Fingal really has nothing to say about his efficiency.

The list of students in the academy is kept secret in Norma's underlying database, and theoretically only the authority of the full-time professor or above can be transferred, even if Fingal is the actual developer of Norma, there is no way to bypass the permission verification.

But it only took him three days to do it.

Gu Bei could only sigh with emotion, worthy of being the top hacker hidden behind Eva, the king of the paparazzi in Kassel.

Students from level 82 to level 84 have a corresponding graduation time of 86 to 88 years, and although Chu Tianjiao has lost the traces of studying in Kassel due to the correction of fate, if he graduates normally and joins the executive department, it should be level 83, that is, he will graduate in 87.

Actually, there's a small bug here.

According to the correction of fate, if Chu Tianjiao did not join Kassel, he naturally did not enter the executive department, so he would not have taken over the task of investigating Odin or Nidhogg, and there would be nothing afterward.

will not come to Huicheng, will not know Su Xiaoyan, and will not give birth to Chu Zihang.

But the actual reality is that Chu Tianjiao not only took over this task, but also came to Huicheng like the guidance of fate, met Su Xiaoyan, and gave birth to Chu Zihang.

This is contradictory.

There are two explanations for this question.

First, the world line is closed.

Gu Bei watched an anime called "The Gate of the Destiny Stone" when he hadn't crossed over, and the male protagonist in it could be an observer who kept shuttling through different world lines and witnessing different stories of the same group of people.

In this story, the male protagonist is the anchor of the world line, let's call it 1.

And all the world lines are divided into two categories.

Less than 1 and greater than 1.

In all the world lines less than 1, the most important closing point is the death of the male protagonist Aomei.

So Qingmei's death is inevitable, no matter how the male protagonist comes up with various ways to avoid death, he will eventually take Qingmei to another death ending.

Even if he takes Qingmei to a place where there is no danger, Qingmei may suddenly die of a vicious illness.

And in the world line greater than 1, this closing point is the death of the heroine.

In other words, the male protagonist, as an observer1, needs to choose between the green plum and the female protagonist, and then abandon half of the world line and stay in the other half.

All in all, one of these two had to die.

This is the end of fate.

At the end of the story, the male protagonist finds a way to deceive fate, making his past self mistakenly think that the heroine is dead, and opening the only world line where the heroine and Qingmei all survive.

This world line is the "Gate of the Stone of Destiny".

The story is well told, but the reality is cruel.

As the end of fate, the female protagonist and Qingmei are bound to die one, and then the male protagonist takes the other one and walks towards the future with guilt, which is the right choice.

It's also possible that both of them will survive, and that fate itself is so twisted.

Ahem, it's far away, talking about the problem of recycling the bundle.

The first possibility that Gu Bei guessed: Chu Tianjiao and Su Xiaoyan gave birth to Chu Zihang, which was a binding point of fate.

Because Chu Zihang must exist, even if Chu Tianjiao did not join Kassel, he still came to Huicheng to investigate Nidhogg, met Su Xiaoyan, and gave birth to Chu Zihang.

Originally, this theory was infallible, but just three days ago, the appearance of a person broke Gu Bei's conjecture.

The mysterious man who had been to Chu Tianjiao's residence.

The man said that he was an alumnus of Chu Tianjiao, and also took out a photo of himself and Chu Tianjiao in the academy.

This means that Chu Tianjiao's traces in Kassel exist.

But in the previous time, Gu Bei asked Ange to investigate Chu Tianjiao's file, which clearly showed that there was no such person.

The statements of these two men contradict each other, in other words, one of them is lying.

Is it the mysterious man, or is it Angers?

The answer is...... Neither.

There was no need for these two people to lie, and the mysterious man could sneak directly into Chu Tianjiao's residence without revealing his identity, but he still entered it through normal channels, indicating that his identity could withstand verification.

Ange had no need to deceive Gu Bei at all.

But since neither of them is lying, why are they saying the exact opposite?

Gu Bei also thought of a possibility after thinking about it these days - the world lines overlapped.

The world line does not exist independently, but is like a tributary of a river that forks, and two tributaries that flow in the same direction will have a certain probability of reconverging, and this phenomenon also exists on the world line, that is, the world line overlaps.

