He changed Tiwat

He saw the Jade Pavilion in the sky crashing down on the demon god in the sea.

He saw the hundred-foot-high waves on the sea of ​​clouds frozen solid by a single step.

He saw the clear, resonant sound of a dragon's roar from its sheath, drawn before the Guiliyuan Dam.

He saw the bookshelves of "Wanwen Collection House", the gambling table of "Yanshang Tea House", and the wine cabinet of "Angel's Gift"...

He also saw a scene he had never seen before—

The wind flattens countless massive mountains and blows them into the distant sea.

An island that doesn't exist in the world rises from the fog-shrouded sea, resembling a golden apple.

Cecilia flowers swayed gently beside the bard who played the lyre, as if dancing and singing with him.

The ema (votive plaques) stand amidst the cherry blossoms of Narukami Taisha Shrine, with the ema boards gradually increasing in density and then decreasing again.

Inazuma Castle was built brick by brick. The scaffolding for the "Thousand-Handed and Hundred-Eyed God Statue" was erected and then dismantled. Then the statue and the city returned to being bricks and tiles.

A once lush cherry tree gradually shrank, its branches contracted, and it eventually reverted to its seedling state...

In addition, there are even some scenes that look extremely absurd and bizarre—

For example, Wendy, who beat a "lady" to her knees in front of the West Wind Cathedral; Zhongli, the older sister who secretly smelled perfume while dressed in women's clothing; and Gan Yu, the sniper who held a "musket guerrilla" sniper rifle and took long-range shots at Shen He by placing the gun on him...

Countless images magnified and shrunk before his eyes, approaching and receding.

Every scene is constantly flowing and changing, as if it will continue to extend to the end of time.

"...Indeed...this consciousness space is actually a 'Hilbert space'."

This was the conclusion he reached after combining the descriptions of space by the Shadow and the Divine Child, and it was also the reason why he was determined to carry out this "time travel".

He knew he had won his gamble.

Shadow and Divine Child do not possess the knowledge that Earth transmigrators have, so they can only be described as "abstract".

However, Han Fulai possessed the relevant knowledge.

As a liberal arts student, he didn't need to study courses like "functional analysis," and his understanding of "Hilbert space" was limited to the superficial aspects of popular science books. However, the "time tunnel" he was in was indeed very similar to the "Hilbert space" that only existed in the abstract field of mathematics.

Anyone who has been exposed to the concepts of quantum mechanics cannot bypass the concept of "Hilbert space." Hilbert, the mathematician who famously criticized Einstein's mathematics, created "Hilbert space," which is one of the mathematical foundations of quantum mechanics.

In short, "Hilbert space" is a space with "infinite dimensions".

Humans are creatures that live in "three-dimensional space".

This applies to both Earth and the continent of Teyvat.

So, beyond "three-dimensional space," are there "four-dimensional," "five-dimensional," or even higher-dimensional spaces?

Mathematically speaking, it exists; mathematicians discovered the patterns that constitute dimensions long ago when studying geometry.

If you move a zero-dimensional "point" along a certain direction, a one-dimensional "line" will appear; if you move this line segment perpendicularly, a square composed of "lines" will appear, which is a two-dimensional "plane"; if you move this two-dimensional "plane" perpendicularly, a three-dimensional "solid" will appear...

The three-dimensional world that humans see is actually made up of overlapping two-dimensional planes.

After summarizing the patterns, mathematicians discovered that:

A zero-dimensional point contains only one zero-dimensional element (point);

A one-dimensional line segment contains one one-dimensional element (the line segment) and two zero-dimensional elements (the endpoints).

A two-dimensional square contains one two-dimensional element (plane), four one-dimensional elements (edges), and four zero-dimensional elements (vertices).

A three-dimensional cube contains 1 three-dimensional element (three-dimensional solid), 6 two-dimensional elements (faces), 12 one-dimensional elements (edges), and 8 zero-dimensional elements (vertices).

