When I opened my eyes, I was greeted by the bamboo ceiling of the Eternal Pavilion and a lone light bulb hanging on it. Pen ~ fun ~ pavilion www.biquge.info should be because of the problem of lighting, this ward seems a little dim, but strangely not gloomy. Ge Yiwei, who was going to arrange his firearms according to the routine of getting up, groped around, but he couldn't find the familiar Type 03 sniper rifle, but instead touched a round thing, well, it felt pretty good......

"Mr. Ge, have you woken up yet?" The low blood sugar after waking up made the voice in Ge Yiwei's ears a little hazy. The movement of his hand still didn't stop, he just touched the thing in a daze, "That, don't touch my head again......"

Five. Four. Three. Two. One.

"Ah, Miss Dongfenggu......" Rubbing his eyes, Ge Yiwei looked at the person sitting on the edge of the bed, "This is ...... In that case, my brother is really dead...... It doesn't matter, he's supposed to be dead anyway......"

"That, Mr. Ge, before you speak," Sanae's voice sounded a little strange, as if it was...... With a hint of reluctance, "Can you stop touching my head just yet...... Although, though it does feel very comfortable......"

“…… Ah, sorry, I woke up with low blood sugar and wasn't very conscious. Withdrawing his hand, Ge Yiwei scratched the back of his head and stared at the ceiling, "I seem to have had a dream just now, a dream that makes people feel very happy but a little sad...... But you have to pick yourself up...... Miss Dongfeng Valley, what kind of love is it now...... Miss Dongfeng Valley?"

"Ge ...... Sir, do you remember? All ...... Do you remember everything?"

"What do you mean?" Looking at Sanae's face that suddenly came up close at hand, Ge Yiwei was startled, and his face was a little red, "Why does your tone sound like I once had amnesia...... Oh, yes, and having something to do with my goddamn dude...... Really, it seems like a lot of trouble to explain......"

"Mr. Ge's brother?ah! That ...... who is already dead" remembered the "impostor" in Reimu's mouth, combined with the abnormal performance of "Ge Yiwei" in the past few days, Sanae immediately guessed the truth of the matter, "Could it be ......?"

"That's it. Ge Yiwei nodded, "A lot of things happened in Mongolia, and as a result, my brother and I swapped identities, and he is the one who has been acting with you in the past few days...... It's really dead, and there was still a glimmer of hope, after all, the doctor's skills are still quite trustworthy...... Forget it, it's all said that it doesn't matter, just let everything pass. ”

"Mr. Ge......"

"Okay, let's not talk about it. Stopping Sanae's words in time, Ge Yiwei began to try to change the subject, "Ah, the boss is asleep too? By the way, did you see Miss Helena and Miss Pache Valley, who must be fighting before I take off my helmet......

“…… Miss Patchouli was so badly injured that she had a large hole in her shoulder, and there was no bone left, and only a little bit of flesh kept her arm from leaving her body. Reizen said that fortunately, the rescue was timely, otherwise it would be difficult for her to survive even if she was a very powerful magician, but it was impossible to restore the function of her left arm. Knowing Ge Yiwei's character, Sanae sighed and replied along with his words, "As for Miss Helena...... It seems that there was a problem with the armor she was wearing, and in the end ......"

"Was it an explosion? Stroking the wound on his abdomen that had been bandaged, Ge Yiwei smiled bitterly, "But where did you just say that Lingxian?"

"Dr. Yonglin...... She has left Gensokyo for some things, and it is estimated that it will be a long time before she returns. ”

"I'm leaving Gensokyo. Hehe, that's right. I understand. Hearing this, the wry smile on Ge Yiwei's face disappeared, and all that was left was a calm face, "What about leaving...... It's a little irresponsible, doctor. ”

"Mr. Ge, Dr. Yonglin, she is not irresponsible, she is just ......"

"I understand. I understand. I get it. If I can really go to the underworld in the future, I will have to see her. Ahem. Coughing lightly, Ge Yiwei continued, "Miss Dongfenggu, please use the one in your hand, that should be a communicator, right?" Inform Miss Yakumo that there are now two spies from the United States in Gensokyo, so let all youkai and goblins be careful." And then...... Although there should be a lot of business to be done...... Alas, Miss Dongfeng Valley, can you talk with me for a while?"

————————————————— Dividing Line———————————————————

"Mr. Alexei, huh? uh, I apologize for what happened to you, but it's just a personal act......"

