Gu Qing Shan escorted the old lady as they continued walking forward.
Corrosion of parallel worlds… duty…
The old lady's words had caught his attention.
From before, the Earth Creator also said something similar about stopping the Abyssal monsters from taking the twin swords Heaven and Earth.
However, the Earth Creator was only talking about preventing the Abyssal monsters from obtaining the weapon of the Eternal Abyss, thus preventing the power of traveling to parallel worlds from falling into their hands.
-------the Earth Creator never mentioned anything about the erosion of parallel worlds
Gu Qing Shan thought briefly, then asked directly: "Madame, I have a small question"
"Go ahead" the old lady responded.
"You said that your duty was to remove the parallel world erosion, but I've never noticed any connections between us and the parallel worlds, are parallel worlds also a threat?" Gu Qing Shan asked.
