It was said that the theory of the human body reactor originated from an extremely developed civilization whose technology had advanced to the extent that they could create matter and life from nothing. Then, they became fascinated with fantasy and immortal-hero cultures and designed a way to disguise real technology as fantasy and immortal-hero technology, thus leading to the development of the human body reactor theory.
This theory was very strange and full of doubts, yet it was genuinely effective, and no one could understand the rationale behind it.
The inventors of this theory were called the Zenith Star people.
Some researchers believed that the technological level of the Audro continent could catch up with the Zenith Star people in the distant future, and by then, all residents of the Audro continent would be known as the Divine Clan, who could happily create alternative worlds to frolic in.
