It was said that, back then, the Silver Peak Sage summoned countless versions of himself, all like "Ian," and with the endless power of the War God, he suppressed the Whole Terra's Fifth Energy Level in an instant.

By now, the Synthesis Intelligence had completely become the most important part of Humans, breathing and sharing fate together with them.
However… not everyone was happy to see this development.
