Threshold

This is a certain characteristic of the world that has been acquired through the observation of the real world and having it magnified.Here, there are four criteria——Wealth, beauty, power, taste，The absolute and clear differentiation produced.——People who live in good houses and people who live in poor houses.They live in the world and the underground world ，Although it is unequal, it maintains a certain state by mutual restraint.. However，In this seemingly calm state，Hidden in a variety of potential crises.How to maintain the balance of the two party in this extreme state of the world？Here is the beginning of an inquiry about this. In this world，People living in a good house need to work for no more than 4 hours a day，For the rest of the time, they usually get a sense of pleasure by use some kind of high-techlong-distance crime against people living in poor houses and observing the reaction of people living in poor houses to being violated..The glass of the poor house is a special single side transparent glass. It can be seen outside, but it can't be seen outside.（I don't know who built it），For people living in a good house to observe the life and the process of being infringed on the people living in a poor house. Pleasure is the lowest spiritual guarantee of the world's human survival. Besides，Green plants are also an important thing that makes people happy. In this world, the number of green plants can't be increased.（The young seedlings are difficult to obtain because of the new material technology, and the young seedlings are difficult to adapt to the environment for survival and growth.），But they have a very important role, such as reducing the temperature of the air, increasing the humidity of the air, and reducing the huge amount of the surroundings from the sun.（And some of the harmful things）Ultraviolet radiation and so on. But people living in a poor house usually take at least 15 hours a day to work..Their main work is to maintain their roots. For them, green plants are still very important beliefs in life, so though they can hardly get any rewards.（Except for mental pleasure, although the roots bring much less pleasure than the crown），Every day, they maintain their roots in a desperate way. This behavior also ensures that people who live in a good house can enjoy the environmental optimization and individual spiritual pleasure brought by the green plants. Besides，People who live in a poor house can't get out of the ground above the house..Their outdoor space is about 500 meters underground，There is a reflective city with access to poor houses on the ground.Because of the distance, they usually live in the ground. But the soil under the ground is very wet, and they often suffer from skin diseases. People living in a good house have very high technology.（various），So that they are very picky about all kinds of daily necessities.Slightly flawed items will be discarded, through some underground passages into the world of people living in poor houses..These items that are discarded by the people living in a good house will be the main source of the living resources of the people living in the poor house. However，There are some crises in this seemingly stable world. The truth is that not everyone living in a decent house has mature conditions of crime or good opportunity. In the neighborhood of some decent houses, no shabby houses are located or within the view. Therefore, they will not be able to commit crime against those residing in the poor houses, or observe the reaction of the victim in the shabby house when infringed upon, leading to less sense of pleasure for them. As a result of the accumulation of their internal unpleasantness, the destruction of social order might be caused, such as directly committing crime against those who live in the decent house. It is the first problem. What is more, based on the fact that the people dwelling in the decent house tend to cast off the defectives at a relatively fixed location (mainly in the trash can), the obvious phenomenon of compact communities gradually takes shape among those in the shabby houses in the underground world. Neither the high population density nor low acquisition rate of resources is conducive to the enhancement of sense of happiness for the people living in the poor houses. As a consequence, part of those residing in a decent house cannot obtain adequate sense of joy due to the shortage of population living in the decent house in the neighborhood to fulfill their demand of necessary criminal activity, which is the second problem. The excessive ultraviolet (uv) radiation in the sunlight constitutes another problem. For some houses, the anti-resistance to ultraviolet is not strong owing to the larger window. In this case, even those living in a decent house keep staying indoors, they are still under the threat of skin cancer. The level of appearance is one of the four criterions in terms of the classification of people. Because of this, people whose level of appearance lowers due to the skin cancer would be discriminated against among people living in the decent houses. Over time, significant class differentiation is probably going to emerge among these people living in the decent houses. It is also highly risky without the separation of physical space among people of different classes, which is the third problem. In the over-ground world, the distribution of green plants is rather irrational. Near the area of some large expanse of green plants, few decent houses are located. Under the circumstance, people cannot make the most of the environment optimization and the ascension of sense of pleasure brought by these green plants. Although the green plants play a role in the resistance of a large amount of ultraviolet light, it is still harmful to the human health to stay outdoors for a long time. That is why nobody would deliberately step from the house beyond the impact range of green plants closer to the green plants area and stay for long. On the other hand, the sense of enjoyment of these people is not strong enough to maintain their current state of satisfaction. It is the fourth problem. In this world, the reversal of class is nothing impossible. There exist two plots of ground that are likely to crack when the predicted earthquakes takes place. In the event of an earthquake, the predicted crack befalls and those living in the poor houses might access to the world on the ground from the surface crack. It would be severe disturbance to the order of the world, which is the fifth problem. In order to make the world a more stable place in which people are more blessed, some designs have been made aiming at the afore-said problems. The designs were intended to heighten the sense of happiness of people living in the decent houses and poor houses, so as to maintain the stability of the world. It is a great collaborative design After some changes, people living in good houses can go deeper into the underground world on a short vacation, and observe people living in poor houses more closely and commit crimes against them. Because the distance is quite short, the enhancement of sense of pleasure was also remarkable. At the same time, people living in good houses can control the casting location of defectives. It not only facilitated their crime-committing, but also scattered the distribution of people living in the poor houses. Meanwhile, by virtue of this fresh and interesting mode, the quantity of defectives increased markedly for the lower world among people living in the poor houses, while the quality of life of people living in the poor houses rose substantially. . Additionally, people residing in poor housing have had an access to some ground-based areas since then, which are embraced by the green plants and previously were not fully utilized by the ones residing in the good housing. People residing in the poor housing shall be also able to feel joy and comfortable environment brought by the green plants here. In addition, those living in good housing will hide themselves into criminal space nearby and put inferior-quality product there to observe condition of people who reside in poor housing hurting each other when seizing these inferior-quality products or feel joyful for committing high-tech remote crime, while those residing in poor housing shall gain more living resources. For those predicted seismic fractures, some pathways are set up. These pathways are directly connected to the position described in the previous paragraph, however, some symbolic symbols with deterrent effect are arranged in the pathways to achieve the same spiritual guidance as a church roof (nothing but the opposite). Only those, who reside in poor housing and pass mental test in the pathways, have a chance to go for the ground and gain more and better living resources (and suffer more violent and frequent crimes). After trying everything, what people need is the God. To make these facilities fully utilized, people are very intimate to set up an one-on-one pathway on the window of good housing to ensure that everyone living in a good house can directly reach above entertainment venues without exposure in sunshine. To enhance capability to resist UV ray, pathways connecting facade is joined by some UV filter membrane. In short, with great collective efforts, some subtle changes have taken place in the world. People seem to live happier, and class relationships are more stable.
