The Era of Imaginary Numbers

No contact, no research, no discussion. The world runs on the cornerstone of "real numbers". Technology, superpowers, and all the laws that civilization relies on are defined by real numbers. And "imaginary numbers" are an absolute taboo written in the first line of the highest prohibition. It is described as an uncontrollable natural disaster, an unknown nightmare that led to the annihilation of the "Observer" project thirty years ago, and an indirect cause of the "invasion of other worlds." Josh, a bottom student who couldn't even pass the basic assessment, accidentally triggered a "return to zero" abnormal event during an ordinary assessment. When the red alarm symbolizing an absolute ban sounded for him, and when the afterimage of the missing history emerged in front of his eyes, Josh discovered that he might be the prohibited "regulation" itself. Now, the hunters have arrived.
