Yi Cheng, who believes that his imagination and reasoning ability are both erratic, is suffering unprecedented impacts now.

Because, no matter how rich his imagination and reasoning ability are, he never thought that what he experienced this time was such an incredible event.

"You're a brooch?!"

That's right, that's a face that has almost no difference in details. Moreover, after eliminating the possibility of "disguise", Yi Cheng naturally could not regard it as a farce directed and acted by the Red Instructor.

"How should I say this? In fact, I have to take on the responsibility."

Instructor Hong smiled and waved his hand, signaling the excited Yi Cheng to calm down first.

"At the end of the day, I was also trapped in dogmatic empiricism, so I made a wrong decision, which led to this series of events."

"So what the hell is going on?"

Although he was full of doubts, Yi Cheng calmed down now.

Since the woman Hong Tutor has begun to take the initiative to take responsibility, in other words, she must have the absolute and reliable solution to this incident.

It’s not a blind confidence but an incident that can make mentor Hong interested. This is the first time Yi Cheng has seen her since he took office. If it weren’t for the incident itself, she would probably not have been involved in it?

"Actually, things themselves are very simple, so simple that they can be explained clearly by using a simple causal cycle of relationships."

Yi sat down with a comfortable face, and then crossed her thighs gracefully. Instructor Hong waved his hand and signaled the mediator to find a place to sit down. At the same time, he ordered the Soul-Splitting Man to brew a cup of fragrant milk tea for her.

"Okay, don't keep it aside, hurry up and say it, what do you know?"

As a witness to the incident, Yi Cheng really wanted to know what the Hong Tutor noticed during this process and discovered the shocking truth.

Mentor Hong himself ignored Yi Cheng's anxiousness. After siping milk tea and sniffing out the heat in satisfaction, he slowly explained it.

"First, the problem I want to explain is causality."

What is causal relationship?

Simply put, it is the reason why something happens determines the possible result of the event. That is to say, the process of the development of things has an inevitable premise, and at the same time, this premise also determines the final result of the development of things.

There must be a cause, and the cause and effect complement each other and restrict each other. At the same time, in the causal relationship, the sequence of time is strictly followed, that is, there is a cause first and then there is a result.

In addition, in more complex causal relationships, the cause of something may be the result of another event, and the result of this event may also become the cause of another event. Of course, if you continue to extend it, it is a deeper philosophical issue, and there is no need to discuss it here for the time being.

Although it sounds like a tongue twister, most people have a certain understanding of the most basic "cause and effect". What the Red Mentor wants to emphasize here is actually only one of the key points.

"In general, we believe that in the causal relationship, the cause of things comes first, and the result is after the cause."

"Yes, what's wrong with this?"

In fact, this concept was fully reflected in this incident. The reason why the evil villain had to travel through time and space to return to the past is to change the determined causes of the past and thus reverse the result of the Olympic Games held by the Celestial Empire.

In addition, Yi Cheng chose to return to this critical time node, destroying the villain's plan, and also from the perspective of "cause and effect", by aborting the life of "cause", thus changing the final time flow and even collapse.

"But, if you don't see anything wrong with it?"

“Huh?”

This question from Mentor Hong made Yi Cheng slightly stunned.

"I know I know!"

The dragoon next to Yi reacted quickly and immediately waved his hands to indicate that he had seen the truth.

"If it is according to the time the protagonist said, then the cause of this incident is actually born after the result!"

"You can't say that, either."

Although Yi Cheng wanted to refute it, if you think about it carefully, if you look at the order of "time flow", this statement is really correct.

Events born in the future have affected the past, which obviously violates the most critical "time series" in causal relationship

"However, from my point of view, these things should be born in a specific order, so it cannot be said that they violate the order of cause and effect, right?"

"Oh, although that's true, it's because of the subtle contradictions in it that the time flow is disordered."

Instructor Hong smiled and put the milk tea cup in his hand on the table.

"First, let's straighten out the order of the occurrence of these events."

Is the birth order of events?

This was not a difficult thing for Yi Cheng. Soon, he sorted out the rough order in his mind.

First, now, the Red Mentor has obtained information from the Protestant Savior of the British Protestant Church, criticizing the evil villain of the villain organization "Orth of the Phoenix" who wanted to go back to the past and destroy the plan of the imperial capital to hold the Olympics.

Yi Cheng, Bai Ze and the mediator were ordered to use the time machine of the underground warehouse to return to the past 2ooyi years. At the time when the Savior Plan was about to be implemented, they fought wits and courage with the evil villains, and finally won the victory in the first stage and successfully protected the right to host the Celestial Empire.

