"Ahem."

Chen Ke looked a little embarrassed, he coughed lightly before saying, "Brother Li, this is true." ”

"If you have any questions, just ask me yourself, why do you want to convey them?"

Fusu covered his mouth and smiled: "Then who made the teacher's laziness known to everyone inside and outside the court?" ”

Chen Ke shook his head, looked at the person in front of him, and scolded with a smile: "You rebel." ”

"Now you dare to ridicule your son as a teacher, what about your respect for teachers in the past?"

Fusu looked at the sky and the earth, pretending not to know anything.

Chen Ke rolled his eyes, looked at Fusu, who no longer had the gentlemanly demeanor of the past, and said, "Okay, okay, what question did Li Si ask me?" ”

"Just say it."

Fusu then spoke: "Teacher, didn't you propose to improve the household registration system and let everyone compile an ID number?" ”

Chen Ke nodded slightly: "Well, what's wrong?" ”

Fusu recounted what Li Si said, and repeated: "Teacher. ”

"Prime Minister Li Chengcheng said that the hukou system matches the redivided counties and counties, and each district and county gives a number, and they have done it."

"But at the same time, a problem has emerged that cannot be ignored."

Chen Ke is a little curious, a question that can't be ignored?

He looked at Fusu and said, "What's the problem?" ”

Fusu said helplessly: "Teacher, it is inconvenient to make this thing too big, otherwise it will be inconvenient to carry." ”

"After the appearance and characteristics and the place of origin are written on it, there is not much left."

"That way, it's hard to write down the numbers that the teacher said before."

"To put it simply, there are too many things to write."

"That's one of them."

"The second is ......"

"Although it is not easy to imitate this thing, Prime Minister Li Cheng is afraid that the people of the Six Kingdoms will have an affair with the local counties."

"So you want me to ask the teacher if there is a way to solve this matter."

Chen Ke pondered for a moment.

He really didn't think of the first question, because it wasn't a problem at all in the afterlife.....

But the second problem is not yet a good solution that can be completely solved.

It can only be avoided as much as possible.

Thinking of this, Chen Ke looked at Fusu and said, "The first question is simple, and the second question can only be avoided as much as possible." ”

"It can't be completely solved."

Fusu was a little surprised: "Are there any problems that the teacher can't solve?" ”

Chen Ke nodded: "Of course there is, I'm not an immortal, how can any problem be solved?" ”

He shook his head and said, "If I can solve all the problems, the one thing I have to solve is how people can not work, and still be able to get a fortune and enjoy fame." ”

Fusu's originally nervous mood was washed away by Chen Ke's words, and he couldn't hold back his laughter immediately.

"Teacher."

Fusu couldn't help but smile and said, "Just now you only said that the second problem can't be solved, so does the teacher have a way to solve the first problem?" ”

Chen Ke nodded: "Naturally." ”

He stood up, a slight smile on his face.

"I was negligent about that."

Chen Ke did not hesitate to directly admit his previous negligence, which was not a big deal for him.

He stepped aside and picked up a piece of paper.

There are a couple of very strange things written on the paper.

In Fusu's opinion, it is indeed very strange.

"Teacher, what do you mean by these things?"

"Looks so weird......"

Chen Ke looked at the numbers with a little nostalgia in his eyes.

He said without changing his face: "This is a counting method discovered by the sages of the Mo family, hidden in the past books of the Mo family. ”

Chen Ke said with emotion: "It's just a pity that those books are lost with the war, and I don't know where they went." ”

Fusu was also a little disappointed: "Except for the teacher, hasn't anyone read these books?" ”

Chen Ke was very surprised: "My teacher has also seen it, otherwise where would I go to see it?" ”

Fusu hurriedly raised his head, looked at Chen Ke and said, "Teacher, where is the ancestor?" ”

Chen Ke lowered his head: "The teacher has already gone immortal." ”

His face was sad: "This thing was also discovered before the teacher left." ”

"After you have time to hand it over to me, you will go."

After this patch was perfected, Chen Ke quietly changed the topic.

"Look."

“0，1，2，3，4，5，6，7，8，9。”

"These numbers correspond to zero to nine, these ten numbers."

"If you want to count up, you can stack it into two."

"If there is ten, it is one on the left, and zero is on the right, it is ten."

"Eleven is two ones together."

The decimal system has appeared in the Spring and Autumn Period and the Warring States Period, so at this time, Chen Ke's explanation, Fusu can easily understand it.

He looked at the string of numbers with a look of amazement on his face.

"How can there be such a clear and concise number in the world? The person who invented this method is simply admirable. ”

Fusu looked at Chen Ke with fanaticism in his eyes: "Teacher, what is the name of this law?" ”

Chen Ke replied: "The inventor of this thing did not take a name, but looking at the text used in its record, it is the Great Qin script, and it should be my Great Qin person." ”

"Why don't you call it Daqin numbers?"

After listening to this, Fusu muttered to himself.

Daqin numbers? Daqin numbers?

He sincerely admired: "Concise and clear, really worthy of a teacher." ”

"I'll hand over this number to Prime Minister Li Cheng, and let Prime Minister Li Cheng lead the way to the first one as soon as possible."

Chen Ke looked at the figure of Fusu running away, with a little emotion on his face.

Numbers, numbers.

He had forgotten about it.

Chen Ke turned his head, looked at the manufacturing department, and then looked at the sky in the distance, and couldn't help but smile.

"Being able to see numbers in Daqin can be regarded as something familiar again."

Chen Ke stretched and sat in the recliner.

"It's getting more and more like a familiar place for me."

Prime Minister's Office

Li Si looked at the paper in Fusu's hand, his face was also full of admiration and surprise.

He didn't expect that the problem that had plagued him for so long would be solved so easily.

"It's worthy of Chen Shaofu."

Fusu also sighed: "Yes." ”

"Thanks to a book that my teacher read, this kind of number was recorded."

"If not, how can something so amazing be revealed?"

He said with regret: "It's just a pity. ”

"The teacher said that in the war, I don't know where the book was lost."

Li Si looked at Fusu's emotional appearance and couldn't help but chuckle.

He looked at Fusu and asked, "Childe, do you really think that this number is what Shaofu saw from the book?" ”

Fusu was a little confused, and looked at Li Si a little confused.

"Isn't it?"

"But isn't that what the teacher said?"

Li Si let out a long laugh: "Hahahahaha, of course not!" ”
