After explaining the terms such as balance, mass, and volume to his granddaughter, Old Man Kong continued to bury his head in the pile of old papers, intending to find a correct algorithm from it that could solve the disgusting twelve balls.

the obnoxious pool keeper, who fills the water while releasing it; Xiao Ming, who has amnesia, always asks the puppy to fetch things; horse-drawn carriages that travel opposite each other; a horse-drawn carriage with its back to it; A horse-drawn carriage ...... fast and slow.

Old man Kong didn't know how Li Chengqian's head grew, why did he come up with so many messy things to calculate, in his opinion, these things were useless at all, and they were a complete waste of time.

But there is no way, if you want to use his textbooks, you have to count his questions, which is matching, otherwise those Mengxue questions will be too simple for students, and it often won't take much time to get them done, which will show that Mr. is very faceless.

"Grandpa, grandson is done." About half an hour later, Kong Wen put a piece of paper full of words on Kong Lao's desk.

"Done?" Kong Yingda raised his head, his eyes flashed with confusion, and after a while, he repeated in surprise: "Are you done?" ”

"Hmm. It's all written on paper. Kong Wen pointed to the paper on the table and said.

"Oh, grandpa, look." Kong Yingda, who had a pair of presbyopia, picked up the paper on the table and looked at the lines of graceful letters written by her granddaughter quite laboriously.

After a while, Old Man Kong's eyes became brighter and brighter, his free hand was gesturing in mid-air, and finally he slapped his thigh hard, regardless of whether his granddaughter could stand it or not, and shouted: "Great, great." ”

"Grandpa! Grandfather! The little girl was startled by Lao Kong's crazy appearance, and called out repeatedly, afraid that her grandfather would lose his mind and go crazy, and her sin would be great.

"Oh, grandpa is happy, happy." After being called several times, Old Man Kong finally came back to his senses a little, took the paper in his hand embarrassedly, and said to his granddaughter: "Grandpa wants to go out, Wen'er think about what she needs, and when grandpa comes back, we will buy it together." ”

After that, without waiting for Kong Wen to say anything, she took off her robe and clothes, trotted out of the door, and disappeared outside the courtyard wall almost in a blink of an eye.

"Your Majesty! Your Majesty! Outside Li Er's study, the wheezing old man Kong couldn't wait for the waiter to spread the word, so he simply screamed.

"Aiqing, why are you so anxious?" Li Er looked at the sweaty appearance of the old man Kong, so he let him gasp now, and asked the maid to bring tea.

"Your Majesty, this question has been solved." Lao Kong took out the piece of paper written by his granddaughter from his arms and asked the chamberlain to hand it over to Li Er, and at the same time took his granddaughter's credit for himself very shamelessly.

"Kong Qing ......" Li Er took the white paper handed over by the chamberlain, glanced at it, put it aside, tapped his fingers on the table, and said with a look of embarrassment: "Kong Qing is a handsome man in the Tang Dynasty for me, it will take three days to solve this problem, what will happen if other mediocre people do?" Has Kong Qing thought about it? ”

For a moment, Kong Yingda was like being struck by lightning, and the whole person froze on the chair, and there were only three words in his mind: fooled!

In fact, from the moment Li Chengqian took out the question, Kong Yingda should have known that he had lost, because what they were arguing about was not the answer to the question at all, but the time to answer the question.

However, Lao Kong was confused by Li Chengqian at that time, and after getting the problem, he drilled into the problem with all his heart, completely ignoring the key to the matter.

Now that three days have passed, it is superfluous to discuss anything, and Li Er's heart has confirmed what Li Chengqian said: There is no point in continuing to write, even the teacher doesn't understand what is written in the book, how to teach students?

Lao Kong, who was like a mourner, didn't know how he came out of the palace, and returned home in a trance and shouted at the sky: "Liar! "I fell headlong, as I said in the recital a few days ago, and I couldn't afford to be sick.

The hard-pressed Li Chengqian had another problem, and he had a big deal, and the charge of being angry and fainting the important ministers of the court was put on his head by the old man, claiming that if the old man Kong traveled westward with a crane, then the blue brick and tiled house in Zongzheng Temple would definitely let him live in a good time.

Li Chengqian didn't know what Lao Kong's illness had to do with him, and even vaguely felt that it was a good talk to calculate the problem and ride the crane to the west.

But after all, I should visit or go. On a drizzly afternoon, a depressed Li Chengqian came to Kong Yingda's house with the old man's reward.

Then he found a very embarrassing thing, Kong Wen's little girl was really glaring at him.

There's no way, let's go hard, after giving Lao Kong a teacher salute, Li Chengqian hugged Kong Wen with a fist: "Little brother is smart, I've seen the second sister." ”

In Kong Wen's cold snort, Lao Kong lay on the bed and asked in confusion, "You two know each other?" ”

"Oh, that's right." Li Chengqian didn't wait for Kong Wen to answer, and said first: "When the student was in Qingzhou, I was fortunate to meet Brother Mingli, and at that time I was also a brother with a different surname, so I called Kong Wen's little lady and second sister." ”

Old man Kong listened to Li Chengqian's explanation, turned his head and glared at his granddaughter fiercely, the eldest grandson Kong Wen Kong Mingli has always been in Chang'an, and it is completely nonsense to say that Qingzhou is worshipping, this is obviously the granddaughter going out to mess around in the name of her brother.

But now is not the time to talk about this, since Li Chengqian didn't find out, it is impossible for Lao Kong to expose his granddaughter's secret in person, otherwise who knows if there will be other troubles.

Lao Kong didn't mention it, Li Chengqian naturally didn't mention it, at the beginning, he pretended to be another identity to worship Kong Wen, and at that time he also vowed to introduce Kong Wen and the 'prince', but now he showed his true face in front of the main master, and the embarrassment almost made him embarrassed.

Kong Wen's little girl prides herself on being smart, and she thinks that she will not tell the fact that she was deceived by Li Chengqian, since Li Chengqian stupidly didn't recognize her, then it's better to hide it, otherwise to put it bluntly, the little girl's face will be lost.

In this way, the atmosphere in the room was very strange, Lao Kong thought that Li Chengqian did not recognize his granddaughter, but he did not know that he was using a fake identity to worship, and he was afraid that he would commit the crime of deceiving the king by telling the secret, so he decided to conceal it;

Kong Wen also thought that Li Chengqian didn't recognize herself, but it was a fact that she was deceived by Li Chengqian, so the little girl didn't want her grandfather to know that she had been deceived, so she also decided to hide the secret.

And Li Chengqian, the only one of the three who understood, had to hide the fact that he actually knew everything in order not to make the atmosphere even more embarrassing.

Three people, three minds, everyone thinks they have deceived the others, and they are all hypocritically perfunctory to the other two.

For a while, the atmosphere in the room could only be described by a modern popular word: embarrassing open the door - embarrassing home!