The overlapping world lines have shaped two Chu Tianjiao in the same world, one of which is Chu Tianjiao, who came to Huicheng after graduating from Kassel, and was then stabbed by Odin.

Chu Tianjiao, who the mysterious man knows, is also this one.

And Chu Tianjiao, whom Ange knows, is also a passerby, this Chu Tianjiao did not enter Kassel, he is a wild half-breed, and the only commendable thing in this life is that he has such a son as Chu Zihang.

Of course, there are some people who are exceptions.

For example, Gu Bei, the Chu Tianjiao he knew was hearsay, and in his cognition, the two Chu Tianjiao all existed in quantum superposition.

Another example is Su Xiaoyan, in her cognition, there is only one Chu Tianjiao, because Chu Tianjiao of the two world lines carried out the same actions after arriving in Huicheng, in other words, Chu Tianjiao, who is different from these two people, was restrained by the world line after arriving in Huicheng and became the same person.

Therefore, there is only one Chu Tianjiao in Su Xiaoyan's world, no matter which world line this Chu Tianjiao is in, he will fall in love with Su Xiaoyan, marry her, have children, and give birth to Chu Zihang.

This is known as the Fate Restraint Theory.

There is another explanation, which Gu Bei calls the reversal of cause and effect.

The cause is determined by the results.

Chu Zihang escaped because he was in the Nibelungen of Odin when his fate was corrected, and the result of this was that Chu Zihang's existence could not be erased.

The result is that Chu Zihang still exists.

And the reason is that Chu Zihang was born.

The fact that Chu Zihang was born is certain, so the reason why Chu Tianjiao and Su Xiaoyan are together is also determined.

So even why he came to Huicheng with Chu Tianjiao, and his past were all corrected by fate.

But in that case, there is no way to explain why there is no record of Chu Tianjiao in Kassel's files, and Ange does not remember such a person.

So going round and round, this speculation finally pointed to the reason for the overlapping theory of the world line.

In general, the overlap of the world lines is determinable.

Originally, Chu Tianjiao of the two worlds existed independently, just like the front and back of a paper ring.

Kungunir eliminated one of Chu Tianjiao's existences.

But this Chu Tianjiao's life is too exciting, and it also left Chu Zihang, an unexplainable bug, so in order to rationalize everything, the world line began to repair itself, connecting the front and back of the paper ring together.

This is also known as the Möbius Ring.

And Chu Zihang is the most critical connection point that forms this Möbius ring.

Gu Bei asked Fingal to investigate the students of the same period as Chu Tianjiao, firstly, to find out the true identity of the mysterious man who remembered Chu Tianjiao, and secondly, to make an attempt. net

According to the current situation, Chu Tianjiao's existence can only be judged after being observed, that is to say, when Chu Tianjiao is not observed, the faculty and staff of Kassel, as well as Chu Tianjiao's former contemporaries, will not remember Chu Tianjiao's existence.

They are located on the front of the paper ring.

And Chu Zihang and the mysterious man, the people who remember Chu Tianjiao, are on the back of the paper ring.

And Su Xiaoyan is not clear

The person who is the truth of the matter is on the positive and negative sides of the Möbius ring at the same time.

But Gu Bei is different, he stands outside the paper ring.

And what he has to do now is to try to drag the person on the front of the paper ring to the back of the paper ring, and force people to complete the leap on the world line.

Normally, this is difficult to do, as it involves a change in the higher dimensional forces.

Gu Bei estimated that if he wanted to do this easily, he had to practice the Daluo Cave Meditation to perfection.

But now the situation is exceptional.

Because Chu Zihang used the incision to connect the two sides of the paper ring into a Möbius ring, strictly speaking, the two world lines are connected.

What does this mean?

It means that there are two possibilities for all people in this world at the same time.

For example, a person was killed by Chu Tianjiao in the world line on this side, but he was alive and well in the other world line.

Then as long as Gu Bei finds a way to let the other party walk through the connection of the world line and come to the world line on the back, this person will be able to remember that he has been killed.

As for whether this person will live to preserve his memories after death, or directly burp on the spot, Gu Bei does not know, which is also the purpose of his experiment.

