At this moment, there was silence in the conference room.

A pair of shining eyes stared at Qin Ge.

In that trembling gaze, emotions were complicated.

Awe!

Adore!

There is also a complex look of anticipation and apprehension.

Prior to this, they had already learned from their respective channels about the intimidation of the 16-nation coalition forces.

And the person in front of him is the one who moved the world with one word and scared off the coalition warships!

In the eyes of ordinary people, people like Qin Ge are god-like beings.

He is destined to be an indelible legend in the long river of history.

And at this time, the legend stood in front of him.

The excitement made the breathing of these people rapid.

"He is Director Qin, the legend who asserted the rise and fall of the world and warned of the 'Thirteen Natural Disasters'!"

"That's right, it's him! My fathers in the army said that this is a genius who has lived for hundreds of years! How do you look at the age, it doesn't seem to be as old as me! ”

"Nonsense, since he is a hundred-year-old genius, of course he is a crane-haired childish face, which is different from us ordinary people!"

For a while, there was a buzz in the examination room.

Rumors are like rumors, and when they appear in front of the world, their original appearance has long been unrecognizable.

Just like now, in the mouths of everyone, Qin Ge has gradually turned into an immortal old demon for a hundred years.

A group of miraculous remarks reached Qin Ge's ears.

It's just that he didn't explain much about it, but laughed it off.

After a moment, only to hear him cough lightly.

The cacophony came to an abrupt halt.

The huge venue was as dead silent, and the falling needles could be heard.

Qin Ge pointed at the big screen with a laser pointer, and his clear voice spread throughout the venue.

"You are all the sons of my dragon country, and the burden of saving the fortunes of the country is about to fall on your shoulders, I hope you will brave the wind and waves and do not retreat."

After a short opening statement, it quickly moved into the main body.

"Today's exam topic, as you can see: how to carry out three-dimensional agriculture under extreme conditions!"

As soon as the question came out, everyone's eyes flashed with a fine light.

"The limit is absolute darkness, no sunlight."

"The conditions are limited, that is, there are no 10,000 acres of fertile land, and there is not enough time for you to conduct experiments."

"The current agricultural land in Longguo is 10.2 billion mu, or 6.8 billion hectares."

"And the actual operating area I give you is only one thousandth, or even one ten-thousandth."

"You have to raise food rations that can feed a billion people in a very small amount of operational space, in poor or even no soil."

"Note that this is not a theoretical research topic, but a practical operation."

"If you do it right, everyone will be happy. But if you make a mistake, you will starve all over the land of the Dragon Kingdom. ”

"Among the floating corpses on the ground, there are you, and even your parents and sisters!"

Qin Ge's voice was as crisp as cutting gold and jade.

Especially the last word, like a cold blade, cut into the depths of everyone's souls.

Everyone was infected by his piercing eyes and cold words, and they trembled one after another.

As Qin Ge's words landed, the projection on the big screen suddenly changed.

The exam questions disappeared and were replaced by a 3D simulation.

In the ice and snow apocalypse, on the land, the skinny hungry people, the babies waiting to be fed.

What is even more eye-catching is the white bones, which are all over the mountains, like a mountain of bones.

The real picture, which could no longer be real, invaded everyone's mind like an ice edge.

Suddenly, a chill swept over.

At that moment, everyone seemed to have fallen into the Sanjiu Cold Sky in an instant, and the cold hairs on their bodies exploded.

How real that scene was.

Those present were the elite of the agricultural science community, and they knew that this scene of starvation was not fiction.

Because in the long history of the Dragon Kingdom, every few decades, such a terrible tragedy will break out.

This kind of corpse-strewn situation has only disappeared in the past 100 years.

And the picture scroll displayed by Qin Gesuo brought everyone back to that miserable era.

It wasn't until this moment that they finally realized that this meeting was definitely as simple as an exam.

There was a brief silence.

Deathly silence.

After shivering, everyone's eyes became hot.

At this moment, they finally arrived, how heavy the burden on their shoulders was.

What is contained in that burden is the national fortune of the Dragon Kingdom and the life and death of a billion people.

After a long time, someone in the table finally stood up.

It was a slender, thin figure, wearing a pair of glasses that did not match the shape of his face.

"Three-dimensional agriculture, only three-dimensional agriculture can cultivate food rations that meet the needs of one billion people in a limited space."

His voice was deep and clear.

"My idea is to divide three-dimensional agriculture into three parts."

"The first part is to transfer the existing high-quality soil to that barren and limited space for three-dimensional, step-by-step planting."

"In this way, we can effectively use the limited space and carry out three-dimensional planting."

"The second part is soilless culture. With the current technology, the best option is hydroponics. ”

"Large-scale crop cultivation in the form of nutrient solution."

"As long as the temperature and humidity of the cultivation space and the circulation system of nutrient liquid can be effectively controlled, the efficiency of soilless cultivation will be ten or even a hundred times that of soiled cultivation, which can greatly improve the production efficiency of crops."

"The first two methods can be operated in three dimensions to create a symbiotic system, such as a fish-water symbiosis system."

"The nutrient-rich culture liquid is conducive to the growth of a large number of algae, and this liquid is circulated to the aquaculture industry to supply fish and shrimp and other aquatic products. The water quality accumulated by aquatic excretion can feed back to agricultural products, and so on. ”

"And the third part, which is also the most out-of-the-box step, is to carry out satellite cultivation."

"Using existing technology, a number of unmanned satellites will be launched."

"This series of satellites should carry a production warehouse, an artificial LED light source, a temperature, humidity and carbon dioxide concentration control system, and a nutrient circulation system!"

"At the same time, a number of spare dormant chambers are to be launched."

"When the satellite cultivation has achieved initial results, wake up the dormant bin, and dock several satellite bins of the series to form a large circulating bin."

……

Within a full hour and a half, that person spoke eloquently and said the three-dimensional agricultural deployment of the three major parts in an orderly manner.

The congregation was dumbfounded.

Such a detailed and systematic scientific idea will obviously not be a momentary inspiration.

This person's design concept should have been formed for a long time, and has been adjusted and refined many times, so that it can be told so comprehensively.

On the side of the host stage, Yang Qi was stunned when he heard it.

There was an expression of disbelief on his face, as if he was listening to a book from heaven.

"This is also ...... That's whimsical, isn't it? ”

"Such an idea, such a design, it is no longer enough to describe it with four words of brainstorming."

"It's just crazy!"

At that moment, he even had some doubts about the feasibility of the three-step three-dimensional agriculture conceived by this person.

However, when he looked at Qin Ge, he found that there was a hint of relief on his face.

Apparently, he was very happy with the man's crazy ideas.

Facing Yang Qi's questioning, the corners of Qin Ge's mouth raised slightly, and he replied faintly: "This is a crazy era, in order to save the fortunes of the country, we need such crazy talents!" ”
