If it is told chronologically, the story should look like this: a highly developed civilization is ready to build an experimental space-time, and first they have to build a mathematical model of the experimental space-time to provide a theoretical basis for the experimental space-time.

In the spatial dimension of this model, the developed civilization adopted the naïve model of the round sky and the place, and changed the two basic physical parameters - gravitational acceleration and the proportion of oxygen in the air.

In the time dimension, the developed civilization set the initial parameters for the human world, based on the antiquity in the real world, with slight modifications and deletions, so the experimental time and space had an ancient era, with the background of the times, a new era was officially opened, and a huge era fault appeared.

People in the experimental time and space absorbed the knowledge of the ancient times to form a set of people-oriented perceptual cognitive system, and did not form a modern science based on the concept of matter, because the gravitational acceleration was too small, and a closed and high-pressure state could not be formed under the earth's crust, so the catalyst that inspired modern science - oil - did not appear, and the Mohist mechanism had no power source, and could only stay on the strange and obscene skills, which was called the fine branch end of the stream.

In order to reduce the interference to the world, the developed civilization guides the world through the heavenly burial and the oracle of heaven to guide the direction of human development, but no matter how stable a system is, there will always be unstable elements, in the human world, a practitioner in order to explore the truth of heaven and earth, appeared in the sky, causing the first space-time crisis, the developed civilization skillfully lifted the first space-time crisis, and improved the mathematical model of experimental space-time, so that the world of the round place rotated at one point, so that the aurora appeared in the world, and a rotating magnetic field was generated, and there were no more people in the world who traveled outside the world to appear in the sky。

However, the developed civilization does not know that the second space-time crisis is also quietly being born, and some people, through self-exploration and thinking, are ready to use reverse methods to tell the people of the world that there are heavenly people above the world who overlook and monitor the world, destroying the unconscious nature of the world.

The developed civilization had to take action and guide the heavenly people above the nine grades to enter Tai'an City in the way of heavenly oracles, and finally the heavenly victory was won again, imprisoning the culprit on the snowy mountain.

During the blank period of ten years, there was no more interference in the affairs of the world, until someone died in front of the flowerbed of the Sage Academy, the situation in the world was suddenly complicated, and the number of times the heavenly people interfered in the world became more and more, and finally the masters of the world gathered in the snow mountain.

"Li Yuanying, although we are observing you from a high place, we have given you the greatest freedom within certain ranges, you can act according to your own consciousness, you can read and write, talk and chat. Freedom is not an absolute concept, freedom is always relative, and unfettered freedom exists only in illusions...... I don't like to put us against you, because that is a stupid and superficial cognition, I personally always admit that people in the world have equal human rights with us, and believe that heaven and earth are a complementary relationship, we provide a basic and stable space environment for experimental space-time, and the experimental space-time is also silently complementing the sky, through observation and testing, the experimental space-time can produce more than 40 academic works and more than 100 high-level papers every year, from which there are countless direct or indirect economic benefits, we thank you, thank you from the bottom of our hearts。 Catherine said, bowing deeply.

Standing in the main hall, Li Yuanhao pondered the words Catherine had said, his ears began to buzz constantly, his mind swelled, and then gradually calmed down, some things could not be changed, he could only accept: "What else have you done? What other means have you done to spy on the world? I don't believe that you have only done those things!"

Catherine slowly raised her head, her face showed a little hesitation, as if she didn't want to mention it too much, her mind struggled, and finally she sighed: "There is nothing to hide from you, you guessed right, we have another means of observing the world besides the acacia tree, and you should be very curious about why I have the same appearance as you, and you will also be very puzzled about the relationship between you and me." ”

Stretching out his hand in the air, an acacia tree jumped into his eyes: "There are thousands of people in the experimental time and space, and the huge base has caused huge management difficulties. ”

"Does this have anything to do with you and me looking the same?" Li Yuanhao wondered.

"The relationship is on the inside, not on the surface. Catherine said: "The purpose of human practice is to improve oneself and pay attention to self-sublimation, but the self here is not small enough and microscopic, staying on the surface, but we are different, we have a rigorous scientific system, so our understanding of people is much higher than yours, in order to avoid involving too many terms and concepts, I will not talk about the process, only the conclusion, we can accurately locate and monitor the people in the world through genes." ”

"Genes?"

"Yes, genes. Catherine's fingers moved slightly, and the acacia tree in the air twisted and deformed, forming a double helix spiral shape: "This is the gene, the child and the parent look similar, the reason is because of genetic inheritance, the gene inherits the characteristics of the parents to the next generation, it supports the basic structure and performance of life, stores all the information of the process of life, race, blood type, gestation, growth and apoptosis, human birth, growth, decay, disease, old age, All life phenomena such as death are related to genes, which have material properties and information properties. There are many differences between humans and animals, and if we want to distinguish them from the most fundamental point of view, genetic differences are the best answer. The genes of the same species have the same gene sequence, and the similarities between them are controlled by genes, and the differences are also controlled by genes, so for a long time, gene sequencing is a vast project for human beings to understand the world and the mystery of life. ”

"Even if you can decipher the so-called genes, so what, the genetic ordering should be a fixed sequence, which will not change from individual to individual, just like you said that the physical parameters, objectively real, do not change by the transfer of human consciousness and the different categories of objects, so the genes ......" Li Yuanhao's words came to an abrupt end, since they can change the physical parameters, why can't they change the genetic sequence, if Catherine is telling the truth, they can completely set any genetic sequence they want in the human body, this is a deeper level of monitoring than the acacia tree.
