Hearing Sang Qingqiao's narrow tone, Sang Qingyu didn't know whether he was angry or shy, so he slapped him on the head casually, "Don't talk nonsense to Ning Ning, she is the last time I went to buy the four treasures of the study for Ning Ning and them." ”

"Oh, it's the day the second brother's eyes became jet black!?" Ning Ning suddenly realized, when his brother came back that day, he was still angry, why is his brother's face red now!? By the way, it must be angry!

Hearing Ning Ning mention it, Sang Qingyan didn't understand it even more, the second brother was still a little angry when he came back that day, and he couldn't tell how his eyes were beaten like that, but he vaguely said that it was related to a girl, he thought that the second brother was angry with that girl, why is that girl admired now!?

He looked at Sang Qingyu's blushing appearance at this time, could it be that the second brother liked that? The more you fight, the more emotional you get!?

Sang Qingyu glanced at Sang Qingyan's confused expression with a bit of understanding, and was even more embarrassed, "Big brother, why are you even cranky!?" ”

"Me? What do I think!? It was rare to see Sang Qingyu like this, and Sang Qingyan couldn't help but tease him a little.

"That's it, it's ......" Sang Qingyu stammered and couldn't say clearly, if he wanted him to say that his brother thought that he was a young man, how could he say it, not to mention that there were still Ning Ning and the two children of the third brother, this matter was not like what Sang Qingyan thought at all.

The reason why he advanced Qian Fang was mostly because he was not convinced, hmph, he couldn't count Qian Fang in accounting, so let her admit defeat in another way.

That day, Sang Qingyu went to the town and said that he wanted to buy the four treasures of the study, and the vendor, who had already been familiar with him, took him to the study that was said to be about to go out of business.

As soon as I entered the study, I saw red posters with reduced prices everywhere, and the owner of the study should have sold all the things in this study cheaply, but the prices were different, even if it was Sang Qingyu, I couldn't tell which one was cheaper.

It happened that the money boss of the study went out at that time, and Sang Qingyu was in a hurry to buy the things back, so he screamed a few more times, which attracted Qian Fang to come out to greet him.

Sang Qingyu saw that it was a girl at the beginning, but he didn't pay much attention to it, just casually said what he needed, but as soon as he finished speaking, the girl had already put everything he wanted in front of him.

"Take it, it's the best deal to buy it like this." The girl's voice was faint.

"A good deal!?" How can anyone sell things to attract customers with a good deal, shouldn't they sell as expensive as possible?

Sang Qingyu didn't believe what she said, and just as she was about to count, she heard the girl speak again, "Don't forget it, after the price is cut, there are a total of eighty-nine copper plates." ”

Sang Qingyu glanced at her and continued to count, and sure enough, as the girl said, it was really eighty-nine copper plates.

Hearing her calculate so smoothly, Sang Qingyu felt more and more that there was some trick hidden in it, so he casually took out one of the brushes and replaced it with the other.

But as soon as he took it, the girl immediately said, "If you change that brush, it will be ninety-four after the price is cut." ”

Sang Qingyu raised his hand and looked at it, and said with a smile: "Girl, I'm afraid it's a mistake, the brush I'm holding now is five copper plates cheaper than the one just now, why is it so expensive?" ”

"The previous brush was full of five minus ten copper plates, and now you take out one, and there are only four left, can't you subtract ten copper plates, even if you replace this cheap one, won't it cost five more copper plates?" The girl glanced at it and said coldly.

This series made Sang Qingyu a little dizzy, and it took a while to realize that what the girl said was right.

But he didn't admit defeat in his heart, and casually changed a stack of papers, "What about now?" ”

"It's still twenty wen more expensive than just now, and if you buy it like this, it's one hundred and nine wen." The girl seemed to blurt out.

"W-how could this be!?" Sang Qingyu looked at it carefully just now, the price of these rice papers has also been reduced, even if it is changed, the price should not change.

"The sum of those rice papers and brushes before can be subtracted by five cents, but the rice paper you changed just now is not the same as the brush." The girl said lightly: "So as I said just now, that is the most cost-effective." ”

The girl said, raising her eyes to look at Sang Qingyu, as if she was a little provocative, as if to say, you try, if you can be cheaper than what I calculated, you win.

How could Sang Qingyu, who boasted of being the most calculating, endure this tone, besides, there were hawkers around him who were watching the excitement, how could he not admit defeat!

But I was impetuous, and after looking around, I couldn't find a suitable thing, and the girl said again at an inopportune time, "Isn't the guest in a hurry to go back?" ”

Is it just throwing in the towel!? Sang Qingyu was in a hurry, and casually pulled out a scroll from a high place, "Using this to replace the brush should be more cost-effective than what you just calculated, right!?" ”

He didn't look at it and moved casually, so naturally he didn't notice that there was still a scroll pressed on the scroll, and he was so pumped that he didn't have to collapse it!?

But the peddler still had to stop Sang Qingyu at this time, "Young master, be careful!" ”

Sang Qingyu heard the sound, and subconsciously raised his head, he was directly hit by the two scrolls in the eyes, fell to the ground, and finally was walked by the girl, picked up the scroll, and said coldly: "Even if you replace the scroll, it is still expensive, well, a penny." ”

When the peddler heard this, he couldn't help but burst out laughing, and Sang Qingyu was even more embarrassed.

Fortunately, at this time, the owner of the study rushed back, and seeing that the house was in a mess, he hurriedly helped Sang Qingyu up, and scolded the girl a few words, and let the girl go back to the back hall, only to accompany the smiling face and say that Sang Qingyu was injured, and it must be cheaper for Sang Qingyu to buy something.

said so, but the boss calculated it, and it was obviously exactly the same thing that the girl gave to Sang Qingyu, and the boss just calculated dozens of more words.

Sang Qingyu couldn't be injured again and spent more money, so he used the girl's words just now to calculate those things and give them to the study boss.

Just as he had finished speaking, he heard a chuckle from behind the curtain that led from the study to the back hall, as if to say that he had not had to follow her words until the end.

This made Sang Qingyu angry and ashamed, so he refused to say what happened after he came back that day.

Later, when he calmed down a lot, he learned from the hawker that the girl was Qian Fang, the daughter of the owner of the study, who had been smart since she was a child, especially good at calculations, and seemed to have a slight idea about the business.

After the study owner came back from illness, the study business plummeted again, but despite this, the study owner still refused to let his daughter come out to run the study, and finally the study was about to close.

"Wow, there is really a sister who is even better at arithmetic than the second brother." After listening to this, Ning Ning couldn't help but speak up. "Then it should be that sister just listening to what the second brother is talking about in Ning Ning's ear today, it will definitely be better than the second brother!"

"Ning Ning, you ......" This person hasn't been invited yet, won't his status in Ning Ning's heart be good? Sang Qingyu was suddenly a little frustrated.

"Why don't you invite that girl?" Seeing that Sang Qingyu was depressed, Sang Qingyan said tentatively, besides, listening to this tone, the girl's family is afraid that it will be difficult to pass away.

"That won't do! Wouldn't it be the biggest waste of money for that girl to let her stay at home!? ”
