It is said that Zhang Qiang finally returned to normal on the fifth day, and in these five days, he was always stupid and happy, and he was made fun of by everyone. But he didn't care at all, his mother was looking for his fault almost every day, either asking him for things or asking him to divorce his wife. He was so anxious that he walked around for fear of meeting his wife. But now it's okay, his daughter-in-law can still give birth, which gives him the confidence, and he can be laughed at by others?

"Ling'er, will you go up the mountain tomorrow?" Zhang Qiang led people to build a simple grass shed in the backyard of Ling'er's house, which almost occupied half of the backyard, if it weren't for the fact that there were still some cabbage and radishes in the backyard, it would have been all occupied.

"Uncle Zhang, you don't have to go tomorrow, let's start the experiment." As soon as Ling'er's voice fell, everyone was very excited, always saying that this grass was good, but they didn't know how to do it.

After Zhang Qiang and his wife left, Min'er boiled a large pot of hot water, and the two young ladies took a hot bath together. This bath bucket was dictated by Ling'er and made by Bai Liang, Zhou's minister, and after it was made, it became popular throughout Hongsongtun, and Bai Liang also got a lot of things and money because of this. For this Bai Liang couple also specially brought some home-made pickles or something, and thanks to Ling'er, Hongsongtun is not a poor village, but it is only barely fed, so most of the people bring this home-made pickle sauce or something when they walk around.

"Sister, what are you doing here?" After taking a bath, I saw Min'er holding several bowls of soybeans, mung beans and red beans, so she asked curiously.

"Count, I'll calculate Uncle Zhang's salary tomorrow, I have to calculate it today and then prepare to come out." Min'er said as she began to prepare.

"Use this?" Ling'er was very surprised, and then thought that people in this era don't know how to multiply formulas or anything, it's all stupid.

"That's right, this soybean is a tael of silver, this mung bean is a penny, and this red bean is a penny. How can you count it if it's all brains? Min'er also knew that this method was a bit stupid, but she couldn't understand it if she was asked to use her brain to calculate it.

"Sister, you can't do this, do you want to be our grass product experiment, how many numbers do you have to count? This method is okay if it is a minority, but if it is too much, it will not be successful. Ling'er only remembered this practical problem now, and she knew that she would buy an abacus for her sister in the town.

"I know, too, but what about it?" Min'er also has a headache, it would be great if her sister could come up with a good way.

"I have a way, but I don't know if it will work out, why don't we try it?" Ling'er couldn't say that she would calculate, so she could only say that she would try, and the two would work together.

Min'er burned a few small wooden sticks into charcoal according to Ling'er's request, which was very easy, and almost everyone in the entire Xing'an Mansion knew it. Then Ling'er wrapped the burned charcoal stick with strips of rags, and then sharpened the top with a knife, and a few ancient pencils were completed. I tried to write on straw paper, which was far worse than a modern pencil, but it was perfectly usable. Min'er looked at the novelty, and also took one and stroked it a few times like Ling'er.

"Ling'er, is this to be used as a pen?" Min'er is also very smart.

"Yes, it's so convenient, and I can take it with me on weekdays." Ling'er wrote ten numbers from 0 to 9 on a new piece of papyrus. This straw paper is still this time she grinds hard bubbles to beg, you must know that there is no paper to go to the toilet before, of course, the money earned will be used to improve life, or what else to earn?

"Ling'er, what are you doing here? What about wasting paper? Min'er saw Ling'er write one and change it, and her heart twitched, this paper is too expensive. Just about to stop it, I heard Ling'er say:

"Sister, this is the method I came up with, if you learn to count, it will be as easy as eating cabbage." Ling'er saw Min'er's movements, so she quickly took the paper to the kang and was busy explaining. She's not that loser, is she?

"That's what you said, if it's not as good as you say, just wait and see me clean you up." Min'er said with some displeasure that she was very accustomed to Ling'er in eating, drinking, and dressing, but she was quite strict in other aspects. She doesn't want people to say that they are wild goods without mother's education, and if that happens, her sister won't want to marry a good family. I have to say that Min'er has grown up quite quickly, does this prove that you don't grow up in adversity if you don't lie down in adversity?

"Sister, don't worry, it must be better than your method." Ling'er saw that Min'er's face softened, so she took the paper to the kang table, spread each piece of paper on the table, and said to Min'er seriously:

"Sister, these ten numbers were taught by that old man, and it is estimated that no one knows, so we have to keep them secret. In the future, you will use it for bookkeeping or something, and others just don't know what is written, do you think it's okay? "Ling'er doesn't know that there are no so-called Western countries here, so it's better to keep a low profile.

"I think it's okay, if anyone asks, they will say that the two of us made it up." Min'er's current sense of secrecy is no worse than Ling'er's, at first she was just guarding against the Zhao family, and then she realized the importance of secrecy little by little.

"Then let's start learning, this egg-like is zero, it means nothing, it's used to occupy a place, it doesn't matter if you don't understand, just remember it, and I'll tell you about it later." This is one, like a pole ......" Ling'er taught Min'er ten numbers and asked Min'er to recognize and write at the same time. I have to say that Min'er is a clever child, who can completely recognize it in almost an hour, and can write various numbers independently. Ling'er felt very unbelievable, this sister of hers was really talented in numbers.

