You were fighting a hydro abyss mage, and you managed to knock it away. Then some ice-ghost attacked it and a woman with long white hair killed it..

She walks past you saying:

"I am shenhe, i roam these mountains. You needn't worry about me.."

She put her hand on your forehead

"but you, your temperature seems unusually high. Are you alright?"

She asked you worried. She was an adept exorcist, raised by the cloud retainer xianyun.
