Sign in and get rich in farming

Yu Hongdou compared the golden bead to the hole on the inner ring of the octagonal nut, and an idea suddenly appeared in her mind.

She looked around hurriedly, then picked up one of her wooden hairpins.

Carefully pin the wooden hairpin to the notch at the lower right corner of the inner circle, and pin it counterclockwise. However, this method does not apply the right force, and the inner circle does not move at all.

Yu Hongdou tried for a long time, but finally gave up. She looked around again and her eyes fell on the door bolt used to lock the other door.

The door latch is a square piece of wood, and its size seems to be just right for use.

Yu Hongdou didn't care whether the door was locked or not. She just took down the door latch and poked it on the ground. She put the octagonal nut part on it. Hey, it fit perfectly.

The round inner ring of the nut was just stuck on the four corners. Yu Hongdou clamped the bottom of the wooden strip with his feet and held the nut parts with both hands and turned it hard.

Once, twice, soon Yu Hongdou felt the nut parts under his hand loosen.

The little hand that had used brute force soon began to hurt, but Yu Hongdou didn't feel it at all.

She became more and more excited, and her hands moved faster and faster. The octagonal nut on the outer ring was unscrewed silently.

"Ding~" As the nut separated from the inner ring, something actually fell to the ground. Yu Hongdou was startled and looked carefully. She found that what fell to the ground were golden beads.

Looking at the shape, size, color and material, it is exactly the same as the one she placed on the table.

Hehehe, Yu Hongdou grinned silently for a while, picked up the golden beads one by one, looked at them again and again under the light, and then put them together with the one on the table into the cigarette holder.

"1, 2, 3..." There were a total of 4 golden beads that fell to the ground, plus the one she was originally in her hand, a total of 5. Yu Hongdou counted them once, picked up the nut and took a look at it.

As she expected, there was a circle of grooves in the nut's ring, and two gold beads were inlaid in the grooves.

There are 7 in total, no, it should be said that there are 8 gold beads in the nut, and she currently has 7.

Yu Hongdou pressed the golden beads into the grooves one by one, and then gently screwed the inner ring in.

She didn't tighten it so tightly and shook the nut part. She found that the gold bead pressed in did not shake or make any sound. She couldn't help but admire its exquisiteness.

In the past, Yu Hongdou could be said to be half useless when it came to mechanics. It was only after studying with Mo Shougui in recent years that she began to have a clear understanding.

Fortunately, her past education model and information acquisition allowed her to gain a lot of common sense. Combined with the practical knowledge taught by Mo Shougui, Yu Hongdou's understanding and design of machinery has improved rapidly.

She put the nut parts away, guessing in her mind where it would be used, expanded her thinking and drew several fanciful pictures, and did not fall asleep until midnight due to sleepiness.

Yu Hongdou did not sleep well that night. She thought too much before going to bed, which caused her cerebral cortex to be overactive and all kinds of strange dreams came one after another.

It was just daybreak when Yu Hongdou woke up when a rooster from somewhere crowed loudly for the first time.

He stared at the ceiling with a dull look for a long time, then suddenly got up and drew the objects that he vaguely remembered and that had appeared in his dream.

This is a spaceship that looks like a disc on the outside, but is actually an arc-shaped octagon. It is a spaceship that often appears in certain science fiction works.

Perhaps it was because Yu Hongdou had seen it too many times that she subconsciously remembered its appearance.

Relying on the dream revisiting function, she was able to draw it clearly and successfully reminded Yu Hongdou of this timeless science fiction masterpiece.

After finishing drawing the spaceship, Yu Hongdou climbed onto the bed again with a sleepy look on her face. Just as she was about to take a nap, there was a noise in the yard. She suddenly remembered that there was a feast at home today.

The banquet was not held here, but in the old house.

Originally, this trip back was for Yu Songguang to "worship their ancestors" to bring honor to the family, but the Yu family had very shallow roots and there was only one living grandfather in the family, so before returning, they decided to host a banquet at the old house.

As the family involved, except Yu Sanlang who had to come home late or even not come home at all due to official business, Xu, Yu Song and Yu Hongdou had to go to the old house first to entertain the guests.

Yu Hongdou yawned tiredly and washed her face with cold water before she came to her senses.

The family of three had a simple breakfast, and without caring about the guests in the house, they called the second room next door and went to the old house together.

The old house was already full of guests. The village chief lived nearby and came to help early in the morning. As soon as Yu Song entered the door, he was called over.

Yu Erlang brought his son to help watch over the arrangement of tables and chairs in the yard, and he also personally went to entertain several elderly people with disabilities.

The women gathered in the room, picking and washing vegetables, chatting and congratulating each other, etc.

These have nothing to do with Yu Hongdou, a girl who is neither big nor small. However, her task is not easy as she is responsible for taking care of several children.

Yu Hongdou looked at the little kids and her head felt buzzing. She hated taking care of children the most!

Fortunately, the children in the family were well-educated and sensible by Grandpa Yu, especially the eldest cousin and his eldest son who turned into a green tea spirit in the original book.

Yu Hongdou couldn't remember what the little green tea spirit boy was called in the original novel. Now the child named Yu Zhi was just like his name, an upright and brave little man.

He held the small bowl with his tender hands and fed his younger brother rice porridge. During the process, he even wiped his younger brother's mouth and checked whether he had swallowed it clean before feeding him the next mouthful. Yu Hongdou's heart was melted by this adorable sight.

Although he was born to Liu, Yu Hongdou really couldn't hate such a well-behaved child at all.

Even if the child knew in the future that his mother divorced and ran away because of the third wife, and would hate the third wife in the future, at this moment Yu Hongdou just wanted to reward this sensible little boy.

"Xiaozhi, come here~" Yu Hongdou waved at Yu Zhi.

"Third aunt, what are you doing?" After feeding his younger brother, Yu Zhi hugged him and patted him twice. After his younger brother finished burping, he heard his third aunt calling him.

"Here, I bought you some candy." Yu Hongdou took out ten copper coins from her purse and stuffed them into Yu Zhi's little hand.

There are small shops in the village that sell goods regularly, and peddlers come to sell goods every few days, so buying things is quite convenient.

"Thank you, Third Aunt~" Little Yu Zhi already knew money. He looked at the yellow copper coins in his hand and thanked with a smile on his face.

"Third aunt, can I give this money to mom? Mom said she wanted to save money to buy cotton for me, my sister, and my brother to make new cotton-padded clothes for the New Year, but mom's cotton-padded clothes are not warm enough anymore~" Yu Zhi laughed for a while, put the money carefully into the pocket on the inside of his lapel, and looked up to ask Yu Hongdou.

"Well, of course you can, but your mother doesn't have to buy you clothes. Third Aunt will give them to you and your sister later." Who can tolerate such a human cub? Yu Hongdou responded with a smile and asked Qian Sanmei to remember this.

In fact, when they came back this time, Yu Sanlang and Xu prepared a lot of cloth and ready-made clothes, but they were all for the old couple. They also gave two pieces of cloth to Yu Zhen's family, but it was just a favor, a "reward" given to them because they lived with the old man and took care of the old couple.

Cotton is still hard to come by now, especially good cotton for making winter clothes. Most of it has to be purchased from other places, and the price is not low. I guess He is thrifty and loves her children, so she plans to make new cotton clothes for them in bulk.

Yu Hongdou's generosity and promise successfully won the favor of Yu Zhi. His eyes were bright, and he looked at the third aunt whom he met for the first time with joy and excitement. He slowly approached her, covered his mouth with his hand, and whispered: "Third aunt, you are good to us, I want to tell you the biggest secret."