"Sister, now I'll write some numbers, you can recognize them." Ling'er wanted to test it, and after seeing Min'er nod, she wrote thirty or forty numbers on the back of a used piece of straw paper for her to recognize.

"Sixty-five, three, eighty-seven, nine hundred and forty-three......" Min'er was all right, which made the two sisters very excited. Because Min'er herself has no problem with addition and subtraction, Ling'er began to let her memorize multiplication formulas, which is not so easy. Until Ling'er was too sleepy to fall asleep, Min'er covered her with a quilt, and she was still holding the paper with the mantra written on it and trying to carry it.

The next day, before dawn (5:00), Ling'er was woken up by Min'er, and the sleepy-eyed Ling'er barely opened her eyes and saw Min'er's very excited appearance, and couldn't help wailing:

"Sister, I didn't go to bed until 23:00 yesterday, why are you waking me up now?" Min'er wouldn't have asked her to get up early before, but today is it?

"Ling'er, get up quickly, see what this is?" Min'er memorized the mantra last night when it was almost ugly (1:00), and this morning Yinzheng woke up (4:00), and after getting up, she reviewed the mantra for a while, and then tried to calculate it herself.

"What?" Ling'er is still in a state of blindfolding, Min'er looked at her, went out and got a wet hand cloth and wiped her face, which made her sober up.

"Ah, sister, have you figured it out?" Ling'er saw the paper in her hand, and jumped up happily all of a sudden, genius, definitely a mathematical genius. Thinking about her miserable school experience when she was a child, it was really like a world away.

"Look at what I'm doing, right? I counted it three times and it was the same. Min'er knew very well that she had no problem with it, but she just wanted to confirm it again, probably hoping to be recognized.

"Okay, I'll do the math." Ling'er began to calculate, and it was quickly finished. I saw her frowning and looking at Min'er with a solemn face, and Min'er's heart sank suddenly.

"Sister, I have to say" Ling'er paused for a moment, and then said:

"You're a genius, it's all right, ah...... I was wrong...... I don't dare anymore......" As soon as Min'er heard it, she knew that Ling'er was deliberately teasing her, and she didn't say anything, but she pounced, and then she began to tickle her, and Ling'er was most afraid of this hand.

"See if you dare to tease your sister? You're getting bolder, huh? Min'er was very happy in her heart, and she didn't spend a night. After a while, the two sisters made a mess, and they didn't stop until the sound of Zhao He's door opening came.

Zhang Qiang's family of three came to work at the beginning of the hour, these days Zhang Qiang is mainly responsible for beating the dry Ula grass softly, Aunt Zhang is responsible for using leather to make shoes designed by Ling'er, Min'er is responsible for weaving insoles, and when Aunt Zhang finishes making shoes, the grass wool is put into the shoes and then the insoles and fixes, Er Ya is responsible for hanging the lining into the shoes, and Ling'er is responsible for directing and inspecting the quality.

"Ling'er, I don't have any work here, that grass is enough for you to use for a while, what should I do?" Zhang Qiang said to Ling'er as soon as he entered the door.

"Uncle Zhang, do you know how to weave mats? It's not the thin one we use now, but the thick one. Ling'er didn't know how to express the kind of straw mattress she was talking about.

"How thick? So thick? Zhang Qiang said and compared his fingers to a figure of about five centimeters.

"It's almost that thick." Ling'er used her fingers to compare a ten-centimeter look.

"So thick? I haven't made it up, I haven't seen it. Zhang Qiang said with some embarrassment.

"Then let's try to make it up together, I'll come up with an idea, you make it up, okay?" Ling'er won't either, but she's seen a lot, and I believe that she will be able to make it up after trial and error.

"That's it, I'll go get the grass now." As he spoke, he ran to the backyard.

"Mother, you see how energetic my father is now." Erya was also happy in her heart, but Zhang Qiang was the happiest, and she couldn't wait to walk with the wind.

"It's not because there is hope for the future" Aunt Zhang knew that Zhang Qiang was happy on the one hand because she was pregnant, and on the other hand because there was hope in life. Thinking of this, I couldn't help but look at the two sisters who were working hard, and they both said that good deeds were rewarded, but that's not the case. Their family just stretched out their hand to get such a reward, and she was a little scared. If it weren't for the fact that he would follow the sisters honestly in the future, he would put them first in everything and never betray them, and he would have deserved such a reward. But if they betray them, all these blessings will have to be taken back by heaven, and their families will be punished for generations. In fact, these are all Zhang Qiang's own thoughts, if he doesn't think so, he also feels ashamed. Min'er and Ling'er are so lucky to have met such two couples, if they met that treacherous one, it would be a completely different scene.

"Aunt Zhang?" Min'er was seen by Aunt Zhang.

"Huh? It's okay, it's okay, I'm just thinking about your aunt coming soon, right? Aunt Zhang hurriedly found a topic.

"It's tomorrow, and I guess I can come." Min'er didn't take it to heart either.

"Ling'er, where do I put the grass?" Zhang Qiang hugged a big hug, and when he came in, he found that there was no land in the hall.

"Put it in our house, let's go to that room and think about it slowly." With that, the two of them went in and began to tinker.
