Time flies quickly, and before the night comes, Ye Yu and Lin Yueru have already arrived in the Tokyo Concession District, the largest city in the 11th district and the administrative center of the 11th district.

The Tokyo Concession was the main administrative center and colony of the British Empire in Japan, and was converted into a fortress city.

In the Tokyo Concession, most of the lives were made up of British commoners and nobles who had emigrated from Holy Britain, and there were a small number of honorary Britons.

As for the original Japanese, which is now Eleven, (Eleven: British's contemptuous term for the Japanese, meaning from the 11th district, also translated as numberer. ）

At this time, Ye Yu and Lin Yueru had already gotten off the Shinkansen intercity rail train, transferred to the outer circle of Circular Line 5, and entered the Tokyo Concession area.

"Inside is the Tokyo Concession area." Ye Yu pointed to Lin Yueru and pointed to his right hand and said.

"Wow, I feel like the left and the right are two worlds entirely." Lin Yueru looked at the windows on both sides of the train and sighed a little.

In Lin Yueru's view, the world on the right hand side is extremely prosperous, with high-rise buildings and neon lights like a sea of joy.

The world on the left-hand side is pitch black, looking extremely dilapidated, but everywhere there are ruins and broken walls, which looks extremely sad.

"The outer ring of this circular Line 5 was originally Japan's JR Yamanote Line, and it travels in a clockwise direction." Ye Yu explained to Lin Yueru, "If you look at the Yamanote Line as a circle, inside the circle is the Tokyo Concession, where the people of the British Empire live, and outside the circle is the dilapidated and impoverished Eleven settlement like a ruin. This is the best portrayal of the British Empire's brutal exploitation and oppression of the colonial area. ”

"This British Empire. It's disgusting! Lin Yueru's sympathy was overflowing all of a sudden.

"It's just a different position." Ye Yu said indifferently.

"That's right, Ye Lang. Since you let Xiao Ho go back to the past by herself, that is. The message that left us in the Tokyo Daily before was that Xiao Yan had been going back to the past to investigate for a long time, so why not contact Xiao Yan directly? Lin Yueru asked the biggest question in her heart.

"Because Xiao Meiyan is not in our world." Ye Yu replied.

"World Line?" Lin Yueru didn't understand it all of a sudden.

"Well, based on my private discussions with Xiao Meiyan, plus her own research. We are almost certain that the virtual world in the game of cause and effect. The worldline convergence theory is used. ”

"The so-called worldline convergence theory is suitable for users to be bound by the law of cause and effect like the plot protection mode."

"I'll give you an example. We're going to go from point A to point B. This is a node. In other words, we will go from point A to point B, which is a world line of convergence. Point B is the result of a constriction. ”

"It doesn't matter which route we take along the way. Eventually, it will all go to point B. This is the result of being bound by the law of cause and effect, and the line of the world is bound. ”

"For example, there is a hemp rope that runs from the beginning to the end and looks like there is only one line. But if you look at this hemp rope closely, you will find that the hemp rope is made of many small cables tied together. The thin rope on top of this is the world line, and the hemp rope bound by the thin cable will lead to the same common end. ”

"Forehead......" Lin Yueru was already a little dizzy when she heard it. But she still stubbornly asked, "Then why is Xiao Meiyan not on our worldline?" ”

"It's because. According to the theory of parallel universes deduced from quantum physics, if someone goes back in time, it interferes with the past. will make the world line change. It's like a river, and someone runs from downstream to upstream and builds a dam, and the river is diverted. Originally, the direction of the river was River A, but after this person returned to the upstream and diverted, the direction of the river became River B. ”

"River A and River B are two different world lines, these are two parallel universes. A magical world in a state of superposition. Finally, after the binding of the law of cause and effect, after the world line is closed. Both A and B will flow to the same estuary and eventually into the ocean. Do you get the idea? ”

"Uh...... Still don't understand =. =”

"Well, I'll just keep it simple. The world line we are in now, for example, is the world line A. Then Xiao Meiyan herself goes back to the past, so any behavior she does in the past will lead to changes in the future. As a result, a new parallel universe will be born, which is World Line B. World line B has 'Xiao Mei Yan who has returned to the past', and World Line A where we are now does not have 'Xiao Mei Yan who has returned to the past'. So we can't make contact with it. Only when the timeline travels to a certain point of the law of cause and effect, because of the convergence of the world line, all the different world lines will converge to the same point, and then we can converge with Xiao Meiyan. ”

"Then since we are in the world line A, there is no zài 'Xiao Mei Yan who has returned to the past'. So why can we see Xiaoyan's advertisement in the Tokyo Daily? Lin Yueru asked, covering her forehead.

