Chapter 50

In this world, time goes by so fast.

Xu Qichen is more and more used to the world. He is used to busy work day after day. He is used to the gags of his colleagues at rest. He is used to reading in class every Friday. He is used to buying drinks for everyone during basketball training on weekends. He is used to listening to Qi Meng's jokes quietly with Xiao Cang.

Habit has every moment of Mu Yao.

I used to feel that I couldn't understand those people who claimed to love each day as the last day.

But now, it seems that he has to be such a person.

When I wake up every morning, the first thing I know is whether the people around me are still there.

If we say that for Lin ran, he is ignorant to like but does not know it, then Mu Yao, is to let him deeply understand the person that his heart is tied to.

But strangely, the figures of these two people often overlap, and even he didn't know why.

What he didn't understand was that.

Why in reality, how can not have a ripple on other people, he ran to his own novel, will really like these characters.

It's ironic.

It's not that I can't fall in love with others any more.

Just like the people, everyone is like you.

"Ye Han, it's raining outside. Do you have an umbrella with you?"

Colleagues let Xu Qichen suddenly recovered, "Oh, is it raining? I don't know. "

"It's not very big. After all, autumn is almost over." Colleagues finishing the desk, said goodbye to him with a smile, "I'm leaving, you also hurry home."

Xu Qichen nodded, "well."

A person was in a daze. When he took the elevator, he thought that he should send a message to Mu Yao to send an umbrella.

Forget it. It's not too bad. Run back.

Out of the elevator, far away to see a tall figure, the street is not bright lights and rain, dense out of the hazy aperture.

Before he could speak, the other party sensed his existence.

He turned around and waved his folding umbrella.

"I'm here to pick you up."

Xu Qichen went over and Mu Yao helped him open the umbrella.

"A fight between us will do."

Mu Yao shook his head and handed him his umbrella. "It's windy today. I'm afraid you'll get drenched." Say oneself again prop open another, two people walk out of company downstairs side by side.

"Let's go out and play tonight."

Hearing Mu Yao's proposal, Xu Qichen was a little strange, but he agreed, "OK."

On the ground deep shallow water, a foot stepped on, bright light broke a ground.

Two people walk silently on the road, one by one umbrella covers of different colors and sizes divide the world into innumerable semi private boxes, each containing different souls.

Mu Yao takes him to a small bar. It's different from the one I've been to before. It's much quieter here. The dim light and the band playing live have a wonderful atmosphere.

Although it's a bar, Mu Yao can't drink. He only ordered a glass of iced lemonade, but Xu Qichen's place is abnormal, which can be regarded as a liquor.

"Recently, I always feel that you are in a bad mood."

Hearing Mu Yao speak tentatively, Xu Qichen doesn't know how to answer the question, so he has to shirk his feeling of not being able to hide to the probability theory who just finished the exam, "ah I didn't do well in the probability theory test last time. " Xu Qichen sipped a sip of wine and sighed, "I always feel that I have worked very hard, but the result is not in line with expectations. Such inequality always makes people feel unwilling."

Mu Yao supported his chin with his hand and reflected the warm light above the card holder in his eyes.

"It seems that I did well in the exam. What do you think is more difficult? "

Xu Qichen thought, "Bayesian Theorem Let's go. "

In fact, it's just a casual reason, and he didn't expect Mu Yao to be a real one. However, as a liberal arts student, he did have some doubts, "I don't understand why the research of artificial intelligence must be based on Bayesian."

"I think Bayesian theorem is very interesting." Mu Yao's fingers gently along with the band's drum beat on the wooden table, "in probability theory, most of the research is positive probability, right?"

Xu Qichen nodded.

From his pocket, Mu Yao took out a bag of assorted fruit candy he had just bought for Xu Qichen. He helped to tear open the bag with his teeth and held it in his hand.

"Suppose I have 30 pieces of sugar in my hand, 15 pieces of strawberry flavor, five pieces of lemon flavor and ten pieces of orange flavor. What's the probability that you can get lemon flavor if you close your eyes and take any one?"

Xu Qichen replied, "one sixth."

Mu Yao said, "this is the simplest case of positive probability, right?"

Xu Qichen smiles and leans his head against the wall to watch Mu Yao."But." Mu Yao put all the sugar back in the bag. "In real life, who would tell us in advance how many pieces of sugar there are and how much each kind of sugar has? The calculation of positive probability, in addition to providing reference samples for unknown things, does not seem to be very practical. "

Mu Yao lowered his head and chose one by one in that small bag.

