This witch calls me daddy

Chapter 515 Math Puzzle
Lu Ye looked at Sophia beside him and didn't understand what she meant by suddenly solving an arithmetic problem for elementary school students.

But seeing the excited anticipation on her face, Lu Ye guessed that this might be related to the treasure they were looking for.

The question is not that difficult, it just requires enumeration and calculation to rule out impossible situations...

Since there was nothing to do while driving, Lu Ye started doing mental arithmetic.

The multiplication of three numbers is equal to the sum of these three numbers plus 3...

So this becomes an arithmetic problem within 9.

In addition, there are no twins, which means there are no identical numbers... Soon, Lu Ye gave the answer:

"1, 2, 6?"

Sophia chuckled: "Correct!"

Without Lu Ye asking any more questions, she began to explain the origin of this question:
"This question is an interesting mathematical puzzle published by the imperial mathematician Leibniz in the imperial popular science magazine "Digital Science". It is for children to expand their thinking and is widely circulated in the empire."

Lu Ye: "So, is it related to the treasure?"

"Yes. During my investigation, I found an interesting thing. When he was young, this mathematician once served as a tutor for the imperial noble Byron family. The most well-known Byron family is that Sebastian, a former Imperial Field Marshal with the title of 'Imperial Sword'."

Lu Ye still remembers that this Sebastian is one of the "Three Imperial Eagles". Sophia and Vlad both suspected that the empire's treasure was the aftermath arranged by them.

Lu Ye: "So... this mathematician is the teacher of Imperial Mitaka?"

Sophia shook her head: "No."

"Then what's his relationship with the generals?"

Sophia smiled and continued to shake her head: "No intersection."

Lu Ye frowned: "What's the connection between the two?"

Sophia shook her head proudly: "The first time I noticed this clue was not because of the title itself, but because it happened to be published on the day the empire announced its surrender. There was some coincidence in the timing."

"In fact, at the end of the Imperial Era, Leibniz had left his homeland and traveled to the First Commonwealth to teach at a well-known university. It is obviously impossible for him to have anything to do with the declining Imperial Army."

"But it was precisely at that sensitive time that this little story was published in the internal academic journal of the empire that Leibniz often contributed to in his later years. It vaguely revealed a sense of recalling the past and missing the motherland..."

"Considering the attitudes of various countries towards the evils of empire at that time, I guess that Leibniz expressed his homesickness in a subtle way."

Lu Ye frowned slightly. Objectively speaking, he felt it was a bit far-fetched.

But reasoning usually involves bold assumptions and careful verification. I wonder if Sophia found any specific evidence during the verification process.

Sure enough, the second princess continued to explain: "I followed Leibczny's news to look for clues, and sure enough, I found a clue that was enough to prove that the two are related, which is the three daughters in the story."

"Sebastian, Guderian and Vincent have a total of six children, but each of them happens to have a daughter. Moreover, in the year when Sebastian was bombed on the north coast, the three generals' daughters They are 6 years old, 1 year old...and 2 years old."

Lu Ye's eyelids twitched.

If the information is correct, this is a bit too much of a coincidence.

This looks more like the mathematician releasing a public message, implying that he has a relationship with the three generals!

"But how could a mathematician in the Federation know the whereabouts of the Empire's treasure? If he has any connection with the three generals or the Emperor's bloodline... he has not been discovered?"

Sophia shook her head: "Impossible. Leibniz left the empire at the beginning of the Imperial War and has never had contact with the empire since then. Moreover, the liquidation after the war was very intense. If he secretly assisted the empire, he would definitely Being found out..." "So I am more willing to believe that this little story may be a clue left by others under the guise of his hand."

Lu Ye still found it a bit strange: "Leaving clues in newspapers and periodicals...is this challenging the wisdom of the world?"

Sophia smiled: "This is also a proverb of the empire: keep secrets in the open, and they will be harder to find."

Lu Ye nodded: "Well, this can only prove that mathematicians and generals are connected, but it cannot point out the location of the treasure. What will you find later?"

As expected, Sophia had a backup plan. She took out her investigation notes and said with a smile: "With this discovery, I checked all the publications published by Leibniz since then. Found a puzzle..."

Seeing her smiling face, Lu Ye knew that she was going to ask another question:

"Okay... come on, what's the question?"

The princess pursed her lips and smiled: "This puzzle is called 'Journey to the Desert'."

After hearing the name, Lu Ye looked at the Death Sandbank that he had arrived in front of him, and he couldn't help but believe it a little more.

Then I heard Sophia say:

"Three people travel into the desert together and can only walk 9 kilometers a day. If each person can only carry 24 days of food and water, what is the furthest distance they can travel? The question requires that all three people survive... …”

After Lu Ye listened carefully, he sighed in his heart:
Fortunately, this mathematician only solves elementary school-level math problems, otherwise no one would be able to find this treasure...

Oh, just do the math...

...If one of you is asked to return halfway, leave water and food for the others, and let the other two set off with a full load of supplies.

Let the second person return halfway, leaving the last person to set off with full supplies...

The first person can only walk for 6 days, and the second person can only walk for another 6 days, so the third person has to go forward on the basis of 12 days... and walk for a few more days to ensure that he has supplies. Come back alive?

The answer is to go for another 6 days.

"So the final answer is 18 days, multiplied by the speed... the answer is 162 kilometers."

Sophia nodded: "Yes, 162, are you familiar?"

Lu Ye was startled!
Yes, 162, this is actually linked to the first question.

Sophia took out the map and explained the rest of the reasoning process: "I chose the starting point at the Eye of the Sandbank where Vincent last defended. This is also the farthest border facing the Death Sandbank. From here, the radius is 162 kilometers. ...The answer may be here.”

On the map, there is a small mark that is almost impossible to detect. It is the only oasis in the desert called "Emeron".

Sophia pointed here and said softly in an almost pious tone:

"In the local dialect of Central and South China, Aimaerun means...hope."

Lu Ye smiled slightly.

He still remembered that Sophia once mentioned that there was a note that the "Eagle of the Empire" was called "the person who buried the hope of the empire."

It seems that Sophia's wild imagination...may have guessed it right.

Continue to exert force on your feet, increase the speed of the off-road vehicle to the extreme, and run towards the sandbank.
