"So according to what you said, we have to find the former residence of the famous writer, and then draw a circle connecting that place with the Père Lachaise Cemetery, right?" Conseil asked.

Severus did not answer.

"There are many famous writers in France, and their addresses are not all marked on the map." Conseil said, "Besides, Paris has been rebuilt for so many years, and it is no longer the same as it was 200 years ago."

"Do you still remember why you want to build the Père Lachaise Cemetery?" Severus asked.

"Of course." Conseil said, "The cemeteries in the city are not enough."

"The catacombs are also." Severus said, "And Lyle Meyer mentioned it."

"So..."

Severus was about to draw a line, but he paused and connected the Père Lachaise Cemetery and the Paris Planetarium.

"Why?" Conseil asked, looking at the straight line.

"The catacombs are a long pit, and the entrance marked on the map now is only part of it. How do you know it is the same as it was 200 years ago?" Severus said.

"Then why did you choose the observatory?" Conseil asked.

"It has never moved, and the people working here have been looking at the sky. Do you think they have discovered the heaven through the telescope?" Severus asked.

"Well, since you said so." Conseil shrugged, "Let's see if there are any writers' residences along this line."

The two buried their heads in the map and searched carefully.

"Here." Conseil pointed to a place and said, "Could it be the Curie Museum?"

"Curie? Madame Curie?" Severus asked.

"She was a scientist, but she was also a writer." Conseil said, "The Curie Museum is where she did the radium experiment."

Severus laughed, "Doing radioactive experiments in densely populated areas?"

"People at that time didn't know this." Conseil said, "Stop making fun of me, okay?"

"It's too recent. Grindelwald arrived in Paris in 1931."

"What about this place?" Conseil pointed to another place, "Place Monge. Monge was a famous mathematician in the Napoleonic era."

Severus looked at the place Conseil pointed to.

"Have you ever been to a Muggle school?" Severus asked Conseil.

"I went for two years." Conseil said listlessly, "Why do you ask that?"

"Then do you know how to draw geometry?"

Conceil looked at him with a puzzled look.

"What kind of books did you read in Muggle school, fairy tales?" Severus said mockingly.

"What are you going to do, hurry up!" Conseil yelled impatiently.

"Are you in a hurry?"

"Don't forget, we have a dinner tonight." Conseil said.

Severus turned his eyes to the map. "How was the conversation with your brother?"

"I didn't see him." Conseil said. "I left a note for him at the front desk of the Ministry of Magic."

Severus was silent for a moment and said, "Monge proposed a Monge circle theorem. The intersection of two mutually perpendicular tangents on an ellipse is on a circle concentric with the ellipse. We must first find two tangents?"

"I don't know what you are talking about?" Conseil said painfully.

"Many streets in Paris are not straight, but there is one street that is definitely straight." Severus said, drawing a straight line on the central axis of the Champs Elysees. "The other straight line is the rose line through the Paris Observatory. It will intersect with the extension of the Champs Elysees somewhere in the Louvre."

After Severus finished speaking, he drew a straight line running north and south through the Paris Observatory. It did intersect with the extension of the Champs Elysees at the Louvre.

"But they are not perpendicular." Conseil shouted as if he had found something wrong. "I went to elementary school, I know what perpendicular is, yours is an obtuse angle."

"From a two-dimensional point of view, it is so." Severus said calmly, "But from a three-dimensional point of view, the projection plane where the rose line is located is perpendicular to the ground."

"I remember this, if two planes are perpendicular to each other, then the line perpendicular to their intersection in one plane is perpendicular to the other plane." Conseil said impatiently, "Great Paracelsus, I can't believe I would say this."

"The point is that the two planes are perpendicular." Severus put down the harsh words, and then drew a circle with Les Invalides as the center and the intersection of Les Invalides and the Louvre as the radius.

"Wait!" Conseil shouted hurriedly.

"What?"

"Don't you want to explain it?" Conseil asked.

"Isn't it obvious?" Severus said impatiently, "The Invalides is his grave."

"Well, if you say that the intersection of the ellipse is the Invalides and Père Lachaise Cemetery, then I think the Champs-Elysées and the Rose Line will not intersect it." Conseil tried to distinguish.

Severus continued to draw the circle.

The arc was a little bit off and crossed Balzac's former residence.

"According to Napoleon's will, he wanted to be buried by the Seine." Severus said coldly, "Père Lachaise Cemetery is a little far from the Seine."

