To create Honkai Impact 3rd in a world where Kallen exists.

—Just when I thought I understood her, she always discovered more unknown things about me.

At least, she wouldn't spend 500 years on an experiment with no hope of success.

"Given such vastly different external experimental conditions, is it possible to engage in so-called thinking solely based on one person's brain?"

Wilvi was, of course, very interested in this, a smile always playing on her lips, composed and unhurried.

To persist in accomplishing the impossible for 500 years—the other party was even more insane than she imagined. Judging solely from the text in the subtitles…

She was quite certain that the other person was just as crazy as she was.

"Uh, did you guys understand?" Alicia raised an eyebrow as she looked at the two people who were sighing to themselves.

The other person didn't seem to want to talk to her, but of course she wasn't that angry; it was just a girl's little mood.

...

One answer after another surfaced in his mind, arranged, transformed, and combined, forming blueprints and paintings, torn apart and reassembled, reassembled and torn apart again...

In this cyclical process, a hazy phantom gradually takes shape—

"Now, let's imagine a tree, the tree of imaginary numbers."

Suddenly, the sound rang out, without the anxiety and confusion that had been felt from the subtitles. Instead, it returned to calm, like the relief and enjoyment of finding the answer.

"There is a tree whose top is blinding and whose branches and leaves block out the sky."

"Beneath the tree lies a vast sea, its depth unfathomable, its boundaries untouchable."

"In the world, there was only one sea and one tree, and so they began an endless competition."

"The ocean continues to expand and grow, and the giant tree continues to take root and grow, trying to both submerge and absorb the other."

"The tree, nourished by the sea, has endured countless years, branching out countless branches and bearing countless flowers and leaves."

"In this endless process, in some insignificant corner, among some newly sprouting leaf buds—"

"A civilization called humankind was born."

What's going on? Trees and the sea, I don't understand.

[The Sea of ​​Quanta is easy to understand; Seele was in it back then, wasn't she? But what is the Tree of Imaginary Numbers?]

Humanity was born from a leaf, a leaf holds a Bodhi tree? How did this turn into theology?

Clearly, each expansion of the system means the collapse of a group of collapse theorists, but this does not mean that everyone will be affected.

For example, the two PhDs on anti-entropy, and some people who already knew the principles of the world.

"Damn, it actually matches our research results!" Tesla exclaimed, watching the man in the video speak with such confidence.

The theories of quantum mechanics and imaginary numbers are so complex that breakthroughs in anti-entropy have been few and far between. Surprisingly, some of the most fundamental concepts were explained slowly and deliberately by the other party.

For a time, breakthroughs were made in the previously stagnant research.

"...It is indeed commendable, but unfortunately, the game only explains the most refined and basic part, and does not talk about the deeper levels."

Einstein stopped what he was doing and pondered the ideas of quantum mechanics and imaginary numbers, and found that they did indeed coincide.

"But this is also quite remarkable; this statement, in relation to the relationship between the two parties, is...novel yet easy to understand."

"Well... after all, both quantum and imaginary numbers are only vague concepts. The analogy of two forms makes things clear immediately, which is very helpful, at least in terms of popular education."

...

"That's true, it's pretty much the same. However, since we already know about this thing, we should have left it with them as well."

Mebius was not surprised; previous civilizations were aware of these studies and had them recorded in the Void Archives.

However, it seems that he and the other party do not have a good relationship, so it is unknown how much of Otto's ideas came from his own imagination and how much was recorded.

"Hey, hey, hey, you guys didn't tell me this at all."

Alicia was very curious. She always found these fields of quantum mechanics and imaginary numbers confusing, but this time she actually understood them.

"...Alright, you all seem to have figured it out, at least the other party did a good job in summarizing."

Mebius stubbornly insisted,

"No, no, Mebius, did you really tell me anything like this? I have absolutely no recollection of it!"

Alicia waved her hand and said, "Could it be that the other person said it but I didn't understand it at all?"

How could that be? Pretty girls... must be smart, right?

"Tch, obviously it's because you don't understand. What does it have to do with me? That time you kept bothering me, and you fell asleep halfway through the conversation..."

Mebius stopped talking in time, but others still caught on to what he was saying.

"Ahem—excuse me for interrupting you. The knowledge of the Void Treasury naturally includes this part, but... it's chaotic and disordered, making it difficult to summarize."

