There is no future in sight for this task, the loess slopes are now yellow, and the nuclear war has destroyed all complex life forms, but there are still some things that have not been destroyed, and the simpler things are, the stronger the vitality. Fruit flies, cockroaches, and these things have not been destroyed, and they certainly have not mutated into giant cockroaches. If you want to go back to the age of giant insects, unless the atmospheric oxygen level increases.

However, this place is not lifeless, in this westerly wind, nuclear dust has long been swept away in a thousand years, and in the northwest, where there is no plant protection, once a sandstorm blows, it can sweep away a layer of land above ground. Thanks to the sandstorms, if it weren't for the sandstorms, the high-radiation wasteland state here doesn't know how long it would last. After the nuclear war, only ten years later, the human beings who came out of the ground struggled to survive on this land, surviving with the unique resilience of the Northwest people, taking out seeds from the warehouse, digging buckets of water from underground wells, and trying to make a little bit of green.

Generations of humans died, and the next generation of humans began to wonder why they were doing it, but they continued as if they were following the ritual. In the gloomy loess cellar built in an unknown year, Li Ziming picked up a piece from a pile of yellow fluttering mounds. "Wiped it and nibbled it. It's a little astringent, and some areas have sprouted. By 21st century standards, this is an inedible sprouted potato.

Of course, people here do not eat it directly, but soak it in a liquid containing vinegar and then roast or burn it. Thinking about this kind of eating, Li Ziming was relieved, acetic acid and solanine can be decomposed when heated.

Looking at these subhumans behind him who were barely wrapped in clothes. Li Ziming smiled, even though his intelligence had deteriorated, he still firmly remembered the knowledge about survival and common use. Li Ziming was pleased with this sign of subhuman beings on the high slopes of the loess. There is a basic willingness to farm, although it is only the simplest planting, but it is still the willingness to farm, which shows that the most basic civilization attribute required by Ren Di has not been extinguished.

Although the subhumans in the wild are not as good as the subhumans in the coastal areas in terms of lifespan and intelligence, Li Ziming still has to thank this piece of yellow sky and thick soil. It is the cave here that gives the human beings in the loess a certain place to maneuver, that is, this loess flutters in the wind, allowing the nuclear dust to disperse with the wind within ten years.

Civilization is only when it is endangered, and people discover that the so-called gorgeous poetry scrolls, a series of works of art, and all the famous names engraved in history are flashy, and only the existence of the fire of civilization is the last word.

After arriving on the Loess Plateau, Li Zimin gathered a total of 40,000 human beings. Starting from the simplest habits, boiling water, and dressing habits, we began to teach these people to summarize the growth of potatoes under different light soil and water conditions, based on the local potatoes in the direction of planting. And recorded.

Of course, none of this is difficult, and the worst thing is to teach the text. This time, only 15 percent of people with IQ above the 60 or more mentally retarded threshold are employed. In other words, only 15% of them can articulate the complex information they want to express in words relatively clearly. However, this 15 percent, learning words, made Li Ziming have a rhythm of wanting to throw chalk.

Huge propellers and round planes fell from the sky, and when the helicopter fell, the subhumans who had been busy combing the land on the plateau looked up at the direction in which the helicopter fell.

After watching Ren Di walk down, Li Ziming, whose face was covered with wind and frost and dust, watched Ren Di walk down from the plane. The corners of his mouth grinned. Ren Di, who got off the plane, looked at Li Ziming's somewhat dry and molting face, and Ren Di was a little moved. It's clear that it's hard work here.

After stepping out of the plane, Ren Di asked, "How is the situation?" Is there any progress? Li Ziming shook his head, then nodded and said, "It's very hard." Ren Di nodded: "Let's talk slowly." ”

While leading Ren Di towards the underground passage of the cave system, the entire underground passage is supported by steel supports, and the walls are still yellow mud. In the vicinity of the tunnels, humans have been digging new passages with shovels. The method of excavation is to start digging from below, and then create a crack from above, and the cave soil is scheduled to collapse all at once. Several cubic meters of earth chips can be extracted from the tunnel at once, and of course this kind of excavation is very dangerous. If you don't pay attention, you will be buried by the landslide.

