And... most importantly, what if the original owner still existed in this world...
A trace of greed flashed through Otto's eyes.
Nothing was beyond being exploited, was it?
—But what if this world contained only one Otto?
Then Kallen would only be useful as a fighter—hmm, did the Saintess from five hundred years ago really possess the strength of an S-rank Valkyrie?
Hard to say. After all, in Kallen's two well-known failed battles where she had been fully prepared, her opponents had both been absurdly powerful.
Cloud Ink Dan Heart Fu Hua could suppress every enemy in the world even today.
The Herrscher of Corruption of the Previous Civilization had fired nuclear weapons while under siege from Fusion Warriors like Kevin and Elysia, devastating the Previous Civilization's infrastructure.
As for how strong Kallen herself was...
Historical records could not prove anything at all.
After all, the one who wrote history was a deranged Kallen fanatic.
Oh, perhaps he could use her to obtain a Divine Key.
Otto narrowed his eyes.
For now, whether he was pretending to be a devoted widower to win the Valkyries' sympathy or negotiating with the original owner and his supporters, Kallen could not be allowed to remain alive.
Once he wanted to give the original owner an explanation, he could summon her back.
Then... whom should he choose?
Otto said nothing, silently outlining the details of his plan in his mind.
Anchor point: ?
Arrival time: ? year
Duration: ? years (Note: with the current abilities of this book, please do not exceed a time span of twenty years.)
Participation time: twenty days (a temporary mandatory rule)
(The time fast-forwarded through the evolution of the Book of XX was the duration, while the time one could personally descend into and alter was the participation time.)
(During the duration, all of your actions must either continue what was done during the participation time or be no different from the original history.)
(During the participation time, you may not move more than one hundred meters away from the anchor point.)
"Mm, let's begin like this..."
Otto closed his eyes and used his thoughts to sketch the settings for time travel into the Book of XX.
Anchor point: Cecilia Schariac
Arrival time: 1985
Duration: sixteen years
Personally available participation time: twenty days
He had many reasons for choosing Cecilia. It was not merely because he coveted her body—otherwise, why not flirt with Durandal?
Kiana was not even up for discussion. He was a dad fan, and going after Kiana would be a crime.
He certainly would not touch either mother or daughter. The dimensional barrier would collapse.
Otto's reasons for choosing her were actually very simple.
Ever since he took power, the Schariac family had produced almost no Saintesses who betrayed him.
Even if they did not agree with Otto's methods, they would still do their best to meet his demands.
Furthermore, Cecilia herself was a major core of the plot.
If she stood by the transmigrated Otto's side, then neither Durandal nor Kiana could possibly attack him.
Her loyalty alone guaranteed the protection of at least Cecilia, Durandal, Rita, Kiana, and Raiden Mei.
—This meant absolute command. Cecilia could fully direct them, and there would never be any resistance. They would not only obey willingly, but the pressure of seniority would ensure that every one of their important decisions would be discussed with her.
As for Siegfried... heh. He was the kind of man who brought his biological daughter, still only a few years old, to rob a laboratory at Schicksal Headquarters. Otto preferred to keep his distance from him, and even needed to find a way to sever his relationship with her, lest his recklessness force Cecilia into defiance.
All in all, three S-rank Valkyries and two Herrschers. If this lineup took another bite out of Kevin in Sea Abyss City... beneath the Finality, wouldn't I be invincible?!
Besides, bringing her back... would allow every difference between Otto and his past self to be attributed to the changes brought by the Saintess's return.
After all, she was someone from many years ago. No one truly knew what kind of relationship he and she had shared. Even Amber's memories from that time would surely be vague.
So long as he won Cecilia over, every problem caused by transmigration could be resolved in an instant.
And obtaining Cecilia's loyalty...
The name Otto Apocalypse already had maximum favorability with every Schariac.
The reason he wanted to simulate 1985 rather than directly save her during the Second Honkai was merely to familiarize himself with Cecilia, his ability to alter the past, and the feeling of acting as Bishop along the timeline.
"Begin," Otto muttered inwardly.
Evolution began. Red text marked forbidden points in time, while green text marked flexible points in time.
The last sentence remained for ten seconds. Then, the settings he had written into the ancient tome gradually faded, replaced by a new line of text.
In 1985, you used Cecilia as an experimental subject and created Schariac Holy Blood with an exceptionally high completion rate. All the blood within Cecilia's body was also converted into Holy Blood capable of instantly eliminating Honkai Energy.
