7 hours ago. Edison, New Jersey. Schrodinger is talking to someone on the phone. ...Correct. That's why we came to New Jersey. We're in a laboratory near Raritan River—— You should know about it. ...Yes. The famous 「Edison」's 「Edison Laboratory」 in 「Edison Street」.

Note：

This is the history of the real world.

In late 1875, Thomas Edison (1847 ~ 1931) moved his home to "Monroe Park" in Raritan Town. Here, from the opening of the laboratory in 1876 to the move out of the factory in 1887, Edison developed more than 400 inventions and applied for more than 1,000 patents in 11 years.

In 1925, the state of New Jersey honored Edison by erecting the "Thomas Edison Memorial" at the Site of Monroe Park, where Edison's home and laboratory had collapsed due to disuse.

In 1954, the town of Raritan was renamed "Edison City" to further honor Edison.

Today, Edison is one of the most livable towns in the world.

 Anyway, we're 50km away from Manhattan—— It will have no impact on the citizens. ..... ...I can't stop her. You know how she is. Once an idea pops up in her head she'll do whatever she can to verify it—— If the blueprints do exist, then due to unknown circumstances she hasn't been able to go through with it. ..... Yes, it'll be quite difficult. That is always the hardest part. She has always been a walking haphazard. Who can say she won't invent some kind of device that will nullify all Houkai energy based weapons next. ...Yes. I'm being sarcastic. There is no other workaholic who can work 365 straight like her. But who could possibly stop our dear selfish 「Princess」? Also, Finn is right there too—— Ah, don't talk about him like that. He is a very smart person too, just only about his area of expertise. ..... ...No problem. Let's create a 「surprise」 for them. You planned to come in person from the start, correct? ...Eh? Ivan? Margaret? Benedict? Who are they? ...Wait a moment. Doesn't that mean 「total mobilization」? ...I understand. That is also important. 「To cut the Gordian knot」. There is no need to prolong it any longer. Eh? But of course. There is no need to ask. A certain someone has finally left its home. They might come to help at any moment. Present—— Doctor! Aren't we goning to help?！ ....Hella, hemostatic forceps... ...Here Hey! You two! There's a fight outside! ……So what? ...Huh? Percival, what is the first clause of the doctor's oath? You memorized that last year when you took your license test, right? Hmm..."I will devote everything to the service of mankind." What about the fourth? ..."The health of my patients should be my primary concern." What about number nine? ...I'm going to do everything I can to preserve human life.

Note：

The "Geneva Declaration" is the oath of a doctor appointed by the "World Medical Association". The first edition was proposed in 1948 (at the conference held in Geneva, Switzerland). The full text of his oath (first edition, not the sixth edition used nowadays) is as follows-


『准许我进入医业时：

1.我郑重地保证自己要奉献一切为人类服务；

2.我将要给我的师长以应有的崇敬及感恩；

3.我将要凭我的良心和尊严从事医业；

4.病人的健康应为我的首要的顾念；

5.我将要尊重所寄托给我的秘密；

6.我将要尽力维护医业的荣誉和高尚的传统；

7.我将视我的同业为手足；

8.我将不容许有任何宗教、国籍、种族、政见或地位的上的考量，横亘于我的职责和病人之间；

9.我将要尽可能地维护所有人的生命，自从受胎时起；

10.即使在威胁之下，我也不会运用我的医学知识去违反人道；

- I solemnly, freely, and upon my character swear the foregoing."

