Lu Cheng counted the current number of people and went directly to the road.

The current composition of what can be called the World Saving Team is the departure of the wooden boat of the seven refugees, Grand Prince Scarley.

Two soldiers from the Great Prince's personal guard volunteered to join the squad.

In addition to the normal personnel changes, there is also a strange thing on the car in Lucheng... It's the talking groundhog.

The groundhog didn't realize that he was in the 'car', but thought that he was being put in a cage by Lu Cheng.

Lu Cheng still had some information to ask the groundhog about the reason, and gave up the driving position to the pictorial.

He was in the back seat of the off-road vehicle transporting personnel, asking the groundhog about the level of human civilization in this world.

In the mouth of this groundhog, Scarley is a 'small border country', Scarley's people are 'ignorant rednecks', and the Gmansis Secret Order is the supreme being who controls all truth.

Although Elena listened to the marmot's words, she really wanted to peel her skin and make a roasted marmot.

However, Elena still acknowledges the status of the Gmansis Mystic Order as an organization of magicians who hold the truth.

Lu Cheng is not very interested in what the truth is, and just wants to know how many technology trees have been lit up in the country with the most technology trees in the world, and how many technology trees have been lit up......

First of all, Lucheng asked about the per capita education level.

This is very important, since the majority of the commoners of Scalley were illiterate, which was about the same level of education per capita as in the Middle Ages.

"Literacy? In our Gmansis Secret Pua, the illiterate ones don't even have the qualifications to enter the city, so we won't ...... with that kind of rough countryman."

The groundhog, named Charlotte, heard Lu Cheng's inquiry, and was in the middle of his conversation, when the friendly gaze of Elena next to her prevented her from saying the second half of her sentence.

"How many people will you have in that secret method?" Lu Cheng asked.

"Do you want to join us? If you were younger, maybe I could consider ......."

Charlotte stopped abruptly as she spoke, and she moved to the left on her short legs, and Lu Cheng suddenly pulled out her dagger as she spoke.

"Two... Two thousand four hundred and twenty-seven people. Charlotte glanced at the dagger and said, "This can only be regarded as a spellcaster recognized by our secret spell society, not counting servants, and I don't know how many servants there are." ”

"Servant? Is your country slavery? ”

Lu Cheng captured the key part of the groundhog's words, not all of the Gmansis Secret Magic Society was composed of spellcasters, the casters belonged to the aristocratic class among them, and there was also the existence of the servant class below them.

"Slaves? We don't do such rude and barbaric things, every caster's servant is voluntary, they join the Secret Magic Society after passing the assessment, and if they perform well, they will be given an inscription by the sages to promote to the level of magic apprentice. ”

Charlotte didn't hide this, and many of the things in the Secret Festival were capital that she could brag about, and that she could brag about to these countrymen.

"Well, sage, spellcaster, servant after this."

Lu Cheng probably understands the system of this country.

"You say your country... Or that the Mystic Society has mastered countless truths, so how many truths have you mastered? ”

Lu Cheng began to enter the second stage of the inquiry, which was to figure out which layer this secret magic society technology tree had reached.

First of all, Lu Cheng has to make sure how much knowledge he has mastered, and this 'chief apprentice' from the Secret Order of Gemansis can give Lu Cheng a reference.

"Are you questioning my knowledge?" Charlotte heard Lu Cheng's questioning and regained her inflated courage.

This time Lu Cheng did not hit her sharpness, this groundhog was only seventeen years old when he was a human, this age should still be in the third year of high school on Earth, and if he had studied a year earlier, he would have already started college.

For the sake of conservatism, Lu Cheng still starts with the knowledge of primary school, first of all, mathematics as the mother of Vanke.

Numbers have appeared in this world, and what makes Lu Cheng feel very strange is... The mathematics of this world is also the decimal system, and the number units such as ten, hundred, thousand, and ten thousand already exist.

"What is the largest number you can count from the beginning?"

Lu Cheng asked a question that seemed to the earthlings to be a kindergarten child.

"Such a simple question to question my knowledge?"

Charlotte also showed disdain when confronted with Lu Cheng's first question.

Lu Cheng didn't answer, just lightly brushed the surface of the dagger with his fingertips.

"One, two... Three..."Charlotte honestly began to count, and when it came to the hundredth number, she finally ran out of patience.

"There's a thousand, ten thousand, and the numbers are infinite, don't you even know that?" Charlotte complained about the strange questions Lucheng had given her.

"Elena, Noi, what about you?"

Lu Cheng once again ignored the groundhog and set his eyes on Charlotte and Noi who were watching, and Noi had been silently listening to the communication between Lu Cheng and Charlotte just now.

After Lu Cheng came up with the first question, Noi began to count with his fingers.

"My mother also taught me a lot of things, including computing... I can count the numbers all the time," says Elena.

Hearing Elena's answer, Noi suddenly pursed her mouth slightly, and the hands that were originally folding and counting were hugged together, a little overwhelmed.

"Don't worry, you'll learn later."

Lu Cheng saw that Noi's progress in math was far inferior to that of Elena as a royal and the chief magic apprentice groundhog, no... It should be called Charlotte.

As a clergyman in a border town, Noi can already know so many words, and she is only fourteen years old.

"That's all you have to ask?" Charlotte asked.

"Second question, you have twelve ducks, and the neighbor next door gave you thirty-three ducks, how many ducks do you have now?"

Lucheng raised the problem from the kindergarten level to the first grade of primary school.

"Forty-five! Even the ten-year-old servants in our secret puja know this. Charlotte said.

Lu Cheng turned his gaze to Elena.

"Why did the leader give me ducks? Not... The number I counted was also forty-five. "Elena's way of thinking is a little different, but she still knows such simple arithmetic addition and subtraction.

"Is that all you have to do with calculating ducks?" Charlotte said to Lucheng a little defiantly after hearing Elena's calculations.

"Well, suppose you have two newborn rabbits on your farm, and in the second month the two rabbits mature quickly and a female rabbit becomes pregnant, and in the third month she gives birth to two more rabbits, and every month after that, new rabbits will continue to be born like this, and if this situation continues, and the rabbits never die, how many rabbits will you have on your farm after sixty-four months?"

Lucheng asked a question about one of the most well-known Fibonacci numbers on Earth, also known as the rabbit series or the golden ratio series.

Fibonacci is also a well-known mathematician of the twelfth century on Earth, this number series has applications in various fields, and is one of the most important mathematical achievements in the development of human civilization.

According to the progress of Scarley's civilization, this world should also be around the twelfth century... It should be a bit far from the Renaissance.

However, Lu Cheng can't figure out the development of this world civilization from the perspective of the earth, but Lu Cheng is still curious about how the world's mathematics is developing.

Judging from Charlotte's expression, it seems that it is not optimistic.

"What? Do you say it again? Charlotte, who was in a groundhog state, looked sluggish, as if she was going to come out 'ah...' in the next second.

Elena was also in a state of silence.

Lu Cheng had to patiently explain the problem again, but Charlotte was still in a state of confusion, as if she had fallen into the magic of silence.
