People are in Type-Moon, but they practice science

Chapter 295: The Long River of Destiny, Records of Destiny

Time travel is undoubtedly the realm of magic.

It is also the realm of the second law, and also includes the tampering of records, the rewriting of phenomena, etc. This is the operation of the parallel world.

Today, when the association applies the results of the Second Law, the source is only the data drawings of the gem sword, so it appears more like space technology and cannot present the complete Second Law.

But there is another kind of magic that involves the manipulation of time, and that is the fifth method.

Qingzi once described the fifth method of time manipulation to him, which was actually time reversal. Time travel, after all, was just entering any time point you wanted within the world's "progress bar", but the progress bar was always moving forward and would not be affected; while time reversal completely broke the arrow of time, forcibly reversed the world's progress bar, and broke the second law of thermodynamics.

In fact, in the field of science, "time" is always a vague unit, and its expression and distinction between the past and the future are all supported by other related quantities. If we have to choose an arrow to describe the development of everything, it should be entropy.

The increase of entropy, that is, the increase of disorder in the universe, indirectly indicates the flow of time. Qingzi's "Retrograde Canal: Genesis Light Year" is a subversion of this cosmic law.

However, Qingzi himself is not there, so there is no hope of using magic. Qin Xuan needs to use a method that can replace magic and achieve a similar effect to jump over.

"Hmm, I feel dizzy after listening to this." This is Illya.

Chloe could understand it. "It's not about going back to the past, but about changing the past?"

"——Anyway, that's the principle. If we don't go back to the past and change something, Emiya Shirou's soul won't come back, and that black hole will eventually destroy the planet, right? Miss Tanaka."

After Qin Xuan described his thoughts, he continued to ask questions to the incarnation of Gaia.

"...Yes." Tanaka seemed to have lost his innocent attitude and said calmly, "If there is any possibility of change, it is only the past."

"Hey hey - Miss Tanaka, your character! Your character is not like this!" Illya complained. Isn't this switch too abrupt?

“Ah? Is this what your character is like? Am I that amazing? Hahahaha—”

"I'm not complimenting you..."

Tanaka laughed in a mysterious way, which made Illya unable to understand her train of thought. At this time, Tanaka seemed to be acting silly again, and she didn't understand what personality was... No, Gaia didn't have the complete personality from the human perspective.

"Okay, don't interrupt." Qin Xuan's idea still focused on Tanaka. "Tanaka, you didn't recover your memory before, did you? How much do you remember now?"

Since we were created to avoid destruction, we must not fail at the critical moment.

"Well, I remember now. I am the restraining force that the planet generates to save itself. I am the incarnation of Gaia."

"… Restraint?" Illya and the other two had heard of this term in magic class. "——Huh, it's actually restraint!?"

"Yes, in order to save this ending, I asked for help from you, the people of the origin world. In order to help you come here as soon as possible, I even used some of my power."

Tanaka was talking about the fact that when Qin Xuan first started exploring the Miyu world, the operation of the spirit particle collector suddenly accelerated.

"But now it seems that there is only one step left to the end of destruction." Miyu said after thinking for a while.

That's right, black holes have begun to devour planets.

If we float up to the real space again, we might see the planet being completely absorbed.

"That's not right," Tanaka denied. "The current results have not been confirmed by 'observation'. It's like suddenly stopping at the last second before the end. As long as we don't confirm the complete end of the planet in subjective time, the 'end' will always be in a state of not coming."

"The ending hasn't been confirmed yet?"

"That's right. One of the reasons is the place we are in, the dimensional gap," Qin Xuan added. This is also one of the conditions for him to be sure of traveling through time. "After all, this is a field of chaotic space-time, a gap outside of each intrinsic world, an area of ​​unknown reality. As long as you are in this place, time-space travel is theoretically possible."

However, they are now sailing aimlessly with a completely random direction. This situation should be more like 'time-space drifting'. Not to mention stable time travel, the chances of searching for the submarine on Ziyuan's side that may also be stuck in the gap are extremely small.

To get back to the point, the possibility of this reversal of the ending is just like Chaldea's 1.0 human salvation. Although the outside world was burned and Goetia's retrograde canal was completed, as long as Chaldea, which is outside the timeline, defeats Goetia, which has not completed the retrograde canal, it can forcibly reach the undestroyed pan-human history before Goetia reshapes the planet.

This is no longer the simple timeline that is commonly understood, that is, the issue of the horizontal axis of time. It involves the issue of the vertical axis beyond this.

"Yes, yes, that's right... Well, it doesn't matter if you can't understand it, Illya." Seeing Illya thinking hard, Tanaka patted Illya's head to comfort her.

"Also, to go back to the past, there must be a guide, or something that can continuously prove the existence of the floating coordinates," Qin Xuan continued to explain. This is not Chaldea's spirit particle transfer, but more like an imaginary number submarine. If they want to travel through time, there must be an existence that can provide them with direction on the timeline.

"Ding, ding, ding - that's me," Miss Tanaka said, patting her chest.