By analogy, a one-dimensional world is composed of zero-dimensional "points", a two-dimensional world is composed of one-dimensional "lines", a three-dimensional world is composed of two-dimensional "planes", and a four-dimensional world should be composed of three-dimensional solids of one lower dimension.

Mathematicians imagine a four-dimensional "hypercube" containing one four-dimensional element (four-dimensional hypercube), eight three-dimensional elements, 24 two-dimensional elements (faces), 32 one-dimensional elements (edges), and 16 zero-dimensional elements (vertices).

The five-dimensional "hypercube" is composed of individual four-dimensional "hypercubes"...

In short, regardless of the number of dimensions, it's all about "stacking boxes" upwards, just like in those fantasy novels. After becoming "invincible under heaven," "enemies will come from the sky"...

"Hilbert space" is precisely such a culmination of stacked boxes with infinite dimensions, and it interprets the "many-worlds theory" in quantum mechanics.

Since the three-dimensional world can be viewed as being composed of countless two-dimensional planes, our universe could very well be a "Hilbert space" with very high, or even infinite, dimensions.

The so-called "parallel worlds" are projections of the lower-dimensional worlds that make up the "Hilbert space".

There is a Chinese poem that says, "Viewed horizontally, it's a ridge; viewed from the side, it's a peak," which describes the principle of this "projection."

For example, if there is a cone in space, its projection below itself will be a circle, while its projection to the side will be a triangle.

If Han Fulai were a "paper man" living in a two-dimensional world, he would never see the cone in higher dimensions, but only the triangle or circle projected onto the plane of that cone in the two-dimensional world.

In quantum mechanics terms, a cone in the three-dimensional world is actually a "superposition" of a triangle and a circle in the two-dimensional world. It is a real world created by superimposing two parallel worlds, and the "observers" in each parallel world can only see the "projection" of the real world.

Similarly, "Schrödinger's cat" is also in such a superposition state. The real cat exists in a "Hilbert space" that is higher than three dimensions. Its essence is both dead and alive, but the "observers" in the lower-dimensional world can only see the "projection" of the cat as either dead or alive, which is just one side of the real world.

In the three-dimensional world, time is linear and irreversible, like a river that can only flow towards the sea. But in this "time tunnel" where time can move in any direction, time also becomes a dimension of space.

The lines that Han Fulai saw were actually projections of "timelines" in space; they were extensions of space in different time directions.

Those memories he had seen and those he hadn't seen before, those seemingly absurd and bizarre scenes, were all "parallel worlds" of this Teyvat world.

If Wendy doesn't hold back, he should have no problem punching the "ladies," and Zhongli could certainly transform into a woman if he wanted to. And it's not impossible that Gan Yu, who is proficient in all kinds of martial arts, could use "Winter Iaijutsu"...

Then, there should also exist a world he desires—a world with a "happy ending".

In the "timeline" he was on before, Inazuma had actually entered a "bad end" branch.

Due to the "dark calamity" five hundred years ago, Inazuma's ley lines were already "terminally ill," and the divine child chose to sacrifice himself to absorb the filth of the ley lines in order to prolong Inazuma's life.

Although killing the divine child could temporarily alleviate the calamity, Inazuma's ultimate fate would still be irreversible destruction.

Han Fulai did not want to see this outcome.

What he needs to do is find the one and only world in this "Hilbert Space" with countless parallel world branches, a world that can save both the Divine Child and Inazuma.

He made his own choice.

After the light faded, Han Fulai opened his eyes.

He appeared in front of the sacred cherry tree once again.

But unlike before, this divine cherry tree was just an ordinary-looking cherry tree, not the fox-shaped one he had seen before.

Furthermore, the divine child in his arms had also changed its appearance.

—The red and white shrine maiden outfit she was wearing disappeared, replaced by a white kimono.

In Inatsume, it is called "Shiromuku," and it is a wedding dress worn by women when they get married.

Chapter 249 Dust Covers Face, Temples Turn White [4k]

The goddess had regained consciousness and was looking up at the man who was holding her.

