With the bell of the end of class, Qi Fan woke up from the desk and touched the pencil case at hand.

She bent down to pick up the pencil case, and by the way, looked at her ankle with valgus again.

Qi Mi is 12 years old and a second-year junior high school student. Twelve-year-old sophomores are ordinary, but in this era of brain-computer interaction, it's rare to see sophomores living in a big city like Beijing who still take the subway five times a day to go to a physical school.

The school that Qi Fan attends now existed before the advent of the era of brain-computer interaction. At that time, there were twelve classes in one grade, and there were about forty students in one class, but now there are only six classes in Qi Mi's grade, and there are seventeen people in the class, and three of them have applied for "online students" because they live far away.

The so-called "online students", that is, people who go to school in the virtual world, are the most common way of education in developed regions in the new era of brain-computer interaction. The invention of the brain-like body and the expansion of the "cloud array" supercomputing unit have enabled the first and second-tier cities across the country to establish a brain-like access network. As long as the brain-like body is connected, people can enter a virtual world that is indistinguishable from the real world, and can experience everything that can be experienced in the real world, and of course, go to school.

So why don't Qi fans go to school in the virtual world of brain-like bodies? To talk about this, we have to start with the development of the brain-like body.

Brain-like bodies were not originally built for brain-computer interaction, as the name suggests, they were originally a neurobiological model for studying the human brain. The invention of the brain-like body was more than eight years ago, when Qi Fan was not yet four years old, and it was originally a fairly marginal project in terms of neurobiological research. The probability of accidents on the fringe projects is relatively high, but it is only because of an accident that people discovered that the brain-like body has the function of storing consciousness, which means that people can connect their brains to it and create a virtual new world in it.

It sounds like a very fascinating discovery, and when the technology really matures, it has indeed taken Asia by storm in a very short period of time. The initial commercialization of the brain-like body was a Sino-Russian cooperation project, and then a new supercomputer was built for this purpose, and the first generation was located in Inner Mongolia, mainly because of the sparsely populated and low electricity prices in Inner Mongolia, which allowed for the construction of a large enough unit. The location of the second generation in eastern Siberia is due to the lower average temperature in the local area, which is conducive to the high-load operation of the second generation units.

But no matter how great the achievements of the brain-like company are, Qi fans will not kneel and lick the big guy like those fans and sisters. Although the classmates in her class chose to go to a physical school by themselves, they also had to make an appointment to play in the virtual world together during the school holidays, but Qi fans have never participated in this kind of activity.

It's not that she's unsociable, it's not that she's "retro", it's mainly because Qi Fan has some kind of special relationship with the brain-like body - she became the first person in the world to enter the brain-like body when she was less than four years old, so she has the highest authority to modify everything at will in the brain-like virtual world.

Qi Fan was told by her parents that this state would cause the brain-like body to interfere with her consciousness, but in fact it was the opposite. With the highest authority, once Qi Fan enters the brain-like body, she can modify everything that has been built in it at will, which is not allowed by the normal operation of the brain-like company. It's really ironic that a twelve-year-old girl has such great ability that the builders of the brain-like company who have at least a doctorate degree can't help it, and they have to guard against her at all times.

However, it stands to reason that if a little girl's consciousness poses such a big threat to the virtual world of the whole country and even Asia and Europe, it can be solved by prohibiting her from connecting to the brain-like body. But no one has the right to take this approach for Qi fans, because she also has an important identity - she is the daughter of the inventor of the brain-like body.

Qi Mi is the daughter of Qi Min, the inventor of the brain-like body, the CTO (chief technology officer) of the brain-like company and one of the three major shareholders, which is why when Qi Min was just a young PI eight years ago, Qi Fan accidentally connected to the brain-like body. To be precise, it was she who first discovered that there was a virtual world in the brain-like body when she was less than four years old. And further, more precisely, that virtual world was originally what she "created" - with her own consciousness. This is also why the brain-like body that has been expanded and expanded based on this has continued the "back door" that is open to her alone.

Because she is the daughter of the majority shareholder of the brain-like company, even if Qi Fan is a threat to the brain-like body, he is not forcibly forbidden to enter the brain-like body. In fact, she could have gone to school in the virtual world, which would have prevented her from walking on her problematic feet. But after experiencing a series of accidents in a virtual primary school, Qi Fan chose to go to a physical middle school by himself.

She didn't want to complicate things and give her mom a headache.

Qi Fan knew that she was not a good child since she was a child, and she broke her leg when she had almost no memory, resulting in her walking with a limp. And she's not the same as an ordinary little girl. When other little girls like to play with dolls, Qi fans like to play with toy guns, pretending to be fighting monsters or "Japanese devils" - this is a concept learned from TV shows, and many people still watched TV at that time. It wasn't until elementary school that she really realized that her mom wasn't a sniper or anything like that, but a scientist who loved to play games.

But no matter what, Qi Fan still supports her mother. She has been thinking many times that if the brain-like company splits and Qi Min can't continue to use the "Cloud Array" supercomputing unit, then she will continue to support her mother and risk the danger to re-establish a new virtual world in the new brain-like body. But it is almost impossible for the brain-like company to split, so Qi fans have never had a chance to prove their determination.

However, Qi Fan also knows that the other two major shareholders of the brain-like company, that is, the other two founders besides Qi Min, are very respectable people. Yelena Andreevna Sakharova is Qi Min's doctoral student classmate and a friend of Ji Yuan, while Professor Zhou Xiaoshan is the predecessor who originally provided Qi Min with a supercomputing platform, and played a decisive role in the expansion of the brain-like body. Qi Fan likes Aunt Lena a bit because she is really good-looking. Professor Zhou, on the other hand, is more like her grandmother.

Speaking of grandma, Qi Mi's grandparents are both engineers and are now retired. She is also half a child raised by her grandfather. However, now, even people of the grandfather's generation have begun to indulge in the virtual world of brain-like bodies on a daily basis, especially the elderly with inconvenient legs and feet prefer to visit the famous attractions that are replicated in the virtual world in equal proportions.

Therefore, as a teenager, it is particularly rare for Qi fans who are not brain-like.
