What is Happiness? If God gives you another chance, and you are still willing to live the same life and do the same thing, then it is called happiness.

Such a topic is completely incomprehensible and heavy for a child who is only four years old. However, the mind of this little boy who had just learned to walk for various reasons kept thinking about three questions that were deeper and more complex than this one.

Who am I?

Where am I from?

Where am I going?

The little boy's name in his parents' hearts is Yin Hyun. His father was an ordinary blue-collar worker who worked for a car manufacturing company in one of South Korea's industrial conglomerates in Ulsan, and his mother was a semi-housewife who only worked a similar part-time job in a flower shop not far from his home. Yoon Hyun is their second child. Even according to the strange way of calculating age in South Korea, for this four-year-old child who has just learned to walk, the parents are a little worried about the future character and body of this child who does not seem to be lively at all and does not cry.

However, this little guy who is thinking about the three major problems of Socrates has another name of his own in his heart. Su Xiubin. A slightly delicate Chinese name. A name that accompanied the memory awakened by the first cry that came out of his mother's womb, along with this name, many memories also flooded into his brain.

And then in the next three years, he was often in a state of memory overflow, or changing words, crashing, and kept looking at the memories that he didn't know if they belonged to him or not.

Or maybe it's just a dream.

In that dream, he was a Ph.D. student majoring in philosophy from a well-known university in China, but unfortunately, in his thirty years of life, he never left the city with rings and rings. Born and raised in Si, if it weren't even for the unquenchable electric fire in the last moment of memory, there is a high probability that he will be an otaku who is old.

Yes, otaku. The loneliness brought about by a single-parent family made him the biggest habit of locking himself in a small room where no one was around, quietly watching TV, reading books, or thinking about all kinds of strange questions in his mind. His father, the only thing he could rely on, would come home once in a while, throw him the money he had barely enough to make ends meet, and then hurry out and disappear. After he was in junior high school, the irresponsible father never appeared again. In order to make a living, he can only work in a small restaurant not far from his home. Fortunately, the restaurant owner who looked stern-looking was a very gentle person, not only took care of the food, but also did not squeeze him. And he doesn't seem to have any friends other than the boss.

Such isolation and autism make him very special in school. And when he ranked at the top of various exams again and again with excellent results, this kind of isolation became unsociable arrogance in the eyes of others. But Su Xiubin in this memory has always guarded this loneliness, not explaining, not covering up.

It was not until he was successfully admitted to the university that almost all Chinese dreamed of, that something born with the exhibition of the times slowly opened a crack in his heart as hard as steel.

That stuff is called a network.

Unlike the withdrawn in reality, in the network, he is an active wise man. The unparalleled amount of reading brought about by perennial loneliness, and the smooth writing formed by being accustomed to self-talking, seemed unusually dazzling in the era when the Internet was just born, and you would never know if you were sitting across from your computer or not.

The gap between reality and illusion is so gorgeous that people can't extricate themselves at all.

Su Xiubin naturally loved this feeling to death. So when he was admitted to the graduate school of philosophy, then a doctor of philosophy. Just so that I can continue to nest in the school and ignore what is going on outside the window.

Of course, this deaf thing outside the window is not something outside the window in the real sense. You must know that he can be regarded as the first batch of people in China to contact the Internet, from the various chat rooms and forums in the early days of the Internet, to the portals that gradually appeared, and then the gorgeous turn of search engines, and then the mobile Internet with the arrival of Qiao's gang leader, this person who has been on the Internet almost all day knows far more than others.

The more you know, the more you naturally understand, especially in the various novels that flash in his memory from time to time in the so-called "online text" genre that he thought he was a friend, he clearly told him that this is a mainstream way of rebirth and crossing. However, fiction is one thing, and when this thing is really born, that is another thing.

Especially, when this is the head of a Ph.D. student in the Department of Philosophy who has already saved up enough for his graduation thesis at a well-known university and is ready to apply for graduation, this memory that may have been digested in a month is no longer so simple, not to mention that in the memory of a few minutes before the spark flashed, he was entrusted by a long-time friend of God to test a new wearable electronic product.

A strong sense of Inception and the Matrix came to my face. Then he began to constantly examine the reality of the space in which he lived, and then began to wonder if he was dreaming, and began to wonder if he was framed by a friend and entered the secondary matrix...... If it weren't for his current physical limitations, he might have really wanted to try the way he woke up from a dream in Inception.

