Time flies very quickly. Before the night comes, Ye Yu and Lin Yueru have already arrived at the largest city in District 11, and are also the administrative center of District 11 - Tokyo Concession 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 District, most of the British civilians and nobles who immigrated from the Holy Britain, as well as a small number of honorary British people.

As for the original Japanese, that is, the current eleven, (eleven: the British despicable name for the Japanese, meaning people in District 11, and they are also translated as numberers.)

At this time, Ye Yu and Lin Yueru had already got off the Shinkansen intercity rail train, transferred to the outer circle of the ring line 5, and entered the Tokyo Concession Area.

"Inside, it's the Tokyo Concession District." Ye Yu pointed to Lin Yueru and said to his right.

"Wow, I feel that the left and right are completely different worlds." Lin Yueru looked at the windows on both sides of the train and sighed.

In Lin Yueru's view, the world on his right is extremely prosperous, with tall buildings and neon lights like a sea of ​​joy.

The world on the left is pitch black, looking extremely dilapidated, but there are ruins everywhere, making it extremely sad.

"The outer circle of this circular line 5 was originally Japan's jr Yamanote line, which was moving clockwise." Ye Yu explained to Lin Yueru, "If you look at the Yamanote line as a circle, the Tokyo Concession where the people of the British Empire live, and the outside of the circle is a dilapidated and poor, like a ruined and ruined settlement. This is the best portrayal of the British Empire's cruel exploitation and exploitation of the colonial areas."

"This British Empire is really hateful!" Lin Yueru suddenly felt sympathy.

"It's just that there are different positions." Ye Yu said calmly.

"By the way, Ye Lang. Since you let Xiao Yan go back to the past, that is to say, the one who left us information in the Tokyo Daily before was Xiao Yan who had been back to the past for a long time, why not directly contact Xiao Yan?" Lin Yueru asked the biggest question in her heart.

"Because Xiaomeiyan is not on the line of our world." Ye Yu replied.

"World Line?" Lin Yueru suddenly didn't understand.

"Well, based on my private exchange and discussion with Akami Hokage and her own research, we can basically be sure that the virtual world in the causal game uses the world line closing theory."

"The so-called world line closing theory is a model suitable for users to be bound by the law of causality, such as the plot protection mode."

"Let me give an example. We have to go from point a to point b. This is a node. That is to say, we will go from point a to point b, which is a world line closing. Point b is the result of a closing."

"No matter which route we go through during the process, we will eventually go to point b. This is the result of being bound by the law of cause and effect, which leads to the convergence of the world line."

"For example, there is a hemp rope that extends from the starting point to the end point, and it looks like there is only one line. But if you look at this hemp rope closely, you will find that the hemp rope is bound by many small cables. The thin cables above are the world line, and the hemp rope bound by small cables will go to the same common end point."

"Uh..." Lin Yueru was already a little dizzy when she heard it. But she still asked stubbornly, "Then why is Xiaomeiyan not on our world line?"

"This is because, according to the theory of parallel universes derived from quantum physics, if someone returns to the past and interferes with the past, it will change the world line. It is like a river, someone runs from the downstream to the upper reaches to build a dam, which turns the river redirected. Originally, the direction of the river was a, but after the person returns to the upstream, the direction of the river became a river b."

"River a and river b are two different world lines, these are two parallel universes. A magical world in a superposition state. Finally, after the law of cause and effect is bound by the world line, river a and river b will flow to the same estuary and eventually enter the ocean. Do you understand this way?"

"Uh... I still don't understand =.="

"Okay, I'll just say it briefly. The world line we are in now, such as the world line a. So Xiaomeiyan went back to the past alone, then any behavior she did in the past will lead to changes in the future. The result will lead to the birth of a new parallel universe, which is the world line b. The world line b has the ‘Xiaomeiyan who returned to the past’, and the world line a we are in now does not have ‘Xiaomeiyan who returned to the past’. So we cannot contact it. Only when the timeline moves to a certain point of causal law constraint, because of the world line, all different world lines will be closed to the same point, and then we can meet with Xiaomeiyan."

