This person really has no way to save face.

The few questions that Zhang Shangshu took out were all very classic math problems, which were the questions that Song Beiyun wrote at the end of the introduction to mathematics to motivate Zhang Qing.

This needs to be solved using algebraic equations, which is about the same as the difficulty of the third year of high school, and of course it is incomprehensible for entry-level people, and algebra is obviously not something that Master Zhang has learned, so I think it should be a whole night of hard thinking and meditation but I can't solve it.

But you have to come over and ask directly, how can you hold this face, you can comprehensively suppress Song Beiyun regardless of age, qualifications or official position, let him ask a scholar without shame, sorry...... He couldn't.

However, these questions looked like a fish in his throat, and he was very sure that if he couldn't get the solution to these questions today, he would definitely have no taste or sleep, so he simply changed his way and found Song Beiyun in his own way.

"In this way, my lord, I will explain it to the adult, and Lord Zhang will check it for me and check the authenticity."

"Yes."

Song Beiyun took out a pencil and wrote on the paper, Zhang Shangshu watched the process of his writing, but the more he looked at it, the more confused he became, and there were more and more ghost talismans on it......

"Here, let's bring in ......," Song Beiyun explained to him while writing: "We have to take this factor into account, so here is not 2 but root number 2." ”

After a few questions, although Song Beiyun tried to write in detail, Zhang Shangshu was still unable to understand, and finally Miss Qing jumped out and shouted: "Master, if you write like this, my father can't understand it." ”

This childish remark made Zhang Shangshu's old face flush with shame, but he quietly picked up the cup and took a sip of tea: "It's nonsense, how can I not understand the Shangshu of the Ministry of Works." ”

"Then tell me what X stands for, what Y stands for, and what Y square represents." Zhang Qing didn't relent: "Say it! ”

Zhang Shangshu snorted coldly: "If you say it, then what does it mean." ”

"If you don't understand, you don't understand, it's not a shameful thing, why do you don't know how to pretend to understand?" Zhang Qing looked at Zhang Shangshu with a confused expression: "Master said, knowing is knowing and not knowing is not knowing." ”

Song Beiyun turned around: "Zi said!" ”

Zhang Shangshu was speechless for a moment, ashamed, and glanced at Zhang Qing a few times angrily, but he was a little restless.

"Master Zhang must understand it, otherwise he wouldn't have come to inspect me." Song Beiyun got up at this time and said: "It's just that my method of solving the problem is deviant and doesn't play cards according to common sense, and Lord Shangshu is naturally angry." ”

"Master, you ......"

Miss Qing was about to continue talking, but Song Beiyun grabbed the back of her neck and threw her outside the door and closed the door......

"Master Shangshu, she's gone."

Zhang Shangshu let out a sigh of relief, then pointed to the numbers on the paper and said, "What is this substitution?" ”

Song Beiyun likes to pretend to be forced, but he never pretends to be forced in terms of knowledge, whether it is an old madman or a Fu King, he is very humble about what he is lacking, and he is also very patient where people don't understand, so he sat there and began to explain to Shangshu little by little what algebra is.

I have to say that a big man who can be a high-ranking official like Shangshu is definitely top-notch in terms of IQ, and when Song Beiyun explained, he found that he had almost eaten the entire reference book in one night.

Not to mention anything else, Song Beiyun can't compare with this hard work alone, if Zhang Shangshu is a modern person, he will probably be the same as playing in all kinds of prestigious schools. The ability to comprehend, penetrate, and logical is all excellent.

In front of such a person, Song Beiyun also gave a lecture easily, and Zhang Shangshu would ask carefully and carefully several times if he didn't understand.

This came and went, and before I knew it, it was already time for lunch, but the algebra course was only less than one-tenth of it.

"Hmm...... It's not too early, Lord Shangshu will have a light meal at the Imperial City Division today. ”

Before he could nod, the door opened, and Miss Qing stood outside holding a bowl bigger than her head and shouted, "Daddy, Master, it's time to eat." If you don't eat that braised chicken, you will be eaten up by those skins. ”

"Don't worry." Song Beiyun got up and smiled: "I can't eat it all." Master Zhang, move? ”

Zhang Shangshu was not polite, full of style, and a leader came to the dining hall under the leadership of Song Beiyun. And today, because of Shangshu's visit, the food is better than in the past, chicken, duck and fish are all available, and there are some winter mountain delicacies as vegetables, and it is also painstaking to think of it.

"Please invite Mr. Zhang into the inner hall for dinner." Song Beiyun said politely: "It's noisy outside, so as not to disturb the adults." ”

"This official is not such a squeamish person, and he can be regarded as having endured hardships when he was studying." Lord Zhang refused Song Beiyun's invitation, and walked to the place where he was cooking and took a look: "Lord Song, the food in this Imperial City Division is very good, and the daily expenses are not small, right?" ”

"Brothers, if you can't eat well, how can you have the strength to do things for the court."

"Well, Rao has some sense."

Zhang Shangshu is also just going through the motions, after all, the funds of the Imperial City Division are not from the Ministry of Industry, that is, they are affiliated, and they are clearly different systems, but he can't control them.

