A young boy from the 1970s, separated from his family, fled famine and led his younger brother into

"How can we ensure that everyone in Harbin can enjoy fresh vegetables during the winter?"

Looking at her daughter's meticulously drawn "plan," which even highlighted key points with different colored watercolors, and listening to this earth-shattering "bold statement," Zhou Yayun felt as if she were not talking to a five-year-old daughter, but listening to a report from a leader of the Ministry of Agriculture of a certain country.

This...this is just too far-fetched!

"Nianci," she said carefully, afraid of discouraging her daughter's enthusiasm, "I know you're smart, and I know you want to help with the family. But, growing vegetables in winter... it's not practical."

"Since ancient times, in this freezing weather, let alone vegetables, even the ground is frozen as hard as stone. How could anything possibly grow here? This goes against the laws of nature!"

"Mom, who said it has to be planted in the ground?" Lu Nianci smiled mysteriously.

She turned to the second page of the plan, which contained an incredibly detailed design.

It was a strange, semi-circular structure with a wooden or bamboo frame and covered by a transparent membrane.

"What is this?" Zhou Yayun and Lu Zhenguo both leaned over at the same time, looking curiously at the design drawing they had never seen before.

"I call it 'greenhouse'."

Lu Nianci pointed to the blueprints with her little finger, like a professional architect, and began to explain them to her two "clients".

"Simply put, it's like building a transparent house for the vegetables."

"The walls of this house should be made of a translucent material, such as plastic film or glass."

"This way, sunlight can shine through this 'wall' during the day."

She picked up a pencil and drew a small sun and several rays representing sunlight on the drawing paper.

"We all know that sunlight has heat. Once this heat enters the 'greenhouse,' it is difficult for it to dissipate because of this 'wall' that blocks it."

"In this way, the temperature inside the 'greenhouse' will be much higher than outside. Just like when we sit in a car with the windows closed in the summer, it feels extremely hot."

We call this phenomenon the "greenhouse effect".

Greenhouse effect?

This term, which is now known even to elementary school students, was an extremely unfamiliar and technical physics term in the 1970s.

Zhou Yayun was completely confused and looked utterly bewildered.

But Lu Zhenguo was a man of exceptional insight, and his eyes sharpened instantly upon hearing those four words!

He seems to have seen a similar theory in some internal scientific journal!

"With enough warmth, we can move the soil into a 'greenhouse,' water it, and fertilize it. Wouldn't that allow us to grow fresh vegetables in winter?"

Lu Nianci explained the principle of this technology, which was considered "cutting-edge technology" at the time, in the simplest and most straightforward language.

Zhou Yayun remained skeptical.

But Lu Zhenguo's heart was in turmoil!

He stared intently at his daughter's innocent yet intelligent face, then glanced at the design drawing filled with various data and symbols, its logic impossibly rigorous.

He felt that his understanding was being shattered little by little by his five-year-old daughter.

Is this...is this really something a five-year-old could come up with?!

This kind of knowledge, this kind of logic, this kind of foresight...

Even professors at agricultural universities are probably no better than this!

"Who...who taught you all this?" he asked with difficulty, his voice hoarse from shock.

coming.

This is the same question again.

Lu Nianci was already prepared.

She raised her head, her face showing an expression of immense pride and self-satisfaction.

"It's my dad!"

She brought out this universal and irrefutable reason once again.

"My dad has so many books! Some are about war, some about farming, and there are lots of pictures I can't understand!"

He said, "We, the descendants of soldiers, must not only know how to defend our country, but also how to build it!"

"I saw all of these in picture books!"

She attributed all the "irrationality" to her father, Su Weiguo, who had already sacrificed himself but was portrayed as a "god of war" in everyone's hearts.

Sure enough, when Lu Zhenguo heard the name "Su Weiguo," his suspicious and scrutinizing gaze softened instantly.

His eyes were slightly red, and his face showed a complex expression of sadness and relief.

Yes.

Wei Guo, that guy, is such a wildly imaginative and unconventional genius!

Only he could raise such a "monstrous" daughter!

"Good! Good!" Lu Zhenguo slapped his thigh hard, his shocked face now showing an unprecedented excitement and...decisiveness!

"Truly worthy of being the daughter of Wei! She has the same bearing as him back then!"

He stood up and paced back and forth in the living room.

His brain was working at lightning speed.

He was thinking about more than just the "trivial matter" of whether he could eat vegetables in winter.

He was thinking about things much deeper and farther away!

if!

If this "greenhouse" can really be a success!

What does that mean?

That means that the soldiers on their northern border who guard the country's gates in the freezing cold, eating frozen potatoes and compressed biscuits, will have the opportunity to have a hot bowl of vegetable soup in winter!

That means that their entire Northern Military Region, and even the entire northern part of China, will finally solve the historical problem of winter vegetable shortages that has plagued them for thousands of years!

This...this is such a tremendous achievement!

This is of immense strategic importance!

Thinking of this, Lu Zhenguo's heart, which had been dormant for many years, began to beat wildly again!

He felt as if he had seen a tremendous opportunity that could change history!

The key to unlocking this opportunity lies in the hands of his five-year-old daughter!

"Dad?" Lu Nianci looked at her father's unpredictable and agitated face and called out tentatively.

"Dry!"

Lu Zhenguo suddenly stopped, turned around, and stared intently at Lu Nianci with his sharp eyes. He gave the order in an unquestionable tone.

"Let's do this 'greenhouse'!"

"Not only do it! We'll do it big! We'll do it extra big!"

He pointed to the vegetable patch in the backyard outside the window, which had been abandoned because of winter, and said with great pride, "This whole plot of land is yours!"

"Tell Dad what you need! Money if you want, people if you want!"

"I'm giving you a week! I want to see that 'greenhouse' you mentioned in our backyard!"

With her father's full support, Lu Nianci was overjoyed!

She knew that as long as this matter was elevated to a "strategic level," her father, a soldier with extremely high ideological awareness, would absolutely not refuse!

"Thank you, Dad!" she said sweetly, giving a not-so-standard military salute.

However, after the initial joy, a harsh reality hit them like a bucket of cold water.

Money if you need money, manpower if you need manpower.

That sounds wonderful.

However, in the 1970s, many things could not be solved simply by having money and connections.

For example, the two most crucial materials for building a "greenhouse"—

Large-area, highly transparent plastic film.

And sturdy enough wood or bamboo poles to withstand wind and snow.

In an era of extreme scarcity where everything required ration coupons, these things, especially the former, were even rarer than gold!

Where is she going to get these things?

For the first time, Lu Nianci's brows furrowed deeply.

She realized that her "genius plan" had encountered an almost insurmountable chasm in the very first step of its implementation.