"I understand. Still moving his wrist, Alexei nodded, "It's normal for people who survive in this situation to be xenophobic, but fortunately, there is still such a ...... Well, artificial intelligence, is it?"

"You don't have to be so rigid about your name, just talk to me like a normal human. Also, I'm sorry, I'm not an aboriginal here, and I'm only recently here. Lin's voice still sounded wilting, "But how to say it, fortunately, they can still listen to what I say." ”

"It's a lucky thing. Alexei glanced at Xingxiong Yongyi, who was standing next to him, and there was a hint of dissatisfaction in his tone, "If anyone could really listen to me, I wouldn't have suffered so many crimes." ”

"Didn't I let you drink my wine? Xingxiong Yongyi waved his hand, obviously not taking this matter to heart. Her mood seems to be better now, "Being able to drink a bowl of wine without getting drunk, sure enough, the amount of human alcohol has improved......"

“…… Alas, since she thinks so, then the matter is over. "And the bowl of wine really doesn't taste bad. Thinking of this, Alexei licked his chapped lips, "Didn't you say that there was going to be an exchange of information? ”

"I think the exchange of information should start with you. What do you want to know now?"

"What do you want to know...... There seems to be a lot of weird things here, but I just want to know one thing. "It's a strange feeling to talk to an AI you can't see. Thinking like this, Alexei said, "What are the bugs, the Nazis, what are they looking for here? Is there really a 'God's legacy' here, and how are they going to be taken away?"

"'God's legacy'...... Hehehe. I'm sorry, but I can't tell you this information just yet. Or should I say, I'm not going to tell anyone. If you insist on asking me, my choice is to wipe you out now. ”

“…… In that case, I don't think I have any other problems. Originally, I was in a state of semi-captivity, and if you didn't give me a chance, I basically couldn't do anything. Hearing the words of **, Alexei spread his hands, "Then, this time it's for you." What do you want to know from me?"

"It's simple. I just want to know if there's any good way to deal with that bunch of bugs on the other side. Lin's voice was suddenly covered with a chill, "Of course, if you hide the information I want to know, I don't mind killing you like this." Also, when your country sends follow-ups here, the youkai here won't welcome them either. ”

“…… It's all threatened to this extent, and I seem to have to say it. Even if it's for the good of Russia. "What a tricky opponent...... Or are you not good at this kind of psychological warfare in the first place?" Indeed, I know how to deal with those bugs, and as long as I find a nest and kill the female, they will fall into chaos...... That's all I know. ”

"The mother worm looks like the other bugs...... Ah, I'm sorry. ”

The other party's sudden apology made Alexei a little confused: "Excuse me......? Are you doing something wrong?"

"Of course. To reassure you, I won't ask you about the appearance of the mother. That way, you have the handle that we have to keep you alive, don't you? Verbal agreements have always been unreliable, unless there is a price to pay for breaking them, and that's the foundation of the basics. "But isn't he supposed to be the one who is more ruthless, right? Sure enough, I've changed after so long...... With a secret sigh in his heart, Lin continued, "So, please go to the lair tomorrow with a few youkai." ”

“…… Thank you for taking care of you. However, you should be able to return my pistol, right? ”

Sure enough, he is not good at psychological warfare? Taking the pistol he put on his own, Alexei thought with some frustration.

"Every time I see the so-called dark energy or light energy in literary works, I can't help but complain in my heart: Do you writers know what the word 'energy' means! In terms of physical definition, energy is an indirectly observed physical quantity, which is often regarded as the ability of one physical system to do work on other physical systems, so who can tell me what the basic definition of dark energy and light energy is? Also, energy refers to the ability of a system, which is a unique attribute of the system, that is to say, this kind of thing must be attached to the system to exist, even if it is a vacuum zero point energy, there must be space there, so how do those protagonists complete the "emitting an energy", "holding an energy in their hands", and "feeling the energy running in the body"? Well, at this point, maybe I'm too biting on the words, the protagonists are actually manipulating the system, but for the sake of literary processing, the description looks like turning energy into a substance, allowing the protagonist to manipulate it...... But can anyone tell me why energy, which is itself an attribute, has attributes? What is light and what is dark, and there is a distinction between good and evil...... Who is going to tell me whether light energy is righteous or evil? What about heat energy? What is even more problematic is why two energies with so-called 'opposite properties' come together to produce an inexplicable reaction? We are talking about energy, not matter! It's hard to imagine what a world where heat and light energy come together and produce other energies would be like, and when light hits an object that is relatively stationary on the body, it suddenly moves?"

