Wang Ke seems to understand whether he understands or not.

Roughly speaking, in another world, his grandfather and grandmother, or his parents, were not united, and there was no him.

In the real world, he exists, and his grandparents, or his parents, exist, change, just a node in another parallel world.

To put it simply, in another parallel world, there will be no appearance of him.

"This situation is achieved on the basis of no additional interference."

Dr. Yuan thought for a while and said, "Your situation is different, through the critical point, you entered the Blue Star two billion years ago, and witnessed everything that happened in the Blue Star, and when you and I described everything that happened, your thinking points were already superimposed on our thinking points!" ”

"Oh!"

Wang Ke roughly understood now: "What do you mean is that our experience is superimposed on your thinking points, or ······ Covers your thinking confirmation points? ”

"Yes, yes, you're so smart!"

Dr. Yuan nodded sincerely: "That's roughly what it means, now, we can only enter the Blue Star according to your thinking confirmation point, otherwise, everything will be different, it will be an unknown and unpredictable situation!" ”

An Ran didn't understand from beginning to end, and at this time he also looked at Wang Ke and asked, "Xiaoke, what do you mean?" ”

"We ······ Woe to you! ”

Wang Ke could only smile bitterly, he didn't know anything about it, and he couldn't explain it clearly with her, so let's say it in a way she can understand: "Since we have been to the same Blue Star, it has disrupted the thinking of Dr. Yuan and others, that is, they can't go back to the time node when they came." ”

"Oh!" An Ran nodded, but he didn't understand it at all!

Wang Keke saw hope, looked at Dr. Yuan and asked, "Dr. Yuan, I will never forget that point in time, I don't know how we can go back?" By the way, how did you get here? ”

"The way we came and the way we wanted to go back is the same!"

Dr. Yuan did not hide what Wang Ke meant: "I developed a field-frequency docking device, which was achieved by tearing apart space-time and creating a critical point of parallel universes through field-frequency resonant docking, and after coming to the relative Earth in the present tense, I found that everything was different, and the field-frequency was much different!" ”

"Oh!"

Wang Ke frowned and said, "There is a problem with your equipment, right?" ”

"Yes, that's what it means!"

Dr. Yuan sighed lightly: "It's hard to go back to the blue star when we came, we can only stay on the earth and debug the equipment, I hope to debug it as soon as possible!" ”

Wang Ke didn't know what the field-frequency docking equipment he was talking about, but he could roughly understand that this set of equipment could artificially create a critical point.

Now that the equipment is broken, there is no way to go back, and I can't save Blue Star, and I can't see Hai Ling again, but fortunately, I still have a thinking confirmation point, so I can only wait for Dr. Yuan to debug the equipment, so I can't be in a hurry!

Then solve the problem of the earth in front of you!

Wang Ke looked at Dr. Yuan and asked, "Dr. Yuan, you said that you know the situation of our earth very well, so what kind of extraterrestrial civilization are we attacking?" And the extraterrestrial civilization that attacked the Blue Star, is it a kind of extraterrestrial civilization? ”

"It's not!"

Dr. Yuan shook his head and said, "The one that attacked our Blue Star, that is, the civilization of the earth two billion years ago, is the intelligent human civilization on the sixth planet of Betelgeuse in Orion!" ”

"Huh?" Wang Ke exclaimed.

If you want to talk about Enron, you may not know much about these, and maybe you don't have any concept of Betelgeuse, but Wang Ke is a top student in the Department of Physics and knows a lot!

Betelgeuse is now a red supergiant, and it is said that there is a possibility of exploding and becoming a supernova, and on its sixth planet, there is an intelligent human civilization, how is it possible?

"Two billion years ago, Betelgeuse in the constellation Orion was not a red giant, but a yellow dwarf similar to the sun, but its lifespan was nearly 9 billion years, and it immediately became a red giant."

Dr. Yuan continued: "At that time, many planets in Orion will be destroyed, and even swallowed by Betelgeuse, the intelligent human civilization on the six stars is quite developed, and they have realized this, and the earth is their first choice, a temporary place to settle!" ”

Wang Ke suddenly woke up!

The blue star that he and An Ran, Li Zhe, and Lei Jian entered was the blue star on the earth two billion years ago, at that time, Betelgeuse was not a red giant, it was a yellow dwarf similar to the sun, and there were many planets, no wonder there were intelligent humans!

If that were to be said, it would not be surprising at all.

In the same galaxy, the earth is a planet in the habitable zone, and they are naturally going to attack humans!

"In the past, there were many, many civilizations destroyed on the earth, and it is different from what you know, and I don't blame you for thinking that two billion years ago, the earth was still in a state where life began to sprout, this is a misconception caused by many other factors."

Dr. Yuan said to Wang Ke: "But the destruction of previous civilizations will cause great disasters to the earth, and it will become a planet that is not suitable for Homo sapiens for many years. ”

"Therefore, they chose a controllable space magnetic bomb, this weapon is extremely powerful, the range is controllable, it can instantly destroy all humans and buildings within the controllable range, and it will not produce any overshooting, and the damage to the environment is very small, as long as it is put into concealment, it is difficult to prevent."

Hearing this, Wang Ke's questions that were not explained by Hailing were basically explained.

I, An Ran, and Li Yu, the moment they boarded the aircraft, saw the rotation on the screen, and finally exploded, and the powerful thing was a controllable space magnetic bomb.

Within a controllable space range, destroy everything, and it will not affect the forest and surface environment, what an advanced weapon!

"It's not the Orion planet that attacked the Earth."

Dr. Yuan frowned and said, "They are the Homo sapiens of a planet in the constellation Libra, and according to the observations of your Earth civilization, in detail, they are the fifth sapiens orbiting around the star 581, Homo sapiens on the planet Gliese 581d. ”

"I know!"

Wang Ke exclaimed: "Libra 581 is also a red dwarf star, known as a small solar system, its mass is only one-third of the sun, and 581d is in the habitable zone, there are really intelligent humans?" ”

"yes, you know a lot!"

Dr. Yuan smiled approvingly: "And the lifespan of 581 is also close to its twilight years, and in a few years, it will also become a red giant, which is also the reason why 581d invaded the human race on earth." ”

Wang Ke now understands that the attack of extraterrestrial civilizations may also be helpless, but their behavior is to invade and occupy to achieve the goal of colonizing the world!
