In the Civilization 4 game, in the introduction to music technology, there is a quote from Shakespeare - if music is the food of love, then go ahead.

He seems to have heard the song Qiao Yiyu is playing now, but he can't remember the name, but this does not prevent him from coming to the living room lightly, sitting down and enjoying it slowly.

Qiao Yiyu turned his head slightly, but the music did not stop, the tactful melody continued over and over again, in the eyes of Han Le, Qiao Yiyu in this state is simply full of BUFF, charm MAX, and the beauty of women is interpreted to the extreme at this moment.

It wasn't until the music disappeared and Qiao Yiyu put the piano away that Han Le barely came back to his senses, but he didn't rush to hide his gaffe, but praised it heartily: "It's really a pleasure to listen to you play the piano." ”

Qiao Yiyu happily accepted this compliment, and then picked up the guitar with a smile: "Why don't you enjoy it for a while?" ”

Han Le nodded: "That's the one just now." ”

Qiao Yiyu changed his posture, changed his posture from facing the window to facing Han Le, played a few strings of scattered notes first, and then officially started.

At the beginning, Han Le faced Qiao Yiyu who was close at hand, and subconsciously felt cramped, whenever the other party's eyes swept over him, he always subconsciously avoided it, but gradually, maybe it was dissolved by the atmosphere of the music, maybe Han Le gradually got used to such a gaze, and he became natural. He began to focus on Qiao Yiyu's two hands playing the piano, on the movements of her delicate fingers, on the changes in the sound of the piano with the movements of the fingers, and on Qiao Yiyu's gaze......

When he finished playing for the second time, Han Le's eyes were glued to Qiao Yiyu's face, and he was almost reluctant to leave, Qiao Yiyu didn't mind Han Le's gaffe, but put the piano aside and made a joke to him: "If I look at you like this, will you think I'm in love with you?" ”

Han Le smiled dryly: "Maybe......" and then shook his head again, "I'm not sure." ”

"Then, let's try," Qiao Yiyu sat next to Han Le, "I have seen such scenes in many movies, a man and a woman look at each other for a long time, it seems that they can fall in love with each other in this way." ”

As soon as Qiao Yiyu sat down, Han Le's calmness just now was thrown out of the clouds, and he was even a little embarrassed: "It's all a blind movie...... The two enemies in the movie are also staring at each other like that. ”

"Just try it," Qiao Yiyu insisted, "Anyway, if you don't say it, I know, you like me, na, I'll give you a chance now, what if I like you when I see it like this?" ”

"Yes," Han Le found that he responded like this in his heart, and even a little impatient, "What if!" Try it! ”

Han Le was like a crappy actor, he took a few deep breaths, and when he raised his head, Qiao Yiyu was already waiting for him, and as soon as the eyes of the two sides touched, Han Le felt as if he had been hypnotized, and all the thoughts in his mind disappeared, leaving only a blank.

In fact, this feeling is not unfamiliar, when Qiao Yiyu showed him the "miracle" for the first time before, it was also in this way, but this time it lasted longer, Qiao Yiyu seemed to have been waiting for when there would be a chemical reaction, Han Le knew as soon as she looked at her eyes that for Qiao Yiyu, this was a look-at-a-glance, even if the distance between the two sides was so close and lasted so long - according to all the novel scripts, even if Qiao Yiyu didn't fall in love with him, at least he would feel a little, But this law has no effect at all on Qiao Yiyu in front of him.

But despite this, Han Le was reluctant to open his eyes half an inch, for him, he simply hoped that this moment could be maintained forever, until the end of the world - but, this was only the idea of his brain, when his neck was sore, and even stiff to the point of numbness because of the support for this weird time, Han Le still had to take the initiative to stop this seemingly romantic behavior.

Qiao Yiyu looked at Han Le, who was grinning, and took the initiative to go over to help him massage his shoulder, and said disappointedly while pressing: "It doesn't seem to have any effect." ”

Han Le was also disappointed, but he was used to being disappointed, but he still wanted to ask for some reason: "You guys...... Didn't people in that era fall in love? ”

"Talk, a lot of people talk," Qiao Yiyu said, "I remember what I said, and we can talk if we want to." ”

Han Le didn't realize the information contained in this sentence, but he was still struggling with the disappointment itself just now: "Then how can you ......?"

"Can you talk about it if you want to?" Qiao Yiyu said, "It's the same way around, if you don't want to talk about it, you won't talk about it." ”

Now Han Le understood, but this understanding then became incredible: "What do you mean...... Does it mean that you can choose to like someone...... No, it can be controlled with subjective consciousness! ”

Qiao Yiyu glanced at Han Le and didn't answer directly, but her eyes told him the answer very clearly-that's it.