It wasn't until the real pain during the injection not long ago that he realized that it was definitely not a dream.

But this did not affect him from constantly asking himself those three questions in his constant self-examination.

Of course, as an otaku who used to study and soak in the Internet, he could have played the role of his newborn baby very well, but the various discomforts caused by the memories he acquired have always blocked his dream of becoming a baby.

For example, it wasn't until the third day of his life that he finally accepted breastfeeding...... Then in order to get him used to the bottle, it was used for another month...... And then there's the crawl that can't be done well anyway...... And then how to walk and how to wrestle the toddler......

What's even more terrifying is that he can't understand what the people around him are saying at all. It's just that from the various Korean variety shows I watched in my previous life, I was sure that this was a Korean language. But I don't know why, simple words like mom and dad that I have worked so hard to learn don't come out anyway.

This kind of embarrassing feeling of "I know but I can't say it" is really terrible.

In this sad frustration, he slowly lived to his current age, 4 years old.

Speaking of which, Su so-bin, oh, or we'd better call him Yoon Hyun. Yoon Hyun is really a little speechless about the age calculation method in South Korea. Because he was born around the time of the Spring Festival, a traditional Chinese festival, he is inexplicably now 4 years old. But he swore that he had only had two birthdays. On his second birthday, when his mother and sister appeared with a birthday cake with "4" written on it, his crying and laughing face showed an unspeakable sadness: he was 33 years old, but he was still struggling with the question of whether he was 2 or 4 years old.

Although the influx of a large number of memories has inhibited Yin Xian's ability to learn languages in a certain way, as a Celestial Empire student who can learn English well in an environment where he has no contact with foreigners for many years of exam-taking education, learning a Korean language that claims to be the most scientific language in the world, but is actually born in a large number of Chinese, is not a difficult thing for Yin Xian. When he showed his interest in learning languages by selling cuteness, his mother, who had successfully raised a daughter to a rebellious period, began to enlighten Yin Xian with a familiar way.

This kind of babbling experience is actually only once in a lifetime for everyone. And this experience often does not exist in my memory, and I can only vaguely see the shadow of my own year from my own children. But Yoon Hyun was indeed lucky and unfortunate to experience it twice.

What's more unfortunate is that the native BJ man in his memory, for the fluency of Chinese, the tone change has become a solid obstacle for him to learn to speak at this moment. In order to overcome this habit, he practiced almost every day from the beginning of learning to speak until he reported to elementary school.

Time slipped away as he kept fighting with the memories in his mind and the curling of his tongue.

Finally, this guy who doesn't know what his situation is, has reached the age of going to school.

In school, after studying, Yin Xian slowly knew the situation he was in now. There seems to be a little ...... The unreality of science fiction. The history and culture of this place he came to are exactly the same as his previous life, and even the language seems to be no different, but the complete similarity in these details cannot hide the big difference in the overall situation.

He knew that when he was in this place now, or when this planet was not called Earth, his mind couldn't turn for a long time.

Obviously, everyone is almost the same, why is there such a difference......

Then he remembered the memory...... Oh, or it can be called a past life, when I was a graduate student in school, the student in the dormitory, who claimed to be the rising star of physics, gave himself the set of string theory in the so-called cosmology of popular science while chatting.

As a philosopher, it was a bit reluctant for him to understand a large number of equations, but that didn't affect his understanding of the theories instilled in him by his roommate.

In the cosmology that his roommate instilled in him, each solution of the equation corresponds to a universe that exists. This is the so-called parallel universe theory...... The imaginary solution, on the other hand, is most likely a universe composed of immaterial, that is, the so-called spiritual world......

At that time, Yin Xian was only able to understand the possibility of his existence in theory, although he was skeptical and critical of the solution of imaginary numbers, and the two quarreled for a while. But now it seems that he has proved the correctness of this theory with his own life.

Fortunately, even if this is a parallel universe, it is at least a material world......

With the most powerful attribute in the otaku gene, "what comes is safe", Yin Xian only spent half a year in the first grade of elementary school to accept that he came to a parallel universe and will continue to live here.

Then, he also felt that this setting was quite emotional.

If that buddy of his friends knew that he had come to such a strange place, he would definitely scream with excitement...... It's just that I may never see him again, so it is impossible to tell him the news......

He still owes me 200 dollars......
