"The fertility of the human race needs no need to mention, the fertility of the beast race... is even stronger. Fortunately, the human race is difficult to cultivate, and the beast race is even more difficult to achieve ten times or even more, so both sides are balanced."

"That's it... In fact, this world is now full of people?" Li Yifei said.

"Crowds are overcrowded? This word is right. Now it is really overcrowded, but it is not because it can't live in it, but because the land is not produced so much, and there is not enough food. If there are too many people, it seems not enough!"

Li Yifei, who came from the earth, still finds a little difficult to believe. In this world, his cultivation level is considered low-level. So there are many people with great magical powers. Can't even those people deal with the problem of food shortage? Even if there is a problem with the land, it is not so bad, right? When Li Yifei thought of this, he couldn't help but feel a little puzzled, and said, "Uncle, it's hard for me to understand that there is not enough food. There are less land production, and that kind of thing. Isn't it because no one cultivates it?"

"There is never a shortage of people who farm. Alas, it's just that there are fewer outputs and more diseases. The energy of the land is there. You can't water it with the spiritual spring like me, right? That's too luxurious, let alone the spiritual spring is even more precious."

"Okay..." Li Yifei couldn't help but sigh, but when he thought about the food yield in ancient China, he could understand that the food seeds cultivated naturally and selected from modern technology, and even sent to space for gene transformation, the output is much higher. Not to mention, just the rice god Yuan of China, the hybrid rice and super rice he and his team have studied over the years, and even sea rice suitable for seawater irrigation. These are constantly refreshing and breaking the record of rice yield per mu. They can be said to be the contemporary rice god. In ancient times, they were all worshipped in temples.

It is precisely because of the development of science and technology that the earth can carry more than 7 billion people, and it is even said that it can reach 10 billion. Of course, the population is better to have a smaller population, because the earth has so much petrochemical energy. If you use a little less, you will use it all one day. What should you do then? The research and development of new energy seems to be a problem for the time being.

Well, I thought too far. Li Yifei shook his head. Now I see that I was at least not in the wrong place, it was this world, and I also knew a little secret, which was in confronting the mysterious disappearance of the cultivator in the Song Dynasty. It seems that the top cultivators at that time all came to this world and destroyed all the martial arts and other things in that world.

"Cultivators rely on qualifications. Not everyone can practice. Although powerful families, sects, and even individuals can use spiritual medicines or even top cultivators to change their destiny against the will of heaven, but that is a minority after all. For most people, if they are not qualified enough, they cannot practice and become ordinary people. This world... is actually like that world, it is very cruel for ordinary people. They have a short lifespan and are struggling to live for the rest of their lives. In order to fill their stomachs, to survive, to make their descendants stand out and become cultivators!" Xiu Qi said this, and sighed, and said, "The wishes of those sages are very good. They want to let cultivators enter here, leave a space for ordinary people to live and practice better. However, they did not expect that reproduction would occur, and there would be qualification problems!"

Li Yifei understood more and was grateful that the people on earth opened another science and technology tree, which was a real science and technology tree, from agricultural civilization, from feudalism and slavery to a relatively civilized modern society. Otherwise... the population of seven billion is probably not able to bear it on the earth. Of course, it is also very likely that if this number is not reached, there will be war, death, and large numbers of deaths from hunger, disease, and war.

It seems that we also have to thank the cultivators for leaving, forcing ordinary people to make progress in order to survive. But I didn’t expect that the black humorous thing is... When the cultivators arrived here, they were still in war and still bloodthirsty. At the same time, they also created many ordinary people and were eliminated.

It was nothing, it was good to be peaceful, but unexpectedly, because of the years of melee when I came, the land was destroyed, the earth veins were destroyed, the spiritual springs were broken, and now it turned into a food shortage... This is so dramatic. Li Yifei never thought that people in this world would have food shortages.

Of course, this has something to do with the seeds of grain. After all, there is no optimization, breeding, even gene transformation on the earth, as well as various fertilizers and pesticides. This is not the case in this world. This can be seen from the conversation with Uncle Xiuqi. Since it is not, it is difficult for grain crops to grow so well and bear so many fruits.

More importantly, people in this world need more energy, not only through cultivation, but also from food. This is why Li Yifei became more eager to eat after coming to this world. Why did he have to eat something when he was hiding in the forest, such as those chicks, which were forced to eat. The better the land, the better the food will be produced, rich in spiritual energy. This is a good food for the cultivators. Otherwise, the general land produced is useless to them, and they cannot eat dozens or hundreds of kilograms in one breath.

The higher the cultivation level, the stronger the demand will be, and the higher the quality of the requirement will be. This is the current contradiction. Like black humor, after Li Yifei heard it, he just nodded and sighed.

It seems that the earth has embarked on the right path and realized the true meaning of the world. Science, whether it is physics, mathematics, biochemistry, or even other disciplines, is exploring the truth. Although the cultivators are strong in individuals, they are another path. This path seems... a little bit impossible, so it doesn't matter to top cultivators. Whether it is the human race or the beast race, even if they are made into sieves, they can occupy good places with their strong strength. The human race's territory also has sufficient spiritual veins, but now they are almost occupied by sects and families, and few are owned by ordinary people.

If ordinary people want to survive well, they must rely on these sects and families. There is no saying that the emperor here, they rely on sects and families to live. If they don’t want to rely on them, it will be difficult to survive, at least they must live at the bottom.