"That's why we have the inverse probability of Bayes theorem. It's not based on objective values, it's based on subjective assumptions, just like the human brain. " With that, he once again extended his hand to Xu Qichen.

"Close your eyes and take any one from my hand."

Xu Qichen honestly closed his eyes, groped for mu Yao's open palm, and took one at random.

"Open your eyes." The other person's hand held again, "what flavor?"

The Yellow package.

Lemon.

"One more time."

It's another random selection with eyes closed. When you open your eyes, it's still bright yellow candy paper.

Again.

The result of the third time is still the same.

Xu Qichen grabbed Mu Yao's wrist and said with a smile, "is the sugar in your hand lemon?"

Mu Yao spread out his hand, as Xu Qichen thought, a bright golden.

"This is the way of thinking of Bayesian theorem. You don't have any objective evidence. You just rely on the actual results again and again to eliminate the possibility of higher error rate, and then constantly revise the previous judgment." Mu Yao's voice is very soft, which matches the Jazz in the bar.

Suddenly, Xu Qichen nodded and took a sip of wine. "If every math teacher teaches like you, I think I would like math more."

The taste of the wine is too strong. The cold liquid goes down the throat, goes deep into the heart, and then burns a fire. It's extremely contradictory. "However, I didn't know that you were so interested in probability theory. You were sleeping in class."

Mu Yao's eyes looked at the band not far away and murmured.

"Because, I like you, is to follow the process of Bayesian theorem."

Xu Qichen Leng Leng, did not understand his meaning.

"I like you from the first time I see you."

Mu Yao's voice is so deep that it seems to be separated from the surrounding sound. He is in a completely different band and infuses it into Xu Qichen's heart.

"But unilateral liking is like taking candy with your eyes closed. Every time I approach openly, it's a grope in the dark. " He shakes the soda in his glass, and the bubble floats up, clinging to the golden lemon slice

"and your reaction to these actions is the sugar I can only see when I open my eyes."

"When you like someone, you always feel like this. Try to figure out each other's words, even the meaning of punctuation, and try to think out the implication Mu Yao laughed at himself twice, "it sounds stupid, because it seems that everyone expects the active party to be strong and resolute at any time."

He imitated the tone of an outsider, "when you meet someone you like, you should go directly to him. You should tell him that I like you. I just like you, but you have to." With these words, Mu Yao himself all laughed, "but it's himself. How many people will really do that."

Xu Qichen could not say a word.

Almost every word Mu Yao said was beating his heart.

"I don't know what kind of sugar I'll get next, sweet or sour, so I'm careful every time I reach out."

"However, even if I get a lot of them, each one is sweet, but it doesn't represent a 100% probability. I will always revise my judgment and guess if you like me more than I think, but I can never confirm." He splashed the sugar on the table. "Who dares to say that all the sugar is sweet."

Mu Yao looks at Xu Qichen.

In his eyes, Xu Qichen saw himself.

However, unlike Mu Yao, he never extended his hand.

I haven't taken a single sugar.

So his probability is always zero.

"But."

Mu Yao spoke again.

"You liberated me from innumerable attempts and conjectures, and told me the answer directly." Mu Yao smiles and his eyes bend slightly.

"Let me finally stop being trapped in this dead circle."

He was lying on the table, with his long fingers on the table, walking slowly.

Until he grasped Xu Qichen's hand.

"You saved me."

A lot of words in the chest, where wanton noise, but like a bottle of soda opened too long, how can not gush out, can not say.

The only remaining bubbles are surging feebly.The band finished a song and said a few words of thanks.

Mu Yao suddenly stood up.

Xu Qichen took his hand and said, "where are you going?"

Mu Yao laughed, "how can you make me disappear immediately?"

He pointed to the small stage. "Want to hear a song? I'll sing it to you. "

Xu Qichen nodded and watched him step by step onto the stage. He said a few words to the members of the band. Then he sat on the high stool of the lead singer and took the guitar handed to him.

There was applause around him before he spoke.

The yellow top light, from top to bottom, lit his outline inch by inch.

It reminds him of the high school Gala.

Hiding in the corner of their own, it is the same, looking at the person shining.

The guitar began. Mu Yao's voice was low and gentle, just like the tone he used to talk to himself before going to bed.

[dull all day, empty eyes, inexplicable sense of powerlessness. 】

[I feel sick, I feel cold. 】

[there is only one heart left warm. 】

his fingers caressed the guitar strings.

One after another, it seemed to stir his heart.

[maybe Maybe it's a new emotion]

[maybe Who could have infected it. 】

[it could be love. 】

the word "love" was sung by him with a sigh full of fatalism.

