He changed Tiwat

Because behind Raiden are Inazuma's people, and also Kage.

Now, it's her turn.

She wants to use this "Dream One Heart" to change the history of Inazuma once again, allowing Inazuma, who has suffered from the "dark calamity," to be reborn like a phoenix from the ashes.

—The moment Ying grasped the true meaning of "one heart, one dream," a ray of light shone from the blade of the long sword, like moonlight guiding the lost in the endless night.

"One Dream, One Heart" was the first response to Ying's feelings.

Ying held the "Dream Together" in her hand, feeling the familiar warmth it conveyed to her, as if she were touching her sister's warm palm once again.

As the light illuminated the barbed markings on the hilt of the sword, Han Fulai smiled with satisfaction.

His efforts were ultimately not in vain.

He successfully gave Shadow the "will" to change the world.

More importantly, the fact that "Dream One" could be awakened means that his previous theories are completely valid and that "delayed choice quantum erasure" is feasible—he may have already touched upon the essence of the world's "fate system".

"Shadow, we have one last thing to do: to completely awaken 'Dream One Heart'."

"Besides this sword, His Highness should have left you something else."

"There's one more thing...?" Ying looked at him with some confusion.

Han Fulai's ability to help her awaken the power of "Dream One Heart" already surprised her greatly, but he seemed to know even more.

This "general's retainer" from five hundred years in the future, despite never having met Raiden Shin, seems to understand Shin better than her own sister...

The problem is... she doesn't remember her sister leaving anything else behind.

"That is the key item that possesses 'power beyond the world,' and also the authority that allows the 'Seven Rulers of the Mortal Realm' to connect with the ley lines—"

Han Fulai then uttered the key word: "—'The Heart of God'."

On the nameless island in Mondstadt, Wendy once revealed to him the nature of the "Heart of God":

"It is the remains of the 'Third Advent'."

"The Third Adventor possessed the power to harmonize the seven elements, transforming them into 'light.' The First and Second Adventors joined forces to create the 'Heart of God' using his remains, establishing this world ordered by the seven elements. From then on, humanity was confined within this 'order of the seven.'"

"The Seven Rulers of the Mortal Realm, using the 'Heart of God' as their proof, obtained authority over the ley lines flowing with the seven elemental torrents. When a person's desires are conveyed to the heavens, the seven gods must, according to the command of heavenly principles, bestow fragments of their own control upon that person. Of course, this process of bestowal is entirely governed by the Sky Isle system and is not subject to the management of us, the Seven Rulers of the Mortal Realm..."

The Ice Queen, in winter, dispatched her Fatui followers to the kingdoms of Teyvat to collect the Hearts of God from the Seven Rulers of the Mortal Realm, for this very purpose. She wanted to gather the remains of the Third Adventist, to revive this Prince of Light who could rival the laws of nature.

The elemental power wielded by the "Seven Rulers of the Mortal Realm" also originates from this "Heart of God."

When Raiden Shin forcibly "upgraded" himself to create the Divine Cherry Tree, connecting Inazuma's ley lines with Teyvat's "fate system" and altering Inazuma's history, the tool he used was indeed the "Dream Heart," but it was more than just the "Dream Heart."

The reason it failed to display its divine power in the hands of the Shadow for five hundred years is not only because the Shadow and the True One's ideals were incompatible and could not resonate with "Dream of One Mind," but also because she abandoned the "Heart of God" that contained "power from beyond the world."

The "complete version" of "Dream of One Heart" should contain the power of the "Heart of God".

When Shin was on his deathbed, he entrusted Kage with not only "Dream Heart," but also "Heart of God," which symbolized the authority of the "Seven Rulers of the Mortal World."

If "Dreaming with One Heart" is the "pen" used to rewrite history, then "The Heart of God" is the "ink".

A worn-out pen cannot write words.

Unfortunately, the Empress, in pursuit of what she believed to be "eternity," created an "indestructible" doll, entrusting the "Heart of God" to the Divine Child for safekeeping. The Divine Child, in order to mitigate the disaster caused by the Evil Star's pollution, then merged the "Heart of God" into the Divine Cherry Tree…

The reason Han Fulai went to such great lengths to travel back 500 years was not only for "preventive medicine," but more importantly, for this reason—

Only at this moment does the shadow retain that "heart of God".

"'Heart of God'..." Ying reached into his robes and pulled out the purple "chess piece".

It was a "chess piece" with two long, horse-like ears, resembling a "knight" in chess.

Han Fulai had seen the "Heart of God" of the Anemo and Geo in the game before. Venti's was "Queen" and Zhongli's was "Castle".

There are six pieces in chess: King, Queen, Bishop, Knight, Castle, and Pawn.

The King and Queen are unique, while the other pieces are in multiples. There are eight soldiers, and two each of the Bishop, Knight, and Castle.

Two bishops, two knights, two castles, and one queen make up the "Seven Rulers of the Earth".

Han Fulai had no way of knowing why the "Heart of God" held by the Seven Gods was shaped this way, but at this moment, he knew he should make this "Heart of God" do something.

“Let’s combine it with ‘One Dream, One Heart’,” Han Fulai said.