"This is more complicated, and it involves the superposition theory of quantum physics, which can also be called the theory of information interference. What this theory means is that the different world lines of the same quantum universe are divided into many independent branches in the three-dimensional dimension. But in the higher dimensional states, all the different worldlines are in a magical superposition. ”

"Take, for example, the famous Schrödinger's cat. In the three-dimensional dimension, there is a world line where a cat is dead, and a world line where a cat is alive. But in a higher dimension, there is still a zài, a superposition of cats that are dead and alive at the same time! ”

"Uh...... Completely incomprehensible. Lin Yueru's eyes were already foggy.

"It's always more difficult to imagine higher dimensions in lower dimensions, but it's much easier if we imagine two dimensions in three dimensions."

Ye Yu gave an example and said: "Take a three-dimensional cone as an example. A three-dimensional cone is projected onto two two-dimensional planes that intersect vertically. So if we are in plane A, we get a triangular projection, and in plane B we get a circular projection. ”

"If a group of two-dimensional beings lives on each plane A and plane B, then the two-dimensional beings on plane A claim that the cone they observe is triangular. Plane B, on the other hand, would claim that the cone they observed was circular. If the two sides can communicate across dimensions, there will be a heated argument over what shape the cone is. ”

"But in reality, none of them are wrong. The cone projected onto plane A is indeed triangular, and the projection onto plane B is indeed circular. It's just that two-dimensional lifeforms, from a two-dimensional perspective, it is difficult to imagine that there will be a superimposed shape that is both a circle and a triangle in the world. But in fact, if we look at it from a three-dimensional perspective, it is easy to see that this superposition of circles and triangles is nothing more than a cone. ”

"So in fact, under the higher dimensions, there is a main world line that superimposes all the world lines. This Overworld line is ultra-high-dimensional. Under this dimension, there will be an infinite number of three-dimensional parallel universes, which are called subworld lines. The superposition of the main world lines will be projected into countless three-dimensional worlds, forming different results, that is, forming different sub-world lines. However, these sub-world lines will eventually be bound by the law of cause and effect, so that all sub-world lines will follow the trajectory of the main world line and move towards the same result. ”

"That's the truth about the plot protection mode."

"If you use a figurative metaphor to describe the virtual world of the causal game creation zào, there are three plot modes."

"There are an infinite number of tiny ropes, and these countless tiny ropes are sub-world lines, representing the interference that the player may have with the world."

"The plot protection mode is to tighten countless thin ropes to form a thick hemp rope, and then the law of cause and effect places this hemp rope according to the established trajectory."

"Plot destruction mode: It is to deliberately untie countless thin ropes and let them spread out. to deviate from the established trajectory. ”

"The plot is open mode: it is to loosen all the small ropes, do not tighten or untie, as long as the player's behavior causes interference, the rope will infinitely amplify this interference, making the hemp rope unpredictable changes."

"Back to the question I was asked earlier. Normally, what Xiao Meiyan does in World Line B does not affect World Line A where we are. ”

"However, in very special cases, different world lines will interfere with each other due to the influence of superimposed states. This special case is the relationship between me and Xiao Meiyan. ”

"Xiao Meiyan is my summoning character, and there is a certain contractual relationship between her and me."

So when Xiao Meiyan went back to the past, the interference changed the past and made herself enter the world line B. Because of the contractual relationship between me and her, Xiao Meiyan can appear in world line A through the superposition of the influence when she performs some low-disturbing behavior on the world in world line B. ”

"The so-called low-interference behavior is the change after superposition, which will not affect the change of our world line A. For example, Xiao Meiyan published an advertisement in the Tokyo Daily according to the password list we agreed on in advance. It is a low-interference behavior, so we can receive the superposition of this interference, so as to receive this information. ”

"This is the so-called information interference theory of the quantum universe."

When Ye Yu finished talking about this big pile without breathing, Lin Yueru's eyes had already turned into a pile of stars.

"Ye Lang, although I don't understand what you're talking about at all, I feel so powerful!"

And at this moment, the gentle announcer voice on the city rail train sounded.

"Lincoln Avenue Station has arrived, please get off the train in time for arriving passengers."

After hearing this, Ye Yu immediately got up and pulled Lin Yueru out of the car door.

"Let's go, we're about to face the first causal binding point now...... Terrorists steal the plot node of the CC Queen! ”