But because of this, in order to protect this important Schicksal technology, you imprisoned Cecilia Schariac within Schicksal Headquarters.
Quite a lot of this was green text...
Otto thought for a moment, then spoke.
"Book of XX, remain in 1985 for one day."
The book temporarily stopped producing text, and a force connected with his mind.
He closed his eyes. The next second, he appeared outside a Simulation Training Room.
Inside the Simulation Training Room was a girl with exquisite, beautiful features. Her long hair cascaded behind her like a silver moon falling from the heavens, radiating a charm that could captivate anyone, male or female.
She wore a pure-black battle suit and held an enormous lance in her pale little hand, lightly hurling it toward the exposed abdomen of a Honkai Beast.
The data-simulated Honkai Beast swiftly dissolved into scattered streams of data, leaving only Black Abyss White Flower embedded in the ground.
"Cecilia Schariac."
Otto called her name softly, deliberately sighed in a profound manner, then revealed a gentle smile.
"Amber."
"I am here, Lord Bishop."
The girl he feared most stood behind him, yet under the Book of XX's protection, Otto did not need to worry about arousing her suspicions.
"Can big data analyze which country and place Cecilia most wishes to visit right now?"
"..."
Let's test the limits again.jpg
What Is Kallen Fantasy? A Game I Don't Know
You're using big data to analyze that?!
Amber did not know how to respond, but quickly adjusted her mindset. She tapped her tablet a few times and answered, "The results can be analyzed immediately, Lord Bishop."
"Mm." Otto nodded. "Once the analysis is complete, hire several professional travel planners to design a one-day itinerary for that location. The kind for two people."
"Bishop, this..."
With things put so plainly, how could Amber not know what was about to happen?
The Bishop was taking Schicksal's Saintess... on a trip?
What kind of move was that?
"Cecilia's Holy Blood deserves at least one day of relaxation every year," Otto answered as he watched Cecilia train. "Deduct the funds from Kallen Fantasy."
Amber: ???
What? Kallen Fantasy?!
That was Kallen Fantasy... the game you had embezzled public funds to develop!
Cecilia's Holy Blood... was actually this important to you?
Otto saw the shock in Amber's eyes beneath her goggles. The corners of his eyes curved upward, but his pupils remained calm.
He had done this on purpose...
"Understood, Lord Bishop."
Amber had doubts, but she did not voice them. She turned and left.
"Build up some feelings, make things easier to handle later."
Otto leaned against the wall, enjoying the visual feast Cecilia provided as she fought.
According to big data, you spent a day with Cecilia at a certain amusement park. However, the travel planners seemed to have misunderstood something. For some reason, the people around you and Cecilia were always couples, making Cecilia blush furiously.
So, to make Cecilia less shy, you used your authority to drive every couple out of the park.
"..."
How wonderful. This damned power.
During the final half hour, you rode the Ferris Wheel.
Otto opened his eyes and met Cecilia's gaze. The girl was covered in fragrant sweat, her lips involuntarily curling upward as though she had cast off some burden.
"Cecilia Schariac."
"Mm... yes, I'm here, Lord Bishop."
The girl first let out a confused syllable, then suddenly startled and straightened herself before answering.
"From now on, every year, you may choose one day for me to accompany you in doing anything you wish."
He slightly raised his head, looking down upon everything beneath the Ferris Wheel.
"I, Otto Apocalypse, grant you authority equal to the Bishop's at this moment—from a certain perspective, at this very instant, in the human world, you shall be capable of anything."
Those extremely chuunibyou yet not remotely exaggerated words unsurprisingly earned him the girl's sparkling eyes. "Thank you, Lord Bishop!"
"Mm. Oh, Cecilia, when we are out traveling, call me Brother."
"Okay, Brother."
On every day she wanted in the years that followed, you took Cecilia anywhere in the world she wished to go.
She gradually became livelier before you, and her words grew much more intimate.
"Brother... why don't you bring Theresa along to play?"
"Because, you see, I refused your request to go out so sternly in front of Theresa... ahem, you understand the rest."
"Oh, it's a matter of pri—"
"Cecilia!"
"Wah, Brother, I was wrong! I don't want to eat so much..."
You really were wrong, Otto answered coldly in his heart.
I'm raising her favorability. How could I possibly let someone else interfere?
He gently stroked the forehead of the girl acting spoiled, and what little conscience he had dissolved at the touch of her soft skin.
Cecilia still respected you, but sometimes revealed the mannerisms of a young girl.
She even surpassed your first-place score in Kallen Fantasy right in front of you.
Before you continue