It's noisy. Can you be quieter?

"To be honest, sometimes I hate this kind of character of myself, I have to be more serious about everything, and it's really tiring to live like this...... When I first entered Gensokyo, I couldn't sleep all night, there were so many unknowns here, and I had to look for a theory that could be integrated with the existing scientific system. I'm lucky to have the help of Rinnosuke Mori, but I haven't been able to complete this mission until now - my level alone is very limited. Besides, I'm just a student who knows a little bit about physics, and this kind of work is even more difficult for me than to climb to the sky......"

"Don't say that, Mr. Ge, didn't you still understand my abilities?"

"What, figure out your abilities? I guess it's going to be in the next life. All I can say now is that your ancestors passed on to you a fairly sophisticated set of mathematical tools, and I don't even understand that theory now...... I don't have a place to embarrass myself......"

It's noisy. Can you be quieter?

“…… To put it simply, to put it simply. Well, on the number axis, that is, in the one-dimensional coordinate system, we describe that a point above it needs one coordinate, a plane coordinate system, that is, a two-dimensional coordinate system, needs two coordinates, and a spatial coordinate system, and a three-dimensional coordinate system requires three coordinates. By analogy, a four-dimensional coordinate system needs four, a five-dimensional coordinate system needs five, and an N-dimensional coordinate system needs N...... Hey, don't think about what a coordinate system that is more than three dimensions is like, in short, just know that the points on it can be described by the data, that is, a point in the N-dimensional space can be uniquely described by N variables, and conversely, N variables can also be covered by a point in the N-dimensional space, can you understand?"

"Well, if that's all I can understand—Mr. Ge shouldn't underestimate others. ”

"Well, well, don't underestimate you...... Let's put physics in at this point. If we want to describe the state of a particle at moment T, all we need are the position coordinates (x, y, z) and its momentum p. Momentum p is a vector quantity that has components in three dimensions, so it is described with three variables: p1, p2, and p3. So when describing the state of a particle, we use six variables, which are equivalent to a point in six-dimensional space. Then, by analogy, to describe the state of a system composed of two particles at time T, we need twelve variables, which are equivalent to a point in a twelve-dimensional space, and to describe the state of a system composed of N particles at time T, we need N variables, which are equivalent to a point in the phase space, which is called a point in phase space...... Of course, this is not a full meal, and it is much more convenient to describe the motion of a point in phase space mathematically than to describe N points in ordinary space. In classical physics, we use the Hamiltonian equation ......"

"Uh......h Mr. Ge, wait a minute, I'm a little dizzy...... Sure enough, Mr. Ge knows a lot of things......"

“…… I'm already explaining this at the level of popular science, okay, if you get dizzy here, then go to the back to describe the MWI and DH theories - ah, I know, you don't understand! It's the multiverse theory and the decoherent history theory, the latter can be seen as an enhanced version of the former...... Anyway, who made this rice porridge? It tastes pretty good. ”

"Hey you two!" Reimu sat up suddenly, "It's really noisy, don't you know! Can you be quieter! Don't you see that there is still a person sleeping here?"

But God did not fulfill people's wishes, and as soon as he finished saying this, a "gurgling" sound sounded. With a smile on his face, Ge Yiwei raised the bowl to Lingmeng, who was a little flushed: "Yes, pick up your bowl, boss, let's toast!"

"What do you want to do, this thing! Isn't it normal for your stomach to ring when you're hungry? I haven't even eaten breakfast!"

"I didn't say that it was abnormal, I just said let the two of us dry this bowl of rice porridge, and do it first as a respect. After speaking, Ge Yiwei tilted his neck and drank all the remaining rice porridge in the bowl, "That's very good...... But a little thinner would be better. ”

"Ah, does Mr. Ge prefer to drink slightly thinner porridge?"

"Actually, my favorite drink is plain water, but the problem is that it doesn't fill my stomach...... Alas. With a sigh, Ge Yiwei put the bowl on the table next to him, "The boss is also awake...... I guess it's time to get down to business. Sure enough, no matter when, people still have to face reality before they can ...... Thank you, Miss Dongfenggu, for chatting with me, at least I'm in a better mood now...... Boss, if you want to eat, hurry up and eat, there are still a bunch of things waiting for us after eating. ”
