Wen Yao's surprise startled both Luo and Wen Laohan.

"What's wrong with that?" Old Man Wen asked tremblingly, for fear that Wen Yao had forgotten something important or was about to toss something out again.

This pile of things made Wen Yao forget about the oil extraction.

"Before, you said that every household can grow beans, but in our village, except for those fields where sweet potatoes and potatoes are planted, all other fields can grow beans, what if so many beans are not used up?" Wen Lao Han said.

Wen Yao is not worried at all now: "Master, you just put your heart in your stomach, don't say that you can't use it up, I'm still worried that it's not enough, I need a lot of it in my milk workshop, and my milk's current sauce has to be sent to the capital." ”

Speaking of this, Luo's back straightened, and he glanced at the old man with pride.

Old Man Wen snorted twice and was unwilling, there was no way, the old woman was earning much more money than him now, and she didn't dare to be tough.

With the oil press in mind, Wen Yao didn't stay in the old mansion for long, and went back with Datou and Mama Shi.

As soon as she got home, Wen Yao plunged into the study, bought a book about the oil press from the space, and began to study it.

After washing, the big head saw that the light in the study was still on, so he ran over.

Now only he and his sister are left in the house, and although Datou is used to the days when his eldest brother and father are away, he still can't help but miss them many times.

Seeing that Wen Yao was still in the study, he thought about coming over to accompany her.

"Sister." The big head gently pushed the door open, poked out a small head and shouted.

Wen Yao subconsciously wanted to collect the book, and when she saw that it was the big head, she put the book back on the table and beckoned to him.

The big head ran in, and didn't forget to help Wen Yao close the door of the study again.

When I got to the table, I saw Wen Yao reading a book.

It's not strange for Wen Yao's books now, although they are a little different from the books in the academy, but he has been reading this kind of book since he started to read words, so he doesn't think there's anything wrong.

"Sister, what are you looking at?" The big head climbed onto the stool next to Wen Yao, and looked curiously at the page that Wen Yao opened, which happened to talk about the principle of oil extraction by an oil press.

The big head tilted his head: "Oil? Sister, can beans still be squeezed for oil? ”

Wen Yao picked up the book and continued to read, while replying: "Yes, not only soybeans, but also melon seeds and peanuts grown by our family, as well as rapeseed and sesame, you see, isn't it written on it." ”

Wen Yao pointed to the column of materials that can be used to squeeze oil in the book, and these things were written on it.

"Wow." The big head looked surprised, the sisters and brothers just put their heads together, and continued to look at it, Wen Yao finished studying the principle of the oil press, and wanted to draw the drawings.

"Sister, I'll help you ink." The big head volunteered, and although the person was just as tall as the table, he still tried to help.

Wen Yao pinched his little face and took out his charcoal.

"It's not easy to draw with a brush, I use charcoal to draw, you can play by yourself next to it, or take a piece of paper and draw with me." Wen Yao said and began to copy.

Modern oil presses are all mechanically operated, but fortunately, this book records the entire evolution process of the oil press, from the original simple version to the later mechanical version, but Wen Yao hid the pages behind the book, leaving only the original one, otherwise it would take half a day to explain to the big head what is mechanical operation.

Wen Yao lay on the table and copied the drawings, until Mama Shi lit the oil lamp and came over, and saw that the sister and brother were still busy, so she couldn't help but persuade: "Miss, little master, it's not too early, it's time to rest, little master has to go to school tomorrow." ”

Wen Yao saw that it was indeed very late, so she stopped her pen and glared at the big head: "Go to sleep." ”

The big head didn't move his buttocks: "Sister, don't you sleep?" ”

"I'll wait a while, I'll go to bed after painting, you go to bed quickly." Wen Yao said.

The big head was unmoved, but sat on the stool and shook his little feet, and said to Mama Shi, "Mama, I'll wait for my sister together." ”

Mama Shi looked embarrassed and looked at Wen Yao: "Miss, look at this ......"

Wen Yao had no choice but to put down the pen, and knew that she couldn't draw for a while, so she had to compromise.

"Okay, okay, go, go to sleep." Wen Yao put away the things and walked out with his head in tow.

The big head was led by her, jumping up and down, but when he arrived at the door of the room, he didn't go in, but looked at Wen Yao with his head held high and said, "Sister, can I sleep with you today?" ”

The big eyes are blinking, and it's very pitiful.

Only then did Wen Yao realize that his mood was not quite right, and asked, "What's wrong?" ”

The big head lowered his head and whispered, "I miss my father and big brother." ”

Wen Yao also suddenly became sad, not to mention the big head, even she also missed Wen Xiuyi and Wen Jun.

This kind of family separation is really uncomfortable.

Thinking of this, Wen Yao took the big head and skipped his room directly, walked towards his room, and said to Mama Shi: "Mama, you go to rest, I will take the big head to sleep today." ”

"Yes, miss." Mama Shi saluted, gave them the lantern in her hand, and went back to her room.

Lying on the bed while sleeping, with his big head next to Wen Yao, he suddenly spoke: "Sister, will you also leave home in the future?" ”

Wen Yao was stunned for a moment, and turned her head to look at him: "Why did you suddenly ask this?" ”

The big head looked at her, suddenly approached the arm holding Wen Yao, put his head on her shoulder, and whispered: "I like my father and brother very much, and my sister, let's not separate our family, okay." ”

This inexplicable sentence made Wen Yao unclear, just like her, she was separated from anxiety, and she missed her father and brother.

Wen Yao patted and coaxed again and again: "We also like Datou very much, and our family will never be separated." ”

As the sound of breathing around him gradually stabilized, Wen Yao carefully withdrew his hand from Datou's arms, looked at his movements, and saw that he was not awake before carefully climbing out of bed, went outside, lit the oil lamp, and took out the drawings and books to talk about the last point to finish.

The next day, the big head woke up in Wen Yao's bed, and was stunned for a moment before remembering what happened the day before, but there was no shadow of Wen Yao on the bed, and the big head didn't know why, so he quickly put on his clothes and shoes and ran out.

It wasn't until he saw Wen Yao's busy figure in the kitchen that he stopped, and looked at Wen Yao's busy appearance in a daze.

"Little master, you're up, why don't you call a slave." Mama Shi hurriedly came out of the kitchen.

"Hello, Mama." The big head shouted, and ran into the kitchen, just like before, on the edge of the stove, watching Wen Yao prepare breakfast.

The only difference is that he was not even as tall as the stove before, but now he can see the contents of the pot even without stepping on his feet.
