Let's talk about the past. There was a certain Greek hero... Well, it doesn't really matter where he came from. Anyway, he was a great man and his ship was turned into a monument of sorts, and was worshiped by people. But time is cruel and the ship's wood slowly decayed. The locals came up with a plan to preserve their precious ship—— Every year each part of the ship would be inspected, and if any part was rotten it would be rebuilt. A few hundred years later a philosopher came to see the ship, and by then each part had been replaced at least once. The philosopher was very saddened to hear that and asked the locals 「Is this still the original ship?」. And the locals told him in a thoughtless manner—— 「Philosopher, if you believe this ship is different, then when did it stop being the original?」 「As you must know, even during the great hero's voyage the ship had its parts replaced.」 ..... I woke up from a dream. For some reason I'm sitting on a bench. Ah... ...I remember now. That red haired cowgirl brought me here. Because I saved her life. ...I fell asleep shortly after arriving here. ...How embarrassing. Even though the energy consumption from 「Zero Level」 should be insignificant. I guess... ...I am lowering my guard around these people? Thankfully, it hasn't been that long since I passed out. After taking a short breath, I noticed the smell of carbolic acid in the air.

Note：

Carbolic acid, or phenol (chemical formula: PhOH), is the simplest phenolic organic substance; its dilute solution is the earliest disinfectant used in modern medicine. Phenol is an unsafe disinfectant. Its concentrated solution has a strong ability to penetrate and corrode the skin, and is highly toxic; in modern times, its main use is in chemical synthesis, such as the manufacture of aspirin and phenolic resin.

 The bright light from the morning Sun entered diagonally from a small window at the end of the hallway. The strong contrast of light and darkness gave this questionable clinic a strange atmosphere. Hi. Hello Holding out a hand to the side expressionlessly... ...Seems like she meant to shake hands. Mikhail Morgan. The person in charge of this clinic. Reanna Brigantia, Valkyrie of Schicksal. Your companion is replenishing their energy next door...Do you need some? High calorie foods. Oh, no need. I...I had a full breakfast, haha. I see, then I'll enjoy it myself I guess. With that, she peeled a piece of chocolate and threw it in her mouth. Right. Thank you for helping Elaine in time. That idiot, if we hadn't been here before, would've been dead several times. However, what I am curious about is-what exactly is your "field medical equipment"? Ahaha...that.. Well...This caviar tastes really good. The texture of the bread is just right. Right? They always have a way to get some really good stuff. Like this Caspian Urga caviar, the Istraya truffle, the Iberian Oak ham...

Note：

European sturgeon (scientific name: Huso huso) is a fish belonging to the genus Sturgeon family Sturgeon. Its common name is "European sturgeon". It is also called "Black Sea Stray" and "Caspian Sea Stray" because of its origin. The European sturgeon is one of the largest freshwater fish species in the world, and is also the largest and most precious species of sturgeon, with a body length of more than 8 meters and a weight of more than 1 ton. The caviar of the European catfish (especially produced in Astrakhan, the "mouth of the Volga River") has plump eggs, a smooth taste, and a long-lasting aftertaste. It is the most delicious and valuable variety of all caviar.

