"First of all, regarding Uncle Chu's ability to control others, perhaps Odin endowed him with the exact same power, though naturally not to the extent of Odin himself," Lu Mingfei explained, addressing the doubts Nono had raised one by one. "Secondly, the mask might be some kind of medium. Uncle Chu said that when Odin put the mask on him, he could feel a surging vitality being injected into his body. I suspect the mask enhanced the proportion of dragon blood in his Bloodline."
Nono pondered for a moment, then looked up at Lu Mingfei and said, "So whether it's Uncle Chu, Senior Brother Ye Sheng, or anyone else made to wear the mask, the ultimate reason their power grows is because the mask boosts their Bloodline. And with the proportion of dragon blood rising in their bodies, it becomes harder for them to maintain their sanity."
"Right, that's the logic," Lu Mingfei nodded. "When the dragon blood in the body reaches a certain level of purity, human thoughts are suppressed by the dragon's thoughts, bringing them infinitely close to something like a Ghouls. And individuals in this state are much easier to manipulate. When the mask shatters, the amplification from the dragon blood weakens accordingly, and it's very likely that the human portion of their sanity slowly recovers along with it."