After eating, Zhang Shangshu and Song Beiyun sat opposite each other and ate, he looked around and nodded lightly: "I didn't expect that Lord Song was not very old, but he was well organized." Even these splashes can be taken care of, and they will be the pillars of the court in time. ”

"Thank you, Lord Zhang, for your compliment."

"In a few days, I will go to the official family and tell you that you will come to the Ministry of Industry after the year. Don't you regret it? You must know that the Ministry of Industry is a clear water yamen. ”

Song Beiyun's eyes lit up at that time, he got up and hugged his fists and bowed: "Thank you, Lord Zhang." ”

"It's not enough to worry about, but why does X need to be cubic?"

Some people are martial arts idiots, some people are nymphosos, some people are music idiots, then naturally some people are learning idiots, this Zhang Shangshu can really be said to be born at the wrong time, his intellectual curiosity is the most vigorous of the first-grade and second-grade masters that Song Beiyun has ever seen, and he is also the one with the most respect for knowledge.

Maybe there is a natural closeness between science and engineering, anyway, Song Beiyun likes this little old man, and this little old man seems to be more satisfied with Song Beiyun.

And this person's biggest problem may be his good face, but it's no wonder that he, after all, he is sixty years younger, let such a person be ashamed to ask a person who is not much older than his daughter, as long as he is not a saint, most people can't do it, not to mention that he is a scholar! It's a ministerial-level boss, and when he goes down to the place, he is the kind of person who has to go out to greet the history of the three pins.

In the next day and a half, Song Beiyun's time was all spent on this little old man, he soaked in Song Beiyun's office all day long, in order not to affect Song Beiyun's office, he even squeezed a small table with his daughter to do questions there, and the two discussed it from time to time.

"Master Zhang, I'm going back to my hometown tomorrow to rest, maybe I'll see you again after the New Year."

On the last evening before leaving, Song Beiyun sent Master Zhang and Miss Qing to the gate: "I also wrote out the exercises during the rest of the bath, you can have a good time." ”

Zhang Shangshu twisted his beard and chuckled: "That's not easy. ”

"Less bragging." Miss Qing snorted: "Today's question, five out of seven are wrong, and they are all low-level mistakes." ”

Zhang Shangshu was immediately silent, the death hole of this little old man is the daughter of this monster in the family, it is useless at all.

And after Zhang Qing finished talking about his father, he turned his head to look at Song Beiyun and said pitifully: "Master, you have to come back early......

"Hugh Mu is over and will return." Song Beiyun said with a smile: "Okay, it's not far away, Zhang Shangshu walked slowly on the road." ”

The father and daughter left, and Song Beiyun heard Zhang Shangshu reprimanding Miss Qing from afar, saying that she was embarrassed to say that kind of thing, she couldn't even memorize a formula after studying it for so long.

"What a strange pair." Yan Shu walked out of the door: "The past two days have made me so angry that I dare not come out." ”

"Eager to learn."

"But speaking of which, this Shangshu was also saddled with the name of a prodigy, with quick thinking but love arithmetic, if he is right with poetry, I am afraid he is no less than Li Taibai. But it's also strange, as far as you are concerned, you are afraid that idlers will not be able to accept it, and they will think that you are deviant and subvert the classics. ”

"People have their own aspirations, and some things rely on talent, besides, he is not a Confucian, his thinking is obviously miscellaneous. Look at you, isn't it said that people are prodigies if they are so wasteful? Song Beiyun turned his head: "Tidy up, go home for the New Year!" ”

"Alas, I'm really a genius!" Yan Shu chased after him reluctantly: "You can't talk nonsense. ”

"Okay, okay, you don't have to send me tomorrow, it's a month anyway."

"Do you think I like you so much? Leave early. Yan Shu looked at him with his hands behind his back: "In a few days, my family will come from my hometown to spend the festival with my grandfather, have you arranged your shift?" ”

"Hmm."

"Be careful when you go back." Yan Shu whispered: "In that place in Jiangxi, white lotus is rampant. If you are the number one public enemy, if you let them find an opportunity, they will not be spared. ”

Song Beiyun's brows suddenly frowned: "If you don't remind me, I really forgot about this and left." ”

After he left the Imperial City Division, he went straight home, and there was no one else in the house except Xiaoyu, Zuo Rouqiaoyun was pressed in the mansion by the Dingguo Duke of Xiu Mu and couldn't go out, and Jin Ling'er didn't have time to leave the palace. Clever words and pretty people went to buy New Year's goods, so the house was depressed.

"Xiaoyu, go back to your hometown with me tomorrow for the New Year."

"Huh?" Xiao Yu was stunned for a moment: "This ...... Really? ”

"That's nature." Song Beiyun laughed: "Leave you here alone?" By the way, you will go to Lao Wang's and ask him to borrow ten good hands. We went on the road together, and all their expenses were mine. ”

"Lord Song is worried about White Lotus's revenge?"

"The hands of the family are powerless, so they must be more careful." Song Beiyun patted Xiaoyu's head: "After eating, you will go." ”