"——The existence that can continuously provide proof of time is the Star Canal!"

In short, a journey of salvation, a journey with no chance of turning back, began.

--------

As if to block out the light, time stood still.

A deep, long, and boundless darkness that is completely different from the dimensional rift.

But in all this still darkness, there is also a flowing meaning (record), on the endless canal of stars.

This is the river of planetary records, the long river of time. Complex stars dot the darkness. They are the tracks of birth and death and the rotation of all living things on Earth. They are the inscriptions of fate stars that have continued from ancient times to the present, and the observation records of all life paths. The fate of people, like the stars, their immortal soul elements are all recorded in the starry light.

"What a nice view……"

"Ms. Tanaka looked unreliable, but I didn't expect her to be so amazing."

Illya and Chloe couldn't help but look out the portholes of the ship, while Miyu stood aside and admired silently.

Tanaka, who was in charge of the guide, put his hands on his hips and smiled, while Qin Xuan was calculating something on the side.

Chapter 296 Six Thousand Years of Despair

Star inscriptions, records of star destiny, represent all things in the world. Since ancient times, humans have had the habit of associating stars with personal destiny, family and national politics, and the changes of events.

For example, the ancient prophecy and divination in China contains a lot of astronomical content, such as "white rainbow piercing the sun", "Mars guarding the heart", "stars divided into wings and pegs", "touching the calendar and looking up and down", etc. In Western mythology, there are also conventions of connecting gods with stars, or directly promoting heroes and other people who have left merits into constellations.

After all, in the Age of Gods, contacting the starry sky and borrowing the power of the stars was a common behavior. Astronomy was not a declining discipline like the modern one that observes the stars and uses weak astrology plus some theology, but a real discipline that uses the stars in the universe as its objects and performs various miraculous powers.

False astrology: observing the movement of celestial bodies, fortune-telling, and superstitious talk.

Real astrology: meteor showers, supermassive black holes, grand crosses. (crossed out)

What Qin Xuan was recording and calculating were the various star inscriptions that could be observed on the Star Canal.

This is a great opportunity. In modern times, except for magicians, there is almost no one and no conditions that can observe the magnificent scenery of the "Star Canal".

Although to a child like Illya, these are just beautiful stars gathered into numerous constellations, a rare beauty to see in this lifetime, but in Qin Xuan's view, the star inscriptions and destinies of these living beings reflect the evolution of a series of historical trends from the dawn of the Age of Gods, the alternation of the first and second Ages of Gods, to the succession of humans and gods, and the establishment of human principles...

To be precise, it should be the other way around. After all, they are heading towards the past, sailing upstream on the river of destiny.

However... the workload is really huge. Just recording is not enough, analysis is also required. If possible, Qin Xuan wants to know the mechanism of the human beings who became heroes/heroic spirits in the past history, after experiencing their own legendary deeds and sublimating into heroes, and obtaining skills/treasures. This clearer record should be able to bring new progress to intelligence agencies/armament technology...

By the way, in the Age of Gods, there are records of people ascending to the throne of God from human bodies, and the process of obtaining divinity and building a system of gods through people's faith is also worth recording. In addition, there is the "torrent of the times" where the fate of all living beings converges, and the relationship between this concept and the foundation of human nature.

Human principles are a very important concept, and they are also a mechanism that Qin Xuan rarely recognizes and needs to refer to and utilize. In the divine principles before human principles, although the gods exist together with humans, humans are still like grass, and the tide of fate is controlled by the gods. In the human era, the direction of the times has officially shifted to the masses. The gods have retired, and heroes have ascended to become the shadow of human history. History is created by the masses. And in the foreseeable future, ancient existences will become increasingly rare and mysteriously decline, evolving into a route similar to the people's view of history...

Well, let’s record as much as possible first, and analyze and utilize it later.

"Hey, Ms. Tanaka, there are too many stars," Illya looked at them for a long time and felt a little dazzled. The Star Canal was so wide and boundless that she could hardly tell the specific direction. "Where are we going now?"

I heard that people have used the stars in the sky as guides for navigation since ancient times. The stars here are right in front of us, so they should use a similar method, right?

"Hi, yes, we are sailing along the trajectory of a certain constellation," Tanaka said, having changed into a uniform at some point, "Also, Illya, please call me Navigator Tanaka!"

"Ahh, navigator?"

"Yes, it was appointed by this captain (Qin Xuan)!" There seemed to be stars in Tanaka's eyes. This was another human world word she had learned in her life.

"Ms. Tanaka is capable of such a high-tech position?" Seeing her so excited, Illya didn't want to spoil her fun. She felt that she had not yet gotten over her first impression of "silly Tanaka".

"Okay, don't be distracted," Tanaka indicated that the voyage was about to enter the next stage. "The route we are going to take (Star Inscription) is Pandora's record, the star trajectory that extends from ancient times to the present."

That’s right, to unlock the secret of Pandora’s Box, Pandora’s records are the most direct answer.

