[Can you spy into my mind?] Yang Qianxi asked tentatively in her heart.

[No, you can't.] I can only analyze the possible thoughts of human beings based on your expression, body temperature, and movements. 】

[That's good.] Yang Qianxi breathed a sigh of relief, she didn't want her thoughts to be known casually, even if she wasn't human, she wouldn't be without secrets.

Yang Qianxi has read countless novels, and when she heard the system, Yang Qianxi's first thought was that she had stepped on shit luck, and with such a golden finger, wouldn't she be able to kill the Quartet in the future. Thinking like this, Yang Qianxi couldn't help but happily ask what "golden fingers" this high-tech has.

[How can the host have such an idea, nothing can be obtained for nothing. 】

It was still the voice of the tablet, but the contempt in it made Yang Qianxi, a former scholar, blush a little. However, if you lose, you don't lose, Yang Qianxi pretended not to hear the system's contempt, and still asked calmly: [But there is no benefit, what do you say I use with you? ] 】

[Didn't I fulfill your wish and take you back to the past.] 】

[Is it really a return to the past?] Yang Qianxi was ecstatic.

[Theoretically it is not possible, but in practice it is also not possible, space and time do not allow two identical life forms to appear at the same point in time, which is against God's rules. 】

Yang Qianxi rolled her eyes, she said just now that she was a high-tech product, and now she is talking about God, which is really inexplicable. Thanks to the benefits of writing books in the past, Yang Qianxi understands many settings. [So where am I now?] Parallel space! 】

[So to speak.] Tianyan scholars' research shows that because of the uncertainty of time and space, there is a bifurcated timeline, just like the bifurcation of a tree. At a certain point in time, for some reason, the timeline forks, creating different spaces in the same context, which is what you call parallel spaces. Their base is the same, but their development is different because of different butterfly roles. Because of these differences, the three thousand worlds and three thousand small worlds mentioned by Buddhism have been derived, and different civilizations with the same background have been derived. 】

So, I still haven't gone back to the past? Yang Qianxi couldn't help but feel a little lost.

[You go back to the past and change, is the future of your existence still the future of the past?] Change is change, as long as you change, your future is not your future, and it doesn't matter what you used to be. Unless you continue to walk the way you used to, that is your true past. But if the process is the same, why do you have to live the same life again? If you change and become that butterfly, the world you live in is a new world. 】

Yang Qianxi didn't understand this truth, but she always had the idea of luck, hoping that she would return to her parents and change all misfortunes. However, she forgot that the moment she lost her breath, she was out of the world of her previous life. Even if this world is exactly the same as when she was five years old in her previous life, as long as she changes, it will no longer be the same world as before. She will go to different universities, she will make different friends, and under her change, she will also have parents and sisters who are completely different from her achievements in her previous life...... So everything would have changed, but she just wanted to make a fool of herself.

But soon Yang Qianxi was relieved, anyway, her family was still her family, and she knew the taste of their souls. As for the difference between the change and the previous life, what does it matter, as long as everyone gets better and better, who wants to think back to the days of the past. Yang Qianxi couldn't help but complain a little that the system explained to her so clearly, without the system's deliberate explanation, she just regarded herself as a reborn at the age of five, anyway, this was originally a rebirth, because everything is the same, the difference is only the path that her family will take in the future.

[Hello, let's officially get to know each other, my name is Yang Qianxi, nicknamed Yue'er, you can call me whatever you want, even the master. Yang Qianxi's love of mischief was committed, and she couldn't help but start teasing the system, [System, what's your name, can't let my system call you, there are so many systems in the world, who knows which one it is called? 】

[Host, my number is XB9624153009, you can call my number.] 】

Numbering? Yang Qianxi's black line, who has nothing to call someone and has to call such a long name, isn't it asking for trouble for yourself. Even those foreigners whose names can circle the earth three times, others also have their own abbreviations, and there is no SB to let people call their full names.

[Forget it, I'll call you Tianyan.] You are from the Tianyan civilization, and you will definitely not be able to go back to that place for a while, so use your name to remember your hometown. 】

No. XB9624153009, the system now known as Tianyan did not speak, and it is estimated that it also acquiesced to this title.

[Okay, my system, tell me about your purpose, I don't believe in pie-in-the-sky. Although Yang Qianxi loves to dream, she never believes in the world in her dreams, let alone in the return of no payout.

[Hello host, I would like to introduce to you the function of this system we designed. I don't know how the system is understood, but I started to introduce the composition of the system, Yang Qianxi doesn't care anyway, so I didn't interrupt the bull's head of the system, and I should listen to the instructions.

Yang Qianxi felt that a flash flashed in people's minds, and she felt that she appeared in a room. With many novel foundations, Yang Qianxi calmly looked at her body, she was still five short figures, but the clothes were cute princess-style puffy skirts, obviously it was not her original body that came into this space, it was estimated that it should be a spiritual body. The room was very clean, there was nothing but a small desk and a small chair. Oh, no, there was a door on the wall facing the desk, and it was pitch black and tightly closed.

Yang Qianxi didn't think about opening the door or anything, and sat on the chair - since Tianyan had prepared a chair for herself, it seemed unreasonable not to sit.

As soon as Yang Qianxi sat down, a robot dog was projected on the desk. Yang Qianxi was stunned for a moment, and then said happily: "Are you Tianyan?" Hello, Tianyan, I'm Yang Qianxi. Ha, I didn't expect your image to be a robot dog. ”

The robot dog nodded and spoke: "Hello host, I am the numbered XB9624153009, and now I am officially renamed Tianyan." Because the host integral is too low and the level of the auxiliary system is too low, there is no physical image, only projection. ”

"Oh, Tianyan, when my points are high, I'll give you a different image of a demon. It is guaranteed to be a big beauty that everyone loves. Yang Qianxi is full of confidence.
