Tianshan Tong Mao, formerly known as Tong Yan.

She is the leader of the mathematics teaching and research group of the fourth middle and high school, and she is forty years old this year, because she has a good appearance, and she looks like a twenty-seven or eighteen-year-old woman, and everyone calls her "Tianshan Tongma".

The most critical thing is that she is in her 40s, and like Li Luogan, she is still unmarried.

Of course, Kong Shucheng can't share all the information about "Tianshan Tong's grandmother" with Li Ruiyun. Because there are some rumors, in fact, they are also made up by Mao Nan, the moisture is too high, and the color saturation is too high, so it is not appropriate to relay them.

In short, Mr. Tong Yan is in the fourth middle school, and he is definitely a legendary figure.

Because she teaches well and has Zhao Yazhi-like rejuvenation techniques, she has invisibly gained a lot of fans. It is said that Vice Principal Wang quarreled with his wife several times, all because he was thinking about Teacher Tong Yan.

.........

After Kong Shucheng finished telling the legends of Teacher Tong Yan, he found that Li Ruiyun had already listened attentively.

"Hey, senior sister, I told all the secrets of Tianshan Tong's grandmother, didn't you promise me just now that you wanted to tell me the secret about your uncle?"

Li Ruiyun nodded: "If I guessed correctly, the teacher Tong Yan you mentioned used to be my uncle's girlfriend." ”

"Ah.........?"

"Many years ago, they both went to university in Beijing, and they both had an unforgettable experience. Later, for some reason, the two of them didn't end up together. But even so, they both love to listen to the same song, which is "The Sound Of Silence". Therefore, I dare to infer 100% that the two of them are still unmarried, and they may not be able to fit anyone else in their hearts. There is a poem that says, once the sea was difficult to water, but Wushan is not a cloud. ”

Speaking of this, Li Ruiyun's emotions began to be a little excited.

Kong Shucheng nodded thoughtfully: "No wonder, your uncle said that he has no fate with me, it turns out that he only has a fate with our teacher Tong Yan." Oh yes, what is the contradiction between him and Teacher Tong Yan?"

"I don't know. ”

"The reason why your uncle is unwilling to be my teacher is because he hates the house and Wu. ”

"This possibility cannot be ruled out. Li Ruiyun frowned: "Kong Shucheng, do you have to find my uncle to tutor in mathematics?

"No, I can't. ”

"Why?"

"Because, I think your uncle is handsome. ”

"Well, in that case, then I'll tell you a little bit more about Uncle Di's secret. ”

"Say it quickly!"

"Kong Shucheng, if you want to be my uncle's student, you must have the strength to break his 'entry three-board axe'. ”

"Beginner three-plate axe?"

"Yes. According to my understanding of my uncle, if you want him to tutor you in mathematics, then you have to have a place where he will impress you. To tell you the truth, my uncle has also tutored several middle school students, and two of them have entered the national team of the Olympiad. ”

"I'm rubbing, this is awesome? Will I be the third to enter the national team of the Olympiad?"

"As I said earlier, if you want to be his student, you have to be able to break his 'three axes'. ”

"Hurry up and say, which three axes?"

"First, your mental arithmetic ability should be on par with my uncle. In other words, even if you lose, you can't lose too much. ”

"Uh........." Kong Shucheng suddenly felt weak.

"What, Kong Shucheng, do you feel that your mental arithmetic ability is not good?"

"It's not that it doesn't work, it's very bad. In addition to the ninety-nine multiplication formula, I can be a little confident, whoever compares mental arithmetic with me, I will definitely die. ”

"It's impossible, right? I see your performance at the ancient poetry conference, you don't have such a melon skin? Could it be that you opened a plug-in?"

"That's right, is the Xueba system a plug-in?"

"Die, I'm talking to you about business!" Li Ruiyun glared at Kong Shucheng fiercely.

Kong Shucheng: "........."

"Classmate Kong Shucheng, since your mental arithmetic ability is not good, you can only compete with my uncle for fast memory. ”

"Uh........."

"What's the matter, your memory is not good?"

