Faced with this crucial conundrum facing humanity, all the participants in the meeting were sweating and did not know what to do.

This is why they are not in a hurry, this is the problem of feeding 200 million people, once they all starve to death, it is estimated that they will be demons for the rest of their lives. Everyone knows that this problem must be solved, but no one can come up with a solution...... They would rather go to a decisive battle with Yuan Kou than think about this damn conundrum.

"I wonder how our human ancestors solved this problem when the Great Destruction had just begun?" One of the sword-wielders said, apparently trying to find a solution to the problem from the experiences of his ancestors.

"At the beginning, a lot of food was stored in Old Yanjing City, and the ancestor had a natural dimensional pocket, so he brought all these foods with him, barely enough to eat in the early stage. After entering the gap of the passing year and the environment was a little safer, the ancestor organized the people in the gap to farm, so that he could barely get the food that could ensure the consumption of 100,000 people," said the flowing year.

"Yes, we can farm too!" Some of the participants suddenly realized, "We can reopen up a large area of fertile land, thousands of years ago, when there was no high technology, our ancestors could grow enough food with their hands to eat hundreds of millions of people, and now we can also use the most traditional methods to grow it!" ”

"That's right!"

"This is a good idea!" The sword-wielding's words instantly drew the approval of many of the attendees.

But soon some people retorted coldly, "As soon as I heard it, I knew that a guy who didn't understand agriculture at all would say it, even if the sweet potato with the shortest maturity period would take four months to grow and mature, and everyone would have starved to death by then!" ”

"Hmph, it's only four months, our food can still support another month, it's a big deal that everyone eats a little less, a mouthful of food should be eaten in four bites, everyone can boil it, and it can always support four months!" Immediately someone said.

"Yes, after four months, it is estimated that half of the population of 200 million people will not be left, you will be the murderer who killed 100 million people!"

"What's the solution, it's better than everyone starving to death!"

"That's enough, your ideas are so simple, do you think you can feed all of us in four months with sweet potatoes alone?" The agricultural expert who spoke first couldn't help but say, "If you want to grow enough sweet potatoes for 200 million people, you need at least three provinces of arable land." Where did we get so much land from me! ”

The moment of this agricultural expert made everyone lose their voices, and they couldn't imagine that it would take three provinces to cultivate enough sweet potatoes.

Even if the human race is at its peak, it only controls eight base cities, and the total land area of no more than two provinces is not enough, and now the power of the human race has declined to this extent, and the total number of sword wielders together is less than 20,000 people, not to mention the cultivated land of three provinces, even 1/3 of one province may not be able to control it.

"Well, there is no need to argue about this, agriculture is the foundation of our human race, and the cultivation of sweet potatoes and other fast crops must be prepared now, and the people of the Ministry of Agriculture will immediately begin to collect and control the seeds of all the crops I have now, and put together a whole set of textbooks that can make ordinary people learn how to plant them immediately after reading them...... The number of words is not too much, and this textbook must be controlled within 500 words, otherwise no one can understand it! Gu Han on the rostrum spoke, and the people from the Ministry of Agriculture immediately nodded in agreement, and 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 come from?

"Ladies and gentlemen from the Ministry of Science and Technology, are all the nutrient solution synthesizers damaged? Not even a single intact? Gu Han asked the head of the Ministry of Science and Technology.

"That's not it, there should be two intact nutrient solution synthesizers in the gap of the passing years!" The head of the Ministry of Science and Technology said after recalling it.

"Rin, could you please go and get the machine?" Gu Han turned his head and said to Liu Nian Rin beside him, Liu Nian Rin nodded, and the whole person disappeared directly into the venue, and after waiting for about half an hour, Liu Nian Rin returned to the venue with the two machines.

Gu Hanzai carefully looked at this machine and found that the cross-sectional area of this machine was 100 square meters, and the height had reached 6 meters, which was equivalent to the height and size of a two-story building.

"How much human food can such a machine provide? And what does he need for raw materials? Gu Han asked again.

"If you save some use, you just need to ensure the basic heat supply for human beings. The 24-hour non-stop work of such a machine 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 a lot of dirt, and finally the collected human feces! ”

"What! These nutrient solutions are actually made from mud and dung! "When some humans heard this sentence from the tech department, they immediately felt sick and wanted to vomit out the nutrient solution they drank yesterday.

