Yan Yan, who had settled down, began to focus on cotton during this time, because it was already August at this time, and cotton could be picked one after another.

This year, there are still two cotton crops planted in the back garden, and like last year, she specially recorded some matters that need to be paid attention to in the process of cotton growth, the most critical points are, the retention of cotton seeds, the season and temperature of sowing, the time of topping, the time of fertilization, etc.

She needs to get a comparison between this year's production data and last year's production to see which one is better or worse, after all, this is a new thing for her.

Therefore, after picking the first batch of cotton peaches in the back garden, Yan Yan went to the village again and personally took people to teach them how to pick cotton, after all, Zhuangzi is a serious cotton experimental base, there are seven or eight acres of land, Yan Yan handed them over to two planting experts, half of them were planted in the way of Yan Yan, and the other half was

It was planted in the old farmer's own way, but the topping was requested by Yan Yan.

Yan Yan wanted to compare which planting method had a higher yield.

After the first batch of cotton peaches were picked, Yan Yan used the cotton to make a cotton jacket for the queen mother, the emperor and the queen, and she had to study how to weave the rest.

Of course, Yan Yan himself doesn't know how to weave, but most of the old mothers and grandmothers in the family do, because these people are picked from Zhuangzi, and spinning and weaving cloth is as common for them.

It's a pity that the cotton cloth they weaved was too rough to meet Yan Yan's requirements, and because of the limited amount of cotton, Yan Yan was not willing to let them continue to study, after all, for most poor families, the quilt and cotton jacket in winter are the most important, and the clothes are enough to have kudzu hemp.

Who knew that when Yan Yan gave up the study of cotton cloth, Zhou Wan suddenly came to give Yan Yan an August gift, and there was a very special gift in her festival, half a white cotton cloth.

It turned out that Yan Yan divided her cotton seedlings of about two acres of land, and often sent people to guide her to take care of it, and now the first batch of cotton has been picked, and she has nothing to do, she remembered the cotton cloth that Yan Yan was talking about, so she tried to weave the cloth with the first batch of cotton picked, but she didn't expect her to really weave it.

Yan Yan saw that the cotton cloth she sent was much more delicate than that woven by her own family, of course, it couldn't be compared with what Yan Yan wore in the previous life, but it was also very good, at least there was no problem in making underwear.

Under careful questioning, Yan Yan learned that Zhou Wan grew up in Jiangnan since she was a child, and she didn't see much of the weavers at home spinning and weaving, and her family now has two weavers brought from Jiangnan, and the first batch of cloth weaving is also rough, so they have made a little improvement to the spinning machine and loom.

Yan Yan was overjoyed to see that the problem he had been worried about for a long time was solved by Zhou Wan, and Zhou Wan saw that Yan Yan took this half of the cloth and looked at it over and over, touched and touched, and it was obvious that he really liked it, so he smiled and said: "If Sister Yan'er needs it, I will send the weaver girl at home another day." ”

"Don't, let's keep it for yourself, if nothing else, in another three years, the cotton production will be promoted, and the family will be able to live without food and clothing with this weaving craft and the improved version of the spinning machine and loom." Yan Yan waved his hand and smiled.

As for the rest, she can't guarantee it.

"If it is really as my sister said, I am willing to partner with my sister to do this business, without my sister's support, we will never think of improving any machine." Zhou Wan said.

She was like a mirror in her heart, this time she definitely borrowed Yan Yan's light, and the improvement of the spinning machine and loom was not difficult, Yan Yan could probably study it by going to the south to find a few weavers.

Therefore, she proposed to partner with Yan Yan to kill two birds with one stone, not only to repay Yan Yan's favor but also to earn a sum of money to support her family, if the relationship can be maintained, Yan Yan will not be able to take care of her for a few years.

But Yan Yan didn't want to get too close to her, but Yan Yan didn't say anything about it, the variables of three years are too great, especially in this war year.

However, Yan Yan had the heart to ask her how her relationship with the Lu family had been recently, but she was afraid that it would be self-defeating, as if she was guarding against the other party, so she pulled her to ask about this year's harvest.

As he was talking, who knew that Lu You came back in a hurry, followed by an equally excited Li Sui.

It turned out that Li Sui was also interested in these military equipment, and accidentally learned that Lu You gave up his studies in the academy and entered the Ministry of Engineering to study these, and he often went to the Ministry of Engineering to find Lu You, although Li Sui did not fiddle with that kind of large trebuchet and crossbow or something, but he would make cross crossbows, small cross crossbows.

In addition, he is also interested in all kinds of machines, but he usually can't touch these and doesn't read many books, which Lu You just makes up for him, Lu You has not only seen the drawings of these instruments, but he also memorizes the advantages and disadvantages of each device, and he is especially good at reciting words.

Therefore, no matter which master takes out the drawings of that instrument and says the name of this instrument, Lu You can almost find the corresponding text description in his mind, so he is equivalent to a living walking classic.

No, the two have just completed a bow and crossbow improvement that combines a cross crossbow and a crossbow, the diameter of this cross crossbow is about the same as a chopstick, the weight is less than a catty, it can be operated with one hand, and the lethality is quite large, shooting at a pig more than ten zhang away, the pig rolled on the ground a few times, and soon couldn't stand up.

Li Sui was happy, pulled Lu You into the palace to offer treasure to the emperor, the emperor took the cross bow and crossbow in Li Sui's hand and studied it for a while, and ordered someone to go to the imperial dining room to catch a sheep over, Li Cong stood ten feet away from the sheep and shot an arrow at the sheep, but at the same time it was two arrows, and soon the sheep was knocked out of two holes.

The clever Li Cong quickly realized that this kind of crossbow and crossbow can be used to deal with the enemy's cavalry, and when the soldiers meet, the opponent's cavalry occupies an absolute advantage, and the infantry on the side of the Great Zhou is difficult to compete with the opponent, but with this crossbow and crossbow, it is different, the range is long, and it is accurate.

Therefore, knowing that this convenient and small crossbow was thought up by Lu You in combination with the prompts of Mozi and Guiguzi, Li Cong really praised Lu You a few words and rewarded him with a lot of good things.

In fact, this is not the first time Li Cong has rewarded Lu You, when the trebuchet mold came out last time, Li Cong learned that Lu You had a lot of credit, and he also rewarded him with something.

But this time is different, this time it was done by Lu You's own ability, so Lu You is more proud.

And when Li Cong learned from Li Sui that Lu You was not only familiar with all kinds of equipment and books, but also studied the art of war formation, he was also taken aback, but he didn't say anything.
