The bgm music in this chapter is TowardstheLight

The future planning of the entire Loess region has been set step by step, in the past, there was no reliable population, unable to engage in complex industrial and peasant labor, and now the population is still scarce. At least fifty years from now, if the alliance with Zhou Tian turns against each other, Ren Di doesn't think that the Loess Region has much chance of winning. The productivity gap is not something that can be bridged in the short term.

Nowadays, most of the technical work in the entire Loess Region is done by materials and talents supported by the Zhou Tian Alliance, including the most important factory food production, which is now the use of the ground to absorb solar energy to obtain organic matter. For example, in the loess region, growing potatoes to obtain starch from potato tubers is just the main way for aspirants to produce food. However, this is not the mainstream of food production in this world, and it is precisely because of this that the three major powers have not developed inland.

The mainstream of this world is to convert organic matter such as seaweed or pasture into edible substances. The first is to raise edible insects, the whole insect breeding room is like the chicken farm in the past, a can-sized space grows a chubby pupae, these pupae have been selected for generations driven by economic interests, very fat and can only survive in a high-oxygen environment. Feeding food at the head and excrement at the tail in a can-sized culture chamber, the whole bug acts like an efficient machine that converts fiber into protein. When the weight of the insects in the culture chamber grows slowly, the fat worms the size of a child's fist will be disemboweled, washed off with salt water, and turned into jerky or protein # powder after disinfection and drying.

As for the second food production system, the plant fiber is hydrolyzed with genetically modified microorganisms, and the efficiency of converting starch can reach 30%, and the other by-products are alcohol and yeast protein.

In this era, the territorial value of the interior is much less than that of the waters of the continental shelf. However, these two high-level modes of grain production, so far, are only a set of security systems in the loess region, and cannot form a scale. Not because of the equipment, but because of the people. Insect feeding requires sterilization of the feed, and the oxygen supply system in each room needs to be ensured. Once there is a violation of the system, oxygen leakage or something, well, that scene is definitely not a small accident.

As for the second type, which requires strict aseptic production, all raw materials to products must be meticulously disinfected and sterilized. These were not possible for those who aspired to do in the past. It must be operated by highly trained subhumans.

Prior to this, the aspirants could only be self-reliant in the agricultural age, and in the industrial age, they could not participate in the main industrial and agricultural production and manufacturing systems. Therefore, there is an upper limit to the population of the loess area, and the population of four million people depends on potato cultivation to live on this land, once the land cannot be satisfied. Then the food supply can only be guaranteed in a way that the aspirants cannot participate in.

However, once this method is activated, it means that the aspirant is not supporting himself in this world. In the case of the material operation of the entire loess region, this is far from the point of life and death. However, if this state is maintained for a long time, inertia will gradually lose the sense of crisis in the existential crisis, and the inertia of subjectively believing that we can rely on the loess area to supply food will arise.

Over the years, Ren Di has preached the concept of yearning for the loess area, and there has never been any happy life, happy production, and happy learning. Life is to verify the meaning of one's life, production is the capital to plan one's survival in this world in the long run, and learning is to understand the world and read the strategy of previous wisdom to survive in this world.

Now it is clear that there is an existential crisis in the loess region. It is a crisis that the aspirant needs to face. It is not the new human researcher in the region that the subhuman worker has gone from being a guide to a master, worrying about the survival of the aspirant.

Therefore, this migration within the loess region is not a short-term economic pressure, but to alleviate internal contradictions. The locust plague has destroyed the fruits of the labor of the year-seekers, and at this time it is not time to do nothing and let the year-to-seekers watch in despair, but to do something.

Qinghai Lake, the largest saltwater lake in Chinese mainland. It is estimated to be 4,000 to 5,000 square kilometers. The average water depth is 21 meters, and the maximum water depth is 31 meters. Now this is the new target of the loess area, a dozen meters long hard plastic containers, extending from the surface of the water to the bottom of the water, about hundreds of plastic long containers, connected to the same base at the bottom of the lake. A pedestal connects hundreds of long plastic containers, like a pinch of giant aquatic plants floating in Qinghai Lake. At the bottom of the lake there are an average of 30 meters of intervals of one base, each of which is connected by pipes. The green liquid content of the plastic drum is controlled by means of a base.