"Rare and weird!" The people from the Ministry of Agriculture looked at the vomiting guys with disdain, and said, "When the seeds go to the ground and mature, don't the things they need are mud and dung?" What's so surprising that we humans rely on feces to survive. ”

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

"In other words, if we can build 20,000 of these machines in a month, will we be able to feed everyone?" Gu Han interrupted the somewhat disgusting atmosphere and said directly.

"Yes, Your Majesty! As long as we have 20,000 machines and send a million people to collect the materials needed to make the nutrient solution, then I can guarantee that there will be no problems with the food supply for 200 million people! The person from the Ministry of Science and Technology replied cheerfully. He was actually already bragging, but it didn't matter if he was bragging about it, with the current human condition, it was impossible to get 20,000 machines in a month anyway.

"Are there any materials to make these machines?" Gu Han then asked.

"This ...... Didn't you just say that...... The materials used to make these machines cannot be produced at present......" The person from the Ministry of Science and Technology said aggrievedly, but he had not finished his words, and was directly interrupted by Gu Han forcefully, "I'm not asking you this, I'm asking you, do we still have the raw materials to make these machines?" ”

"I'm afraid it won't be ...... It's all in ruins, lying in a deep pit......," said the head of the Ministry of Science and Technology weakly.

"Then there you have it!" Gu Han's brows relaxed, and he immediately ordered the person in charge of the Ministry of Science and Technology, who had already entered a large number of sword wielders, directly to the bottom of the pit and transported all the raw materials for the manufacture of this nutrient solution synthesizer.

Although I don't know why Gu Han gave such an inexplicable order, but at this time, Gu Han's prestige was monstrous, and no one would question Gu Han's order, so the people from the Ministry of Science and Technology immediately took some sword bearers away, and after less than an hour, these sword bearers came back with colorful metal balls of various strange shapes in their dimensional pockets.

"What is this?" Some people in the venue couldn't help but ask after seeing these strange metal balls.

"These are the raw materials needed to make a machine!" The person in charge of the Ministry of Science and Technology said with a wry smile: "It's just that all these metals have melted under the action of high energy, and finally they all converge into this metal ball one by one." With the only scientific and technological power we have left, we can't separate these metals again, and we can only bring them all according to His Majesty's request! ”

"Excellent! That's enough, you're doing a great job! "Bringing these metal balls directly over was originally a helpless move by the Ministry of Science and Technology, but I didn't expect it to win Gu Han's praise, which made everyone startled...... "What does Gu Han want these metal balls mixed with all metals?" Does he still have the ability to separate these metals out of thin air? ”

As soon as such a sentence came out of everyone's hearts, they saw Gu Han's hand move forward, and one of the basketball-sized metal balls flew directly into Gu Han's hands, and then the thing that blinded everyone's eyes happened, only to see that after the metal ball was held by Gu Han in his hand, this metal ball that was hard to the extent of alloy, at this moment, it was as if suffering from osteoporosis, and countless powders began to fall off from the metal ball.

And these falling powders do not simply fall to the ground, but as if they were pulled by something, they are divided into hundreds of different thin lines, drifting towards their different landing points, and finally piled up on the ground, forming a small pile of powder.

At first, the metal ball did not powder quickly, but as time passed, the metal ball began to shrink rapidly at a speed visible to the naked eye, and those different thin lines became thicker and thicker. In the end, only ten minutes later, the basketball-sized metal ball completely disappeared into Gu Han's hands, turning into hundreds of piles of powder.

"Oh my God, this is iron powder, this is iron powder!" An ore expert from the Ministry of Science and Technology suddenly pounced on the largest powder pile among the more than 100 powder piles, directly grabbed a handful of powder, put it in the palm of his hand and looked at it carefully, then put it on his nose and sniffed it, and finally even licked it with his tongue on these powders, and finally the whole person shouted excitedly, "This is iron powder, this is high-purity iron powder...... Oh my God...... I've never seen iron powder of this purity...... Oh my God, how is this possible! ”
