In addition, there are many rules that limit the upper limit of human beings. For example, in the human body, that is, our flesh, in principle no organ is wasted, and there is not even room for other organs. Before the creation of human beings, the function of each organ has been designed, and the sequencing of each organ and the results of all combinations have been carried out very large calculations and demonstrations, and even the maximum power and life of each organ have been strictly calculated and evaluated. The initial design idea for this ethnic group or race is that the container has a certain service life and can reproduce in a certain period of time, so that the container containing souls will not expand indefinitely, and the number of this ethnic group will be limited to a certain number. The stable number of ethnic groups will provide a steady flow of souls for the battlefield outside the cage. And these souls with certain knowledge will be implanted in higher machines or containers as consumables of war; Whenever the intensity of the battlefield and war increases, a large number of lives and souls can be harvested in a very short period of time to supplement the needs of the war by adjusting the change of the environment and creating natural disasters.
However, at the beginning of the design, a lot of calculations and considerations have been made as much as possible, but after the development of a long time, some unevaluable variables still occur, such as environmental changes and the accumulation and iteration of substances of different properties absorbed into the body. The human body also has some changes, which are called evolution or degeneration. The most obvious manifestation of this evolution or degeneration is cancer. This is a phenomenon that goes beyond the original creation rules.