As for the green liquid inside, it is the lake water with a large amount of green algae, and the special "plants" composed of hundreds of bases and clusters of green plastic containers make the lake area green. A large amount of sunlight is poured into the water, absorbed by the green algae in plastic buckets, and then grows, and the pipes connected to the base are injected with nutrient-rich lake water, which is then pumped out and filtered through a semi-permeable membrane into a factory near the lake. It is then discharged into the lake water.

This part of the filtered green algae water is discharged into the lake water, and the residual nutrients are likely to cause blooms. However, from an economic point of view, residual nutrients are not wasted, and in fact the function of the pontoons is not to prevent the water from being polluted, but to concentrate the fertilizer on the water where the algae grow. Most of the algae in the culture tank are used for photosynthesis. The only bad thing is that when the bloom covers the surface of the water, it will block the absorption of sunlight by the transparent pontoons. In the final analysis, this kind of technology is the technology used by Zhou Tian Alliance in marine planting.

This technology requires a large amount of water to ensure the circulation of the water body, and although there are residual nutrients in the discharged water, the rivers do not emit a staggering amount of nitrogenous substances into the sea because there is no large cultivation industry on land. With the action of ocean currents, the phenomenon of red tides in the ocean occurs very rarely. The separation seaweed plant is at the edge of the continental shelf, where wastewater is discharged directly into the deep sea. So basically there are no drawbacks.

As for Qinghai, this body of water is still too small compared to #sea.

As for the ecosystem of Qinghai Lake? Since the cobalt bomb kicked up radioactive dust in the west, the higher animals and plants in the water column have been extinct. Such a set of algae cultivation technology has existed in the 21st century, but it dared to be used on such a large scale, and only in the era of nuclear steel, when animals and plants were extinct. The light-transmitting nature of water bodies allows humans to build multi-layer planting systems that absorb sunlight at a low cost. Of course, if you use a skyscraper to increase the utilization rate of absorbing sunlight, it is also possible, but the cost of the building is too high. Far less cheap than a plastic bucket in water.

As for the dirty plastic bucket, drain the liquid inside, the base automatically closes it, spits it out, and the empty bucket floats directly on the water, and is transported by ship to the factory to automatically clean the green attachment on it. The installation is to fill the lake with water and dock directly with the base under water.

The first advance team in the loess area next to Qinghai Lake was installing pedestals imported from the Zhou Tian Alliance, and diesel-powered boats set off waves on the lake. The wetsuit-wearing aspirant controls the machine to tie a fixed steel drill to the bottom of the lake, and then attaches the base of the auxiliary lifting to the steel drill. Then carefully dock the crumpled and curved FRP pipes with the bases, and then fix the wrinkled pipes (the structure of the exhaust pipe of the smoker) spread on the bottom of the lake at the same time. The whole work is like an underwater team of migrant workers.

Well, the Loess Region has worked hard for decades to carry out the sub-human completion plan, and the thousands of sub-human beings who have been trained are doing this kind of work. Moreover, among the millions of yearning people in such a living loess area, only this group can do it.

These young aspirants are very enthusiastic about completing such a work, but Zhao Jingwen shook her head in her heart when she saw all this, from the current economic perspective of Zhou Tianhemeng, the fruits of sweat are too disproportionate.

Zhao Jingwen's mood has fluctuated significantly recently, and the aftermath of Sun Dingchuang's exit is still continuing.

The waters of Qinghai Lake ripple with the operation of engineering vessels, from the rising sun to the stars dotting the sky. When the day's work was over, Ren Di looked at the lake reflecting the starry sky, and a little impulse flowed in his heart. Jumping into the lake with a plop, his hands and feet paddling in the cold lake water in an orderly manner, at this time, the base had been installed and the electrode light was turned on at the bottom of the water. The little lights, although bright, provide a light source for the bottom of the lake. It's not very bright, but without this little bit of light, the deep water of the lake will give people a sense of fear. But now this unknown darkness at the bottom of the lake is instantly gone.

Seeing Ren Di swimming freely in the lake, the young people who walked from the Loess District Laboratory to this world for the first time also carefully tied an inflatable bag to their arms and jumped into the lake. Very unique experience.

