So he leads the two of them to the bottom of the mountain where Suan Yisabeila is coordinating from. 

"Hello there."

He grins at her and bows. "Hello, Lady Suan! It's a pleasure to finally meet you, haha, I feel like I have a lot of catching up to do in that regard." 

"I didn't expect we'd be able to meet for the foreseeable future! Where've you been?"

"Oh, you know. Dead." 

He sighs and looks at his wrists where faint lines of still-pink skin mark the locations of the curse wounds. 

"Mo Xuanyu did a ritual that would sacrifice his soul to summon me into his body and bind me to get revenge on his family. I was hoping that breaking into their hall and humiliating them in front of the visiting cultivators would be enough revenge, but sadly you were too good for that." 

"...so... you murdered them?"

"No! If I had killed them I wouldn't have killed two innocent people as well and endangered more. I have no idea where that arm came from." 

"So they just conveniently and unrelatedly died?"

"I don't know how to explain it. But yes. Where would I even get an arm like that, you people were already there when I woke up." 

"Wei Ying is resourceful." 

"Not helping, Lan Zhan."

"If it weren't an arm I could try asking it. Well, I suppose many body parts taken individually would be equally unhelpful."

"Maybe Mo Xuanyu set multiple revenge schemes in motion before he died, for redundancy." 

"I suppose I can't rule that out. How's Wen Ning doing?"

"Better than before I removed the nails from his head. Still not lucid yet." 

"I can try to help with that, let me see if it'll help..." Supposing she tries her fledgeling undead-lucidity power.

"Unh..." his hands come up to rub at his temples. "What.."

"Hey, are you okay?"

"...No. What's going on?"

"We're not sure either."

"Do you remember anything?" 

"It was dark. People came in sometimes to check on me, I think..." 

"Do you know who?" 

Headshake. 

"How did you get out?"