Seeing Ren Di's curious eyes, Li Ziming smiled and said, "Very hardworking." Ren Di nodded and said, "I just hope that this exists." Li Ziming said: "They have done their best. That's all they can do with enough food. Ren Di nodded and said, "Naturally, the genetic changes of human beings are based on five hundred years. Now I don't expect immediate results. It can be said that we have completed an unprecedented social experiment. ”

Li Ziming asked strangely, "Social experiments?" Ren Di said to Li Ziming: "You should be a historical line with me." Li Ziming nodded and said, "It's probably approximate." Ren Di asked, "Do you know the game of Fallout?" ”

Li Ziming nodded and said: "Naturally, you mean, the so-called nuclear war upper layer in the game conducts observation experiments on humans in the shelter?" Ren Di smiled and said, "I don't know what the point of the people in that game is doing this social experiment of one man with more than three hundred women, one woman with three hundred men, or only one person in the entire shelter." Social experiments, if you want to verify ugliness, why look for humans. ”

Li Ziming said: "What do you want to experiment? Ren Di didn't answer directly, and asked Li Ziming: "Li Ziming, how do you judge the quality of a weapon." Li Ziming said: "Make a preliminary judgment from the performance of firepower and maneuver indicators. Of course, it can't be so simple, and it needs to be further verified that the system is stable in various environments. and whether it is conducive to repair after damage. ”

Ren Di said: "What about a summary in one sentence? Li Ziming said: "It depends on whether it is easy to use in practical use." Ren Di nodded, and then asked, "What about the tools?" Li Ziming said: "It also depends on whether it is easy to use or not." Ren Di continued to ask, "What about genes?" Li Ziming was stunned, and then said, "The same." ”

Ren Di nodded and said, "I think so too." Whether something is good to people depends on whether it is easy to use or not. Only after using it can we confirm whether this thing is good or bad. Of course, if you don't, you never know if it's good or not. A person with genius genes who does not give his all to prove that his genes are good, but lies in bed. Then his genes cannot be proven to be superior. See why I value hard work so much. ”

Li Ziming took a breath and said, "You want to screen genes? Ren Di nodded and said: "I never think that excellent genes determine civilization, it should be excellent civilization that determines genes, our genes have already been screened by our parents, and the genes that are not suitable for hard work and wealth accumulation in the prosperous era have all been eliminated, and it is not a joke that a lazy man can't marry a wife." In troubled times, all races that were too delicate were eliminated in the disaster. Competition allows the good genes to emerge, but this kind of selection is too crude. ”

Ren Didi paused and said: "The current technology can read the genetic sequence. However, this kind of reading is only reading the sequence on the gene, and as for what the sequence on the gene decides, I don't know at all. Only by summarizing the commonalities of the samples in life and the commonalities in genes can we know what that gene determines? As for the genes of an excellent race, if you want to know where the excellent genes are, you can't find them at all by simply searching for them from a series of genetic sequences with the same code. This race must go all out to be excellent. ”

Li Ziming nodded suddenly: "That's why you ask for diligence." Only diligence can amplify excellent genes as much as possible. Analysis based on a large number of samples. in order to find a possible corresponding sequence. ”

Ren Di nodded and said: "Only we can do this thing, and if we can study the rise of a race without hesitation, then only if we are this race, we can do it with all our might." This is not a selection of tomato seeds, the seeds are treated with radiation, and then the selected seeds are nothing more than hypertrophied fruits. Humanity has also suffered from radiation now, but the effect we have to filter out is not not not afraid of death cannon fodder, or loyal allegiance to the race, what I want to screen out is the lord of heaven and earth. ”

Li Ziming took a breath and said, "Then the whole society does such an experiment? Ren Di said: "There is no choice. This time, I came to build a nuclear power plant and an insect breeding warehouse. Even if they are built, they will not all be open to subhumans. They must now have the ability to support themselves as adults. However, these facilities are used for the work of genetic screening laboratories. Modeled after your genes and mine, and the genes of all subhumans here. Completes everything. The equipment lacking in the project can be manufactured, and the huge amount of work of analyzing the genetic sequences can be distributed to the new humans of the Zhou Tian Alliance, but the most difficult thing is that the experimenters express their excellent motivation - diligence. ”

Li Ziming nodded and said, "The road is very difficult, but you say so, I am already relieved." There's a way out. Ren Di nodded and said, "I'll go to work first." ”

watched Ren Di walk towards the ground. Li Ziming looked at Ren Di's back and muttered: "This kind of life is endless, it's really terrifying." Teacher, I don't know if you're there. But when you work with him, you also find out what kind of person he is. ”
