Yesterday An Ran made a bet with Lin Mao, and then lost beautifully. The content of the gambling contract is that he is not allowed to work at the police station......

Listening to An Ran's narration, Wei Li leaned back with a smile.

Wei Li covered her lower abdomen and laughed uncontrollably, "Okay, okay, then you stay at home, I'll go to work." ”

An Ran watched her walk out of the house depressedly, and wondered, why did I demote and become a trainee, but this guy's position is still so big......

Now is not the time to think about this. Enron took out his computer, sat down in a chair, and began his day's work.

The job is for himself.

He was an orphan, and his memories of himself began three years ago on December 21.

That's right, three years ago, December 21, 2012, was the end of the world.

All his memories were after that day, and the memories before that day were just blank.

The first memory, he only remembered that day he was lying in a pool of blood, his consciousness was very blurred, and all he could see was the blood-red sky and black gunsmoke...... The world fell into despair, and so did he.

The person who saved him from despair was a girl. That girl was Ling Rin.

Ling Rin brought him home, and his father, Ling Gu, happened to be a good man, so he took him in during the war. Ling Gu became his father. Ling Rin became his sister.

When Ling Rin found him, he was lying in a pool of blood, on the verge of death, but there was no trace of fear in his eyes, on the contrary, he waited quietly for death, half of his face was wet with blood, but he still seemed very peaceful. So, Ling Rin named him An Ran.

But there's one thing that's strange. The Ling Gu family, who took in An Ran, soon found out that this child didn't like to talk, but that he couldn't speak at all, just like a newborn baby who could only speak some gibberish language. What's even stranger is that a week later, Enron became proficient in Chinese again.

Of course, the oddities don't stop there.

That day, where Ling Rin found Enron, there were two pools of blood. One pool of blood is of course safe, while the other stall does not know whose it is. When the two types of blood were tested, the results were even more surprising, because these two types of DNA do not exist in the world, and they are very similar to human DNA, but they are not human DNA. Some experts explain that this is because Unknown used some weapons with trace amounts of radiation on the day of the end of the day, and Enron was affected by the weapon to mutate the DNA.

There are more strange things. It's just that at that time, there were many wars, and those suspicious things were forgotten one by one, and now, people have completely ignored those things.

But Enron won't forget.

He often recalls his blank memories and thinks about where he came from. Where did you come from? Were you born on the day of the end of the world? Why that day? This and the birth of those monsters...... Is there any connection?

He recorded his thoughts on this computer.

Gradually, he went from thinking about his own origin to thinking about the origin of the unknown. And began to read about it, trying to solve the mystery of his own life from the mystery of the unknown.

Although Enron is not a scientist, because he usually reads this kind of information, he is no less than a scientist in terms of ability in this regard.

After many deductions, he established a bold and absurd hypothesis -

unknown may come from the future, or from the past.

Suppose the unknown comes from the past.

So, the first question, what is the purpose of their timeline from the past to the present?

Although it is theoretically possible to travel from the past to the future, the current technology does not have the technology to travel through time, so how can the more backward past have that kind of technology?

Let's start with the second problem.

From the formation of the ancient earth, gradually to the emergence of single-celled organisms, then to invertebrate multicellular organisms, then from invertebrates to vertebrates, from aquatic to terrestrial, and finally to mammals, and then humans, were born.

Humans know how to use their intelligence to conquer nature, so they stand at the top of the food chain. And the world that can exist now is also the crystallization of human beings and wisdom.

It is precisely because of this kind of thinking that we are unable to see the world for what it really is.

What if humans appeared more than once?

Just like in our current world, if one day all human beings are wiped out. The human era has thus come to an end......

However, billions of years later, or even later, humans appeared again on the earth, and then developed, and buildings were built again, cities appeared again, and a new civilization was formed, and another human era began.

Enron referred to them as the second group of humans.

The second group of humans always has the illusion that they are the first humans to appear on Earth, but in fact, humans have already appeared here.

