However, joy is joy, but to say satisfaction, Yang Yuanding is still dissatisfied.

He pulled Zhang Sijiu back to his study, and said with a sad face, "I knew this matter was not easy, but I didn't expect it to be so difficult. Do you know what the oil yield of rapeseed is?"

Of course, Zhang Sijiu didn't know this.

So he shook his head blankly.

Yang Yuanding said softly: "It's about 30 to 40 percent, and the sesame seeds are a little higher, and the oil yield can go from more than 40 to 60 percent. Peanuts are also very high. Rapeseed can only be considered ordinary. But now, our oil yield is only more than 20. It's too low."

So low that he felt it was a bit uneconomical.

Zhang Sijiu was completely different from what Yang Yuanding thought about when he was depressed.

She looked at Yang Yuanding and asked him two questions: "Is the technology we use the most perfect? Is the machine state-of-the-art?"

These two questions stopped Yang Yuanding.

Yang Yuanding opened his mouth and shook his head for a long time: "Of course not. I just watched a documentary, and I didn't have any know-how, and I couldn't talk about technology. It can only be said that it was simply and rudely done. As for advanced machines, it is even more unlikely. Modern times are all automated, steel machines. Now we're doing it manually."

"Then why are you so demanding?" Zhang Sijiu asked Yang Yuanding, a little helpless: "Your requirements are too high."

If the most rudimentary technology and machines can be used to achieve a perfect oil yield, what are the modern machines invented? When ornaments?

Yang Yuanding suddenly perked up in an instant: "Yes, yes, Jiuniang, you are right, I think too much. It's too demanding. I've got to give them room to improve! Anyway, the oil is in rapeseed, and the content is so high, whether we can get it out as much as possible depends on our improved technology. No need to worry about it!"

Experiment! He will! Control all kinds of variables, adjust all kinds of links, this can be piled up with time and energy!

It's hard at the beginning, but they're already at the beginning!

And even know where the ultimate goal is! Isn't that easier than doing research?

He made a bold statement full of enthusiasm: "Si Jiu, you wait, in less than half a year, I will definitely be able to achieve at least 30% oil yield!"

Zhang Sijiu didn't hit his self-confidence either, and nodded without hesitation: "Okay! Then I'll wait and see!"

That night, when Zhang Sijiu and Zhang Xiaoshan went home, they went back with a bowl of oil.

According to Yang Yuanding, the rapeseed oil that the Zhang family has grown for half a year should also be tasted as soon as possible. Therefore, the oil squeezed today was divided into two halves by him, half of which was kept for Yang County Commander to see, and half was taken home by Zhang Sijiu and them.

The Xu family actually waited with their eyes blank.

I just looked through the autumn water and stretched my neck, but I didn't see my uncle and nephew come back, one by one, very anxious.

Finally seeing people, Xu couldn't help but greet him: "How is it, how is it? Can it produce oil?"

Others can still have a little bit of a lively mentality, but the Xu family can't, and the entire Zhang family can't do it - these rapeseeds, every one of them is planted by them with hard work! So can you not be in a hurry?

Zhang Xiaoshan held down Xu's and didn't let her ask more, carefully holding the oil bowl in his arms, until he entered the house, he opened his arms, put the oil bowl on the table in the hall reverently and solemnly, and motioned for Xu and Zhou to take a look.

The family, just around this bowl of oil, couldn't take their eyes off it.

Komatsu sniffed vigorously, smelling the special smell of rapeseed oil, looking at the color of rapeseed oil, and asked curiously, "What is this oil called?" Is it green oil?"

This title made Zhang Sijiu couldn't help but laugh - the scientific name of rapeseed oil is rapeseed oil. But in many places among the people, it is indeed called green oil.

She asked Komatsu, "Why is it called green oil?"

"It's dark cyan." Komatsu was proud: "Sesame oil smells fragrant, so it's called sesame oil, this oil doesn't smell good, but it's not good to call it stinky oil." Therefore, if it is green in color, it might as well be called green oil!"

This very apt nomenclature made Zhang Sijiu even more unable to stop laughing: "Okay, good, then it's called Qingyou."

Xu Shile hehe: "It doesn't matter if it's green oil or red oil, as long as you can eat it anyway, it's good oil!"

Zhou is also in this position.

The family hadn't seen enough, and the other people who knew the news of Zhang Xiaoshan's return couldn't wait to come over and ask if they had squeezed out the oil.

As a result, this bowl of oil has become a rare treasure, and everyone who comes over must take a closer look - if the naughty child gets closer, he will be scolded immediately.

Zhang Sijiu felt, where is this a bowl of oil? This is clearly a baby golden pimple!

Moreover, such a bowl of oil, used to collect tickets, it is estimated that some people are willing to come and see it!

This kind of onlookers lasted until the next day.

Li Zheng came to the top door early the next morning.

At that time, the Zhang family was still having breakfast - the next meal was scrambled eggs.

In order to be worthy of this hard-won green oil, Xu generously took out four eggs and scrambled a large plate of eggs.

Zhang Sijiu had just eaten a pair of chopsticks, and Li Zheng came.

Xu Shi heard the movement, looked at it, and suddenly became a little entangled - according to the way of hospitality, entering the door is a guest, and at this time, no matter what, you should greet Li Zheng to take a bite together.

But right!! Xu also ate scrambled eggs with green oil for the first time, and he was reluctant to clip too many chopsticks.

It's not that she feels sorry for the egg.

It's distressing green oil.

After all, I just got a bowl of green oil.

Although there will definitely be one in the future, but that will be later, and who knows how long it will take!

Zhang Sijiu looked at Xu's pained little expression, and was simply dumbfounded: The second aunt would have such a tangled time?! What a miracle!

However, it won't hurt to this point.

Zhang Sijiu was about to persuade, but Xu still put down his chopsticks and glanced at Zhang Sijiu: "You can eat this plate of eggs, I'll fry another plate, Lizheng is here, and it's not easy to hide it."

Although green oil is precious, it can't really be picked like that.

Zhang Sijiu replied with a smile. Then he watched Xu walk out and greeted Li Zheng warmly.

Although Li Zheng was also very polite, the politeness did not last long.

As soon as I heard that it was made of oil squeezed from rapeseed, I rubbed my hands shyly: "Then I'm welcome, taste it."

When he said this, Li Zheng was also a little panicked, and he always felt embarrassed, after all, he was old, and he really hadn't done such a thing.

But if you want to refuse, he is really reluctant! I have long heard that rapeseed is pressed for oil, but whether it can be eaten or not, I have only heard! Now that there's a chance to give it a try, how can you not give it a try!
