Lan Wangji approaches, maintaining the immobilizing tune. 

"Is everyone alright?" 

"Checking." Now what.

Previously dead are still dead; everyone else is fine. 

"Everybody currently alive is stable in my range."

Wangji attempts to exorcise the arm. This proves too difficult to do by himself in the field, but he can calm it down enough to imprison in a qiankun pouch for safe transport back to Cloud Recesses later. The fierce corpses...

Wangji studies them silently for a moment. 

"These are the work of demonic cultivation. Not naturally occurring." 

"It must have been that Mo Xuanyu guy!" Jingyi says excitedly. "The Mos said he used to be a cultivator, and he had his face painted like he was a hanged corpse, and he was really weird and he tried to mess with the spirit-attracting flags but Senior Suan stopped him." 

"Mn. Where is he now?" 

"Uh..." 

Oh for crying out loud. Will they find him in the next six hours.

Well, not in the first six hours, but they can tell her where they looked that time and she can tell them to try elsewhere, and eventually it is concluded that he's definitely not in Mo Village anymore. 

[Found him,] Wangji reports in the vision where he goes down the road in the opposite direction from the one the Juniors came down. 

She points him that way in reality.

Oh come on this is not fair how did Lan Zhan know exactly where to find him??? He'd thought leaving as soon as Lan Zhan showed up would be enough, but no. Dammit, this is what he gets for not leaving sooner. Probably it would have been fine. Doesn't the mighty Hanguang-Jun have better things to do. 

Lan Wangji dismounts from his sword. "You are Mo Xuanyu," he says calmly. 

"Ahahaha, wow, the great Hanguang-Jun has heard of me! I'm incredibly flattered," he says, bowing from his position on the (stolen??? whatever, it wasn't like the Mos were using it) donkey. 

"At Mo Manor, the entity which killed six people was fought by five fierce corpses. Those corpses did not arise naturally through their own anger, but were raised by way of demonic cultivation. Besides the Lan disciples which were originally sent to deal with the walking corpses in the area, you are the only one with any kind of cultivation background who was present." 

"That doesn't prove it was me! Maybe one of your little disciples has been doing things they shouldn't have." 

"...Fine. But I only did it because it was an emergency! Would you rather one of your disciples had gotten killed?"

"No." 

"So, really, you have to agree, I didn't do anything wrong!" 

"Yes." 

"Wait, what?"

"You did not do anything wrong." 

"What, is the great Hanguang-Jun tolerating demonic cultivation now? What would people think if they knew?" 

"You just said I should." 

"Haha, you should know better than to listen to me, didn't anybody tell you I'm a lunatic?"

"You do not seem like one to me." 

"Woooooow, all this praise from Hanguang-Jun! I can't take it!" 

He grins.
