A secret

"So what happened to Yuan Yuan?"

"If I'm not wrong, she had been attacked by something inside the violet water Swamp." Sima You said.

"Spirit Beast? What kind of spirit Beast will do this?" Due Ring thought over it for a moment. She couldn't think which spirit beast would give this kind of effect and was rather confused.

Sima You Yue stood up and said: "Mirage worm, it's a kind of transparent, small worm that is smaller than the size of a sesame seed. It's a mental based spirit worm, and whoever is bitten by it will enter a kind of fantasy, never to wake up. He will merely look like he is sleeping. Inside the fantasy, it's all beautiful dreams, so whoever is bitten ends up looking serene, constantly smiling. How long has she been asleep?"

"Ten days. Why?"