If it was just to obtain memories, then the next time Gu Bei met Chu Tianjiao, he could send him to another timeline to recover his memories, and then pick him up and give Chu Zihang a complete father.

If it has an impact on the state of existence, then the matter will have to be considered in the long run.

Alas, for the sake of his senior brother's dear father, Gu Bei is really heartbroken.

Gu Bei sighed at his unrestful hard work, and at the same time opened the two lists sent by Fingal, one is the graduation list of students from 82 to 84, and the other is the list of those who have joined the executive department among these students, as well as the time of joining the department.

After roughly flipping through it, Gu Bei suddenly frowned.

These two lists are not quite right.

I won't mention Chu Tianjiao's file here, after all, Chu Tianjiao is the existence of Schrödinger, and it is normal for Kassel to have no records, but there are still some familiar names missing here.

Like what...... Lulin City.

Lu Lincheng, Lu Mingfei's father, according to Lu Mingfei's own oral account, he was born in 1990, when his father was 25 years old.

To convert, Lu Lincheng was born in 1965.

Extrapolating from the age of birth, it can be concluded that Lu Lincheng entered school at the age of 18 in 1983.

and Chu Tianjiao at the same time.

Taking a step back, even if Lu Lincheng was talented and enrolled a year earlier like Gu Bei, he would still be an 82-level student.

And according to the information provided by Ange, Lu Mingfei's mother, Giovanni, met Lu Lincheng when he was in school, and the two were at the same time.

After graduation, the two joined the executive department and carried out tasks in the north and south, so they left Lu Mingfei to their uncles and aunts, so that Lu Mingfei's childhood lacked the company of his parents.

In other words, the two lists in Gu Bei's hands, no matter which one they are, should have the names of Lu Lincheng and Giovanni.

But the result is...... None of them.

Gu Bei frowned and sent a message to Fingal: "Are you familiar with this list?"

Fingal: "???"

"Oh, I'm asking, where did you get this list?"

"Let Norma dig it out of the underlying database," Fingal boasted, "You don't know, this thing is blocked several layers, and the encryption at the bottom actually requires the principal's permissions, and it took me two sets of photos to get the principal's card."

The corners of Gu Bei's mouth twitched, and he replied, "Then I'm afraid you'll be cheated by the vice principal."

「？？？」

"This list is wrong...... At least not completely."

"How is this possible, this is the list of all the students in the past, not to mention the 82-level students, even the 02-level students can find out."

The 02 level here is certainly not talking about 200

2, but 1902.

The Kassel Academy was founded in 1901, a year after the Summer Mourning, and Fingal was able to find a list of the 1902 students even from the bottom of Norma, which shows how complete this information is.

But Gu Bei said that the list was incomplete, and in Fingal's opinion, this was impossible.

Gu Bei tapped on the keyboard and pulled out a line of words: "You look up Lu Lincheng and Giovanni in the database."

Fingal didn't move, he should have gone to work.

After a while, Gu Bei received a reply: "Didn't find it...... Who are these two?"

"Lu Mingfei's parents."

Fingal didn't respond for a long time.

Fingal also knew about Lu Mingfei's situation, and naturally knew that Lu Mingfei's parents were the elite of the executive department, but there was no record of these two people in the archives of the academy.

It's a fantasy.

Finally, Fingal came back with a message: "Give me ten minutes."

Gu Bei looked at the time, silently pinched the time, and at nine minutes and forty-four seconds, he received a message from Fingal.

"TD, these dog thieves in the executive department have taken precautions, not only made a separate list of these people, but also cleared all traces of these people from Norma, and the admission records and award records are all gone, turning them into gray men who serve the executive department, if you hadn't reminded me, this time it would have really been planted in their hands."

The bottom attachment is a shared mailbox link.

Gu Bei clicked on it, and he needed to enter the password, and it was Professor Hawking's birthday.

Gu Bei twitched the corners of his mouth, entered Professor Schneider's birthday, and unlocked it smoothly.

Should it be said or not, Professor Schneider's appearance in a wheelchair is indeed somewhat similar to Hawking.

There's a list lying in the mailbox.

Grey List of Special Assignments of the Department of Implementation.
