He Jun thought that he was having auditory hallucinations, but he suddenly found that Lei Yu's expression was not quite right, and a shocked light appeared in his eyes, and he subconsciously asked, "Did you hear it too?" ”

Lei Yu's expression was unusually solemn, and he nodded heavily.

It was just a matter of talking, and the roar from the horizon had become very obvious, and the survivors who were busy dividing the flesh froze one after another, and one after another looked up at the sky, dozens or hundreds of eyes searching the entire sky like radar.

"Where!" I don't know who shouted in surprise, and pointed diagonally to the northeast sky with one arm.

Everyone's eyes moved to the direction of the finger of the arm at the same time, a bright spot in the air became more and more obvious, He Jun looked at Lei Yu in shock, and the two shouted three words in unison: "Helicopter!" ”

That's right, helicopters!

He Jun's mind was in a mess, he never thought that he would still see helicopters in his lifetime, this kind of crystallization from the modern cutting-edge industrial system, and he couldn't help but have a question in his heart, where did the helicopter come from?

Could it be that these buildings did not pass through, but through other parts of the city?

This idea was denied by He Jun himself as soon as it came out, if the community is still at the right point in time, then how to explain that the time of the day has become twenty-two hours? How to explain the strange starry sky at night?

It is an undeniable fact that the community crosses, so the origin of the helicopter is about to come out, and eighty percent of it has traveled to the prehistoric era like the community.

But He Jun really can't believe this answer, the community crossing can also be explained by time storms or other natural phenomena that humans don't yet understand, if there are other places and communities that travel through the prehistoric era together, how to explain it?

The entire Earth has entered the Age of Time Traveling overnight?

This joke is not funny at all!

He Jun does not have a huge mind for the world, but he knows very well that large-scale time chaos will bring disastrous consequences, and any change at a certain point in time may change the direction of history beyond recognition!

This is by no means unfounded, to use the simplest analogy, if human beings pass through the prehistoric era on a large scale, as long as the population base is sufficient, it is inevitable to use natural resources to industrialize and modernize in the prehistoric era, and industrialization will bring extremely strong natural pollution, extinction of a large number of prehistoric organisms, in case the ancestors of mammals are extinct, how will future generations of human beings evolve?

Some people may say that human beings can reproduce from prehistoric times to future generations, but is it so simple to calculate a long time of tens of millions of years?

Any ice age, what meteorite hit the earth, what coal burning incident, any global natural disaster may strangle human civilization.

The butterfly effect is the best explanation for causality.

Some people may say that if history is changed, space will bifurcate and become two equal worlds that do not interfere with each other, one continuing the original history and the other a new history.

But, is this possible? Not to mention the ethereal speculation that parallel space is inherently illusory, even if parallel space really exists, will the universe split into unrelated twins because of a small change on the earth?

According to this theory, He Jun just spits a mouthful of phlegm, and the world will be split into two universes, spitting and non-spitting!

Isn't that? In this way, the universe is splitting all the time, so how many parallel universes should there be?

A universe, a single line of time flow, any change may affect the direction of history, is the most likely situation!

He Jun couldn't help but be shocked, he alone slaughtered two giant beasts, a scaleless crocodile and a prehistoric giant frog in prehistoric times, causing an impact far beyond the scope of a butterfly.

Will this qiē have an irreparable impact on future generations?

After all, you can't just let the survivors do nothing and wait to die just because they are afraid of the effects of the butterfly effect, right? He can't do it himself, and he doesn't even have to ask what others choose.

He Jun can only hope that the butterfly effect is not as exaggerated as in the movie!

However, after thinking about it, he felt that he was a bit redundant, and if the survivors really affected the course of history, then human beings should not appear, so as to deduce the result that all the survivors did not exist.

However, after so many days, I have not heard of a single survivor who suddenly disappeared, thus proving that the activities of the survivors did not affect the course of history!

In other words, this qiē is a part of history, but it has been submerged in layers of time for a long time, and no one knows about it.

Thinking of this, he finally cleared out his chaotic thoughts and smiled with relief.

Lei Yu asked curiously, "What's the matter with you?" A blue and a white face? ”

"It's fine!" He Jun smiled on his face, "There are some things I want to do, we can do whatever we need to do in the future, and we don't need to worry about superfluous things." ”

Lei Yu was puzzled for a while: "No, why can't I understand what you say?" ”

At this time, the helicopter had already flown to the vicinity of the community, circled around the community twice, and hovered above the community square, which meant that it was going to land on the community square.

He Jun's smile became brighter and brighter: "The plane has arrived, I'll explain to you when I'm free!" "Then he ran to the community square.

Lei Yu stretched out his hand and wanted to drag He Jun back, but He Jun's movements were about to go out of the line, Lei Yu grabbed the air, hated so much that the roots of his teeth itched, and he pinched his waist with both hands and shouted: "Is there such an appetite as you?" ”

Just as Luo Jiaqi walked out of the unit door with a plastic basin filled with half a basin of water, he looked at He Jun, who was striding away, and then looked at the helicopter hovering in the sky, looking at a loss.

Lei Yu glared at him angrily: "Why are you still stunned?" Put the water there first, and then talk about it later. ”

"Oh!" Luo Jiaqi hurriedly put the basin by the door, and chased after He Jun like a dog and a rabbit.

Lei Yu smacked his lips tastelessly and walked unhurriedly towards the community square.

It takes a little time for the helicopter to hover from hovering to landing, whether it is suspended in mid-air or falling to the ground, before the rotor stops, the wind under the helicopter is more than ten or more, and it runs over to eat ash with a roar?

However, there were really few people who knew this, except for a few people in the convoy near the lake who volunteered to stay, the rest of the survivors flocked to the community square, and even threw aside the meat that had just arrived.

Walking in the crowd, Lei Yu is completely different!

As Lei Yu expected, He Jun ran to the edge of the square, but was blown away by the wind and couldn't move any further, so he had to stop there and wait for the helicopter to land.