"No wonder...... No wonder...... It's incredible, how is this done? Have you discovered the organ in your brain that is responsible for love? ”

"Where did that kind of specialized organ ...... come from," Qiao Yiyu smiled and shook his head, "What's more, what do we do when we are in love...... We're just, you understand it this way, through the synthetic function of the artificial immune system, replacing part of the brain's original work, mainly the dopamine incentive mechanism, so that we are not completely dominated by instinct, just like you did before, depression...... Yes, you also have some artificial bacteria in your body, so I can achieve the same effect with this system. ”

Han Le was stunned for a moment, to be honest, he had imagined the living conditions of human beings in that era that Qiao Yiyu said, or the application of various high-tech to the human body, such as genetic modification, but directly modified the brain...... Simulating part of the brain function is still far beyond his imagination, not that it is unacceptable, but he thinks - this is simply incredible!

"Isn't it scary to hear about brain modification," Qiao Yiyu said, "Many of your science fiction novels have been using this aspect as a negative teaching material." I think people should be completely natural. ”

"No...... No", Han Le replied subconsciously, his mind had not yet recovered from the shock just now, "Natural people may not be perfect...... Oh, it's just imperfect! ...... "Otherwise, where did this world come from so many people who can't control themselves, and if God created man into a perfect creature, why would so many people choose those decisions that they know are wrong, why let a person's mind and instinct conflict, make him sink or suffer."

Qiao Yiyu noticed Han Le's expression, and seemed to feel that what he said was a little more exciting for him, and comforted him a few words: "Actually, it's still not too much...... Well, but, there is a lot less unnecessary trouble, such as depression - this function of the earliest artificial immune system was used to treat depression, and historically, before this technology came out, depression was the disease with the highest mortality rate and the widest range of impact. ”

"Isn't depression a mental illness?" Han Le recalled what the on-campus psychiatrist had told him when he was in college, "Patients need to overcome ...... by themselves"

"It's a mental illness," Qiao Yiyu said, "but the root of psychology is also the brain, depression is like a person who is fired from a company and has no money to live, and this money is dopamine." For a person, this kind of motivation from within the brain is indispensable for a moment, all the subjective initiative of the person revolves around this set of reward mechanisms, which is a physiological mechanism formed in the process of evolution, it is an instinct that people cannot get rid of, psychological problems may explain why he was expelled, help him face the problem, but this does not change the fact that he has no money - this system is equivalent to the bank lending him money, so that he has the motivation to get through the difficulties, but he cannot borrow unrestricted and unconditionally - it is the same as taking drugs. ”

Speaking of drug use, Han Le immediately connected what Qiao Yiyu said with what she said in the square last time, but this time he was not as excited as he was just now, sometimes people are too excited, but they will calm down inexplicably - Han Le is used to this feeling, and this situation can be said to be calm when he is excited, but in normal times, it is a sudden feeling of depression.

This calmness allowed him to return to his normal thinking ability, and Han Le almost immediately realized the huge significance of this difference: "I see, you mean that if people of your time want to fall in love, they only need to adjust this mechanism a little - for example, to fall in love with a specific person, it is easy, just keep looking at his photos and let the dopamine secrete abnormally!" ”

"That's pretty much what it means, but it's not that simple, it's selective," Qiao Yiyu said, "The brain is stimulated too much, and it will produce fatigue similar to drug resistance, which is the same as information overload, and we have a special term in our place, called information control - at the beginning, this control was aimed at the information source, but after the emergence of this system, it was aimed at all direct stimulation of the cerebral cortex." Therefore, there is a limit to a person's daily pleasure, and the average individual can use this system to regulate their behavior, such as being willing to spend more time studying, then allocate more to studying, and if you want to spend more time in love, use it when you are in love - and this stimulation has the highest intensity limit, in fact, compared to you now, our people at that time must be much lower in terms of "average happiness", but our happiness is active and optional, And most people in your time are blind and involuntary in their pursuit of pleasure. ”

"That is to say, if a person aspires to become a scientist from an early age, as long as his parents have been giving positive stimulation in science-related aspects......"

