Harry Potter’s Morning Light

  Chapter 1642 frog&fog (thirty)

   "So according to your statement, we need to find the former residence of the famous writer, and then connect that place to the cemetery of Father Lachaise and draw a circle, right?" Gonsey asked.

   Severus did not answer.

   “There are many famous French writers, and their addresses are not all marked on the map.” Gonsaiy said, “not to mention that Paris has been rebuilt for so many years, and it has long been different from 200 years ago.”

   "Do you remember why you want to have Father Seurachaise Cemetery?" Severus asked.

   "Of course." Gonsey said, "The cemetery in the city is not enough."

   "So does the catacombs." Severus said, "and Lyle Meyer mentioned it."

"and so……"

  Severus was about to draw a line, but he paused when he saw him, connecting Father Lachaise’s Cemetery to the Planetarium in Paris.

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

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

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

  "It hasn't been moved, and the people working here have been looking at the sky. Guess if they found heaven through a telescope?" Severus asked.

   "Well, since you said that." Gonsey shrugged. "Let's see if there are any writers' residences on this line."

  The two of them buried their heads on the map and looked carefully.

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

   "Curie? Madame Curie?" Severus asked.

   "She is a scientist, but she is also a literati." Gong Saiyi said, "The Curie Museum is where she did the radium experiment."

  Severus smiled, "Doing a radioactive experiment in a densely populated place?"

   "People at that time didn't know this." Gong Saiyi said, "Don't be sarcastic?"

  "It’s too close to modern times. Grindelwald came to Paris in 1931."

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

  Severus looked at the place where Gonsai was pointing.

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

   "I have been there for two years." Gong Saiyi said listlessly, "Why do you ask this?"

   "Then do you know the descriptive geometry?"

  Gon Saiyi looked at him with a puzzled look.

  "What books did you read at Muggle School, fairy tales?" Severus sarcastically.

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

   "Are you in a hurry?"

   "Don't forget, we have to go to a banquet tonight," said Gong Sai.

  Severus turned his gaze to the map, "How's talking with your brother?"

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

  Severus was silent, and said after a moment, “Monge proposed a theorem of the yen. The intersection of two perpendicular tangents on an ellipse is compared to a circle concentric with the ellipse. Should we find two tangents first?”

   "I don't know what you are talking about?" Gonsai said in pain.

"Many streets in Paris are not straight, but one street is definitely straight." Severus said, drew a straight line on the central axis of the Champs Elysées. "The other straight line passes through the Paris Observatory. The Rose Line, which will meet the extension of the Champs Elysées somewhere in the Louvre."

  Severus finished speaking and drew a straight line running north-south through the Paris Observatory. It did intersect the extension of the Champs-Elysées at the Louvre.

   "But they are not vertical." Gong Saiyi yelled as if he had found something wrong, "I went to elementary school, I know what vertical is, you are all obtuse angles."

  "From a two-dimensional perspective," Severus said calmly. "But from a three-dimensional perspective, the projection plane on which the rose line is located is perpendicular to the ground."

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

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

   "Wait!" Gong Saiyi hurriedly called.

"what?"

  "Don't you explain?" Gonsai asked.

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

   "Well, if you say that the intersection of the ellipse is Les Invalides and Father Lachaise Cemetery, then I don't think the Champs Elysées and the Rose Line will intersect it." Gonsey tried to distinguish.

  Severus continued to draw circles.

  The arc was a little bit short, and it passed the former residence of Balzac.

   "According to Napoleon's last words, he is going to be buried by the Seine." Severus said coldly, "Father Lachaise Cemetery is still a little far away from the Seine."

  "He didn't choose to be buried in Les Invalides." Gon Saiyi said in a humble words.

"Do you know what Balzac, Victor Hugo, and Alexandre 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 to express? ?" Severus asked.

  Gonsai shook his head.

   "What Napoleon didn't do with a sword, I will do it with a pen." Severus said, "This is what Balzac said. They are relics of his time."

   "I can't believe it," Gonsai said.

"Believe it or not." Severus said coldly, and continued to "paint" on the map. This time he took the Invalides as the center and the straight line distance from the Invalides to the Arc de Triomphe as the radius. This time the circle did not pass. Any historical sites or former residences of celebrities.

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

   "Is this unclear?" Severus asked, "What else is more prominent than the Arc de Triomphe?"

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

   "We can find the ancient map of Paris, or find the ellipse." Severus said, "We already know the location of the ellipse's focal point."

   "You are wasting time." Gong Saiyi said.

   "Really?" Severus said fiercely, and drew another circle.

  The circle is still centered on the cemetery of Father Lachaise and the radius is the straight-line distance from the cemetery to the Paris Observatory. As a result, the arc of this circle just crosses the Tuileries Garden.

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

   "So what about the order of the planets?" Gonsai 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 center of the earth said that the moon revolves around the sun."

  "The planetary sequence is the basis of Copernicus' heliocentric theory. If you think of the earth represented by the Invalides, what are these three circles?" Gonsai said, pointing to the three circles on the map.

"The Invalides and the library both have funerals. Who is the one who buried him in the Invalides? I don't need me to tell you. The mummies in the library are mummies. Do you think there will be pharaoh's mummies?" Severus Asked, "You can't be considered a member of the'five planets' without a funeral."

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

   "It used to be the Plaza of Mars. I can't be sure if it is the moon or Mars." Severus said.

  Gon Saiyi messed up his hair and walked around anxiously.

   "That poem he wrote." Severus said blankly, "The moon he called."

   "These are after his death." Gonsai said, "He can't even decide where his cemetery is."

   "He has an executor, 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 did he hide there?" Gonsai asked.

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

  Gon Saiyi was so surprised that he could not speak.

  Severus shook his head and whispered "James Potter."

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

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

  Gonsey sighed, "Are you going to Venice or me?"

   "I built a flyway network, Gianluca should go to Padua." Severus said, "I'm going to the Cemetery of Father Lachaise."

   "But I don't know where that place is." Gong Saiyi 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 who was 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 want 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, and walked to the bed and picked her up softly, like a baby.

  Fortunately, she is not a real baby, otherwise she cannot use Apparition and Floo Net to travel.

  　How idle I am

  　　 Unfortunately, I can’t post the picture, it’s more intuitive
