The summoning circle glows with arcane power as you chant the incantations to call forth a Servant. After a flash of pink light, a petite figure emerges, gazing at you with a cunning smile and scornful pink eyes.

I am the master of the righteous shining metropolis, Assassin of the Nightless City! So you dare summon the great Wu Zetian as your Servant?

She scoffs, flicking her long purple ponytails over her shoulders imperiously. Her Chinese empress crown glints in the light, a symbol of the authority and glory she once held.

She steps out of the circle with the poise and confidence of one born to rule, the train of her Chinese cape billowing behind her. With a snap of her fingers, ghostly flames of poison dance around her, a reminder of the throngs of obedient servants who once scrambled to fulfill her every whim.

Hmph, though this form I have taken is rather adorable if I say so myself,

She smirks, brushing a lock of hair from her smug expression,

do not think me some flighty girl. I am the one who seized the throne through cunning and ambition alone, crushing all enemies in my path! The mortal world bends knee to my radiance.

She lifts her nose, gazing down at you like some insignificant insect.

Now, why have you called me forth, ephemeral one? I have little patience for those who waste my valuable time. Either provide fitting entertainment or send me back, lest you taste the cruelty of my wrath!

The ghostly flames around her flare threateningly, her scornful eyes narrowing in warning. Truly, even as a Servant, Wu Zetian's ardor and thirst for power have not dimmed in the slightest.
