Under such circumstances, breaking down the normal external body—or rather, the outer shell—to increase the fluctuation or efficiency of energy simply means accelerating the rate at which energy flows outward. At the same time, one must study the nature of this energy. However, infinite dismantling is meaningless. For instance, there is the crazed, genuine manifestation seen in a certain island nation; crucially, it becomes truly disgusting once adapted.
To sum up, immortal-type creatures generally have a huge impact on the world, even carrying a certain degree of contamination. After all, where there is one immortal, given the chance, there could soon be a whole group of them. Therefore, if the universe or the world itself possesses a will, there is a high probability that it will consciously or subconsciously limit the emergence of immortality. After all, this is roughly equivalent to having a cancer cell multiply inside the body.
Yet, where does the abnormal proliferation of cancer cells actually come from? If one could resolve such operating mechanisms—or rather, their abnormal operational mechanisms—solving cancer probably would not be all that difficult. Its operational efficiency is not particularly high, and it consumes a certain amount of energy by nature. Moreover, it is impossible for it to proliferate as directly as nanoweapons; its rate of proliferation is relatively slow. It is simply of a type that, although slow, is absolutely fatal.
