It's strange that the current dialect suddenly remembered the whining he made towards the sky when he crossed for the third time - "I'm wearing all the clothes, and I'm not allowed to do things?" ”

But now, when something really happened, Fang Yan didn't know how to do it, and even said that his head was a mess......

Graphene, the technology of 2103, is now in 2018.

Two completely different eras and two completely identical technological products have made Fang Yan realize that what he has crossed is the future of his own time and space.

He remembered that during this crossing, someone vaguely seemed to have said something to him - "save civilization".

But at the same time, in the year 2103, mankind has passed the end of the world, and the situation is developing in a good direction, so why should I save it?

Could it be that the future of 2103 will be even more devastating? The seemingly peaceful world is doomed to collapse?

Fang Yan felt that his mind was getting more and more confused, was the purpose of all this to allow himself to change these futures?

But the technology I brought back has turned the future into a "mechanical age", a complete apocalypse, humanity is facing extinction, and that hopeless hope - the Northwest, does it really still exist?

This may be an infinite cycle of cause and effect......

Thinking of this, Fang Yan shook his head, took a deep breath, looked at the blue ocean next to him and asked solemnly, "Who researched the graphene battery, or rather, where is the source of all this technology?" Also, after all this, is there any more advanced technology produced? ”

Two questions, he just wants to determine whether he has been active after June 28, 2017, and then make a judgment based on Blue Ocean's answers.

"In recent years, there have been major events, graphene batteries were developed by the country, and all the technologies in the same year were researched by the country, and more advanced technology will be ...... in the future."

Lan Hai muttered, tilted his head, thought about it carefully, and then replied, "Yes, yes, but they are all derivatives equivalent to the scientific research results in 2018." ”

After speaking, he looked at Fang Yan and smiled, and continued, "Actually, there is no point in asking these questions......

Fang Yan waved his hand, interrupting Lan Hai's next words and falling into his own thoughts.

……

Then, as Professor Huang said, he is a variable, a variable in a four-dimensional space-time, and this variable is not qualitative, random, and cannot be captured in the four-dimensional.

This also means that every time you cross over, you will create a new timeline, just like the previous future was the end of the greenhouse, and the current future is the mechanical age......

He is equivalent to a node on the timeline, constantly changing the time and space of the future.

As for the time, it should be counted from 1 p.m. on the 28th, when he last traveled through, because that was the time when he returned to the modern time and space, just like the beginning of this future, or the beginning of the mechanical age, was at 1 p.m. on April 28, 2017.

And every time I go back, the future will change, just like after I go back from the mechanical age, at 1 pm on July 28, 2017, I will move towards a new future......

On the other hand, if you stop this variable, then there is no way to continue to make changes to the future, but at the same time, what stops crossing is only the "dialect" on this timeline.

Therefore, the "dialect" of this time and space may still be alive in the world, but "he" has not been able to travel since April 28, 2017, and "he" has chosen to contact with the state just like himself, so the country should also know its existence.

No one has contacted, it doesn't matter, it may be because the communication and satellites are all lost, in fact, from the beginning when I heard Zhao Cheng say that the communication and the satellite were lost, he already knew that he would definitely be alone.

"What is the beginning of this mechanical age, you say?" Fang Yan exhaled and slowly calmed down.

It's come to this, it's useless to think about it, maybe your existence is to change the future, and then face a more cruel future, I just hope that I can turn everything in a good direction before the wings of my little butterfly stop stirring.

If you think about it carefully, although your crossing is forced, the time of crossing has been fixed, and the time of stay is also fixed, even if you wear it 12 times a year, then before some people, or the purpose of something is achieved, your crossing will definitely not stop.

Unless, unless, die......

"The science and technology tree is crooked, artificial intelligence is researched by the country, this is for sure." Lan Hai shook his head and continued, "This intelligence should be used for military projects, because the international situation was very tense at that time, and I don't know the rest. ”

"Country?"

"Yes!"

Lan Hai nodded affirmatively, and then continued, "The mechanical reptile can actually vaguely see the shadow of the combat machinery developed by the country in the past, and the intelligence should be used to manage these machines, or to develop better combat machinery, the original intention should be to have strong military strength, increase national defense strength, and deter Xiaoxiao, but now it is not needed, because the whole world is almost the same." ”

Lan Hai spread his hands and said, helpless about these, "Actually, now that you know it, it's not much use, you can't travel to the past, and even if you travel back, you can't change the future of our time and space, right?" ”

Fang Yan didn't nod or shake his head, silently silently silent.

"Let's have a snack." Lan Hai patted Fang Yan's shoulder, revealing a kind of loneliness in his tone, "Thinking too much, it's really no good, I didn't dare to tell them, all this was made by the state." ”

Silence began to diffuse between the two, the sun in the sky was still shining, but this earth was already unrecognizable.

"Don't say anything, I'll follow them back and pack my things!" Lan Hai shook his head, turned around and followed the crowd, and then suddenly turned back and shouted at Fang Yan, "Thinking too much, it's not beneficial, this era is not our era, the heart must be wide, the body can't be fat, and one is counted as one!" ”

Hearing this, the people walking around looked over, looked at the blue sea, turned their heads silently, and continued to walk towards the original camp.

It's true that this is not my time, but it is a time that I have created......

Fang Yan shook his head, smiled bitterly, and turned his head to walk in the direction of Zhao Cheng.

This is equivalent to a causal relationship, where there is a cause and there is an effect, and then from this "effect" the next "cause" is triggered, and so on and so forth.

The dialect doesn't know if what he thinks is wrong, maybe something is wrong, maybe something is right, but all this can only be answered in the future, when this cycle of cause and effect stops and he stops traversing.

And all this is premised on that he can live......