Their eyes met for a moment before Han Fulai looked away.

If the image of a shrine maiden in the past was one of mystery and cunning, then a shrine maiden dressed in a "white kimono" evokes a sense of "holiness."

The pure white silk, like moonlight solidified, flowed down her slender figure.

Her smooth, long pink hair was neatly tied up with a silver paper hair tie, styled into the traditional "Takashimada Bun" of Inazuma, looking incredibly elegant and dignified. Two strands of hair that broke free from their restraints fell down her neck, lightly brushing against the snow-white robe embroidered with cherry blossoms at the collar with her breath, the slightly curled ends of her hair resembling the curled tail of a young fox, tickling her in the wind.

Those fox-like eyes, which usually held a playful air, were now tinged with a faint red at the corners. The originally cunning, upturned corners of the eyes were softened by the vermilion, giving them a touch of girlish shyness.

No man could resist being looked at like that by a goddess dressed in a "wedding dress".

In particular, she is still clinging tightly to him.

A few seconds too late, Han Fulai finally realized that it seemed unnecessary to hold Shenzi any longer...

He quickly released his grip, somewhat embarrassed, and apologized to the divine child: "I'm sorry, I didn't mean to offend you... The 'Seed of Time' didn't cover a wide enough area, so I had to..."

The shrine maiden tilted her head slightly, a fox-like smile playing on her lips: "Isn't it normal for a 'god' to embrace his 'fellowship'? Oh, could it be that 'God's Lord' has other intentions?"

Hearing that familiar teasing tone, Han Fulai couldn't help but chuckle: "...It's definitely Lord Gongsi himself. It seems that even if he changes his clothes, Lord Gongsi is still the same Lord Gongsi."

After discovering the changes in the Divine Child, he was worried that she might have been affected by something during her time travel... But now it seems that the Divine Child is still the same Divine Child.

The princess lifted the hem of her kimono and twirled around a few times as if showing off.

When the wide sleeves of the robe billowed in the wind, the shimenawa (a type of stringed cord) tied around the wrists was faintly visible, with tiny golden bells hanging from each end of the cords—these are the "kagura bells" used in the Kagura dance.

As her wooden clogs rolled over the fallen cherry blossoms, the silver threads flowing from her hem rippled, as if each step she took was shattering the surface of the river of time.

Han Fulai noticed that Shen Zihaobai also had bells tied to his ankles.

Her every movement was accompanied by the tinkling of bells, like a walking symphony.

"'I declare to the White Star the reason for the suppression of the soul; grant me permission to offer my prayers and guide the lamps on the way home. I am filled with awe and fear for the divine might..." The priestess softly recited, "This outfit is the ceremonial attire worn by the priest of the Great Shrine when performing a dance before the deity, and also... the ritual attire worn by the teacher of the Rei-gyu Temple."

"Five hundred years ago, I wore this 'white kimono' to exorcise the lingering soul of Master Saigu."

The "Shiromuku" is the traditional wedding dress worn by women in Inatsuma, symbolizing that the woman is pure and flawless, like a blank sheet of paper—only her husband can give her a new color.

In the past century, due to the struggles among the three magistrates and the impact of the "Raiden Goden" incident, the power of the shrine magistrates has declined to some extent. However, in ancient times, the shrine magistrates shouldered the responsibility of being the "witnesses" for the entire Inazuma clan.

In the past, high-ranking samurai and noble families would typically hold their weddings at Narukami Taisha Shrine for a "divine wedding ceremony," where the statue of Narukami would witness their vows of eternal love and receive his blessings. Having the shrine's chief priest officiate at the wedding ceremony was a source of considerable prestige.

The ceremonial dress used in the "Shinsenjiro wedding ceremony" is the "Shiromuku".

The white of the "Shiromuku" (white kimono), like the white of the shrine maiden's outfit, symbolizes a woman's purity and also represents a pure and unblemished heart in serving the gods.

