"I ...... I don't understand. ”

Yan Jingxing grabbed his hair and replied with some annoyance:

"Autumn ...... Uh, Miss Cho-"

"—just call me sister."

Qiu Qimeng said with a smile. Her smile made people's hearts heat slightly, and she couldn't say no words at all.

Yan Jingxing opened his mouth, and at the same time felt the oppressive gaze cast by his fiancée next to him, but he still couldn't resist the charming gaze of his big sister in the end.

“…… Sister Qiu. I have to tell you the truth, I don't know anything about these things, becoming a warrior and getting a body is something that happened in the last month or two, so I don't understand it at all. ”

"Reasonable." The woman bowed slightly, "So, are you two willing to listen to me now?" I'm not a scholar, I'm a warrior, but some of the necessary common sense is understood. ”

For a battle, if there is a huge difference in strength between the two and they know each other, there is no need to pretend on that side; The same is true of knowledge.

The big sister obviously knows more about the body and the alien superpower than them, and there is an absolute gap between the cognitions of the two sides, so it's better to listen honestly than hide it. Even if there is a trap or deception hidden in her words, it can be discerned later.

"Of course." By the time Yan Jingxing figured out this truth, Xie Yuzhi had already responded, "Thank you for being willing to share it with us, please say it." ”

"Very well, then I'll start from scratch."

Qiu Qimeng cleared her throat and changed to a narrative tone full of story:

"In this vast universe, there are two twin planets, which are like mirror images of each other, reflections on the surface of the water, ......"

Yan Jingxing and Xie Yuzhi looked at each other.

This opening sentence naturally made them think of the abandoned palace located on the alien sky for the first time. Through the device in the secret base, they can be transported between Earth and alien planets.

The "superpowers" they possess now are treasures that have been hidden there and have never been discovered.

This matter has not yet been spoken. But if what they expected was not bad, the so-called "twin planets" in Qiu Qimeng's mouth ......

Yan Jingxing began to recall that short but exciting alien journey.

Although they only set foot in a small area, the geography and the plants and animals that grow and move are all very different from the earth.

But that's just from the perspective of the human senses. In fact, even they are vaguely aware; The external environmental conditions of the Earth and the planet over there are very similar, including the atmospheric composition of the earth, which is surprisingly similar - even on the scale of the observable universe, this similarity can still be called a "miracle".

"Rather than simply calling this phenomenon a miracle, the scholars of the committee—ah, where I come from—hope to find out how this miracle came about. Because the connection between the twin planets is far more than an incredible approximation, and there is some kind of ...... between them The special astronomical spectacle, which the Commission's researchers called 'gravity well-canal connection', is by far considered the most convincing hypothesis. ”

Speaking of this, Qiu Qimeng suddenly turned her gaze to Xie Yuzhi.

"Speaking of which, do you know the concept of a 'gravity well'?"

The tone in which she spoke was like a teacher in the school who was earnestly teaching, which made Yan Jingxing feel a little strange.

It would be a shame if the big sister really went to be a teacher, he thought to himself, and the boys sitting in the audience might not have the heart to go to class.

“…… A gravity well is a conceptual model that describes the gravitational field surrounding a celestial body in space. The greater the mass of the celestial body, the deeper the gravity well and the greater the extent of the gravitational field. ”

Miss Xie replied calmly, and the answer was as standard as an encyclopedia.

"That's right! For example, if you put an iron ball on a piece of cloth that is supported, the cloth around the iron ball will naturally sink downward with it as the center; Similarly, massive celestial bodies can create similar depressions in the surrounding space. As you may have heard, the most massive object in the universe is a black hole – a hollow in space created by a black hole that not even light can escape. ”

"And the so-called 'gravitational well-canal connection' can be imagined as a passage between the gravitational fields of the two planets – just as the bottom of the two wells is connected; To put it more figuratively, when we throw a stone into a well, it may emerge from another well. This makes it possible for matter to make a leap between two planets under certain conditions. ”

"It's a spectacle that goes far beyond all the laws of physics that have been discovered so far, because we can't even confirm the existence of that planet, how far apart is it from each other, it could be within the Milky Way, it could be extragalactic? Maybe 100,000 light years? Millions of light years? Or is it more distant, even beyond the confines of the observable universe? Humans cannot grasp this scale. ”

A series of questions and words made Qiu Qimeng's face flush slightly, and she was obviously full of interest in this topic.

"As you may have guessed, one of these twin planets is the Earth at our feet, the home of mankind; The other planet is called the 'Far Star', the 'Star of Bethlehem', the 'Evil Star', the 'Demon Star', and the 'Tai Sui Star'...... There are various names that have been circulated in ancient history. As for now, the people of our committee generally call it 'Alpha', 'Malevolent Alpha'. ”

“…… Wait, 'Ancient History'? ”

Yan Jingxing's eyes widened in surprise.

"Isn't this planet only discovered in modern times?"

When they saw the explorer's diary, they thought—

"Why do you think it's modern? I've never said that. ”

The eldest sister gave him a strange look, but soon, she seemed to realize something, and the corners of her lips rose slightly.

