"Actually... I am not a person from this era, I came from the future era."

Sitting on the bench with cherry blossoms falling, Asahi Shikuru carefully observed Ji Feng's expression from the corners of her eyes, while lowering her voice and telling him his incredible identity.

But what she was disappointed or relieved was that Ji Feng had no reaction at all after hearing the news, as if he had known this would be like this.

"Well... Look, it seems that you have already contacted Asakura classmate Nagato, or you are... In short, I told you my identity at this point in time according to the instructions of the 's superior'.

Then I'll continue talking."

Seeing that Ji Feng was completely indifferent to her words, but just kept looking at her eyes calmly, Shijiru's heart began to panic, but she still suppressed this uneasy mood and made herself try to calmly and clearly continue:

"I can't tell you when and which time plane I came from, and even if I want to say it, I can't say it.

It is absolutely forbidden to convey information about the future to people in the past, so before taking a space-time plane, future people must accept strong spiritual hints. As long as they intend to say something they should not say, the corresponding memory block will be locked."

In the original work, Mikuru seemed to have said the same thing to Ah Xu, but Ah Xu didn't react after hearing it - or there could only be a reaction like "Unclear and sharp" in his mortal head.

However, Ji Feng was different. After all, his mind was much smarter than Ah Xu. In addition, he had been thinking about future people for a long time and had specially asked the information and thoughts about the movement of time. Therefore, Mikuru just said the beginning and immediately interrupted:

"Since you say it is 'what time plane', then there will be more than one time plane in the future, right?

However, on different time planes, different things may happen at the same time point, or in other words, the same person may make different choices for the same thing on different time planes.

So, if these time planes change to a more well-known name, they are called 'parallel world', right?"

"Ah...well, although there are actually differences, you can think so first.

Although time is called the "long river", unlike the constant flowing river water, it is composed of discontinuous time planes - just like cartoons one by one, except that the fracture space between two adjacent planes approaches zero.

If you have heard of the word "energy level", you should know that the possible states of electrons outside the nucleus are discontinuous, and electrons can only move in several specific and separate orbits. The electrons on each orbit have separate energy, and these energy values ​​are "energy level".

In addition to moving on a certain orbit, the same electron can also transition between different orbits. Only when the electron absorbs energy specified by a certain "energy level" can it transition from a low level to a high level.

This is like jumping on the stairs. Only when you have enough strength can you jump up all of a sudden. If you are not strong enough, you will still fall to the spot in the end, and it will not be possible to stay in mid-air. Wait until you have enough strength to jump up.

Similarly, when electrons jump from high energy level to low energy level and radiate photons, the energy lost is also the energy of a whole "energy level", and it is impossible to lose only the little energy jumping down from the steps.

The minimum width of the ‘energy level’ may be the width of the gap in the time plane. The future space-time theory was developed based on this theory of quantum physics. For ordinary people, this should be considered a ‘ban’, but I can tell you, which means that you have learned the basic theory of time movement through some channel.”

Perhaps because Ji Feng had already learned in-depth theories about time movement from the information integration body, Shijiru actually told him many scientific explanations that did not tell A Xu in the original work, and that A Xu could almost understand.

However, so simple, common sense knowledge of quantum physics is as simple as a child's understanding that one plus one equals two. After thinking for a few minutes, he confirmed the theory that Shijiru mentioned and the theory of information integration of the body of thought, and determined the correctness of Shijiru's space-time theory, that is, future people's theory.

In quantum physics, there is a famous experiment that ordinary people may have heard of, that is, the "Schrödinger Cat" experiment. The conclusion of this ideal experiment is that before the box with the cat closed is opened, the cat in the box is in a superposition state of "both dead and alive" until the box is opened for observation.

Of course, as an object in a three-dimensional space, the state of a cat can only be one of the dead and the alive. However, before the box is opened, the box contains not a cat in a three-dimensional space, but two cats in a three-dimensional space. These two three-dimensional spaces are two parallel worlds where the cat dies and the cat lives.

Similarly, every microscopic particle that an athlete follows the rules of quantum physics is equivalent to a box containing Schrödinger's cat. The particle must exist in this box, but its motion is irregular. The sum of the probability of occurrence of points in space is 1. The wave function represents not the real movement trajectory of the particle, but a kind of probability fluctuation, which is the probability density of the particle appearing everywhere in space.

Such a basic small box contains countless parallel worlds, but the limits of these countless equal worlds have been limited - that is, the edge of the box, that is, the limit distance of particle motion.

If a particle obtains energy at an energy level from the outside world, or radiates an energy level photon itself, it will break through the limit distance of movement and jump to a higher or lower energy orbit, which is equivalent to jumping from one box to another box, and there are countless parallel worlds in this box.

And these small boxes with infinite possibilities combined together can form a large box with infinite possibilities to the power of 2. The universe composed of all elementary particles, the total number of parallel worlds is equal to the product of parallel worlds owned by each elementary particle.

This can actually be considered as the number of parallel worlds is endless - because we have not yet explored the end of the universe, which means that we have not even touched the edge of the box, so we naturally cannot determine the size of the box.
