"How?"

"Well, it's a turtle, right? Or a Xuanwu, close enough. It should be way weaker inside the shell."

...well yes, but shells are as difficult to carve doors in as they are to stab. Lan Zhan blinks at her.

"And shells have natural openings so, uh, if you're still up for being a distraction..."

"You'll go in... around the tail? Is there room?"

"Well, I was thinking around the neck, but the tail might also work, sure."

"I don't want you to be near the head." Even if the head is distracted.

Unless there won't be enough room at the tail end, somehow? Lan Zhan feels woefully unknowledgeable about turtle anatomy and monstrous snake-turtle anatomy in particular.

"I'll check the tail and circle around if it doesn't work."

"I'll use a torch to draw its attention?"

Kiss. "Alright. Be careful." 

Kiss. She'll try, of course. This is almost certainly going to be bad for her injuries, but not as bad as slowly starving and/or bleeding to death in a cave. "You be more careful."

"You be more careful! You're hurt way worse than I am to start with."

"You are more foolish than I am to start with."

POUT. "Why is my Lan Zhan so mean to me." Kiss. 

My Lan Zhan, eeeee. Kisskiss.

Lan Zhan pushes herself up on the cave wall; it's time to find a useable torch and ideally other weapons.

Wei Ying helps her find a torch and collect some bow strings for exciting Lan chord techniques and hugs her before circling around to the other side of the pond.

She waits for Wei Ying to be in position before lighting the torch and slamming its metal base against rock as loudly as she can.

RRAAAAAAAR. 

Wei Ying wastes the barest fraction of a section confirming that Lan Zhan is still okay before diving into the water where the Xuanwu's tail is thrashing the water into a froth. 

Climbing into the beast's shell without getting whacked is no small thing, especially without dropping or cutting herself on the pilfered Wen sword that she has to do the deed with, but she manages it. It's mostly dry inside, but the resentful energy that chokes the space is not an improvement. 

Stab. Stab. Stab. 

The Xuanwu is busily menacing Lan Zhan when it suddenly is very distracted from the distraction. It turns its head towards its own rear.

Lan Zhan hisses and hurls the torch at its nearest eye.

It whips its head back and tries to bite her. 

She jumps back; something in her leg crunches unpleasantly when she kicks off. When she lands, it buckles and tips her backwards. Even as she hits the rock Lan Zhan is desperately grasping for anything within reach to bang or throw to distract the creature from Wei Ying.

Nothing immediately comes to mind. The Xuanwu hisses at her for another second before continued butt stabbing draws its attention back to Wei Ying. 

Well Crap. This is less stabbing than Wei Ying had hoped to accomplish before this thing came after her. On the plus side, it's relatively difficult for this thing to maneuver its own head in the back side of its shell.
