Cai Yong came to the account room and did not care about what Xiaolan'er said at all. He happily called out: "Zijin."

"So it's Mr. Cai." Qin Feng stood up quickly and saw Xiao Lan'er following him, so he secretly squeezed his eyes.

Xiaolan'er's face turned red and she said angrily: "Master, this Qin Feng is lazy."

Cai Yong came to ask for the arithmetic formula, and he felt embarrassed when he heard this. If it were ordinary girls, they would have scolded him long ago. However, Xiao Lan'er grew up with Cai Yan, like half a daughter. He had to say, "Lan'er, do you think Mr. Qin is lazy and has evidence?"

Xiaolan'er hurriedly walked over and opened a recent account and said, "Why don't you? Master, look, the accounts for the past few days have not been archived. It's not just laziness." She has been suffering from Qin Feng's secret loss. This time she saw that he had the chance to suffer, so she gloated at Qin Feng.

"Oh!" Cai Yong saw that he did not complete the archive, and it would be more troublesome to accumulate so much.

Qin Feng smiled slightly and took the account. There was a record on the home page. He bought 100 dou of rice in his mansion on the 20th day, and spent 21 dou the day before yesterday, and spent 18 dou yesterday... This was really simple for him. He picked up the pen, wrote 100 on it, 21 on it, and wrote 18 below, "Well, borrow 10, yes, there are 61 dou left in the inventory." Before and after, Qin Feng calculated the results.

Other accounts are similar. They cannot be replaced by items, and they become vegetables, wine, etc. In less than half a stick of incense, the existing inventory accounts of dozens of materials can be calculated clearly. In Qin Feng's opinion, if it is a business transaction account, it may be a bit difficult, but the account of living at home is really not difficult.

Cai Yong and Xiao Lan'er were stunned.

"Manager Qin is indeed a great talent in arithmetic. It's been the first time I saw the master so surprised by something." The servant next to him whispered to his companion.

"Ahem, Xiaolan'er, you can go back. And you guys, let's go down first." Cai Yong said.

Qin Feng squeezed his eyes at Xiao Lan'er, and the latter stomped his feet and walked out angrily.

"Mr. Qin, I watched your vertical multiplication and division overnight yesterday. I only studied the multiplication and division of individual digits. It is still vague about ten digits and hundreds of digits. I want to ask for advice..." Cai Yong said when he saw that there were no outsiders in the house. He did not expect that he was old and had one day to ask young people for advice. His old face turned slightly red.

Qin Feng thought Cai Yong was really Xiao Lan'er called to Chagang, so he came to ask this. The ancients were really ancient and were unwitting. He took out a piece of paper and taught Cai Yong in detail the calculation format of addition, subtraction, multiplication and division. "Do you remember? Even thousands or even ten thousand digits are the same. Practice makes perfect. You can practice more after you go back."

"Yes, old..." Cai Yong immediately blushed and hurriedly left with the paper. Today is really embarrassing. I think I, Cai Yong, are a master, and I am a senior everywhere I go. I didn't expect that I almost shouted out the word "teacher". It's embarrassing. It's still awesome to see Qin Feng in the future.

When Qin Feng saw that Cai Yong and other great writers came to ask for advice, he was extremely proud. His confidence increased, so he thought that he would work hard and resign.

...

"Die Qin Feng, smell Qin Feng." At this time, Xiaolan'er returned to the lady's boudoir angrily.

Cai Yan was adjusting the piano in the room. When she saw her walking in, she said, "Lan'er, who made you angry?"

It’s not just for you, Miss, that I was humiliated by Qin Feng once again. Oh no, twice. Xiao Lan'er blushed instantly, and felt a little numb and itchy on her chest, and said, “I’m going to see Qin Zijin….”

Seeing that she was really going to find Qin Feng, Cai Yan knew the result, and hurriedly put down the strings in her hand and said, "Oh, what happened later..."

"I won't tell you!"

"You damn girl."

