Faced with this crucial problem facing mankind, all the people attending the meeting were so anxious that they were sweating and didn't know what to do.

This is a problem of eating for 200 million people. Once they starve to death, they will probably be their lifelong inner demon. Everyone knows that this problem must be solved, but no one can come up with a solution to the problem... They would rather fight against Yuan Kou than think of this damn difficult problem.

"I wonder how our human ancestors solved this problem when the great destruction just began?" said a sword holder. Obviously, the sword holder tried to find a solution to the problem from the experience of his ancestors.

"At the beginning, a lot of food was stored in Lao Yanjing City. The ancestor had a natural dimensional pocket, so he brought all of these foods, barely enough for early consumption. When he entered the gap of the rebirth and the environment was a little safer, the ancestor organized the people in the gap to farm, so that he could barely get food that could be eaten by 100,000 people." Liu Nian Lin said actively.

"Yes, we can also farm!" Liunianlin's words made some participants suddenly realize, "We can reopen a large area of ​​fertile fields. Thousands of years ago, when there was no high-tech, our ancestors could plant enough food for hundreds of millions of people with their hands. Now we can also plant it in the most traditional way!"

"That's right!"

"This method is good!" The sword holder's words instantly attracted the approval of many participants.

But soon someone retorted coldly, "I knew it was a guy who didn't understand agriculture at all and could say something. Even the sweet potato with the shortest maturity period would take four months to grow and mature. By then, everyone would have starved to death!"

"Hmph, it's just four months. Our food can last for another month. At worst, everyone can eat less. One bite of food is used as four bites. If you suck it, you can always last for four months!" someone said immediately.

"Yes, after four months, I guess half of the population of 200 million is left. You are the murderer who killed 100 million people!"

"Then what's the solution? It's better than everyone starving to death!"

"Enough, your ideas are really simple. Do you think sweet potatoes alone can support all of us in four months?" The agricultural expert who spoke first couldn't help but say, "If you want to grow sweet potatoes that are enough for 200 million people, it will take at least three provinces of cultivated land to do it. Where can we get so much land for me!"

The moment of this agricultural expert made everyone lose their voice. I didn’t expect that it would take three provinces of arable land to grow enough sweet potatoes.

Even when humans were at their peak, they only controlled eight base cities, and the land area of ​​no more than two provinces was added together. Now the human power has declined to this extent, and the total number of sword holders combined is less than 20,000. In this case, let alone the arable land in three provinces, even 1/3 of one province may not be able to control it.

"Okay, there is no need to argue about this anymore. Agriculture is the foundation of our human race. The planting of fast crops such as sweet potatoes must be prepared now. The people of the Ministry of Agriculture immediately began to collect and control all the crops I have now, and compiled a complete set of textbooks that can allow ordinary people to learn how to plant immediately after reading them... There are no words that are not allowed to be too many, and this textbook must be controlled within 500 words, otherwise no one will understand it if there are too many!" Gu Han said on the rostrum, and the people of the Ministry of Agriculture immediately nodded in agreement. The dispute about agriculture was temporarily put on hold, but it was not resolved.

That is, after a month, all the food is consumed, where should human food be obtained?

"Everyone from the Ministry of Science and Technology, are all the nutrient solution synthesizers damaged? Is there not even one that is intact?" Gu Han asked to the person in charge of the Ministry of Science and Technology.

"Not this. There should be two intact nutrient solution synthesizers in the gaps in the passing years!" The person in charge of the Science and Technology Department said after recalling it.

"Linlin, please take the machine over?" Gu Han turned to Liunian Lin beside him and said. Liunian Lin nodded, and disappeared directly into the venue. After waiting for about half an hour, Liunian Lin brought the two machines back to the venue.

Gu Hanzai looked at the machine carefully and found that the cross-sectional area of ​​the machine is 100 square meters and the height reaches six meters, which is equivalent to the height and size of two floors.

"How much human food can such a machine provide? What does its raw materials need?" Gu Han asked again.

"If saving some use is only to ensure the basic heat supply of human beings. Then such a machine's work 24 hours a day should be able to ensure the demand of about 20,000 people. As for the raw materials, it is enough to add enough water, then invest a lot of soil, and finally put the collected human feces into it!"

"What! These nutrient solution are actually made of mud and feces!" After hearing this from the science and technology department, some humans immediately felt disgusted and wanted to spit out the nutrient solution they drank yesterday.

"It's so strange!" The people from the Ministry of Agriculture said disdainfully that the vomited guys said, "The seeds are ripe until they mature. Are there any things needed to be mud and feces? What's so surprising about this? We humans rely on feces to continue."

OK, after the Ministry of Agriculture said this, more people vomited.

"In other words, if we can build 20,000 such machines within a month, can we ensure that everyone's food supply?" Gu Han interrupted the somewhat disgusting atmosphere and said directly.

"Yes, Your Majesty! As long as there are 20,000 machines and we are dispatched one million people to collect the materials needed to make nutrient solution, I can guarantee that the food supply of 200 million people will not have any problems!" The person from the Ministry of Science and Technology replied readily. He was actually bragging about this, but it doesn't matter if this bragging is done. With the current human situation, it is impossible to get 20,000 machines in one month.

"Is there any material to make these machines?" Gu Han asked again.

"This... Didn't you just say it... the materials used to make these machines cannot be produced at present..." The person from the Ministry of Science and Technology said aggrievedly, but before he finished speaking, he was directly interrupted by Gu Han's tough stern "I'm not asking you this, I'm asking you, do we have any raw materials used to make these machines?"

"I'm afraid this hasn't... it has turned into ruins, lying in a deep pit..." said the head of the Ministry of Science and Technology.
