"Where does pollution originate? What kind of existence is the source of everything? What great existence can casually pollute one world after another?"
The question asked by the big cat made Lu Ping'an pause. The next moment, he instinctively pulled out the answer from his memory.
"Isn't the pollution from the Exotic Realm....." This was the standard answer - the original source of all pollution was not from this world.
"Which Exotic Realm?" the big cat asked directly.
"How would I know? Many worlds have it, or rather all known worlds are polluted, but if you want to know the very first source..." Lu Ping'an couldn't answer that.
Not to mention he couldn't answer it, no book in the Special Service Team's library could answer this question.
"...I don't know." Lu Ping'an gave up his stubbornness and directly asked back.
"You know? Isn't this what you're supposed to tell me?" Lu Ping'an was somewhat expectant, he had been waiting for this 'answer' for a long time.
