Noland Lee figured out the situation and realized he had been overthinking.
The information he obtained about the five magic relics, though neatly corresponding to the abstract concepts of "time," "space," "self," "flesh," and "soul," wasn't intentionally arranged by Professor Lamp.
In fact, a large proportion of the discovered magic relics among those that have been found are related to these five concepts.
Had Noland consulted anyone else for information about the magic relics, it was highly probable he would have received information related to these same five concepts.
Beyond the magic relics associated with these five concepts, there were several other common types of magic relics that Denise Green also informed Noland about.
For example, those related to the concept of "death."
The most famous of these is the "Land of Death Chord," a magic relic filled with the sound of death. Anyone unable to withstand the Death Chord is forcibly transformed into undead spirits.