"Since the world line we are in, there is no 'Akimi Hokage who returns to the past'. Then why can we see the advertisement Xiao Yan made in the Tokyo Daily?" Lin Yueru asked with her forehead covering.

"This is quite complicated. This involves the superposition state theory of quantum physics, which can also be called information interference theory. This theory means that different world lines in the same quantum universe are divided into many independent branches in the three-dimensional dimension. However, in a higher dimension state, all different world lines are derived from a magic superposition state."

"Take the famous Schrödinger's cat as an example. In the three-dimensional dimension, there is a world line in which a cat dies and a world line in which a cat lives. But in a higher dimension, there is also a superposition state where cats are both dead and alive at the same time!"

"Uh... I can't understand at all." Lin Yueru's eyes were already confused.

"It is always difficult to imagine high dimensions with low dimensions, but it is 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. Project a three-dimensional cone on two vertically intersecting two-dimensional planes. Then if we are on plane a, we will get a triangle projection, and on plane b, we will get a circular projection."

"If plane a and plane b live in a group of two-dimensional living organisms, then plane a two-dimensional living organisms will claim that the cone they observed is triangular. Plane b will claim that the cone they observed is circular. If both sides can communicate across dimensions, they will cause fierce debate because of what shape the cone is."

"But in fact, they are not wrong. The cone projected on plane a is indeed a triangle, and the projected on plane b is indeed a circle. However, from a two-dimensional life body, from a two-dimensional perspective, it is hard to imagine that there will be a superposition shape in the world that is both a circle and a triangle. But in fact, if we look from our three-dimensional perspective, it is easy to know that this superposition state, which is both a circle and a triangle, is just a cone."

"So in fact, under a higher dimension, there is a main world line superimposed with all world lines. This main world line is in a super high dimension. Under this dimension, there will be countless three-dimensional parallel universes, which are the so-called sub-world lines. The superposition state of the main world line will be projected onto countless three-dimensional worlds, forming their own different results, that is, forming different sub-world lines. But these sub-world lines will eventually lead to the same result due to the constraints of the law of causality, and all sub-world lines will follow the trajectory of the main world line."

"This is the truth about the plot protection mode."

"If you use an image metaphor to describe the virtual world created by the causal game, there are three plot modes."

"There are countless tiny ropes, and these countless tiny ropes are sub-world lines, representing the possible interference of players to the world."

"The plot protection mode is to tighten countless small ropes to form a thick hemp rope, and then the law of causality will place the hemp rope according to the established trajectory."

"The plot destruction mode: it is to deliberately untie countless small ropes to disperse them and make them deviate from the established trajectory."

"The plot opening mode: it is to loosen all the small ropes, not tighten or untickle them. As long as the player's behavior causes interference, the rope will infinitely amplify this interference, causing unpredictable changes in the hemp rope."

"Back to the question just now. Normally, what Akami Hokki's doing at World Line B cannot affect the world line a we live in."

"But in very special circumstances, different world lines will interfere with each other due to the influence of superposition. This special situation is the relationship between me and Akami Yan."

"As my summoning character, there is some kind of contractual relationship between her and me."

"So when Akamiyan returns to the past and interferes with changes in the past and makes herself enter the world line b. Because of the contractual relationship between me and her, Akamiyan can appear in the world line a through the influence of superposition states when Akamiyan performs certain low-interference behaviors on the world line b."

"The so-called low-interference behavior is the change after superposition, which will not affect the changes in our world line a. For example, Akami Hokki's advertisements in Tokyo Daily according to the password table we agreed in advance are low-interference behaviors, so we can accept the superposition change of this interference and thus receive this information."

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

When Ye Yu finished talking about this whole lot without breathing, Lin Yueru's eyes had turned into a bunch of stars.

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

And at this moment, the gentle announcer's voice on the city rail train rang.

"Lincoln Avenue Station has arrived. Please get off the bus in time."

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

"Let's go, we are about to face the first causal law constraint... The terrorists steal the plot point of the cc queen!"
