"Every life should have a past, because the past is worth recalling and learning, it enriches our minds, expands our imagination, cleanses our hearts, I can't imagine what a race without history will become, just as once we deny the memories of the past lives left by these cybermen, what a crazy thought it will be, lose those precious footprints of humanity step by step out of the mud? Is it a denial that we believe in all the truths of the past because of the fault? You see, it is the past left by the cyber people that fills our broken souls, and the past has shaped everything we are today, and it has contributed to the entire process of human civilization. ”

"But what if it's all just a lie from the cybers?" A male senior student in the Philosophy Building in the front row said suddenly.

"Lies? Are you saying that all these great discoveries, theories, arts, and dreams were invented and forced into us by cybermen? It's simply ...... "Luna. Sorkins struggled to hold back the word 'ridiculous'.

"Theoretically, as the embodiment of deception and lies, playing with the human mind is their specialty, and from trying to enslave us forever, cybermen obviously have a myriad of motives for doing so......" Another girl in the front row also unabashedly expressed a strong hatred for cybermen.

"After landing, the cyber people can make up our genes and let us resonate with these things they 'created' according to their arrangement, and in order to make a lie, they just have some 'superficial' truth mixed into it......" The girl began to wave her arms feverishly.

"You mean 'shallow'? That's all the truth and philosophy of this world. This time Luna hadn't spoken, and there were other students in the classroom who couldn't help it.

"At least from my understanding, gravity and relativity are superficial scientific knowledge that cybermen can discover and compile into the so-called history created for us, and then organize it into a big lie!" The senior boy who first questioned Luna said loudly.

"If cyber people are so unbearable to discover 'superficial' knowledge, why haven't you found anything?" In the corner of the classroom, someone suddenly sneered calmly after he finished speaking.

"First, I'm not a cyberman, and second, they've already found out, so how can I find out?" The senior blushed and forced.

"It turned out to be a muddy person." The student in the corner was teasing and teasing, causing many students in the classroom to laugh, but the teacher Titanis had no intention of interrupting, and he seemed to let the argument of this round of discussion develop to this point.

"Well, of course all kinds of opinions are allowed in my class." The Doctor finally spoke.

"But maybe there are some topics that are too 'science fiction' that shouldn't be included." The Titanis seemed to be laughing too, and the senior student of the Philosophy Building had to hide his blushing face in the holographic courseware.

……

“…… In a sense, there is an indelible fault in our development process, which seems to be irreparable, so it will become inappropriate to look at the past, so we can only linger on 'destruction', and the future is 'survival'...... Hmmm, Jonny. Kent, that's an unfamiliar name, do you have anything to say? Kent classmates? ”

In the corner of the classroom, Jonny released the touch button on the holographic screen to speak, put the panel away, and then stood up, he heard someone next to him chuckle before he realized that something was wrong, and he never seemed to be able to break the habit of standing up and speaking.

"Dr. Titanis." He still stood straight and respected.

"Is it true that the past cannot be recovered? I mean, it's clear that we recognize and support this history as a whole, don't we? But why not want to discover more for hundreds of years? ”

"I was surprised that these words came out of the mouth of a non-'muddy person.'" The Titanis smiled, standing in the center of the classroom, and could naturally distinguish the source of the sarcastic voice just now.

"Do you mean excavation? From where? Where are the cybermen? If they still exist, of course. He replied to Jonny.

"But...... Cyberman ...... Maybe they're really gone, and apparently they didn't create humanity, so can't we really go back to the roots? Find the place where all truth originates? Exposed by the Titanis in public, the anonymous Jonny's tone was a little weak, but he still insisted on asking the star teacher the question that had existed in his heart for a long time, and the Titanis's answer surprised him.

"You mean 'Earth'?" Romong. The Titanis said suddenly, and those two words made Jonny shake like a lightning strike.

"Earth...... How do you ......" he spoke almost incoherently.

"That's the name, I think ......" The Titanis tilted his head to search for the memories in his head.

"Although the term gradually died out after the 'Cyber War', if you have enough professional authority to refer to some documents published in the early years, the word is actually not unfamiliar, yes, the earth, in the legacy left by the cyber people, it represents the name of our ancient homeland." As a former famous scholar in Xuesi City, and now the biggest star teacher of Newton High School, the Titanis naturally had or had the privilege of browsing high-security documents.

"Then why don't we look for our past home...... I mean, this earth? Jonny was a little excited, the past and the future, the cause and the purpose, there were too many secrets hidden in his heart, and he needed more answers and explanations.

"Where to look? Where is it? There is nothing left in the cyber legacy that would allow us to retrace the past. And judging from the countless galaxies and planets that humans have explored for hundreds of years, there is no indication of its existence. ”

"Maybe ......," Jonny resisted the urge in his heart.

"Maybe she's not in any galaxy we've explored...... I mean, maybe on the other side of the galaxy...... "in another spiral arm, where, in the solar system, he screamed in his heart."

"The other side of the galaxy? Yours think almost the same way as the imaginative astronomers, Mr. Kent. Titanis smiled.

"You must know that with the top scientific research strength of the Silver Alliance, even if it is using the miniature star cave technology of the Disfaradoo people, it will take thousands of years for our spacecraft to reach the other side of the galaxy, and this distant discovery is not something you and I can see."

"What if...... Dr. Titanis...... I mean, if Earth is on the other side of the galaxy and we end up here, how did the cybermen get the starship? Jonny asked.

"First of all, don't deny your false if, assuming that this is really the case, because cybermen have infinite life, they can sail for thousands of years to reach the Martial Emperor Galaxy, no matter what, they succeeded, didn't they? Otherwise, there would be no such dialogue between us. ”

"Where's the stargate? Maybe there will be a stargate that will reach directly on the other side of the galaxy......" Jonny threw his final killer move.

"In that case, we should have discovered it a long time ago, you must understand, maybe it is the creation of people, the galaxy is only our side of the spiral arm has various stargates, and all known discoveries have proved this theory."

"I think you've forgotten the most important thing, Kent." It was close to the end of class, and the teacher's alarm clock in Titanis's heart was already counting the seconds.

"It was destruction that led to rebirth, and perhaps our former home is long gone, and we were born here, not Earth, which is already an excellent argument."

"The term earth is a thing of the past." The doctor finally summed up to his inquisitive student before announcing the end of class.