 What so you think will happen to the patient if we do not go to debridement and suture now? …… ...Death due to Honkai Corruption cannot be ruled out. So, what else there is to say? Work hard! ...Have trust in your friends next door！ Hmph... so this is the power of the 9th, the Herrscher of 「Earth」 that lived 50.000 years ago? ...The relic that transcends time, commonly referred to as a 「Divine Key」, is quite impressive. ...It's surprising even a weak person like you was able to fend off my attack. Schrodinger-san... No... 「you」... ...How do 「you」 know so much about the 「Star of Eden」? Hm... Is that the question Professor Einstein, the person who has been studying by my side for 7 years, wants to ask the msot? Well, it's fine. That Valkyrie is distracted by my quantum doubles—— So I have plenty of time. In short... You taught me about that 「Divine Key」 yourself. ...? To be precise, the knowledge came from the 「trapped core」 inside of it. ——If you 「sniff」 its 「smell」 anyone can learn it. Got it? I-Is that kind of thing possible...? It surprised me as well. You could say... I have one more sensory organ than you all. It lets me 「sniff」 the information the Houkai has 「written」. Thus knowing about the defensive power of the 9th Herrscher also wouldn't be strange, right? Hey... What else do you know? Oh my. Our 「Hero」 finally dared to ask a question. Let's see... I know a lot of things... I know about New York... I know about the 「Princess」... I have you almost figured out. Ah... I just learned about what's going on with that Valkyrie from earlier. So what do you want to know, 「Herrscher」 of our era? ..... Hey... What's wrong? Wasn't it obvious to anyone that he is a Herrscher? Ah, I see. You all can't sense it. Every single one of his cells are screaming in hunger! 「I want to swallow everything」... 「I want to absorb everything」... ｢I want to remake everything｣! You're wrong... Stop talking nonsense! Hehe... nonsense? Your head may not be able to understand it—— But your body knows well it can no longer endure its hunger! Stop it! Before you do something you won't be able to take back! ...Not being able to take it back? Hahaha, wouldn't that actually be a good thing? ...If you want him to return to the 「right path」 you designed for him, let Welt stand up for himself! Not a chance! I won't let you hurt him! Hmph—— ——Then, I'll start by breaking your shield! Hehe... Listen carefully, gigolo hiding behind a woman. For reasons unknown to you... this woman is honestly trying hard to save your life. ...But it seems she has reached her limit. ...She won't be able to take another blow from my hand. Do you understand what I am saying...? What's the point of 「Excalibur」 if it isn't in King Arthur's hands? ...Well? Are you frustrated? If you want to prove you are different from past Herrscher... If you want to prove you will not succumb to your instincts... No... If you want to prove you are a real man—— Grab your weapon and fight me head on fair and square! ... ...... Hehe don't get hit by her. Y-You are... Me? Who I am doesn't matter. What matters is—— Schrodinger. You can't do anything about her. If you buy enough time Reanna will come back and save you, right? A-Are you saying... Don't... You must face her head on, Welt. You are not an ordinary person—— Believe in your own power. That is the upmost respect you can show Professor Schrodinger. ...Grr! Who the hell are you!? If you are trying to led him astray... ...We won't stay silent. Don't be afraid, we're not your enemy. As long as you don't listen to that blonde devil you won't go down a dark path. Your opponent is Professor Schrodinger. She is ready to fight you until the end. Can you tell why? ... ..... E-Everyone... is calling me. ...What? Eins... Would you lend me... ...The 「Star of Eden」? ..... But... Have you forgotten... there is no limit to the dimension of space. ...! Don't worry. Certainly... my body is longing... to be exposed to this torrent of energy... But... thanks to that... I can feel 「everyone's power」 within me. ...「everyone's power」? Yes. 「Everyone」. It's not only Carl... there are many others, children and adults we've never met. You are... Don't worry. I am... I am myself. Always been, and always will be. So... will you help me, Eins—— Professor Einstein? ... ..... Ahh, I guess every man has this kind of moment in their life. Eh... what? Forget it. It was a little compliment. (This 「World」 is always exceeding my expectations...) (I entrust you 「Welt」's fate.) Meanwhile—— A dozen Houkai beasts suddenly disappeared as if they were phantoms. I realized I was tricked. The one thing I was fearing became reality. From the place I left—— That is, Dr. Morgan's clinic—— A Houkai vortex, which seemed to have been contained by a mysterious power, erupted as if it were a volcano. ...It's exactly as that Professor described. I relied too much on my past experiences. ...It's impossible for me to perform an indiscriminate attack from this distance due to possible collateral damage. Luckily, it seems they still haven't used their triumph card given the Houkai energy shock waves. ...But that doesn't mean I have a single moment to spare. T-This is... There was a large hole in the outer wall of the clinic. Einstein was resting alongside an unconscious Tesla in a pile of hay. The rest of the clinic's staff was near them, looking in awe at the distance. ...Their gaze was focused on the two dangerous energies clashing with each other. What is it, Welt? Don't tell me you've used all your power already? Stop this, Professor Schrodinger! Else human lives will be lost! ...Human lives? Stop joking already. Where is that 「human」 life you speak of! How contradictory! You knew this was going to be a battle to the death the moment you took my challenge! ... Ahaha, what is it? Cat got your tongue? If you don't want me to soak my hands in blood awaken that power of yours! ...No. Just because I can, doesn't mean I want that, but I also don't want to do something I'll regret. But the voices inside of me tell me... You are... not my enemy. ...Hahaha! ...Stop joking! I'm seriously trying to kill you all! ...I don't doubt it. You are seriously trying to kill me... It's true it would be better for everyone if you were to kill me. But even so... I can tell you're not my enemy. You're just my opponent in this battle. Heh... Hehehe... ...What are you trying to say? ...What are you trying to do? ...To be honest, I don't get it myself. Right now there are countless voices whispering within my body. Some voices wish for the destruction of everything. But the majority are encouraging me to bring happiness to this world. The one thing I'm certain is... if I'm killed by you then they will... the last piece of them left in this world... will disappear. So... if you honestly want a duel to the death... I can't let myself be killed without putting up a fight. I still have to make reality the beautiful wishes of those countless voices! Ha... Hahahahaha! You don't have to say anything else. Come! Let's see how long can a 「Herrscher」 last! ... ..... ...Professor Schrodinger. I accept your determination!