Now suppose that the humans in our current timeline are the second group of humans, or the third, in short, not the first batch. If the civilization of the previous group of human beings is more developed than that of our current civilization, then it will be possible to travel from the past time to the present, from the past when science and technology were developed to the present when technology is backward.

But there is always a reason for the extinction of the first humans, and that reason can be war, natural disasters, or resource depletion.

If it is resource depletion, then Enron can well explain the purpose of the appearance of unknown.

That's right, to compete for resources.

In order to survive, the first humans began to migrate, to the future.

Their future is the civilization in which Enron is now.

They tentatively sent a group of people, and when that group arrived, they found that there were also a group of humans living here, and they were less civilized than them.

Could it be that they didn't end up dying? If that were the case, then the humans living here now should be more civilized than them, but this is not the case.

Soon they realized something, and Enron came to the same conclusion.

Cornered, they have no choice but to invade.

Then they sent an army of cyborgs to kill all the humans here, and after the empty nests were left, their first humans could swagger and migrate to the second civilized world.

In this way, the first humans completely disappeared into the first civilized world, as if they were extinct. If they don't succeed, they will become extinct because of the depletion of resources, whatever the outcome, the first civilized world will disappear without affecting the historical outcome.

Enron actually knew that this explanation was indeed a bit whimsical, and there were still many problems with this hypothesis.

For example, since the first civilization already had the technology to travel through time, why not migrate to space?

Why send out Unknown one after another? Wouldn't it be more powerful for all the robots to come together to form a mechanical army?

Is there any strategic reason why the first human warriors have not appeared and let the robots attack alone?

In short, there are many problems that can make this hypothesis untenable.

Let's say that the unknown comes from the future.

This is even more troublesome, not to mention that there is no reliable theory that time can travel back in this era, and a time paradox alone is a big problem.

However, just because we can't solve a problem now doesn't mean we can't solve it in the future.

Perhaps the future has solved the time paradox and has a time machine that can travel to the past.

When they (the third group of humans) are also facing the crisis of resource depletion, and for some reason they are not able to migrate to space, so they can only migrate to the past or the future.

Then they chose the past, because the past was known, and they could not foresee the future - the third civilization was so advanced that archaeological techniques could already infer the approximate time of the second civilization.

So they sent out an army of machines. In order to purge the second group of humans and plunder their resources.

So here comes the first question.

Since they knew the time of the second civilization, they must also know the time when the second civilization began, so why didn't they emigrate to the time before the second civilization began? Then they don't need to go to great lengths to slaughter the second group of humans, and they can directly have the most primitive resources.

It's a bit of a contradiction, but when you think about it, it's a no-brainer.

If you were given two pieces of meat, one raw and one cooked, which one would you choose?

Yes, primitive resources are like raw meat, and although you can directly immigrate there without slaughtering the second group of humans, those resources are still untapped, and people have to rebuild their cities. But in the case of a civilized society that has developed to the opposite degree, the situation is different, and people simply drive its original owner out of their homes and move in for themselves. Saves a lot of time for development. It's like a piece of cooked meat, ready to eat when you hold it in your hand.

There are many other problems, some of which can be explained by Enron, and some of which he can't.

The problem in the first hypothesis is still relevant in this hypothesis. In contrast, the two hypotheses are also each other. But in the dark, Enron still believes in the second hypothesis, and even firmly believes in it.

After taking notes, I sorted out a lot of data, and by the way, I calculated the wavelength of the new model of light mecha, and calculated and predicted the time and place of the next space fluctuation. An Ran closed the computer and closed his eyes, a little tired.

He leaned back on his bed, thinking that the day wasn't that long. As for tomorrow...... The corners of his mouth lifted slightly.

……

The next day. Police Department of the Criminal Department.

"A man should keep his promise!" Lin Mao grabbed An Ran's collar and said angrily, "You really dare to come to the police station again with a thick face!" ”

"Wait." An Ran unceremoniously pushed Lin Mao's hand away and said lightly, "Did you misunderstand something?" I didn't break my promise. ”
