After a wonderful dream, Emiya is awakened by the sunlight outside the window.

He stretched hard, then opened the door and came out.

Directly opposite, Cui Xiaoxiao's door was still tightly closed.

He looked at the time, it was half past nine in the morning.

How can a child who has been in bed since he was a child grow taller in the future?

Emiya shook his head and went to the bathroom to brush his teeth and wash his face.

I don't know why, today's bathroom is exceptionally clean, as if it has been specially cleaned, and the tiles and mirrors are exceptionally clean and smooth.

He washed his face, hung the towel on the towel rail, and opened the door and came out.

I don't know if it's his delusion, as if the light in the room is much brighter today.

Sunlight filters in through the screen windows on the balcony, illuminating the interior suddenly.

Succulents outside the window are growing just right, and swallows are falling from the sky and jumping around outside.

Emiya noticed that on the balcony there was a food plate with some cereals.

"By the way, I don't see you are getting up. I cleaned it up without permission. ”

Lai Shiyu's voice came from behind.

Emiya turned around and looked at her blankly.

Lai Shiyu wore an apron tied around her waist and a dinner plate in her hand, on which delicate food was arranged.

"Morning." Lai Shiyu smiled sideways, her smile was so sweet that it could melt people's hearts.

"Early."

Emiya laughed wimpedly.

"Since you're up, then come over for dinner, I'll prepare one for you and Cui Xiaoxiao."

As Lai Shiyu spoke, she put the dinner plates on the table one by one.

"Didn't you praise me for my delicious food yesterday, I thought, I don't have anything to repay Lord Weigong, and I have caused you a lot of trouble, so why don't you take advantage of my stay here these days and do my best to make something delicious for everyone." And then while thinking about it, my hands and feet couldn't help but move......"

Yes! Emiya's starry eyes rose.

It feels good to have a woman in the house......

Hey...... This feeling......

Why is it so like a young couple living at home?

No, it can't be, it must be an illusion.

Emiya slapped his face hard.

Lai Shiyu looked at him with a confused expression, to be honest, if it weren't for the mission, she would have really thought about escaping from this place.

An eccentric swordsmith plus a nervous sister who loves gibberish......

Wei Gong sat down at the table, and then took a bite of the food made by Lai Shiyu.

Yes...... It's delicious, so happy, it's like a dream.

He opened his eyes suddenly, then shook his head.

Seeing her work so hard, it seems that I can't slack off.

He finished his breakfast and picked up the plate on the table.

Lai Shiyu watched him bring breakfast into Cui Xiaoxiao's house.

"Don't you know you can't just go into a lady's room?"

Cui Xiaoxiao's voice came from inside the room.

"Okay, what's wrong with serving you breakfast?"

"Okay." Cui Xiaoxiao rubbed her eyes, sat up and leaned on the head of the bed, "You have a conscience." ”

She raised her chopsticks, picked up a small piece of roasted golden steamed bun from her plate, put it in her mouth and took a bite.

"It's obviously not what you did, right?!"

"Shiyu did it."

Cui Xiaoxiao filled the cup with milk and pushed the plate aside.

She looked at Wei Gong coldly, "Say, what do you want me to do?" ”

"It's really worthy of being a doctoral supervisor, and he's very smart."

Emiya sat on the edge of the bed and explained to her, "Isn't Lai Shiyu's sword broken, and Jian Rin Sakura asked me to make a new sword for her." It's just that now I'm running into a little bit of a problem. So need your help. ”

Cui Xiaoxiao bowed her head and was silent.

Well, it would be nice if I could have sent that woman away sooner, although the food she made was really delicious......

"What do you want to know?"

"Is there any way to erase people's memories?"

"What year did you wear it?" Cui Xiaoxiao raised her head and gave him a blank look, "Don't you know that in your time, human beings can be targeted to erase existing memories?" ”

“…… Ay? Emiya's surprise was tantamount to the first time a dead house in a two-dimensional world kissed a girl.

"The first amnestics were discovered by Dutch scientists.

The human brain is a very special structure, but it has some similarities with computers, that is, in the human brain, messages are transmitted and stored through weak electrical signals.

For example, the hard disk of the physical layer is equivalent to the memory storage station of the human brain, and the CPU is equivalent to the analytical thinking mechanism of the human brain.

When a person extracts memories from them, if the process of signal transmission and formation can be changed by electric shock at the right time, the corresponding memory consolidation can be destroyed.

In 2017, around this time, Dutch scientists invented a drug that could be injected to achieve this purpose, and when the patient recalled, the appropriate dose of blocking drugs could successfully interfere with and delete these signals, so that the specified memory was deleted. ”

Cui Xiaoxiao laughed playfully, "If you just want to complete something as simple as deleting your memory, then congratulations, just shock her." ”

“……”

"But electric shocks are cruel and can have side effects."

“……”

"When we really understand memory, a hundred years have passed, the human brain, to be precise, is a three-dimensional organ that can produce high-latitude effects, when people retrieve past memories, the brain will produce a mysterious weak electrical signal, just like the computer uses the key to decode and transfer specific information, this signal can also successfully extract the information generated by the brain, and transmit it to different analytical structures - a specific organ composed of neurons.

Their task is to parse the information and assemble it according to a specific sequence to form an abstract structure at the top level. Then these abstract structures repeat the process just now, get the memory fragments we want, and after submitting them to the screening agency, the memories will 'emerge' to form clear and abstract pattern sound fragments.

That's memory. ”

Speaking of this, Cui Xiaoxiao suddenly fell silent.

The essence of all the advanced computing of computers and the human-like deep thinking that artificial intelligence can produce later is based on the most basic physical structure.

In other words, if your computer is remotely attacked by hackers, the easiest way to block it is to unplug the network cable and turn it off.

If you're afraid that someone will peek at a photo on your hard drive, the roughest way is to smash it.

But......

Cui Xiaoxiao lowered her head and looked at her round little hands in surprise-

Why is it that we are able to transform our bodies, we can change time and space, we can change all the basis on which all memories are based, and still retain all the same memories from the brain of the person who used to be like in a previous life?

Knowledge, experience, emotion, are not diminished, and are perfectly integrated with everything that this body experiences in this world.

Is everything we know about memory wrong?