"Ah, I see. You must have been exposed to something related to Alpha, right? Hehe, Jing Xing is really dishonest, what did he say just now that he 'doesn't know anything about things'. ”

“……”

Yan Jingxing obediently closed his mouth.

The eldest lady beside him quietly poked his flank with her elbow, as if to express her dissatisfaction.

But...... You can't blame him for that, right?

The big sister's head turned too fast, and it was really hard not to show her stuffing.

"In short, it is recognized that the impact of Alpha on Earth began long before humans entered modern society; According to the committee's research, this time will continue to move forward significantly. However, according to archaeological records and ancient records, in most cases, ancient people may not have realized that it was the influence of another planet. ”

"As for exactly when the alien planet began to affect Earth, the committee's scientists speculate that it may be further back than human history, even going back between Neanderthals and late Homo sapiens......"

It's big as soon as it comes up.

Yan Jingxing was still a little ignorant of these concepts, but Miss Xie, who was knowledgeable, couldn't help but speak:

"—Wait, Neanderthals to Late Homo sapiens? Pre-Neolithic? ”

This time it was her turn to be surprised.

"That's right."

Qiu Qimeng nodded approvingly.

"In other words, between 300,000 and 800,000 years ago."

After giving the specific figures, even Yan Jingxing could understand it.

A span of hundreds of thousands of years, this is simply unimaginable......

"Isn't that a bit ...... Too exaggerated? ”

Yan Jingxing couldn't help but mutter.

"The body, and the secrets that it holds on that distant planet, are far beyond ordinary people's imagination."

The big sister replied.

"However, what happened to our ancestors in ancient times has little to do with us, so let's start with the beginning that we are familiar with."

"What we do know so far is that there is a civilization on the Malevolent Alpha, just like humans, built by a group of highly developed intelligent races. Moreover, unlike modern humans, who were born only 10,000 years ago, the civilization of the Arfa may have lasted for more than hundreds of thousands of years, and there have been several civilizations destroyed and replaced along the way. They have advanced technology that far surpasses the current level of human beings. Especially in the field of biology and materials science, they invented a technology that we call 'living machinery', and based on it, they created 'bodies'. ”

"This weapon has a natural adaptability to carbon-based intelligent life, and when combined, it can exert amazing power. By the way, as I just said, the body had a huge impact on intelligent life on Earth, and it probably started before the Neolithic period between 300,000 and 800,000 years ago, can you guess where this conclusion begins? ”

“…… Bodies do not arbitrarily combine with any life form, but seek out highly intelligent individuals like the Alpha who produced them. ”

Miss Xie held her chin in one hand and gave a conclusion while thinking.

"I'm afraid the key is how well the brain is developed, right? The brain capacity of early Homo sapiens has actually reached the level of modern humans, and the custom of making clothes out of animal skins, making fire artificially, and burying the dead......"

"—I guessed it right again."

Qiu Qimeng exclaimed.

"It's hard to imagine you're a kid in junior high school. Yes, the influence of the body on human history starts with the 'possession of wisdom'. Hehe, no matter which country it is, there have been all kinds of unsolved mysteries in history that seem to be incredible for a long time, right? Although rare, there are legends all over the world that resemble cultivating the Tao and being otherworldly, just like immortals and gods...... Ahem, the topic is further away. ”

She patted herself on the cheek and continued.

"Whether it's the past history or the current world, the probability of the body appearing in people's field of vision is unusually low. In addition to the limitations of the number of bodies themselves, the criteria for selecting their hosts are equally strict: the emergence of intelligent life on Earth is only a prerequisite for their arrival on Earth, and not every human being can use them. Otherwise, history as we know it may change completely. ”

However, in the nineteenth and twentieth centuries, with the birth of a systematic natural science, the emergence of a scientific community from scratch, and the fact that scientists as professions were no longer attached to philosophical or religious systems, some people began to work on discovering the secrets of the body from history, and went through great pains to excavate the finished product...... It was from this period that the committee we are a member of was established. ”

"Then there's the Big Bang. Two technological revolutions, each discipline has developed by leaps and bounds after the cognitive change of basic science, and the high-level leaders of various countries have launched secret research on the Alpha Star, trying to obtain the secrets of living mechanical technology by reverse engineering the body, and there have been corresponding results——"

The big sister reminded.

"You've seen it already, haven't you? The gang that came with Wu Zhifei. ”

"The ...... A soldier like a werewolf? ”

Yan Jingxing naturally couldn't forget what happened that night.

"That's right. They are the research institutes affiliated with the committee, and they use the genes of the earth's creatures combined with the technology of living machinery to create 'alien beasts'. But, now that you've fought them, you can feel that there's an overwhelming difference in performance between the two—"

"They can't change the world, we can."

Qiu Qimeng opened her palm, and then slowly clenched it.

"The entanglement of the Alpha Malevolent Star, the Body, and human history will continue forever, and the Bodydressers like me and you are holding the power to change history in their hands."