Xu Qichen has never heard of this song. He just thinks that the lyrics are so wonderful that every sentence is brought into his heart.

The effect of alcohol began to emerge, and Xu Qichen felt faint dizziness.

Lie on the table and listen to the last sentence quietly.

[maybe All kinds of abnormal phenomena. 】

Mu Yao looks at Xu Qichen's face across the table after table of appreciative eyes.

Because you love me. 】

the last string stopped shaking, Mu Yao said thank you, stood up and went back to the table where Xu Qichen was.

"Do you like it?"

Slightly drunk Xu Qichen lay on the table, nodded, showing a naive smile, "very nice."

Every time he got drunk, he would laugh like a child, "I envy you so much, I can play ball, I have good grades, I sing so well, I feel good at everything."

Just like the person you used to like.

Envy or admiration.

I really want to be such a person.

"None of this is what I'm good at."

Xu Qichen slightly side face, looking at him, "what are you best at?"

Before Mu Yao opened his mouth, he was interrupted by a drunken man. The man staggered and bumped into their table. Half a cup of cold wine in his hand spilled on Xu Qichen's shoulder.

A spirit, Xu Qichen straightened up.

The other side was not clear, "hold, sorry, really sorry ah, I drink too much, sorry, sorry." Then he reached out to help Xu Qichen wipe.

Xu Qichen has been smiling, "it doesn't matter, it doesn't matter."

Mu Yao was a little displeased. He grabbed the man's arm and stopped him, "drink less next time." Then he went to Xu Qichen and took a tissue to wipe his shoulder and back.

When the man walked away, Xu Qichen still kept smiling on his face, but mu Yao was not happy. He helped him sort out the order and took Xu Qichen out of the bar.

Different from the cozy warmth in a small bar, when the wind and rain keep on outside, the chill comes from pushing the door open, straight to the neck.

Mu Yao took off his cowboy coat and put it on Xu Qichen.

Xu Qichen looked at Mu Yao's face and asked with a smile, "why don't you seem too happy?"

Mu Yao grabs Xu Qichen's arm, reaches into his empty sleeve, puts on his clothes, and then buttons him one by one until the last one.

"Don't laugh at people."

Xu Qichen was also very drunk. His voice was not the same as usual. He said with a smile, "why, isn't it good to laugh?"

Mu Yao opened his umbrella and handed it to him, "because I have a small mind and a bad temper. I'm very angry when I see you are so gentle to everyone."

No response.

Two people holding umbrellas went into the rain, like all the people on the street, covered up their inner feelings with umbrellas.

It's like throwing a stone on the surface of the lake. I wanted to float a few times, but it plumped down.

Just when Mu Yao had no expectation, a bubble appeared on the water.

"No way."

Xu Qichen's voice came from the cool night rain.

"What's wrong?" Mu Yao stops and turns over.

Xu Qichen raised his umbrella slightly and looked into his eyes."Wrong words."

His tone, like a serious pupil is judging the wrong type of sentence.

"To be exact, I'm gentle with everyone." There was a look on his face that would only appear when he was haunted by alcohol, naive and seductive.

"But only to you, I am gentle."

What am I best at?

What I'm good at most is loving you for ten years.

What you are good at most is holding my heart for ten years.

Two gray umbrellas come together to create a blind area in the field of vision.

Mu Yao gently hugs Xu Qichen's waist and kisses him under the overlapping umbrella.

Alcohol, night rain, weak light.

Let Xu Qichen's mind become no longer clear.

"Carry me, I can't walk."

Two umbrellas became one. Xu Qichen's head was leaning on Mu Yao's shoulder, shaking, feeling the warmth from his body.

"Cold?" Mu Yao asked.

Xu Qichen shook his head, "not cold." He was like a kitten, with a comfortable sigh, "I really want to spend the winter with you. It must be warm."

Mu Yao walked slowly, thinking that he drank too much.

Xu Qichen talked a lot. He felt that his consciousness was getting worse and worse, and his mind was getting more and more confused. He tried his best to get to Mu Yao's side face, kiss his cool ears, and said the last word in the moment before he got drunk.

"I like you I miss you so much

I miss you before I leave.

Mu Yao tightly pursed his lips, feeling his sharp tiger teeth grinding the inner wall of his mouth, vaguely painful.

The more you get, the more you fear. It's just a fantasy.

Put on a new camouflage, how many more chances of winning? I'm really not sure.

The only thing I can be sure of is that I can do it again and again.

I'll make the same mistake without exception.

Fall into the Bayesian Theorem for you.
