From the decision to move to Chang'an turned out to be a system project, it took more than a year, and in this year, I went back to modern times once, because my nominal father and mother retired. On the issue of returning to the modern era to retire or to recuperate in ancient times, the two had a disagreement, and finally the nominal father won the final victory, and I was forced by them to go back for a comprehensive physical examination.

More than ten years after I left the modern era, I walked into the old man's office and saw the old man who was even older than then, and I forgot what I should call him.

The old man looked at me with a smile of pity, and we looked at each other for a long time, and he finally spoke, "Is there any question to ask me?" ”

"Actually, I've always wondered, why me?"

"Actually, you're part of the experiment." The old man wanted to sit across from me so that I could look him in the eye. He took off his glasses and wiped them with his tie, "You're my student, you should know the subject of our study very well. In fact, your work has long been done, and you have made my theory a reality. ”

"What?" I looked him in the eye and asked hesitantly for a moment.

"The relationship between man and history. We made an assumption that if we knew history, we would not be able to participate in history, or in other words, would we be able to change the direction of history. ”

"I don't really know history, what's more, I have never been involved, and I have never done anything to change history in the past ten years."

"You have done a lot because you know history, so you will unconsciously go in the direction of history, and you have promoted the development of history. What if it doesn't have you? The fate of the samurai family may be different. And have you ever thought about how history has become like that because of you? ”

"What did you say?" I felt like I was going to collapse.

"If you are not convinced that you cannot participate, the wife of the samurai may not die; If Samurai's wife doesn't die, Condensation Frost won't turn into a girl. Then Wu Zetian may not exist at all. Because you are in the martial arts, because you attracted the warriors, so you changed the battle situation of the Xuanwu Gate from a certain situation, if there is no Tang Taizong, then what is the history of the Tang Dynasty? You have always felt that you have not interfered with Wu Meiniang's growth, but you haven't noticed that you and Wu Shi Tong took her as a child to play in the mountains and rivers, you gave her too much independent thinking, and, because you know that she is Wu Zetian, so you are a little afraid of her, and you have contributed to the character development of a generation of empresses. Do you still feel like you're not involved in history? ”

"In that case, the headquarters shouldn't have sent me, and if I don't go, maybe nothing will happen."

"yes, so I just said, I did an experiment, and you're part of it, and you're doing a great job."

"If I don't go back now, what will history be?"

"I don't know, I'm still saying that, history may or may not change because of you, so you decide to go or stay for yourself. Moreover, now you can go to the bookstore and buy any information about Wu Zetian, you can follow the trajectory of history, or you can not follow it. He looked at me with a smile as I slowly digested the meaning of his words, and I think I understood what he meant, that is, that the restrictions that had been imposed on me had been lifted.

"Don't tell me a new experiment has begun, you try to hope that I will change history?"

"I'm 70 years old, and the lab will be handed over to newcomers. And all I can do for you is erase your record. You can go or stay, but if you go back this time, you may never come back. Of course, there will still be people in the Tang Dynasty to support you, your nominal brother, who will replace your parents' mission in the Tang Dynasty, but this is only personal help. ”

"The lab is going to give up on me?"

"Fool, why put a shackle on yourself?" The old man shook his head and sighed, I think I understood what he meant, if he left, he didn't know what the next president would do to Wu Zetian, if he eliminated my information, then what I wanted to do was all my own business, no one would come to investigate, let alone anyone interfere.

I finally chose to go back to Datang, and I decided after an afternoon of stunned sitting in an elegant café in an elegant café and watching the pedestrians on the street. I'm almost forty years old, and when I go back to work in the laboratory, more than ten years of pampered ancient life have already made me lose the ability to survive in modern times, and I can't come back.

Before I came back, my nominal father sent me, I looked at the nominee who was already full of gray hair and was speechless, and the nominal father just patted me lightly on the shoulder, saying that he had already said to his nominal brother, even if the headquarters did not agree, if there was a case, he would send me back. I laughed, I knew there was no such thing as a contingency, now that I was a free man, I would make my own decisions in the rest of my life.
