The afternoon sun shone on Li Yiming's face, and the sweat on his face reflected the crystal light.

"For... Belch... Why do you suddenly say this......"

"Because of what you have suffered, I will not let it suffer in vain!" Li Yiming looked at his father and said seriously.

Li Jianguo looked at his son's serious and serious face in a daze, and opened his mouth slightly, but he didn't know what to say.

After a long time......

Li Jianguo tightened his lips, there were tears in his eyes inexplicably, and he reached out and put his arm around his son's shoulder and patted it heavily: "I know!

"Let's go!"

The shade of the trees was high and low, sometimes blocking the view, sometimes suddenly opening up, and the salty sea breeze blew on their bodies, and the two walked silently on the mountain path for a while.

"There are a lot of things, I know that there are no more things than you......" Li Jianguo sighed.

"Dad, I still have a lot to learn. ”

Li Jianguo smiled: "The social contribution you talked about today is the standard for you to do things, right?"

"Actually, that's what I just figured out. ”

"Well, this is actually really good, I thought about it, all these things you do are good for the country. Li Jianguo touched his son's head, "Before, I treated you too much as a child, but in fact, ......"

Li Jianguo pulled out of the emotions just now and smiled self-deprecatingly: "It's hard to explain this to me, isn't it? Your father doesn't have much education, he hasn't gone to college, he hasn't read any books, and he doesn't know much......

"There is no ......" Li Yiming looked at his father, there was no smell on his body, only sweat.

Among those people who were digging dung and picking dung in the mountains and fields, there was a boy who was his father.

"Dad, it's not like going to college to study. ”

"That's what I said, at my age, I can't learn things quickly, so be more patient when you tell me!" Li Jianguo said slowly.

Li Yiming hummed silently.

"I don't know how to really help you......" Li Jianguo sighed softly, "I don't know if the report can be done to the extent you want." ”

"Dad, don't worry about this!" Li Yiming held his father's hand.

"How can you not be worried...... I'm going back, you're here alone, it's so dangerous, if I can't explain the situation in time,......" Li Jianguo shook his head, his heart was heavy, "I know you're not afraid of sacrifice, but ......"

"I know, Dad, don't worry, I've already arranged everything!" Li Yiming said in a low voice, "I won't be alone." ”

"Huh?" Li Jianguo stopped.

"I'll put everybody to good use. Li Yiming squeezed his father's hand to make him really feel at ease.

"Resource theory?"

"Well, yes, resource theory. ”

"If only we could understand that...... Now that I'm older, I don't know if I can catch up with ...... when I re-study" Li Jianguo sighed worriedly.

Li Yiming lowered his head and gently kicked a stone, the people of his father's generation now have to work and take care of their children, almost from morning to night, the lack of education, and the incomplete knowledge structure will soon make them fall behind the times.

They have worked hard for so many years, but they have not been able to build the motherland well, and Li Yiming can understand that feeling from those words.

But what these people don't know is what kind of terrible changes they will encounter in the future, but their generation, especially those who have really endured hardships, become educated youths, and have served as soldiers, have another very valuable trait, that is, they have real perseverance.

"Dad...... You'll learn, it's not too late!" Li Yiming comforted.

"Well, I... We'll learn well. Li Jianguo tightened his son's hand, "Speaking of which, my father is a little awkward, and I want you to arrange it......"

Saying that, Li Jianguo was also a little helpless.

Li Yiming suddenly frowned: "That's right, Dad...... Digging up manure and picking up manure ...... Did it all be men at the time?"

"yes, what's wrong?" asked Li Jianguo.

"No, there's a contradiction in one thing. Li Yiming shook his head, he often looks at an era through those, if those authors don't know the current era, but what they know best is actually the world thirty years later.

Thirty years later, it is completely a world that hates the poor and loves the rich and looks at faces.

When my father talked about digging up excrement just now, he quickly searched for information about excrement digging in his head, 163 of which were 120 of them "dung boys......

At first he thought it was a tragic story of left-behind children who couldn't make a living and went to dig dung, but then he soon found out that it was a popular idol group!

But why is there a popular idol group called the dung digging boys? Is the name inspirational or ugly?

If it is said to be inspirational, this is completely inconsistent with Li Yiming's understanding of the social situation after 30 years!

If you talk about judging ugliness, it seems that this combination is quite popular.

"What is it?" asked Li Jianguo with concern.

"It's nothing, it's just that thirty years later, there will be an idol group called the dung digging boy,......" Li Yiming muttered.

"Huh?" Li Jianguo's eyes widened.

"They were very popular. ”

"It's... Is it?" Li Jianguo looked puzzled and relieved.

"I'm afraid it's not really excrement. Li Yiming shook his head.

"Uh...... Will there still be this job in 30 years?"

"I don't know...... It's better not to be so backward, so you should use biogas. Li Yiming looked at his father, "I saw in the information that there are several machinery factories, and I asked them to make some prototypes, and you can bring them back, it should be possible to produce them in the mainland." ”

"For manure?"

"No, I'm thinking of a whole solution," Li Yiming lowered his head and said as he walked, "I know what kind of vat you are talking about, it is really inconvenient, and the smell is mainly the smell of ammonia and hydrogen sulfide in the biogas, um.... Wait a minute, Dad, you said you were mixing plant ash with dung to make manure?"

"Well, what's wrong?" Li Jianguo was directly stunned by his son's question, and this tone was that he had found a problem.

"Manure is acidic fertilizer, and plant ash is alkaline fertilizer!" Li Yiming raised his head and looked at his father, "Did the agricultural technology station say that there is anything special about using this?"

Li Jianguo was stunned and shook his head: "No, there were technicians at the time, but we all did this...... Uh, questions?"

"Well, fertilization is still particular, and crops have different nutrient requirements for different growth periods,...... Sometimes several fertilizers are put together, but the fertilizer effect is gone, and the plant ash is ...... Is it burning straw? Is it straw?"

"It's not about burning straw, it's about using straw to weave mats, at that time, we used fire directly to open up the wasteland, and the ground was full of ashes, so we mixed them with those, do you mean it's not nutritious?" asked Li Jianguo in surprise.
