On the second floor of Wangjiang Building, at this time, all the diners have already shifted their attention, and they are all looking at the two sides of the competition with interest, looking forward to the staging of a good show.

"Huang Jinquan, Tong Yuan, Lin Shuhong."

Liu Jin looked at the three of them, then thought for a while and asked, "Since you are a scholar, you should know the six arts of a gentleman, right?" ”

"Of course, the so-called six arts of the gentleman refer to the rites, music, archery, royal, calligraphy, and mathematics, from "Zhou Li ~ Baoshi": raising the country to the Tao, is the six arts of teaching: one is five rites, two is six music, three is five shots, four is five royal, five is six books, six is nine numbers."

Hearing Liu Jin's words, Tong Yuan was the first to stand up and answer, not only to tell the six arts of the gentleman, but also to memorize the source.

"Not bad, since you claim to be a gentleman and a disciple of a saint, then let's choose a few from the six arts of a gentleman to compare, compare three games, two wins in three games, and ask each other questions, how about it?"

Liu Jin nodded, and then proposed.

"Yes~"

As soon as he heard that Liu Jin was going to compare with the six arts of a gentleman, Huang Jinquan felt a pimple in his heart, this person is really uneasy to play the cards, but now it is difficult to ride a tiger, and he can only bite the bullet and continue.

"Etiquette, archery, music, royal, books, and mathematics, there is obviously no way to compare shooting and royalty here, so let's compare them first."

"The topic is very simple, the rabbit and the tortoise are 1,000 feet apart, and they walk towards each other at the same time, the rabbit is moving towards the turtle at a speed of 35 feet per moment, and the tortoise is moving towards the rabbit at a speed of 15 feet per quarter, when and where will the rabbit and the tortoise meet?"

Liu Jin thought about it first, if this topic was placed in the future generations, primary school students would do it, but the readers of this era basically revolve around the Four Books and Five Classics, even if it is the simplest arithmetic problem, Liu Jin feels that the topic may not be able to be calculated.

When Huang Jinquan, Tong Yuan, and Lin Shuhong heard this, they were dumbfounded, this is a rabbit and a turtle, and they are running with each other at the same time, let alone seen it before, they have never heard of it, and they don't know how to calculate it at all.

After listening to Liu Jin's question, the other people on the second floor also began to calculate silently in their hearts, and some businessmen calculated it immediately in their hearts, this kind of problem is still very simple, as long as they learn arithmetic, they can calculate it, it is not difficult.

"Rabbits? Turtles? ”

"1,000 feet apart, when and where will we meet?"

The young man also counted carefully with his fingers, and soon, he couldn't help frowning his eyebrows as he counted and calculated.

"I... We can't figure it out. ”

After a few minutes, Huang Jinquan, Tong Yuan, and Lin Shuhong looked at each other, and they all saw the meaning in each other's eyes, and they could only say to Liu Jin with a hard head.

"It's so easy to figure out, and I don't know what books you're reading."

Liu Jin smiled, he was worried that they would be able to calculate it, but now it seems that the imprisonment of the eight imperial examinations on the minds of scholars is really powerful, and they can't even do such simple arithmetic, obviously they haven't learned at all, and they are probably the kind of scholars who say that they are every day, otherwise it is impossible to calculate such a simple arithmetic problem.

Of course, to deal with the three of them, Liu Jin has a way, if this topic is calculated, Liu Jin will say that the other party still has some ability, and then deepen the difficulty and release the more difficult arithmetic problems, I believe that they will always be able to stump them.

I just didn't expect that such a simple arithmetic problem would not be calculated, but it saved a lot of brain cells.

"You~"

Hearing Liu Jin's words, Lin Shuhong became even more angry, staring at Liu Jin, but soon held back.

"You, what you, let's get the question."

Liu Jin smiled and motioned to the other party to ask the question.

Huang Jinquan, Tong Yuan, and Lin Shuhong, you look at me, I look at you, I don't know how to solve the question for a while, Tong Yuan looked at the other two, thought about it and said: "I'll come up with this question, it just so happens that I once read a strange book." ”

"I'm sorry for the boy."

Huang Jinquan nodded and said.

"Brother Liu, I don't know if you know Jiugongge?"

Tong Yuan looked at Liu Jin, smiled and asked.

"Of course the nine-square grid knows, isn't it just 9 grids divided by tic-tac-toe, just ask the question."

Liu Jin nodded and replied, looking light-hearted.

"These nine palaces are the art of Qimen Dunjia, now please fill in the nine numbers from one to nine into the nine palaces, so that the sum of the nine palaces is horizontal and vertical, and the sum of the diagonal is fifteen."

Tong Yuan said the nine-palace arithmetic problem he saw in the book, in his opinion, this topic is definitely very difficult, at the beginning, he thought about it for a long time and didn't come up with an answer, and finally read the answer in the book to know how to lay it out.

"Nine Square Grid~"

As soon as Tong Yuan's words fell, the entire second floor was also silent, and everyone was silent again, and began to calculate continuously, some people even put out a nine-square grid on the dinner table, and kept calculating, and when the layout was wrong, they kept laying out again and again.

"It's easy~"

The young man's table, the young man's father couldn't help but smile when he heard it, he had also read this in a book, so he naturally wrote it down, and thought it was very simple, but it was Liu Jin's topic, he had never learned arithmetic, and he hadn't calculated it yet.

"No, the horizontal line is right, the vertical line is not good, the first line is right, and the second line is not right."

The young man took two pairs of chopsticks on the table and laid out the tic-tac-toe, and began to calculate it continuously, shaking his head again and again while laying it out, obviously there was no way to lay it out at all.

"Brother Tong is good."

When Lin Shuhong heard this, he silently calculated, and immediately gave Tong Yuan a thumbs up and said.

"I'm also picking up people's teeth, and I saw it in a book."

Tong Yuan smiled and said modestly.

"This question is difficult, it will be calculated at all for a while and a half, this nine-house chart has endless changes, and it is difficult to answer correctly if you don't know the answer."

Huang Jinquan also said with a smile, he had seen this topic before, and he tried to calculate it at that time, but he couldn't calculate it, he was more confident in this, as long as the other party hadn't seen this, it would definitely not be calculated, and that game could be regarded as a draw.

"Hehe, you're embarrassed to take out this kind of pediatric topic, it's really looking down on me."

As soon as Liu Jin heard it, he was happy in his heart, this topic is also a topic for primary school students, primary school students will, and there are more difficult sixteen square grids, thirty-six palaces, and so on.

"Listen, the nine palaces, that is, two or four for the shoulder, six or eight for the feet, three on the left and seven on the right, one on the nine, five in the center, if you are interested, you can count the sixteen squares."
