Success!

Feiyuan quickly went to his workstation, displayed all the data he had organized, and demonstrated it for Su Hao.

"Mr. Jia Wei, look. Most of this data is accurate, while a small portion has errors, but that does not affect our ability to summarize the pattern. I compared the data based on factors such as the timing and intensity of disasters, then grouped it. As I continued subdividing it, the data unexpectedly ended up pairing off two by two.

"I then used the same method to analyze the data from all regions, and every result came out in pairs. Only the few erroneous pieces of data could not be matched.

"At first, I did not understand why. Then I happened to see the Planet Model you created, Mr. Jia Wei, and suddenly understood. Mr. Jia Wei, what shape is the planet beneath our feet?"

Su Hao was in an excellent mood and readily played along with Feiyuan's explanation. He glanced at the Planet Model beside them and chuckled. "An ellipsoid!"

Feiyuan danced with excitement. "That's right, an ellipsoid—and not an ordinary one. I calculated it carefully before. The planet beneath our feet is an almost perfectly shaped ellipsoid.

"Then, as I looked at it, a thought suddenly popped into my brain: what if we treated these disaster locations that paired off two by two as the foci of ellipses...

"So I dug through all kinds of data on terrain, climate, vegetation, and more. Through calculations, I found the traces of ellipses using five pairs of disaster data as foci.

"I only found five groups, but that is enough for us to boldly draw a conclusion about these paired points! They are either the foci of ellipses or the centers of circles...

"Next, we only need to follow this line of