Hearing this, the little girls stared closely at the constellation formed by the ever-extending starlight. That was where Pandora's records were. Even that one line had numerous stars, and they were gradually approaching one of the bright spots.

That is... a fragment of Pandora's life. As she got closer, the light and shadow changed, and under the stars, there were hidden past events.

——The castle that was still magnificent yet old…a room that was so large that it seemed empty…somewhere in the location of Ainsworth’s workshop ten years ago.

At that time, Julian, the head of the Ainsworth during the Fifth War, was still a kid with poor skills in substitution magic.

Julian is not the eldest son, nor does he have any magic talent. He can't even use the basics of substitution magic, shape substitution. But at that time, he had a sister, Emilia (Pandora), who was very kind to him. Julian tried again and again to use the fork to substitute into other shapes, but failed again and again, and tried again and again.

At that time, Julian said to Pandora: "I will grow with my own strength. Just wait and see. From now on, I will always..."

——However, Pandora committed suicide.

Julian was planning to show off the fork he had successfully replaced, but he saw Pandora commit suicide.

"Why is this happening... the bleeding won't stop... Oh, right," young Julian panicked after seeing his sister's "corpse", "Oh, right - I must tell Dad as soon as possible!"

"What's wrong? Julian, what are you arguing about?"

Hearing this, Julian turned around and saw his father... No, that was - his "father" who had been replaced with Darius' appearance.

"Ah, I'm your father Darius." Darius said these creepy words without any emotion. Then, he looked at Pandora on the ground leisurely, without any movement, "It's been a long time since you had an attack, this kind of situation..."

“——!” Julian didn’t quite understand. “What are you talking about… You need to get treatment quickly——”

"That's what you're talking about. It's impossible to die like this. I told you about immortality."

Darius revealed Pandora's secret, "It's only causing her pain, but she keeps committing suicide. Oh, is this thing stuck in her neck... a fork from a failed replacement?"

He picked up Pandora's "suicide tool" and said, "So that's how it is, Julian. You are really cruel. You - made a promise for the future, right?"

"What……"

"You seem to have made a declaration about your future growth. Really, for her (Pandora), who can neither grow nor die, and who has been stagnant for more than six thousand years, the future is just an increasingly hopeless existence."

Chapter 297: Hypothesis of Creation of Spirit, Spirit and Material Celestial Bodies

"No, that's not it... I just..."

Julian couldn't accept that he was the one who caused his sister's suicide.

“——Hmm…”

Pandora, lying in a pool of blood, moved.

"elder sister……!?"

Then, Pandora tried to hold up her body, her face was mixed with tears and blood, "I want to die so much... cough, but I can't... please, just... kill me."

"Ah... I promise, I will find a way to kill my sister one day." Julian didn't want to agree in his heart. How could he bear to let his sister die...

"Get out of the way! Julian!"

Darius simply pushed him away.

“Ouch…!” Julian was pushed to the ground and fell. When he got up, he saw Darius holding Pandora’s neck and lifting her up. “Stop! What are you doing to your sister!?”

"——I am just treating you. The physical wound will heal if left alone, but the mental burden will not be relieved."

Suddenly, Darius let go of Pandora.

Pandora coughed twice and suddenly asked, "Hey, Darius, can you... still hear the voice of God?"

"Heh... You're still saying this now." Unlike Julian who looked confused, Darius knew exactly what Pandora was trying to say. "Have you really reached your limit?"

As he said this, he tapped Pandora's forehead with his finger.

"Poof...!" As if the pain doubled, Pandora suddenly bent down and spat out a stream of black muddy water.

"Even if the body is immortal, the spirit will be tired, not to mention that her heart is already broken, how pitiful," Darius said pitifully, but his expression was cruel, "So, spit out all your spirit. All the degradation is caused by your immature intelligence. It's distressing, right? It's desperate, right? Release all your accumulated evils... and turn back into a child."

Crash.

The muddy water gradually increased and spread. At the same time, Pandora's figure gradually shrank and turned into a little girl with the appearance of a young child, who was exactly the same as Erica. No, that was Erica later.

"Okay, this is your sister, Julian." As expected, Darius smiled nonchalantly, "How did the name come about before? Oh, it should be the name of a flower...ah, let's call her Erica."

Ignoring Julian's pain and confusion when he accepted all this, Darius skillfully manipulated the mud and water transformed from Pandora's spiritual memory. Then the mud and water automatically rose up and were slowly absorbed by the box in Darius' hand... Pandora's Box.

The screen ends.

--------

"Is this really the past of Erica? And that Darius is too much."

Illya had only met and chatted with Erica before. Although she knew that Erica was Pandora, she never expected the process to be like this.

"Erica... has become like that again and again... That's why she has that abnormal naivety." Miyu's mood was very complicated. In the past, Erica always hoped that Miyu would be her friend, but Miyu always felt that Erica's ideas were not normal. It seemed that it was caused by repeated memory erasure.

"Wait."

After Qin Xuan finished watching the video, he stood up and everyone focused their attention on him. "After watching the video just now, an important conclusion has been confirmed."
