Every world possessed two defenses against foreign invasion: the World Garment and the rules of balance.
The rules of balance stemmed from the pressures within and outside a world. Compared to the shadowy void beyond the world, the unique rules and elemental power derived from the will of the world's origin created a powerful outward pressure, repelling foreign invaders.
As for the rules of the World Garment, they were a form of self-protection evolved after Chaos creatures developed a world. Like bolts of lightning woven into a vast net, they protected the world within.
Cleverly, however, there were enormous gaps between the lightning threads of this World Garment's protective layer.
Such gaps meant nothing to high-level creatures, for their bodies were simply too enormous to squeeze through. Low-level creatures, however, could slip silently through those gaps. That was the origin of Demon-Hunting Merit Shadow Wizards.
However...
Green's World Garment rule constitution could ignore the very rule that the world's guardians relied upon as the world's strongest protective constable!
Green did not immediately begin his clandestine invasion of the Parasitic Spore World. Instead, he cautiously drifted around its outer perimeter, sensing the fluctuations of spacetime power as though searching for a weak point in the outer shell of a great box.
More than ten days later, Green finally found something: a weak point in the Parasitic Spore World's spacetime.
Without question, this was the spacetime passage between the Spiritfolk World and the Parasitic Spore World!
A weak point in a world's spacetime meant that its strongest defensive forces were gathered there. The power of the entire Parasitic Spore World was concentrated in that location. If Green foolishly launched his invasion from there, he would probably fail within minutes.
Thus, the region farthest from this place was the safest.
