Lu Xuanji slightly frowned, full of doubt.
Emperor Du Ling sighed inwardly, indeed so.
For cultivators from major clans, this is common knowledge; but for bottom-tier loose cultivators, it's a blind spot in knowledge.
Emperor Du Ling continued: "After Void Refining, cultivators only comprehend one type of mysteries, which makes the progress speed much faster. But if two types of mysteries are comprehended, the two will interfere with each other, increasing the difficulty of comprehension by tenfold. If three types are comprehended, the difficulty will double again. If four, five, and so on are comprehended, the difficulty will increase exponentially."
"When the realm is low, the interference of mysteries is relatively light. But as one enters the Harmonization Realm, the interference increases; at the Tribulation Crossing Realm, the conflict of mysteries intensifies."