Due to the malfunction of the time machine in that era, Yi Cheng and the other two had to rely on the ability of the evil villain "breast" to prepare to return to the present through the tearing cracks in time and space.

As a result, at that time, the mediator suddenly turned against him and attacked Yi Cheng and Bai Zeqi, and also said some inexplicable words, and then entered the crack of time and space.

After that, the villain code-named "Brooster" threw Yi Cheng into the space-time crack, and himself entered the space-time crack and returned to the "present". However, Yi Cheng himself, due to the loss of consciousness, came to a brand new future under the influence of the convergence of the time flow.

In this future, the Savior Plan has not been successfully implemented, and the level heroes are still the mainstream of the world. Moreover, the instability of the flow of this time has reached its limit, and there has even been a situation like "two Yichengs exist at the same time", which may completely collapse anytime and anywhere, resulting in subsequent flow of time, including the earth itself, destruction.

"So, until here, I guess you've noticed it too."

The Hong Tutor who interrupted Yi Cheng's explanation and looked at him with a smile.

"In fact, there are two periods of time flows at this time node."

"Yeah, that's right."

Although I have tried to explain this situation in other ways, in the end, Yi Cheng could only think of it as another more reasonable situation, which is the so-called "parallel space".

"So, do you know where the key points of the splitting of these two parallel spaces are?"

"It's not because of me,"

Yi Cheng curled his lips and turned his eyes to the mediator beside him.

"I think it might be the one who made it."

"It may be inaccurate to say that she was doing the trick."

Instructor Hong shook his head.

"However, there was indeed an interesting difference at this time node, that is."

Speaking of this, she looked at the mediator herself with interest.

"Are the mediators who enter the space-time cracks at this time the mediators we know?"

"Why?"

If Yi Cheng thought he was grasping the context of the whole thing just now, then he was completely confused now.

"What do you mean?"

"Oh, what exactly does it mean? You will probably know it later. In short, what's next?"

"Next I'll meet you."

When Yi thought of this, Yi Cheng couldn't help but look red. After all, the little things he did to the Hong mentor in the past were really not easy to tell.

In short, at that time, because the appearance of the Red Tutor, more precisely, was the "Red Mechanic" of the past, he unexpectedly woke up the memories of the past, and then noticed the possibility that the "time machine" might exist, and used this time machine that was intact in that time and space to return to the "past", that is, the time point before his birth.

"It's the second time you've been here in the same period of time, right?"

The crystal, who listened carefully next to him, suddenly asked a question.

"Well, in theory, it is true, and I have confirmed that at that time, there was indeed another me who returned here from the future."

"This is really amazing."

The soul-breaking people next to Yi were all impressed, not to mention that they did not understand this mysterious scientific concept at all. Xuanyuan Cuihua, who came in to listen to the story halfway through the line to listen to the story, looked at Yi Cheng's expression as a true portrayal of "Are you a god or a monster."

Because of the previous experience, Yi Cheng, who returned to the "past", did what he did to avoid "self" as much as possible and confirm which part of the actions was wrong, which led to the splitting of the time node. Moreover, during this action, he also unexpectedly discovered some situations he had not noticed before.

"So, time is indeed very wonderful, right?"

"Yes, yes, I didn't expect that there were some things that were based on the history I knew because of myself."

Faced with the deliberate guidance and questioning of mentor Hong, Yi Cheng also realized the connection between his second "time travel" and the first time.

During the second time travel, he discovered the lies about the "explosion of the database of versus ability" in the Maoxiong Kingdom, and then took out the heroic ability code-named "Sea Emperor" from Chernobyl's base. In a sense, it created a genius girl named "Sea Emperor" in this era.

In addition, the "breast" who is directly related to the incident can escape from the edge of death and become a prisoner because of his reasons. After that, Yi Cheng, who realized that he could choose to solve the problem at the source of the incident, simply used the ability of the brooch to travel back to this "future", and today, he directly solved the evil villain who tried to return to the past to create events.

"In other words, there is also an inevitable causal connection between my second time travel and my first time travel?"

"That's right, and"

Instructor Hong smiled and pursed his lips, licking the foam of the milk tea on it.

"If you notice this point, then another problem will appear, that is."

She stood up, walked to the mediator, and gently placed her finger on her shoulder.

"At that time, it was not just you who did more than one time traveling."

"Wait for you to mean"

Recalling the previous sentence of Mentor Hong, "Are the mediators we know at that time the mediators we know?" Yi Cheng suddenly shuddered and thought of a possibility that he had never realized before.

"The mediators we are working with were dropped?"