Vervi coughed twice and added that the Void Treasury stored most of the knowledge of the previous civilization, but that didn't mean it was easy to retrieve it all; its design was not that simple.

"so?"

“He is indeed exceptionally intelligent; 500 years of wisdom allowed him to discover the truth even without experimental equipment,” Velvi nodded in agreement.

“Yes, that’s right, probably about 100 Alicias,” Mebius sarcastically remarked.

"Hey, how could I possibly become a measuring tool?"

...

The Tree of Imaginary Numbers—the moment Otto touched this term, he completed his Eureka.

The chaos suddenly became orderly, and he suddenly saw a winding path extending out of the darkness.

He began to run along the road, and the further he went, the brighter the light in his eyes became.

Unbeknownst to him, he had reached the end of science.

He knew that previous research had reached this point, but he was determined to follow in their footsteps and leap into an even darker, more unseen abyss—

"Imagine this! Imaginary numbers are the starting point of humanity, the beginning of civilization."

"Time flows along the trunk of the tree of imaginary numbers, branching out into infinite worlds like the canopy."

“Every branch is a form of civilization. Every flower and leaf is a reflection of their past and present in the dimension of time.”

"However, the development of the world needs constraints. In the competition with the quantum sea, the direction of branch growth is constantly being filtered and corrected by a mechanism."

"A naturally formed mechanism, a mechanism originating from imaginary numbers, a mechanism of nurturing and nourishing, a mechanism of purification and elimination."

"For humanity, that is the calamity known as Honkai."

"That's right, that's right, humanity can never escape the Honkai."

"Humanity can only move forward, because the tree of imaginary numbers must grow. Otherwise, we will wither away like those failed worlds, becoming just another bubble in the sea of ​​quantum mechanics."

"If humanity wants to achieve lasting peace, it must return to the beginning of civilization, to the realm of the imaginary."

"And the answer I seek must lie within that tree of imaginary numbers—"

...

"This explanation... 'chicken coop head,' what do you think?" Tesla looked at the other person's gloomy face and said sullenly.

"Phew—unfortunately, it matches perfectly, and it makes perfect sense with his previous research."

Einstein pursed his lips and said,

I never expected Otto to be so formidable in scientific research in the game. I thought 500 years would limit his thinking, but his mindset is simply beyond the reach of an entire era.

She also felt immense pressure in this regard; if they were to ensure victory over the Honkai, if the game world could defeat the Honkai,

Clearly, Otto's role must be replaced.

But the better the other party performs, the more pressure they have to shoulder.

"Hmm... What the other party said perfectly explains the strange mechanism of the collapse that occurs with the growth of civilization. Although I'm reluctant to admit it, that despicable man is quite capable."

Tesla said fiercely.

The fastest way to earn someone's admiration is naturally to defeat them in their area of ​​expertise.

Tesla could certainly say that he was good at electromagnetism and mechanics, but wasn't Otto better at and more prominently known for his position as the leader of the chosen one?

...

In the 559th winter of his life, Otto found the path to truth.

He explored the quantum sea, he surveyed the etheric anchor point, he searched for imaginary creations, and he took the enormous key of God into his hands.

He experienced setbacks, he encountered obstacles, he fell into difficulties, he experienced failure, and he gained countless impossibilities.

But Otto doesn't need to know that it's impossible.

Because he made the decision, because it had to be possible—

Otto Apocalypse, to reach the realm of God.

Otto Apocalypse, he seeks to ascend the Tree of Imaginary Numbers.

Then, the two figures appearing within the golden light were clearly engaged in negotiations.

Otto chose Changkong City as the location for the beacon because it required a large amount of Honkai energy to activate.

Three years ago, it left behind a singularity connected to the Tree of Imaginary Numbers. Even though the Third Herrscher is asleep, Honkai energy continues to be released from the singularity.

A few days later, the outbreak will reach its critical point.

The light faded, the barrier dissipated, and Kevin walked out.

And Otto...

"—A toast to the union of destiny and the serpent."

He was in particularly good spirits and in a good mood.

...

"Is this the result Otto reached after 500 years...?"

Karen took a deep breath, closed her eyes, and slowly exhaled.

"It's much more complex than I imagined, with many new terms: imaginary singularity, nurturing, elimination, and the entirely new concept of collapse..."
