Edward Kirsten's grandfather had been researching it for ages, making the time frame too vast.

"By the way, Enigma, do you know why it's called '319'?" Edward Kirsten's voice laughed, "Because Enigma wanted to leave her brother, and her brother was very angry.

Listening to this, Allonzo Hobson's emotions went from shock, anger, and heartache to admiration.