"It's not that it can't be done, after all, I'm also the one who won the 'Mayor's Cup' ancient poetry contest. ”

"yes, that's what it sounds like. Li Ruiyun felt a little relieved.

Kong Shucheng: "Senior sister, what is the state of your uncle's memory?"

"Well, he's 42 years old this year, and his memory is starting to decline. ”

"That's good, if you say that, I will have the confidence to pass the level. ”

Kong Shucheng poked his hand excitedly, and was about to knock on the door to challenge Li Luogen's memory, when Li Ruiyun suddenly grabbed him from behind: "Hey, Kong Shucheng, what are you going to do?"

"I'm going to challenge your uncle's memory. Didn't you just say that as long as I can break his introductory axe, I will be qualified to be his student?"

"Hey, classmate Kong Shucheng, before you go in, you can compare with me. ”

"I don't want to be a teacher from you. Kong Shucheng glanced at Senior Sister Li with disdain.

Li Ruiyun: "My uncle's quick-mature memory is so much higher than mine, you can only challenge his old man if you PK me first." ”

"Ah, so? you......... You're amazing, aren't you?"

"Actually, my memory is average, mainly depends on your level. ”

"Okay, let's get started. But how can this memory compare?"

"It's simple, just follow my uncle's rules. ”

As he spoke, Li Ruiyun tiptoed out two playing cards from a drawer.

Kong Shucheng smiled: "Is there a PK between the gambling king Gao Jin and the gambling saint Li Ruiyun?"

Li Ruiyun rolled his eyes: "Don't talk nonsense, let's start practicing!"

The two began to shuffle!

After a few seconds.........

Li Ruiyun handed over the first shuffled deck of cards to Kong Shucheng: "The rules of the game are very simple, the two of us can only stare at a deck of playing cards in our hands and watch them seriously for ten seconds. After ten seconds, whoever memorizes more cards wins. ”

Kong Shucheng snapped his fingers: "Simple." ”

The timer begins.

The two looked at the cards.

Ten seconds later.

Li Ruiyun immediately put away all the cards and asked, "Kong Shucheng, how many cards have you memorized?"

Kong Shucheng smiled: "There should be a lot of more." ”

Since the upgrade of the Xueba system, he thinks that his memory has also improved very rapidly. If it had been before, he would probably not have remembered ten cards in ten seconds.

Li Ruiyun nodded, and took Kong Shucheng's playing cards in his hand: "Next, please start memorizing cards." ”

"3 of hearts, 7 of spades, Q of squares, 9 of diamonds, Wang of bets, 2 of spades, King of clubs, 10 ......... of hearts"

Kong Shucheng held his breath and said 17 playing cards like a mountain.

Li Ruiyun frowned: "It's all over the back?"

"That's right, I'm done!"

"Kong Shucheng, just now you only memorized a total of 19 cards? Moreover, the 16th and 19th cards were both misremembered, so you effectively memorized a total of 15 cards. ”

"Uh......... In 10 seconds, I memorized 15 cards, which seems pretty good, right?"

Kong Shucheng said this, it's really not floating. People, don't always compare with others, just compare with yourself. In ten seconds, he can remember 15 playing cards at a time, which is indeed his upper limit. In other words, he was a quasi-scumbag in the era, and it is estimated that he can't even remember 8 photos.

“.........”

Senior Sister Li Ruiyun didn't speak, but quietly hid another playing card in her hand.

Kong Shucheng smiled slightly, thinking: Hehe, senior sister should have retreated in the face of difficulties, right? As the saying goes, good men don't fight with women. Wasn't I a little too sharp?

I'm thinking about it.........

Li Ruiyun shook his head suddenly: "Kong Shucheng, I suggest you, let's go." ”

"What do you mean?"

"You're sure you won't be able to pass my uncle's introductory three-plate axe. ”

"Ah.........?"

Kong Shucheng was slightly unconvinced, and asked with a flat chest of ribs: "Senior sister, do you think I have an average memory?"

"It's not average, it's very bad. ”

“.........”