The reason it became a wedding dress is actually the same as the reason why Inatsumi people admired purple—because it represents the clothing of that Hakushitsai-ō.

Its whiteness is actually the "white" in "Baichen," symbolizing the blessing bestowed by Baichen Zhaiwang.

The goddess wore this white kimono during the "Great Purification of the Divine Cherry Blossom" five hundred years ago, not to marry someone, but to tell her teacher that she had taken over the duties of Hakushō-ō.

This is a tribute from the new generation of Bai Chenzhai Wang to the previous generation of Bai Chenzhai Wang.

Although the goddess didn't show it, Han Fulai knew she was feeling sad.

He didn't mention the "white kimono" again, but took a few steps forward and steered the conversation toward the Divine Cherry Tree: "We should have successfully traveled to the moment of the second 'Great Purification of Divine Cherry Tree,' but the Divine Cherry Tree seems to have changed as well?"

The goddess smiled gently: "The cherry blossom tree is planted on my land, so of course it has to be pruned according to my tastes. You also think the cherry blossom tree I pruned looks better, right?"

"Yes, yes..." Han Fulai reluctantly agreed.

The "pruning" that the divine child referred to was certainly not as simple as cutting branches and modifying the shape. The reason why the divine cherry tree turned into the shape of a fox five hundred years later was because the soul of a certain pink-haired fox resided in the tree.

Looking back now, the reason why the Divine Child was able to become the youngest "Heavenly Fox" in Inazuma history at the "age" of five hundred years is probably because she merged with the Divine Cherry Tree.

To gain power, one must naturally pay a price.

The price paid by the divine child was considerable.

The good news is that they have now successfully traveled back to the time before the divine child paid the price. This "normal" divine cherry tree represents the time when the divine child's soul has not yet merged with the divine cherry tree.

In other words, she is not yet "terminally ill".

Of course, this doesn't mean that if you travel back to this point in time, the god's "illness" will be cured.

The soul of the divine child has merged with the divine cherry tree and is currently being corrupted and eroded by the evil spirits in the earth's veins. The divine child who previously made a contract with him, as well as the divine child he took with him through time, are both the "souls" of the divine child from five hundred years in the future.

Specifically, he is "physically present," while the divine child is "spiritually present."

This is also why the goddess wore this "white kimono".

It wasn't that she underwent some kind of "one-click outfit change" during the time travel; rather, it was that the soul of the divine child from 500 years in the future traveled into her body from 500 years in the past.

If the divine child hadn't "soul-transmigrated," he probably would have been struck by lightning just now, right? After all, from the perspective of the divine child five hundred years ago, it was a strange man who suddenly appeared and hugged him...

Since this divine child could recognize him, it meant that the time travel had been successful. They had indeed traveled back to the time of the second "Great Purification of Divine Cherry Blossoms" five hundred years ago. The "normal" divine cherry tree in front of them, and the divine child wearing a "wedding dress," were the best proof.

As the saying goes, "a good start is half the battle," and the first step of "crossing over" has been achieved; it's time to move on to the second step.

"In short, what we need to do next is find the outrageous films of this era. You should know where she is now, right?"

As Han Fulai asked the questions, he subtly raised his hand and rubbed his temples.

The headache caused by the whispers of the evil star was getting worse.

Previously, he "passively traveled through time," and the energy he needed was provided by others. This time, however, he "actively traveled through time," and the energy he consumed was borne entirely by himself.

Even though he was already a demigod, and had the blessing of the "Seed of Time," the power he expended almost left him exhausted.

In terms of sheer pain, the burden he is currently enduring has surpassed that he experienced with Ye Lan in the "Taiwei Instrument Plate" space.

“I think you’d better rest for a while… Do you know what kind of state you’re in right now?” The priestess’s voice was full of worry.

"Me? What's wrong with me?" Han Fulai asked, slightly puzzled, while scanning his body—he was neither missing an arm nor a leg, and looked no different from usual.

The priest did not answer, but silently took out a small mirror from his sleeve and held it in front of him.
