This morning, the photographs taken by Bella and the others from Mr. Daguerre were delivered.

Elena couldn't wait to unwrap the package. A beautiful daguerreotype is presented in front of you.

In the golden frame, the images of the three people are clearly printed on the silver plate.

The photos have been professionally sealed, and as long as nothing else, they can theoretically be kept for a long time.

"But...... Why is it the other way around?" Elena pouted.

At that time, she was obviously sitting on the right, but on the left side of the photo, and the direction of the hat was also reversed.

In short, the whole is a mirror effect.

"That's fine." Elena didn't particularly mind, "No matter how you look at it, I look beautiful!"

She was immersed in a narcissistic appreciation.

Bella only glanced at it and didn't pay much attention to it.

Anna was very curious about the macarons she was holding at that time. Although the macarons themselves are pink, they turn gray when printed on the photo.

"If only the colors could be recorded." Anna muttered, then took a bite of the handmade cookie next to her as a sign of comfort.

Because this kind of daguerreotype photography cannot be reproduced, this only one is precious. Elena spontaneously took on the responsibility of preservation.

Attached is a message from Mr. Daguerre, which includes a few words of blessing and some notes on saving the photo.

"Cherish yourself." Finally, he concluded.

It seems that Mr. Daguerre treats each photograph with great care.

"Why didn't you see Margaret today?" Elena asked curiously.

At this time, the rabbi would have fallen asleep with Anna on the couch long ago.

"But then again, it's really strange that Anna didn't sleep today!" Monsieur Diderot quipped.

"You don't know yet, Rabbi is sick." Madame Roland said suddenly.

"Huh? When did it happen?" Elena was a little surprised.

The day before yesterday, I said it well.

"It looks like yesterday afternoon." Madame Roland said, "Didn't you go to a food festival? Margaret had something to do, so she didn't get over in time. So, it wasn't until late in the evening that I had the opportunity to take the rabbi for a walk. Later, I didn't know what I ate, and when I went back, I vomited and vomited."

"How's it going?" Elena asked worriedly.

"It should still be with Dr. Raenek." Mrs. Roland replied.

This conversation made Bella and Anna a little worried.

So, the three of them decided to leave for the main palace hospital to visit the rabbi's condition.

Anna also asked Vanessa to help pack a few cookies for the rabbi to eat.

The Hospital of the Main Palace is located on the island of Sitti, next to the Cathedral of Notre-Dame. You need to cross the Seine via a stone bridge to get there.

The three of them are quite familiar with the road.

However, as soon as he crossed the Seine, he saw Officer Christophe and his men from the Île de la Cité checking passers-by.

"What's wrong?" Elena stepped forward and asked.

"It was just a few of you." Officer Christopher saluted and said, "It's okay, you can go over."

"What the hell is going on?" Elena continued.

"Someone has just been spotted smuggling arms, it seems to have entered the island of Sitti, and we are investigating it closely." Officer Christopher replied.

"Smuggling?"

"Yes, because the political situation in Europe is very tense right now, and France has just concluded an alliance with Austria, and if it is discovered that arms smuggling is detected, it is likely to affect the current political situation. So, it's very important."

And Officer Christopher was also temporarily transferred here from the Paris General Directorate.

"It's been so hard." Elena said, "The officer just got busy with the Perfect Food Festival yesterday, right?"

"Well, it can't be helped, it's the duty."

Although he was a little helpless, he didn't complain very much.

With the approval of Officer Christopher, Bella and the others entered the island of Citi without any problems.

The main palace hospital is located in the heart of the island of Citi.

After passing through the square in front of Notre-Dame Cathedral, you will come to the main entrance of the hospital.

René Théofel Laenéc is one of the more well-known physicians here and has his own private consultation room.

Through the consultation at the front desk, Elena and the three successfully found Miss Margaret's location.

"I didn't expect you to come." Miss Margaret stood up to meet them.

"How's the rabbi?" Elena asked.

"Mr. Raenek has already washed its stomach, so it should be fine." Margaret said.

And the rabbi was already asleep in the chair next to him.

"What the hell did you eat?"

"It looks like chocolate."

"Chocolate?" Elena was puzzled, "Can't cats eat chocolate?"

"Hmm...... That's what Mr. Raenek said." Margaret replied, "And he made a point of telling me not only chocolate, but also coffee and the like. In short, everything made with cocoa should not be eaten by it, otherwise it will be poisoned."