"It was not his choice to be buried in the Invalides." Conseil said at a loss for words.

"Do you know what Balzac, Victor Hugo, and Dumas have in common? They all studied when Napoleon was in power and became famous after he stepped down. What do you think he meant?" Severus asked.

Conseil shook his head.

"What Napoleon did not accomplish with his sword, I will accomplish with my pen." Severus said, "This is what Balzac said. They are relics of his time."

"I can't believe it," Gongseyi said.

"Believe it or not." Severus said indifferently, and continued to "draw" on the map. This time he drew a circle with the Les Invalides as the center and the straight-line distance from the Les Invalides to the Arc de Triomphe as the radius. This time the circle did not pass through Any places of interest or former residences of celebrities.

"Although you seem to be wrong, I still have to ask, why?" Gong Saiyi shouted again.

"Isn't this obvious?" Severus asked. "Where else is more conspicuous than the Arc de Triomphe?"

"Then the Arc de Triomphe is the intersection of two tangent lines? Is it fictitious?" Gong Saiyi asked.

"We can look for the ancient map of Paris, or find the ellipse." Severus said. "We already know the location of the focus of the ellipse."

"You're wasting time." Gongseyi said.

"Really?" Severus said fiercely, drawing another circle.

This circle still takes Père Lachaise Cemetery as the center and the straight-line distance from the cemetery to the Paris Observatory as the radius. As a result, the arc of this circle just cuts through the Tuileries Garden.

"We are looking for the missing building." Severus looked at the map and said, "You also went to the Tuileries Palace that day. Is there anything else you want to say?"

"What about the order of the planets?" Gong Saiyi asked.

"The most special planet in the solar system is the Earth, not only because of humans, but also because the moon revolves around us." Severus said, "I remember you said that Ptolemy's geocentric theory said that the moon revolves around the sun."

"The planetary sequence is the basis of Copernicus' heliocentric theory. If you think that the Invalides represents the earth, then what are these three circles?" Gong Saiyi said, pointing to the three circles on the map.

"There are people buried with him in both the Invalides and the Library. I don't need to tell you who was buried with him in the Invalides. The mummies buried with him in the library are mummies. Do you think there is a mummy of the Pharaoh?" Severus Asked "You can't be considered a member of the 'Five Planets' without a bodyguard."

"So who is the moon? The Eiffel Tower?" Gongsei asked.

"It used to be the Champ de Mars, and I'm not sure if it was the moon or Mars," Severus said.

Gong Saiyi ruffled his hair and walked around anxiously.

"That poem he wrote." Severus said expressionlessly, "He called the moon."

"These are all things after his death." Gong Saiyi said, "He can't even decide where his cemetery is."

"He has executors, and they will ensure that everything goes according to his plan." Severus looked at the map and said, "The library is the starting point."

"What is he hiding there?" Gong Saiyi asked.

"Pomona thinks that heaven should look like a library. I heard that the National Library of France is the cornerstone of French wisdom. He has been looking for a granite foundation for France." Severus paused. "I think His heart is there."

Gong Saiyi was so surprised that he was speechless.

Severus shook his head and whispered, "James Potter."

"I think it's still too far-fetched." Gong Saiyi said.

"How about hiding the third circle?" Severus used wandless magic to hide the circle. "It represents the invisible world."

Gong Saiyi let out a long sigh, "Should you go to Venice or should I?"

"I set up a floo network. Gianluca should go to Padua." Severus said, "I'm going to Père Lachaise Cemetery."

"But I don't know where that place is," Gongsei said.

"You have his cell phone number, call him," Severus said.

"Yes, boss." Gong Saiyi said listlessly, dragging his suitcase away.

After he left, Severus looked back at Pomona lying on the bed.

"I know you want to go back to Hogwarts." He whispered, "But I don't want to go back, because my vision is no longer limited to that school. That place is a prison for me. Those who are here to protect the school And the children who died did not see the wonderful world outside the school. Do you think they are lucky?"

No one answered.

"It's time to go." Severus whispered, walked to the bed, and picked her up gently, like a baby.

It's a good thing she's not a real baby, otherwise she wouldn't be able to apparate or travel via the Floo Network.

It's a pity that I can't post a picture, it would be more intuitive.

Every time in Europe, there are so many dead people that there is no place to bury them, so they dig out the old bones and bury the new bodies in them, for so many years.