"Okay, don't scratch, I'll tell me. Mr. Qin Zijin, it's amazing. He just listed a few numbers like this. In less than half a stick of incense, he calculated the accounts for more than ten days clearly..." I didn't know what Xiao Lan'er was thinking, so he started to say good things for Qin Feng.

"Mr. Qin is indeed an extraordinary talent..." Cai Wenji recalled the song he played when she first met Qin Feng, and became even more curious about him.

Two more days passed in a blink of an eye. Qin Feng was really bored this day, thinking about Cai Yan, so he slipped into the depths of the inner house again. The pleasant sound of the guqin came, and when he turned around a flower bush, he saw that Cai Yan was practicing the guitar in the pavilion again.

As the saying goes, if you want to catch a girl, you must be thick-skinned. Qin Feng walked out and bowed: "I took the liberty to bother you."

"Hey, it turns out that Mr. Qin is here." Cai Yan hurriedly stood up and greeted.

"Hmph!" Xiao Lan'er turned her head aside when she saw him coming.

"Hello, Miss Wenji." Qin Feng walked in and said politely.

"Mr. Qin's song "Xiaoxiang Water Cloud" is melodious, I wonder if it can be taught to Cai Yan." Cai Wenji said shyly, and blushed after saying that. She didn't know if Qin Feng would teach her such a unique music score.

"I can't ask for anything. The lady is born with beauty. Being able to play it from the lady's fingertips is also the glory of this song." Qin Feng really couldn't ask for something. In the future, he could come to Cai Wenji with justification. Good teachers and friends, and maybe he can develop in depth.

"Mr. Qin." Cai Wenji bowed. Xiaolan'er, who was beside her, saw that the young lady was polite to Qin Feng again, and her mouth was so high.

"Miss is so polite." Qin Feng walked over and sat in his seat for a rare opportunity. In fact, he didn't know how to teach, so he had to bite the bullet and play it on the spot, saying one syllable and one syllable to Cai Yan. Unexpectedly, Cai Yan was smart and understood the meaning once and could play it simply after two times.

Qin Feng was able to teach him easily, so he explained the more effective set of techniques summarized by later generations, and the tone would be more accurate. In fact, he could not even play very well, but in theory, Qin Feng was more than a thousand years ahead.

As a master of guqin in the future, Cai Yan's skills have reached its peak at this time. She used her previous techniques to correspond to Qin Feng's adjusted techniques, and felt that the previous techniques were not satisfactory in the performance of the music and could not be compared with Qin Feng's adjusted techniques.

Mr. Qin is indeed very aware of such a mysterious technique. What kind of person is this?

Teaching and learning each other complement each other. This technique cannot be learned in a short while. Qin Feng teaches Cai Yan's modern piano skills every day. Every time he meets, he is gentle, polite and polite, and he knows each other well.

After they became familiar with each other, while playing the piano, Qin Feng would play some strange stories about later generations for Cai Yan. Every time they made her laugh and Xiao Lan'er laugh, Xiao Lan'er gradually no longer became hostile to Qin Feng. He focused on the idea of ​​being a matchmaker and deliberately or unintentionally matched the two of them.

Qin Feng has more than a thousand years of knowledge and has brought out fresh things every day. Cai Yan was interesting to hear, so he woke up every day and looked forward to him appearing quickly. Gradually, in her eyes, Qin Feng became a strange man who knew astronomy and geography, was good at piano skills and arithmetics, and was also good at seal characters. (Hard pen calligraphy, hehe.)

I don’t know when, but the shadow of Qin Feng in Cai Yan’s heart gradually became taller.

On this day, Qin Feng and Cai Yan played the piano and chatted.

"Miss, you are still here. The literary meeting in the front garden is about to begin." Xiao Lan'er said after coming in.

"Sir, then go quickly. My father rarely holds a literary meeting, and many famous scholars will come. This is a rare opportunity." Cai Wenji said tactfully. She knew that Qin Feng was talented, so she thought about him and should not miss this opportunity.
Chapter completed!
