only disguise himself as a double phantom and tell his past self the Riddler dialogue he had heard.

He couldn't just tell Yuri in the past, "Ceres will die soon, you have to protect her well!"

Can't--

All "present Yuri" can do is repeat what he has experienced before: reveal the location of the Mirror Temple to his past self.

Rosaria bit her lip, her pupils trembling: "Ceres will still consume a lot of her divinity in the adventure... and then be attacked and killed by Leoric.

Even if we go back to the past, we can't change anything...

Time will continue to repeat, again and again... Ceres will be killed, and we will come here...

It's like we're trapped in an infinite loop... we can never get out... Yuri?"

At this time, the Child of Prophecy held her hand tightly.

"Will not."

Yuri said with a firm expression: "Although we cannot change the past, we can change the future——"

"How?" Rosalia asked in disbelief.

The Son of Prophecy said: "The history that we have known cannot be changed, but the history that we have not known can be changed."

"........."

Rosalia covered her mouth: "You mean?"

"As expected of your Highness, have you noticed?"

Yuri smiled mysteriously: "If we are trapped in the spiral of cause and effect forever... then all we have to do is jump out of that "loop."

After deciding what to do, they officially began their time travel.

"The Mirror Temple can only perform time manipulation three times."

In Act 1, Yuri and Rosaria have already reset the timeline using the Mirror Temple.

That is to say, Yuli has two more times left to use.

Yuri will use one of his only two time travels to preach to his past self.

“It’s really troublesome if you think about it carefully…” Yuli scratched his head speechlessly.

Rosalia stroked her cheek and said with a smile: "Don't complain now, my knight."

“Well… since even His Highness has entrusted me with such an important task, there is no way I can refuse.

Then, I'm off."

Yuri came to the prism in the center.

After a large amount of magic power was injected into the mirror, it began to show ripples like lake water.

"Hey... Rosa, after everything is over..." Yuli began to speak hesitantly.

"what happened?"

“No, it’s nothing after all…” Yuli shook his head.

"It's not impossible for me to agree to your relationship with Celeste."

In the boy's surprised eyes, Rosalia showed a charming smile: "It depends on your performance."

Yuli felt his chest warm, put on the headless knight's helmet, and stepped into the mirror.

After only a few seconds, the Child of Prophecy fell out of the mirror.