Ying Yiyan placed the "Heart of God" on the blade.

Strangely enough, when the "Heart of God" came into contact with the "Dream Heart," it merged into it like a river flowing into the ocean, becoming one with it.

At the same time, "Dream Together" has also changed its appearance.

It turned into a beam of light.

Originally a physical blade, after merging with the "Heart of God," it became a beam of "heavenly light"—a light held in someone's hand.

“This is…” Ying stared in astonishment at the “Dream One Heart” in her hand.

She had never seen "Dream Together" look like this before, not even when it was still in her sister's hands.

Han Fulai simply nodded calmly, as if he had long anticipated the change in the knife:

“We have successfully put ‘Dream Together’ into a ‘superposition state’… Quantum entanglement across time and space has been established, and we can begin ‘the future saving the past’.”

-----

Before taking the divine child on his journey through time, Han Fulai spent a long time pondering a question.

Why is it that only Lei Movie remembers that the Divine Cherry Tree didn't exist before Inazuma?

Assuming Lei's memories are accurate, and she is the only one in the world who is "sober while everyone else is drunk," then what makes her so "sober"?

Because she is a demon god, one of the "Seven Rulers of the Mortal World"?

No, that's definitely not the reason.

As "Descendants," he and Ying have very special identities, perhaps even more so than the Demon God, yet they are unable to detect the abnormality of the Divine Cherry Tree.

The Divine Cherry Tree had long since become one with Inazuma's "background," existing as naturally as air, and theoretically no one should be able to detect anything unusual.

The abruptness of the divine cherry trees pointed out by Han Fulai was the result of "logical thinking" rather than "emotional perception." He only discovered these doubts after establishing the question, "Just because it has always been this way, does that mean it's right?"

His intuitive understanding—the fox-shaped cherry tree he had once leaned against, and the five-hundred-year-old cherry tree he had just touched—were all real entities.

Lei's understanding of the Divine Cherry Tree is not based on logical thinking; she approaches it through a very emotional lens, using reasons like "I don't remember it."

Han Fulai then went on to think further about the special characteristics of "thunderous movies".

Raiden Shin and Raiden Movie, or rather, Baal and Balzeb, are rare anomalies among the Daedric Lords—at least within the entire continent of Teyvat, they are the only pair of twin Daedric Lords.

Medical research on Earth suggests that a special phenomenon similar to "telepathy" exists between identical twins. Although rare, some identical twins can indeed sense each other's joys and sorrows even when they are far apart, and their emotions seem to resonate with each other.

In quantum mechanics, there happens to be a pair of "twins" with "telepathic" abilities—the famous "quantum entanglement".

Albert Einstein, one of the greatest physicists of the 20th century, spent nearly thirty years of the rest of his life after proposing the theory of relativity battling quantum entanglement—a phenomenon in quantum mechanics that does not adhere to locality and causality, which he called "spooky action at a distance."

Microscopic particles possess a unique phenomenon called "spin," similar to a ping-pong ball that can spontaneously generate "topspin" or "bottomspin"—it's not surprising that particles spin, after all, the Earth rotates. What's strange is that their direction of spin exhibits a "nonlocality" that transcends all distances.

Imagine a stationary, spinless particle that suddenly explodes. It splits into two identical particles, A and B, which then spin and move away in opposite directions. According to the principle of conservation of angular momentum, the two particles A and B must also be spinning at opposite angles, one "upspin" and the other "downspin".

Up to this point, everything is easily understood using normal logic. The problem lies in "observation."

Before observation, people do not know which of the two particles, A and B, is "spin up" and which is "spin down"—in quantum mechanics terms, the two particles, A and B, always maintain a "superposition state" of "spin up" and "spin down".

The instant scientists observe particle A, it collapses from a superposition state into a fixed rotational state, such as an "upspin" state. At the same time, particle B in another direction also instantly exhibits the opposite rotational state, namely "downspin".

In other words, microscopic particles only determine whether they are "spin-up" or "spin-down" when people observe them; observation determines the direction of the particle's rotation.

The key lies in that "moment"—theoretically, both particles A and B are in a "superposition state" with uncertain rotation directions. Each of A and B has a 50% chance of "spinning up" or "spinning down". So why would particle B collapse into a fixed state the moment particle A is observed? Particle B was not observed!

However, no matter how many times scientists try, no matter how far apart the two particles A and B are, they always exhibit this instantaneous characteristic of rotating in opposite directions, as if an invisible thread is entangled between the two particles. If you move one end of the thread, the other end will move as well.

This phenomenon was thus named "quantum entanglement".

According to the principle of "locality", there must be a cause before there is an effect. Particle A must be observed and collapsed first before particle B will collapse as well—just like you have to pull the puppet string in your hand before the puppet on the other end of the string will move.

However, the "thread" entangled between quantum particles transmits force at a speed that exceeds the speed of light!

Particles A and B are in an absolutely instantaneous state of opposites, completely synchronized, without even a nanosecond delay.

Based on the properties of "quantum entanglement," scientists have envisioned its amazing application—transparent spacetime communication.

If this kind of instantaneous sensing that transcends time and space could be controlled by humans, it might be possible for people to transmit information to their past or future selves.

