The old Qin Tou, who was the leader, glanced at Lu Ting and said respectfully: "Lu Gongzi can take advantage of it, if he is not satisfied, the little old man can change it at any time." ”

The eyes were full of resentment, Lu Ting's goosebumps rose, and he said yes, put this luxury version of the abacus on the stone table, and prepared to test.

If it is a beautiful girl, looking at herself with resentful eyes, it may be a good thing, but Lao Qin Tou is an old man over fifty years old, that old face has a fight with the second uncle, and he can see that he is crazy in his heart, judging from the performance of Lao Qin Tou just now, he is a perfect seeker with obsessive-compulsive disorder, and he refuses to have silver horns and carved cloud patterns, and the old man always feels imperfect and unhappy, so he complains about himself.

As for it.

Lu Ting shook his head, put aside the distracting thoughts in his mind, and casually played the abacus, the abacus beads carved from red sandalwood felt mellow to the touch, and the fight was crisp, and the time when the beads collided, there was a certain magical rhythm in the tightness, as if he was playing music, and Zheng Yanzhi's eyes on the side lit up.

I thought that the finished product would be good, but I didn't expect it to be better than I imagined, especially the crisp sound of dialing the beads, which seemed to be as wonderful as the sound of music in Zheng Yanzhi's ears.

Lu Ting silently wrote out the addition and subtraction mantra from memory, and said with some regret: "In fact, there are rules to follow, but unfortunately I haven't thought of it for a while, but Miss Xiaozhi's attainments in clear calculations are not difficult to figure out." ”

I haven't touched it for a long time.,In the previous life, I met when I was reading.,As soon as the electronic calculator comes out.,The abacus is not fragrant.,But when I read, I often compete with the same table to plan the speed of the plate.,At that time, it was addition and subtraction.,Multiplication and division didn't use.,I only remember the mantra of addition and subtraction.。

Zheng Yanzhi said convincingly: "Lu Gongzi is talented, even if there are two formulas, it is really not easy, the slave family must work hard to perfect the formula, and forgot to ask Gongzi, what is the name of this thing?" ”

I don't believe that Lu Ting can come up with this auxiliary tool in such a short time, let alone summarize the formula in a short period of time, no matter what, even if Lu Ting pondered this matter as soon as he was born, that is, for more than ten years, many Ming Arithmetic professors have not summed up a single mantra in their lives.

As for Lu Ting being so young, but his attainments in Ming Arithmetic are so high, Zheng Yanzhi has no doubts, some people are born with God's love, like a one-year-old literacy, three-year-old memorization of scriptures, and it is not uncommon for a prodigy who can compose poetry at the age of seven, Gan Luo is a twelve-year-old prime minister, Cai Wenji is six years old to debate strings, Cao Chong can judge cases at the age of five, Lu Ting has become a Ding, and it is not a demon to have talent in Ming Arithmetic.

"I don't have a name yet, this thing has been given to Miss Xiaozhi, if Miss Xiaozhi likes it, it's okay to call it Xiaozhi Pan."

Looking at the way the little girl's eyes lit up, she knew that she attached importance to the abacus, anyway, it was a favor, so it was better to be generous.

"Slave Xie Gongzi." Zheng Yanzhi was overjoyed in her heart, and once again saluted Lu Ting, and said with a straight face: "If his son needs help, the slave family will do his best." ”

The finished product is there, the formula is also there, Ayajin's gift to the King of Qin is complete, with this dedication, Aya's status will definitely be greatly improved, and the ancestors will praise their ability, as long as they make Ayah happy, they are also a lot more free in terms of family affairs, and they accept such a big gift, only six hundred times is too little, and they still owe Lu Ting a favor.

Zheng Yanzhi doesn't like to take advantage of others, and she doesn't want to take advantage of Lu Ting, now it's a promise to help Lu Ting again if necessary, but she didn't say everything, she only said her best.

Who knows what Lu Ting will do by himself.

"This matter is over, Miss Xiaozhi will see when it is convenient, send someone to verify the practice of the golden jade bag, verify it earlier, and end this matter as soon as possible." After working hard for so long, it's time to get what you deserve, Lu Ting reminded without a trace.

Six hundred guan, it's really a lot, when I came to Datang, when I was the widest, I didn't even have six guan.

