Under the stunned eyes of Sun Xingdao and Yu Mouli, Wu Di quickly wrote down many strange characters on the paper that were crooked and twisted, making them very confused.

After writing, he put down the brush, clapped his hands, and said easily: "Oh, it's over!" ”

"Done?"

The two exclaimed at the same time, and Yu Mouli pointed to the strange characters on the paper, raised his eyebrows and said, "That's it?" ”

Then he sneered, "It seems that you are not deceiving!" You really haven't learned arithmetic! Three-year-old children's graffiti is better than yours! ”

Sun Xingdao was also a little confused, looking at the characters on the paper, and then at Wu Di with a calm face, he always felt that he was a fan of confidence.

"Little brother, what are you?"

Wu Di then remembered that they didn't know Arabic numerals at all, thought for a while, and said with a smile: "Shopkeeper Sun, this is my self-created character, which is convenient and easy to remember, and does not affect the accounting!" ”

Sun Xingdao listened, and glanced at the strange characters on the rice paper a few times, still a little confused.

This...... I don't understand it at all!

"Still a self-created character? Hehe, it's just a laughing person! ”

Wu Di glanced at Yu Mouli, didn't bother to deal with him, and directly began to report the answer.

"The first one, a total of fifteen taels and three hundred and twenty dollars!"

Sun Xingdao was stunned at first, and then snatched another account book from Yu Mouli's hand, compared it, and then was overjoyed.

"It's exactly the same, it's exactly the same!"

Yu Mouli pursed his lips disdainfully, thinking in his heart that it was just a blind cat that met a dead mouse, which made him blindfold!

When the second answer reported by Wu Di was also correct, Yu Mouli could continue to pretend to be calm, but when Wu Di said all the flow bills accurately, Yu Mouli's face was ugly!

And Sun Xingdao's face was filled with a smile that he hadn't seen for a long time!

Found a treasure, really found a treasure!

Wu Di looked at Yu Mouli's appearance as if he was mourning, and sneered in his heart.

"Mr. Yu, what am I talking about, even if you don't learn, you're much better than you, right?"

"Humph! The arithmetic is broad and profound, and the accounting is just the simplest, what's the big deal? ”

If the dead duck has a hard mouth, then I will convince you of losing!

"Yes, Mr. Yu can solve the problem in only one hour, it is really simple!"

"You-"

Wu Di deliberately emphasized the word "only", which could make Yu Mou angry enough, and he couldn't wait to rush up and fight Wu Di for 300 rounds - but he looked at Wu Di's body and looked at himself, and in order to avoid being beaten, he finally dispelled this idea.

"Since Mr. Yu also thinks this question is simple, it is better for Mr. Yu to come up with more difficult questions and let me see and understand it!"

Judging from Yu Mouli's ability to settle accounts in an hour, the arithmetic ability of this era is not much higher, and Wu Di is no longer worried, so let Yu Mouli let the horse come over, so that he can lose his heart!

"Well, that's what you said!"

Yu Mouli gritted his teeth and was ruthless, thinking that you sent it to the door yourself, don't blame my subordinates for being ruthless!

Sun Xingdao knew a lot about a certain Li, and knew that the moment his eyes narrowed, there would definitely be some tricky and complicated problems, and he sweated for Wu Di in his heart.

However, he didn't say much, because Wu Di's performance just now had already surprised him, and he was looking forward to the next showdown!

………………

Yu Mouli went back again, then walked in with a stack of rice paper, turned a few pages, pulled out one of them, and slapped it in front of Wu Di.

"Come on, you try this question!"

His expression was still a little proud, as if he had expected that Wu Di would not be able to solve this problem if he said anything.

Just like just now, Sun Xingdao was the first to come up, and after reading the content on the rice paper, he looked up at Yu Mouli, and asked with some uncertainty: "This question...... Was it the last question at last year's arithmetic conference? ”

"Exactly!"

Yu Mouli stared at Wu Di, extremely proud.

"It's a little too hard, isn't it?"

Sun Xingdao remembers clearly that the last question of last year's "Arithmetic Conference" was very difficult, and only Feng Ji Qianzhuang answered it in the end, even Yu Mouli himself had no way to take this question.

He's using this question to test others now - it seems a bit shameless!

"Let me see!"

It doesn't mean that a certain person answers, Wu Di can't wait to come forward, wanting to see how difficult the problems of this era are!

My brother also participated in various math competitions when he was in school, so he shouldn't be compared to people of this era, right?

With apprehension, curiosity and a little bit of piety, Wu Di looked at the rice paper, and when he finished reading the topic, the whole person was stunned.

"Isn't it too hard?"

Seeing this, Sun Xingdao hurriedly asked.

Difficult?

What a ghost!

The moment he saw this question, Wu Di's IQ seemed to have been insulted, so it's no wonder if he wasn't stunned!

This is the problem of this era?

It's a bit child's play, isn't it?

It is no exaggeration to say that in his time, elementary school students did not bother to do this question! Don't look at the primary school students of the Great Celestial Empire who eat chicken kings every day, there is no problem in dealing with this kind of problem!

Wu Di is a top student from a key university, and doing this kind of question does have a feeling of being demoted.

began to comfort myself in my heart, it seems that if I take out my primary school level, I can be rampant in the arithmetic world of this era!

"Is it difficult? It's not difficult! ”

Wu Di spread his hands with a relaxed expression.

"That little brother, this is ......"

"I just didn't expect that Mr. Yu searched for a long time, and found such a simple question, and he was a little disappointed......

At this time, Wu Di really realized the joy of pretending to be forced, no wonder so many people like to pretend to be forced to slap their faces, because it is really cool!

"Hehe, who wouldn't say big words? If you say it's simple, then you can solve it! ”

Yu Mouli has already learned the methods of Wu Enemy, the cannon hit with his mouth is called a sound, if he is serious, he will lose, so he simply doesn't say more, his hands are on his waist, waiting to see a good show!

Wu Di rubbed his hands, thinking that the next moment was to witness the slap in the face!

Picking up the pen, I glanced at the title on the rice paper again, and saw that it was written like this.

[A coachman driving a carriage with five people sitting on it.]

And each of these five people carried five more bags, each of which contained five big cats.

Each big cat carries five kittens, and each of the five kittens carries five mice as rations.

Q: How many legs are there in this question? ]

(How many legs, cuties?) If you can't answer, give me a vote! ）
