"Just now, I talked about the impact of the 'communicator' on the biological race.

Next, let's talk about the impact of 'changer'.

Still use this clock dial ......," Mio continued.

(The clock dial reverts to its original shape, with 12 numerals in a clockwise circle, and a red hand centered around the center of the dial at the number 12.) ）

"The 'communicator' just mentioned is to put the biological race at a certain point in time when the biological evolution has reached a certain point in time, but the 'changer' is different, the 'changer' is when the biological race has evolved to a certain point in time, and the 'changer' is placed in front of this point in time......

Here are some examples:

When the red pointer, which symbolizes the natural evolution of living things, moves forward to the number 7, there are events within the race that have a greater impact on evolution, which generally refers to bad events.

At this time, if the gatekeeper wants to 'interfere', let the 'changer' appear before the number 7, and if the problem is the number 4, then the gatekeeper will put the cross-over 'changer' at this point in time.

The task of the 'changer', then, is to 'change' the course of biological evolution of the red pointer from the number 4 to the number 7, and thus change the course of civilization that the red pointer originally produced when it reached the number 7.

You can understand what I say.

Okay, if you can understand it, I'll continue......

Now the red pointer is at the number 7 and is still moving forward, and the gatekeeper wants the 'changer' to go back to the number 4 to interfere with the 'past'.

(At this point, at the position of the number 4, a green pointer appears.) ）

Then this 'green' pointer represents the emergence of the 'changer'.

If the biological race uses the 'wisdom' carried by the 'changer', then the civilization with the green pointer will change the original civilization before reaching the number 7, avoiding the crisis that existed in the original timeline.

If the biological race does not pay attention to the 'changer', then the green pointer between the number 4 and the number 7 will not cause a major change to the civilization that the red pointer has already produced, then the civilization represented by the green pointer will slowly integrate into the original time trajectory during the period between 4 and 7, and finally disappear.

The above 'changer' is aimed at the evolution of the entire biological race, and if it is aimed at an individual creature in the race, for example, if they want to go back to the 'past' to save a person, or kill a person, then the effect will be different.

If the number 7 is used to have the 'traverser' go back to the number 4 to save or kill a creature, then the effect will be added to the effect that the creature has had on the entire species and race it has been in for as long as it has been in existence.

However, because it is a return to the past, no matter how much 'interference' is made with individual creatures in the past, it cannot be said that it will not have an impact on the future, because all living beings in the universe, regardless of their level, have their own meaning of existence.

Taking human beings as an example, from this point in time back to before the 'three wars' of human beings, whether it is to 'save' an ordinary person who died before the 'three wars', or to 'kill' an ordinary person who was alive before the 'three wars', although it cannot have an immediate impact on the 'three wars', it will definitely have an impact on the future after the 'three wars', but the impact will not be so strong, because this person's social influence before the 'three wars' will not affect all human society.

But if this person is the 'incumbent' who led the 'three wars' at that time, then going back to the past, whether he 'saves' or 'kills', will directly affect the outcome of the 'three wars' and the development of human society after that.

Therefore, unless there are special circumstances, all gatekeepers of the 'Black Hole Universe' rarely let the 'time-travelers' go back in time to interfere with the evolution of individual creatures in the biological race.

I say this, you can understand.

Therefore, in any way, it is impossible to 'cross' back to save Red Moon, and even if it can, with Red Moon's physique and her willfulness, it will still make things happen again......"

Mio paused, looking at the people in the main building.

"I seem to see what you mean!" Liyue suddenly realized.

"Tell me, if any of you understand, why don't you talk about it for so long." Mio motioned for Liyue to talk about it.

"Based on what you just said, and the demonstration of this clock dial, I guess...... Even if the 'changer' is allowed to travel back to before Miss Red Moon died, even if Miss Red Moon is saved, civilization will not develop, and the green pointer cannot catch up with the red pointer, then the fact that Miss Red Moon died will not change. Liyue seemed to want to organize the language, but she didn't know how to explain it.

"That's one of the reasons, but the main reason is ......."

"Oh! After listening to Xiaoli's words, I also understand more or less, Xiaoling, Xiaoxun and Lingling still don't understand, so I'll explain it to you. Kate asked Mio to take a break, and after saying so much at once, her mouth felt dry when she heard it......

"That's right, you all understand the 'communicator' and the 'changer', and what you don't understand is why you can't save Xiaohonghong, right?" Kate asked the other three.

The three nodded.

"In the case of Xiao Honghong and Miss Hongyue, it should be to let the 'traverser' go back to the time before Hongyue's death, this is clear."

The three nodded.

"If you want to change what has happened, it must be the development of civilization with the participation of 'changers', that is, the green pointer exceeds the original development of the civilization, that is, the red pointer is beyond the red pointer, so that what happens on the red pointer timeline can change.

If there is no way for the 'changer' to participate in the development of civilization beyond the original civilization development, then before the point in time of the occurrence, the civilization of the green pointer will be overshadowed by the original civilization and will not change what has already happened, right? ”

"What does this have to do with saving Miss Hongyue?" Zhen asked.

"Don't you two understand?"

"You mean, a civilization without the participation of the Red Moon will never surpass the civilization with the participation of Miss Red Moon, so at that point in time when Miss Red Moon died, Miss Red Moon will still die? But it doesn't make sense...... "Zhuge Xun always felt that Kate's words seemed to reveal something.

"It seems that Kaoru also understands, I know what you mean by 'it doesn't make sense', I'll explain it later, Ling, do you understand?"

Ling shook her head.

"Then I'll explain it to you in detail." Kate said.