 Huh? Is Dr. Morgan that rich? Hmm...Should I say that I have money...or that I know more people... Uh-huh... No matter how good the delicacies of the mountains and the sea are, it can't fill your stomach, right? Come on, wait a minute — banana chocolate cake. Ugh, it smells so good! Mhm, its even better than the ones my mom used to bake! Of course, you treat me as a bunny girl for nothing. You're welcome! Cough...Eat slowly, so you don't choke. Do you need me to pat away your hiccups? ...You are one to talk Mophead. Uh huh...She's right though. Even if you are in a hurry, you should eat slowly. ... Speaking of which, Miss Hellawes, what exactly are you doing for Dr. Morgan? Right now......Part-time nurse, of course. Don't look at me like that -- I'm actually licensed, alright. Usually there is no need for so many people in a clinic... However, there's always some room for exceptions, no? Since the sudden power failure in the middle of last night, Dr. Morgan has called all of us here— As you can see, the girl next to me hasn't even changed their clothes for the night shift. Wait...So you were always an established..."Organization"? Uh, Well... it's a bit too much of an exaggeration to just say "organization"... But yes, it's true we are a "business team." of sorts Parcival and I are in charge of inquiring about the news, Elaine is in charge of running business and money debt collection, as for Dr. Morgan-of course she is the brains of the whole thing. Ah... could it be that... Huh? We didn't do anything illegal, did we? Heh, you're thinking too much again, aren't you? There are few who have courage to do business using their heads you know?...Anyways, the cake is finished! Let's break open the wine bottle! That one! "“塞纳之花”" Don't drink anything! Come and help! The back door of the clinic was suddenly flung open by a burly young man in an ill-fitting white coat. Percival, you -- Oh, my God, someone's hurt? What are you still waiting for? Take him to the doctor quickly! This person needs immediate Help! The burly young man took off his shoulders, a man in a suit covered in blood and dying. There were strips of wounds on the man's back -- deep and shallow, judging by the extent of the tear. These are......scratches by a beast? I don't know！ I'll leave this man to you, there's another one lying in the doorway! ...M! What is the situation? They're just flesh wounds. It's no big deal. ...Oh? There's no damage to the aorta or the main nerve, just a normal muscle tear. It should be fine after one or two months of resting. Only…… Only what? ....Forget it. I'll let Miss Brigantia, who's good at explaining things, explain it to you. I still have to stitch them up. Uh-huh....That....I really need to keep this one a secret. I'm sorry. Tsk, don't apologize for looking after him. Reanna what the hell is going on? Their wounds show signs of Honkai Corruption. They doesn't look too serious, but there's no doubt about it, this is the work of Honkai Beasts. In addition, the manner of the laceration is eerily smooth, which shows that the enemy had an exceptionally fast method of attack, Which would be difficult for ordinary people to prevent. So... You stay here and help the doctor. I'll take it out, no problem. ……No problem? Can't this be a trap? Doctor, I've killed many Honkai beasts...But none of them can compare with the intelligence of man, nay, even mammals. The clinic had not been directly attacked -- the way the situation is unfolding, it should be safe here for quite a while. Besides, if my guess is correct... ...You also have a "ace" in your hand, right? …… After a mysterious wink, Reanna picked up the Abyss Flower and left the clinic. "Ace"? What did she mean by that? Uh…… That's... Here. Out of nowhere, the girl pulled out a handful of silver-gray bullets and handed them to the red-head. This is... "Silver Bullets."

Note：

A silver bullet is a musket bullet made of silver. In European medieval folklore, silver products, such as silver knives, silver forks, etc., are the only weapons that can fight against werewolves, witches and other monsters. Therefore, in the extended meaning, "silver bullet" also means a powerful, once and for all, "all-purpose trump card" suitable for various occasions.

 Huh? I'm kidding. There's no such thing. This "Astra Ammunition" is an ammunition made of the alloy invented by this Dr. Tesla. It's armor sunder effect on Honkai beasts is quite good.

Note：

"Astra" (Sanskrit: अस्त्र) is a general term for a class of supernatural weapons bestowed by gods in Indian mythology.

For example, "Pashupatastra" (Pashupatastra), that is, Shiva (Shiva, the god of destruction in Indian mythology, and the god of beasts) bestowed on Ajuna's "Astra", whose power is said to be strong enough to destroy the universe.

 Ah...For...Ha ha...Let's just say it worked, right? Anyway, even though it's an armor-breaker, it's a.45... Do you have anything fit to load?

Note：

.45 Auto (.45 automatic pistol bullet), also known as .45 ACP (Automatic Colt Pistol, Colt automatic pistol), is a type of ammunition used by many pistols and submachine guns in the United States. Easily cause fatal damage to unprotected targets...

...However, in our story, Tesla took a different approach. She took advantage of the self-sharpening effect of Tyre alloy—that is, the special properties of uranium that can achieve liquefaction and puncture under high-speed rotating friction. This is a .45 supersonic armor-piercing bullet that can also be used with a light firearm.

p.s. ".45" means that the diameter of its bullet is about 0.45 inches.

 He-hey…… Come on! A typewriter for everyone! Oh, oh, Thompson! With this guy in hand, you don't need to be afraid of anything.

Note：

"Chicago Typewriter" is the common name of the Thompson submachine gun. It is named because it fires like a typewriter and is the iconic weapon of the Chicago gang in the 1930s. The outstanding close-range lethality of the Thompson series made it one of the most popular submachine guns in the world at that time-second only to the "Bobosha" series of the Soviet Union.

 ...That's a submachine gun, right? Do we have that many bullets? Damn right we do! There's an entire case in that sports cars we've been riding on. A-An entire case!? What? Isn't it very much like her? Mass produce something and keep it stashed in many different places. She...? ..... Edison! ..... A-Ah, you meant Nancy. W-Why are you angry? ..... You can't say her name anymore today, got it? ...Just hearing it pisses me off! It's more annoying than 100.000 mosquitoes, fleas and flies! S-Sorry. ..... Tch. Are you stupid? Eh...? You apologizing won't do anything. ..... If something were to happen to us, would you apologizing make everything okay again? Will it? Well? Huh!? Knock. Knock Knock. Knock Knock Knock. ...Isn't someone knocking? ...I'll go check it out. Woah! W-What are you doing...? Out of my way, weaklings. I have business with that harem lead over there. Yes, you. ...Come out, 「Welt」. ...And die.
