"When I first got here, an idea came to me, and everyone showed me if there were any loopholes." Liang Xiao was the first to speak: "The trees here are all abnormally tall, and there are trees of more than 100 meters in our world, but there are trees with an average height of 100 meters, but they absolutely do not exist. There must be some connection between the gigantic tree and the giant...... I guess inside the three walls was a research institute for the study of giant viruses, and they experimented with plants at first, and then slowly turned the subjects into animals...... That's why these plants are so tall that giants have the ability to photosynthesize that only plants have......"

"What a vulgar plot, isn't this the giant version of Resident Evil." Wen Yu pouted: "It's been a long time, it turns out that the giant of "Attack on Titan" plagiarized Resident Evil......"

"Listen to me." Liang Xiao was not in a hurry, and continued to explain his thoughts: "In order to prevent the research subjects from running around, the experimenters built a high wall with the first batch of controllable giant test subjects. Later, I don't know what happened, the virus leaked, and the ordinary people outside the wall also became brainless giants, but inside the wall became a safe place because there were few giants and could be controlled, so people ran in. ”

"It makes sense, but there are still a lot of things that don't make sense, have you ever calculated how big the world is inside the walls?" Zhang Haolin said: "I estimated that the area is equivalent to Qinghai Province, just to do a biochemical experiment, do you need such a large place, do you need to give those experimental subjects a broad free space to ensure that they are happy?" ”

"Well......" Liang Xiao touched his head: "Is it so big?" ”

"So I also had the idea that the giants are not so much predators or natural predators of humans, they are more like killing machines for humans, like a deliberately created weapon." Zhang Haolin said: "My guess is that more than 100 years ago, there was a world war, and then one of the parties developed a biological weapon that can make people giants, which can turn their own soldiers into giants...... And then this biological weapon got out of control, which led to this tragedy, and this wall was built when the situation was not completely out of control. ”

"Ritian's idea can match a sentence in this text on the screen - 'The vast majority of human beings have died, but most of them are caused by human beings', and it is definitely a big war that broke out before this sentence exists." Chen Tao nodded approvingly: "And this can also explain why those intelligent giants hate human beings...... And the royal government wants to kill us. ”

Wen Yu suddenly realized: "Ah-because the humans outside the wall and the humans inside the wall were hostile in that war a hundred years ago!" And we didn't expect this, and pretended to be outsiders in a daze, and it turned out that the investigation corps and the garrison corps with unknown history welcomed us, but the Wang government, which knew the truth of history, would definitely kill us directly! ”

Zhang Haolin's eyes rolled around and found a new question: "But if my conjecture is true, then there are other questions - why does the Wang government hide history, or even destroy history?" Shouldn't the government manipulate public opinion to keep the people hostile to humanity outside the walls to remember the history of the war, but the government inside the walls deliberately wants to erase the past...... Also, since the king inside the wall has the ability to control the giants, why not just go out and completely wipe out the humans outside the wall to prevent future troubles? ”

"There is also the most evil possibility." Liang Xiao said: "At the beginning, someone researched the method of giantization and control of giants, and then wanted to enslave all mankind with this, so he provoked a big war, and then let the rest of the people hide in the wall he built, so that he could rule the human race all over the world." ”

"Like this?" Ming Ye asked in surprise, "In that case, wouldn't the humans outside the wall who have become giants of wisdom be the ones who want to liberate the human race?" ”

"But this line of thinking is not in line with the actual situation - the people outside the wall don't care about the lives of the people inside the wall at all, and the king inside the wall is completely awe-inspiring in the comics that I am for ......the peace and good of all mankind," Zhang Haolin guessed: "So, I made a little change on the basis of Liang Xiao's conjecture to make the conjecture closer to the truth." ”

"Huh?"

――

"First of all, there's one detail that you haven't noticed."

"Don't ask this kind of brainless question, it's okay, there are more details, hurry up." Wen Yu grabbed his arm and shook it a few times, urging dissatisfiedly.

Zhang Haolin pulled back his arm and hugged the other party into his arms, and nodded: "This work was created by the Japanese, I heard that this guy is still a right-wing...... Of course, it doesn't matter to us which wing he is now. It's normal that the people in the anime speak Japanese, but don't you notice that the people in this world don't speak Japanese, but a language that I haven't learned, but that certainly exists on Earth, because I seem to have heard it in the movies. ”

"German." Chen Tao recalled: "The Lord God has given us the ability to understand this language, so we tend to ignore what language the characters use in the plot, but what do you want to say." ”

"I don't know much about Germany, and when I think of this country, my first reaction is 'the country that started a world war', and I'm afraid this is also the subconscious reaction of most people." Zhang Haolin mixed up several previous speculations, and finally came up with a possibility that could explain many questions: "It must be so, at the beginning, there was a world war in the world, and both sides suffered heavy casualties, which corresponds to what the comic book author wrote, 'The vast majority of human beings have died, but most of them are caused by human beings'." Then, a scientist came out and not only made the power of the giant, but also planned to use the power of the giant to make everyone forget the past and stop the war......"

"Mad scientist?" Chen Tao showed a funny expression: "Isn't this the villain image that many Hollywood popcorn blockbusters that only rely on special effects like to create......"

Liang Xiao showed a paused expression: "I understand, unlike the routines of those American movies, in this world, there is no hero to stop that crazy scientist, so he succeeded!" Not only enslaved everyone within the walls, but also erased everyone's memories! ”

"Right...... Of course, we're just calling this guy a mad scientist for the time being, and it's certainly not that simple, and it may even be 'it', 'they' instead of 'him'. Zhang Haolin was a little surprised, it was Liang Xiao who was the first to follow his train of thought: "The crazy scientist's point of view is: technology is evil, and technology leads to war, so he not only caused the disaster of giants, so that the human beings within the wall had to unite under the threat of giants, but also labeled the real history as taboo, but also suppressed the development of science and technology, so that human beings could not completely eliminate the giants, so as to achieve a real 'permanent peace'." ”

Ming Ye showed an expression of admiration: "Awesome, everything makes sense in this way!" ”