On the water, Ren Di couldn't help but raise his water-stained hand to the sky, but the moment he raised his hand, Ren Di's eyes and nose were submerged by the water. You can taste the saltiness through your nose.

Ten minutes later, Ren Di swam ashore. Lying on the shore covered with stones. After a while, Zhao Jingwen also walked here, her eyes silently looking at the line where the lake and the starry sky met. Ren Di said: "Homesick? ”

Zhao Jingwen's expression stiffened and turned to Ren Di and said, "Home? Do I have one? Ren Di sighed and said, "I'm sorry." Zhao Jingwen said: "You came to me just to talk about this?" Ren Di nodded and said, "Yes, I just suddenly felt very sorry for you." ”

Zhao Jingwen turned her gaze back to the lake and said, "I am no longer the little girl I was at the beginning, this sentence, for me, is as cheap as a chapter of scratch paper." Ren Di sighed and said: "That's right, you were forcibly taken out of your original living environment and stuffed into this sacred, but ethereal career." An apology is really cheap. ”

Zhao Jingwen looked at the returning yearning boy by the lake and said, "Are you still sure that you are walking in the future of this world?" Ren Di closed his eyes, if it was dark ten years ago, it would be nothing to grit his teeth and go down. And now, when many evolutionary officers came to this world, the means used, it cannot be denied that this world is advancing, taking Sun Chiyong as an example, when the population of the human race has been greatly reduced, the growth rate of the new population of sub-human beings has been twice that of twenty years ago. This is reflected in the fact that the level of mechanization in the army is getting higher and higher. According to this trend, most of the times human beings will not even be able to sit as cannon fodder in the army. Sun Chiyong's policies are vigorously enforcing the elimination of inferior genes in humans.

Thinking of this, Ren Di showed a wry smile on his face and said: "A long, long time ago, I was tired of hearing it, you look at other people's words and the like, I often heard it when I grew up, and the public praise of the group I belong to is the hope of our school, and they are our future." I've heard these words too much. So much so that I got used to being in the middle, in the middle of the back. I had never won the first place in any group until I was twenty years old. ”

Ren Di smiled and said: "I know everything, I know that this first position is not for me." If I pick 10 percent, I usually realize that I have a 90 percent probability of being in that 90 percent. The only thing I am fortunate enough for is that at the age of twenty I already know my destiny. ”

"Cheap, not the first 10 percent is cheap. That's right, I'm sorry to you now for cheap. ”

Zhao Jingwen looked at Ren Di and said a little mockingly: "Cheap, hehe, I don't know what you are doing, what you are insisting on, but I don't understand, I don't understand, no matter how hard I try, why, can't I have a place in the eyes of the people I care about?" You said that he had to leave me, but at the end of the day, I felt that it was all perfunctory, and you were perfunctory to me from the beginning. Unconsciously, Zhao Jingwen already had tears on her cheeks.

For the first time in this world, Ren Di felt that he was speechless in the face of a person. However, after a minute, Ren Di's eyes gradually changed from helplessness to calm and then to silence. Ren Di turned to Zhao Jingwen and said: "You are right, use, from the beginning, I didn't have the intention of making friends with you, from the beginning I was analyzing you with human preferences, so that you can make a choice that is beneficial to me." ”

Speaking of this, a wry smile flashed on Ren Di's face, and he said: "It's just that you are a beautiful girl, very beautiful, and your identity is a nobleman in this world." The aristocratic girl cherished by the stars and the world, your definition in this world is gorgeous and precious, and I don't want to admit it in the past world. Now I admit it. I admit that I, as I affirm me, am taking advantage of you. ”

Hearing this, Zhao Jingwen pulled out her dagger and aimed it at Ren Di. Ren Di looked at the dagger that flickered coldly, and said calmly: "First, you can't kill me, and second, the truth is not good, so that I don't dare to admit it in the past." Thirdly, from today onwards, you are pure in my eyes. No more flashy packaging. ”

Zhao Jingwen slowly put down the dagger, Ren Di turned to leave, and walked ten meters, Ren Di suddenly stopped and said to Zhao Jingwen: "Starting today, I don't want to use you." ”