If it were usual, Zheng Yanzhi would definitely embarrass Lu Ting, but Lu Ting is so generous, he can't be stingy, he nodded and said: "I'm sorry that I have been wrong for so long, the slave family has prepared a carriage outside the door to send Gongzi back, six hundred yuan in cash is already in the carriage, Gongzi can count it at any time, as for the secret recipe, Gongzi can hand it over to the next person who is driving the car, it is not early today, and tomorrow I will send someone to learn the production of gold and jade bags from Gongzi." ”

Six hundred yuan is a huge amount of money for the current Lu Ting, and it is just pocket money for Zheng Yanzhi, and she doesn't take it to heart at all, with this calculation artifact in her hand, what if the secret recipe is fake, how can she make a lot of money by herself.

Refreshing, Lu Ting hurriedly thanked him, and when he left, he took out the golden jade bun at the bottom of the food box and gave it to Xiao Qiaowen, so that she could put it in the pot and steam it to eat.

This time I brought a plate, a plate for the little girl to eat, it was considered to buy her, and the rest of the plate was reserved for Lin Zheng's, and the transfer of the secret recipe was ready to talk to her, but I didn't expect Lin Zheng's to go to Suzhou, and it was cheap.

Seeing Lu Ting coming out of Tingyuxuan under the leadership of Guizhi, Zheng Yanzhi hesitated, and suddenly plucked up the courage to say: "Young Master Lu, the slave family has been practicing hard recently, and there has been some progress, the next time we meet, the slave family will definitely play a song for the son." ”

When Lu Ting explained the pheasant rabbit in the same cage, there was a method called the method, why Zheng Yanzhi named the method at that time, and the explanation was that the was good, and the life of a woman who could blow the flute would be much more exciting.

? Play a song for my son?

Lu Ting almost stumbled when he heard this, and thought that he had taught the bad little girl, so he said yes, and then slipped away a little embarrassed.

"Miss, are you okay?" Hongling asked a little strangely as she looked at Zheng Yanzhi, who was lost.

Everyone left, and suddenly said that they wanted to give a to others, you are the eldest lady of the Zheng family in Xingyang, reserved, Hongling wants to cover her face with her hands.

Zheng Yanzhi said a little melancholy: "It's nothing, I suddenly thought of leaving here, I was a little reluctant, although this Lu Ting is a little annoying, he can be regarded as a mentor and friend, this time I say goodbye, I'm afraid it will be indefinite." ”

If there is no accident, I will wait at home for the elders to pick the husband who they think is the right person, and then go out again to sit in a carriage, but a sedan chair, waiting for their own is the husband and son in the courtyard of the deep house, and he will die of old age.

After a pause, Zheng Yanzhi felt that the eyes of the personal maid were a little gossipy, and said with some disguise: "That prodigal son, isn't it a joke that Miss Ben only loves to calculate, and she doesn't even have a musical instrument that she can handle, and she specially learned to blow the flute, so I want him to see, with Miss Ben's qualifications, everything she learns is easy to capture, but it's a pity..."

Hongling was a little surprised and said, "Go? Miss, did you say last night that it was difficult to come out once, and you had to play enough books and stay in Suzhou for another half a month before leaving? ”

"Last night was last night, today is today" Zheng Yanzhi gently stroked the abacus, and said with a serious face: "Aya is in Chang'an, the situation is a little bad, I want to hand over this thing to Aya to dedicate and earn a contribution, so that we can also visit Chang'an again." ”

Speaking of Chang'an, Zheng Yanzhi's face had a smile on her face, the last time she went to Chang'an was five years ago, Zheng Yanzhi never forgot the first time she saw the magnificent Changmen City Gate, the tall city wall, the spectacular gatehouse, the flow of people one after another, and the prosperous two cities, at that moment, I felt that I was in the sky and clouds.

"Miss, we're going... Changan? Hongling was excited when she heard this, and asked with her eyes shining.

Chang'an, that's where the emperor lives, Chang'an City is prosperous and fun, you can see Hu people dressed in fancy clothes, eat food from all over the world, maybe you can also get a little bit of the emperor's luxury, Jane is so good.

"Go to Chang'an" Zheng Yanzhi instructed: "Hongling, you pack your luggage and set off early tomorrow morning, by the way, tell the housekeeper that I want the three carpenters, and let him find out the deed of sale, where is my aunt I will explain." ”

"Got it, Miss" Hongling hesitated for a moment, and whispered: "Miss, leave early tomorrow morning, what about the secret recipe of the golden jade bag?" Don't want it? ”

I spent 600 yuan to buy the secret recipe, and I also gave Lu Gongzi an extra gift, so I left?

Zheng Yanzhi had already thought about it, and quickly said: "The secret recipe has been handed over to me just now, this gold and jade bag was originally bought and given to my aunt, after all, we have been bothering for so long, let Hong'er stay, go to study with the Lin family's cook, and return to Xingyang after learning, when you want to eat, ask her to make it." ”

"Yes, miss."