"Poor rabbi!" Elena looked sympathetically at the sleeping Persian cat.

Just then, Dr. Raenek walked in.

He leaned down and took a closer look at the rabbi in his chair.

"How's it going, doctor?" Miss Margaret asked nervously.

"There should be no problem." Mr. Laenek replied, "When you go back, you will feed them normally, and don't feed them anything too irritating for these two days."

"Thank you so much!" Miss Margaret said gratefully.

"Nothing, it's my job." Raenech said.

"No, thank you anyway." Margaret thanked her again, "I thought I couldn't find anyone who could treat the rabbi."

"Well...... I'm ashamed." Raenek said apologetically, "Actually, I'm not a veterinarian either."

On the sign at the door of the clinic, it says Respiratory Department.

"But you did cure the rabbi."

"Well, I was actually taught this by a friend of mine from the University of Paris." "He was a material researcher, but he was particularly interested in the reactions in living organisms. And the fact that cats are allergic to chocolate is what he told me."

Listening to Mr. Laenek's description, Bella always felt that this person was somewhat familiar.

"Doctor, the friend you are talking about from the University of Paris must be surnamed Pasteur, right?" Elena asked.

"Huh? Do you know Louis?" Mr. Laenek said in surprise.

Just then, a young man appeared at the door of the consultation room.

"I said René, you're pretty good at that." Monsieur Pasteur walked in with a cylindrical bamboo pipe in his hand, "Huh? It's such a coincidence, how many of you are too?"

"Mr. Pasteur, you are everywhere!" Elena said.

"You're kidding, I'm only here once in a while to chat with Dr. René." Mr. Pasteur said.

"I didn't expect that Louis, you still know so many beautiful young ladies, you really can't see it!" Mr. Raenek said jokingly.

"You're exalting me too much. Almost all the ladies I've known in my life are here—even though they're all beautiful."

These two old friends who are not far apart in age have a similar smell at first glance.

"By the way, Monsieur Pasteur, what is this in your hand?" Elena asked, pointing to the bamboo pipe in his hand.

"Well...... "Monsieur Pasteur handed it to Elena, "but it's Dr. René's latest invention!"

"Huh?" Elena took the strange bamboo pipe with great interest and put it in front of her eyes to look at it.

"You don't see with your eyes, you hear with your ears!"

As he spoke, Mr. Pasteur came over and pressed one end of the bamboo pipe against the left of his chest, and asked Elena to listen from the other end.

"Listen carefully." Pasteur said mysteriously, "What did you find?"

Elena leaned her ear close to the other end of the tube and listened carefully.

Then, I heard the sound of "plop, plop, plop......".

"Yes—heartbeat!" Elena said in surprise.

"That's right," Mr. Pasteur nodded in satisfaction, "isn't it clear?"

"It's amazing!"

Elena was very excited, and immediately listened to the hearts of several people at the scene.

"Is this Mr. Raenek's invention?" Bella asked, looking at the auscultation tool made of bamboo.

"yes, I think René is a genius, right?" Monsieur Pasteur proudly praised his good friend.

"But if you want to listen to your heartbeat, wouldn't it be nice to put your ear to your chest?" Miss Margaret asked.

Why use such a troublesome tool, isn't it superfluous?

"Well, it's an interesting fact about René." "Just a few years ago, a beautiful young lady came to his office. The lady was suffering from heart problems, she seemed to have chest tightness all the time, she was very uncomfortable, and she often had an unbalanced heart rate. So, according to the usual fluency, René was sure to have a cardiac auscultation. But, you know, René was still a young and shy young man! He would be absolutely embarrassed to ask him to put his ear close to the lady's plump breasts!"

"You say this as if I'm old now." Mr. Raenek said complainingly.

"No, no, you're still strong!" Monsieur Pasteur chimed in.

"But Louis said it pretty differently." Mr. Raenek explained, "I was a little nervous. Because, she is so beautiful and has a good figure, I am really a little shy. So, on the spur of the moment, I rolled a wad of paper beside her into a cylinder and placed it on her chest for auscultation."

As he spoke, Mr. Laenek picked up the paper on the table, rolled it into a tube, and made a demonstration.

"It's a blessing in misfortune." "Later, I thought this method could be developed, so I experimented with various materials. So, you have this bamboo tube stethoscope that you see, and it can be used for a long time. That way, I don't have to worry about that kind of embarrassing scene anymore."
