"Even if you do that, I still don't know anything."

Ibeiya did not seem to be faking it this time. From Xiao Lin's patient questioning, they found out that Ibeiya had planned on staying a few days after leaving the inn before she left Wildfire Town, but she suddenly felt a surge of danger in the morning. She had planned on leaving, but she fainted halfway through, and the town was empty the moment she woke up. 

"You suddenly fainted?" Lilith narrowed her eyes, obviously not believing such a vague explanation.

Ibeiya cried as she said, "I only felt a strange energy starting to surge in the town before I lost consciousness. I really don't know what happened."

"Why didn't you leave after that?" Xiao Lin asked.

"I'm afraid that's probably not possible anymore. Did you two not notice? The whole town has been enveloped by death energy. It's just like a cage we won't be able to escape. Any living person would rapidly approach death if they entered."
