It was true that too much was as bad as too little. If the six billion earthlings living in the prison of reincarnation—six billion unyielding and defiant heroes—were regarded as 'energy sources', they would be extremely unstable and dangerous sources of energy. If one wanted to use such energy as fuel, they would have to be extremely prudent.
From the end of the twentieth century to the middle of the twenty-first century, it was the golden period for the steady and efficient utilization of such energy. Later, as the information explosion and the space technology grew more mature, it was very likely that mankind would develop the universe beyond Earth. At the very least, it was possible to develop the Moon and Mars on a large scale.