"We are not allowed to do this in our time," Qiao Yiyu shook his head seriously, "All the education process is the same, parents have no right to do this to their children, only after receiving basic education, and when the children become adults, they have the right to decide their own stimulation plan - even if a person does not like to be a doctor, but as long as he has subjective will, he can gradually like being a doctor, which is what it means, in our time, a person who is determined to learn a specific skill can basically succeed, That's how I learned guitar – but in school, similar minor adjustments had to be requested through the teacher. ”

"Then your time is so happy!" Han Le's eyes were full of longing, he could imagine what kind of time it would be - a person can always let himself work in one direction as long as he is willing, which is an absolute happiness in the sense of life for any person - everyone has had ideals, but few can persevere, because most people are ordinary people, and their attention to one thing is often random, affected by some uncontrollable factor inside the brain. But now, this influence has been eliminated, not only eliminated, but transformed into a controllable motivation to move forward towards the dream - as long as this premise is in place, even if it fails in the end due to lack of ability, life is at least fulfilling.

"Maybe," Qiao Yiyu said, "I was able to experience this happiness after coming to this era." ”

"In your time, it is natural to surpass yourself," Han Le's tone of voice was simply jealous, "and each of us inevitably has to bear the natural shackles of our own self, this is really ...... I really feel the urge to hibernate right now, until your time......"

"That's too difficult," Qiao Yiyu said, "and it's not possible now, hibernation is illegal now." ”

"I'm just thinking about it......" Han Le looked at Qiao Yiyu and looked into his eyes like just now, "I finally know why you always say to those suitors that you can't like them, you have such confidence...... We don't have, we can't have, we can't control ourselves to this extent. ”

"I have always felt a little unconvinced, I think that although you are from the future, you are also an ordinary person after all, and I think you ......" Han Le didn't finish his words, and jumped over directly, "Now I understand why, in his superman theory, Nietzsche divides the process of self-transcendence into camels, lions and babies, and most people wander back and forth between camels and lions, of which camel time accounts for the vast majority, but you ...... Naturally a lion. ”

Qiao Yiyu was a little surprised: "I thought you were watching Nietzsche in November at that time......

Han Le fell on the sofa and smiled helplessly, if it was in November, maybe he would still be interested in showing off his philosophical knowledge, but now...... A huge sadness shrouded in his heart - why didn't he live in Qiao Yiyu's time, if that was the case, he would definitely not be like now, he has lived for more than 20 years, and he is still so useless, when he thinks of those thoughts he once had, what kind of stay at home to play games for a lifetime, and live a day by day, Han Le can't help but despise himself - his past life was completely tied by his own self! He wouldn't have been able to break free of this lifestyle even a little, and if it weren't for hibernation, he might have spent his life in front of the computer by now.

"Are you okay," Qiao Yiyu sensed that Han Le's mood was not quite right, "Actually, ......"

"I'm fine," Han Le raised his head, "I just think ...... You should be jealous and hateful, by the way, can you use the method you said, let me learn the guitar? Will this affect you as well? ”

Qiao Yiyu shook his head: "I used to, but now I have eaten this immune system thoroughly, and I can control the part of artificial bacteria in your body alone." ”

Then try it, Han Le picked up the guitar on the side and held it in his hand according to the posture in his memory, he still remembered a little bit of the posture of his right hand, and he didn't know how to put it in his left hand.

Qiao Yiyu helped him adjust his posture, and found him a few books to cushion his feet, and then began to teach him basic fingering, a few basic monophonic exercises, after practicing for about five or six minutes, Han Le began to feel bored like playing the guitar at home before, he glanced at Qiao Yiyu with some doubts: "It doesn't seem to feel anything." ”

"Well, you wait". Qiao Yiyu stood in front of Han Le, stretched out a hand, and gently pressed it on the top of Han Le's head - this posture is particularly similar to a certain religious ritual done by a priest to believers in Christianity - in Han Le's opinion, the relationship between him and Qiao Yiyu is actually very suitable to understand that believers and pastors, Qiao Yiyu is the guide and leader of his life. And here, this action is more authentic than a mere religious ceremony, and at this moment, for Han Le, a miracle appeared.

It's a very similar feeling to the last time, just a little lighter, but I can feel it, it's a faint excitement and fulfillment, this excitement is like when Han Le first came into contact with computer games, the enthusiasm of the whole body was mobilized, in the Internet language of Han Le's era, the whole body seemed to be instilled with a "positive energy", he gently touched the strings, the boring monotony when he practiced just now was swept away, every single note sounded so intoxicating, Han Le had never realized before, The tone of the guitar is so beautiful......

For Han Le, this afternoon is the most fulfilling and unforgettable afternoon he has ever had in his life, although he has not learned much, that is, he can play the "twinkle and twinkle little star", but this feeling of being like a dry sponge, greedily absorbing water, and really keen to learn something is something he has never experienced, or rather, he has never experienced it so strongly - this feeling may have been experienced by everyone when they were in school, but the ignorance of childhood is far different from that of adulthood. Few people will remember the excitement of childhood vividly, but for adults, almost every such experience can be remembered for a lifetime.
