The red sun slowly climbed above the sea level, shooting out ten thousand rays of light to dispel the night.

Before you know it, the night has passed.

Cui Xiaoxiao sat on the leather chair in the hall, propped her chin with her hand, frowned, and looked at Wei Gong with a bewildered expression.

"So you weren't who you were before? It's a woman named Jiang Liyue? ”

"Uh-huh." Emiya nodded earnestly.

"It's strange to believe you."

"Really!" Emiya said with a serious face, "So whatever I did before was forgivable. Because that body control is not in my hands. ”

"You don't come often, this can't be a reason for you to do strange things and just excuse them!"

"Huh?" Wei Gong was not calm at all at this time, and after thinking about it carefully, he only felt that the hair on his whole body stood up, "So did I do something strange before?" ”

"Strange things?" Cui Xiaoxiao recalled the soft touch on that forehead, and couldn't help but have a touch of crimson on her face.

"It should ...... Well...... Maybe...... Nope......"

She can't tell how she felt at the time, whether it was reality or a dream.

"It's over, that damn madman isn't going to leave anything weird on me, or ......"

Wei Gong ran into his room, then took off his clothes and examined them carefully.

He didn't put his mind at ease until he confirmed that there were no problems.

"Well, I believe you." Cui Xiaoxiao leaned against the door of his room, turned her back to him and hugged her hands to her chest, "If you are not a fine man." ”

It's impossible for the True Guard Palace not to even know what an electric light is, and it is impossible for Kenrin Sakura's expression to be so strange when she hears her name.

It's just one thing that Cui Xiaoxiao can't understand-

The man last night, why did he kiss her forehead, if not a dream?

I don't know why, but at this moment, a trace of loss appeared in her heart, and there was a moment when she hoped that the person last night was Wei Gong herself.

But facts are facts.

Cui Xiaoxiao raised her hand and knocked on the door with her back against the door.

"In that case, let's see what caused it," she lowered her eyes and whispered with her small lips, "if there really is such a thing as a soul." ”

……

Wei Gong closed his eyes and stared, carefully recalled the previous two soul exchange processes, and then opened his eyes and looked at Cui Xiaoxiao seriously.

The atmosphere was serious.

"Okay, you ask."

Cui Xiaoxiao took a deep breath, "How do we usually identify a thing as its own?" ”

"What the hell?"

was ready to accept any of Cui Xiaoxiao's shocking remarks, but she didn't want her to ask a question that couldn't be related to this matter, it was like punching the air with all her strength.

Wei Gong only felt a stagnation in his chest, and rolled two big eyes, "Why can't I grasp the point of your question?" What does this have to do with the special soul exchange that happened to me earlier? ”

"An object, for a certain period of time, has its own unique physical characteristics, and more specifically, its elemental composition and molecular arrangement are constant within a certain time range. You are who you are because your physical features are like this, and your memories are like that. ”

Speaking of this, Cui Xiaoxiao looked excited, and raised Erlang's legs on the chair, swaying back and forth like little white radish.

"So your brain structure determines your memory and your personality, and I just don't understand why the soul would have the same effect."

Emiya thought about it for a moment, "What if the [soul] itself is a carrier of information? When there is an exchange, it is actually the exchange of information between me and the other party, and we have each other's memories. ”

"I also think that [soul] itself has information," Cui Xiaoxiao nodded, and shook her head again, "Then the question is, from the 20th century to the 23rd century, people have been arguing about a topic - what determines the existence of this individual, and if the memory can be transplanted, is it possible that after the new individual has the memories of the old individual, it will become the old individual?" If the soul is the carrier of information, then does it mean that the soul can also be transferred and reproduced? ”

"It's okay to transfer," Emiya smacked his lips in surprise, his eyes almost protruding, "If it's a copy, it's terrible, think about it, there are suddenly a lot more of yourself in this world." ”

So if you use memory to define whether an individual is himself, there will definitely be the situation you said, so later, scientists believed in the existence of souls, because only in this way can they explain the particularity of different individuals with the same memories, even if their memories are the same, but at least the souls are different, so that scientists can let go of the research of memory transplantation without too much ethical and moral pressure.

Although I don't agree with this statement, assuming that the soul exists and can be replicated, then these guys will probably have to crawl out of the coffin when they die. ”

"So the soul is a special being that cannot be copied?"

"Let's think so for now, otherwise it will be difficult for us to have a discussion later." Cui Xiaoxiao took a big sip from the milk cup on the table next to her, "Next question, how are you sure that you and that person named Jiang Liyue have swapped bodies?" ”

"Hmm...... It's hard to say who is inside my body, but I'm pretty sure that the owner of my boarding body is Jiang Liyue, because that's what others call me. Wei Gong recalled what happened yesterday, it was like a nightmare, and to some extent, he also saved Ye Zhao's life.

According to the normal trajectory of time, now Ye Zhao will become a prisoner if he does not die.

"And did you figure out where you were later, I mean when you found out that your body had become a woman?"

As soon as the words came out, Cui Xiaoxiao suddenly remembered something, raised her head, and looked at Wei Gong with a pair of big disdainful eyes, "Should you touch that for the first time...... Right? ”

"That?" Wei Gong knew this, and immediately blushed, "This is something that everyone can do, you have to actually confirm whether it is a dream or not." ”

"It's disgusting."

"You're disgusting, with white liquid on your lips." Emiya took out a tissue from the side and wiped it vigorously on her mouth.

"Emiya!" Cui Xiaoxiao jumped like thunder, covered her sore lips with her hands, and slammed the milk cup on the table angrily.

Her face was flushed like a big apple, but she didn't know if it was because she was angry or because she was shy.
