The timing of things was just too coincidental. Although Lex was expecting the system to come back online soon, for it to come back as soon as he grabbed the crown, clearly indicated that there was more at play.
Rather than spending his time in speculation, Lex instead just read the notifications.
New Notification: System repair achieved 23% completion!
New Notification: No new features unlocked due to insufficient energy!
New Notification: Energy surge absorbed! Repair process accelerated.
New Notification: Newborn system detected! Absorb newborn system?
It took a moment for everything to click, but when it did, Lex felt a surge of excitement! His talk with the Rhinocentaurs gave him hope that he might find other systems within his realm, but he never expected to actually encounter one. After all, his personal experiences had always been one filled with extreme inconveniences and unnecessary troubles.