Han Fulai then thought that there might also be such "quantum entanglement" between the twin demon gods Lei Yingdian and Lei Dianzhen.

If the sudden appearance of the Divine Cherry Tree was indeed caused by lightning, is it possible that the Shadow's perception of the Divine Cherry Tree is actually a message that transcends time and space?

It's like someone suddenly has a set of numbers in their head, uses those numbers to buy lottery tickets, happens to win a big prize, and then says that this big prize is a "divine revelation" from God.

Most lottery players on Earth who claim to have received "divine revelation" are actually scammers colluding with the lottery organizers. However, if we want to scientifically explain this kind of "divine revelation," it is "quantum entanglement" information that transcends time and space.

He would confidently tell the shadow, "Raiden is still alive," and his confidence comes from "quantum entanglement."

The "authority" that Raiden Shin left to Kage to change Inazuma's history is also hidden within "quantum entanglement."

Chapter 255 Believe in Him, and You Can Change the World [4k]

The "Heart of God" merged with the "One Heart of Dreams," and the physical "knife" became the intangible "light"... Even holding this light in his own hands, Lei Movie still couldn't understand how this happened.

The goddess felt the same way—the abstract and chaotic "higher-dimensional space," the history of Inazuma that had been altered once but no one noticed, and the sacred cherry tree that was about to be "erased"—everything was a plot that could only be found in "fantasy novels," yet it all happened right in front of her.

Moreover, it seems that Han Fulai had foreseen everything in advance.

The "Heavenly Fox" of Bai Chen's bloodline has always prided itself on its supernatural powers, but compared to the "Heavenly Eye" that claims to be able to see the future, Han Fulai's "precognition" ability is the real "supernatural power," isn't it?

Although his words were difficult to understand, the facts before our eyes have consistently proven him right...

At this moment, both Shadow and Divine Child thought the same thing—to trust him was the right thing to do.

Believe in him, and you can change the world.

For Han Fulai, all of this was certainly not some kind of metaphysical prediction, but rather logical reasoning based on theoretical foundations.

Once you have a sufficient understanding of Teyvat's "fate system," also known as the "false heavens," you can naturally try to use its rules to "change the world."

Traveling through time and space, changing history, changing the world with one's own "will"... These things seem like absurd fantasies to ordinary people, but in Han Fulai's eyes, they are all in line with the spirit of science.

After all, he comes from a country that writes "scientific and materialistic" into every child's textbook.

The questions that Shadow and Goddess encountered were ones he had already encountered when he read popular science books during his university years.

The development of quantum mechanics has led humanity to a very "philosophical" cognitive barrier: does the world exist in our subjective perception or is it a real, objective existence?

The various counterintuitive experimental phenomena in quantum mechanics have brought countless puzzles to humankind.

The wave-particle duality of light tells us that an object can be both a wave and a particle, and whether it is a wave or a particle depends on how you observe it.

The concept of "superposition" tells us that a cat can be both dead and alive.

The "delayed choice experiment" allows the world to no longer follow the law of causality.

The unique action at a distance, which exceeds the speed of light, of "quantum entanglement" makes one feel that even space itself is not real.

What's even more terrifying is that it seems humanity will never be able to find the truth.

Modern physicists can only admit that quantum phenomena cannot be understood intuitively.

No matter how much humanity understands and summarizes these patterns, deep down, no one truly understands "why this is so."

The development of quantum mechanics has made people realize that humans cannot transcend the current dimension of the world to perceive and understand it, and may even have already touched the true limit of human scientific development... It seems that humans cannot even figure out whether they live in a "real" world.

The shock that humanity on Earth experienced when it first encountered quantum mechanics was no different from the shock that humanity on Teyvat experienced when it discovered the "false heavens".

There is probably nothing more despairing than the thought that "the world is an illusion." If there is, it might be the thought that "we do not have free will, and our fate is not in our own hands."

But... science doesn't care about such things.

Science never studies those so-called ultimate, essential, unknowable, and ultimately meaningless questions.

Science studies only the objective laws that humanity can currently understand. Even if the objective world doesn't exist, we still treat it as such. Science only cares about what is helpful to us, regardless of whether it's illusory or real.

The so-called scientific spirit is actually a philosophy of life that encourages us to explore the known aspects of civilization even when the truth is terrifying or even unknowable.

Based on this philosophy, even if humanity can never break through the current world dimension, it can still enjoy the value and meaning of civilization's existence.

As a small-town test-taker who grew up under a "scientific and materialistic" education, especially one who tried to switch to coding for postgraduate entrance exams and wrote his own programs, Han Fulai has his own way of understanding the "ultimate questions" that humanity encounters when exploring the world.

—If you treat those incomprehensible quantum phenomena as virtual game world settings, they become much easier to understand.

For example, the "wave-particle duality" means that an object is both a wave and a particle, existing in a "superposition" state. This is difficult to understand in real life, but it is perfectly normal in the game world.

In the game world, matter can be both a wave function and a deterministic value at the same time. For example, a random function is a random range when the program is not running, but becomes a deterministic value after it is run (observed).
